1 GENERAL INFORMATION 1.1 SYMBOLS AND UNITS OF MEASURE
An fS fTP [N] The admissible thrust load represents the force which can be applied axially to the gear unit’s shaft, along with the rated radial load. The service factor is a coefficient representing the severity of the duty for the operating cycle. The adjusting factor takes into account the influence of the ambient temperature in calculating the computational torque. This factor is relevant for worm gear units. The gear ratio is expressed as the relationship of the input shaft speed to the output shaft speed.

1.2 INTRODUCTION TO THE ATEX DIRECTIVES 1.2.1 EXPLOSIVE ATMOSPHERE
Under the provisions of Directive 94/9/EC, an explosive atmosphere is defined as a mixture: a. b. c. d. of flammable substances, whether gas, vapour, mist or dust; with air; in certain atmospheric conditions; in which, following ignition, combustion spreads to the entire unburned mixture (note that in the case of dust, the entire quantity of dust is not always completely burnt after combustion).

An atmosphere which may potentially be transformed into an explosive atmosphere due to operating and/or ambient conditions is defined as a potentially explosive atmosphere. The products governed by Directive 94/9/EC are intended for use only in a potentially explosive atmosphere defined in this way.

1.2.2 EUROPEAN HARMONISED ATEX STANDARDS
The European Union has issued two harmonisation guidelines in the area of health and safety. These directives are known as ATEX 100a and ATEX 137. Directive ATEX 100a (EU/94/9/EC) stipulates the minimum safety requirements for products intended for use in explosion risk areas within the member countries of the European Union. The directive also assigns such equipment to categories, which are defined by the directive itself. Directive ATEX 137 (EU/99/92/EC) defines the minimum health and safety requirements for the workplace, for working conditions and for the handling of products and materials in explosion risk areas. The directive also divides the workplace into zones and defines the criteria for the application of product categories in said zones. The following table describes the zones into which the user of a plant, in which an explosive atmosphere may occur, is required to divide the equipment application areas.
Zones Gaseous Dusty atmosphere atmosphere G D
0 1 2 20 21 22

Type of danger
Permanent Potential Minimal

BONFIGLIOLI RIDUTTORI gear units selectedin this catalogue are suitable for installation in zones 1, 21, 2 and22, as highlightedin grey in the above table. Electric motors described in this catalogue are certified in category 2D (125°C max. temperature) and therefore suitable for installation in zones 21 and 22. As from 1 July 2003 the ATEX directives come into force throughout the entire European Union, and replace existing conflicting national and European laws on explosive atmospheres. It should be emphasised that, for the first time, the directives also govern mechanical, hydraulic and pneumatic equipment, and not only electrical equipment as has been the case so far. With regard to the Machinery Directive 98/37/EC it should be noted that directive 94/9/EC is a set of extremely specific requirements dedicated to the dangers deriving from potentially explosive atmospheres, whereas the Machinery Directive contains only very general explosion safety requirements (Annex I). Consequently, as regards protection against explosion in potentially explosive atmospheres, Directive 94/9/EC (ATEX 100a) takes precedence over the Machinery Directive. The requirements of the Machinery Directive apply to all other risks regarding machinery.

1.2.3 LEVELS OF PROTECTION FOR THE VARIOUS CATEGORIES OF EQUIPMENT
The various categories of equipment must be able to operate in conformity with the Manufacturer’s operational specifications, at certain defined levels of protection.

1.2.4 DEFINITION OF GROUPS (EN 1127-1)
Group I Applies to equipment intended for use underground in parts of mines and those parts of surface installations of such mines, liable to be endangered by firedamp and/or combustible dust. Group II Applies to equipment intended for use in other places liable to be endangered by explosive atmospheres. BONFIGLIOLI RIDUTTORI products may not therefore be installed in mines, classified in Group I and in Group II, category 1. To summarise, the classification of equipment into groups, categories and zones is illustrated in the table below, whereby the availability of BONFIGLIOLI RIDUTTORI products is highlighted in grey.

