A fan motor casing assembly convenient for injecting lubricating oil

Abstract

The invention discloses a fan motor shell assembly for facilitating injection of lubricating oil, which comprises a protective shell, a sliding bearing and a rotor, wherein the right side of the protective shell is connected with a cover body; a mounting bracket is mounted on the inner side of the cover body; the sliding bearing is mounted on the cover body; the rotor is mounted on the inner sideof the sliding bearing; the rotor and the cover body are mutually connected through the sliding bearing; a connecting ring is located on the inner side of the mounting backet; a pressing plate is mounted on the connecting ring; a capsule body is arranged in the gap between the pressing plate and the inner wall of the cover body; a liquid inlet is disposed above the capsule body; a dropper is connected to the capsule body; and the dropper is located on the inner side of the cover body. According to the fan motor shell assembly for facilitating injection of lubricating oil disclosed in the invention, disassembly of the motor shell in the case of applying the lubricating oil is avoided, the oil applying difficulty is further reduced, the occurrence of working failure after the motor shell iscompletely disassembled can be avoided, oil applying by a common user is facilitated, and spending money asking a professional for repairs can be avoided.

Description

technical field [0001] The invention relates to the technical field of multi-station progressive dies, in particular to a fan motor casing assembly which is convenient for injecting lubricating oil. Background technique [0002] The fan motor is the power source of the fan blades. The rotor of the fan motor is usually connected to the motor housing through bearings. The bearing of the fan motor is a special bearing. Due to the limitation of low friction and noise, it cannot use ball bearings, but Sliding bearings are manufactured by powder metallurgy technology, which is characterized by microporous oil-containing self-lubrication. The new products are lubricated by special technology. After a period of use, due to heating up, evaporation, dust blockage, etc., the rotation resistance increases and oil shortage occurs. Phenomenon, at this time, add lubricating oil in an appropriate amount, which can greatly alleviate the phenomenon of oil shortage; [0003] 1. The existing f...

Problems solved by technology

[0005] The purpose of the present invention is to provide a fan motor housing assembly that is convenient for injecting lubricating oil, so as to solve the problem that the existing fan motor housing proposed in the above background technology is inconvenient to lubricate the bearing assembly in the housing from the outside Most of the operation requires the motor shell to be disassembled for oiling. When the motor shell is disassembled, the internal circuit of the motor itself is easily damaged, and then it is prone to work failure. The traditional manual lubricating operation is mostly oiling The position is not accurate, and the oiling is uneven at the same time, it is difficult to improve the jamming phenomenon of the fan motor rotor, which easily affects the normal use of the fan
