Reduce the impact force to keep the roller frame and between the pillars. In the main gear bearing design parameters when changing gear bearing the pursuit of maximum rated load of conventional design methods, reducing the diameter of the roller and increase the number of rollers, while increasing the roller diameter pillar and pillar holes to increase pillar and cage overall strength. Improvement compared with the previous gear bearing static load rating is roughly equal planetary reducer, dynamic load rating is reduced, is still able to meet the needs of practical work gearbox bearings, and roller weight decreased and, rated load bearing gear though slightly reduced, but effectively reduces the impact force of the roller holding frame and between the pillars, the pillars extend life, and because the roller diameter decreases, a corresponding increase in the wall thickness of the ferrule can be improved impact resistance reducer bearing. Thus delaying the holder of the expiration time, extending the gear bearing life. To improve the welding strength. Increasing the use of weld puddle forms the steps to strengthen the bond strength; abandon common thread undercut, with smaller threads to achieve a natural transition ending, the force decreases pillar stress concentration and welding parts thread tail. In addition, the roller end corresponding to the end face of the inner frame to maintain optimal design, the first rv reducer, inside and outside diameter of the end face of the miter angle to facilitate the grease into the roller pillar holes, improving pillar and pillar holes roller friction between; reduced cage and roller end contact area, improve the contact properties, to avoid burns caused by excessive friction, the phenomenon of cement. Secondly, the welded part of the original pillars of welding hole sink hole to form chamfered to enhance the welding strength, avoid sealing off. Reducer generally used for low-speed high torque transmission device, the motor, the internal combustion engine or other power high speed input shaft by a small number of teeth meshing gear reducer output shaft of the gear reducer to achieve the purpose of reducer, ordinary gear will have several pairs of the same principle to achieve the desired deceleration effect gear reducer model than the size of the gear teeth, is the transmission ratio. The main difference with the drive gear difference: gear mechanical transmission by reducing the motor (motor) speed, but the frequency by changing the frequency of the alternating current motor to achieve (motor) speed control purposes. By reducing the motor speed when the inverter can achieve energy saving. Worm gear reducer _ _ Changsha Runchi gear provided by the Texas Runchi reducer Limited.
