Description of drawings
Fig. 1 is structure principle chart of the present utility model, wherein: 1---and the driving shaft joint; 2---the connecting shaft body; 3---fix three pearl thrust-bearings; 4---promotion bearing in bulk; 5---pressure ring; 6---Adjusting bolt Adjusting screw; 7---the driven shaft joint.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: the utility model is used for connecting driving shaft joint 1 and driven shaft joint 7, driving shaft joint 1 is connected with driving shaft and greater than the diameter of described driving shaft, driven shaft joint 7 is connected with driven shaft and greater than the diameter of described driven shaft, comprise connecting shaft body 2, fix three pearl thrust-bearings 3, promotion bearing 4 in bulk, pressure ring 5 and Adjusting bolt Adjusting screw 6, fix three pearl thrust-bearings 3, promotion bearing 4 in bulk, pressure ring 5, Adjusting bolt Adjusting screw 6, driving shaft joint 1 and driven shaft joint 7 and all be positioned at connecting shaft body 2; Be provided with the first ring track on the end face of driving shaft joint 1; Be provided with second ring track corresponding with the first ring track on the end face of driven shaft joint 7, fix three pearl thrust-bearings 3 between driving shaft joint 1 and driven shaft joint 7, the ball of fixing three pearl thrust-bearings 3 is positioned at described the first ring track and described the second ring track; Be provided with the 3rd ring track on the end face of driven shaft joint 7 away from driving shaft one end, be provided with on the end face of one end of pressure ring 5 and the corresponding Fourth Ring of described the 3rd ring track shape track, the ball of promotion bearing 4 in bulk places in described the 3rd ring track and the described Fourth Ring shape track; The other end of pressure ring 5 is connected with the inner of Adjusting bolt Adjusting screw 6, is threaded connection between the inwall of the outer wall of Adjusting bolt Adjusting screw 6 and connecting shaft body 2.
As shown in Figure 1: the ball of fixing three pearl thrust-bearings 3 is three groups of balls, and described three groups of balls are two every group; Bonding connection between pressure ring 5 and the Adjusting bolt Adjusting screw 6; The ball quantity of promotion bearing 4 in bulk is 12.
As shown in Figure 1: when tightening Adjusting bolt Adjusting screw 6, the axial internal clearance of each axle is by asphyxia by external pressure on the chest and abdomen, and it is mutually affixed to be equivalent to each part, master and slave moving axis rotating in same direction; When unscrewing Adjusting bolt Adjusting screw 6, the axial play of each bearing seam increases (disengaged condition that is equivalent to clutch) driven shaft joint 7 and does not rotate with driving shaft; When Adjusting bolt Adjusting screw 6 degrees of tightness appropriateness, driving shaft joint 1 is when clockwise rotating, and frictional force drives three pearl thrust-bearings 3 and retainer rotates, and drives driven shaft joint 7 and rotate with counterclockwise direction.Three balls are all done pure rolling with respect to driving shaft joint 1 and driven shaft joint 7; Because three balls rotate synchronously, under the effect of friction countertorque, driven shaft reverses with respect to driving shaft; Owing to be a contact all, it is main that this coupling is useful in to transmit motion usually rather than transferring power is main occasion; The wider bearing race of nargin to be arranged, to guarantee that it is in the not high adaptivity of coaxality on the end face of part driving shaft joint 1, pressure ring 5 and driven shaft joint 7.
