Description
Technical field
The utility model relates to a kind of tension pulley, and particularly a kind of asymmetric damping tension pulley, belongs to mechanical transmission field of accessories.
Background technique
In vehicle transmission, belt transmission application widely, in order to ensure that reliable transmission is effective, being installed tension pulley and being necessary very much.The damping of Idle wheel is the key element in accessory wheel system, the damping of tradition Idle wheel, possess certain axial positive pressure and put on friction pair generation frictional damping, and positive pressure reaches certain decrement by belleville spring provides, in conventional belt Idle wheel, the decrement of belleville spring is changeless, so the positive pressure that belleville spring produces is constant, the product of positive pressure and friction factor is constant (frictional damping is constant), be symmetrical damping, there is certain risk in symmetrical damping, when damping value acquire a certain degree (generally more than 50%) easily there is not reply phenomenon, and show output torque deficiency, wheel train belt tension force is caused to occur skidding not.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and it is simple that the utility model provides a kind of structure, effectively can avoid the asymmetric damping tension pulley occurring skidding because belt tension is inadequate.
The utility model solves the technological scheme that its technical problem adopts: a kind of asymmetric damping tension pulley, comprise belt pulley, connect the support plate of belt pulley, described support plate is provided with spring support sleeve and central axle sleeve, described spring support sleeve is embedded in support plate, described central axle sleeve runs through support plate and spring support sleeve, and support plate, spring support sleeve, central axle sleeve is coaxially set, described support plate is arranged with spring in the space formed with spring support sleeve, spring is provided with spring seat, spring seat is provided with damping piece away from spring side, and damping piece contacts with the inwall of support plate.
As preferably, described spring is without eave tile spring, and the spring support sleeve end face corresponding with support plate is provided with the limiting stopper abutted against with the cross section at spring two ends end to end respectively.
As preferably, between described support plate and central axle sleeve, be provided with self oiling bearing.
As preferably, described belt pulley is fixed with dust cover away from the end face of support plate side by hexagon head shouldered tap bolt.
The utility model by being provided with spring seat on spring, spring seat arranges the damping piece that to contact with the inwall of support plate, when loading moment of torsion, load the friction torque sum that moment of torsion is spring torque and damping piece, when train is loaded, have enough large loading moment of torsion to suppress the shake of belt; During unloading moment of torsion, unloading moment of torsion is the difference of the friction torque of spring torque and damping piece, has enough belt tensions to avoid the slip risk of train, and also have the features such as structure is simple during unloading.

Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
A kind of asymmetric damping tension pulley as shown in Figure 1 to Figure 3, comprise belt pulley 9, connect the support plate 2 of belt pulley 9, support plate 2 is provided with spring support sleeve 1 and central axle sleeve 3, spring support sleeve 1 is embedded in support plate 2, central axle sleeve 3 runs through support plate 2 and spring support sleeve 1, and support plate 2, spring support sleeve 1, central axle sleeve 3 are coaxially set, and are provided with self oiling bearing 10 between support plate 2 and central axle sleeve 3; Support plate 2 is arranged with spring 4 in the space formed with spring support sleeve 1, and spring 4 is without eave tile spring, and spring support sleeve 1 end face corresponding with support plate 2 is provided with the limiting stopper abutted against with the cross section at spring 4 two ends end to end respectively; Spring 4 is provided with spring seat 5, and spring seat 5 is provided with damping piece 6 away from spring 4 side, and damping piece 6 contacts with the inwall of support plate 2.Belt pulley 9 is fixed with dust cover 8 away from the end face of support plate 2 side by hexagon head shouldered tap bolt 7.
In use, spring supporting cover 1 is fixed, support plate 2 drives spring 4 pretension several angle, along with the rotation of spring 4, spring 4 is by the certain moment of torsion of generation and radial positive pressure, this positive pressure is delivered to damping piece 6 by spring seat 5, damping piece 6 rubs with support plate 2 inner chamber under certain positive pressure, thus generation friction torque, and spring 4 is along with the increase of angle of swing, the positive pressure produced also progressively increases, thus friction torque also progressively increases, spring 4 is along with the reduction of angle of swing, the positive pressure produced also progressively reduces, thus friction torque also progressively reduces.
The utility model by being provided with spring seat 5 on spring 4, spring seat 5 arranges the damping piece 6 that to contact with the inwall of support plate 2, when loading moment of torsion, load the friction torque sum that moment of torsion is spring torque and damping piece 6, when train is loaded, have enough large loading moment of torsion to suppress the shake of belt; During unloading moment of torsion, unloading moment of torsion is the difference of the friction torque of spring torque and damping piece 6, has enough belt tensions to avoid the slip risk of train, and also have the features such as structure is simple during unloading.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technological scheme described in claim.
