Reduction gearbox of sand dredger and machining method for reduction gearbox

Abstract

The invention discloses a reduction gearbox of a sand dredger and a machining method for the reduction gearbox. The reduction gearbox of the sand dredger comprises an outer shell, a transmission box, a transmission shaft, a shaft end position, a base, a fixing hole, a brake transmission shaft hole, a connecting pillar, a sealing block, an end cover, a tooth groove, a first shaft groove, a second shaft groove, an oil dripping hole and a motor. The reduction gearbox of the sand dredger has the beneficial effects that a reverse self-locking function is achieved, a large speed reduction ratio can be achieved through the motor, an input shaft and an output shaft are not on the same axis or the same plane, the provided speed reduction power is large, and speed reduction control can be easily carried out over the sand dredger. The reduction gearbox is small in size, high in transmission efficiency and high in accuracy. The connecting pillar can be dismounted and mounted, the brake transmission shaft hole enables the brake force transmitted by a brake to act on the sand dredger, and the speed of the sand dredger is rapidly reduced. The fixing hole enables a sand dredger body to be fixedly connected with the reduction gearbox, the service life is long, work efficiency is high, and operation is simple. The oil dripping hole enables lubricants to enter the reduction gearbox, the use time is prolonged, and the reduction gearbox of the sand dredger is suitable for application and popularization.

Description

technical field [0001] The invention relates to a gear box, in particular to a sand mining ship gear box and a processing method thereof, belonging to the field of mechanical equipment. Background technique [0002] With the development of society, more and more machines are valued and utilized by people, and the reduction box inside the sand dredging ship often determines the speed and control of the sand dredging ship berthing. The gearbox is a combination of a geared motor and a large gearbox. The development history of my country's gearbox industry has been nearly 40 years. In various fields of national economy and national defense industry, gearbox products are widely used. increase the output torque. The nominal transmission ratio of the reducer is the ratio of the speed of the input shaft to the speed of the output shaft. The auxiliary motor and auxiliary reducer depend on the function of use, or the load of the rotary kiln is too large, and it acts as a booster; o...

AI Technical Summary

Problems solved by technology

[0003] At present, there are some deficiencies in the gearbox of sand mining ships in my country, such as large volume, low transmission efficiency and low precision.

Flexible splines have limited life, are not impact resistant, and have poorer rigidity than metal parts
