Belts and rack and pinions have a few common benefits for linear movement applications. They’re both well-set up drive mechanisms in linear actuators, providing high-speed travel over incredibly long lengths. And both are generally used in large gantry systems for materials managing, machining, welding and assembly, especially in the auto, machine tool, and packaging industries.
Timing belts for linear actuators are typically 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 has a large tooth width that provides high level of resistance against shear forces. On the powered end of the actuator (where the motor 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-driven, or idler, pulley is usually often utilized for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure power all determine the power that can be transmitted.
Rack and pinion systems found in linear actuators contain a rack (generally known as the “linear equipment”), a pinion (or “circular gear”), and a gearbox. The gearbox really helps to Linear Gearrack optimize the rate of the servo engine and the inertia match of the machine. The teeth of a rack and pinion drive could be directly or helical, although helical teeth are often used because of their higher load capability and quieter operation. For rack and pinion systems, the maximum force which 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, engine, pinion and rack – to outstanding system solutions. We offer linear systems perfectly designed to meet your specific application needs in terms of the simple running, positioning accuracy and feed drive of linear drives.
In the research 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 motor straight drives the gears on the rack. using servo electric motor directly drives the gear on the rack, and is based on the motion control PT point setting to recognize the measurement of the Measuring range and standby control requirements etc. In the process of the linear motion of the gear and rack drive mechanism, the measuring data is definitely obtained utilizing the laser beam interferometer to measure the position of the actual movement of the gear axis. Using the least square method to resolve the linear equations of contradiction, and also to extend it to any number of situations and arbitrary amount 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 could be prolonged to linear measurement and data analysis of nearly all linear motion mechanism. It can also be utilized as the basis for the automatic compensation algorithm of linear motion control.
