Fixed KOYO bearing operation needs to pay attention to six major issues

The thermal sensor can be used to monitor the operating temperature of the bearing at any time, and automatically alarm or stop the occurrence of a burning shaft accident when the temperature exceeds the specified value. The high temperature often indicates that the bearing is in an abnormal condition. High temperatures are also harmful to the lubricant of the bearing. Sometimes the bearing overheating can be attributed to the KOYO bearing lubricant. Long-term continuous rotation of the bearing at temperatures above 125 °C will reduce bearing life. Causes of high temperature bearings include: insufficient lubrication or excessive lubrication, lubricants. Contains impurities, excessive load, bearing damage, insufficient clearance, and high friction caused by oil seals.

Therefore, it is necessary to continuously monitor the bearing temperature. KOYO needle bearings are used to measure the bearing itself or other important parts. If the operating conditions are the same, any temperature change can indicate that a fault has occurred. The periodic measurement of the bearing temperature can be accurately measured by means of a thermometer, such as a digital thermometer, and displayed in °C or Fahrenheit.

The temperature of the bearing is generally estimated by the temperature outside the bearing. If the oil hole can directly measure the temperature of the bearing outer ring, KOYO bearing is more suitable. Usually, the temperature of the bearing rises slowly as the bearing starts to run, and reaches a steady state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormal temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions.

Shoulder shoulder fixation

KOYO bearing inner ring is axially fixed by shoulder and interference. Suitable for supporting structures fixed at both ends. The structure is simple and the outer dimensions are small.

2. Retaining ring fixing

The inner ring of the imported bearing is axially fixed by the shoulder and the lock nut. Can withstand small bidirectional axial loads. The axial structure is small in size.

3. Lock nut fixing

The KOYO bearing inner ring is axially fixed by the shoulder and the lock nut. And the retaining washer is anti-loose, safe and reliable, suitable for high speed and heavy load occasions.

4. End thrust washer fixing

The KOYO imported bearing inner ring is axially fixed by the shoulder and the shaft end retaining ring. The shaft end retaining ring is screwed to the shaft end. The fixing screws should have a locking device. Applicable to occasions where the shaft end is not suitable for cutting threads or space is limited.

5. Fixed sleeve fixing

The axial fixing of the inner ring of the KOYO bearing is achieved by the radial dimension of the inner hole of the adapter sleeve being compressed and clamped on the shaft.

6. Unloading sleeve fixing

The withdrawal sleeve is clamped in the same way as the adapter sleeve. However, due to the special nut, the KOYO inlet shaft is easy to handle and disassemble. It is suitable for fixing the double row spherical bearing with large radial load and small axial load on the optical axis.

The improved design of KOYO bearing seat is mainly to ensure the normal position of the bearing seat in the frame, to prevent the axial load from being generated after the bearing seat and the frame are worn out, and also to make the support and the support as parallel as possible, which can effectively eliminate the additional eccentric moment. .

KOYO bearing seat thrust lugs add skateboards on both sides, the purpose of which is to adjust the axial clearance in time to reduce the wear on the side of the compensation thrust lugs. Use a flexible nylon cage to prevent the cage from breaking and jamming the steel ball as it invades the bearing raceway. For example, at the point of action of the bending force, the hardened and resistant hemp block is set up, and the purpose is to generate an axial additional load on the bending force. Increase the internal clearance of KOYO bearings, from the original common level to the third and fourth increased auxiliary clearance.
