State the first counterbore, the second counterbore, the 3rd counterbore, the bearing gradually to successively decrease provided with diameter with one heart successively from left to right in end cap body
Bore, shaft outlet hole, the end cap body right side are provided with the 4th counterbore with one heart, and the 3rd counterbore internal clearance, which coordinates, is provided with first
Deadening felt, the second counterbore internal clearance, which coordinates, is provided with silicagel pad, and the first counterbore internal clearance, which coordinates, is provided with rubber blanket, described
First counterbore bottom surface is provided with annular groove with one heart, and the rubber blanket right side is provided with the bulge loop with annular groove interference fit, institute
State in the 4th counterbore from left to right that gap coordinates provided with the second deadening felt, lip-type packing successively.
The rubber blanket, silicagel pad, the first deadening felt, the second deadening felt are annular, the rubber blanket, silicagel pad,
First deadening felt, the internal diameter of the second deadening felt are equal and are more than shaft diameter.
The rubber mat thickness is equal to the depth of the first counterbore, and the thickness of silicagel pad is equal to the depth of the second counterbore, and first
The thickness of deadening felt is equal to the depth of the 3rd counterbore.
The 4th counterbore depth is the second deadening felt thickness and lip-type packing thickness sum.
The beneficial effects of the invention are as follows：The present invention is simple and reasonable, is distinguished by the motor bearings both sides in end cap
Provided with the first deadening felt, the second deadening felt, noise caused by motor bearings when can be effectively isolated motor operation, noise is reduced
Pollution, while silicagel pad and rubber blanket are provided with the outside of the first deadening felt, lip-type packing is provided with the outside of the second deadening felt, significantly
Anti-dust performance is improved, improves the service life of motor bearings, it is practical, it is worthy to be popularized.
