Slewing Bearing Protection Line
1. Excavation of the rotary bearing of the rig There are intermittent pieces of sound - like crushed crushed stone, harsh metal crushed sound, Slewing Bearing the fault tells you that the slewing bearing has been worn seriously.
2. Excavation of the rotary bearing of the upper and lower collar gap is obviously open, you can simply measure the four points of the rotary bearing, outside the ring gear, Slewing Bearing or the ring gear as a benchmark to determine the gap between the inner and outer ring, if more than 2 mm below, Can still adhere to February, more than 3 mm above the bearing facing the brink of collapse.
3. Rotary bearing sealing system and lubrication system is the protection of rotary bearings and maintenance systems, 85% of the users did not do this, Slewing Bearing all the reasons is that the operator, especially the driver of their own way, resulting in rotary bearing dry consumption. The following picture, the seal has been unable to see, the lubrication is injected after the loss, has been unable to return to heaven.
4. Excavation of drilling machine rotary bearing failure can also be seen in the work of the time, jitter, vibration or forward and backward, Slewing Bearing rotary bearing deformation reached a serious level.
5. digging drilling machine rotary bearing turntable bearings and slewing bearings directly stuck, is more users finally had to stop the final results, and even the user directly forced to pull the rotary bearing rotation, Slewing Bearing the results of the tragedy occurred.
1. In the rotation of the bearing when the sound is unknown, Slewing Bearing not quickly filling grease, but the addition of kerosene, directly from the bearing gap, the seal pulled out, directly around the filling, and positive and negative rotation, cleaning, as far as possible The cleaning. Slewing Bearing At this time the internal groove of the slewing bearing, the ball, the ball will get a slight clean. Wash off the debris of the slewing bearing, more than anything else.
2. After cleaning the bearings, Slewing Bearing filling the oil, the concentration, that is, the viscosity is slightly higher, this time, the seal has been lost, sticky little better, high adhesion rate.
3. Strengthen the temporary protection, Slewing Bearing to prevent dust, dust, debris into the bearing channel, to ensure that within 2-3 can be reluctant to use.
Rotary bearing lubrication is located in the rotary bearing outer ring lubricating grease mouth filling grease to complete, rotary ring gear lubrication is completed by the pre-added grease. Rotary bearings are inside and outside (or up and down) two rubber strips as oil seal, Slewing Bearing outside the oil seal fixed in the lower frame of the rotary bearing inner ring (fixed plate), used to prevent the outside of the debris into the rotary bearings.
