Embodiment Construction
[0014] The embodiment of the present invention is as Figure 1-Figure 5 shown. Nylon was used as the material in the experiment. The outer diameter of the outer ring is 10mm, and the inner diameter of the outer ring is 8mm. Three grooves 6 and three curved cantilevers 4 are used. The depth of the groove 6 is 0.3mm. The α angle is 20°, and the β angle is 45°. The thickness of the compliant cantilever 4 is 0.5 mm, the radius of the large compliant joint 7 is 1.5 mm, and the radius of the small compliant joint 8 is 0.2 mm. In the unassembled state, the diameter d of the circle surrounded by the protrusion 3 is 4.5 mm. The inner ring 2 has an outer diameter of 6mm and an inner diameter of 4mm. 9Nm torque can be transmitted in the experiment.

An overrunning clutch with an outer ring and flexible cantilevers is characterized by consisting of an outer ring (1) and an inner ring (2). The outer circle of the inner ring (2) is smooth, a plurality of grooves (6) identical in shape are uniformly distributed on the inner side of the outer ring (1), curved flexible cantilevers (4) in the same number with the grooves (6) are machined between two grooves, each of the curved flexible cantilevers (4) is provided with an inward projection (3), the root of the outer side of the curved flexible cantilever (4) is a small flexible joint (8), and a large flexible joint (7) is arranged between the small flexible joint (8) and the projection (5). By the principle of the flexible cantilevers and the flexible joints, the overrunning clutch consists of two parts only, overcomes defects that the conventional overrunning clutch has parts in large quantity and not easy to be minimized or maintained, and accordingly has wide actual application prospect.
Description
technical field [0001] The invention relates to an overrunning clutch, belonging to the mechanical field. Background technique [0002] Overrunning clutches are used to transmit motion or power in one direction, and usually have a complex structure and need to be composed of many parts. The present invention utilizes the principles of compliant joints and compliant mechanical arms to design an overrunning clutch with only two parts, which is suitable for use in micro-mechanical transmission motion or low-power power. Its parts are suitable for injection molding with nylon or engineering plastics. Contents of the invention [0003] The purpose of the present invention is to design an overrunning clutch which is suitable for use in micro-miniature machines and is composed of only two parts, so as to overcome the disadvantage that the current overrunning clutch has many parts and is not suitable for miniaturization. [0004] figure 1 It is the assembly drawing of this kind...
