Racks and Spur Gears



Racks and Spur Gears

If  power transmission is carried out  by gear coupling, module transmission must be used. Usually the module identifies the type of the gear and it is the ratio between pitch and p. Module changes according to the pitch. Here following the conversion table.

Pitch     Module
3,1416 1
4,7124 1,5
6,2832 2
7,8540 2,5
9,4248 3
12,5664 4
15,7080 5
18,8496 6
25,1328 8

Spurgears with or without hub and racks are manufactured according to DIN 3962, DIN 3963, DIN 3967 regulations. The material used for gear power components is steel C45 according to UNI EN 10083-1 regulations.

The function of bevel gears consists not only in gear reduction (according to ratio) but also  90 ° misalignment of rotation axes. Items with following ratio are available in our stock:
1:1
1:2
1:2,5
1:3
1:3,5
1:4
We can also supply gears with toothing according to UNI 6588 regulations ( we call it type A) or with toothing according to “Gleason System” regulations ( we call it type B).
