, can there is axial float (play) location big, axial inaccurate, cause vibration noise big in ball bearing, behavior in service is poor, work equally
Make life-span low problem.
Utility model content
The purpose of this utility model is to provide a kind of axially location idle wheel for automobile engine simple, reliable.
A kind of idle wheel for automobile engine unit of the present utility model, including idle pulley, circlip, contact seal biserial
Angular contact ball bearing, sealing ring, bolt sleeve, hexagon socket head cap screw axle and dust cap.
On described idler interior bore, symmetry offers two locating slots, and described circlip is connected in locating slot；Institute
The contact seal double-row angular contact bal bearing stated is installed between two circlips；
Described bolt sleeve end face offers cannelure, and described sealing ring is arranged in the cannelure of bolt sleeve end face,
Bolt sleeve screws in hexagon socket head cap screw axle；
Described dust cap one end is buckled in the circumferential groove on described idle pulley installed surface, the end face phase of the other end and bearing
Contact；
Further, described idle pulley material is No. 45 steel and carries out surface granosealing；
Further, described circlip material is 65Mn steel and carries out surface granosealing；
Further, described bearing ring and the material of steel ball are GCr15 bearing steel, and retainer material is glass fibers
The nylon66 fiber that dimension strengthens；
Further, described sealing ring is O RunddichtringO, and material is nitrile rubber；
Further, described dust cap material is Q235A carbon structural steels and carries out surface electrophoretic process；
Further, it is interference fit between described bearing and idler interior bore, between hexagon socket head cap screw axle and bearing is
Interference fits.
This utility model has the advantage that
(1) by using contact seal low noise double-row angular contact bal bearing, the axial float of bearing is reduced, it is to avoid
The generation of unbalance loading situation, structure is compacter, in limited space, improve behavior in service and the service life of bearing；
(2) mode that axially positioned by bearing changes two-side elastic back-up ring structure into, improves the reliability of axially location, simplifies
The installation process of bearing also simplify idle pulley overall structure simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 1. idle pulley；2. circlip；3. double-row angular contact bal bearing；4. bolt sleeve；5. sealing ring；6. bolt axle；
7. dust cap.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
