Straight (spur) gear racks have straight teeth, hence the name straight (spur) gear rack. Straight gear rack needs to drive the actuators all the time, so it is a vulnerable part. in order to ensure the service life of the straight gear rack, materials with wear resistance, impact resistance and high strength should be selected for processing. 

the rotating speed of the gear rack is more higher, its service life is less shorter. Therefore, forging steel can be selected as far as possible. Because the texture, hardness and wear resistance of forged steel are better, ASTM 5140 and 1045 steel are mostly used. however, for the large module straight gear rack, its speed is lower, casting steel can reduce the production cost. Usually the customer will determine the materials for processing. In order to reduce the frequency of replacing the straight gear rack, save maintenance cost. Our engineers will recommend suitable materials for the application of cilents' requirement.

Material: 45# steel, Stainless steel  etc.

1,  Straight rack module algorithm.

A. Module (m) = tooth pitch (p) / circumference (π)

B. Tooth pitch (p) = module (m) * circumference (π)

C.  Bite centre line (Ho) = height of rack - module (m)
