Belts and rack and pinions possess 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 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 manufactured from polyurethane reinforced with internal steel or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which has a huge tooth width that delivers high level of resistance against shear forces. On the driven end of the actuator (where the motor is definitely 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 can be often used for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied stress power all determine the pressure which can be transmitted.
Rack and pinion systems used in linear actuators contain a rack (also referred to as the “linear equipment”), 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 can be directly or helical, although helical tooth 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 definitely largely dependant on 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. We offer linear systems perfectly made to meet your unique application needs when it comes to the simple running, positioning accuracy and feed push of linear drives.
In the study of the linear movement of the apparatus drive mechanism, the measuring platform of the gear rack is designed to be able to measure the linear error. using servo motor directly drives the gears on the rack. using servo engine directly drives the apparatus on the rack, and is based on the movement 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 is definitely obtained utilizing the laser beam interferometer to measure the placement of the Linear Gearrack actual movement of the gear axis. Using minimal square method to resolve the linear equations of contradiction, and to expand it to a variety of instances and arbitrary number of fitting functions, using MATLAB development 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 prolonged to linear measurement and data evaluation of nearly all linear motion system. It may also be used as the basis for the automated compensation algorithm of linear movement control.
