Description
Technical field
The utility model relates to belt tensioner field, particularly relates to a kind of expansion tightening wheel system.
Background technique
Expansion tightening wheel is primarily of compositions such as stationary housing, tension arms, wheel body, torsion spring, rolling bearing and spring axle sleeves, and tightness that can be different according to belt, adjusts tension force automatically, makes transmission system stability and safety reliable.Expansion tightening wheel is an easily damaged parts of the Component such as automobile, and belt has been grown with the time and has easily been stretched, and some expansion tightening wheels can regulate the tension force of belt automatically, and had expansion tightening wheel belt to run in addition more steady, noise is little, and can prevent from skidding.Expansion tightening wheel in actual use in order to keep suitable belt tension power, avoid belt slippage, compensate belt wearing and tearing and aging after the elongation that causes, need certain moment of torsion.When belt tightening wheel operates, the belt of motion may evoke vibration in expansion tightening wheel, can cause belt and expansion tightening wheel premature abrasion.
Model utility content
The utility model, in order to overcome deficiency of the prior art, provides a kind of expansion tightening wheel system, carries out tensioner for realizing to belt, prevents belt from transmission process, occurring wearing and tearing, elongate, ensures the smooth running of transmission device.
The utility model is achieved through the following technical solutions:
A kind of expansion tightening wheel system, comprise upper saw pulley, expansion tightening wheel, be characterized in that described expansion tightening wheel system also comprises column, spreader, described upper saw pulley comprises upper saw pulley A, upper saw pulley B, described expansion tightening wheel is fixed on the fixed plate that is fixedly connected with column, and described fixed plate is provided with groove, and expansion tightening wheel can slide up and down along groove, described expansion tightening wheel is connected by spring with between slide block, and described slide block is fixed in groove.
As optimal technical scheme of the present utility model, described slide block is fixed by screws in groove.
As optimal technical scheme of the present utility model, described upper saw pulley A is fixed on column by support A, and described upper saw pulley B is fixed on spreader by support B.
Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of expansion tightening wheel system, carry out tensioner for realizing to belt, prevent belt from transmission process, occurring wearing and tearing, elongate, ensure the smooth running of transmission device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, belt; 2, upper saw pulley A; 3, support A; 4, column; 5, spreader; 6, upper saw pulley B; 7, support B; 8, spring; 9, slide block; 10, groove; 11, fixed plate; 12, expansion tightening wheel.
Embodiment

Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of expansion tightening wheel system, comprise upper saw pulley, expansion tightening wheel 12, be characterized in that described expansion tightening wheel 12 system also comprises column 4, spreader 5, described upper saw pulley comprises upper saw pulley A2, upper saw pulley B6, described expansion tightening wheel 12 is fixed on the fixed plate 11 that is fixedly connected with column 4, and described fixed plate 11 is provided with groove 10, and expansion tightening wheel 12 can slide up and down along groove 10, described expansion tightening wheel 12 is connected by spring 8 with between slide block 9, and described slide block 9 is fixed in groove 10.
Described slide block 9 is fixed by screws in groove 10.
Described upper saw pulley A2 is fixed on column 4 by support A3, and described upper saw pulley B6 is fixed on spreader 5 by support B7.
When carrying out tensioner to belt 1, belt 1 being assembled on upper saw pulley A2, upper saw pulley B6, expansion tightening wheel 12, then by the tension force of the position regulation belt 1 of moving slider 9, then fixing slide block 9 and groove 10.The spring 8 be arranged between slide block 9 and expansion tightening wheel 12 makes expansion tightening wheel 12 adapt to the operating vibrations of belt 1.
The utility model provides a kind of expansion tightening wheel system, carries out tensioner for realizing to belt 1, prevents belt 1 from transmission process, occurring wearing and tearing, elongate, ensures the smooth running of transmission device.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
