Abstract
The utility model belongs to the technical field of conveying equipment, and particularly relates to an endless opening roller in interference fit. The endless opening roller in interference fit comprises a pipe, a shaft and a bearing block; the bearing block is pressed into the pipe by interference fit, then the contact part of the front end face of an excircle of the bearing block and the inner wall surface of the pipe is welded, and a labyrinth sealing element extends into an end cover, so that the production cost is reduced, and the service life of the roller is improved.
Description
Technical field
The utility model belongs to the load transfer device technical field, is specifically related to a kind of interference fit without the seam carrying roller.
Background technology
The performance figure of carrying roller and build guality directly affect overall performance and the availability of belt conveyer, existing carrying roller is made at the special plane manufacturing line, but the special plane apparatus for production line is along with the increase of period of service, special plane apparatus for production line performance figure descend gradually, there is overproof problem in the cylindrical radial runout and reprocesses to make carrying roller assemble afterwards, wherein managing seam processing is the critical process that carrying roller is produced, and the processing of pipe seam has reduced the accuracy of manufacture of carrying roller owing to affected by operator's manual operations.
Summary of the invention
For the problem of above-mentioned existence, the utility model provides a kind of interference fit without the seam carrying roller.
Interference fit of the present utility model is without the seam carrying roller, comprise pipe, axle and bearing seat, main points are that bearing seat is pressed in the pipe by interference fit, then bearing seat cylindrical front end face and the contacted position of inside pipe wall face are welded, labyrinth seal is extended in the end cap.
The magnitude of interference of described bearing seat cylindrical and inside pipe wall is 0.5 millimeter～0.6 millimeter.
The beneficial effects of the utility model are: technique is simple, has improved work efficiency, has reduced productive costs, has improved the service life of carrying roller.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1 pipe, 2 axles, 3 bearing seats, 4 bearings, 5 labyrinth seals, 6 end caps.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Example 1. interference fit of the present utility model are without the seam carrying roller, comprise pipe 1, axle 2 and bearing seat 3, bearing seat 3 is pressed in the pipe 1 by interference fit, then bearing seat 3 cylindrical front end faces and the contacted position of pipe 1 internal face are welded, labyrinth seal 5 is extended in the end cap 6, and bearing seat 3 cylindricals are 0.5 millimeter with the magnitude of interference of pipe 1 inwall.
During assembling, on common carrying roller pressing machine, in the cold pressing mode bearing seat 3 is pressed in the pipe 1, then bearing seat 3 and the contacted position of pipe 1 internal face are welded, then pack into axle 2 and bearing 4 extend to labyrinth seal 5 in the end cap 6 simultaneously, and labyrinth seal 5 and end cap 6 are become one, reduce axial dimension, reduce simultaneously the degree of depth and the punching press number of times of bearing seat 3, reduced productive costs, improved the service life of carrying roller.
Claims (2)
1. an interference fit comprises pipe without the seam carrying roller, and axle and bearing seat is characterized in that bearing seat is pressed in the pipe by interference fit, then bearing seat cylindrical front end face and the contacted position of inside pipe wall face are welded, and labyrinth seal is extended in the end cap.
2. a kind of interference fit as claimed in claim 1 is without the seam carrying roller, and the magnitude of interference that it is characterized in that bearing seat cylindrical and inside pipe wall is 0.5 millimeter～0.6 millimeter.
