When the driven by motor belt pulley rotated, sealing cover and main shaft were motionless, and sealing gasket rotates with belt pulley.Described labyrinth sealing not only can effectively prevent the intrusion of dust, and the rotation of sealing gasket can throw away drenching the water of going into.
In the sealing configuration in above-mentioned automobile cooling transmission device, the inner side surface of described sealing cover and main shaft are drive fits.
In the sealing configuration in above-mentioned automobile cooling transmission device, the material of described sealing gasket is plastics; Described sealing cover is made up of interior ring and outer shroud two-part, and ring is made by metallic material in it, and its outer shroud is made of plastics, and both drive fits connect.Not only cost is lower for sealing gasket of this sealing configuration and sealing cover employing plastics, and easy to manufacture, precision easily realizes, and reduced friction noise and the frictional heat that produces in the working procedure.
In the sealing configuration in above-mentioned automobile cooling transmission device, described sealing cover is pressed on the inner ring of bearing by the shaft shoulder of main shaft.
In the sealing configuration in above-mentioned automobile cooling transmission device, be connected by screw between described sealing gasket and the belt pulley.
In the sealing configuration in above-mentioned automobile cooling transmission device, described sealing configuration also comprises the end cap that is fixed on the belt pulley outer end.End cap in this device can prevent effectively that dust, muddy water from entering the bearing of belt pulley outer end.
Compared with prior art, advantage of the present utility model is: sealing gasket in this sealing configuration and sealing cover adopt the plastics manufacturing and constitute labyrinth sealing, and it is dustproof, water-proof performance is good, the generation of noise and the frictional heat of can effectively reducing friction.
In addition, adopted two kinds of parts simple in structure of sealing gasket and sealing cover in the utility model, manufacturing and loading and unloading are all very convenient, and cost is lower.Use this seal arrangement can prevent more effectively that dust, muddy water from entering bearing, guaranteed the normal operation of bearing, improve bearing life.
