This photo shows a gear, which is also called a spur gear.
A gear is used in almost all mechanical drives to transmit forces. The required tooth size, also called module, tooth width (also called tooth flank) and the number of teeth depend on the space in the mechanical drive / gear and the force to be transmitted, which is also called torque.
The material of the gear must be selected depending on the load. Steels that can be hardened are usually used. Depending on the hardening process, the steel inside the tooth is still soft and the surface of the teeth is hard (wear-resistant). A particularly popular material for gears to be hardened is 16MnCr5.
Depending on the desired accuracy or tolerance (gear quality), the teeth of a gear can be milled and, if necessary, ground. Milling achieves tolerances in the hundredths of a millimeter range. Grinding achieves tolerances in the µ range (thousandths of a millimeter range).
Whether a gear has achieved the desired geometry is checked by measuring machines (tooth flanks, tooth pitch, shape and position tolerances, dimensional tolerances). There is also the option of checking the gear for grinding burn.
As every mechanical drive is different, we do not have any stock items. We only manufacture to order, in single or large series. We manufacture gears according to your requirements – be it by milling, grinding or shaping, as well as straight toothed or helical toothed in module 0.3 – 18.
