Crown gears

advantages

A crown gear for an angle transmission

Crown toothing have many advantages:

- transmission angle between 0 and 150°,
- high reduction ratio,
- easy assembly with limited adjustments,
- possibility of backlash-free transmission,
- efficiency and noise level comparable to a parallel gears,
- no axial force,
- etc.

applications

Specific and open markets

Crown gears are used in many sectors of the industry for applications requiring efficient, compact and precise transmission:

- machine tools (rotating tools),
- 4x4 differentials ,
- double rotation systems (double propeller, etc.),
- robotics (handle),
- etc.
