Tension bearing

Abstract

The invention discloses a tension bearing, and belongs to the technical field of bearings. The tension bearing comprises first inner rings, second inner rings, balls, retainers, an outer ring, tensionblocks and bolts, wherein two first inner rings, two second inner rings, two balls and two retainers are provided, and are symmetrically arranged on two sides of the outer ring in an axial direction;the first inner rings, the second inner rings and the outer ring are coaxially arranged; the second inner rings are arranged outside the first inner rings in a sleeving manner; the first inner ringsand the second inner rings are in clearance arrangement to form inner oil storage cavities; the tension blocks are mounted on the outer sides of the first inner rings; the tension blocks are in hollowround table shapes; horn-shaped openings are formed in the outer sides of the first inner rings, and the inner walls of the first inner rings are attached to the outer walls of the tension blocks; the tension blocks comprise upper tension half blocks and lower tension half blocks which are inserted mutually. The two tension blocks clamp the first inner rings, so that the bearing is fixedly mounted on rotating shafts with different diameters to achieve a tension effect.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a tension bearing. Background technique [0002] In conveyors and other equipment, bearings are extremely important components, and the normal operation of the machine needs to be driven by sprockets. [0003] Due to the higher and higher requirements for the conveying capacity of conveyors and other equipment, the requirements for the mechanical properties of bearings are also getting higher and higher. [0004] Tension bearings are now commonly used bearings for high-intensity operations. They are generally composed of inner tension tail shafts and tail wheels fixed through bearing seats. However, such a structure will cause a lot of stress when the bearings are running. Moreover, Such a connection is relatively loose, and the vibration during operation is also relatively large. Contents of the invention [0005] The object of the present invention is to provid...

[0004] Tension bearings are now commonly used bearings for high-intensity operations. They are generally composed of inner tension tail shafts and tail wheels fixed through bearing seats. However, such a structure will cause a lot of stress when the bearings are running. Moreover, This kind of connection is relatively loose, and the vibration during operation is also relatively large.
