JDB-650 固体镶嵌润滑轴承 (标准公差尺寸见第07页) Solid Lubricant Embedded Bushing
JDB-650固体镶嵌润滑轴承,是在高力黄铜(ZCuZn25Al6Fe3Mn4)的基体上,镶 嵌石墨或MoS2固体润滑剂的高性能固体润滑产品。它突破了一般轴承依靠油膜润滑 的局限性。在使用过程中,通过摩擦热使固体润滑剂与轴摩擦,形成油、粉末并存润 滑的优异条件,既保护轴不磨损,又使固体润滑特性永恒。它的硬度比一般铜套高一 倍,耐磨性能也高一倍。目前已广泛运用于治金连铸机,注塑机、列车支架、轧钢设 备、矿山机械、船舶、气轮机等高温、高载、低速重载等场合使用。 JDB-650 solid lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body It breaks through the limit of general bearing whose lubrication depends on oil film. So it is suitable for high temperature, heavy duty, anti-Corrosion. or where oil is hard to be introduced It performance doubles both on hardness and wearfriction. It is now widely applied in successive casting machines, steel rollers in metallography, mineral machine, ships. steam turbine. hydraulic turbines and injection molding machines for plastics.

JDB-600 油沟铜衬套 Oil Groove Bronze Bushing
JDB-600铜套,是一种以油沟涌油作为润滑的高力黄铜轴承。该产品具有传统的锡 青铜轴承功能,由于采用高力黄铜(ZCuZn25Al6Fe3Mn4)后,它的HB硬度提高了一 倍,所以在低速的场合使用该产品,比一般青铜套寿命可以延长一倍,而且其承载压 力大,能适应重载的场合使用。并可按客户要求提供如下材质。 JDB-600 copper sleeve, is a kind of groove Bay oil as lubrication oil of high strength brass bearings. The product has a function of the traditional bronze bearings, the use of high strength brass (ZCuZn25Al6Fe3Mn4), its hardness HB doubling the occasion so low to use the product, than the average life span can be extended twice bronze sets, and its bearing pressure, can adapt to overloaded occasions.

轴承的选型与计算 Bearing Selection & Calculation
轴承选型 Bearing Selection
滑动轴承根据不同的工况条件设计了不同的轴承材料。用户在使用和设计时应当根据轴承的使用温度、轴承的承载面 压、线速度、耐磨性能要求、运动类型、安装情况、轴承成本等各方面因素综合考虑。 Bush have developed kinds of bearing material according to difference work condition, the user can select the material base on bearing work environment, load, speed, wear, resistance request, moving method, installation, the cost of the material etc.

面压计算 Bearing Load
直套、翻边轴承 Cylidrncal bushes、flange bushes
P= F dL F = 轴承载值 Load (N) (N/mm2) d = 轴径 Shaft (mm) L = 轴承长度 Bearing Leagth (mm) F = 垫片承载值 Load (N)

P= 4F (D -d )π

(N/mm2)

D = 垫片外径 Washer OD (mm) d = 垫片内径 Washer ID (mm)

由于受配合间隙、材料强度、轴承倒角、内部 油槽等原因的影响,轴承的真正承载面压(Pact)会大于理论计算值 (Pmean)。 As the factor of clearance, bushes chamfer, oil groove etc. The actually load (Pact) is higher than theory of calculation(Pmean).

线速度计算 Velocity
旋转运动 Rotating motion
V= dnπ 1000×60 (m/s) d = 轴径 Shaft (mm) n = 转数/分 Rpm

摇摆运动 Oscillating motion
V= dcθπ 1000×360×60 d = 轴径 Shaft (mm) (m/s) c = 摇摆频率 Frepuency(次数/分) θ= 摇摆角度 Oscillating angle

往复运动 Reciprocating motion
V= 2sc 60 (m/s) s = 行程长度 (m) c = 往复频率 Frepuency(次数/分)

PV值计算 PV=P×V (N/mm2×m/s)
PV是指轴承在一定的承载和线速度条件下的乘积之和。设备的PV值与轴承的使用寿命承反比关系,因此建议设计时设备 的PV取值尽量使用比较低的安全PV值,以确保轴承会有更长的使用寿命。同时也要考虑设备上轴承实际的承载、线速 度、使用温度等不能超过所选择材料的极限值,并尽可能地小。 PV is the product ot the specific bearing load P and the sliding speed V which is very important design data. We recommend design lower PV value will lead to longer serive life. Also don't exceed the max. Of material load, speed, temp. And lower if possible.

密封 Seal
金属塑料基自润滑轴承允许一些不会损害轴承表面材料的异物 进入,但当异物的侵入增加或高碾磨型物质进入时应当安装合 适的密封圈以提高轴承的使用寿命。 If increased levels of contamination occur or the bearing is used in an aggressive environment, the bearing section should be protected from dust and containment. The normal solution is to re-design the surrounding structure so that the contamination cannot reach the bearing section. If the contamination is critical, a collar of grease or a shaft seal is recommended.
