2DPJ—30型耙矿绞车(以下简称电耙)是我矿选矿车间的主要运输设备。选矿车间是三班作业,电耙平均每天工作约16小时。电耙在工作中经常制动,使制动器的温度高达120～150℃。传动机构也在高温下工作,致使橡胶密封圈容易老化、失效、齿轮传动润滑不良,齿面耐磨强度低,设备漏油,噪声很大。这样使电耙的使用寿命与原设计相差很远。据统计重庆矿山机器厂制造的2DPJ—30型耙矿绞车原设计工作1350～1600小时检修一次,更换行星齿轮、太阳齿轮,滚动轴承密封等,而在我矿选矿车间使用中,实际开动为39天,共
2DPJ-30 rake mine winch (hereinafter referred to as electric rake) is my ore dressing plant’s main transport equipment. Dressing shop is three shifts, the average daily work of harrows about 16 hours. Electric rake often brake at work, so that the brake temperature up to 120 ~ 150 ℃. Transmission also work under high temperature, resulting in easy aging of rubber seals, failure, bad gear transmission, wear resistance of the tooth surface is low, equipment leakage, noise is great. This will make the life of the electric rake a long way from the original design. According to statistics, the mining machine factory in Chongqing Mining 2DPJ-30 rake mine winch original design work 1350 ~ 1600 hours a maintenance, replacement of planetary gears, sun gear, rolling bearing seals, etc., and in my mine dressing shop, the actual start for 39 days , Total
