Racks are portions of a cylindrical disk with an infinite radius which has involute shaped tooth cut into its encounter. Racks mate exclusively with spur gears which have the same module, pressure position and preferably encounter width. KHK offers gear racks in many components, configurations, modules and lengths. One exclusive feature of our racks is that most are given finished ends. This kind of production allows for multiple racks to end up being butted, end-to-end, to produce one continuous amount of rack. Most of the products that we offer enable secondary operations such as reduction of the space, the adding of tapped holes, or the application of heat therapy. Our offering also includes products that have already had a few of these secondary operations completed.
The straight tooth cylindrical gear for which the radius of the pitch cylinder is infinite and in a bar form is named a gear rack. If it’s sorted by the positions of the gear shafts, it is one of the parallel shaft category. The spur gear that meshes with a equipment rack is normally called a pinion.

Besides equipment racks with straight collection the teeth, there are helical racks that have slanted tooth. Helical equipment racks are paired with helical gears, but because of the slant of the tooth direction, as in helical gears, the mesh creates axial thrust forces.

Among the apparatus racks’ primary applications are machine tools and transport devices so when the applications involve transmitting linear motions, they are often compared with ball screws. In those cases, the main advantages of gear racks could be named this kind of as having the ability to fulfill a heavier load through the use of bigger modules and having no length limitation by connecting gear racks with finished ends. However, an Metric Gear Rack example of the disadvantages of equipment racks contains the occurrence of backlash.

When manufacturing equipment racks, due to their bar shape, bending often outcomes. In such cases, corrective procedures using presses tend to be employed.
