Planetary Gearbox PG planetary gear units are divided into 21 basic groups depending on the different torques that are to be transmitted to the output shaft, which can vary from 0,05 to 1.280 kNm. In fact, the product modular construction permits the coupling of bevel gears, worm gears,...

The planetary reduction drive is based on an classic but ingenious design. It is based on a system of ball bearings rolling between two surfaces while housed within a rotating bushing. The planetary reduction drive is often used to enhance the fine-tuning control of a variable capacitor. For...

These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of a coreless motor fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal...

On the surface, it may seem that gears are being “reduced” in quantity or size, which is partially true. When a rotary machine such as an engine or electric motor needs the output speed reduced and/or torque increased, gears are commonly used to accomplish the desired result. Gear “reduction”...

Raydafon DC Planetary gearmotors are an inline option for low speed, high torque, and/or variable load requirements. These gear motors are designed for intermittent duty operation because the planetary gearbox configuration provides the highest efficiency and best output torque of all our...

Planetary gear reducers belong to the epicyclic family of reducers, since the planet gears trace epicycloidal curves in space—very similar to how the popular kid’s toy, the spirograph, works[i]. Simple planetary gears are arranged with a centrally located, externally toothed sun gear that meshes...
