Recently, Shanghai Electric) total investment of 500 million yuan in the efficient and clean large wind power bearing production line technological transformation project completion and operation of the first units of 3.6 MW offshore wind power bearing off the assembly line,cast bronze marking the Shanghai Electric is a world-class wind power bearing independent R & D and manufacturing capabilities.
Shanghai Electric Group as a strategic lookout power an important part of development, including efforts to build wind power machine and parts (motor, bronze bushing inverter, bearings, hydraulic systems, etc.), a complete wind power industrial chain.
Shanghai Electric to Shanghai United Bearing Co., Ltd. as the basis, the implementation of efficient and clean large wind power bearing production line technological transformation projects with a total investment of 500 million yuan.dry bushing An investment of 2.5 billion, plans to reach annual production in 2012, 1800 (sets) megawatt large wind power bearing capacity,plain bearing annual sales revenue of nearly 5 billion.
How to maintain tractor drive shaft and rear axle.
Shaft maintenance.
1, sleeve bushing should check the drive shaft flange bolts at both ends of the connection and, if loose, tighten the time.
2, the timely filling grease (should be attention to the cross shaft filling and butter, beat butter and guns must be forced to make four needle roller bearings can be lubricated,DU bushing and the drive shaft can not be too much butter filling expansion joints in order to avoid dust cover damaged).
After the bridge maintenance.
1, view whether the rear axle oil leak.
2, after use, bushing should check the temperature rise of the rear axle package, the method is based on the hand can hold down the light after the bridge packet as normal, brass bushing otherwise the temperature is too high, the bridge should check the quantity and quality of oil in a timely manner to add or replace.
3, the process of moving should be noted that the bridge after any abnormal sound, usually when the main gear bevel gear wear off even when the cone bearing preload is too small,Mould guide plate abnormal sound occurs, but to throttle changes more apparent.
4, usually after the bridge should pay attention to the total gap. Is: live two rear mats, handbrake set loose neutral,plasic bushing visual or sensory hand rotating shaft gap size).
