Belts and rack and pinions have a few common benefits for linear movement applications. They’re both well-founded drive mechanisms in linear actuators, offering high-speed travel over extremely lengthy lengths. And both are frequently used in large gantry systems for material handling, machining, welding and assembly, especially in the automotive, machine tool, and packaging industries.

Timing belts for linear actuators are usually made of polyurethane reinforced with internal steel or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which has a big tooth width that delivers high level of resistance against shear forces. On the driven end of the actuator (where the electric motor can be attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a flat pulley simply provides assistance. The non-powered, or idler, pulley is often used for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied tension pressure all determine the push that can be transmitted.
Rack and pinion systems found in linear actuators consist of a rack (generally known as the “linear equipment”), a pinion (or “circular gear”), and a gearbox. The gearbox helps to optimize the quickness of the servo engine and the inertia match of the machine. One’s teeth of a rack and pinion drive could be directly or helical, although helical tooth are often used due to their higher load capability and quieter operation. For rack and pinion systems, the maximum force that can be transmitted can be largely dependant on the tooth pitch and how big is the pinion.
Our unique understanding extends from the coupling of linear system components – gearbox, engine, pinion and rack – to outstanding system solutions. We offer linear systems perfectly made to meet your unique application needs with regards to the smooth running, positioning precision and feed power of linear drives.
In the study of the linear motion of the apparatus drive system, the measuring system of the gear rack is designed to be able to measure the linear error. using servo motor straight drives the gears on the rack. using servo engine directly drives the apparatus on the rack, and is based on the movement control PT point mode to understand the measurement of the Measuring range and standby control requirements etc. Along the way of the linear motion of the apparatus and rack drive mechanism, the measuring data is certainly obtained by using the laser interferometer to measure the position of the actual motion of the apparatus axis. Using the least square method to solve the linear equations of contradiction, and to expand it to a variety of times and arbitrary number of fitting features, using MATLAB programming to obtain the actual data curve corresponds with style data curve, and the linear positioning accuracy and repeatability of equipment and rack. This technology can be extended to linear measurement and data analysis of the majority of linear motion system. It may also be Linear Gearrack utilized as the basis for the automated compensation algorithm of linear movement control.
Consisting of both helical & straight (spur) tooth versions, in an assortment of sizes, components and quality levels, to meet nearly every axis drive requirements.

These drives are ideal for a wide variety of applications, including axis drives requiring exact positioning & repeatability, touring gantries & columns, pick & place robots, CNC routers and materials handling systems. Heavy load capacities and duty cycles can also be easily handled with these drives. Industries served include Materials Handling, Automation, Automotive, Aerospace, Machine Tool and Robotics.
