The spherical roller bearing device should finally adjust the clearance. The clearance value should be determined in detail according to the different operating conditions and the cooperative interference. If necessary, the experimental determination should be made. Bearing and pump shaft bearings The clearance has been adjusted at the factory; the device does not need to be adjusted.
The device of the spherical roller bearing needs to be carried out under boring and hygienic environmental conditions. Before the device, carefully check the cooperation appearance of the shaft and the outer casing, the end face of the shoulder, the groove and the processing quality of the joint appearance. It is necessary to carefully remove and remove the burrs; it is necessary to remove the sand from the unprocessed appearance of the casting.
Before the spherical roller bearing device, it should be cleaned with gasoline or kerosene; it should be used after boring; and it should be excellent and smooth; the bearing should be smooth and smooth; the oil should be smooth. When the grease is smooth, it should be free of impurities and anti-oxidation. Smooth grease with excellent performance such as anti-rust and extreme pressure. The filling amount of smooth grease is 30%-60% of the bearing and bearing box volume; it should not be too much. Double row tapered roller bearing and water pump shaft bearing with sealing layout have been Filled with smooth grease; users can use it directly; no more cleaning.
When aligning the roller bearing device; it is necessary to apply equal pressure on the circumference of the end face of the ferrule; press the ferrule; do not directly hit the bearing end face with the number one thing; avoid damage to the bearing. In the case of small interference Lower; the sleeve can be pressed against the end face of the bearing ring at normal temperature; the sleeve is struck with the head; the sleeve is evenly pressed through the sleeve. If it is a large-scale device; hydraulic machine can be used. The end face of the outer ring and the end face of the outer shoulder of the outer casing; the end face of the inner ring and the end face of the shoulder of the shaft are pressed; no gap is allowed.
When the interference is large; you can use oil bath heating or induction heating to install the device; the heating temperature is 80 Â°C-100 Â°C; the maximum can not exceed 120 Â°C. Together; use nuts or other appropriate means to tighten the bearing ; to avoid the shortening of the width direction of the bearing after cooling, resulting in a gap between the ferrule and the shoulder.
After the spherical roller bearing device, the rotation test should be carried out; firstly, it should be used for rotating shaft or bearing housing; if it is not abnormal, it will work without load and low speed with power; then gradually increase the rotation speed and load according to the working condition; and detect noise, Oscillation and temperature rise; found abnormal; should stop work and view. Work experiment can be delivered after normal operation.
