Embodiment Construction
[0030] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help the understanding of the present invention, but do not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] like figure 1 and figure 2 As shown, a novel slider type two-way overrunning clutch of the present invention includes an outer ring 1 and a slider 9. The outer ring 1 is cylindrical and can be connected to the transmission mechanism by bolts or other means; In connection mode, a plurality of evenly distributed bolt holes are provided at both ends of the outer ring 1 .
[0032] The inside of the outer ring 1 is provided with an inner ring support 3 and an ac...

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 overrunning clutches for general parts of mechanical transmission, in particular to a novel slider type two-way overrunning clutch. Background technique [0002] At present, the two-way overrunning clutch is used in machine tools, printing machinery, petrochemical machinery, light industrial machinery, food machinery, weapons and other mechanical transmissions, especially with ball screws or reducers. Moment or beyond. With scientific and technological innovation and the development of modern technology, the application field of the two-way overrunning clutch is constantly expanding, and the demand is increasing. For example, when there is two-way torque on the active transmission system, it can be transmitted to the driven transmission system. When the driven transmission system is subjected to clockwise or counterclockwise external torque, the direction of the active transmission system cannot be rever...
