Embodiment Construction

[0007] As shown in Figure 1, the wedge block 3 of the present invention is arranged between the outer ring 1 and the inner ring 2 of the one-way clutch, and the contact surface with the inner ring 1 is A, and the lower end of the wedge block 3 and the one-way clutch The contact surface A adopts an involute 4 curved surface. In the figure, a is the center of the circle, point c coincides with point c', the involute 4 is centered at a, point c is fixed, and point c' passes through when it stretches outward A segment of trajectory BC in the route of . In this way, on the one hand, the curvature on the BC surface gradually increases from B to C, and on the other hand, the curvature center of each point on the BC surface also changes along the circular track of the base circle a, while maintaining the same circle center or curvature center of the upper surface EF The eccentric distance is basically unchanged, so as to ensure that the pressure angle during work is basically unchange...

Abstract

The present invention discloses a wedge-shaped block for one-way clutch. The invented wedge-shaped block is set between inner ring and outer ring of one-way clutch, the contact face of the described wedge-shaped block and inner ring and outer ring of said one-way clutch adopts involute curved face, so that when the clutch is worked, the curvature of said working face can be enlarged with the increment of load, the working face contact area also can be enlarged, therefore it can raise load-carrying capacity.

Description

technical field [0001] The invention relates to a wedge block for a one-way clutch, in particular to a wedge block for a one-way clutch with an involute curved surface design. Background technique [0002] In the prior art, commonly used one-way clutches are provided with a plurality of wedge-shaped blocks coaxially between their inner and outer rings, and the working surface in contact with the inner and outer rings of the one-way clutch adopts a simple eccentric cylindrical surface. Relatively simple, easy to manufacture and process, has been welcomed by people. However, the design pressure angle of this wedge block will be affected by wear, and the pressure angle will become larger or smaller. If it becomes smaller, it will affect the clutch performance; when it becomes larger, it will not function as a reverse load. Therefore, the commonly used wedge block wears a lot, has a short service life, weak bearing capacity and low reliability. Contents of the invention [0...
