After the NSK bearing device is completed; in order to check whether the device is correct; to check the work. The small machine can be rotated by hand; to recognize whether the rotation can be smooth. Check the project for the work caused by foreign objects, scratches and indentations; The device is not good; the torque generated by the device seat is not stable; the torque is too large due to too small clearance, device error, sealing conflict, etc. If there is no abnormality, the power can be started.
Large machinery can't be rotated manually; therefore, the power is blocked immediately after the no-load start; the machine is idling; check whether there is oscillation, noise, whether the rotating parts can touch, etc.; after acknowledging that there is no abnormality; enter the power work.
Power work; start from no-load low-speed; slowly progress to additional work for the specified conditions. Check the items in the test work; whether there are abnormal sounds, changes in bearing temperature, leakage or discoloration of smoothing agents, etc. ; should work immediately; view the machine; if necessary, remove the bearing to view.
The consistency and smoothness of the grease is the NSK bearing that is operated at a certain temperature affected by the operating temperature. It is necessary to select the grease with the correct consistency and outstanding smoothness at the same temperature. The grease is made at a different working temperature scale. It can be roughly distinguished as low-temperature, medium-temperature and high-temperature grease. Together; the difference is mainly based on temperature and working conditions: grease can be classified according to its allowable working temperature. One type of grease is called kneading or kneading and increases Molybdenum sulfide; together; an increase agent is added to strengthen the strength of the smooth oil film.
