Embodiment Construction

[0015] Such as figure 1 The shown coupling structure of a motor rotor and a motor main shaft includes an inner tapered sleeve 6 arranged on the motor rotor 5 , and on the inner tapered sleeve 6 and at the rear end of the motor main shaft 10 there is a device for tightening the inner tapered sleeve 6 . The locking nut 7 fixed on the motor main shaft 10, the length of the locking nut 7 accounts for 1 / 4 to 1 / 2 of the length of the inner taper sleeve 6 . Preferably, the length of the locking nut 7 accounts for one-third of the length of the inner taper sleeve 6 . A washer is arranged between the lock nut 7 and the inner taper sleeve 6 . The front and rear ends of the motor housing 2 are respectively equipped with a front cover 1 and a rear cover 4, the lock nut 7 is connected with an encoder 8, and the encoder 8 is connected with an external driver. There is a stator 3 corresponding to the motor rotor 5 for starting the motor main shaft 10, and a gasket 9 is arranged between the...

Abstract

The invention discloses a connection structure between a motor stator and a motor main shaft. The connection structure includes a taper sleeve that is arranged on the motor stator; a lock nut, which is used for fastening the taper sleeve on the motor main shaft, is arranged on the taper sleeve and at a rear end of the motor main shaft; and the length of the lock nut accounts for a quarter of to half of the length of the taper sleeve. According to the invention, connection between a motor stator and a motor main shaft is fastened; and moreover, the motor stator and the motor main shaft can be easily and conveniently disassembled.

Description

technical field [0001] The invention relates to a connection structure, in particular to a connection structure between a motor rotor and a motor main shaft. Background technique [0002] The assembly of the motor rotor and the motor shaft must be considered in the design of the motor. Therefore, the connection of the motor rotor and the motor shaft has always been a concern in the field of motor manufacturing. The traditional motor rotor installation method is realized by using only interference fit between the motor rotor and the motor shaft. The disadvantage of this method is: on the one hand, the use of this connection method makes it very inconvenient to disassemble the motor rotor and the motor shaft; Technical experience is required. For actual use has brought very big inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a coupling structure between a m...
