Novel bearing with base

Abstract

The invention discloses a novel bearing with a base. The novel bearing with the base comprises a bearing mounting base, as well as a front side fixed end cover and a back side fixed end cover which are mounted on the bearing mounting base spirally, wherein a front end bearing, a bearing inner ring spacer bush and a back end bearing are embedded in a bearing mounting hole of the bearing mounting base; the periphery of the bearing inner ring spacer bush is sleeved with a bearing outer ring spacer bush; a front side inner ring pressing ring is embedded in a front side end cover through hole of the front side fixed end cover; a front side spring is mounted between the front side inner ring pressing ring and the front side fixed end cover; a back side inner ring pressing ring is embedded in a back side end cover through hole of the back side fixed end cover; a back side spring is mounted between the back side inner ring pressing ring and the back side fixed end cover; the bearing outer ring spacer bush comprises a front side outer ring spacer bush and a back side outer ring spacer bush; a pre-tightening oil pressing cavity is formed between a back side spacer bush extending part at the end part of the back side outer ring spacer bush and the inner wall of the bearing mounting hole; the bearing mounting base is provided with an oil passing hole. The novel bearing with the base can adjust the bearing pre-tightening force according to different rotating speeds so as to meet the requirements of adapting to different rotating speeds, and is novel in structural design.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a novel bearing with seat. Background technique [0002] As an important type of bearing structure, a bearing with a unit is widely used in mechanical equipment; wherein the bearing with a unit is fitted with a corresponding rotating shaft and the bearing with a unit is used to support the end of the rotating shaft. [0003] There are various forms of bearings with units in the prior art; however, the existing bearings with units can only be used in a specific speed range and have poor adaptability. Contents of the invention [0004] The object of the present invention is to provide a new type bearing with seat in view of the deficiencies in the prior art. The new type bearing with seat has a novel structural design and can effectively adjust the preload of the bearing to meet the requirements of adapting to different rotational speeds. [0005] In order to achieve the above ...
