Structure of transmission gear box

Abstract

The invention discloses a structure of a transmission gear box. The structure of the transmission gear box is suitable for various industries, such as metallurgy, petroleum, chemical industry, sugar refining, mines and transportation. The structure of the transmission gear box mainly comprises a gear box body, a box cover, a bevel gear transmission mechanism and a first planetary gear transmission mechanism, wherein a first sun wheel shaft of the first planetary gear transmission mechanism is delicately designed to be in a flexible long shaft structure, a first planet carrier and a hollow gear shaft are movably sleeved outside the first sun wheel shaft, and input power passes through the first planetary gear transmission mechanism and the hollow gear shaft and is transmitted to an output stage gear through the bevel gear transmission mechanism, and then is output through an output shaft from multiple angles. The modified structure of the transmission gear box is more compact, and has the advantages of being small in size, light in weight, large in total speed ratio, strong in output torque, large in bearing capacity, stable in transmission, high in transmission efficiency, and the like, can adjust the structure of the power transmission according to different occasions, meets the requirements for special installation of whole equipment, lowers purchase cost of the equipment, widens industrial application scope, and enhances economic advantages.

Description

technical field [0001] The invention relates to a gear box structure of mechanical equipment, in particular to a transmission gear box structure with a new transmission form and structure. Background technique [0002] The transmission gearbox is an important part of mechanical equipment. It undertakes the power transmission of mechanical equipment, such as the common tension leveler in mechanical equipment. As an important equipment in continuous casting equipment in the iron and steel industry, due to its special structure and limited space On the one hand, the transmission gearbox for the tension leveling machine needs to meet the requirements of low-speed and high-torque output, and on the other hand, it is also greatly limited in terms of external and installation dimensions. The disclosed Chinese patent No. 200920119442.2 of the "vertical roller mill gearbox" and the disclosed Chinese patent No. 201020196411.X of the "mixer power transmission gearbox" all relate to a b...

AI Technical Summary

Problems solved by technology

However, the power transmission design between their bevel gear transmission mechanism and planetary gear transmission mechanism is not smart and compact enough to effectively meet the requirements of the gearbox for low-speed, high-torque output, and high-speed ratio transmission, especially the gearbox is large in size and heavy. Heavy, its power transmission cannot be adjusted according to the actual work needs, which greatly affects the speed ratio and torque output by the gearbox
