Hi,

For a final drive of a light commercial truck, I have to design a final drive helical gear pair. The expected ratio is 8.2. The centre distance is 134 mm. The input max. torque is 120 Nm. I have sized few combinations.

I have a feeling that this ratio is too deep. Pl. share me your opinions and views on this. I mainly need few check-points while designing such a deep ratio helical gear pair. Thanks.

 

hi
you mean that gear ratio is 8:2 ?
center between gears is 134 mm or not?

 

Hi Mechaboy,

The gear ratio is 8.2:1. The centre distance is 134 mm. Thanks.

 

i suggest you ti use a decimal number for the module of gears,
what is the material of your gears?
what you want to do for lubrication?
what is your bearing arrangement?
