Belts and rack and pinions possess a few common benefits for linear movement applications. They’re both well-established drive mechanisms in linear actuators, offering high-speed travel over extremely lengthy lengths. And both are generally used in huge gantry systems for materials handling, machining, welding and assembly, especially in the automotive, machine device, 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 is the AT profile, which includes a sizable tooth width that provides high level of resistance against shear forces. On the driven 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 flat pulley simply provides guidance. The non-driven, or idler, pulley is often utilized for tensioning the belt, although some styles provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure pressure all determine the power that can be transmitted.
Rack and pinion systems found in linear actuators contain a rack (also referred to as the “linear gear”), a pinion (or “circular equipment”), and a gearbox. The gearbox helps to optimize the velocity of the servo engine and the inertia match of the machine. The teeth of a rack and pinion drive can be straight or helical, although helical the teeth are often used due to their higher load capability and quieter operation. For rack and pinion systems, the maximum force that can be transmitted is usually largely determined by the tooth pitch and the size of the pinion.

We offer linear systems perfectly made to meet your unique application needs when it comes to the clean running, positioning precision and feed force of linear drives.
In the study of the linear motion of the gear drive system, the measuring system of the apparatus rack is designed in order to measure the linear error. using servo motor straight drives the gears on the rack. using servo motor directly drives the gear on the rack, and is dependant on the motion control PT point mode to recognize the measurement of the Measuring distance and standby control requirements etc. Along the way of the linear movement of the apparatus and rack drive system, the measuring data is definitely obtained by using the laser interferometer to measure the position of the actual movement of the apparatus axis. Using minimal square method to resolve the linear equations of contradiction, and also to extend it to any number of times and arbitrary amount of fitting features, using MATLAB development to obtain the real data curve corresponds with style data curve, and the linear positioning precision and repeatability of equipment and rack. This technology can be extended to linear measurement and data evaluation of the majority of linear motion mechanism. It may also be used as the basis for the automated compensation algorithm of linear motion control.
