轮胎成型机带束鼓机箱主轴结构的改进

Modification of the Main Shaft Structure of Belt Drum in Tire Building Machine

主要介绍轮胎成型机带束鼓机箱主轴结构的改进。改进前主轴采用整体结构,在轴体内直接加工细长通气孔;改进后带束鼓机箱主轴采用拼接结构,用塑料气管将气体输送到鼓中,大大简化主轴加工工艺,降低主轴加工成本,便于主轴易损件更换,延长主轴使用寿命。改进结构的带束鼓机箱主轴以及成型鼓尾座主轴已用于巨型轮胎成型机生产。

This paper introduces modification of the main shaft structure of belt drum in the tire building machine. In the old design, the main shaft had a single one-piece structure, and the gas channel in the shaft had to be formed by machining. The modification was to use combination structure for the main shaft, so plastic tube could be integrated for gas transportation. After the modification, the processing of the main shaft was greatly simplified, the cost was reduced, the damaged parts could be easily replaced, and the service life of the main shaft was increased. The new design of shaft has already been applied in the belt drum and building drum tailstock in giant-tire building machine.
