Description
Technical field
The utility model relates to automobile engine front end accessory drive technology field, particularly relates to a kind of superimposed sheets spring formula stretcher.
Background technique
Stretcher is holding device conventional on belt drive system, be characterized in keeping belt can have suitable tension force tightening belt in transmission process, avoid belt slippage, jump tooth, de-tooth phenomenon, also can prevent belt from loosening, come off, the structure of stretcher comprises stationary structure and elasticity self-regulation structure, and conventional tensioners can not varied tention and moment of torsion flexibly, and the utility model adopts the automatic adjusting belt tension of elastic member.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of superimposed sheets spring formula stretcher.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of superimposed sheets spring formula stretcher, comprise: base, sheet spring, tension arms, axle sleeve, pivot, band wheel assembly and dust cover, described sheet spring is made up of the steel disc that three increase successively, the inwall of described base is evenly provided with 4 sheet springs, one end, left side on described tension arms is provided with a through hole, the arranged outside of described through hole has the central shaft outer wall of circular arc, described central shaft outer wall is evenly provided with 4 sheet springs contrary with direction on base inner wall, base and tension arms and axle sleeve are fixed together through tension arms by described pivot, one end, right side of described tension arms is provided with band wheel assembly and dust cover, sheet spring on described tension arms and the longer a slice of the sheet spring on base fit tightly.
In the utility model preferred embodiment, described band wheel assembly is connected with tension arms by bolt with dust cover.
In the utility model preferred embodiment, described bolt is connected with described tension arms by the bearing support boss on the right side of tension arms.
The beneficial effects of the utility model are: the utility model superimposed sheets spring formula stretcher, and this stretcher structure is simple, stable performance, firmly, and production and processing is simple, reduces cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the explosive view of a preferred embodiment of the utility model superimposed sheets spring formula stretcher.
In accompanying drawing, the mark of each parts is as follows: 1, base, and 2, sheet spring, 3, tension arms, 4, axle sleeve, 5, pivot, 6, bolt, 7, dust cover, 8, band wheel assembly.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 is the explosive view of a preferred embodiment of the utility model superimposed sheets spring formula stretcher.
A kind of superimposed sheets spring of the utility model formula stretcher, comprise: base 1, sheet spring 2, tension arms 3, axle sleeve 4, pivot 5, band wheel assembly 8 and dust cover 7, described sheet spring 2 is made up of the steel disc that three increase successively, the inwall of described base 1 is evenly provided with 4 sheet springs 2, one end, left side on described tension arms 3 is provided with a through hole, the arranged outside of described through hole has the central shaft outer wall of circular arc, described central shaft outer wall is evenly provided with 4 sheet springs 2 contrary with direction on base inner wall, base 1 and tension arms 3 and axle sleeve 4 are fixed together through tension arms 3 by described pivot 4, axle sleeve 4 is between pivot 5 and tension arms central shaft, pivot 5 is avoided directly to contact with tension arms central shaft, pivot 5 when efficiently reducing torsion, friction between tension arms central shaft, when tension arms 3 swings back and forth, the sheet spring 2 be close together mutually extruding produces elastic force, to suppress the amplitude of belt, one end, right side of described tension arms 3 is provided with band wheel assembly 8 and dust cover 7, sheet spring on described tension arms 32 a slice longer with the sheet spring 2 on base 1 fits tightly, when reversing, the longest a slice of each pack spring 2 is close together, due to the special construction of two pack spring 2 arranged opposite, tension arms 3 swing process produces moment of torsion and belt tension, when the tension arms 3 time slice spring 2 that twists extrudes mutually, produce elastic force, reverse larger, sheet spring 2 deformation is larger, reach the effect of varied tention.
Preferably, described band wheel assembly 8 is connected with tension arms 3 by bolt 6 with dust cover 7, and dust cover 7 can prevent dust from entering in the middle of stretcher Bearing with wheel.
Preferably, described bolt 6 is connected with described tension arms 3 by tension arms 3 right-hand axis bearing boss, connects and closely not easily loosens.
The utility model superimposed sheets spring formula stretcher, solving conventional tensioners can not the defect of varied tention and moment of torsion flexibly, and structure is simple, stable performance, firmly, and production and processing is simple, reduces cost.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
