Bevel gear sets

Oerlikon Graziano is a leader in the manufacturing of bevelgears applying all the technologies available on the markettoday.

Oerlikon Graziano has three modern and specialised plants forcrown wheels & pinions (CWP) production (Sommariva Perno and

Porretta - north of Italy; Delhi - India).

Both Gleason and Oerlikon Klingelnberg (Palloid method

included) technologies are available at OGs facilities: continuousand not continuous indexing methods are widely used for more

than 250 different bevel sets.

Oerlikon Graziano has the technology to cut the parts (soft stage

before heat treatment) in wet and dry condition that correspondto the traditional way of machining (wet) and to the most updatedmethod using Carbide tools (dry Power Cutting). HSS and

Carbide blades can be accommodated on sharpening machinesin order to have the full process in house (coating is an outsidesource but still within Oerlikon Group through Oerlikon Balzers).

Oerlikon Graziano can machine parts (after heat treatment) byapplying grinding and/or lapping process. The most updatedmachines are available: Gleason 200G/275G, Gleason 800,Oerlikon WNC50 (for Semicompleting); Gleason 600HTL andOerlikon L50.

It is remarkable that UMC sets (ground only) can beaccommodated on all the Gleason grinding machines inorder to have a very fine tuning of the microgeometry inview of noise and durability optimization.

For static inspection of the parts Oerlikon Graziano has CMM(Zeiss) running with G-Age and Komet software. For matchinginspection Oerlikon Graziano has several Gleason testers andthree Single Flank testing equipments for objective analysis(transmission error is a standard parameter used both at theprototypes stage and in mass production environment).

Especially for the lapped sets and because of the heattreatment influence (distortions) Oerlikon Graziano hasan internal procedure that allows to monitor continuallythe consistency of the process and to develop the desiredcontact pattern. A specific and well trained team worksdaily to develop new jobs and to assist production in caseof any kind of quality issue.

Even if the bevel sets are one of the core product of the companysince a long time ago it is remarkable that Oerlikon Grazianohas been dispatching more than half million sets every

year since 2000.

Oerlikon Graziano also has Gleason technology to cut straightgears (i.e. for diff housing applications) in both Coniflex andRevacycle methods. Furthermore net forged straight gears canalso be supplied if required.
