Overwiev

Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well.

Gleason system

The “GLEASON” system range of bevel gears with spiral toothing is an extension of the range of standard bevel gear pairs with which this range shares the declared intentions and objectives.

Spiral bevel gears

The spiral toothing complying with the “GLEASON” system is the result of a specific project designed to achieve optimised functional features compared with the geometric parameters that frequently conflict with each other.

Straight bevel gears

Features - Gleason system

The choice of a reduced tooth height - Correction by profile displacement
Adoption of a normal pressure angle: an = 20°
The constant tooth bottom gap along the whole tooth surface and other geometric solutions. This series of bevel gear with spiral toothing is designed for general use in plants and in general mechanical applications.

Features - Spiral bevel gears

Features - Straight bevel gears

The coupling conditions between the pinion and the ring gear are improved.
A smoother motion transmission is assured.
Tooth resistance is increased.
The undercut effect on the pinion is avoided, even in the case of high transmission ratios and pinions with a limited number of teeth.
