Motor bearing press mounting equipment

Abstract

The invention provides motor bearing press mounting equipment comprising the following units: a n-type support; a fixed seat fixed on the bottom plate of the support; a bearing pillar arranged above the fixed seat, wherein a boss structure is arranged on the top of the bearing pillar; an end cover sleeve capable of freely sliding up and down outside the bearing pillar, wherein a reset spring is sleeved on the lower section outside the end cover sleeve; a pressure mechanism arranged on the top plate, wherein the bottom of the pressure mechanism is connected with a vertical downward pressure rod; a control mechanism arranged on the top plate and connected with the pressure mechanism; a pressure sensor arranged on the bottom of the pressure rod and connected with a load displayer mounted on the top plate. The motor bearing press mounting equipment is simple and fast in operation, can effectively improve assembling efficiency, and the fitting tightness level between the motor bearing and the motor end cover can be determined according to the pressure, thus picking out unqualified products, and ensuring product quality.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to bearing press-fitting equipment in electric motor assembly. Background technique [0002] Motor bearings, also known as motor bearings or motor bearings, are special bearings specially used in motors or motors. The bearing used by the motor is a part that supports the shaft, it can guide the rotation of the shaft, and it can also bear the idling parts on the shaft. There are four types of bearings commonly used in motors, namely rolling bearings, sliding bearings, joint bearings and oil bearings. The most common motor bearings are rolling bearings, ie bearings with rolling elements. [0003] The installation methods of motor bearings include heat fit and press fit, in which heat fit is an installation method that uses thermal expansion to transform tight fit into loose fit by heating the motor bearing or bearing seat; press fit is to install the motor bearing by external force I...

AI Technical Summary

Problems solved by technology

In the press-fitting methods of the existing motor bearings, most of them are manually press-fitted. On the one hand, the workers are laborious, and on the other hand, it is difficult to detect the tightness of the motor bearing and the bearing seat. If the size of the bearing seat hole is too large or the bearing The problem that the size of the outer ring is too small is difficult to find manually, and the motor with this level of coordination will have certain safety hazards when used
