Embodiment Construction

[0034] The invention will be further illustrated by the following examples.

[0035] This embodiment consists of an outer ring (1), elastic cylindrical rollers (2), a slider (3) and an inner ring (4). Elastic cylindrical rollers (2) and sliders (3) are located in the chute between the outer ring (1) and inner ring (4); the number of elastic cylindrical rollers and sliders is equal, and they are separated from each other; The diameter of the roller is larger than the thickness of the slider in the radial direction of the bearing, and the axial length of the elastic cylindrical roller is smaller than the length of the slider in the axial direction of the bearing; the elastic cylindrical roller has a certain pre-compression in the diameter direction, and the slider and the inner ring There is a slight gap between the outer ring and the elastic cylindrical roller and the slider to maintain contact. The rolling bearing is lubricated by circulating oil, and the oil supplied from th...

Abstract

The invention provides an oil lubricating roll-slide bearing with an elastic roller. The roll-slide bearing consists of an outer ring (1), elastic cylindrical rollers (2), slide blocks (3) and an inner ring (4), wherein the elastic cylindrical roller (2) and the slide block (3) are positioned in a chute between the outer ring (1) and the inner ring (4); the number of the elastic cylindrical rollers (2) equals to that of the slide blocks (3), and the elastic cylindrical rollers (2) and the slide blocks (3) are distributed at intervals; the diameter of the elastic cylindrical roller (2) is morethan the thickness of the slide block (3) in the radial direction of the bearing, and the axial length of the elastic cylindrical roller (2) is less than the length of the slide block (3) in the axial direction of the bearing; the elastic cylindrical roller has a certain pre-compression amount in the diameter direction, trace clearances are reserved between the slide blocks (3) and the inner ring(1) and between the slide blocks (3) and the outer ring (4), and the elastic cylindrical rollers (2) are kept to be contacted with the slide blocks (3). The oil lubricating roll-slide bearing is usedfor reducing the applied stress on the inner and outer rings and the elastic cylindrical roller, has the characteristics of storing and releasing energy and maintaining rolling, and has small abrasion and long service life compared with those of a roll-slide bearing with a corresponding size.

Description

technical field [0001] The invention belongs to the field of mechanical engineering. Background technique [0002] The invention is suitable for rotating machines and plays the role of supporting shafts, and is especially suitable for supporting the shafts of rotating machines in heavy-load impact environments. At present, rolling bearings and dynamic pressure sliding bearings are mainly used to support the shaft of rotating machinery under heavy load impact environment. The advantages of rolling bearings are small starting friction resistance, low friction coefficient and convenient maintenance. The advantage of the bearing is that it has a strong ability to withstand impact loads and a simple structure. The biggest disadvantage is that the frictional resistance is large at start-up and low speed. The bearing that is more suitable for supporting heavy loads is the rolling-sliding composite bearing invented by Mr. Tian Hongping, but this rolling-sliding composite bearing ha...
