Abstract
The invention discloses a kind of reduced form automobile engine idle pulley structure, including neck bush, bearing and belt wheel, the bearing includes internal axle sleeve, ball and outer shaft, the outer shaft and belt wheel integrated setting, and the neck bush is in hollow cylindrical, its left end is provided with step surface, the internal axle sleeve is set on the step surface, and on internal axle sleeve, the ball is nested between internal axle sleeve and belt wheel the belt wheel empty set；Also include being used for belt wheel and the spacing stopping means of internal axle sleeve.Idle pulley structure of the invention simplifies outer shaft and belt wheel integrated setting to pulley structure, the problem for not only avoiding being difficult to determine bearing clearance and external bushing reduction during assembling, and can reduce procedure of processing.
Description
Technical field
The present invention relates to technical field of automobile engine, it is related to engine component, more particularly to a kind of reduced form automobile engine idle pulley structure.
Background technology
Idle pulley is conventional automobile engine component, existing automobile idle pulley structure generally comprises bearing, belt wheel and bushing composition, easily occur bearing clearance when the idle pulley of this structure is assembled and Outer Diameter of lining precision is difficult to the problem that determines, it is therefore necessary to which idle pulley structure is simplified with improve production efficiency.
The content of the invention
In view of this, the invention provides a kind of reduced form automobile engine idle pulley structure.
A kind of reduced form automobile engine idle pulley structure, including neck bush, bearing and belt wheel, the bearing includes internal axle sleeve, ball and outer shaft, the outer shaft and belt wheel integrated setting, and the neck bush is in hollow cylindrical, its left end is provided with step surface, the internal axle sleeve is set on the step surface, and on internal axle sleeve, the ball is nested between internal axle sleeve and belt wheel the belt wheel empty set；Also include being used for belt wheel and the spacing stopping means of internal axle sleeve.
Further, the ball number is multiple, is evenly distributed on the outer peripheral face of internal axle sleeve.
Further, the height of the internal axle sleeve is less than the height of neck bush step surface, and the stopping means is set in neck bush right-hand member, and it is highly more than the height of ball.
Further, the belt wheel outer wall is provided with v-depression.
The beneficial effects of the present invention are：
Idle pulley structure of the invention simplifies outer shaft and belt wheel integrated setting to pulley structure, the problem for not only avoiding being difficult to determine bearing clearance and external bushing reduction during assembling, and can reduce procedure of processing.
Brief description of the drawings
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, wherein：
Fig. 1 is reduced form automobile engine idle pulley structure chart of the present invention.
Specific embodiment
Hereinafter with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figure 1, the reduced form automobile engine idle pulley structure of the present embodiment, including neck bush 4, bearing and belt wheel 1, the bearing includes internal axle sleeve 6, ball 5 and outer shaft, the outer shaft and the integrated setting of belt wheel 1, and the neck bush 4 is in hollow cylindrical（With axis hole 3）, its left end is provided with step surface, and the internal axle sleeve 6 is set on the step surface, and on internal axle sleeve 6, the ball 5 is nested between internal axle sleeve 6 and belt wheel 1 empty set of the belt wheel 1；Also include being used for belt wheel 1 and the spacing stopping means of internal axle sleeve 6.In the present embodiment, the number of the ball 5 is multiple, is evenly distributed on the outer peripheral face of internal axle sleeve 6；The height of the internal axle sleeve 6 is less than the height of the step surface of neck bush 4, and the stopping means is set in the right-hand member of neck bush 4, and, highly more than the height of ball 5, the outer wall of the belt wheel 1 is provided with v-depression, and edge is provided with spacing preiection 2 for it.
Idle pulley structure of the invention simplifies outer shaft and belt wheel integrated setting to pulley structure, the problem for not only avoiding being difficult to determine bearing clearance and external bushing reduction during assembling, and can reduce procedure of processing.
What is finally illustrated is, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although by referring to the preferred embodiments of the present invention, invention has been described, but it will be understood by those within the art that, various changes can be made to it in the form and details, without departing from the spirit and scope of the present invention that appended claims are limited.
