How we work

Venturi srl main activity is manufacture hypoid, spiral and Zerol crown wheel & pinion sets and Curvic Coupling, that we cut with the Gleason System.

Starting by customer specification (drawing or sample) we can produce or teeth and lap the crown & pinion sets .

TECHNICAL DEPARTMENT:

The work of the technical dept. begins after the customer enquiry, choosing the working process, the equipment and the tools to be used.

After order confirmation our process stages are:

A ricevimento dell'ordine dal Cliente le procedure interne prevedono:

Studio della dentatura conica tramite collegamento diretto con la Gleason ( Dimension Sheet, TCA, Summary )

Study of the bevel cut (dimension sheet, TCA, summary) performed using a software connected to Gleason
Tooling study
equipments engineering (CAD)
Working process
drawings

MANUFACTURING PROCESS:

The ring gear production capacity range is from 6” to 22” diameter, with Modul 3-12 and with original Gleason cutter blades from 3,5” to 16”. The teething of the “formate” crown and pinion sets is carried out with the Gleason machines type 11, 112, PH600 and 22, whereas the “generated” gear sets are cut with Gleason 116 and PH600 also used for the pinions. The newly acquired Phoenix 600HC is used for the “completing” type cut.

All the ring and pinion set are lapped using Gleason lappers type 503, 506, 516 and then tested one by one on Gleason tester type 502, 512, 513, 17H and 17A.

QUALITY CONTROL:

Venturi srl may assure to the customers all the quality requirements .

Using up-to-date measuring instruments like a 3D ZEISS center Mod. ACCURA to check the parts, we can obtain an high quality level. We can supply several quality certificates like dimensional measurement, evaluation of flank form, pitch, tooth thickness, spiral and profile angle of Involute Spiral Bevel Gears according to DIN 3965, part 1 and 2, AGMA 390.03a, Rev. 1988 and ANSI/AGMA 2009-A98, steel certificate and heat treatment test.
