Five-point positioning-based shaft-sticking type motor installation test device

Abstract

The invention discloses a five-point positioning-based shaft-sticking type motor installation test device, which comprises a bottom plate and two movable brackets. The brackets are provided with transverse brackets capable of moving up and down; two transverse positioning rollers capable of moving left and right are arranged on the transverse brackets; a middle rotating shaft of each transverse positioning roller is connected with a second motor through a second screw rod; and movable supports capable of being rotationally opened are arranged at the upper ends of the brackets, longitudinal positioning rollers are arranged in the middles of the movable supports, and middle rotating shafts of the longitudinal positioning rollers are connected with a fourth motor through a fourth lead screw. A motor installation frame is arranged between the two brackets, an arc-shaped adjusting groove is formed in the motor installation frame, and an adjustable supporting shaft is arranged on the arc-shaped adjusting groove. The three rollers and the two adjustable supporting shafts are integrated, so that five-point positioning of mounting and debugging of the spindle sticking type motor spindle is achieved, and compared with a traditional mounting mode of a three-jaw chuck, the adjusting speed is higher, and the adjusting is more accurate.

Description

technical field [0001] The invention relates to a shaft-holding motor installation test device based on five-point positioning. Background technique [0002] Due to the large size and no bearing support of the existing shaft-holding motors, the length of the propulsion shaft of the ship is relatively long and the weight is heavy. Therefore, when testing the performance of the shaft-holding motors, it needs to be completed in the factory, and a special universal test device is required for installation. debugging. [0003] In the low-speed performance test of the shaft-holding motor, because there is no precise positioning of the bearing assembly and the shaft, it is necessary to adjust the assembly accuracy of the main rotor of the motor and the stator of the motor frame to meet the requirements of a uniform air gap between the stator and rotor. The existing adjustment The method is often to use a dummy shaft and install bearings at both ends of the dummy shaft for adjustme...

Problems solved by technology

[0003] In the low-speed performance test of the shaft-holding motor, because there is no precise positioning of the bearing assembly and the shaft, it is necessary to adjust the assembly accuracy of the main rotor of the motor and the stator of the motor frame to meet the requirements of a uniform air gap between the stator and rotor. The existing adjustment The method is often to use a dummy shaft and install bearings at both ends of the dummy shaft for adjustment. The adjustment is subject to the specific structural parameters of the dummy shaft and bearings, and even there are no available models for bearings. The versatility is not strong and the cost is low. very high
