Problems solved by technology

[0004] The purpose of the present invention is to provide a waterproof structure of the motor shaft, to solve the above-mentioned background technology. Not enough, it is necessary to customize the shaft with sufficient length. At the same time, the seal of the existing motor shaft is sealed by a simple sealed bearing itself. After long-term use, the sealing and waterproof effect will continue to decrease, and the shaft needs to be lubricated by lubricating oil when it rotates at high speed. The long-term rotation of the shaft keeps reducing the lubricating oil and consumes it very quickly, which leads to the problem of increasing the friction of the shaft

Abstract

The invention discloses a waterproof structure of a motor rotating shaft in the technical field of motor rotating shafts, which comprises a rotating shaft body, a waterproof bearing, a motor end cover, an oil seal and a sealing cover, and is characterized in that the waterproof bearing sleeves the outer side wall of the rotating shaft body, and the motor end cover sleeves the outer side wall of the waterproof bearing; the oil seal is clamped on the outer side wall of the rotating shaft body and located on the right side of the waterproof bearing, the sealing cover is connected to the right side of the outer side wall of the rotating shaft body in a sleeving mode and located on the right side of the oil seal, the waterproof structure of the motor rotating shaft is reasonable in structural design, a special rotating shaft does not need to be customized, and the use cost of the motor rotating shaft can be reduced; a plurality of layers of waterproof sealing devices can be arranged on the outer side of the rotating shaft, the sealing effect of the motor rotating shaft can be improved, a large amount of lubricating oil can be stored through the first oil storage ring and the second oil storage ring, the rotating shaft can be continuously lubricated, and therefore the service life of the rotating shaft can be prolonged.

Description

technical field [0001] The invention relates to the technical field of motor shafts, in particular to a waterproof structure for a motor shaft. Background technique [0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque, which is used as a power source for electrical appliances or various machinery. The output terminal is used for the power connection transmission of the motor. [0003] The existing motor shaft is used according to the specifications of the motor. Due to the installation position of the motor shaft during use, the length of the motor shaft is not enough, and a shaft of sufficient length needs to be customized, which leads to an increase in the cost of use. At the same time, the sealing of the existing motor shaft By simply sealing the bearing itself, the sealing and waterproofing effect will continue ...
