Abstract
The utility model discloses a crankshaft damping belt pulley, the pulley body of the damping belt pulley is formed by an inner hub (1) and an outer ring (3), the inner hub (1) is connected with the outer ring (3) via a rubber ring (2), and the middle section of the rubber ring (2) is in arc-shaped bending. The utility model can efficiently reduce or remove the vibration of engines, and improves the comfort of vehicles.
Description
Technical field
The utility model relates to a kind of belt pulley, particularly relates to a kind of bent axle damper pulley.
Background technique
Traditional crank pulley is the rigidity belt pulley, is processed into through turning by cast iron or cast steel, and its function is transferring power and moment of torsion.This rigidity belt pulley can not effectively reduce or eliminate the vibration of motor, its result when the rotating speed of bent axle changes: the one, and the life-span of reducing motor; The 2nd, can't satisfy the travelling comfort of vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of bent axle damper pulley that can effectively reduce or eliminate engine luggine.
For achieving the above object, the solution that the utility model adopts is: the wheel body of this damper pulley is made of inner wheel hub and outer ring, connects by rubber ring between inner wheel hub and the outer ring.
The stage casing of the above-mentioned rubber ring shape that is convexly curved, corresponding inner wheel hub also is identical arc-shaped bend shape with the outer ring.
Above-mentioned rubber ring inserted dual mode: the one, by vulcanizer rubber is infused between inner wheel hub and the outer ring, and bonding with the sulfuration binder; The 2nd, with being pressed into frock rubber ring directly is pressed between inner wheel hub and the outer ring.
The utility model can play certain buffer function because rubber ring has elasticity, and therefore have following advantage: (1) can effectively reduce or eliminate the vibration of motor, reduces the noise of motor; (2) travelling comfort of raising vehicle.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model.
Embodiment
As shown in Figure 1, the utility model has resolved into inner wheel hub 1 and outer ring 3 with the integrated type wheel body of former belt pulley, inner wheel hub 1 joins with bent axle, outer ring 3 is connected with systems such as motor, water pumps by belt pulley, the utility model is provided with rubber ring 2 between inner wheel hub 1 and outer ring 3, inner wheel hub 1 is connected by rubber ring 2 with outer ring 3, the stage casing of this rubber ring 2 shape that is convexly curved, corresponding inner wheel hub 1 also is identical arc-shaped bend shape with outer ring 3, its objective is to prevent rubber ring 2 axial floats.The implantation mode of rubber ring has two kinds: the one, by vulcanizer rubber is infused between inner wheel hub and the outer ring, and bonding with the sulfuration binder; The 2nd, with being pressed into frock rubber ring directly is pressed between inner wheel hub and the outer ring.The physical dimension of inner wheel hub 1 and outer ring 3 should satisfy the belt pulley performance and the motor natural frequency of vibration is complementary.
Use the utility model when the rotating speed of bent axle changes, because rubber ring 2 has buffer function, can reduce or eliminate the vibration of motor, it is more comfortable that vehicle is sat up.
Claims (2)
1. a shock-proof crank pulley comprises the belt pulley wheel body, it is characterized in that: wheel body is made of inner wheel hub (1) and outer ring (3), and inner wheel hub (1) is connected by rubber ring (2) with outer ring (3).
2. a kind of shock-proof crank pulley according to claim 1 is characterized in that: the stage casing of rubber ring (2) shape that is convexly curved, corresponding inner wheel hub (1) also is identical arc-shaped bend shape with outer ring (3).
