Abstract

The invention discloses a waterproof and air-permeable film rotor assembly. The waterproof and air-permeable film rotor assembly comprises a rotor and a stator, an annular gap is formed between the rotor and the stator, the inner diameter D1 of the exterior of the annular gap is greater than the inner diameter D2 of the interior of the annular gap. The waterproof and air-permeable film rotor assembly has the beneficial effects that when a machine works, a rotating shaft is in a horizontal state generally, rainwater entering the annular gap is converged to the lowest position of the annular gapunder the effect of the gravity, and then flows out of the machine, and the waterproof and air-permeable film effects are achieved.

Description

technical field [0001] The invention relates to a rotor assembly, in particular to a waterproof and air-permeable rotor assembly. Background technique [0002] In rotating machinery, there are generally a rotor part and a stator part. The rotor part is supported on the stator by bearings. There is a gap between the rotor part and the stator part. At the same time, it is convenient for ventilation inside and outside the machine. The gap is often not waterproof. , rainwater seeps into the machine from the gap, causing malfunction. Especially for the motor, when the motor is used in the field, the gap between the output shaft and the stator part often causes rainwater to enter the motor, causing motor failure. Contents of the invention [0003] The object of the present invention is to provide a waterproof and air-permeable rotor assembly in view of the gap between the rotor and the stator of the current rotating machinery. [0004] In order to realize the above-mentioned p...
