AI Technical Summary

Technical Problem

The existing low-speed direct drive resistive motors are susceptible to impact loads caused by vibration and shaking during handling or operation, and the shaft sealing device of the rolling bearing is difficult to completely prevent dust from entering, reducing the protection performance of the motor.

Method used

A high-protection low-speed direct-drive reluctance motor is designed, using a pulling buckle assembly and a sealing gasket structure. By pulling the pulling ears of the pulling buckle assembly, the sealing gasket contacts the spindle, clamps the spindle, and avoids impact loads; at the same time, the sealing gasket contacts the shaft sealing ring to prevent dust from entering.

Benefits of technology

It effectively avoids the impact loads of the spindle and rolling bearings during the motor handling process, and improves the impact protection of the motor; at the same time, it prevents dust from entering the inside of the motor, and improves the dust protection of the motor.

Abstract

The invention provides a high-protection low-speed direct-drive reluctance motor, and relates to the technical field of reluctance motors, the high-protection low-speed direct-drive reluctance motor comprises a machine base, a bottom plate, a machine shell and a top plate are sequentially arranged above the machine base from bottom to top, two groups of pull buckle assemblies are arranged on the top plate, and a pull sliding rod is slidably arranged at the center of a boss seat of each pull buckle assembly; a transverse sliding plate used for driving the first pressing ring to translate is rotatably arranged on the rotating seat at the lower end of the pull sliding rod, one end of the transverse sliding plate is slidably arranged on the sliding table, two swing rods are arranged on each of the two sides of the first pressing ring, the lower ends of the swing rods are hinged to the first pressing ring, and lifting rotating seats are hinged to the upper ends of the swing rods. A first sealing gasket is arranged on the inner side face and the upper surface of a circular ring of the first pressing ring. In the lifting process of the pull sliding rod, the lifting plate drives the first pressing ring to horizontally move, the inner circular ring faces of the two first sealing gaskets make contact with the main shaft, the main shaft is clamped, and therefore the situation that the main shaft and a rolling bearing are damaged due to impact loads in the motor carrying process can be avoided, and the impact resistance protection performance of the motor is improved.
