As extremely shown in Figure 7 in Fig. 1, shaft end nut 1, spline ring 2 connects end cap 3, fitting-up bolt 4, attachment bolt 5, dynamic balancer universal-joint 6, axletree 7, protruding key 8, boss 9, tapped bore 10, tapped bore 11, through hole 12, through hole 13.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 to 7, the EMU wheel comprises the axle head actuating device: shaft end nut 1, spline ring 2, connection end cap 3, fitting-up bolt 4, attachment bolt 5, dynamic balancer universal-joint 6, axletree 7.
The assembly method of EMU wheel to the axle head actuating device: shaft end nut 1 is tightened on axle of motor train unit 7 axle head screw threads, spline ring 2 is installed, protruding key 8 in spline ring 2 is coordinated with axletree 7 axle head keyways, adjust shaft end nut 1, guarantee that the through hole 12 on spline ring 2 overlaps with the tapped bore 11 of shaft end nut 1, then install to connect end cap 3, and will connect end cap 3 and spline ring 2, shaft end nut 1 are connected into one with fitting-up bolt 4.To connect at last end cap 3 links up with dynamic balancer upper cardan 6.In this way, can realize dynamic balancer to EMU wheel to driving.
Characteristics of the present utility model are, described EMU wheel is locked axletree 7 axle head screw threads by shaft end nut 1 the axle head actuating device; Undertaken locking and the position is fixed by the screw thread of 2 pairs of shaft end nuts 1 of spline ring and axletree 7; By attachment bolt 5 with shaft end nut 1, spline ring 2 and connect end cap 3 and combine as a whole.
Adopt the reason of spline ring 2: because axle of motor train unit 7 axle heads are helicitic texture, and the kinetic balance drive wheel need to transmit very large moment of torsion when rotating, if when adopting simple thread connection form to drive, if driving direction is identical with the screw-threaded coupling direction, screw thread can be tightened in axle head with excessive moment of torsion with shaft end nut 1 on the locking direction, even can damage the axle head screw thread; If driving direction and screw-threaded coupling opposite direction can rotate on the direction that the axle head screw thread gets loose at twisting force lower shaft end nut 1, can not realize the driving effect, shaft end nut 1 can occur and break away from the axle head screw thread, make wheel to breaking away from the danger of dynamic balancer.
In order to prevent above-mentioned appearance of asking a question, according to axletree 7 axle head structures, designed spline ring 2, by two protruding keys 8 of spline ring 2, shaft end nut 1 can be positioned at axletree 7 axle head screw thread fixed positions.
Shaft end nut 1, spline ring 2 and connect the mode that is connected and fixed of end cap 3: evenly be provided with 16 tapped bore 11 at shaft end nut 1 end face, evenly be provided with 24 through holes 12 at spline ring 2 end faces, can make in tapped bore 11 and spline ring 2 through holes 12 by fine adjustment shaft end nut 1 has four can overlap, by these four holes, shaft end nut 1 and spline ring 2 can be fixed as one.Connecting the outer circle of end cap 3 has eight through holes 13, by wherein four, can shaft end nut 1, spline ring 2 and connection end cap 3 be connected to one with attachment bolt 5.
The structure that is connected and fixed that connects end cap 3 and shaft end nut 1, spline ring 2 makes and connects end cap 3 and have the self-centering function, and after it was installed on axle head, its axle center can overlap with axle axis.
The mode that is connected and fixed that connects end cap 3 and dynamic balancer universal-joint 6: be provided with boss 9 connecting on end cap 3 end faces, be provided with six tapped bore 10 on boss 9, six fitting-up bolts 4 pass through hole on dynamic balancer universal-joint 6 and are fixed on tapped bore 10 on boss 9, to connect end cap 3 and captive joint with dynamic balancer universal-joint 6, connect axle center that boss 9 on end cap 3 guaranteed to connect end cap 3 and dynamic balancer universal-joint 6 point-blank.
Take turns the axle head actuating device by this EMU, EMU axletree 7 and dynamic balancer universal-joint 6 can be coupled together, and guaranteed that dynamic balancer driving center and axle of motor train unit 7 axis on same straight line, have reduced the interference that desaxe brings to dynamic balancing test.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
