Radial rolling bearing seat assembly structure with good vibration absorption

Abstract

The invention relates to a radial rolling bearing seat assembly structure with good vibration absorption. The structure comprises a bearing seat and a radial rolling bearing, wherein the radial rolling bearing consists of an inner ring, an outer ring, a rolling body and a retainer and is provided with an axial stop groove; the inner ring is matched with a shaft and rotates together with the shaft; the structure also comprises a metallic vibration absorption ring, wherein the vibration absorption ring is arranged between the bearing seat and the outer ring of the radial rolling bearing, the outer side and the bottom of the vibration absorption ring consist of a U-shaped outer edge and a bottom edge in a mode of rotating by using the central line of the shaft as a rotating center, and the inner side of the vibration absorption ring consists of a U-shaped inner edge in a mode of continuously rotating around the rotating center in equal clearance, so that the petal-like and roughly rotary vibration absorption ring, the inner side of which is provided with an equal central angle gap, is formed; the outer side of the vibration absorption ring is matched with and fastened to the bearing seat; and the protrusion on the petal-like body of the vibration absorption ring is embedded and limited in the axial stop groove of the radial rolling bearing. The structure has the advantages of good vibration absorption, low working noise and long service life of the bearing.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an assembly structure of a radial rolling bearing seat with good damping performance. Background technique [0002] In the prior art, radial rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. In most cases, the inner ring matches the shaft and rotates together with the shaft; It plays a supporting role; the rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, and the cage can make the rolling elements evenly distributed, prevent the rolling elements from falling off, and guide the rolling elements to rotate for lubrication. Rolling bearings are easy to use and maintain, reliable in operation, and good in starting performance; the disadvantage is that the radial rolling bearing seat of the prior art has poor vibration damping ability. The additional vibration force of the dy...

Problems solved by technology

Rolling bearings are easy to use and maintain, reliable in operation, and good in starting performance; their disadvantage is that the radial rolling bearing seat of the prior art has poor vibration damping ability. The additional vibration force of the dynamic unbalance generated by the rotor's own rotation is also subjected to the instantaneous impact force generated by the irregular random vibration during the driving process of the vehicle, especially the impact force of the instantaneous high-frequency vibration, resulting in the contact pressure between the rolling body of the bearing and the inner and outer rings. The stress is multiplied, and the damage to the bearing is great, resulting in a loud noise when the shaft rotates at high speed, and the bearing life is low, so the structure of the bearing seat needs to be improved
