Elastic radial sliding bearing with adjustable gaps

Abstract

The invention relates to an elastic radial sliding bearing with adjustable gaps. The left end and the right end of the elastic bearing are each provided with eight gaps; the outer circle of the elastic bearing is provided with two outer conical surfaces, the inner holes of a bearing outer sleeve and a bearing inner sleeve are both designed as inner conical surfaces, the bearing outer sleeve and the bearing inner sleeve are respectively matched with the outer conical surfaces of the elastic bearing through the inner conical surfaces, and the bearing outer sleeve and the bearing inner sleeve arein threaded connection; and if the clearance between the bearing and a rotor is too large in the assembling, trial running, overhauling and using processes of equipment, the bearing inner sleeve canbe screwed at any time according to the technical requirements, and the clearance between the inner hole of the bearing and the rotor can be adjusted. The elastic radial sliding bearing with the adjustable gaps avoids the situation that due to the too big clearance between the bearing and the rotor (transmission shaft) caused by design, use, manufacturing and the like, the bearing needs to be re-manufactured, and has the advantages of reducing the cost and improving the efficiency. The elastic scaling gaps are large, and serialization and standardization of the sliding bearing can be realized.Reasonable clearance adjustment can best control the temperature and vibration during operation of the bearing and the rotor.

Description

technical field [0001] The invention belongs to a sliding bearing, in particular to an elastic radial sliding bearing with adjustable clearance. Background technique [0002] The main function of the radial sliding bearing in the mechanical transmission process is to support the load of the rotor (transmission shaft) and ensure the stable operation of the rotor. The accuracy of the bearing and the proper clearance between the inner diameter of the bearing and the rotor are the key factors for the stable operation of the rotor. At present, there are mainly three situations about the radial clearance of sliding bearings. In the first case, the designer calculates and designs the radial clearance of the bearing based on experience and formula software. It was found that the inner hole of the bearing became larger due to wear and tear, and the bearing needed to be remade; in the third case, when the inner hole of the bearing was larger than the design requirements due to worker...

Problems solved by technology

[0003] In order to overcome the above-mentioned problems in the prior art, the object of the present invention is to provide an elastic radial sliding bearing with adjustable clearance. The gap between the bearing and the rotor (drive shaft) is too large due to other reasons, and the gap between the inner hole of the bearing and the rotor can be adjusted at any time during assembly, debugging and use, especially during the test run to make the rotor run in a In the ideal index state, it is one of the powerful guarantee factors for the stable operation of the rotor
