GEF-ES Radial Spherical Plain Bearings Features

Spherical plain bearings have a variety of measures to prevent cage noise.The raceway should be guided by the ring as far as possible and the guide surface should be sufficiently lubricated to improve the bearing structure under the condition of high speed. The raceway guided by the roller should be changed into the raceway guided by the rim of the ring.When the bearing rotates at high speed, the vibration amplitude of the cage of the bearing with large hole clearance is much larger than that of the cage with small hole clearance, so the value of the hole clearance is particularly important.Be careful to minimize the radial clearance.The improvement of the manufacturing precision and the surface quality of the cage is beneficial to reduce the noise caused by the collision or friction between the rolling body and the cage.Actively adopt advanced cleaning technology to effectively and thoroughly clean the products after parts and sets, and improve the cleanliness of bearings.The bearing operates under the action of radial load, and only a number of rolling bodies bear the load inside. The spring bearing formed by elastic contact with the ring causes the rolling body to generate periodic vibration through the action line of radial load, and the center of the rotating shaft therefore moves vertically or horizontally up and down, and at the same time causes noise.This kind of vibration is called rolling body through vibration, especially at low speed operation is more obvious.The amplitude is related to the type of bearing, the radial load, the radial clearance and the number of rolling bodies.Usually the amplitude is small, if the amplitude is large before the formation of harm, this is often used to reduce the radial clearance or apply the appropriate preload to reduce.Influence of working temperature on bearing life the size of the bearing will change with the change of material structure during working.This transition is affected by temperature, time and stress.Bearing materials must undergo special heat treatment in order to avoid unallowable dimensional changes due to structural changes in the materials.According to different types of bearings, the standard bearings are made of quenched and induction quenched steel. The highest operating temperature is directly related to the process of heat treatment.If the normal operating temperature is higher than the recommended maximum temperature, the bearings with higher stable series should be selected.If the bearing needs to work continuously at high temperatures, the bearing's dynamic load capacity may need to be adjusted.
