Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along A-A direction.
Detailed description of the invention
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As depicted in figs. 1 and 2, a kind of pulley of decelerating clutch of washing machine, comprise the installing rack 2 be located at below belt pulley 1 and the friction brakes 3 be located on installing rack 2 and bolt-type brake 4, this belt pulley 1 is fixedly linked with the power shaft 7 of decelerating clutch of washing machine, namely being rotated by belt pulley 1 is with driven input shaft 7 to rotate, thus provides power for whole decelerating clutch of washing machine.
Installing rack 2 is fixedly linked with the shell of decelerating clutch of washing machine, the external peripheral surface of this belt pulley 1 is provided with belt grooves 11, brake hoop 12 and groove 13, wherein belt grooves 11 is used for assembling driving belt, this friction brakes 3 matches with brake hoop 12 simultaneously, this bolt-type brake 4 matches with groove 13, namely pass through the double action of friction brakes 3 and bolt-type brake 4, can realize braking belt pulley 1 fast.
Friction brakes 3 comprises two the contact blocks 31 being arranged with belt pulley 1 both sides, two contact blocks 31 are arch, and this contact block 31 matches with brake hoop 12 on belt pulley 1, thus make when contact block 32 compresses brake hoop 12, belt pulley 1 can be subject to larger frictional force, thus can realize braking as soon as possible.Installing rack 2 is provided with erection column 21, this erection column 21 offers relative installing hole 5 with on the lower end of contact block 31, is provided with latch 6 in this installing hole 5, namely the lower end of contact block 31 and erection column 21 hinged by latch 6.The upper end of two contact blocks 31 is connected by connecting rod 32, this contact block 31 is flexibly connected with connecting rod 32, the both ends of this connecting rod 32 are equipped with back-moving spring 33, this back-moving spring 33 is connected with contact block 31, and the upper end of two contact blocks 31 is also connected by drive unit 34, this drive unit 34 is double piston-rod cylinder, and two piston rods 341 of this drive unit 34 are fixedly linked with the upper end of two contact blocks 32 respectively.When passing into pressure-air in drive unit 34, its two piston rods 341 stretch out respectively to both sides, thus promote the motion of two contact blocks 31 belt pulley 1 dorsad, are compressed by back-moving spring 33 simultaneously, now contact block 31 is separated with the brake hoop 12 on belt pulley 1, and belt pulley normally works; And when stopping in drive unit 34 passing into pressure-air, under the elastic force effect of back-moving spring 33, contact block 31 moves to the direction of belt pulley 1, and is squeezed in tightly on the brake hoop 12 of belt pulley 1 under the elastic force effect of back-moving spring 33, thus can realize braking belt pulley 1.
