Description
Technical field
The utility model relates to a kind of Idle wheel, particularly relates to a kind of mounting bracket of Idle wheel.
Background technique
Tension pulley is very important parts in belt drive system, bearing up pulley is primarily of compositions such as stationary housing, tension arms, wheel body, torsion spring, rolling bearing and spring axle sleeves, owing to can relax after belt Long-Time Service, Idle wheel be then be responsible for giving the stable tension force of belt and can be different according to belt tightness, automatic adjustment tension force, makes transmission system stability and safety reliable.No matter be new belt or old belt, if do not have Idle wheel, lax belt can skid and lose gearing.Not only widely used V belt translation in contemporary motor car engine and driven the annexes such as generator, air condition compressor, fan, the camshaft connecting needs and bent axle maintenance strict phase relation also uses belt wheel transmission.Along with the requirement of automobile to combination property improves constantly, the middle generator of motor front-end wheel system, air condition compressor, the layout of tension pulley and support thereof, the space taken is larger, arranges and also become more complicated very difficult in limited engine compartment space.
Model utility content
The utility model provides a kind of belt pulley tensioner apparatus, and this device is arranged on the shell of motor, eliminates the rack arrangement space of Idle wheel, engine wheel system is arranged more convenient, simultaneously and its dismounting is more convenient.
The utility model solves the technological scheme that its technical problem adopts: a kind of tension pulley, comprises positioning adapter, mounting bracket, torsion spring, tension arms, wheel body, back-up ring, positioning seal ring, latch forms, and wheel body is arranged on tension arms by jack shaft, and one end of wheel body is provided with back-up ring; Tension arms and positioning adapter fit together in an interference fit; Torsion spring is arranged between mounting bracket and tension arms, and the jump ring starting point of torsion spring is stuck on mounting bracket, and jump ring end is stuck on tension arms.
Further, mounting bracket is provided with one or several draw-in groove, and positioning adapter is provided with one or the several positioning block corresponding with draw-in groove.
Further, the motion amplitude of the positioning block on positioning adapter on mounting bracket is 30 ° ~ 60 °.
The beneficial effects of the utility model are: the utility model structure is simple, and reliable performance, and the number of spare parts decreasing Idle wheel, reduce manufacture cost, is easy to accomplish scale production; In addition, this Idle wheel can be directly installed on generator by bolt, eliminates the support of Idle wheel, annex on motor is installed more compact convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is plan view of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along A-A line;
Fig. 3 is rear view of the present utility model;
Wherein: 1. positioning adapter; 11. positioning blocks; 2. mounting bracket; 21. draw-in grooves; 22. plug housings; 221. hinge last; 3. torsion spring; 31. jump ring starting points; 32. jump ring ends; 4. tension arms; 5. wheel body, 6. back-up ring; 7. positioning seal ring; 8. latch.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of tension pulley, comprises positioning adapter 1, mounting bracket 2, torsion spring 3, tension arms 4, wheel body 5, back-up ring 6, positioning seal ring 7, and latch 8 forms, and wheel body 5 is arranged on tension arms 4 by jack shaft, and one end of wheel body is provided with back-up ring 6; Tension arms 4 and positioning adapter 1 fit together in an interference fit; The positioning seal ring 7 be made up of abrasive rubber is provided with, to increase the damping of Idle wheel between positioning adapter 1 and mounting bracket 2; Torsion spring 3 is arranged between mounting bracket 2 and tension arms 4, and the jump ring starting point 31 of torsion spring 3 is stuck on mounting bracket 2, and jump ring end 32 is stuck on tension arms 4.
Further, its mounting bracket 2 is provided with one or several draw-in groove 21, and positioning adapter 1 is provided with one or the several positioning block 11 corresponding with draw-in groove 21.
Further, the radian of draw-in groove 21 can require to set according to the tension force of different engine wheel system, and the motion amplitude of the positioning block 11 on positioning adapter 1 on mounting bracket 2 is 30 ° ~ 60 °.
Working principle of the present utility model: after Idle wheel Overall Group installs into, first mounting bracket 2 is fixed, tension arms 4 is rotated again with a tension device, after positioning block 11 on lining 1 to be positioned rotates to draw-in groove 21 limit in mounting bracket 2, the relative position of tension arms 4 and mounting bracket 2, through the hinge last 221 on the hole be set on tension arms 4 and plug housing 22, is fixed by latch 8.After Idle wheel after pretension delivers to motor assembling product line, first with bolt, mounting bracket 2 is fixed on generator, wheel body 5 is made to be on same level line with the wheel body of generator, after loading onto belt, latch 8 is extracted, tension arms 4 by belt tension, ensure that the smooth transfer of power under the effect of torsion spring 3.
