Use TIMKEN bearings should be used for fatigue

1, shaft and bearing room tolerance of the choice and control: TIMKEN bearing into the bearing after the rotation should be flexible without blocking sense. If there is a clear rotation is not flexible, it indicates that the size of the shaft is too large, the tolerance to be lowered. If the shaft is confined to the shaft with the hand rotation has obvious "rustle" feeling, then it may be the axis of tolerance is too large or the axis of the roundness is not good. So in the control of the shaft and bearing room tolerance to control the roundness, many manufacturers in the country only to control the tolerance, not on the roundness control.

2, TIMKEN bearing assembly way: because the bearing is high precision products, such as improper assembly is very easy to cause damage to the bearing channel, resulting in damage to the bearing. Bearing in the assembly should have a special mold, not random beat, in the pressing axis can only be a small circle force, pressing circle circle only force. When the assembly requires the use of pneumatic or hydraulic pressure, when the pressure in the upper and lower mold to be outside in the horizontal state, if there is a tilt will cause the bearing channel due to damage, and to produce a guide bearing.

3, the assembly of foreign bodies to prevent Timken bearings mounted to the rotor dynamic balance easily the dynamic balance of iron into the Timken bearing, so it is best to before installation of the bearing dynamic balance. Some manufacturers in order to facilitate the assembly and assembly on the bearing interior painted some oil or grease on the lubrication effect, but often the operator is difficult to control, if the oil or grease in the Timken bearing chamber product more in bearing rotates easily along the shaft into the bearing. The bearing room is not the best oil or grease, such as non coating is not available to control not in the bearing interior accumulates.

4, paint, rust prevention, rust paint is multiple in sealing type motor, motor assembly sound good, but inside the warehouse put some time after motor abnormal sound becomes very large, removal of Timken bearings have serious rusting phenomenon. Before a lot of manufacturers will consider the issue of bearing, through our continuous publicity, and now the motor plant has been aware of the problem is mainly insulation paint. The problem is mainly due to the insulating paint volatile acid substances in a certain temperature, humidity, the formation of corrosive substances, the TIMKEN bearing channel corrosion caused by damage to the bearing. The problem can only be used as a good insulation paint, and ventilation after a period of time after the assembly.

TIMKEN bearing life is closely related to the manufacture, assembly and use, must be done in each link, in order to make the bearing in the best running state, thus prolonging the life of TIMKEN bearing.

According to TIMKEN bearing fatigue life calculation of fatigue life delineated, the inner ring or shaft rotation (in this case, the outer ring or the seat is fixed) the delineation of the calculation, the total value of the transfer of the total transfer value.

Move bearing fatigue life test procedures, standard test method and test machine function of a way in, delineated in order to satisfy the requirements, the number of Timken bearing fatigue life test samples, from the test data obtained actual test life. That is to say, bearing fatigue test subjects reveal a life.

Bearing fatigue life test is sufficient lubrication, utmost ground restrains move bearing wear, and enhance the capacity and speed, to uplift the Timken bearing fatigue factor enhanced fatigue life test method.

TIMKEN bearing fatigue life of the calculation and fatigue life test is complementary to each other, the two result is enough to the letter.

In fact, if every detail, have taken the full number of Timken bearing life test, to verify the suitability of the selected bearing on economic time and the amount of labor and, therefore, bearing life test method is is necessary or important, in most circumstances, in the use of, the calculation method of a scale estimated Sweden Timken bearing life life, adequate levels of reliability.
