查询词典 bearings

The bearing is a kind of important part in the machine for supporting spindles. It is an urgent question for discussion to solve how to reduce the friction between bearings and shafts and how to improve the efficiency. Devisers have done many works to improve the performance of bearings, which include structure, lubricant, subtract friction material, and manufacturing process aspect.

轴承是机器中用来支撑轴的一种重要零件，如何减少轴承与轴之间的动摩擦，提高机械效率，一直是滑动轴承设计者所研究和迫切需要解决的课题，设计者们在轴承结构、润滑剂、减摩材料及制造加工工艺等方面进行了大量的改进工作。

Double row tapered hole cylindrical roller bearings with inner ring and shaft are tapered 1:12, bearing lock nut with a round led a bearing in the axial displacement of the inner ring bearings and expansion, to reduce or eliminate Bearing radial clearance purposes.

圆锥孔双列圆柱滚子轴承的内圈和配合轴径均为1：12圆锥，用圆螺母锁紧轴承则使轴承在轴向产生一个位移并使轴承的内圈膨胀，从而达到减少或消除轴承径向游隙的目的。

Engine work, if crude oil filter was a serious blockage of impurities, or due to low temperatures when the oil viscosity changes, the main oil缺油Road will be the engine will lose lubrication, this is very dangerous, especially in the main bearings and connecting rod bearings, if there is no oil will be burned, bearing alloy heat due to friction loss and even journal welded together, eventually forcing the engine to stop working.

发动机工作时，若机油粗滤器被杂质严重淤塞，或者由于气温低而机油粘度变大时，主油道就会缺油，发动机就会失去润滑，这是很危险的，特别是主轴承和连杆轴承，如果没有润滑油会烧坏，轴承合金会因摩擦发热而流失，甚至和轴颈熔焊在一起，最终迫使发动机停止工作。

Most of the CPU fan with ball bearings between the use of lubricants, with the aging of lubricants, the lubricating effect on getting worse, leading to friction between the ball and large bearings.

大部分CPU风扇的滚珠与轴承之间会使用润滑油，随着润滑油的老化，其润滑效果就越来越差，导致滚珠与轴承之间摩擦力变大。

All the actuators of the three-axis turntable are brushless torque motors, all the bearings are aerostatic air bearings, so the friction caused by these elements can be neglected. The main source of friction is the metal-to-metal friction on the slip rings. Hence the "Columb+Viscous+Static" friction model is used here for analysis.

由于三轴转台的驱动系统选用的是无刷电机，轴承则采用的是气浮轴承，轴系上的摩擦力已大大降低，三轴转台上的摩擦主要是滑环轴上金属对金属的摩擦，所以文中选用&库仑＋粘滞＋静摩擦&的摩擦模型来进行分析。

In most applications, CSB bearings can be fitted by press. For this procedure, a mandrel and a press machine are used, it is forbidden to hit the bearing in order to avoid deformation of bearings. The housing inner side should smooth without contamination.

通常情况下，轴承可以采用压力装配的方式进行安装，装配时应采用芯轴慢慢压入，禁止直接击打轴承以免产生变形，装配前应确保座孔内表面光洁无异物。
