Belts and rack and pinions have got several common benefits for linear motion applications. They’re both well-founded drive mechanisms in linear actuators, offering high-speed travel over incredibly long lengths. And both are generally used in huge gantry systems for materials managing, machining, welding and assembly, specifically in the automotive, machine device, and packaging industries.
Timing belts for linear actuators are usually made of polyurethane reinforced with internal metal or Kevlar cords. The most common tooth geometry for belts in linear actuators may be the AT profile, which has a large tooth width that provides high resistance against shear forces. On the driven end of the actuator (where in fact the engine can be attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides assistance. The non-driven, or idler, pulley is usually often used for tensioning the belt, even though some styles offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied tension power all determine the drive which can be transmitted.
Rack and pinion systems found in linear actuators consist of a rack (also referred to as the “linear equipment”), a pinion (or “circular equipment”), and a gearbox. The gearbox really helps to optimize the acceleration 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 capacity and quieter operation. For rack and pinion systems, the utmost force which can be transmitted is usually largely dependant on the tooth pitch and the size of the pinion.
Our unique knowledge extends from the coupling of linear program components – gearbox, engine, pinion and rack – to outstanding system solutions. We offer linear systems perfectly made to meet your unique application needs in terms of the simple running, positioning precision and feed push of linear drives.
In the study of the linear motion of the gear drive system, the measuring platform of the gear rack is designed to be able to measure the linear error. using servo engine directly drives the gears on the rack. using servo motor directly drives the apparatus on the rack, and is dependant on the movement control PT point mode to recognize the measurement of the Measuring range and standby control requirements etc. In the process of the linear movement of the gear and rack drive mechanism, the measuring data is obtained by using the laser interferometer to gauge the position of the actual movement of the gear axis. Using the least square method to solve the linear equations of contradiction, and also to extend it to a variety of situations and arbitrary quantity of fitting functions, using MATLAB programming to obtain the real data curve corresponds with style data curve, and the linear positioning precision 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 used as the foundation for the automated compensation algorithm of linear movement control.
