Self-resetting double-sealing reverse locking composite bearing

Abstract

The invention relates to a self-resetting double-sealing reverse locking composite bearing. An inner ball groove with an arc-shaped cross section is formed in the first end of the surface of the outer circumference of an inner ring, and a smooth surface is arranged at the second end of the surface of the outer circumference of the inner ring. An outer ball groove with an arc-shaped cross section is formed in the surface of the inner circumference of a first outer ring. A plurality of sets of curve faces connected end to end are arranged on the surface of the inner circumference of a second outer ring, one end of each curve face is an arc section, the other end of each curve face is a linear section, and the arc sections and the linear sections are in smooth transition connection. A ribbon retainer is arranged between the first end of the inner ring and the first outer ring, and balls are arranged in the ball bags of the ribbon retainer; a self-resetting retainer is arranged between the second end of the inner ring and the second outer ring, rolling columns are arranged in the mounting window holes of the self-resetting retainer, cantilever limit blocks are arranged on the mounting window hoes, one end of each cantilever limit block is fixed to the self-resetting retainer, and a bent portion capable of being elastically bent towards one sides of the rolling columns is arranged at the other end of each cantilever limit block. The self-resetting double-sealing reverse locking composite bearing is simple in structure, ingenious in design and convenient and reliable to assemble.

Description

technical field [0001] The invention relates to a reverse stop bearing for a clutch, in particular to a self-resetting double-seal reverse stop composite bearing, which belongs to the technical field of reverse stop bearings. Background technique [0002] The existing roller type reverse stop bearing has been used in switching mechanisms for overrunning or transmitting torque, preventing reverse rotation, precise positioning, and single-machine double-speed operation. Commonly used in various machine tools, packaging machinery, printing machinery, light industrial machinery, petrochemical machinery, metallurgical machinery, mining machinery, reducers, belt conveyors, rotary conveyors, bucket elevators, power generation equipment, automobiles, ships, airplanes , bombers and light howitzers and other industries. Especially in the clutch industry, it is widely used, and it mainly realizes the work of the clutch through the operation of the roller type reverse stop bearing. ...

AI Technical Summary

Problems solved by technology

At present, the new type of clutch mainly adopts the form of simultaneous assembly of ball bearings and reverse stop bearings to realize its functional requirements. The simultaneous assembly of the two bearings is costly and inconvenient to install. Moreover, there is mutual operation interference, which leads to obvious hysteresis and causes gaps between components. The impact of each other, unable to withstand a large stop torque, resulting in early failure of the bearing

At the same time, due to the compact structure of the new clutch, when the bearing is pressed into the clutch, the first set of bearings will be crushed when the second set of bearings are pressed, resulting in loud noise in the operation of the bearings.