1.2.5 DECLARATION OF CONFORMITY
The Declaration of Conformity, a copy of which is available in this catalogue, is the document which attests to the conformity of the product to Directive 94/9/EC. The validity of the Declaration is bound to observance of the instructions given in the User, Installation and Service Manual for safe use of the product throughout its service life. The instructions regarding ambient conditions are of particular importance inasmuch as failure to observe them during operation of the product renders the certificate null and void. In case of doubt regarding the validity of the certificate of conformity, contact the BONFIGLIOLI RIDUTTORI technical department.

1.3 USE, INSTALLATION AND MAINTENANCE
The instructions for safe storage, handling and use of the product are given in the unit’s User, Installation and Service Manual. This can be downloaded from www.bonfiglioli.com/atex.html where the manual is available in PDF format in a number of languages. This document must be kept in a suitable place, in the vicinity of the installed gear unit, as a reference for all persons authorised to work with or on the product throughout its service life. The Manufacturer reserves the right to modify, supplement or improve the Manual, in the interests of the User.

1.4 SELECTING THE TYPE OF EQUIPMENT 1.4.1 SELECTION PROCEDURE:
Determine the application service factor fS in relation to the type of load (K factor), number of starts per hour Zr and hours of operation per day. Now determine the power required at the motor shaft:

The efficiency value ? ηd ? can be determined as follows (approximately):
Worm gear unit efficiency - n1=1400

The selection procedure now depends on the type of gear unit, as follows: a. gear unit equipped with IEC motor fitting b. gear unit equipped with solid input shaft. Proceed as follows:

1.4.2 SELECTING A GEARMOTOR
a. Determine service factor fs as formerly specified. b. Determine power required at gearbox input shaft:

c. Consult the gearmotor rating charts and locate the table corresponding to normalised power Pn:

7

Unless otherwise specified, power Pn of motors indicated in the catalogue refers to continuous duty S1. For motors used in conditions other than S1, the type of duty required by reference to CEI 2-3/IEC 34-1 Standards must be mentioned. For duties from S2 to S8 in particular and for motor frame 132 or smaller, extra power output can be obtained with respect to continuous duty. Accordingly the following condition must be satisfied:

The adjusting factor fm can be obtained from table here after.

1.4.3 GEAR UNIT WITH MOTOR FITTING
- with reference to the rating charts, identify the gear unit which, for the required speed n2, provides a rated power Pn1 such that:

- Select an electric motor rated:

- Finally, check that the motor/gear unit combination generates a safety factor equal to or greater than the service factor for the application in question, in other words:

- If the selected gear unit is of type C112, C212 or C312 with ratio i > 40 ,operating with a number of hourly starts Z > 30 ,correct the service factor taken from the graph by a factor of 1.2. fs . Finally, check that the recalculatedservice factor fs still satisfies the condition S

1.4.4 SPEED REDUCER WITH SOLID INPUT SHAFT
- Calculate the value of the computational torque:

ftp Helical gear units C, A, F, S
Type of load ftp = 1 K1 uniform load K2 moderate shock load K3 heavy shock load

Worm gear units VF, W
Ambient temperature [°C] 20° 30° 40° 1.00 1.00 1.06 1.00 1.02 1.12 1.00 1.04 1.17

- for the speed n2 closest to that required, select the gear unit with a rated torque Mn2 equal to or greater than the computational torque Mc2, in other words:

1.4.5 POST-SELECTION CHECKS
Once the gear unit or gearmotor has been selected, we recommend checking the selection as follows: Momentary peak torque The momentary peak torque is of the order of 200% of the rated torque Mn2. Check that the point value of the peak torque satisfies this condition and equip the installation with a torque limiter if necessary. Radial load The catalogue gives the values of the maximum admissible radial load for both the input shaft ? Rn1 ? and the output shaft ? Rn2 ?. These values refer to a load applied at the shafts’ centre lines and must always be greater than the actually applied load. See paragraph: Radial loads. Thrust load Check that the thrust component of the load does not exceed the maximum admissible value as given in the paragraph: Thrust loads.

