Excavations machine rotary big wheel repair share with care skills

Big wheel of the rotary big wheel local care including rotary ring gear, deceleration machine, the center section. We usually base on the side of the cover board opened the big arm, could see the big gear ring cavity is smooth, and the status of the ring gear wear and tear. With the use of the machine, rotary center section of the shield will present aging, if rainy day, rain will follow the rotary center section leak place into the big gear ring cavity, provoked rotary water. This will greatly affect the love machine of the use of the slewing ring gear life. Excavations machine in the process of excavating machine work, butter in the cavity due to was diluted by water, smooth effect can not meet the specification, will aggravate the ring gear wear and tear, the foreign minister soaking time can make the ring gear feng spalling, finally incur slewing ring. The most serious is the ring gear failure. Liugong excavating machine inspection and maintenance: the slewing gear check and smooth oil change cycle or one year for every 2000 hours, 20 tons machine butter filling amount to about 36 litres per person ( Two barrels) 。 Base on a regular basis to open big arm, the front frame, four square lid to check the gear ring and smooth condition. Remaining or found at the bottom of the water to drivers X aerial opened the cover plate release water in the cavity. Slewing bearing and maintenance care goes on slewing bearing users widespread misunderstanding, thought that smooth oil of slewing bearing with large forearm smooth the same cycle, play every day. Instead of practice, such as the opposite effect. If smooth cycle is too short, too much can make smooth in the bearing oil, which appeared to be broken shield. Have leaked at the same time also can have impurities into the bearing internal, has always been the normal operation of bearing damage. Caterpillar introduce smooth distance of slewing bearing is every 250 hours. Butter, at the same time with up and down in the taxi to rotating machines at the same time, every 15 ° to play a full gun smooth oil is enough. In different applications can be based on your work strength properly adjust smooth cycle, can be a normal 1 week or so smooth.
