Mounting device for upper bearing of motor rotor

Abstract

The invention discloses a mounting device for the upper bearing of a motor rotor. The mounting device comprises a working frame and the rotor with a rotating shaft, wherein the working frame is composed of a radial adjusting rod and axial adjusting rods perpendicular to the radial adjusting rod; a positioning sleeve is arranged on the radial adjusting rod in the axial direction; the rotating shaft on the rotor can move in the positioning sleeve; the internal diameter of the positioning sleeve is not smaller than that of the bearing inner ring of the bearing and not greater than the external diameter of the bearing inner ring of the bearing; a mounting support capable of moving along the axial adjusting rods is arranged on the axial adjusting rods; a rotating shaft pressing mechanism is arranged on the mounting support; a limiting mechanism for limiting the mounting support is also arranged on the axial adjusting rods. After the bearing is placed at one end of the upper rotating shaft of the rotor, the end of the upper rotating shaft, where the bearing is placed, is aligned with the positioning sleeve, the bearing inner ring of the bearing is propped against the positioning sleeve, the other end of the rotating shaft, where no bearing is placed, is propped against the rotating shaft pressing mechanism, and the rotating shaft pressing mechanism and the positioning sleeve are opposite to each other to mount the bearing onto the rotating shaft in a sleeving way. The mounting device has the advantage of high working efficiency.

Description

Technical field [0001] The invention relates to the field of installation tools, in particular to an installation device for a bearing on a motor rotor. Background technique [0002] The motor is mainly composed of a rotor with a rotating shaft and a stator. Bearings need to be installed on the rotating shaft of the rotor. The current method of installing the bearings on the rotating shaft is: sleeve the bearing on the outer end of the rotating shaft on the rotor, and then use a small hammer, copper rod, etc. The tool strikes the bearing inner ring of the bearing in contact with the rotating shaft symmetrically until the bearing is completely sleeved on the rotating shaft of the rotor. The disadvantages of this installation method are: the labor intensity of workers is high, the installation efficiency is low, and the force acting on each part of the inner ring of the bearing cannot be guaranteed to be the same when manually knocking, which will easily cause the inner ring of the...
