Flexible Gear Rack

Flexible plastic gear racks in 0.8 Mod (32DP) pitch. These racks can provide an easy to set up rotational drive as high as approx 270 degrees for example on camera focus rings. They also offer an economical answer where a big gear is necessary or a longer stretch (up to 2 metres) of linear motion is desired. These racks are compatible with our 0.8 Mod and 32 DP pitch Spur Gears.

We offer as standard an array of Racks in Metric and Imperial sizes. Spur Racks can be found in Steel (En8) and up to 2 metres long. STAINLESS and Delrin (Plastic-type material) Racks are created with Spur and Helical tooth forms, square and circular sections up to 400mm in length. Alternative materials are available on ask for. Moulded Hostaform Racks can be found to offer a cost-effective alternative where less torque is required.
Variable stiffness can improve the capability of human-robot interacting. Predicated on the system of a versatile rack and equipment, a rotational joint actuator named vsaFGR is usually proposed to regulate the joint stiffness. The versatile gear rack could be regarded as a mixture of a nonlinear elastic component and a linear adjusting mechanism, providing benefits of compactness. The joint stiffness is usually in the number of 217-3527 N.m/rad, and it is inversely proportional to the 4th-order of the gear displacement, and almost independent from the joint angular deflection, providing advantages of quick stiffness regulation in a short displacement of 20 mm. The apparatus displacement with respect to the flexible gear rack can be perpendicular to the joint loading power, so the power required for stiffness regulating is really as low as 14.4 W, providing advantages of energy saving. The high compactness, great stiffness range and low power price of vsaFGR are proved by simulations and experiments.
