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 lengthy lengths. And both are frequently used in large gantry systems for materials handling, machining, welding and assembly, specifically 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 typical tooth geometry for belts in linear actuators may be the AT profile, which includes a big tooth width that provides high level of resistance against shear forces. On the powered end of the actuator (where in fact the engine is 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 definitely often used for tensioning the belt, although some styles provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied tension drive all determine the pressure that can be transmitted.
Rack and pinion systems used in linear actuators consist of a rack (generally known as the “linear gear”), a pinion (or “circular equipment”), and a gearbox. The gearbox helps to optimize the quickness of the servo electric motor and the inertia match of the machine. The teeth of a rack and pinion drive could be directly or helical, although helical tooth are often used because of their higher load capability and quieter procedure. For rack and pinion systems, the utmost force that can be transmitted is largely dependant on the tooth pitch and how big is the pinion.
Our unique knowledge extends from the coupling of linear system components – gearbox, motor, pinion and rack – to outstanding system solutions. We offer linear systems perfectly designed to meet your specific application needs with regards to the soft running, positioning precision and feed pressure of linear drives.
In the study of the linear movement of the gear drive system, the measuring platform of the gear rack is designed in order to measure the linear error. using servo engine straight drives the gears on the rack. using servo motor directly drives the gear on the rack, and is based 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 gear and rack drive mechanism, the measuring data is obtained utilizing the laser beam 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 lengthen it to any number of moments and arbitrary amount of fitting features, using MATLAB development to obtain the actual data curve corresponds with design data curve, and the linear positioning accuracy and repeatability of equipment and rack. This technology could be prolonged to linear measurement and data analysis of nearly all linear motion system. It may also be used as the foundation for the automated compensation algorithm of linear movement control.
