Description

A kind of waterproof machine

Technical field

The utility model relates to a kind of motor, the hermetically-sealed construction of especially relevant motor.

Background technology

Existing waterproof machine, there is poorly sealed problem in a plurality of junctions on shell, and moisture content easily infiltrates motor internal from the bearing pedestal of casing, causes waterproof machine electric leakage and early failure, has a strong impact on the safety and the useful life of waterproof machine.

Summary of the invention

The purpose of this utility model is to provide a kind of sealing tight, the waterproof machine that water-proof function is good.

In order to achieve the above object, the technical solution of the utility model is: a kind of waterproof machine, comprise rotor, stator, casing, end cap, bearing and lead-out wire, bearing is contained in respectively in the bearing pedestal of casing and end cap, the bearing that is contained in the casing bearing pedestal is a water-sealed bearing, be provided with sealing ring between the inner side end of the bearing pedestal of casing and the bearing inner side end, be provided with sealing ring between armature spindle periphery and the bearing hole wall.

After adopting said structure, because the bearing that is contained in the casing bearing pedestal is a water-sealed bearing, be provided with sealing ring between the inner side end of the bearing pedestal of casing and the bearing inner side end, be provided with sealing ring between armature spindle periphery and the bearing hole wall, therefore, tight in the sealing of the bearing pedestal place of casing, prevent that effectively moisture content from infiltrating from here, water-proof function is good, can prolong the useful life of waterproof machine greatly, and is safe and reliable.
