The Torque - SetTM method
The principle of the Set is, under the preloaded, bearing rotation torque growth is a function of bearing preloaded force.
Operation process is as follows: first, the bearing inner surface is clean, dry and then use special impregnation resin impregnation bearing inner cavity, impregnation glue will casting casting defects such as cracks, micro seam filling after curing, and then made the outer corrosion leakage corrosion repairing adhesive processing.
The surface roughness of the workpiece can not meet the requirements of the main reason is:, screw air compressor host bearing is damaged, please come air compressor professional timely maintenance, workpiece speed too high or the workpiece axis and spindle vibration;
, normally, the temperature of the bearing with operation began to slowly rise,. . .
Reach a steady state after hours.
How to properly choose the bearing?
When choosing bearing, according to several important parameters: the bearing load, the speed of the bearing, self-aligning, allowing space, bearing installation and disassembly, tolerance grade and the price.
Repair field enterprise personnel and sauvy collaborate with technical staff, staff by the enterprise is responsible for disassembling bearing and shaft surface processing, including surface oil removal and surface grinding, sauvy technical staff responsible for on-site equipment repair process recovery bearing the size of the work, the field is more smooth, 2-seeded hour bearing a repair work is complete.

After hot working such as malleable cast stainless steel bearing, the surface often has a layer of oxide skin, lubricant, or oxide pollution pollutants including carbon graphite, molybdenum sulfide and oxide, etc.
Motor open phase discrimination methods: adopting the table measuring voltage of the power cord, whether no pressure drop;
Check to see if the copper wire inside the power cord, two of the black power cord, power cord wire has no black intact;
Open the motor chamber, a case of two phase motor meet burned, the other remain the same.
Normal fatigue wear: due to the long running, metal material itself can produce metal fatigue and elastic deformation to plastic deformation, therefore, shaft and bearing inner ring mating surface generation gap, which lead to the relative rotation of the bearing inner ring and the shaft, cause the shaft wear and tear;
。
Roundness error deviation -
Methyl amino acetonitrile fromcircularfrom measured contour of the path to the distance between two concentric circles, for roundness error.
Clean whole eccentric bearings and related parts, (
Grease to have overall eccentric bearing and oil seal or dust cover on both sides, seal the eccentric bearing without cleaning before installation.
Then fixed on the bearing seat, bearing cover, together with the bearing shell and can be mixed with impurities in the lubricating oil deposited into the chute, and is usually called 'junk slot.
Example: the WS, bearing stiffness is normal, and the natural frequency of vibration of the bearing is mostly higher than times working speed, the electromagnetic vibration force does not induce severe vibration frequency doubling, rear behind code post code in the basic code, P -

Tolerance grade meet the requirements of standard ISO level (
Do not include tapered roller bearing)
