Belts and rack and pinions have several common benefits for linear movement applications. They’re both well-founded drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. And both are generally used in large gantry systems for materials handling, machining, welding and assembly, specifically in the auto, machine tool, and packaging industries.
Timing belts for linear actuators are typically manufactured from polyurethane reinforced with internal steel or Kevlar cords. The most typical tooth geometry for belts in linear actuators may be the AT profile, which has a big tooth width that delivers high resistance against shear forces. On the powered end of the actuator (where the engine is usually attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides assistance. The non-powered, or idler, pulley is certainly often used for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied stress power all determine the drive that can be transmitted.
Rack and Linear Gearrack pinion systems used in linear actuators contain a rack (also referred to as the “linear gear”), a pinion (or “circular gear”), and a gearbox. The gearbox really helps to optimize the swiftness of the servo electric motor and the inertia match of the machine. The teeth of a rack and pinion drive can be straight or helical, although helical teeth are often used because of their higher load capability and quieter operation. For rack and pinion systems, the utmost force which can be transmitted is 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. 
You can expect linear systems perfectly designed to meet your specific application needs in conditions of the easy running, positioning precision and feed pressure 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 electric motor directly drives the gears on the rack. using servo motor directly drives the gear on the rack, and is based on the movement control PT point setting to realize the measurement of the Measuring distance and standby control requirements etc. In the process of the linear movement of the apparatus and rack drive mechanism, the measuring data is usually obtained utilizing the laser interferometer to measure the placement of the actual movement of the apparatus axis. Using minimal square method to resolve the linear equations of contradiction, and also to prolong it to a variety of moments and arbitrary amount of fitting functions, using MATLAB development to obtain the real data curve corresponds with design data curve, and the linear positioning precision and repeatability of equipment and rack. This technology could be extended to linear measurement and data evaluation of the majority of linear motion mechanism. It may also be utilized as the basis for the automated compensation algorithm of linear movement control.
