Belts and rack and pinions have a few common benefits for linear motion 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 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 typical tooth geometry for belts in linear actuators may be the AT profile, which has a huge tooth width that provides high level of resistance against shear forces. On the powered end of the actuator (where the motor is attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides guidance. The non-driven, or idler, pulley can be often used for tensioning the belt, even though some styles offer tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied stress pressure all determine the power which can be transmitted.
Rack and pinion systems found 
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 acceleration of the servo electric motor and the inertia match of the machine. One’s teeth of a rack and pinion drive can be straight or helical, although helical tooth are often used due to their higher load capacity and quieter operation. For rack and pinion systems, the maximum force that can be transmitted can be 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 made to meet your specific application needs in conditions of the soft running, positioning accuracy and feed pressure of linear drives.
In the study of the linear motion of the gear drive system, the measuring system of the gear rack is designed in order to measure the linear error. using servo electric motor directly drives the gears on the rack. using servo electric motor directly drives the apparatus on the rack, and is based on the motion control PT point mode to realize the measurement of the Measuring distance and standby control requirements etc. Along the way of the linear motion of the gear and rack drive mechanism, the measuring data can be obtained utilizing the laser interferometer to measure the placement of the actual motion of the apparatus axis. Using minimal square method to solve the linear equations of contradiction, and also to prolong it to a variety of situations and arbitrary quantity of fitting functions, using MATLAB development to obtain the real data curve corresponds with design data curve, and the linear positioning precision 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 utilized as the basis for the automatic compensation algorithm of linear motion control.
