Planetary Gearhead

VGM planetary gearheads provide up to 3 times the torque capacity than that of conventional spur gearhead. These are compatible with any make of servomotor. The torque transmitted by the sun gear is equally distributed through the planet gear, each planet gear carries one third of the torque and the resultant forces cancel each other to yield a resultant load equal to zero hence longer life. The gearheads come with factory installed grease that is circulated continuously during the operation and lubrication refilling is not required. For standard gearheads, a small backlash of 10-arc minute and for high precision gearhead with 3-arc minute. The less noise (low decibel) finds the suitability for most of the application. The gear reduction can be from 3 to 1000 and the torque range of max 45 kgf.m. VGM planetary gearheads are available in models MF70, MF90, MF120, MF150, MF180 and PG60 7PG90. These are easy for installation and compatible with well-known servomotors in the range of 50 W-4000 W. As the planet
