Detailed Description
Embodiment one: referring to fig. 1-3, the invention discloses an anti-lock clutch mechanism, which comprises a transplanting power output shaft 1 and a swing rod shaft 6 with a swing rod 7; the transplanting power output shaft 1 is sequentially provided with a spring retainer ring 2, a pressure spring 3 and a cam shaft sleeve 4 from top to bottom, wherein the pressure spring 3 can be abutted against the spring retainer ring 2 and the cam shaft sleeve 4 and abutted against the cam shaft sleeve 4 to move up and down along the transplanting power output shaft 1; the end of the cam shaft sleeve 4 is connected with a driving gear 5 in a matched manner; the cam sleeve 4 is provided with a chute 41 with depth decreasing along the circumferential direction, and the swing rod 7 can be positioned in the chute 41 and is abutted against the cam sleeve 4.
The driving gear 5 is provided with a driving gear bulge 51, the cam shaft sleeve 4 is provided with a cam shaft sleeve bulge 43, and the driving gear bulge 51 and the cam shaft sleeve bulge 43 are mutually matched and connected for rapid and accurate occlusion of the driving gear 5 and the cam shaft sleeve 4. The drive gear boss 51 engages the cam sleeve boss 43 at an oblique angle.
The deepest end and the shallowest end of the depth of the chute 41 are provided with a stop block 42, the stop block 42 can block the swinging rod 7, and the swinging rod 7 is prevented from being separated from the chute 41 due to the rotation inertia of the cam shaft sleeve 4 when the swinging rod 7 moves along the chute 41.
Embodiment two: see fig. 1-3: an anti-lock clutch mechanism comprises a transplanting power output shaft 1 and a swing rod shaft 6 with a swing rod 7; the transplanting power output shaft 1 is sequentially provided with a spring retainer ring 2, a pressure spring 3 and a cam shaft sleeve 4 from top to bottom, wherein the pressure spring 3 can be abutted against the spring retainer ring 2 and the cam shaft sleeve 4 and abutted against the cam shaft sleeve 4 to move up and down along the transplanting power output shaft 1; the end of the cam shaft sleeve 4 is connected with a driving gear 5 in a matched manner; the cam sleeve 4 is provided with a chute 41 with depth decreasing along the circumferential direction, and the swing rod 7 can be positioned in the chute 41 and is abutted against the cam sleeve 4.
The driving gear 5 is provided with a driving gear bulge 51, the cam shaft sleeve 4 is provided with a cam shaft sleeve bulge 43, and the driving gear bulge 51 and the cam shaft sleeve bulge 43 are mutually matched and connected for rapid and accurate occlusion of the driving gear 5 and the cam shaft sleeve 4. The drive gear boss 51 engages the cam sleeve boss 43 at an oblique angle.
The outer peripheral surface of the transplanting power output shaft 1 is provided with a spline 11, and the cam shaft sleeve 4 is meshed with the spline 11 and can move up and down along the spline 11.
Referring to fig. 1-3, the working process of the invention is as follows: when the cam sleeve 4 and the driving gear 5 are in a meshed state, and an external force acts on the swing rod shaft 6, the swing rod 7 swings to be attached in the chute 41 of the cam sleeve 4, and the cam sleeve 4 and the driving gear 5 rotate together in a counterclockwise direction; at this time, the chute 41 is turned from deep to shallow, the swing rod 7 gradually separates the cam sleeve 4 from the driving gear 5, and the separation state of the clutch is completed, at this time, the transplanting power of the gearbox is stopped by the separation of the driving gear 5 and the cam sleeve 4, and the power output for completing the transplanting operation is stopped.
When an external force acts on the swing link shaft 6 so that the swing link 7 swings to be separated from the cam sleeve 4. The upper end of the pressure spring 3 is limited on the spring baffle plate 2, the other end of the pressure spring outputs pressure to enable the cam shaft sleeve to downwards until the cam shaft sleeve is completely meshed with the driving gear 5, so that the clutch is in a meshed state, at the moment, the transplanting power of the gearbox is transmitted to the cam shaft sleeve 4 through the driving gear 5, and then the transplanting power is transmitted to a transplanting power output shaft through spline connection by the cam shaft sleeve 4, so that the power output of the transplanting operation is completed.
