Abstract

The utility model discloses a compact tension pulley for an engine. The compact tension pulley includes a belt wheel, a tension arm and a base, wherein the belt wheel and the tension arm are arranged on the base in a matching manner; a central shaft is arranged on the tension arm; a spring is arranged between the base and the tension arm in a matching manner; a supporting surface is arranged on the tension arm; a plurality of raised supporting structures are arranged on the supporting surface; the supporting structure is contacted with the spring; a rear end gasket is arranged on the base in a matching manner; and the rear end gasket is matched with the central shaft. Through adopting the manner, the compact tension pulley for the engine has the advantages of low manufacturing cost, compact structure, lighter weight, saved installation space and adaptation to narrow installation space of the engine.

Description

Motor is used compact Idle wheel

Technical field

The utility model relates to technical field of engines, particularly relates to a kind of motor and uses compact Idle wheel.

Background technique

Along with the speed of automobile develops to lightweight to the weight of speed up, vehicle body, vibration noise problem day is outstanding, and people are to the also more and more strictness of requirement of vibration and noise.After automobile used a period of time, the belt tension decay was the main cause of accessory belt abnormal sound.The fixed tensioning structure, is replaced by the auto-tensioning structure in the tension structure design of leading portion belt because of not compensating belt extension and reasons such as wearing and tearing and preset high tension in use gradually.The auto-tensioning wheel can effectively address the above problem, but volume is bigger mostly, can not adapt to narrow installing space.

The model utility content

The technical problem that the utility model mainly solves provides that a kind of cost of production is low, compact structure, weight motor light, that practice thrift installing space are used compact Idle wheel, can adapt to the narrow installing space of motor.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of motor to use compact Idle wheel, comprising: belt wheel, tension arms and base; Said belt wheel and tension arms are equipped with on base; Have a central shaft on the said tension arms, be equipped with spring between said base and the tension arms, on the said tension arms supporting surface is set; Have a plurality of supporting structures that are convex on the said supporting surface; Said supporting structure contacts with spring, is equipped with the rear end pad on the said base, and said rear end pad matches with central shaft.

In preferred embodiment of the utility model, the centre distance of said central shaft and belt wheel is smaller or equal to 25 millimeters.

In preferred embodiment of the utility model, said supporting structure quantity is 3.

In preferred embodiment of the utility model, said supporting surface forms the 3 stops surface of contact through 3 supporting structures.

In preferred embodiment of the utility model, said rear end pad is that steel material is processed.

In preferred embodiment of the utility model, said belt wheel is connected through the M8 bolt with tension arms.

The beneficial effect of the utility model is: the utility model motor is low with compact Idle wheel cost of production, compact structure, weight are light, practice thrift installing space can adapt to the narrow installing space of motor.

Description of drawings

Fig. 1 is the structural representation of the utility model motor with compact Idle wheel one preferred embodiment;

Fig. 2 be shown in motor with the sectional view of compact Idle wheel;

Fig. 3 be shown in motor with the partial structurtes schematic representation of compact Idle wheel;

Fig. 4 is the plan view of Fig. 3;

The mark of each parts is following in the accompanying drawing: 1, belt wheel, 2, tension arms, 3, base, 4, central shaft, 5, spring, 6, supporting surface, 7, supporting structure, 8, the rear end pad, 9, the M8 bolt.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.

See also Fig. 1 and Fig. 4, a kind of motor is used compact Idle wheel, comprising: belt wheel 1, tension arms 2 and base 3; Said belt wheel 1 is equipped with on base 3 with tension arms 2; Have a central shaft 4 on the said tension arms 2, be equipped with spring 5 between said base 3 and the tension arms 2, on the said tension arms 2 supporting surface 6 is set; Have a plurality of supporting structures 7 that are convex on the said supporting surface 6; Said supporting structure 7 contacts with spring 5, is equipped with rear end pad 8 on the said base 3, and said rear end pad 8 matches with central shaft 4.

In addition, the centre distance of said central shaft 4 and belt wheel 1 is smaller or equal to 25 millimeters, and central shaft 4 is a brachium with the centre distance of belt wheel 1, shortens brachium and makes compact structure, and reduced the Idle wheel quality, has adapted to the narrow installing space of motor.

In addition, said supporting structure 7 quantity are 3.

In addition; Said supporting surface 6 forms the 3 stops surface of contact through 3 supporting structures 7; Can change the axial reaction force of 5 pairs of tension armss of spring according to the height that laboratory data is adjusted each supporting structure 7; Thereby balance spring axial force effectively helps improving the parallelism parameter of stretching wheel assembly.

In addition, said rear end pad 8 is processed for steel material, and the rear end pad of processing through steel material 8 has solved the drawback of the stressed mutability of common aluminum alloy pad, and raw material obtain on market more easily, and purchase cost is lower.

In addition, said belt wheel 1 is connected through M8 bolt 9 with tension arms 2, adopts M8 tap bolt head as the Point of Strength of pulling arm, cooperate the long structural feature of galianconism to satisfy installation dismounting needs, and cost has obtained optimization.

Be different from existing technology, the utility model new work engine is low with compact Idle wheel cost of production, compact structure, weight are light, practice thrift installing space can adapt to the narrow installing space of motor.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
