Mechanical bearing block having high stability

Abstract

The invention discloses a mechanical bearing block having the high stability. The mechanical bearing block comprises a lower seat and an upper seat; lower-position mounting seats are formed on the twosides of the lower seat through integral casting; upper-position mounting seats are integrally formed on the two sides of the upper seat; arc-shaped grooves are formed in the opposite surfaces of thelower seat and the upper seat; a ball bearing is fixedly mounted in the arc-shaped grooves of the lower seat and the upper seat and comprises a bearing outer ring, a bearing inner ring and a ball combination; a transmission shaft is fixedly mounted in the bearing inner ring; fixing bolt holes are formed in seat bodies of the lower-position mounting seats; moving grooves are formed in the upper-position mounting seats, moving blocks are arranged in the upper-position moving grooves, supporting springs are arranged on the lower surfaces of the moving blocks, first limiting bulges are formed onthe upper surfaces of the moving blocks, and second limiting bulges are formed on the lower surfaces of nuts of fixing bolts, so that under the mutual clamping action of the first limiting bulges andthe second limiting bulges, the loosening phenomena of the fixing bolts are avoided effectively.

Description

technical field [0001] The invention relates to the related technical field of bearing seats, in particular to a mechanical bearing seat with high stability. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Its essence is to bear radial loads. There are many types of bearings and are widely used in various mechanical structures. Bearings In order to ensure its stability during use, most of them need to be used in conjunction with the bearing seat. The bearing seat can accept comprehensive loads and special large and extra-large bearing tools. It has the characteristics of compact structure, sensitive rotation, and convenient maintenance of the device. [0003] In the prior art, the bearing seat is composed of two parts, the lower seat and the upper seat, and the lower seat and t...

Problems solved by technology

[0003] In the prior art, the bearing seat is composed of two parts, the lower seat and the upper seat, and the lower seat and the upper seat are fixedly connected by bolts, but ordinary bolts will exist under the influence of mechanical vibration generated by mechanical operation. The hidden danger of loosening, and in order to prevent the bolts from loosening, the staff usually use a wrench with a large torque to tighten the bolts, but the effect is not obvious, and the over-tightened bolts will still exist in the later disassembly and maintenance process Difficult to remove bolts
