Problems solved by technology

The edge transmission has the characteristics of compact layout and low price, but the transmission efficiency is low, the maintenance workload is large, and the operation failure rate is high
The central transmission has the advantages of high transmission efficiency, safety and reliability, and is favored by users. However, the reducer is large in size and expensive. At present, the central transmission reducer with a transmission power of more than 4500kW does not have the processing and manufacturing capabilities and needs to be imported from abroad.

Abstract

The invention discloses a transmission gear of a tube mill. An input shaft (15) is arranged on a torsion frame (13); an input mating gear (17) is engaged with an input gear (14) on the input shaft (15); a flexible hollow shaft (16) is arranged at the centre of a join box body (3); the input mating gear (17) and a secondary sun wheel (5) are arranged on the flexible hollow shaft (16); a secondary planetary wheel (6) on a secondary planetary wheel shaft (7) is engaged with the secondary sun wheel (5); a secondary inner gear ring (4) is arranged on the join box body (3); the secondary planetary wheel shaft (7) is connected with a tertiary sun wheel (8); a tertiary planetary wheel shaft (9) is arranged on a tertiary planetary frame (10) on the torsion frame (13); a tertiary planetary wheel (11) on the tertiary planetary wheel shaft (9) is engaged with the tertiary sun wheel (8); and a tertiary inner gear ring (12) is connected on the join box body (3). The transmission gear is of fully enclosed structure and is connected by flanges, the installation is easy, and the installation period is short.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device of a tube mill. Background technique [0002] As we all know, in the dry process cement production line, the transmission device of the tube mill mainly includes center transmission and edge transmission. The edge transmission has the characteristics of compact layout and low price, but the transmission efficiency is low, the maintenance workload is large, and the operation failure rate is high. The central transmission has the advantages of high transmission efficiency, safety and reliability, and is favored by users. However, the reducer is large in size and expensive. At present, the central transmission reducer with a transmission power of more than 4500kW does not have the processing and manufacturing capabilities and needs to be imported from abroad. In the past two decades, with the continuous progress of cement production technology, the level of cement indu...
