Description

Technical Field

[0001] This utility model belongs to the field of dynamometer installation equipment, specifically relating to an adjustment device for adjusting the coaxiality of a large motor. Background Technology

[0002] When a dynamometer is in use, the motor needs to drive the back-end equipment to rotate at high speed. In order to reduce the vibration generated during rotation, the coaxiality error between the main shaft of the dynamometer and the main shaft of the back-end equipment needs to be minimized as much as possible, thereby protecting the normal use of the dynamometer and improving the service life of the equipment.

[0003] When installing a dynamometer, the motor is quite heavy. Operators adjust the motor's position by using pry bars and copper rods to move it. This method is time-consuming and labor-intensive, with low efficiency and difficulty in ensuring adjustment accuracy, wasting both time and manpower. There is an urgent need for a method that can solve this problem. Utility Model Content

[0004] In view of the problems existing in the background art, the present invention provides an adjustment device for adjusting the coaxiality of a large motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustment device for adjusting the coaxiality of a large motor, comprising a motor, a fixing block, a jack, and a dial indicator. The motor is placed on the upper surface of a workbench, and the outer side wall of the motor's main shaft is in contact with the measuring head of the dial indicator. The fixing block is installed on the upper surface of the workbench by fixing bolts, and the fixing block is located on the outer side of the four corners of the motor. The jack is located between the motor and the fixing block, and the base of the jack is connected to the fixing block by screws, with the top of the jack in contact with the base of the motor.

[0006] The fixing block is a cuboid with multiple fixing holes on its upper surface. These fixing holes are adapted to the mounting grooves of the workbench, and fixing bolts are inserted into the fixing holes. The rear end face of the fixing block has threaded holes that are adapted to the mounting holes of the jack base.

[0007] The lower end of the fixing bolt is engaged in the mounting groove, the upper end of the fixing bolt protrudes from the fixing block, and a nut is provided at the protruding end of the fixing bolt.

[0008] The beneficial effects of this utility model are as follows: This utility model provides an adjustment device for adjusting the coaxiality of a large motor. The adjustment device has a simple structure, is easy to install, and is convenient to use. The device uses a jack to drive the motor to move, which can effectively reduce the construction difficulty for operators. The required movement distance can be calculated by using the stroke parameters of the jack, thereby effectively improving labor efficiency and reducing adjustment difficulty.
