Slewing mechanism of maintenance method

2019 - slewing mechanism of maintenance method 01 - 11 rotary motor maintenance of hydraulic oil and gear oil rotary motor and hydraulic oil to maintain the whole hydraulic system maintenance at the same time, about 2000 hours to replace the hydraulic oil at a time. Slewing reducer gear oil maintenance need to replace about 1000 hours. （ Note: the replacement cycle as a theoretical reference, your boss will do adjustment according to actual working condition and so on. ） In the daily operation, we are going to observe from the oil dipstick slewing reducer gear oil level, some cases will be found abnormal loss of lubricating oil, we should open the big gear ring ( Arm at the bottom of the cylinder, butter filling mouth) , check whether the lubricating oil is through the rotary gear reducer seal leakage into the big gear ring cavity. Slewing bearing maintenance in slewing bearing on the maintenance of common pitfalls, a lot of people think slewing bearing butter time interval with the forearm are the same, need to play every day. It seems to do actually played a bad role, because the lubrication cycle is too short, can make butter in bearing too much, thus broken shield leak out. A leak means that there will be internal impurities into the bearing, resulting in abnormal bearing wear lead to abnormal operation. According to the maintenance standard, slewing bearing lubrication interval is 250 hours, at the same time in the beat butter to rotate the excavator, filling every 15 degrees butter at a time. （ Note: in different working condition, the lubrication cycle can be adjusted according to rotation operation appropriate strength. Charging a butter in about a week. ） Rotary big wheel ( Rotary bearing) Maintenance of rotary big wheel part includes slewing ring gear, reducer etc. We usually open the big arm cylinder at the bottom of the observation hole, can be observed that the big gear ring cavity ring gear wear and lubrication conditions. With the use of the machine, the slewing ring gear shield will be aging problems, such as in rainy days, rain will follow the slewing ring gear leak into the big gear ring cavity, rotary water. Butter due to the dilution of water in the cavity, and lubrication effect was not up to standard, will aggravate the ring gear wear and tear, the foreign minister soaking time of flake will rust on the ring gear, eventually led to the slewing ring, serious is the ring gear. So, each machine friends avoid rainy day, while parked also will be parked in the site of the shelter. If you find a big gear ring cavity with water, we can adopt the way of excavator uphill or downhill, make water flow outside the cavity.
