Racks are portions of a cylindrical disk with an infinite radius which has involute shaped the teeth cut into its encounter. Racks mate specifically with spur gears that have the same module, pressure position and preferably encounter width. EVER-POWER offers equipment racks in many materials, configurations, modules and lengths. One exclusive feature of our racks can be that most are supplied with finished ends. This type of production permits multiple racks to be butted, end-to-end, to produce one continuous amount of rack. Many of the products that people offer allow for secondary procedures such as for example reduction of the distance, the adding of tapped holes, or the use of heat therapy. Our offering also contains products that have already had some of these secondary functions completed. These products are recognized by a “J” in their part number and they are obtainable within 10 calendar times.
The straight tooth cylindrical gear for which the radius of the pitch cylinder is infinite and in a bar form is called a gear rack. If it is sorted by the positions of the apparatus shafts, it is one of the parallel shaft category. The spur gear that meshes with a gear rack is generally called a pinion.
Besides gear racks with straight collection tooth, there are helical racks which have slanted the teeth. Helical equipment racks are paired with helical gears, but due to the slant of the tooth path, as in helical gears, the mesh produces 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 generally weighed against ball screws. In those situations, the main benefits of gear racks can be named this kind of as being able to fulfill a heavier load by using larger modules and having no duration limitation by connecting equipment racks with finished ends. However, a good example of the disadvantages of gear racks includes the occurrence of backlash.
When manufacturing equipment racks, because of their bar form, bending often outcomes. In these cases, corrective processes using presses are often employed.
As for the kind of gear racks, aside from the usual bar form, there are circular racks where the cross sections are circular and flexible racks which can be bent into totally free curve shapes.
EVER-POWER share racks are created for high precision linear motion applications. We offer 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 strength and precision in the EVER-POWER standard rack series. Bolt holes could be remachined as carburizing is certainly applied only within the tooth region. J Series products are also available.
Hardened Floor Racks (KRGF-H – KRGFD-H)
Heat treated surface gears with high precision and power has superb cost-performance ratio. J Series products are also available.
Steel Racks (SR)
Low cost, large selections of modules and quantity of teeth. J Series items are also available.
STAINLESS Racks (SUR·SURF·SURFD)
Suitable for food machinery due to SUS304 material\’s rust-resistant quality.
Brass Racks (BSR)
Small pitch racks made of free-cutting brass, excellent workability and high rust resistance.
Gear racks are used to convert rotating motion into linear motion. A equipment rack has straight the teeth cut into one surface area of a square or round section of rod and operates with a pinion, which is usually a small cylindrical gear meshing with the apparatus rack. Generally, equipment rack and pinion are collectively known as “rack and pinion”. There are several ways to use gears. For example, as demonstrated in the picture, a gear is used with the gear rack to rotate a parallel shaft.
To provide many variations of rack and pinion, Ever-power has many types of gear racks in stock. If the application takes a long duration requiring multiple gear racks in series, we’ve racks with the tooth forms properly configured at the ends. These are described as “equipment racks with machined ends”. When a equipment rack is produced, the tooth cutting procedure and the heat treatment process can cause it to try & go out of true. We are able to control this with special 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 as the gear rack moves. The previous is used widely in conveying systems while the latter can be utilized in extrusion systems and lifting/lowering applications.
As a mechanical component to transfer rotary into linear movement, gear racks are often compared to ball screws. There are advantages and disadvantages for using racks instead of ball screws. The advantages of a gear rack are its mechanical simplicity, huge load carrying capacity, and no limit to the distance, etc. One disadvantage though is the backlash. The advantages of a ball screw are the high precision and lower backlash while its shortcomings include the limit in length 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 several shafts in general industrial machinery. However, they are also used in steering systems to change the direction of vehicles. The characteristics of rack and pinion systems in steering are the following: simple framework, high rigidity, small and lightweight, and excellent responsiveness. With this system, the pinion, mounted to the steering shaft, is usually meshed with a steering rack to transmit rotary movement laterlly (switching it to linear motion) so that you can control the wheel. In addition, rack and pinions are used for many other purposes, such as playthings and lateral slide gates.

Gear rack, when used in combination with spur gears, converts rotary motion into linear motion. Equipment rack from Ever-power is designed to operate with our share 14 1/2° and 20° PA spur gears.
Often, gear rack is modified to match specific applications. This might include drilling and tapping mounting holes, cutting to specific lengths or complementing ends of two bits of rack to make a continuous size longer than stock.
· Ever-power’s gear rack will come in 14 1/2° and 20° PA to suit an array of application requirements.
· Stocked in 4ft and 6ft lengths
· The choice of 48 to 3 DP meets an equally varied array of needs.
· Length tolerance allows ends to become matched for easy modification.
· Our in-share inventory of nylon, and metal ensures availability – and compatibility.
· Because it is flawlessly matched to Ever-power’s spur gears, our gear rack promises superior efficiency.
