Novel sliding block type bidirectional overrunning clutch

Abstract

The invention discloses a novel sliding block type bidirectional overrunning clutch. The novel sliding block type bi-directional overrunning clutch comprises an outer ring and sliding blocks. An inner ring support and a driving shifting fork are arranged inside the outer ring and fixed through check rings, close to the two ends, inside the outer ring. The inner ring support is provided with semi-circular groove rolling channels. The working face of each sliding block is arranged in the corresponding semi-circular groove rolling channel and is in contact with the corresponding semi-circular groove rolling channel. Each pair of semi-circular groove rolling channels and the pairs of sliding blocks are configured in opposite directions. The sliding blocks are in series connection through a spring to form an annular shape, and the sliding blocks are arranged in an annular space between an outer ring inner hole rolling channel and the inner ring support. The driving shifting fork is provided with shifting fork protruding claws. Each shifting fork protruding claw is inserted into a space between the corresponding sliding blocks which are arranged in opposite directions. The clutch has the beneficial effects of being reliable in bidirectional self-locking, precise in positioning and stable in operation; no impact or noise is generated in the releasing process; and the clutch is high in transmission efficiency and long in service life. In mechanical transmission, the clutch can be used for preventing reverse rotation bidirectionally; bidirectional rotation of a driving end can drive bidirectional rotation of a driven end; and the purpose of precise positioning or torque transmission or overrunning is achieved.

Description

technical field [0001] The invention relates to the technical field of an overrunning clutch, a general component of mechanical transmission, in particular to a novel slider-type two-way overrunning clutch. Background technique [0002] At present, two-way overrunning clutches are used in machine tools, printing and packaging machinery, petrochemical machinery, light industrial machinery, food machinery, weapons and other mechanical transmissions, especially when used in conjunction with ball screws or reducers, mainly to prevent mechanism reversal, precise positioning, and transfer rotation. moment or beyond. With the innovation of science and technology and the development of modern technology, the application field of two-way overrunning clutch is constantly expanding, and the demand is increasing. For example, when there is two-way torque in the active transmission system, it can transmit it to the driven transmission system. On the contrary, Regardless of whether the d...
