An automatic assembly device for inner and outer rings of high-speed bearings

Abstract

The invention relates to an automatic assembly device for an inner ring and an outer ring of a high-speed bearing, and belongs to bearing processing equipment. The automatic assembly device comprises a workbench, a heating mechanism and a clamp, wherein heating mechanism comprises a manipulator bracket, a heat conduction plate, a heating element, insulation boards and a manipulator, slide grooves are formed in the manipulator bracket, the manipulator can move in the slide grooves, grooves are formed in one end of the manipulator, the manipulator is electrically connected with an external control device, the heat conduction plate is annular, the heating element is sleeved on the heat conduction plate, the two insulation boards are arranged on the outer wall of the heat conduction plate and extend into the grooves to be connected with the manipulator, the clamp is positioned right below the heat conduction plate, a boss is formed at the upper part of the clamp in a narrowing way, a step face is formed between the boss and the clamp, an outer ring and a retainer with rolling elements are arranged on the step face, the outer ring is sleeved on the boss, and positioned on the upper inner side in the height direction of the retainer. According to the device, assembly is realized by virtue of self weight of an inner ring, the frictional wear of a bearing during the assembly process is alleviated, the temperature control precision is high, the assembly efficiency is high, the pollution is slight, and the service life of the device is long.

Description

technical field [0001] The invention belongs to the technical field of bearing processing equipment, and in particular relates to an automatic assembly device for inner and outer rings of a high-speed bearing, which can be used for the assembly of high-precision bearings. Background technique [0002] Bearing is an important basic component of contemporary mechanical equipment, which plays a role in fixing and reducing the friction coefficient of load in the process of mechanical transmission. The precision, performance, life and reliability of the bearing play a decisive role in the precision, performance, life and reliability of the main engine. With the progress and development of the current society and the continuous improvement of the degree of mechanization, the application of bearings is becoming more and more extensive. High-speed bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The function of the inner ring is to co...

Problems solved by technology

This method consumes a lot of energy, takes a long time to heat up, requires manual work, and cannot realize full automation of assembly. The efficiency of heating and assembly is not high, and the operation is dangerous and polluted. External force can complete the assembly, which will also affect the service life of the bearing

Most of the current thermal expansion methods use the principle of electromagnetic heating for assembly. Although this method has improved compared with the traditional assembly method, there are still deficiencies, such as the uneven heating of the outer ring, and the temperature inside the outer ring is different from the outside temperature. When the required temperature error is exceeded, the bearing will fail to meet the specification requirements and become a defective product
