There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as the gearbox shift gear.
[0003] At the same time, the application number is 202222172882.2. A manual clutch structure includes a clutch seat, an inner spline sleeve and an outer spline sleeve. The inner spline sleeve is used for sliding sleeve connection on the outer side of the first rotating shaft, and the inner spline sleeve and the first rotating shaft are circumferentially positioned by a key connection. The outer spline sleeve is used for fixed sleeve connection on the outer side of the second rotating shaft. A deep groove ball bearing is sleeved on the outer side of the inner spline sleeve. A paddle shaft is rotatably connected to the clutch seat, a paddle plate is fixed on the paddle shaft, and a clamp is rotatably connected to the paddle plate. The two clamping arms of the clamp are blocked on both sides of the outer ring of the deep groove ball bearing.
