Abstract

The invention discloses a motor rotating shaft convenient for connection. The motor rotating shaft comprises a rotating shaft, a pull rod, a top cover and two joint keys. The external contour of one end of the rotating shaft is provided with threads. The rotating shaft is provided with a through hole. The two joint keys are respectively arranged in the through hole. The cross section of the through hole is rectangular. A cavity is arranged in the middle of the rotating shaft. The pull rod is arranged in the cavity which is connected with the through hole. One end of the pull rod is connected with the two joint keys, and the other end is connected with the top cover. The internal side of the top cover is provided with threads. According to the motor rotating shaft convenient for connection, the joint keys, the top cover and the pull rod are arranged so that pop-up and retracting of the joint keys can be conveniently controlled; and each joint key is provided with a fixed hole, each groove is internally provided with a telescopic rod, and each telescopic rod is corresponding to each positioning hole in a one-to-one way so that stability and safety can be enhanced.

Description

technical field [0001] The invention relates to a motor, and mainly relates to a rotating shaft of the motor. Background technique [0002] The motor shaft is an important part of the motor. Most of the connection between the motor shaft and various components adopts interference fit, clearance fit or transition fit; most of these fits use the principle of thermal expansion and contraction, and each component is directly placed on the motor shaft. In this way, the direct sleeve on the motor shaft may fall off after a long time of high-speed rotation, causing the motor to fail to operate or causing safety problems. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a motor shaft that is easy to connect, including a shaft, a pull rod, a top cover, and two coupling keys; the outer contour of one end of the shaft is provided with threads; the shaft is provided with through holes, two The two connecting keys are res...
