Problems solved by technology

The non-contact overrunning clutch overcomes the disadvantages of the contact overrunning clutch and is an important branch of the overrunning clutch. Among them, the wedge type non-contact overrunning clutch has a good development prospect because of its simple structure, reliable locking and easy separation. There are also some defects-in the overrunning stroke, the wedge tilts under centrifugal action to maintain the distance from the outer ring and the inner ring, which can only be achieved under a certain speed condition, and the scope of use is greatly limited; the wedge The contact form with the outer ring and the inner ring is line contact, the transmission area is small, and the transmission surface is easily damaged due to too much pressure

Embodiment Construction

[0018] refer to figure 1 and figure 2 , the present invention has a middle ring 28, which can rotate coaxially with the outer ring 1, the clutch seat, the inner ring 9 or the central shaft 10 in the radial direction; Also one side of the middle ring 28 is rotationally connected with the outer ring 1, the clutch seat, the inner ring 9 or the central shaft 10, and the two connection points are at different radial positions, so that the middle ring 28 and the outer ring 28 linked with it through the double block 3 When an angular displacement occurs between the ring 1, the clutch seat, the inner ring 9 or the central shaft 10, it can drive the double block 3 to tilt in the circumferential direction; The change of the included angle changes in a negative correlation. When the included angle was the largest, the double joint block 3 could not contact or have no pressure contact with the outer ring 1, the clutch seat, the inner ring 9 or the central shaft 10 on the other side of t...

Abstract

The invention discloses a duplex block overrunning clutch. The duplex block overrunning clutch is a non-contact overrunning clutch, a duplex block (3) is used as a locking element, the duplex block (3) does not need to be kept in contact with a locked object in the overrunning stroke, abrasion and energy consumption can be reduced, and due to the fact that a roller is not needed for triggering thelocking action, a magnetic suspension structure can be adopted between rotating pieces to further reduce motion resistance and reduce vibration. The locking and separating actions of the duplex block(3) are directly associated with the relative movement direction of a locked object and are not limited by the rotating speed condition of the duplex block. The duplex block (3) can be in friction transmission with the locked object in a linear contact manner and can also be matched with a surface contact type locking element or a rigid meshing element to greatly improve the bearing capacity. Inaddition, the functions of forward locking and reverse separation, forward separation and reverse locking, bidirectional locking and the like are achieved through an inclination adjusting mechanism.

Description

technical field [0001] The invention provides an overrunning clutch. Background technique [0002] The current overrunning clutches are mainly contact roller or sprag overrunning clutches. The rollers or sprags must keep in contact with the outer ring or inner ring during the overrunning stroke, which not only reduces the transmission efficiency due to heat and energy consumption, but also seriously shortens the service life due to wear. The non-contact overrunning clutch overcomes the disadvantages of the contact overrunning clutch and is an important branch of the overrunning clutch. Among them, the wedge type non-contact overrunning clutch has a good development prospect because of its simple structure, reliable locking and easy separation. There are also some defects-in the overrunning stroke, the wedge tilts under centrifugal action to maintain the distance from the outer ring and the inner ring, which can only be achieved under a certain speed condition, and the scope ...
