Problems solved by technology

[0003] This kind of motor is a self-radiating type. When the motor is working, the wind is sucked from the rear cover to achieve cooling effect. In order to facilitate heat dissipation, the rear cover of the motor is designed in a honeycomb shape. The viscosity of the grease increases, and it is easy to glue, resulting in greater running resistance and greater power loss; the fluidity of the grease becomes poor, and solid impurities may cause extrusion to the gears that are in contact with each other, affecting their service life; Greasing and refatting are also more difficult

Abstract

The invention discloses a low-speed driving device of an electric block double-speed motor, and relates to the technical field of electric blocks. The low-speed driving device of the electric block double-speed motor is connected between a main lifting motor and a secondary lifting motor, and comprises a wheel set for linking the main lifting motor with the secondary lifting motor; a closed outershell is arranged outside the wheel set; and lubricating oil is applied to the wheel set. Through the closed structure, the possibility of dust entering the outer shell is reduced, and high bearing capacity is achieved; and the lubricating oil has the following advantages: each gear in a gearbox is excellently lubricated; all the gears can be contacted with gear oil during working to prevent gearsurface wear, friction, gluing and sintering; the transfer efficiency is improved; the power loss is reduced; the enough protecting effect on the gears is achieved; and the service life is prolonged.Because of the lubricating effect, the noise and the vibration are reduced; and after the lubricating oil is fed, the fluidity is higher compared with lubricating grease, so that the lubricating oil can flow into smaller gaps more quickly, and the working efficiency of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of an electric hoist, in particular to a slow-speed drive device for a double-speed motor of an electric hoist. Background technique [0002] The slow drive device is an independent reduction system used on the motor of the hoisting machine. In the hoisting industry, the two-speed motor that electric hoists currently use most in China is called a master motor, which is composed of a main hoisting motor, a slow drive device, and an auxiliary hoisting motor. The lifting motor is integrated, so the lubrication of the gears can only be lubricated with grease. [0003] This kind of motor is a self-radiating type. When the motor is working, the wind is sucked from the rear cover to achieve cooling effect. In order to facilitate heat dissipation, the rear cover of the motor is designed in a honeycomb shape. The viscosity of the grease increases, and it is easy to glue, resulting in greater running resistance and ...
