Plane thrust bearing mainly bears axial load in assembly, which is widely used. Although the installation Skf Bearing Loose Ring operation of thrust SKF Bearing is relatively simple, errors often occur in actual maintenance, that is, the installation position of tight ring and loose ring of SKF Bearing is incorrect,
resulting in the loss of SKF Bearing function and the shaft journal is Skf Bearing Loose Ring quickly worn. The inner ring of the tightening ring is in transition fit with the shaft journal. When the shaft rotates, it drives the tightening ring and rubs with the end face of the stationary part. When subjected to the axial force (FX),
the friction torque will be greater than the matching resistance torque of the inner diameter, resulting in the forced rotation of the tightening ring and Skf Bearing Loose Ring the shaft mating surface and aggravating the wear of the shaft journal.
(1) Distinguish the tight ring and loose ring of SKF Bearing (according to the Skf Bearing Loose Ring inner diameter of SKF Bearing, the hole diameter difference is o.1 ~ o.5mm).
(2) Distinguish the stationary Skf Bearing Loose Ring parts of the mechanism (i.e. parts that do not move, mainly assembly parts).
(3) In any case, the loose ring of SKF Bearing should always rest Skf Bearing Loose Ring against the end face of the stationary part.
it can not only greatly save labor, but also is especially suitable for occasions where the position is Skf Bearing Loose Ring limited and large hook wrench cannot be used. The specific operations are as follows: place the hardened gasket s at the end of the disassembly sleeve, gently tighten the nut m,
and then evenly tighten the hardened bolts K evenly distributed along the circumference until the required Skf Bearing Loose Ring clearance reduction is obtained. Since the disassembly sleeve is self-locking by the friction of its conical surface, it will not loosen even if the compression device is removed. In this way, the compression nut M can be safely removed and replaced with a fixed nut to compress the disassembly sleeve.
During installation, a very thin layer of lubricating oil must be coated on the mating surface of the return sleeve to reduce friction and facilitate installation. However, be careful not to apply thick oil,
otherwise the disassembly sleeve will lose its self-locking ability. When the compression screw and nut are removed to replace the fixed nut, the disassembly sleeve will loosen and deviate from the set position, resulting in installation error. In addition, in the working process, the lubricant will gradually be squeezed out or escape from the fitting gap, resulting in the loosening of the original interference fit of SKF Bearing.
When the installed SKF Bearing is removed and then installed on the journal, the nut cannot be screwed to the original position as it is, because the original fit of the SKF Bearing System has become loose after a long time of work,
which is due to the gradual loosening of the thread, the permanent deformation of the fitting surface due to pressure, and certain wear due to friction. In this case, the radial clearance reduction, axial thrust or expansion must be re measured during installation.
For all standard disassembly sleeves and threaded shaft ends, the SKF Bearing can also be installed on the conical journal with piston hydraulic nut, or the disassembly sleeve can be pressed into the predetermined position of the cylindrical journal. The composition and working principle of the piston hydraulic nut are as follows: with the help of the manual oil pump,
the pressure oil pressure is fed into the oil cylinder (nut) through the high-pressure hose, the oil cylinder is fixed on the threaded shaft end with its internal thread, the extended end of the piston is pushed on the end face of the inner ring of the SKF Bearing, the pressure oil drives the piston to push the SKF Bearing forward along the conical journal,
and according to the pressure of the oil pressure gauge in the pipeline, The thrust of SKF Bearing can be roughly judged.
