Bearing seat with adjustable axis

Abstract

The invention discloses an adjustable shaft center bearing seat, which belongs to the technical field of bearing installation. It includes a shaft seat; a mounting hole is opened in the center of the shaft seat, and a bearing is installed in the shaft seat mounting hole; the bearing includes a bearing inner ring, a bearing outer ring and rolling elements installed between the bearing inner ring and the bearing outer ring; There is a sinking groove on the outer ring surface of the bearing; a plurality of adjusting bolts are arranged around the shaft seat; the inner ends of the adjusting bolts are connected with a top plate through a spherical pair; the top plate fits on the outer ring of the bearing The arc in the groove. The invention has the advantages of simple structure, convenient adjustment, and good bearing stability; it can truly realize multi-directional and multi-range adjustment of the shaft center of the bearing. On the premise of ensuring the actual requirements, this structure can reduce the processing and assembly precision, thereby reducing the labor intensity of processing. The manufacturing and maintenance costs of the equipment are saved.

Description

technical field [0001] The invention relates to a bearing seat, in particular to an adjustable shaft center bearing seat. Background technique [0002] Bearing housings are one of the commonly used mechanical parts in the field of mechanical transmission, and bearing housings are involved almost everywhere with bearings. The bearing seat is used to install and fix the bearing, and can bear a certain supporting force. It can be divided into split bearing housings, sliding bearing housings, rolling bearing housings, bearing housings with flanges, outer spherical bearing housings, etc. Most of the existing bearing seats are fixed on the base with bolts and the threaded holes on the mounting seat. However, the distances between the threaded holes on some mounting seats are different. At this time, it is very troublesome. It is necessary to replace the bearing seat or install seat, increasing the cost. [0003] At present, the ordinary adjustable bearing seat has a single form...

AI Technical Summary

Problems solved by technology

Most of the existing bearing seats are fixed on the base with bolts and the threaded holes on the mounting seat. However, the distances between the threaded holes on some mounting seats are different. At this time, it is very troublesome. It is necessary to replace the bearing seat or install seat, increased cost

[0003] At present, the ordinary adjustable bearing seat has a single form and a small adjustable range. The precision requirements for the shaft installed on it are relatively high. At the same time, the precision requirements for the installation are also high, and the maintenance rate in the later period will also increase accordingly, which increases the production cost. , increasing the labor intensity of the operator and reducing production efficiency
