Description
Technical field
The utility model relates to a kind of tension pulley, and particularly a kind of compact type 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.Traditional Idle wheel funtion part (providing torque portions) design is affiliated to respectively by the two ends eave tile of spring and is overlapped and support plate at spring supporting, the spring supporting of the Idle wheel of this structure overlaps and support plate must design the limiting stopper with some strength and mates with spring eave tile (generally one-sided is about 5mm, and diametric(al) is then 10mm); Spring supporting cover is integral type with central axle sleeve, and consider strength problem, it is too small that central axle sleeve physical dimension can not design, and causes radial space demand thus and strengthens; The moment of torsion sometimes needing Idle wheel to provide in accessory wheel system is comparatively large, then need the diameter considering spring, and spring entire outer diameter strengthens, when reversing for avoiding spring, both sides hook place stress is concentrated, and required radial space strengthens.Due to the impact of above series of factors, cause in engine accessory wheel system more and more compacter at present, the utilization of Idle wheel is very limited, and traditional approach adopts hydraulic tensioning wheel can improve this predicament, but hydraulic tensioning wheel cost is higher.
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, and funtion part diameter is little, can be applicable to the compact type tension pulley in compact engine accessory wheel system.
The utility model solves the technological scheme that its technical problem adopts: a kind of compact type 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, described support plate is arranged with spring overlapping in the space that formed with spring supporting, described spring is without eave tile spring, and the spring support sleeve end face corresponding with support plate is provided with one piece of limiting stopper abutted against with the cross section at spring two ends end to end respectively.
As preferably, be provided with spring seat between described spring and support plate, between spring seat and support plate, be provided with damping piece.
As preferably, one end of described central axle sleeve is embedded in spring-loaded and puts, and is provided with panel, is provided with wearing plate between panel and support plate between the described central axle sleeve the other end and support plate.
As preferably, described central axle sleeve is provided with lining.
As preferably, the both sides of described belt pulley are equipped with mazy type dust cover, and belt pulley is fixed with dust cover away from the end face of support plate side by hexagon head shouldered tap bolt, and dust cover is located at outside mazy type dust cover.
The utility model by arranging limiting stopper on spring support sleeve and support plate, abut against with the cross section at the two ends end to end without eave tile spring and reverse, eliminate the space of original spring hook head part, and central axle sleeve is embedded in spring supporting cover, under the prerequisite of proof strength, saves the space of spring supporting cover, funtion part diameter is diminished, diameter can control within 60mm, even less, can use in compact engine accessory wheel system, and structure is simple.

In figure: 1, spring support sleeve, 2, support plate, 3, spring, 4, wearing plate, 5, panel, 6, central axle sleeve, 7, lining, 8, mazy type dust cover, 9, dust cover, 10, hexagon head shouldered tap bolt, 11, belt pulley, 12, damping piece, 13, spring seat.
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 compact type tension pulley as shown in Figure 1 to Figure 3, comprise belt pulley 11 and the support plate 2 being connected belt pulley 11, support plate 2 is provided with spring supporting cover 1 and central axle sleeve 6, central axle sleeve 6 is provided with lining 7, one end of central axle sleeve 6 is embedded on spring support sleeve 1, be provided with panel 5 between central axle sleeve 6 the other end and support plate 2, between panel 5 and support plate 2, be provided with wearing plate 4; Support plate 2 is arranged with spring 3 overlapping in 1 space formed with spring supporting, spring 3 is without eave tile spring, the end face that spring support sleeve 1 is corresponding with support plate 2 is provided with one piece of limiting stopper abutted against with the cross section at spring 3 two ends end to end respectively, be provided with spring seat 13 between spring 3 and support plate 2, between spring seat 13 and support plate 2, be provided with damping piece 12; The both sides of belt pulley 11 are equipped with mazy type dust cover 8, and belt pulley 11 is fixed with dust cover 9 away from the end face of support plate 2 side by hexagon head shouldered tap bolt 10, and dust cover 9 is located at outside mazy type dust cover 8.
In use, spring supporting cover 1 is fixed, support plate 2 drives spring 3 pretension several angle, along with the rotation of spring 3, spring 3 is by the certain moment of torsion of generation and radial positive pressure, this positive pressure is delivered to damping piece 12 by spring seat 13, and damping piece 12 rubs with support plate 2 inner chamber under certain positive pressure, thus produces friction torque.Because spring 3 two ends are without eave tile, and be outer support mode of operation, needs Idle wheel provide comparatively high pulling torque time, spring 3 only needs slightly to increase steel wire diameter and can meet, then saved the space of whole spring 3 external diameter.
The utility model by arranging limiting stopper on spring support sleeve 1 with support plate 2, abut against with the cross section at the two ends end to end without eave tile spring and reverse, eliminate the space of original spring 3 eave tile part, and central axle sleeve 6 is embedded in spring supporting cover 1, under the prerequisite of proof strength, saves the space of spring supporting cover 1, funtion part diameter is diminished, diameter can control within 60mm, even less, can use in compact engine accessory wheel system, and structure is simple.
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.
