Abstract
A one-way belt wheel of an automobile generator comprises a belt wheel casing, a mandrel, a one-way bearing, a dustproof cover, deep groove ball bearings and a mandrel sleeve and is characterized in that the belt wheel casing is in interference fit with the outer diameter of the one-way bearing, the outer diameter of the mandrel is tightly matched with the mandrel sleeve, the outer diameter of the mandrel sleeve serves as an inner rolling way of the one-way bearing, two sets of standard deep groove ball bearings are tightly matched with two ends of the mandrel, and the dustproof cover is installed at one end of the belt wheel casing. The one-way belt wheel has the advantages that a ball-rolling needle-ball structure is adopted, the axial shifting of the bearings is reduced, the high-speed operation performance of the bearings is improved, a middle mandrel assembly adopts split design, the problem that the concentricity is difficult to control in the manufacturing process is solved, the rotating flexibility of the bearings is improved, and the one-way belt wheel has the advantages of being reasonable in structure, simple and convenient to process and the like and meets the practical requirement of the automobile generator.
Description
(1) technical field
The utility model relates to a kind of one-way belt sheave, particularly a kind of automobile current generator one-way belt sheave.
(2) background technique
Along with the development of Hyundai Motor auto electronic and engine technique, the automobile generating acc power improve constantly lifting with rotating speed.Traditional automobile current generator belt pulley all is to move with the synchronization of motor car engine, thereby automobile is when starting together with the unlatching generator, transmission shaft is easily by the spring vibrations, or even oppositely jumping is revolved, the generation of this situation, except meeting reduces life of generator, belt life also can reduce, and produces noise simultaneously.For head it off, developed the generator one-way belt sheave, it mainly acts on and is: 1, reduce the fluctuation of front end train tension force, improve each part life of front end train; 2, reduce the fluctuation of speed of front end train, reduce the noise of front end train; 3, avoid reverse impact, effectively protect motor; 4, reduce the energy consumption that the generator counter-rotating causes, energy saving.
But existing single-way belt pulley of automobile generator complex structure, manufacture cost height can not applied on the general-utility car widely.
(3) model utility content
Have complex structure, shortcoming that manufacture cost is high in order to overcome existing automobile current generator belt pulley, the utility model provide a kind of rational in infrastructure, manufacturing process is simple, the single-way belt pulley of automobile generator that quality of product is more secure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of single-way belt pulley of automobile generator comprises belt wheel shell, mandrel, unilateral bearing, dust cover, deep groove ball bearing and core sleeve, it is characterized in that: belt wheel shell and unilateral bearing external diameter interference fit, outside diameter of mandrel and core sleeve's close-fitting, the external diameter of core sleeve is used as the interior raceway of unilateral bearing simultaneously, mandrel two ends close-fitting two cover standard deep groove ball bearings, belt wheel shell one end is equipped with dust cover.
The beneficial effects of the utility model are: the utility model adopts ball-needle roller-spherical structure, reduced the axial float of bearing, improved the high speed running performance of bearing, the intermediate core shaft assembly adopts the split design, avoid the unmanageable problem of concentricity in the course of working, improve the flexibility of revolution of bearing, had characteristics such as rational in infrastructure, that processing is easy, satisfied the practical requirement of automobile current generator belt pulley.
(4) description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: belt wheel shell 1, mandrel 2, unilateral bearing 3, dust cover 4, deep groove ball bearing 5 and core sleeve 6 form.
Fig. 2 is the unilateral bearing sectional view;
Among the figure: outer ring 3-1, needle roller 3-2, jump ring 3-3 and retainer 3-4 form.
Fig. 3 is the sectional view of mandrel and core sleeve.
(5) embodiment
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of single-way belt pulley of automobile generator, comprise that belt wheel shell 1 and unilateral bearing 3 are press-fitted, the sectional view of this unilateral bearing 3 is seen Fig. 2, mandrel 2 is press-fitted with core sleeve 6, its structural section figure sees Fig. 3, after these two-part assemble, be press-fitted deep groove ball bearing 5 at mandrel 2 two ends, mandrel 2 contacts with needle roller 3-2 by core sleeve (6), needle roller 3-2 by being contained in retainer 3-4 jump ring 3-3 and the irregular curved surface of outer ring 3-1 form unidirectional stop system, thereby form the generator one-way belt sheave of unidirectional rotation.Belt wheel shell 1 one ends are equipped with dust cover 4, and outer surface is coated with resin layer, and effectively preventing under operating conditions dirt and dabbling influences service behaviour.
This model utility has rational in infrastructure, and is easy for installation, and the characteristics of high life satisfy the requirement of automobile current generator belt pulley.
Claims (1)
1. single-way belt pulley of automobile generator, comprise that belt wheel shell (1), mandrel (2), unilateral bearing (3), dust cover (4), deep groove ball bearing (5) and core sleeve (6) is characterized in that: belt wheel shell (1) and unilateral bearing (3) external diameter interference fit, mandrel (2) external diameter and core sleeve (6) close-fitting, the external diameter of core sleeve (6) is used as the interior raceway of unilateral bearing (3) simultaneously, mandrel (2) two ends close-fitting two cover standard deep groove ball bearings (5), belt wheel shell one end is equipped with dust cover (4).
