Belts and rack and pinions have several common benefits for linear movement applications. They’re both well-founded drive mechanisms in linear actuators, providing high-speed travel over incredibly long lengths. And both are frequently used in huge gantry systems for materials handling, machining, welding and assembly, specifically in the automotive, machine tool, and packaging industries.
Timing belts for linear actuators are usually manufactured from 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 level of 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 flat pulley simply provides assistance. The non-powered, or idler, pulley can be often utilized for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure force all determine the power which can be transmitted.
Rack and pinion systems used in linear actuators contain a rack (generally known as the “linear equipment”), a pinion (or “circular gear”), and a gearbox. The gearbox helps to optimize the acceleration of the servo motor and the inertia match of the system. One’s teeth of a rack and pinion drive can be directly or helical, although helical teeth are often used due to their higher load capacity and quieter operation. For rack and pinion systems, the utmost force that can be transmitted can be largely determined by the tooth pitch and how big is the pinion.
Our unique knowledge extends from the coupling of linear system components – gearbox, electric motor, pinion and rack – to outstanding system solutions. You can expect linear systems perfectly made to meet your specific application needs in terms of the easy running, positioning accuracy and feed pressure of linear drives.
In the study of the linear movement of the gear drive system, the measuring platform of the apparatus rack is designed in order to measure the linear error. using servo motor directly drives the gears on the rack. using servo engine directly drives the gear 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 gear and rack drive system, the measuring data is usually obtained by using the laser interferometer to gauge the position of the actual motion of the apparatus axis. Using the least square method to resolve the linear equations of contradiction, and to prolong it to any number of instances and arbitrary number of fitting functions, using MATLAB programming to obtain the actual data curve corresponds with design data curve, and the linear positioning Linear Gearrack precision and repeatability of gear and rack. This technology could be prolonged to linear measurement and data evaluation of the majority of linear motion mechanism. It can also be utilized as the foundation for the automated compensation algorithm of linear motion control.
Consisting of both helical & directly (spur) tooth versions, within an assortment of sizes, materials and quality amounts, to meet almost any axis drive requirements.
These drives are perfect for an array of applications, including axis drives requiring precise positioning & repeatability, traveling gantries & columns, pick & place robots, CNC routers and material handling systems. Large load capacities and duty cycles may also be easily handled with these drives. Industries served include Material Handling, Automation, Automotive, Aerospace, Machine Device and Robotics.
