A kind of claw type belt pulley that the utility model provides, its cleaning hook stretches in race, mud or the weeds of race inner clip band can be cleared up, effectively can ensure the working life of belt pulley, add the reliability of product, and increase preventing dust water cover and preventing dust hydrosphere at belt pulley dual-side, can prevent dust, rainwater or slime water etc. from entering in belt pulley bearing and wheel shaft, in case cause bearing and wheel shaft to get rusty, thus have impact on the working life of product, increase maintenance cost.
In some embodiments, the sheathed described wheel shaft of described retaining ring, the end that described wheel shaft exposes wheel body has outside thread, and described wheel shaft has the described externally threaded nut of cooperation, and described retaining ring is fixed on described wheel shaft by described nut.This design is by the means of fixation of caption nut clamping cleaning hook, and make its structure simple, mounting type is simple and easy, and easily implements.
In some embodiments, bullet pad is provided with between described retaining ring and described nut.The use of bullet pad strengthens the fixing effect of nut.
In some embodiments, between described bullet pad and described nut, be provided with flat gasket, between described bullet pad and described retaining ring, be also provided with flat gasket.The use of flat gasket strengthens the stability between component, and fixed effect is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of claw type belt pulley of a kind of mode of execution of the present utility model;
Fig. 2 is the structural representation of the cleaning hook of a kind of claw type belt pulley of a kind of mode of execution of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in more detail.
As shown in Figure 1, a kind of claw type belt pulley, comprise the coaxial wheel body 1, bearing 2 and the wheel shaft 3 that arrange, wheel shaft 3 is plugged in bearing 2, and wheel body 1 is sheathed on bearing 2, and wheel body 1 is provided with race 4 with the hoop of belt contacts; Wheel body 1 adopts high performance engineering plastics to make, and as wear-resisting nylon material or acetal resin etc., adopts high performance engineering plastics that the wear resistance of wheel body 1 can be made better, not fragile, more reliably.
As shown in Figure 2, cleaning hook 5 comprises and is fixed on retaining ring 6 on wheel shaft 3 and U-shaped hook 7, U-shaped hook 7 comprises two straight-bars 8 and the arc-shaped transition bar 9 being connected two straight-bars 8, retaining ring 6 and U-shaped hook is one-body molded or adopt material during tensile bending to form, and one of them straight-bar 8 stretches in race 4.Be provided with preventing dust hydrosphere 13 between wheel body 1 and retaining ring 6, preventing dust hydrosphere 13 is fixedly connected on wheel body 1 side by spiral way, is provided with the hole consistent with wheel shaft 3 diameter in the middle of preventing dust hydrosphere 13, and wheel shaft 3 is through hole; The another side of wheel body 1 is provided with preventing dust water cover 14, and preventing dust water cover 14 is fixedly connected on wheel body 1 by spiral way.
The end that wheel shaft 3 exposes wheel body 1 has outside thread, and wheel shaft 3 has the externally threaded nut 10 of cooperation, and retaining ring 6 is fixed on wheel shaft 3 by nut 10, this design clamps the means of fixation of cleaning hook 5 by caption nut 10, make its structure simple, mounting type is simple and easy, and easily implements.Between retaining ring 6 and nut 10, be provided with bullet pad 11, the use of bullet pad 11 strengthens the fixing effect of nut 10.Be provided with flat gasket 12 between bullet pad 11 and nut 10, be also provided with flat gasket 12 between bullet pad 11 and retaining ring 6, the use of flat gasket 12 strengthens the stability between retaining ring 6 and wheel body 1, and fixed effect is better.
