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 between the upper and lower ring gap is clearly 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 edge of collapse.
3. Rotary bearing sealing system and lubrication system is the protection of rotary bearings and maintenance system, Slewing Bearing 85% of the users did not do this, all the reasons is that the operator, especially the driver of their own, resulting in rotary bearing dry consumption. The following picture, Slewing Bearing 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, Slewing Bearing 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,Slewing Bearing and even the user directly forced to pull the rotary bearing rotation, the results of the tragedy occurred.
1. In the rotation of the bearing when the sound is unknown, Slewing Bearing not quickly filling the grease, but the addition of kerosene, directly from the bearing gap, Slewing Bearing the seal pulled out, directly around the filling, and positive and negative rotation, cleaning, as far as possible The cleaning. At this time the internal groove of the slewing bearing, the ball, the ball will get a slight clean. Wash off the rotating bearing debris, more than anything else.
2. After cleaning the bearings, filling the oil, Slewing Bearing 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, to prevent dust, Slewing Bearing dust, debris into the bearing channel, to ensure that within 2-3 can be reluctant to use.
General small and medium-sized motor running a little longer, Slewing Bearing bearing and end bearing between the bearing room often change, can make the bearing jacket with the motor running and rotation, which is often encountered by motor users "bearing running" problem The The greater the roughness of the inner diameter of the end bearing, the greater the roughness of the knife blade, after several disassembly, Slewing Bearing bearing operation heat expansion, squeeze bearing treasure, bearing running often by radial or vibration after the processing of the knife marks The peak will continue to become smaller, the bearing chamber diameter gradually increased bearing bearing and end cap bearing room with the gap increases. Bearing room diameter tolerance of the old product is generally equivalent to J7, Slewing Bearing the new series such as Y2 motor for the H6, is to consider the bearing operation will heat expansion, etc., end cap bearing tolerance of the upper limit is positive, the next difference is zero. Slewing Bearing In case of the end cap bearing chamber size is poor, the bearing is inferior, coupled with the bearing surface roughness of the larger, the bearing by the radial tension and other adverse conditions, bearing room and bearing with the gap is easy to appear Ambassador coat jacket in the operation of the jacket rotation occurred in the phenomenon, affecting the normal use of the motor.
The bearing chamber is playing with mahjong or knurled. Slewing Bearing Bearing room to play mahjong is to remove the end of the shed cover, with the tip of the steel punch to the end of the bearing chamber and the bearing with the circumferential surface of the cloth evenly puddle pit, Slewing Bearing each pit around the glitch to make bearing table And the roughness increases, thus reducing the pore size, cleaning dust and other debris can be re-installed. After such treatment, the operation of a period of time or re-disassembly several times, the peak of small pits or knurled bumps soon become less wear, bearing room roughness decreases, Slewing Bearing the aperture quickly restored to its original size, the bearing jacket may turn again The This repair method can only be used for short-term emergency repair processing.
Mattress gasket treatment. The center of the high H160 and below the general small motor, Slewing Bearing the bearing structure is relatively simple, even without the bearing inner cover or cover, bearing and end cap axial pad with wave spring washer to adjust the axial clearance to reduce bearing noise and vibration
