Device for automatically lubricating and reducing noise in small and special electric machine

Abstract

The invention relates to the technical field of small and special electric machine lubrication, and discloses a small and special electric machine internal automatic lubrication and noise reduction device, which comprises a lubrication device main body, a rotating disc is rotatably mounted in the lubrication device main body, a through hole is formed in the outer wall of the rotating disc, and a water tank is welded in the rotating disc. And a noise reduction mechanism is welded in the lubricating equipment main body. A water solution in a water tank is evaporated into water vapor which enters an air cylinder in a rotating wheel, the air cylinder stretches out, two stop rods drive the rotating wheel to deflect, and due to the fact that a protruding arc block on the outer wall of the rotating wheel is located on one side of a push rod at the beginning, after the rotating wheel deflects, the push rod is pulled away from the circle center of a rotating disc under the action of an internal magnet; the push rod moves to drive the sliding rod to move towards the outer side of the circle center, the sound absorption plate can be far away from the rotating disc, and the effects that after the temperature rises, friction between the rotating disc and the sound absorption plate is avoided, the sound absorption plate is damaged, and the service life of the sound absorption plate is prolonged are achieved.

Description

technical field [0001] The invention relates to the technical field of micro-motor lubrication, in particular to a device for automatically lubricating the interior of a micro-motor and reducing noise. Background technique [0002] The full name of micro-special motor is micro-special motor, which refers to micro-special motor with diameter less than 16mm or rated power or special performance and special purpose. Micromotors are often used in control systems to realize functions such as detection, calculation, amplification, execution or conversion of electromechanical signals or energy. [0003] During the use of the micro motor, when the degree of lubrication of the internal parts is insufficient, the internal temperature of the motor will rise, which is not conducive to the long-term operation of the micro motor, and the noise reduction equipment inside the micro motor will absorb sound during use. The constant frictional contact between the board and the internal rotati...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for automatically lubricating and reducing noise inside the micro-motor, which is capable of automatically lubricating the rotating disc when the internal temperature of the rotating disc rises, and when the degree of lubrication of the rotating disc is insufficient The advantage of avoiding the contact between the sound-absorbing board and the rotating disc and ensuring the service life of the sound-absorbing board is to solve the problem that during the use of the micro-motor, when the lubrication degree of the internal parts is not enough, it will cause the internal temperature of the motor to rise, which is not conducive to the micro-motor. The long-term operation of the special motor, and the internal noise reduction equipment of the micro-motor are in use, the sound-absorbing board will be in constant friction contact with the internal rotating disk, which will cause damage to the sound-absorbing board, which will cause the problem of noise from the micro-motor
