High-universality reduction gearbox special for draught fan

Abstract

The invention discloses a high-universality reduction gearbox special for a draught fan. The high-universality reduction gearbox special for the draught fan comprises a main body, a driving wheel, a speed reduction wheel, an oil storage cavity, a filtering device, a driving wheel and a lubricating device. The filtering device comprises a partition plate, flow guide holes, a filtering block, filtering holes, filtering springs, a static plate, louver boards, convection holes and a cleaning mechanism. According to the high-universality reduction gearbox special for the draught fan, lubricating oil is sprayed to the driving wheel and the speed reduction wheel in a spraying mode through the lubricating device to achieve lubricating and cooling, and the using effect of the lubricating oil is improved; and impurities in the lubricating oil are cleaned away through the cleaning mechanism when the reduction gearbox operates, on one hand, the application effect of the lubricating oil is improved, on the other hand, the rotating stability of the driving wheel and the speed reduction wheel can be improved, the universality of the reduction gearbox is further improved, and the application effect of the reduction gearbox is more stable.

Description

technical field [0001] The invention belongs to the field of reduction boxes, in particular to a special reduction box for fans with high versatility. Background technique [0002] The reduction box is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed operating power is decelerated through the gear with a small number of teeth on the input shaft of the reduction box and the large gear on the output shaft to achieve the purpose of deceleration; Different application scenarios have different operation effects on the structure of the gears inside the reduction box. Generally, when lubricating the inside of the fan-specific reduction box, pour the lubricating oil into the lubrication box, and carry out all the gears through the drive of the gears. Lubrication; however, this method reduces the use efficiency of the lubricating oil, and at the same time, due to the special application environment, it will...

[0002] The reduction box is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed operating power is decelerated through the gear with a small number of teeth on the input shaft of the reduction box and the large gear on the output shaft to achieve the purpose of deceleration; Different application scenarios have different operation effects on the structure of the gears inside the reduction box. Generally, when lubricating the inside of the fan-specific reduction box, pour the lubricating oil into the lubrication box, and carry out all the gears through the drive of the gears. Lubrication; however, this method reduces the use efficiency of the lubricating oil, and at the same time, due to the special application environment, it will be mixed with impurities; through this method of lubrication, the impurities washed down by the lubricating oil will be driven to the gear by the rotation of the gear again , which will increase the gear wear; at the same time, the gear speed will change when the gearbox is running, but the existing lubrication technology cannot change the lubrication effect with the change of the gear speed
