Bearing chamber suitable for rolling bearing

Abstract

The invention discloses a bearing chamber suitable for a rolling bearing. The bearing chamber comprises a shaft sleeve, a bearing body, a bearing body gland and an oil retainer, the bearing body is arranged on the shaft sleeve, the bearing body gland is fixed on the bearing body, the oil retainer is fixed on the lower surface of the bearing body gland, a bottom cavity in the shaft sleeve is an oil chamber, a mounting chamber for mounting a bearing is formed among the shaft sleeve, the bearing body and the lower surface of the oil retainer, a buffer chamber is formed between the bearing body gland and the upper surface of the oil retainer, the oil chamber, the mounting chamber and the buffer chamber communicate through a circulating oil path, and a plurality of air cooling blades are further arranged on the outer side face of the shaft sleeve. The invention relates to a bearing chamber with efficient heat dissipation performance, and therefore heat transmission can be carried out through forced air cooling so as to provide necessary lubricating and cooling conditions for the bearing.

Description

technical field [0001] The invention relates to rolling bearing technology, more specifically, to a bearing chamber suitable for rolling bearings. Background technique [0002] Rolling bearing is the most widely used mechanical support, mainly relying on the rolling body to support the relative rotation, swing, and reciprocating linear motion between the bearing and the base. Compared with sliding bearings, it has small power loss, wide application conditions, easy maintenance, and high interchangeability. advantage. However, because the motion mode of the rolling bearing is relatively complex, based on the rolling motion, there is also a sliding motion component. The repeated action of the contact load on the rolling body or the rolling surface of the ring in the working state generates a large amount of heat. If the heat cannot be taken away in time, the temperature of the rolling bearing will rise rapidly, causing the failure of the lubricating medium, which will cause t...

Problems solved by technology

However, this method increases the volume of the bearing body and increases the cost. At the same time, the heat dissipation efficiency of this method is limited. For high-speed and heavy-duty working environments, it is difficult to provide lubrication and cooling conditions for the bearings.
