一、轧钢机万向接轴的结构 2800中板机组的两架轧机,电动机功率均为4800千瓦。为适应轧辊开口度的调整,采用了万向接轴与电动机(或人字齿轮座)相连。其示意图见图1。接合部位通常称为虎口,通过两块半圆形铜滑板,用铜的方滑块卡在扁头的开口部位来传递力矩。由于轧制力矩很大,冲击和磨损都很强烈,生产过程中,必须有良好的润滑。二、铜半圆滑板存在的问题万向接轴虎口部位的润滑,苏联原设计系用干油自动润滑(见图1)。自动干油站定时定量将干油送入万向接轴托瓦,通过轴颈上开的进油孔,进入万向接轴的中心油槽,再分别导入两端虎口处,实现对铜滑板的润滑。原设计的意图是:尽管万向接轴在不停地运转,但进油孔始终处于托瓦内,干油可依靠压
First, the rolling mill universal joint structure 2800 plate mill two mills, the motor power is 4800 kilowatts. In order to meet the roll opening adjustment, using a universal joint with the motor (or herringbone gear) connected. The schematic diagram shown in Figure 1. Joints are often referred to as the tiger’s mouth, through two semicircular copper skateboards, copper square slider stuck in the opening of the flat head to transmit torque. Due to the large rolling torque, impact and wear are very strong, the production process, there must be good lubrication. Second, the problem of semicircle skateboard universal joints Hukou mouth lubrication, the original design of the Soviet Union with dry oil automatic lubrication (see Figure 1). Automatic dry gas station quantitatively and quantitatively sends the dry oil into the universal joint support tile, enters the center oil groove of the universal joint shaft through the oil inlet hole opened on the journal, and then introduces the central oil groove at both ends respectively, lubricating. The original design intent is: Despite the universal joints in the non-stop operation, but into the hole is always in Tuowei, dry oil can rely on pressure
