Dirt, the inclination angle of the lateral surface is α, and α angles are preferably 10 degree, and in idle pulley rotation process, the dust into the dedusting slot exists
Idle pulley preferably is skidded off along lateral surface under the action of centrifugal movement, forms the preliminary dust-proof and dedusting of idle pulley.
As the preferred of this practicality, the medial surface is connected with the lateral surface by arc groove.
The arc groove can be used for grade dirt and dedusting and the mellow and full transition of the lateral surface and preferably be beneficial to remove as a result,
Dirt.
As the preferred of this practicality, the outer rim of two housing flange is in same cylindrical surface.
As the preferred of this practicality, the dustproof cover is symmetrical arranged.
As the preferred of this practicality, bearing is further included, the bearing is detachably connected with the housing by hole with baffle ring.
As the preferred of this practicality, the dome number of units amount is 2, and the width of symmetrically arranged left dome platform is more than the right side
The width of dome platform, convenient for the installation and fixation of the bearing while fool-proof design.
The utility model has the advantages that：
The utility model designs a kind of dustproof automotive idle pulley, provides that three-level is dust-proof and the effect of dedusting, by dustproof cover and
The cooperation of dedusting slot and idle pulley housing so that the dust into idle pulley is discharged or accumulated in the storage dirt portion of dustproof cover, protection
The service life of bearing convenient for dedusting, provides idle pulley and is preferably driven, and reduces the fuel oil loss of automobile, preferably realizes turning for energy
It changes, is finally reached the effect of energy-saving and emission-reduction.
