Applications for innovative markets
Gearbox (also called gearhead)
A gearhead mechanism capable of increasing torque by reducing the motor speed. An approximate value can be calculated using the following equation. The reduction ratio has been established for each model. Please see the pages of products.
Gearbox Structure
Gearboxes are roughly divided into two types of structures. Planetary Gearhead
Gear Efficiency
Gearheads have mechanical loss (gear meshing, bearing friction, etc.). Generally, for each meshing of one stage, an efficiency of 81% for planetary gears and 90% for spur gears is used in calculation. The gear efficiency, however, varies largely depending on such factors as motor torque and speed therefore is presented as a reference value. When used at a lower torque, the efficiency will drop significantly.
An example of calcuation of efficiency
- Spur gear 3-stage meshing
- Planetary gear 2-stage meshing
Backlash
The amount of gearheads backlash depends on a play required for smooth meshing and a play between the shaft and the bearing. Note, however, it increases under load due to elastic deformation.
