Belts and rack and pinions have several common benefits for linear movement applications. They’re both well-established drive mechanisms in linear actuators, providing high-speed travel over extremely lengthy lengths. And both are generally used in large gantry systems for material managing, machining, welding and assembly, specifically in the auto, machine device, and packaging industries.
Timing belts for linear actuators are typically made of polyurethane reinforced with internal steel or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which includes a large tooth width that delivers high level of resistance against shear forces. On the powered end of the actuator (where the electric motor 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 usually often utilized for tensioning the belt, even though some styles provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure drive all determine the power that can be transmitted.
Rack and pinion systems used 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 speed of the servo motor and the inertia match of the system. The teeth of a rack and pinion drive can be directly or helical, although helical the teeth are often used because of their higher load capacity and quieter procedure. For rack and pinion systems, the utmost force which can be transmitted is largely determined by the tooth pitch and how big is 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 designed to meet your unique application needs when it comes to the easy running, positioning precision and feed pressure of linear drives.
In the research of the linear motion of the gear drive system, the measuring system of the gear rack is designed to be able to gauge the linear error. using servo motor straight drives the gears on the rack. using servo motor directly drives the apparatus on the rack, and is dependant on the motion control PT point mode to realize the measurement of the Measuring range and standby control requirements etc. In the process of the linear motion of the apparatus and rack drive mechanism, the measuring data can be obtained utilizing the laser beam interferometer to gauge the placement of the actual movement of the apparatus axis. Using minimal square method to resolve the linear equations of contradiction, and to prolong it to any number of moments and arbitrary number of fitting features, using MATLAB development to obtain the real data curve corresponds with style data curve, and the linear positioning accuracy and repeatability of gear and rack. This technology can be extended to linear measurement and data analysis of the majority of linear motion mechanism. It can also be utilized as the basis for the automated compensation algorithm of linear motion control.
