Gear reduction units is particularly applicable to mixing apparatus and methods. A motor driven gear reduction unit has two parallel shafts coupled respectively to a driving pinion gear and a driven gear meshing with the pinion gear. Pivoting the cartridge eccentrically carrying one or more pinions moves the meshing pinion clear of the low speed gear such that the cartridge can be lifted out of the drive. In a multiple reduction arrangement, pivoting also can move an intermediate reduction pinion clear of the low speed gear, enabling the cartridge to be lifted clear.

Gear Shaving Cutters are used to generate tip relief, depth crowning and lead crowning. Special profiles can be offered on the cutter to generate tip relief on the component. These are used in machine tools and metalworking machinery. These are used in cutting and finishing for any type of gear, internal/external and in spur/helical.

The gear-tooth sensors are smart sensors that learn about their targets to optimize the magnetic circuit detection. It contains a samarium-cobalt magnet, a pole piece, and a differential hall effect IC that has learning capability. These sensors can be easily used in conjunction with a wide variety of gear or target shapes and sizes. It is a solid-state speed sensor can detect the motion of various ferrous objects with some type of discontinuous surface.
