High-precision motor output shaft starting gear press fitting device

Abstract

The objective of the invention is to provide a high-precision motor output shaft starting gear press fitting device capable of implementing starting gear high-precision press fitting. In order to achieve the purpose, the device comprises a first sleeve, a second sleeve, a spacing block and a pressing head. The first sleeve and the second sleeve both have penetrating grooves penetrating up and down, the spacing block and the first sleeve are both used to sleeve the outer portion of a motor shaft, the first sleeve is supported on the spacing block, the second sleeve sleeves the outer portions ofthe spacing block and the first sleeve to coaxially arrange the second sleeve, the spacing block and the first sleeve, when a starting gear is put in the first sleeve, the outer wall of the circumference of the starting gear is in clearance fit with the inner wall of the circumference of the first sleeve, and when the spacing block sleeves the motor shaft, the inner wall of the circumference of the spacing block is in clearance fit with the outer wall of the circumference of the motor shaft to coaxially arrange the spacing block and the motor shaft.

Description

technical field [0001] The invention relates to a press-fitting device for a starting gear of a motor output shaft. Background technique [0002] After completing the internal assembly of the motor, some motors need to press-fit the starting gear at the output shaft end of the motor. In the prior art, the motor is vertically arranged and the motor shaft is vertically arranged, the starting gear is placed outside the upper end of the motor shaft, and then the starting gear is pressed on the motor shaft by a press, and the pressing stroke of the press is used to ensure It is difficult to ensure the position of the starting gear on the motor shaft in the press-fit position, and it is difficult to guarantee the coaxiality of the starting gear and the motor shaft. Among them, due to processing problems, there are errors in the axial end surface of the motor end cover, and it is difficult to ensure high-precision verticality between the motor end cover and the motor shaft.
