Small machines can be rotated by hand to confirm whether they rotate smoothly

Small machines can be rotated by hand to confirm whether they rotate smoothly. The temperature of the bearing gradually increases from the start of operation, and usually stabilizes after 1 to 2 hours. Check for vibration, noise, contact with rotating parts, etc. At the same time, care must be taken to maintain the cleanliness of the bearing. Correct installation and maintenance are important factors for the normal operation of the bearing., indicating abnormality.

The inspection items include improper operation due to foreign objects, scars, and indentations, unstable torque due to poor installation and poor processing of the mounting seat, excessive torque due to too small clearance, installation errors, and seal friction. In the case of high-speed rotation, the wrong choice of imported bearing structure and lubrication method is also the reason. If an abnormality is found, stop the operation immediately, inspect the machine, and remove the bearing for inspection if necessary.

In addition, the experts of the bearing trading network believe that the design of the bearing arrangement, the condition of the oil seal, the form of the lubricant and the replacement cycle and the special maintenance also play an important role and must be paid attention to.. Large machinery cannot be rotated manually, so immediately cut off the power after starting no-load, and the machinery runs idly. 1. If there is no abnormality, power operation can be started.

Bearings must be protected from contaminants and moisture, and must be properly installed and lubricated. The reasons include too much lubricant, too small bearing clearance, poor installation, and too much friction in the China wheel bearing kits sealing device. The power operation starts at a low speed with no load and slowly increases to the rated operation under the specified conditions., there are strong metal noise, abnormal sound, irregular sound, etc.

The reasons include poor lubrication, poor shaft or bearing seat accuracy, bearing damage, and foreign matter intrusion. Wait. However, it is more accurate to use the oil hole to directly measure the temperature of the outer ring of the bearing. The bearing temperature can generally be estimated from the external temperature of the bearing seat. If the bearing is installed improperly, the temperature will rise sharply, resulting in abnormally high temperature
