The Cycloidal Drive unique cycloid gear design has advantages superior to common involute tooth gears system speed reducers.
Cycloidal 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 severe applications.
- Durable and Long Service Life
The gear tooth profile of the VARITRON Cycloidal 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 cycloid disc loves share the shock load under compression. In addition, major torque transmission components inside the VARITRON Cycloidal Drive are made of 52100(JIS SUJ2) high carbon chromium bearing grade steel hardened to Rockwell Hardness of HRC 61~63 andwith precision grinding. The end result is that VARITRON Cycloidal Drive are capable of withstanding intermittent shock load up to 500% of its catalog torque rating.
- High Efficiency
Rolling Contact-All major torque transmitting components roll; they do not slide. Rolling motion contributs to minimal frication and high efficiency approaches 93%, anddouble stage efficiency approaches 93%, and double stage efficiency approaches 86%.
- Simple Maintenance
Lifetime grease lubrication or easy-to-replenish oil lubrication.
Standard gray cast iron(JIS FC25) iron provides rigid structural integrity. Optional ductile iron housing(JIS FCD45) available.
- Output Shaft
High Strength Low Alloy Stell(JIS SCM21) with oversized bearings for excellent overhung load capacit and outstanding performanc.
- Dual Lips Oil Seal
Keeps lubricant in; keeps dirt out. (for flange model 8165 and above double dual lips oil seal on output side)
- Side Window (Oil Lubricate Models)
For easy oil level and clarity reading. Installing side can assign on ordering. Markers also on the side window to show how mcuk oil to fill.
- BREATHER FILLER CAP
Large oil filler hole. Oil cap also functions for pressure release purpose.
- Drain Plugs (Oil Lubricated Models)
Magnetic drain plugs design to prevent any steel dust from bearingor gear when wear in the oil. Drain plugs on double side for simple oil replavement.
