Abstract

The invention discloses an anti-reversal device of a vertical motor, and the anti-reversal device comprises a brake disc and a rotating disc, wherein the rotating disc is installed on the spindle of the motor, the brake disc is installed on the end cover of the motor, one side of the brake disc is provided with a plurality of stopping blocks with sliding slopes, the rotating disc is arranged above the brake disc, the underside of the rotating disc is provided with a plurality of fixing blocks corresponding to the stopping blocks, and the plurality of fixing blocks are respectively provided with accommodating holes in which stop pins are arranged and slid up and down along the holes. The anti-reversal device of the vertical motor can reach the anti-reversal effect of the vertical motor, and is simplified in structure and convenient to manufacture, at the same time, the noise is controlled and prevented when the motor is started and stopped, and the stop pin and the motor have the same service life for reliable and steady operation.

Description

technical field [0001] The invention relates to a vertical motor, in particular to an anti-reverse device for a vertical motor. Background technique [0002] At present, in industries such as water pumps, motors are required to have anti-reverse devices to prevent damage to equipment caused by the reverse rotation of the motors, and the motors with anti-reverse devices are mainly vertical motors. The motor anti-reverse device is usually divided into two types: electromagnetic relay structure and pure mechanical structure. Since the structure of the electromagnetic relay needs to be energized separately, and the power supply is usually not the same as or matched with the main power supply of the motor, the general motor manufacturing company adopts a purely mechanical structure. In the past, when making purely mechanical anti-reverse devices for vertical motors, the common method used by motor manufacturers was to use the interaction between spring force and centrifugal forc...
