Rotor bearing sleeving press device

Abstract

Disclosed is a rotor bearing sleeving press device. The rotor bearing sleeving press device is used for pressing bearings on a spindle of a motor rotor in a sleeving mode. The rotor bearing sleeving press device comprises a first supporting base (8) and a second supporting base (10), wherein the first supporting base is installed on the left side of a base, and the second supporting base is installed on the right side of the base. A locating sleeve (5) is fixedly arranged on the first supporting base, a tappet rod (9) is arranged on the second supporting base, the tappet rod and a long through hole formed in the second supporting base are in sliding fit, and the locating sleeve and the tappet rod are coaxial. The maximum distance between the right side of the locating sleeve and the left side of the tappet rod is slightly larger than the length of the motor rotor spindle (2), and a hole of the locating sleeve is matched with a connecting portion (4) at the left end of the motor rotor spindle. A blind hole is formed in the left end of the tappet rod and matched with a connecting portion at the right end of the motor rotor spindle. The locating sleeve and the tappet rod are coaxial, and the right end of the tappet rod is connected with an oil cylinder (11). The rotor bearing sleeving press device has the advantages that due to the fact that the bearings at the two ends of the motor rotor spindle can be pressed in a sleeving mode at the same time, the working efficiency is improved; and due to the fact that the force borne by the ends of the bearings in the sleeving press process is uniform, the sleeving press quality is guaranteed.

Description

technical field [0001] The invention relates to a sleeve pressing device of a rotor bearing, which is used for pressing the bearing sleeve on the main shaft of the motor rotor. Background technique [0002] The structure of the motor rotor main shaft 2 is that the middle section of the motor rotor main shaft is an iron core part with an iron core, the two sides of the iron core part are bearing parts 3 with bearings, and the outer side of the bearing part is the connection part between the motor rotor main shaft and the outside 4, wherein the diameter of the core part is larger than the diameter of the bearing part, and the diameter of the bearing part is larger than the diameter of the connecting part. The method of pressing the bearing on the main shaft is to first press the bearing at one end of the main shaft, and then press the bearing at the other end of the main shaft. This kind of method is inefficient, and in order to improve the working efficiency of the bushing p...
