Abstract
The utility model discloses a shock absorption belt pulley which comprises a belt pulley outer ring, a belt pulley inner ring and a rubber ring which is arranged between the belt pulley outer ring and the belt pulley inner ring. A connection groove is formed in the outer wall of the belt pulley outer ring. The belt pulley outer ring is connected with the belt pulley inner ring through the rubber ring in a friction transmission mode. The inner wall of the belt pulley outer ring is provided with a press fitting limit flange which is matched with the belt pulley inner ring. The shock absorption belt pulley further comprises belt pulley shell bodies. The number of the belt pulley shell bodies is two. The two belt pulley shell bodies are symmetrically arranged. Clamping brims are arranged inside the belt pulley shell bodies and matched with the connection groove. The belt pulley outer ring and the outer walls of the belt pulley shell bodies are all provided with sand blasting treatment layers. The installation precision among the belt pulley outer ring, the belt pulley inner ring and the rubber ring is improved.
Description
Technical field
The utility model belongs to the automobile transmission part field, is specifically related to a kind of damper pulley.
Background technique
Now, the automobile engine front end accessory drive train is increasingly sophisticated, and the accessory power of belt demand motive and rotary inertia are also increasing.The train design has directly affected the reliability of car load.The belt train is driven by bent axle and belt pulley, and belt pulley and bent axle are rigidly connected, and the fluctuation of speed of bent axle is directly passed on the belt pulley, causes the impulsive load to belt pulley, has affected the stationarity of each accessory drive; Strengthen the percussion to belt, reduced the working life of belt pulley, aggravated vibrating noise.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of damper pulley is provided, and has improved the installation precision between belt pulley outer ring, belt pulley inner ring and the rubber ring three.
The technological scheme that the utility model adopts is: a kind of damper pulley, comprise the belt pulley outer ring, belt pulley inner ring and be arranged at the belt pulley outer ring, rubber ring between the belt pulley inner ring, the outer ring outer wall of described belt pulley has connecting groove, the belt pulley outer ring is connected with belt pulley inner ring friction driving by rubber ring, belt pulley outer ring inwall is provided with the spacing rib that press-fits with belt pulley inner ring coupling, also comprise the belt pulley housing, described belt pulley housing is two, two belt pulley housings are symmetrical arranged, the belt pulley enclosure interior is provided with the edge with the connecting groove coupling, and belt pulley outer ring and belt pulley housing outer wall are equipped with the sand blast layer.
As preferably, the surface of contact of belt pulley outer ring, belt pulley inner ring and rubber ring is ripple type.
The beneficial effects of the utility model are: the spacing rib that press-fits of setting has improved installation precision between belt pulley outer ring, belt pulley inner ring and the rubber ring.Rubber ring is arranged between belt pulley inner ring and the belt pulley outer ring, has reduced the impact that drive pulley brings, and has prolonged working life.The sand blast layer the intensity that has improved belt pulley is set, increase its anti-fatigue performance, reduced the infringement of vibrations to bent axle.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, belt pulley outer ring; 2, belt pulley inner ring; 3, rubber ring; 4, press-fit spacing rib; 5, belt pulley housing.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of damper pulley, comprise belt pulley outer ring 1, belt pulley inner ring 2 and be arranged at belt pulley outer ring 1, rubber ring 3 between the belt pulley inner ring 2, described belt pulley outer ring 1 outer wall has connecting groove, belt pulley outer ring 1 is connected with belt pulley inner ring 2 friction driving by rubber ring 3, belt pulley outer ring 1 inwall is provided with the spacing rib 4 that press-fits with belt pulley inner ring 2 couplings, also comprise belt pulley housing 5, described belt pulley housing 5 is two, two belt pulley housings 5 are symmetrical arranged, belt pulley housing 5 inside are provided with the edge with the connecting groove coupling, and belt pulley outer ring 1 and belt pulley housing 5 outer walls are equipped with the sand blast layer.As preferably, belt pulley outer ring 1, belt pulley inner ring 2 are ripple type with the surface of contact of rubber ring 3.
During use, belt pulley inner ring 2 is connected with bent axle, belt pulley outer ring 1 drive pulley housing 5, thus drive belt.Rubber ring 3 the spatial position that has guaranteed between belt pulley outer ring 1 and the belt pulley inner ring 2 is set.When the rotation speed change of bent axle, belt pulley inner ring 2 is along with bent axle rotates, and belt pulley outer ring 1 is because the inertia of train keeps original speed to rotate.Therefore, exist certain speed poor between belt pulley inner ring 2 and the belt pulley outer ring 1.This fast missionary society is blocked by the of short duration friction that rubber ring 3 produces, and the bent axle in this time has commutated, and can reduce like this velocity variations amplitude and the speed of belt pulley outer ring 1.
Claims (2)
1. damper pulley, it is characterized in that: comprise the belt pulley outer ring, belt pulley inner ring and be arranged at the belt pulley outer ring, rubber ring between the belt pulley inner ring, the outer ring outer wall of described belt pulley has connecting groove, the belt pulley outer ring is connected with belt pulley inner ring friction driving by rubber ring, belt pulley outer ring inwall is provided with the spacing rib that press-fits with belt pulley inner ring coupling, also comprise the belt pulley housing, described belt pulley housing is two, two belt pulley housings are symmetrical arranged, the belt pulley enclosure interior is provided with the edge with the connecting groove coupling, and belt pulley outer ring and belt pulley housing outer wall are equipped with the sand blast layer.
2. damper pulley according to claim 1, it is characterized in that: the surface of contact of belt pulley outer ring, belt pulley inner ring and rubber ring is ripple type.
