Combined bearing of paper machine

Abstract

The invention discloses a combined bearing of a paper machine. The combined bearing is characterized in that the combined bearing comprises a three-ring bearing, a sliding bearing is arranged between a middle ring and an outer ring, rollers are arranged between the middle ring and an inner ring and form a rolling bearing, the sliding bearing bears large radial load and has the aligning effects, and the rolling bearing produces the rotation effects in main bearing operation. Through the three-ring bearing, multiple sets of existing bearings are replaced only by one bearing, problems of aligning and large radial load are solved, a space is effectively saved and a raw material cost and a labor cost are reduced. The sliding bearing is arranged between the middle ring and the outer ring and the rollers are arranged between the middle ring and the inner ring and form the rolling bearing, the sliding bearing bears large radial load and has the aligning effects, and the rolling bearing produces the rotation effects in main bearing operation. The combined bearing has very high operation reliability, can be installed easily and is a high-quality high-precision bearing.

Description

technical field [0001] The invention relates to the technical field of bearings. Background technique [0002] The bearings used in paper machines in the prior art are all self-aligning roller bearings and cylindrical roller bearings, and self-aligning roller bearings occupy a dominant position in the papermaking industry. in the attached system, [0003] Such as figure 1 The self-aligning cylindrical roller bearing shown includes an outer ring 01, an inner ring 02, cylindrical rollers 04 and a cage 06. Contents of the invention [0004] The present invention aims to provide a bearing specially used on a paper machine. [0005] In order to achieve the above object, the present invention provides a composite bearing for a paper machine, which is characterized in that it includes a three-ring bearing, the sliding bearing is between the middle ring and the outer ring, and the roller between the middle ring and the inner ring is a rolling bearing, and the sliding bearing pa...

AI Technical Summary

Problems solved by technology

[0006] The self-aligning cylindrical roller bearing, that is, the three-ring bearing, solves the problem of using multiple sets of bearings in the past and now only needs one set of bearings, which not only solves the problem of self-alignment but also solves the problem of bearing large radial loads, saving effective space, reducing the cost of raw materials and labor costs, the middle ring and the outer ring are sliding bearings, and the rollers between the middle ring and the inner ring are rolling bearings. The rolling bearing part plays the role of rotation during the main operation of the bearing
