Belts and rack and pinions possess a few common benefits for linear motion applications. They’re both well-established drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. And both are generally used in large gantry systems for materials managing, machining, welding and assembly, especially in the automotive, 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 is the AT profile, which has a big tooth width that provides high level of resistance against shear forces. On the driven end of the actuator (where the engine can be attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a flat pulley simply provides guidance. The non-powered, or idler, pulley is certainly often utilized for tensioning the belt, although some designs provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied tension drive all determine the force that can be transmitted.
Rack and pinion systems found in linear actuators consist of a rack (also referred to as the “linear gear”), a pinion (or “circular gear”), and a gearbox. The gearbox helps to optimize the speed of the servo engine and the inertia match of the system. One’s teeth of a rack and pinion drive could be straight or helical, although helical teeth are often used due to their higher load capacity and quieter operation. For rack and pinion systems, the maximum force which can be transmitted is usually largely determined by the tooth pitch and the size of the pinion.
Our unique knowledge extends from the coupling of linear program components – gearbox, electric motor, pinion and rack – to outstanding system solutions. You can expect linear systems perfectly designed to meet your unique application needs in terms of the even running, positioning accuracy and feed push of linear drives.
In the research of the linear motion of the gear drive mechanism, the measuring platform of the apparatus rack is designed to be able to gauge the linear error. using servo electric motor straight drives the gears on the rack. using servo electric motor directly drives the gear on the rack, and is based on the movement control PT point setting to recognize the measurement of the Measuring distance and standby control requirements etc. In the process of the linear movement of the apparatus and rack drive system, the measuring data can be obtained by using the laser interferometer to gauge the placement of the actual motion of the apparatus axis. Using the least square method to resolve the linear equations of contradiction, and to extend it to any number of situations and arbitrary quantity of fitting functions, 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 evaluation of nearly all linear motion mechanism. It may also be utilized as the basis for the automated compensation algorithm of linear movement control.
