The VARITRON® Cycloid Drive unique cycloid gear design has advantages superior to speed reducers using common involute tooth gears. The key to VARITRON®'s Cycloid Drive matchless performance and reliability is that 67% of the reduction components are in contact at all times, compared to helical gear and planetary gear designs that use only limited tooth contact. Unlike geared designs, the Varitron®'s reduction components operate in compression rather than shear, which results to withstand shock loads exceeding ratings of 500%, provide exceptional performance, reliability and long life in most seFeatures • High Efficiency Rolling Contact - All major torque transmitting components roll; they do not slide. Rolling motion contributes to minimal friction and high efficiency. Single stage efficiency approaches 93%, and double stage efficiency approaches 86%. • Durable and Long Service Life The gear tooth profile of the VARITRON® Cycloid Drive enables the sharing of the load by a number of teeth, thus not susceptible to tooth breakage. At least 66% of ring gear rollers and cycloidial disc lobes share the shock load under compression. In addition, major torque transmission components inside the VARITRON® Cycloid Drive are made of 52100 (JIS SUJ2) high carbon chromium bearing grade steel hardened to Rockwell Hardness of HRC 61~63 and with precision grinding. The end result is that Varitron Cycloid Drive are capable of withstanding intermittent shock load up to 500% of its catalog torque rating.vere applications.
