Detailed Description
The technical scheme of the invention is further explained in detail by combining the attached drawings:
the invention provides a movable coupling convenient to sleeve, which comprises a sleeve 1 and a connecting shaft 2 which are mutually sleeved, wherein the cross section of the connecting shaft 2 is waist-shaped, two sides of the connecting shaft are torque planes 21, the outer diameter of the connecting shaft 2 is smaller than the inner diameter of the sleeve 1, a pair of angular limiting convex edges 11 are symmetrically arranged on the inner side of the sleeve 1, the cross section of each limiting convex edge 11 is fan-shaped, the vertex angle is a right angle, two sides of each limiting convex edge 11 are mutually vertical torque contact surfaces 111, and when the connecting shaft 2 rotates in the sleeve 1, the two torque planes 21 of the connecting shaft 2 are respectively attached to one torque contact surface 111.
An inclined guide surface 12 is arranged on the inner side of the connecting end of the sleeve 1 connected with the connecting shaft 2. The connecting end of the connecting shaft 2 connected with the sleeve 1 is provided with a guide tip 22. The one end that connecting axle 2 was kept away from to sleeve 1 and the one end that connecting axle 2 kept away from sleeve 1 all are provided with the supporting seat.
Description of specific embodiments:
take the example that the sleeve 1 is connected with the driving shaft of the equipment to be transmitted and the connecting shaft 2 is connected with the driven shaft of the equipment to be transmitted. The driving shaft is concentric with the driven shaft, and a sleeve 11 on the driving shaft can rotate along with the driving shaft to output torque and can axially move under the driving of the driving shaft to perform sleeving and disengaging actions; the driven shaft may be a plurality of shafts, which are connected with the sleeve 1 on the driving shaft one by one, thereby respectively obtaining the torque output from the driving shaft, and the like.
As shown in figure 1, when any driven shaft moves to a position concentric with the sleeve 1 on the driving shaft in operation, the sleeve 1 on the driving shaft moves axially and is sleeved on the connecting shaft 2, and the connecting shaft 2 and the front end of the sleeve 1 are respectively provided with the guide tip 22 and the guide surface 12, so that the sleeve can be sleeved smoothly in a butt joint mode.
As shown in fig. 2, after the sleeve 1 on the driving shaft is successfully sleeved with the connecting shaft 2, the sleeve 1 on the driving shaft idles for 45 degrees, so that the connecting shaft 2 can be driven to rotate, and the mechanism successfully transmits the torque on the sleeve 1 on the driving shaft to the driven shaft through the connecting shaft 2; in the same way, the sleeve 1 is connected with the driven shaft by adopting the connecting shaft 2 to be connected with the driving shaft, and the nesting function and the torque transmission function can also be realized.