1.4.6 OPERATING CONDITIONS FOR ATEX-SPECIFIED EQUIPMENT
Ambient temperature -20°C < to < +40°C. The gear unit must be installed in the mounting position specified in the order and given on the nameplate. Any deviation from this requirement must be approved in advance by BONFIGLIOLI RIDUTTORI. Do not under any circumstances install the gear unit with its shaft in an inclined orientation, unless previously authorised to do so by the BONFIGLIOLI RIDUTTORI Technical Service Department. The speed of the motor mounted to the gear unit must not exceed n = 1500 min-1. Should the gearbox be connected to an inverter driven motor the latter must be explicitly suitable for the purpose and used in full compliance with the instructions set forth by the manufacturer. Under no circumstances the setting of the inverter shall allow the motor to exceed the maximum speed permitted (1500 min-1) or overload the gearbox itself. All the instructions in the User Manual (www.bonfiglioli.com/atex.html) regarding installation, use and routine maintenance of the unit must be followed in full.

1.4.7 SERVICE FACTOR - [ fs ]
This factor is the numeric value describing reducer service duty. It takes into consideration, with unavoidable approximation, daily operating conditions, load variations and overloads connected with reducer application. In the graph below, after selecting proper “daily working hours” column, the service factor is given by intersecting the number of starts per hour and one of the K1, K2 or K3 curves. K_ curves are linked with the service nature (approximately: uniform, medium and heavy) through the acceleration factor of masses K, connected to the ratio between driven masses and motor inertia values. Regardless of the value given for the service factor, we would like to remind that in some applications, which for example involve lifting of parts, failure of the reducer may expose the operators to the risk of injuries. If in doubt, please contact our Technical Service Department.

Acceleration factor of masses - [K] This parameter serves for selecting the right curve for the type of load. The value is given by the following ratio:

where: Jc moment of inertia of driven masses referred to motor shaft Jm moment of inertia of motor

2.5 ADMISSIBLE OVERHUNG LOADS 2.5.1 RADIAL LOADS 2.5.1.1 CALCULATING THE RESULTING OVERHUNG LOAD
External transmissions keyed onto input and/or output shaft generate loads that act radially onto same shaft. Resulting shaft loading must be compatible with both the bearing and the shaft capacity. Namely shaft loading (Rc1 for input shaft, Rc2 for output shaft), must be equal or lower than admissible overhung load capacity for shaft under study (Rn1 for input shaft, Rn2 for output shaft). OHL capability listed in the rating chart section. In the formulas given below, index (1) applies to parameters relating to input shaft, whereas index (2) refers to output shaft. The load generated by an external transmission can be calculated with close approximation by the following equation:

Kr = 1

Kr = 1.25

2.5.2 THRUST LOADS An1, An2
Permissible thrust loads on input [An1] and output [An2] shafts are obtained from the radial loading for the shaft under consideration [Rn1] and [Rn2] through the following equation:

The thrust loads calculated through these formulas apply to thrust forces occurring at the same time as rated radial loads. In the only case that no overhung load acts on the shaft the value of the admissible thrust load [An] amounts to 50% of rated OHL [Rn] on same shaft. Where thrust loads exceed permissible value or largely prevail over radial loads, contact Bonfiglioli Riduttori for an in-depth analysis of the application.

2.8.1 - HYBRID IMPUTS For mounting to non-standardised electric motors, the motor coupling for W series worm gear units can be configured with hybrid input shaft/flange combinations, which do not correspond to IEC standards. The shaft/flange combination is given in the designation which specifies the diameters as shown in the following example:

19 / 105 Figures before the stroke Figures after the stroke

The following table gives the gear ratios that hybrid flange/input shaft combinations are available for:
