Planetary gear reducer _ Runchi reducer (certified) _ Jinnan gear provided by the Texas Runchi reducer Limited. Texas Runchi reducer Limited (www.sddzjsj.com) is specialized in the "reducer, lifts, reducers, gear parts" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Zhang Yan. History of the development of China's slowdown in the industry for nearly 40 years, in various fields of national economy and defense industry, reducer products have a wide range of applications. Food and light industry, electrical machinery, construction machinery, metallurgical machinery, cement machinery, environmental protection machinery, electronic appliances, road construction machinery, irrigation machinery, chemical machinery, mining machinery, transportation machinery, building materials, machinery, rubber machinery, petroleum machinery and other industries on Reducer product has strong demand. 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 sub roll worm reducer, while increasing the roller diameter pillar and pillar holes to increase pillar and the overall strength of the cage. Improvement compared with the previous gear bearing static load rating is roughly equal, 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, although slightly lower, but effectively reduces the impact force of the roller and the holding frame between the supports of the reducer, 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 faces the end face corresponding to optimize the design of the holding frame, first, the inner, outer radial end face beveled at an angle, in order to facilitate grease into the roller strut holes, improving pillar and pillar holes between the rollers friction; reduce cage and roller end contact area planetary reducer, gear manufacturers to improve the contact characteristics to avoid burns due to excessive friction caused by cementation phenomenon. Secondly, the welded part of the original pillars of welding hole sink hole to form chamfered to enhance the welding strength, avoid sealing off.
