Straight Teeth Racks
Your Professional Straight Teeth Racks Manufacturer!
Kunshan Devotec Automation Co., Ltd. was established in 2012, but its origins trace back to an initial investment by the German company WMH HERION in Qingdao, Shandong Province in 2007. Since then, we have accumulated extensive experience in engineering, manufacturing, and quality control. As a specialist in drive technology, Kunshan Devotec Automation focuses on the production of high-precision gear racks, gears, pinions, gearboxes, linear guideways, and other linear transmission components. The company also serves as a partner for several European manufacturers in China, including , Graessner, and Hönger, providing localized sales and after-sales services.

Advantages of Straight Teeth Racks
Relatively High Precision
Straight teeth racks are manufactured with strict tolerances, ensuring accurate tooth profile and tooth pitch.
High Transmission Efficiency
The straight-tooth design enables direct power transmission when the gear meshes with the rack, with an efficiency of over 95%, which can effectively save energy.
Good Wear Resistance
Its surface can undergo treatments such as grinding and quenching, with a hardness of up to HRC 45-50. The surface is wear-resistant and smooth, not easy to break during operation, and can withstand long-term friction and load.
Strong Compatibility
The rack adopts a straight-tooth design, which is suitable for series installation. It can be combined with various types of gears and reducers, and can provide targeted transmission effects in different fields and working conditions.
Easy Installation
Some straight teeth racks are equipped with pre-drilled holes and other mounting structures on the surface, which can be quickly and firmly installed on equipment. This saves installation time and effort and simplifies the assembly process.
Applications Of Straight Teeth Racks
Material Handling and Conveyors
Straight teeth racks are ideal for low-speed conveyor systems and other material handling equipment where precision is not critical.
01
Agricultural and Construction Machinery
The simplicity and cost-effectiveness of straight teeth racks make them suitable for various agricultural and construction machines.
02
Factory Automation
They are used in automated factory processes and packaging machines where ease of installation and robustness are more important than extreme precision.
03
Machine Tools
In some machine tool applications, particularly those with lower speed requirements, straight teeth racks can be utilized.
04
Industrial Robots
For less demanding robotic tasks, straight teeth racks provide a simple and economical solution for linear motion.
05
Manufacturing process of Straight Teeth Racks
Stock Material: The process begins with raw material, often carbon steel like C45, 42CrMo, or stainless steel, depending on the application.
Blanking: The round rod material is cut to length to form a blank, which is then turned to the correct dimensions.
Gear Hobbing or Rack Cutting: The primary method for cutting teeth is with a rack cutting machine or a gear hobbing machine.
Rack Cutting: A reciprocating cutting tool shaped like the desired gear teeth cuts into the blank. The blank is rotated after each cut until the teeth are formed.
Gear Hobbing: This process uses a rotating cutter to cut the teeth, creating accurate gear profiles for external spur gears.
Deburring: Any burrs or sharp edges left from the cutting process are removed to ensure proper function.
Straightening: If the rack has warped, hydraulic presses are used to straighten the teeth.
Machining Ends and Holes: Both ends of the rack are machined for proper connection, and mounting screw holes are drilled for easier assembly.
Hardening and Tempering: The rack is subjected to heat treatment processes such as integral quenching and tempering or high-frequency quenching.
Finishing: A black oxide finish can be applied to help prevent rust and improve the rack's appearance.
Packaging: Each finished rack is individually packaged to ensure it reaches the customer in good condition.
Packaging and Shipping
1) Inner packing: rust-preventive oil application,vacuum packaging bag
2) Outer packing: wooden case or pallet
3) Customized packing is also available
4) Production Lead Time: 15-35 days after approved
