Adjustment tool for large-motor rotor and stator

Abstract

The invention relates to a large motor and particularly relates to an adjustment tool for the large motor. The adjustment tool for a large-motor rotor and stator includes a main ruler and an auxiliary rule. The main rule is hollow inside and the upper edge of the outer surface of the main ruler is provided with a scale and the side face of the main ruler is provided with an opening groove. Two walls at the inner side of the main ruler are both provided with oblique planes which oblique from inside to outside and from top to bottom. The auxiliary ruler is inserted into the main ruler and the side of the head end of the auxiliary ruler is provided with oblique planes corresponding to the oblique planes in the main ruler. A slide shaft is arranged at the starting point positions of the oblique planes of the auxiliary ruler. The tail end of the auxiliary ruler is provided with a slide block which is inserted into the opening groove in the surface of the main ruler. The adjustment tool is capable of reducing effectively construction personnel, improving device installation efficiency and improving effectively installation precision.

Description

technical field [0001] The invention relates to a large motor, in particular to an adjustment tool for a large motor. Background technique [0002] During the installation of large motors, the adjustment of the air gap and the magnetic centerline is the key to the adjustment of the rotor and stator of the motor. [0003] In the past, under normal circumstances, there were 2 ways to deal with this. 1. Use a feeler gauge to measure the air gap. 2. Use an italic or conical probe to measure with a micrometer or vernier caliper. In method 1, since the air gap of a large motor is generally 8-16 mm, the thickness of the feeler gauge cannot be achieved generally, and several feeler gauges need to be combined to measure. There are 48 measuring points for a 24-pole motor. It takes a long time to use the feeler gauge method, and the work efficiency is low. In method 2, since the probe cannot be read directly, it is necessary to smear a layer of red lead powder on the probe,...

Problems solved by technology

In method 1, since the air gap of a large motor is generally 8-16 mm, the thickness of the feeler gauge cannot be achieved generally, and several feeler gauges need to be combined to measure. The measurement points of a 24-pole motor are 48 points. It takes a long time to use the feeler gauge method and the work efficiency is low.

In method 2, since the probe cannot be read directly, it is necessary to smear a layer of red lead powder on the probe, and then use a micrometer or a vernier caliper to measure according to the imprint. After two measurements, this method has a large error

Can not improve the installation accuracy of the equipment
