Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises combination 1 of input half-coupling and coupled output half-coupling combination 12.
Make up 1 place at the input half-coupling and be provided with input end cap 2, input end cap 2 is connected with pressure head I 5 contacts, pressure head I 5 is connected with an end of spring 6, the other end of spring 6 connects pressure head II 9, pressure head II 9 is connected with pressing plate 10, and be connected with friction plate 8 by pressing plate 10, friction plate 8 is connected with input half-coupling combination 1.For reaching better technique effect, in the utility model, pressure head I 5 has six, each pressure head I 5 all connects a spring 6, and each spring 6 all connects a pressure head II 9, and six pressure head II 9 all are connected with a pressing plate 10, like this, six pressure head II9 can affact pressure on the pressing plate 10, thereby stressed even, and dynamics increases.In addition, in the utility model, pressure head I 5 is the arc pressure head, and friction plate 8 is an asbestos friction sheet, also can be nylon jacket or the like.And, when input end cap 2 screws in appropriate depth, can tighten to be positioned at and screw bolt 3 on the input end cap 2, loosening to prevent input end lid 2.
Make up 12 places at the output half-coupling and be provided with output end cap 11, output end cap 11 connects Brake drum 7 by bolt 13.Need to prove,, all need to dispose packing ring 4 for cooperation screws the proper functioning of bolt 3 and bolt 13.
Three kinds of functions and each working principle that the utility model is realized are as follows:
1), the realization of braking function: when needing braking, the Brake drum 7 of break bearing shell by holding moment limiting device tightly realized braking function.
2), connect the realization of transmission agency:, can realize being connected of input shaft and output shaft by two half-coupling combinations.At input shaft end, the combination 1 of input half-coupling connects by key and is connected with the motor input shaft, and the motor input shaft drives input half-coupling combination 1 and rotates.Input end cap 2 itself is slotted, tighten by screwing bolt 3, produce pressure, affact on the M180 screw thread, play locking effect, and input end cap 2 is adjusted by screw thread M180 and is screwed into the degree of depth, compress 5, six pressure head I 5 of six pressure head I pressure is affacted on six springs 6, make spring 6 produce compressive strain and produce pressure spring power, the pressure spring masterpiece is used on other six pressure head II 9 and is produced positive pressure, these six pressure head II 9 affact pressure on the pressing plate 10, and this pressing plate 10 produces frictional force by asbestos friction sheet 8 and input half-coupling combination 1, by the effect of frictional force, closely be connected with input half-coupling combination 1, produce synchronously and rotate.Simultaneously, Brake drum 7 is by M180 scyewed joint and pressure head and input half-coupling combination 1 rotation synchronously.The output end cap 11 of output terminal is connected rotation synchronously by bolt 13 with Brake drum 7, output half-coupling combination 12 combinations realize functions such as vibration damping, buffering and compensation by elastic sleeve, can compensate the diaxon relativity shift, be equivalent to a rubbercushioned sleeve bearing coupling, rotate synchronously with the combination of input end half-coupling, rotate synchronously thereby drive output shaft.
