Advantages of PHT Planetary Gearboxes

High Efficiency

Planet gears are in full and constant-meshed, eliminating the possibility of gear tooth damage from gear clash or partial engagement. The full and constant-meshed feature also permits automatic and quick gear ratio changes without power flow interruption.

A typical efficiency loss in a planetary gearbox arrangement is only 3% per stage. This type of efficiency ensures that a high proportion of the energy being input is transmitted through the gearbox, rather than being wasted on mechanical losses inside the gearbox. Efficiency better than harmonics, can be over 90% in some cases.

Greater Stability

Due to the even distribution of mass and increased rotational stiffness, the arrangement of planetary gearbox also creates greater stability.

Compact Size

Planetary gear units share a common axis, which results in a more compact structure than traditional devices.

Higher Torque Density

Higher torque density, as well as greater load ability, is obtained with mroe planet gears in the system.

Cost Effective Precision

PHT planetary gearboxes offer a much more competitive price point than our competitors' gearing options.

High Radial Loads

Planetary gears are strong and sturdy, which can handle larger torque loads, for the compact size, in comparison to other gear combination in manual transmissions. This is because the torque load, as it passes through the planetary set, is distributed over the several planet pinion gears, which allows more tooth contact area to handle the power transmission.
