Bearing fixing device

Abstract

The invention is suitable for the field of mechanical structure design, and relates to a bearing fixing device. The bearing fixing device is characterized in that: the bearing fixing device comprises pins, a bearing pedestal, an outer lining, an inner lining, and a bearing; the bearing pedestal is a single-lug bearing pedestal; the outer lining and the inner lining are provided with shoulders at one side; through holes are disposed at the outside of a bearing hole of the bearing pedestal; the outer lining and the inner lining are respectively provided with through holes; the bearing is pressed in the inner lining, a side of the bearing is contacted with the shoulder of the inner lining and then the inner lining is installed in the outer lining; the bearing is contacted with the shoulder of the outer lining; the shoulder of the inner lining and the shoulder of the outer lining are respectively disposed at each side of the bearing; the outer lining is pressed in the bearing pedestal; and the pins are inserted into the through holes of the outer lining, the through holes of the inner lining and the through holes of the bearing pedestal. The bearing fixing device is advantageous in that axial bearing capability of the bearing is largely enhanced on a premise of not influencing radial bearing capability of the bearing; cases of axial sliding and shedding will not occur when the bearing bears frequent axial load; the axial shedding load of the bearing can be calibrated accurately by utilization of that the pins have designability; and the convertibility of the bearing is improved.

Description

technical field [0001] The invention is suitable for the field of mechanical structure design and relates to a bearing fixing device. Background technique [0002] Usually, the bearing and the bearing support are connected by interference fit, such as figure 1 shown. This bearing fixing method can better transmit the radial load received by the bearing, but the amount of interference fit is limited and the axial load capacity is low; when subjected to frequent axial loads, the probability of the bearing falling off from the bearing support is relatively high. The reliability is low; the installation technology of bearing interference fit is difficult, and the amount of interference cannot be precisely controlled, and the axial bearing capacity of the bearing cannot be calibrated; Replaceability is poor. [0003] Adhesives are also usually used to fix the bearing to the bearing support, such as figure 1 shown. Due to the weak bearing capacity of the adhesive, it is easy ...
