Abstract
Description
Technical Field
[0001] This utility model relates to the field of meshing teeth for clutch drive shafts, specifically to a passive meshing tooth structure for a mechanical clutch drive shaft. Background Technology
[0002] Currently, clutch drive shafts are divided into various types, including mechanical, electromagnetic, hydraulic, and pneumatic. Among them, mechanical clutch devices include dog clutch type and friction type. Dog clutch devices can strictly ensure the synchronization of two drive shafts, but a large impact force is generated during the meshing process of dog clutch devices, resulting in a short service life. Therefore, this utility model proposes a passive meshing tooth structure for mechanical clutch drive shafts. Utility Model Content
[0003] In order to overcome the defects in the prior art, this utility model provides a passive meshing tooth structure for a mechanical clutch transmission shaft. By designing and adjusting the shape and structure of the boss that plays a meshing role, the impact force during the meshing process of the boss can be reduced, thereby extending the service life.
[0004] Technical solution
[0005] A passive engagement gear structure for a mechanical clutch drive shaft includes a body capable of rotating relative to the drive shaft. The body is further provided with a plurality of bosses, each boss including a first inclined surface, a second inclined surface, and a third inclined surface. The angle between the intersection line of the first inclined surface and the second inclined surface and the intersection line of the second inclined surface and the third inclined surface is 0-25°. At least one inclined surface exists on each boss.
[0006] Furthermore, the annular array of protrusions is disposed on one side plane of the body.
[0007] Furthermore, the first inclined plane and the third inclined plane are twisted curved surfaces.
[0008] Furthermore, a shaft mounting hole extends through the middle of the main body.
[0009] Furthermore, a worm gear meshing structure is also provided on the outer annular surface of the body.
[0010] Furthermore, several holes are arranged in a ring array on both sides of the main body outside the shaft mounting hole.
[0011] Furthermore, the sides of the boss that are close to and far from the shaft mounting hole are arc surfaces.
[0012] Beneficial effects
[0013] Compared with the prior art, this utility model has the following advantages: by designing and adjusting the shape and structure of the boss that plays a role in meshing, the impact force during the meshing process of the boss can be reduced, thereby extending the service life.
