Abstract

The invention provides a damping and heat-dissipating device for a rolling bearing. The damping and heat-dissipating device comprises a bearing base, a bearing gland, a revolving shaft, a damping rubber ring, a wave spring and the rolling bearing, wherein the wave spring is arranged in a gap between the side face of the rolling bearing and the bearing base. The wave spring is made of beryllium bronze, so that the wave spring has higher heat conductivity and can be used for effectively transferring heat generated by high-speed rotation of the rolling bearing. According to the damping and heat-dissipating device, the wave spring has a semi-circular arch-shaped structure, so that the elasticity is improved, the radial contact rigidity of the rolling bearing is reduced, and the vibration impact of the rolling bearing is reduced. The service life of the rolling bearing is prolonged, so that the service life of a turbo molecular pump is prolonged.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and heat dissipation of rolling bearings, and in particular relates to a vibration reduction and heat dissipation device of rolling bearings. The invention can be applied to the rolling bearing structure of the turbomolecular pump, can prolong the service life of the rolling bearing, and further improve the service life of the turbomolecular pump. Background technique [0002] The turbomolecular pump includes a moving impeller and a stationary vane. The rotating shaft of the moving impeller is supported in the bearing seat through a rolling bearing device, and the rolling bearing is mainly lubricated with oil or grease. Since the impeller of the turbomolecular pump rotates tens of thousands of revolutions per minute, the vibration wear and temperature rise of the rolling bearing have a great influence on its life. The axial and radial directions of the outer ring of the rolling bearin...
