Pressure bearing method at both ends of the rotor

Abstract

The invention relates to a method for pressing bearings at both ends of a rotor, which comprises the following sequential steps: stacking a plurality of upper bearing workpieces that need to be fixed on the upper end of the rotor workpiece and a plurality of lower bearing workpieces that need to be fixed on the lower end of the rotor workpiece respectively from top to bottom put; the rotor workpiece is axially and vertically positioned and the upper and lower ends of the rotor workpiece are exposed; the lowermost upper bearing workpiece among the plurality of upper bearing workpieces is moved to directly above the rotor workpiece, and the most lower bearing workpiece among the plurality of lower bearing workpieces is moved A lower bearing workpiece at the bottom is moved to directly below the rotor workpiece; the upper bearing workpiece is controlled to move down until the rotor workpiece contacts the lower bearing workpiece, and then the upper bearing workpiece is pressed down until the upper bearing workpiece and the lower bearing workpiece are pressed separately to both ends of the rotor workpiece; after removing the press-fitted rotor workpiece, the equipment resets to complete the press-fitting of the upper bearing workpiece and the lower bearing workpiece at both ends of the rotor workpiece. The invention has the characteristics of high press-fitting efficiency, good press-fitting quality and the like.

Description

technical field [0001] The invention relates to a method for pressing bearings at both ends of a rotor, and belongs to the technical field of bearing pressing. Background technique [0002] The existing motor rotor bearing pressing device has two types: vertical type and horizontal type. For the vertical bearing press-fitting device, the operator needs to manually put one bearing into the lower press-fitting tool, put the rotor into the press-fitting machine, put the other bearing into the upper end of the rotor shaft, and hold the rotor by hand to carry out the bearing at both ends. Press-fitting, this kind of press-fitting device, has low press-fitting process efficiency, large operation risk factor, and relatively high labor intensity of the operator. Although the horizontal bearing press machine reduces the operator's risk factor to a certain extent, when press-fitting, first press-fit one end of the rotor shaft, and then press-fit the other end of the shaft. This press...
