Abstract

The invention relates to a bearing seat capable of adjusting gear axial position, comprising a base and two support plates vertically arranged on the base. The two support plates are provided with two round holes facing each other. A bearing sleeve of clearance fit is in the round hole. Two ends of the bearing sleeve extend out of the round hole and nuts are provided. The bearing sleeve has a step-type wall body and the step surface abuts against an end surface of the bearing. Shaft movement can be realized only by adjusting nuts on two sides of the bearing sleeve. Therefore, the bearing seat of the invention can be used for substantially conveniently adjusting the shaft and adjusting the axial position of the gear on the shaft.

Description

A kind of bearing support from gear shaft to the position that adjust
Technical field
The present invention relates to a kind of component of machine, especially a kind of bearing support.
Background technique
As everyone knows, in the installation and using process of gear-box and gearbox, need adjust, reach good engagement effect to guarantee gear, and make bearing keep normal play axle and the axial position that is fixed on component such as gear on the axle, bearing.Particularly, higher to the requirement of axial position adjustment for bevel gear drive.At present, the overwhelming majority adopts the method that installs spacer additional or polished in spacer end face scene to realize.But, install spacer additional and only be fit to install additional, adjust through the bearing (ball) cover inboard being installed in casing outside, when Bearing Installation during, be difficult to realization at box house.And to the on-the-spot polishing of spacer end face, adjustment amount is restive, the installation adjustment time is long, and adjustment is relatively more difficult more next time after the once mounting.
Summary of the invention
The technical problem that the present invention will solve provides a kind of bearing support of convenient adjustment gear axial position.
In order to solve the problems of the technologies described above, the present invention includes base, be vertically installed with first dunnage and second dunnage at interval on the base, on two dunnages the circular hole that is oppositely arranged is arranged.Be provided with columnar clutch shaft bearing cover in the first dunnage circular hole, clutch shaft bearing cover outer surface and circular-hole internal-wall Spielpassung, circular hole is stretched out at clutch shaft bearing cover two ends; The termination outer surface is provided with outside thread; Clutch shaft bearing cover two ends also are provided with first nut and second nut with termination outside thread coupling, and clutch shaft bearing cover wall body is a stepped shape, and its inner chamber forms two cavitys that vary in size; Between two cavitys first terrace is arranged, big cavity inner surface and clutch shaft bearing Spielpassung; Be provided with columnar second bearing housing in the second dunnage circular hole, the second bearing housing outer surface and circular-hole internal-wall Spielpassung, circular hole is stretched out at the second bearing housing two ends; The termination outer surface is provided with outside thread; The second bearing housing two ends also are provided with the 3rd nut and the 4th nut with termination outside thread coupling, and the second bearing housing wall body is a stepped shape, and its inner chamber forms two cavitys that vary in size; Between two cavitys second terrace is arranged, big cavity inner surface cooperates with second bearing play; First terrace is relative with second terrace, and is inconsistent with the end face of the end face of clutch shaft bearing and second bearing respectively.
In use loosening in order to prevent nut, be provided with first lock washer between first nut and second nut and first dunnage, be equipped with second lock washer between the 3rd nut and the 4th nut and second dunnage.
Description of drawings
Accompanying drawing is an axial sectional view of the present invention.
Embodiment
Shown in accompanying drawing, the present invention includes base 1, be vertically installed with first dunnage 2 and second dunnage 3 at interval on the base 1, the base plate of base 1 gear-box capable of using, the side plate of first dunnage 2 and second dunnage, 3 gear-boxes capable of using is processed.On two dunnages the circular hole that is oppositely arranged is arranged, be provided with columnar clutch shaft bearing cover 21 in the first dunnage circular hole, clutch shaft bearing overlaps 21 outer surfaces and circular-hole internal-wall Spielpassung, can in circular hole, move along axial direction.Clutch shaft bearing overlaps 21 two ends and stretches out circular hole, and the termination outer surface is provided with outside thread, and clutch shaft bearing overlaps 21 two ends and also is provided with first nut 22 and second nut 23 that matees with the termination outside thread.It is stepped shape that clutch shaft bearing overlaps 21 wall bodies, and its inner chamber forms two cavitys that vary in size, and first terrace 24 is arranged between two cavitys, big cavity inner surface and clutch shaft bearing 4 Spielpassung; Be provided with columnar second bearing housing 31 in second dunnage, 3 circular holes; Second bearing housing, 31 outer surfaces and circular-hole internal-wall Spielpassung; Circular hole is stretched out at second bearing housing, 31 two ends; The termination outer surface is provided with outside thread, and second bearing housing, 31 two ends also are provided with the 3rd nut 32 and the 4th nut 33 with termination outside thread coupling.Second bearing housing, 31 wall bodies are similarly stepped shape, and its inner chamber forms two cavitys that vary in size, and second terrace 34 is arranged between two cavitys, big cavity inner surface and second bearing, 5 Spielpassung; First terrace 24 is relative with second terrace 34, and is inconsistent with the end face of the end face of clutch shaft bearing 4 and second bearing 5 respectively.
In use loosening in order to prevent nut, be provided with between first nut 22 and second nut 23 and first dunnage 2 between first lock washer, 61, the three nuts 32 and the 4th nut 33 and second dunnage 3 and be provided with second lock washer 62.
The method for using of this bearing support is: when needs are adjusted axial the 4th nut 33 directions; Elder generation's inverse clock is unscrewed first nut 22 and the 3rd nut 32; Clockwise is tightened second nut 23 then, and clutch shaft bearing cover 21 moves to the 4th nut 33 directions under the extruding force of second nut, 23 internal threads promotes, and first terrace, 24 promotion clutch shaft bearings 4 move with axial the 4th nut 33 directions simultaneously; After adjusting to the right place, tighten first nut 22, the 3rd nut 33 and the 4th nut 34.
When needs are adjusted axial first nut, 21 directions; Elder generation's inverse clock is unscrewed the 4th nut 33 and the 2nd nut 23; Clockwise is tightened the 3rd nut 32, the second bearing housings 31 and is promoted to move to first nut, 22 directions down in the extruding force of the 3rd nut 32 internal threads then, and second terrace 34 promotes second bearing 5 and axial first nut, 22 directions move simultaneously; After adjusting to the right place, tighten the 4th nut 33, second nut 23 and first nut 22.
