A Gear Rack or Rack Gear consists of spur gear tooth or helical gear tooth cut on a linear rectangular or circular rod. Both round gear racks and linear gear racks can be described as a sector gear with an infinitely large radius of curvature.
The most obvious usage of a spur gear rack is to convert the rotary motion of a pinion gear into linear movement or vise versa. When assembled, they are referred to as a rack and pinion. Rack gears provide an advantage over ball screws because they have a huge load carrying capacity 
and a Stainless Steel Gear Rack china straightforward design which allows linking multiple racks to meet up your required length.
We bring both rectangular and round cross-section gear rack styles in a
range of precision pitches. All our in . and metric gear racks possess machined ends for applications needing the use of multiple equipment racks in a series.
Whenever your machine’s precision motion drive exceeds what can easily and economically be performed via ball screws, rack and pinion may be the logical choice. Best of all, our gear rack includes indexing holes and installation holes pre-bored. That saves you lots of time, hassle and expenditure.
If your travel length is more than can be obtained from a single amount of rack, no problem. Precision machined ends enable you to butt extra pieces and keep on going.
A rack can be called equipment rack or just railing. They are rectangular designed rods that are given on one aspect with toothing as being a gear. By utilizing a gear that engages in the toothing of the rack, you’ll be able to move the apparatus or the rack longitudinally. Tooth racks are utilized, among other activities, in machines in which a rotational motion should be converted to a straightforward motion or vice versa.
If power transmission is carried out by gear coupling, module transmission can be used. Usually the module identifies the type of the gear and it is the ratio between pitch and p. Module changes based on the pitch. Here following conversion table.
The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also called spur gears.
