Abstract
The utility model relates to a motor waterproof dustproof structure, in particular to a waterproof dustproof hood and a motor utilizing the same. An inward-drawing shaft sleeve is formed at the middle of the waterproof dustproof hood, and a cavity is formed outside the shaft sleeve. The waterproof dustproof hood shaft sleeve is sleeved on a motor shaft and is tightly matched with the motor shaft, and a bearing chamber on a motor end cover is arranged inside the cavity and is covered by the waterproof dustproof hood. The shaft sleeve extends into the bearing chamber through a shaft extension hole of the motor end cover. By adopting the motor of the structure, water and dust cannot enter the motor along with the motor shaft and is free from being leaked into the motor through the gap between the motor shaft and the shaft extension hole on the end cover, thereby having good tightness, easy installation, low cost and easy mass production.
Description
Technical field
The utility model relates to the motor waterproof and dustproof structure, is specifically related to the water proof and dust proof cover and uses the motor of this water proof and dust proof cover.
Background technology
Traditional motor, gapped between machine shaft and end cap, poor sealing are infiltrated in the motor in order to prevent dust or water, influence the work of motor, usually use rubber washer as the water-tight dustproof construction, but rubber washer is of long duration aging easily, causes into water.The labyrinth structure of employing or other more complicated hermetically-sealed constructions are also arranged, and complex manufacturing process is installed also very inconvenience, water proof and dust proof effect imperfection.
The utility model content
The purpose of this utility model provides a kind of water proof and dust proof cover, and it is simple in structure, makes and installs easily, and cost is low.
Another purpose of the present utility model provides a kind of motor of using above-mentioned water proof and dust proof cover, and its water proof and dust proof is effective, installs easily, and cost is low.
The technical solution of the utility model is as follows:
A kind of water proof and dust proof cover, the axle sleeve of formation in-draw in the middle of the water proof and dust proof cover forms cavity in the axle sleeve outside.
Above-mentioned described water proof and dust proof cover is made of plastic.
Water proof and dust proof cover of the present utility model has following advantage: simple in structure, install easily, and with low cost, easily form and produce in batches.
A kind of motor of using above-mentioned water proof and dust proof cover, described water proof and dust proof cover axle sleeve are sleeved on the motor shaft and with motor shaft and form tight fit, and the bearing chamber on the described electric motor end cap places the cavity the inside to be covered by the water proof and dust proof cover.
Above-mentioned described axle sleeve extend into the bearing chamber the inside from the shaft extension hole of electric motor end cap.
Be recessed to form groove on the above-mentioned described bearing chamber outside, the end cap end face, the lateral wall bottom of water proof and dust proof cover is embedded in the groove.
The motor of use water proof and dust proof cover of the present utility model has following advantage: water and dirt can not infiltrate motor along motor shaft, the motor that can not bleed from the gap between the shaft extension hole on motor shaft and the end cap, and good airproof performance, easy for installation, can reduce product cost.
