Gearing (of gear units)

Gearing refers to cutting the types of teeth for the meshing which defines the central component of each individual gear unit. Each drive system calls for different gearings depending on the performance, function and transmission ratio required.
We are optimally equipped for gear cutting. In addition to gear shafts, toothed wheels, cylindrical gears, chain wheels, splined shafts and toothed belt wheels, we're also hobbing special profiles on our gear shaping machines. The tools necessary for gear cutting are specially manufactured and must be adapted to the particular cutting machine. Using our modern gear cutting centers, we machine gears up to a 400 mm diameter and up to Module 8.
In engineering, gear cutting or shaping simply means furnishing a workpiece with splines, teeth, grooves, etc with machines. Gears are cut to establish a connection or for use as a separating tool. Whereas gear cutting is defined as a production process, gearing refers to the shape and application of the teeth.
Basically, there are three main types of gearing: spur gearing, helical gearing, and double helical gearing. For example, spur gearing is characterized by the absence of axial thrust and is also the most efficient type of gearing.
Spur gears also tend to be noisier and are more susceptible to damage from impact.
Helical gearing, on the other hand, is often used in polymer applications, whereas double helical gearing reduces pulsations compared to the other two gearing types. These two gearings are both quieter than spur gears, which is a major advantage for the end product. Nevertheless, the axial forces generated by helical gears must be supported by appropriate bearings in the gear unit.
Spur and helical gearing have a high volumetric efficiency, whereas the volumetric efficiency of double helical gearing is much lower. 
Based on various cutting production processes using milling cutters, hobs and cutting wheels, we will be cutting the gearing you want on the workpieces. The gear cutting technology that is ultimately used depends on the geometry and size of the gear as well as the position of the gearing.
Thanks to our versatile and highly stable gear cutting tools, we’re able to respond to rush orders and schedule changes flexibly and within the shortest possible time. Shaping individual parts for internal or external gearing is no problem, thanks to our highly flexible CNC hobbing machines.
In practice, gears are cut using the latest CNC gear shaping machines.
Thanks to state-of-the-art production technology, we can easily meet the highest requirements for quality in hobbing spur gears and gear shafts.
Automatic loading systems ensure maximum efficiency that is reflected in an excellent cost-benefit ratio.
