Description

Gear one-way clutch Technical Field The utility model relates to a clutch, in particular to a gear one-way clutch, and belongs to the technical field of clutches. Background The gear unidirectional clutch is a special mechanical transmission device, the main function of which is to allow unidirectional power transmission and automatically cut off transmission in the reverse direction, and realizes a unidirectional working mode of 'driving-idling' through the internal structural design, and is widely applied to mechanical systems needing to prevent reverse or intermittent transmission. However, in most of the existing clutches, for example, in the gear one-way clutch disclosed in the publication No. CN201448387U, although the structure is compact, the operation is convenient, the clutch state can be switched by only changing the steering direction of the gear, but in the technical scheme and most of the existing gear one-way clutches, each part of the existing clutch needs to be subjected to multiple processes of turning, heat treatment, grinding and the like separately, so that the production period is prolonged, the assembly interference is easy to be caused by the accumulation of the dimensional tolerance of different parts, the coaxiality of the inner ring and the outer ring and the positioning precision of the retainer need to be ensured during the split assembly, the manual adjustment is time-consuming, and the qualification rate is low. Disclosure of utility model The technical scheme of the utility model aims at solving the technical problem that the prior art is too single, provides a solution which is obviously different from the prior art, and particularly aims at solving the defects in the prior art and providing a gear one-way clutch. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The gear one-way clutch comprises an outer gear ring, a mounting cavity, a retainer and an inner ring, wherein the mounting cavity is arranged at the axis of the bottom of the outer gear ring, the retainer is placed in the mounting cavity, the inner ring is placed in the retainer, and the outer gear ring, the retainer and the inner ring are all positioned on the same axis; The top of the retainer is provided with a notch in an inward concave manner, the notch is communicated with the front side and the rear side of the retainer, a steel ball is arranged in the notch of the retainer and is in rolling connection with the retainer, the steel ball is partially protruded out of the front side and the rear side of the retainer, and the protruded parts are respectively in rolling butt joint with the inner wall of the outer gear ring and the outer wall of the inner ring.
