Description

Technical Field

[0001] The utility model relates to the technical field of coaxiality adjustment, and more specifically to the technical field of a coaxiality adjustment device for a hydraulic oil pump coupling. Background Art

[0002] When installing the hydraulic pump, the coupling needs to be aligned and centered; the quality of the coupling coaxiality is directly related to the vibration, noise and service life of the hydraulic pump during operation. When adjusting the coaxiality of the hydraulic oil pump coupling, keep the oil pump base stationary, set up a dial indicator at the coupling, and adjust the motor base according to the specific value of the dial indicator to achieve alignment and centering of the coupling. At present, the following two solutions are generally used to adjust the coaxiality of the hydraulic oil pump coupling:

[0003] Solution 1: Use a crowbar and a welded bolt bracket to adjust the coaxiality. The installer uses a crowbar to pry up the oil pump motor, adds a gasket to the bottom of the oil pump motor to adjust the position of the motor longitudinally; and uses an adjusting bolt to push the motor base to adjust the position of the motor horizontally.

[0004] Solution 2: Use a crowbar and a hammer to adjust the coaxiality. The installer uses a crowbar to pry up the oil pump motor, adds a gasket to the bottom of the oil pump motor to adjust the position of the motor longitudinally; and uses a hammer to hit the base on one side of the motor to adjust the position of the motor laterally.

[0005] The two solutions have the following problems when adjusting:

[0006] When using a crowbar to adjust the two solutions, it is difficult to control the force, which may cause the motor base to shift significantly. Secondly, when adjusting a hydraulic pump that is slightly larger in size and weight, multiple installers are required to work together to make the adjustment.

[0007] Both schemes require high technical level of the installers. In addition, when adjusting the lateral position of the motor, the installers need to control the motor adjustment distance by feeling. There is no specific monitoring instrument for distance monitoring, and the moving position of the motor base cannot be accurately controlled. It needs to be adjusted back and forth repeatedly. After the adjustment is completed, the coaxiality deviation of the coupling is large.

[0008] When the first solution uses the adjusting bolt to push the motor base horizontally, it is necessary to install or weld the adjusting bolt bracket near the motor base. The construction is complicated and has high requirements on the installation base of the entire oil pressure pump.

[0009] When using a hammer to hit the base of the horizontally movable motor, it is difficult to control the hitting force, and the base of the horizontally movable motor cannot be accurately and smoothly moved. At the same time, for a large and heavy motor, using a hammer to hit the base of the movable motor has little effect. Utility Model Content
