Flexible Gear Rack

Flexible plastic equipment racks in 0.8 Mod (32DP) pitch. These racks can provide an easy to set up rotational drive of up to approx 270 degrees for example on camera focus rings. They also provide an economical remedy where a large gear is required or a longer stretch (up to 2 metres) of linear movement is desired. These racks are compatible with our 0.8 Mod and 32 DP pitch Spur Gears.
EVER-POWER stock racks are made 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 Surface Racks (MRGF – MRGFD) : Gets the highest power and precision in the EVER-POWER standard rack series. Bolt holes could be remachined as carburizing is definitely applied only within the tooth region. J Series items are also available.

Brass Racks (BSR) : Little pitch racks made of free-trimming brass, excellent workability and high rust resistance.
Steel Round Racks (SRO – SROS) : Convenient in applications where in fact the rack gets the reciprocal movement. S Type is easy to install.
Stainless Steel Circular Racks (SURO) : Same dimensions as SRO racks, except in stainless. Make use of where rust-resistance is required.
Floor Helical Racks (KRHG – KRHGF – KRHGFD) : Excellent items with high precision and power, and low noise and abrasion characteristics.
Metal Helical Racks (SRH – SRHF – SRHFD) : Effective in reducing noise and vibration due to larger contact ratio of helical gears.
Molded Versatile Racks (DR) : Used in applications because of its flexibility, where metallic racks do no possess this attribute. Pinions and accessories are also available.
Molded Versatile Rack Clamps (SRS) : Utilized to secure Molded Versatile Racks.
Molded Versatile Rack Pinions (SSDR) : Spur pinions utilized for molded flexible racks.
Flexible Rack Information Rails (ARL) : Guideline Rails for Molder Flexible Racks.
We offer as standard a wide range of Racks in Metric and Imperial sizes. Spur Racks can be found in Steel (En8) or more to 2 metres in length. Stainless Steel and Delrin (Plastic) Racks are created with Spur and Helical tooth forms, square and circular sections up to 400mm in length. Alternative materials are available on demand. Moulded Hostaform Racks are available to offer an economical alternative where less torque is required.
Variable stiffness can improve the capacity for human-robot interacting. Based on the mechanism of a flexible rack and gear, a rotational joint actuator called vsaFGR can be proposed to modify the joint stiffness. The flexible gear rack could be regarded as a mixture of a nonlinear elastic element and a linear adjusting mechanism, providing advantages of compactness. The joint stiffness is usually in the number of 217-3527 N.m/rad, in fact it is inversely proportional to the 4th-order of the apparatus displacement, and almost independent from the joint angular deflection, providing benefits of quick stiffness regulation in a brief displacement of 20 mm. The apparatus displacement with respect to the flexible gear rack is certainly perpendicular to the joint loading force, so the power necessary for stiffness regulating is really as low as 14.4 W, providing benefits of energy saving. The high compactness, great stiffness range and low power price of vsaFGR are proved by simulations and experiments.
