Abstract
A kind of high-mechanic tension pulley, comprise belt pulley and the support plate being connected belt pulley, described support plate is provided with spring supporting cover and central axle sleeve, spring is provided with in described spring supporting cover, spring backing plate is provided with in described spring, packing ring is provided with between described spring supporting cover and support plate, double row angular contact bearing is provided with in described belt pulley, and the inherent double row angular contact bearing both sides of belt pulley are provided with dust cover, described belt pulley end face is fixed with front cover by hexagon head shouldered tap bolt, and front cover is located at outside dust cover; The utility model instead of traditional single-groove grooved ball bearing by double-row angular ball, larger radial load can be born, certain thrust load can be born again, and bearing swing angle is little, bearing sealed ring stressed more even, and be also provided with dust cover and front cover, improve sealability, thus improve working life and the stability of tension pulley.
Description
Technical field
The utility model relates to a kind of tension pulley, and particularly a kind of high-mechanic 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 working life of tension wheel shaft bearing is the key element affecting Idle wheel working life, especially at engineering and mining machinery diesel engine tension pulley, these diesel engine overwhelming majority are high-powered engine, the operating mode of tension pulley is very severe, the belt tension wheel bearing of conventional construction is single-groove grooved ball bearing, because its rate performance is better, price inexpensively, this bearing is widely used in passenger car tension pulley, and on truck Idle wheel, there are 2 deficiencies: 1, all larger (the 8PK/10PK/12PK poly Vbelt etc. of radial load suffered by bearing, and passenger car is generally no more than 6PK), 2, the wedge number of belt is more, corresponding belt pulley width is wider, in this case the bigger than normal to play of single row bearing axle is adopted, the swing angle of belt pulley is caused to make more greatly stationarity in belt pulley using process poor after press-in belt pulley endoporus.Therefore, adopt the truck Idle wheel of traditional single-groove grooved ball bearing larger relative to the inefficacy ratio (PPM value) of passenger car Idle wheel.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and the utility model provides that a kind of stationarity is good, sealability is high, can bear the high-mechanic tension pulley of larger load.
The utility model solves the technological scheme that its technical problem adopts: a kind of high-mechanic tension pulley, comprise belt pulley and the support plate being connected belt pulley, described support plate is provided with spring supporting cover and central axle sleeve, spring is provided with in described spring supporting cover, spring backing plate is provided with in described spring, packing ring is provided with between described spring supporting cover and support plate, double row angular contact bearing is provided with in described belt pulley, and the inherent double row angular contact bearing both sides of belt pulley are provided with dust cover, described belt pulley end face is fixed with front cover by hexagon head shouldered tap bolt, and front cover is located at outside dust cover.
As preferably, described support plate end face is provided with end cap, and end cap and spring supporting cover, central axle sleeve three are concentric, and is provided with butterfly spring seat in the groove that formed between overlapping of end cap and spring supporting, is provided with butterfly spring in described butterfly spring seat.
As preferably, described central axle sleeve is provided with lining.
As preferably, between described packing ring and spring supporting overlap, be provided with flat board.
The utility model instead of traditional single-groove grooved ball bearing by double-row angular ball, can bear larger radial load, can bear certain thrust load again; And double-row bearing is integral type bearing; when wheel train co-plane is poor; especially 8PK ~ 12PK poly Vbelt train; use this structural type bearing, the unbalanced load protection for belt pulley has and improves effect greatly, and bearing swing angle is little; bearing sealed ring stressed more even; and be also provided with dust cover and front cover, improve sealability, thus improve working life and the stability of tension pulley.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
In figure: 1, spring supporting cover, 2, support plate, 3, central axle sleeve, 4, lining, 5, spring backing plate, 6, spring, 7, dull and stereotyped, 8, packing ring, 9, dust cover, 10, hexagon head shouldered tap bolt, 11, front cover, 12, belt pulley, 13, double row angular contact bearing, 14, butterfly spring seat, 15, end cap, 16, butterfly spring.
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 high-mechanic tension pulley as shown in Figure 1, comprises belt pulley 12 and the support plate 2 being connected belt pulley 12, and support plate 2 is provided with spring supporting cover 1 and central axle sleeve 3, and central axle sleeve 3 is provided with lining 4; Be provided with spring 6 in spring supporting cover 1, be provided with spring backing plate 5 in spring 6, be provided with packing ring 8 between spring supporting cover 1 and support plate 2, packing ring 8 and spring supporting are provided with dull and stereotyped 7 between overlapping 1; Be provided with double row angular contact bearing 13 in belt pulley 12, and belt pulley 12 inherent double row angular contact bearing 13 both sides are provided with dust cover 9, belt pulley 12 end face is fixed with front cover 11 by hexagon head shouldered tap bolt 10, and front cover 11 is located at outside dust cover 9; Support plate 2 end face is provided with end cap 15, and end cap 15 and spring supporting overlap 1, central axle sleeve 3 three is concentric, and end cap 15 and spring supporting overlap in the groove that formed between 1 and be provided with butterfly spring seat 14, are provided with butterfly spring 16 in described butterfly spring seat 14.
The utility model instead of traditional single-groove grooved ball bearing by double-row angular ball 13, can bear larger radial load, can bear certain thrust load again; And double-row bearing 13 is integral type bearing; when wheel train co-plane is poor; especially 8PK ~ 12PK poly Vbelt train; use this structural type bearing, the unbalanced load protection for belt pulley has and improves effect greatly, and bearing swing angle is little; bearing sealed ring stressed more even; and be also provided with dust cover 9 and front cover 11, improve sealability, thus improve working life and the stability of tension pulley.
