Racks are portions of a cylindrical disk with an infinite radius which includes involute shaped the teeth cut into its encounter. Racks mate specifically with spur gears which have the same module, pressure position and preferably face width. EVER-POWER offers equipment racks in many materials, configurations, modules and lengths. One exclusive feature of our racks can be 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 people offer allow for secondary functions such as for example reduction of the distance, the adding of tapped holes, or the application of heat therapy. Our offering also contains products that have already had some of these secondary functions completed. These products are determined by a “J” within their part number and they are offered within 10 calendar days.
The straight tooth cylindrical gear that the radius of the pitch cylinder is infinite and in a bar form is called a gear rack. If it’s sorted by the positions of the apparatus 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 tooth, there are helical racks which have slanted tooth. Helical equipment racks are paired with helical gears, but due to the slant of the tooth direction, as in helical gears, the mesh generates axial thrust forces.
Among the apparatus racks’ primary applications are machine equipment and transport devices and when the applications involve transmitting linear motions, they are often weighed against ball screws. In those cases, the main benefits of gear racks can be named such as having the ability to meet a heavier load by using larger modules and having no length limitation by connecting equipment racks with completed ends. However, an example of the disadvantages of equipment racks contains the occurrence of backlash.
When manufacturing equipment racks, because of their bar shape, bending often outcomes. In these cases, corrective procedures using presses tend to be employed.
As for the form of gear racks, aside from the usual bar form, there are round racks where the cross sections are circular and flexible racks which can be bent into free curve shapes.
Racks Categories
EVER-POWER stock racks are created for high precision linear motion applications. You can expect a large collection of racks ranging from module 0.5 to 10 and lengths from 100 to 2000 mm.
Hardened Floor Racks (MRGF – MRGFD)
Has the highest power and precision in the EVER-POWER standard rack series. Bolt holes could be remachined as carburizing is applied just within the tooth region. J Series products are also available.
Hardened Surface Racks (KRGF-H – KRGFD-H)
Heat treated ground gears with high precision and power has superb cost-performance ratio. J Series products are also available.
Steel Racks (SR)
Low cost, huge selections of modules and number of teeth. J Series items are also available.
Stainless Steel Racks (SUR·SURF·SURFD)
Suitable for food machinery because of SUS304 materials\’s rust-resistant quality.
Brass Racks (BSR)
Small pitch racks made of free-cutting brass, superb workability and high rust resistance.
Gear racks
Gear racks are used to convert rotating movement 
into linear movement. A gear rack has straight tooth cut into one surface of a sq . or round portion of rod and operates with a pinion, which is certainly a small cylindrical equipment meshing with the gear rack. Generally, gear rack and pinion are collectively called “rack and pinion”. There are numerous ways to use gears. For instance, as shown in the picture, a gear is used with the apparatus rack to rotate a parallel shaft.
To provide many variations of rack and pinion, Ever-power has various kinds of gear racks in stock. If the application requires a long length requiring multiple equipment racks in series, we have racks with the tooth forms properly configured at the ends. They are described as “gear racks with machined ends”. When a equipment rack is produced, the tooth cutting process and heat treatment process could cause it to try & go out of true. We can control this with particular presses & remedial processes.
There are applications where in fact the gear rack is stationary, while the pinion traverses and others where in fact the pinion rotates upon a fixed axis while the gear rack moves. The previous is used widely in conveying systems as the latter can be used in extrusion systems and lifting/lowering applications.
As a mechanical component to transfer rotary into linear motion, gear racks are often compared to ball screws. There are benefits and drawbacks for using racks in place of ball screws. The benefits of a gear rack are its mechanical simplicity, huge load carrying capacity, no limit to the distance, etc. One drawback though is the backlash. The benefits of a ball screw will be the high precision and lower backlash while its shortcomings are the limit in duration due to deflection.
Rack and pinions are used for lifting mechanisms (vertical movement), horizontal movement, positioning mechanisms, stoppers and to let the synchronous rotation of many shafts in general industrial machinery. However, also, they are used in steering systems to improve the direction of vehicles. The characteristics of rack and pinion systems in steering are as follows: simple structure, high rigidity, little and lightweight, and excellent responsiveness. With this mechanism, the pinion, mounted to the steering shaft, is certainly meshed with a steering rack to transmit rotary motion laterlly (converting it to linear movement) so that you can control the wheel. In addition, rack and pinions are used for many other purposes, such as toys and lateral slide gates.

Gear rack, when used in combination with spur gears, converts rotary movement into linear motion. Gear rack from Ever-power is designed to operate with our share 14 1/2° and 20° PA spur gears.
Often, equipment rack is modified to fit specific applications. This might consist of drilling and tapping mounting holes, cutting to specific lengths or matching ends of two bits of rack to make a continuous duration longer than stock.
· Ever-power’s gear rack comes in 14 1/2° and 20° PA to suit a wide variety of application requirements.
· Stocked in 4ft and 6ft lengths
· The choice of 48 to 3 DP meets an similarly diverse array of needs.
· Length tolerance enables ends to end up being matched for easy modification.
· Our in-stock inventory of nylon, and steel ensures availability – and compatibility.
· Because it is perfectly matched to Ever-power’s spur gears, our equipment rack promises superior functionality.
