Central multi-drive transmission with extended output shaft of reducer

Abstract

The invention discloses a central multi-drive transmission device with a lengthened output shaft of a reducer, which solves the problems of intermediate transition transmission, low efficiency and high cost in the existing device, and is characterized in that the casing of the reducer is lengthened and an extended output shaft is provided , the end of the extended output shaft is equipped with a pinion, and the pinion directly meshes with the large gear; the reducer is equipped with an oil discharge pipeline, including an oil discharge pipe in the box, a combined hole cover, a through-plate pipe joint, an oil discharge pipe outside the box, a stop valve, and an oil plug, etc. . In the present invention, the small gear at the shaft end of the extended output shaft of the reducer is used to directly drive the large gear, and the transmission efficiency is high; the set oil discharge pipeline does not need to dismantle the reducer when changing oil, and the replacement is convenient; the combined hole cover, the through-plate pipe joint, etc. are composed The pipeline can be disassembled so that the oil discharge pipeline does not affect the replacement of the reducer.

Description

technical field [0001] The present invention relates to a transmission device, more specifically to a multi-point drive transmission device for a central drive thickener. Background technique [0002] The central multi-point drive system is to distribute three or more reducers evenly on the meshing circle of the large gear, each of which rotates independently, and the pinion at the output shaft end of the reducer drives the large gear together using the principle of self-synchronization. The number of multi-point drive transmission mechanisms is large and the torque is large; due to the needs of structure and strength, the size of the transmission hub is large, the distance between the plane on the cover plate of the central transmission box and the tooth surface of the central rotary large gear is relatively large, and the output shaft of the ordinary reducer is small. The gears cannot mesh with the large gears. In order to realize the normal meshing of the large and small ...

AI Technical Summary

Problems solved by technology

The number of multi-point drive transmission mechanisms is large and the torque is large; due to the needs of structure and strength, the size of the transmission hub is large, the distance between the plane on the cover plate of the central transmission box and the tooth surface of the central rotary large gear is relatively large, and the output shaft of the ordinary reducer is small. The gears cannot mesh with the large gears. In order to realize the normal meshing of the large and small gears, people use intermediate transition transmission, which has low transmission efficiency, high cost and long production cycle.

Moreover, when changing the oil of the reducer, it is necessary to remove the reducer and replace the lubricating oil of the reducer, which is time-consuming and inconvenient
