An automatic jaw clutch

Abstract

The invention relates to an automatic tooth-embedded clutch. The automatic tooth-embedded clutch comprises a first half clutch body, a second half clutch body, first bearings, second bearings, a spline sleeve, a spline drum and a wheel shaft. The wheel shaft is a long strip-shaped cylindrical shaft. The two ends of the spline drum are both rotatably connected with the wheel shaft through the first bearings. Driven teeth are arranged at one end of the first half clutch body, and the other end of the first half clutch body is fixedly connected with the spline drum. The two ends of the spline sleeve are both rotatably connected with the wheel shaft through the second bearings. The spline sleeve is close to the first half clutch body. A key groove matched with a chain wheel is formed in the outer side of the spline sleeve. The second spline sleeve is sleeved with the second half clutch body. Driving teeth are arranged at the end, close to the first half clutch body, of the second half clutch body. The second half clutch body can be driven by the spline sleeve to rotate, and the second half clutch body can move on the spline sleeve to be close to or away from the first half clutch body. According to the technical scheme, on the basis that automatic separation and combination of the clutch can be achieved, the wheel shaft is fixedly arranged, friction between the wheel shaft and rotary components is reduced, and the fixing way of the wheel shaft is simplified.

Description

technical field [0001] The invention relates to the technical field of a clutch, in particular to an automatic jaw clutch. Background technique [0002] Such as figure 1 As shown, the existing main shaft 1' with its own jaw clutch can rotate under the drive of the sprocket flange 3', and the sprocket flange 3' is fixedly connected to the main shaft 1' through the flange nut 6'. The hub ratchet 4' is fixedly connected with the hub 2', the power ratchet 5' cooperates with the main shaft 1' through a helical spline, and the ratchet stop ring 7' blocks and limits the power ratchet 5'. During the specific clutch process, the sprocket flange 3' drives the main shaft 1' to rotate through the spline, and the rotating spline on the main shaft 1' drives the power ratchet 5' to rotate. When the rotation speed of the power ratchet 5' is lower than that of the main shaft 1' When the rotational speed of the main shaft 1' is guided by the rotating spline, the power ratchet 5' closes with...

AI Technical Summary

Problems solved by technology

[0003] With this structure, the fixing method of the main shaft is complicated, and the friction between the main shaft and the sprocket flange and the power ratchet is relatively large

In the long-term use process, the wear and tear between the parts is relatively serious, the service life is too short, and the parts need to be replaced frequently, resulting in an increase in the cost of use
