Motor bearing assembling clearance detecting method and device

Abstract

The invention discloses a motor bearing assembling clearance detecting method. The method comprises steps as follows: S101, a feeler gauge is inserted in radial clearance between a bearing block and an isolating sleeve, the feeler gauge is taken out and a bearing outer cover is put on a bearing after the radial clearance is equally spaced in the circumferential direction through adjustment and meets the size requirements of the feeler gauge; S102, a plurality of clearance detecting pieces are inserted into the radial clearance through process detection holes in the bearing outer cover, fastening bolts symmetrically arranged on the bearing outer cover are screwed tightly, and the clearance detecting pieces are pulled; S103, whether the radial clearance meets the size requirement of the clearance detecting pieces is judged, if yes, the step S104 is performed, and otherwise, the step S105 is performed; S104, the clearance detecting pieces are taken out, the feeler gauge is inserted into the radial clearance, and the step S106 is performed; S105, the bearing outer cover is taken down, and the step S101 is performed again; S106, whether the radial clearance is uniformly spaced in the circumferential direction is judged, if yes, operation ends, and otherwise, the step S107 is performed; S107, the bearing outer cover is taken down, and the step S101 is performed again. The invention further discloses a motor bearing assembling clearance detecting device. The stability of clearance adjustment of the bearing is improved.

Description

technical field [0001] The invention relates to the technical field of motor design, in particular to a method for detecting assembly gaps of motor bearings. In addition, the present invention also relates to a motor bearing assembly gap detection device, which is used to realize the above method. Background technique [0002] With the development of modern technology, the performance requirements for motors are also increasing, and correspondingly, the production requirements for motors are also increasing. Bearing assembly is an important process in the motor assembly process, and the assembly accuracy of each bearing assembly component affects the assembly quality of the motor. In order to meet the precision requirements of the motor operation, during the assembly process of the motor parts, it is necessary to particularly improve the requirements for the assembly accuracy of the motor bearings, especially the centering of the motor bearing parts. [0003] For motors wi...

Problems solved by technology

However, in the existing assembly process, the detection method of the above-mentioned clearance is used to align the bearings with guide rods. However, this method is not accurate for the clearance detection of two different types of bearings at one end.

In addition, the bearing clearance will still be affected when the bearing outer cover is installed, and the existing technology cannot effectively avoid this effect
