Description
Technical field
The utility model relates to a kind of tension pulley, particularly the symmetrical high damping tension pulley of one.
Background technique
In vehicle transmission, belt transmission application widely.In motor car engine, the speed exported due to bent axle is non-constant, the power consumpiton of the parts such as air compressor, generator, water pump, the tension force of belt in accessory wheel system is caused to be among change, the length of belt is also among change, belt can produce shake, in order to ensure that reliable transmission is effective, installing tension pulley and being necessary very much.At present, the damping of tension pulley market adopted is all little.In the running of motor, when belt tension increases, the length of belt changes, thus produces shake, and the support arm of belt drives tension pulley significantly rotates, thus causes tension pulley to damage; When belt tension reduces, just in time contrary when increasing with belt tension, the support arm of tension pulley drives belt pulley to deflect under the action of the spring, increase total driving moment, thus cause the power be applied on belt to become large, increase belt and use fatigue strength, thus reduce the working life of belt.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and the utility model provides the symmetrical high damping tension pulley that a kind of structure is simple, reasonable in design, damping is high, sealing is strong.
The utility model solves the technological scheme that its technical problem adopts: a kind of symmetrical high damping tension pulley, and comprise belt pulley and the support arm being connected belt pulley, described support arm is connected with spring supporting cover by central shaft; Be provided with the first cavity between described support arm and spring supporting overlap, described support arm and spring supporting are enclosed within the first cavity and are arranged with spring, and the two ends of described spring are connected with support arm, spring supporting cover respectively; Described spring supporting is enclosed within central shaft and is provided with the second cavity away from one end of support arm, described central shaft is arranged with wearing plate, panel in the second cavity, described panel is fixedly connected with central shaft, described wearing plate is located at the side that panel overlaps towards spring supporting, the inwall that described wearing plate is enclosed within the second cavity by panel and spring supporting abuts against, and is arranged with belleville spring between described wearing plate and spring supporting overlap.
Adopt said structure, in engine running, when belt tension increases, the support arm of belt drives tension pulley rotates, cause spring to reverse and produce torsional resistance, panel and wearing plate also relative spin friction generation surface friction drag simultaneously, the moment of these the two kinds resistance formation simultaneously produced can overcome the driving of belt to Idle wheel support arm, reduces the shake of belt; When belt tension reduces, Idle wheel support arm can drive belt, just in time contrary when increasing with belt tension, spring reverses and produces driving force, and panel and wearing plate also relative spin friction generation surface friction drag, this resistance can offset a part of Spring driving power, total driving moment is caused to reduce, the power be applied on belt is less, effectively can slow down the fatigue strength of belt, reduce the loss to belt life.
As preferably, described belt pulley is connected with support arm by bolt.Adopt said structure, ensure that the working stability of belt pulley.
As preferably, described belt pulley is provided with rear dust cover towards support arm side, is provided with front dust cover away from support arm side.Adopt said structure, improve the sealing of tension pulley, thus improve working life.
As preferably, between described support arm and spring supporting overlap, be provided with dust washer.Adopt said structure, not only can improve the sealing of tension pulley, and in motor running, when belt tension increases or reduce, all can produce surface friction drag between support arm and dust washer, thus reduce the shake of belt or improve the working life of belt.
As preferably, between described central shaft and spring supporting overlap, be provided with self oiling bearing.Adopt said structure, improve the working stability of tension pulley.
As preferably, the both sides of described wearing plate abut against with panel, belleville spring respectively.Adopt said structure, ensure that fully contacting of wearing plate and panel, thus improve damping and the working stability of tension pulley.
As preferably, the outside of described support arm, spring supporting cover is connected by connecting pin.Adopt said structure, improve the structure stability of tension pulley.
The utility model has the features such as structure is simple, reasonable in design, damping is high, sealing is strong.

Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
The symmetrical high damping tension pulley of one as shown in Figure 1, comprise belt pulley 13 and the support arm 1 being connected belt pulley 13, described belt pulley 13 is connected with support arm 1 by bolt 12, and described belt pulley 13 is provided with rear dust cover 10 towards support arm 1 side, is provided with front dust cover 11 away from support arm 1 side; Described support arm 1 is connected with spring supporting cover 4 by central shaft 8, the outside of described support arm 1, spring supporting cover 4 is connected by connecting pin 14, described support arm 1 and spring supporting are provided with dust washer 2 between overlapping 4, and described central shaft 8 and spring supporting are provided with self oiling bearing 9 between overlapping 4; Described support arm 1 and spring supporting are provided with the first cavity between overlapping 4, and described support arm 1 overlaps 4 with spring supporting and be arranged with spring 3 in the first cavity, and the two ends of described spring 3 are overlapped 4 with support arm 1, spring supporting respectively and are connected; Described spring supporting cover 4 is provided with the second cavity at central shaft 8 away from one end of support arm 1, described central shaft 8 is arranged with wearing plate 5, panel 6 in the second cavity, described panel 6 is fixedly connected with central shaft 8, described wearing plate 5 is located at the side of panel 6 towards spring supporting cover 4, described wearing plate 5 overlaps 4 inwalls in the second cavity by panel 6 and spring supporting and abuts against, described wearing plate 5 and spring supporting are arranged with belleville spring 7 between overlapping 4, and the both sides of described wearing plate 5 abut against with panel 6, belleville spring 7 respectively.
