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, offering high-speed travel over extremely long lengths. And both are generally used in huge 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 metal or Kevlar cords. The most common tooth geometry for belts in linear actuators may be the AT profile, which has a big tooth width that provides high resistance against shear forces. On the driven end of the actuator (where the electric 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-powered, or idler, pulley is usually often used for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied stress push all determine the push that 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 helps to optimize the rate of the servo motor and the inertia match of the machine. The teeth of a rack and pinion drive could be straight or helical, although helical tooth are often used because of their higher load capacity and quieter operation. For rack and pinion systems, the maximum force which can be transmitted is usually largely determined by the tooth pitch and the size of the pinion.
Our unique understanding extends from the coupling of linear program components – gearbox, electric motor, pinion and rack – to outstanding Linear Gearrack system solutions. We offer linear systems perfectly made to meet your unique application needs when it comes to the smooth running, positioning accuracy and feed push of linear drives.
In the study of the linear movement of the gear drive mechanism, the measuring platform of the apparatus rack is designed in order to measure the linear error. using servo electric motor directly drives the gears on the rack. using servo motor directly drives the apparatus on the rack, and is based on the movement control PT point setting to understand 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 usually obtained by using the laser beam interferometer to gauge the placement of the actual motion of the apparatus axis. Using the least square method to solve the linear equations of contradiction, and also to lengthen it to a variety of situations and arbitrary quantity of fitting features, using MATLAB development to obtain the actual data curve corresponds with design data curve, and the linear positioning precision and repeatability of gear and rack. This technology can be prolonged to linear measurement and data analysis of the majority of linear motion system. It can also be utilized as the basis for the automatic compensation algorithm of linear movement control.
Consisting of both helical & directly (spur) tooth versions, within an assortment of sizes, components and quality amounts, to meet almost any axis drive requirements.
