Belts and rack and pinions possess several common benefits for linear motion applications. They’re both well-set up drive mechanisms in linear actuators, providing high-speed travel over extremely lengthy lengths. And both are frequently 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 typical tooth geometry for belts in linear actuators is the AT profile, which includes a huge tooth width that provides high level of resistance against shear forces. On the powered 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 assistance. The non-driven, or idler, pulley is certainly often used for tensioning the belt, although some designs provide tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied tension power 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 gear”), and a gearbox. The gearbox really helps to optimize the speed of the servo motor and the inertia match of the machine. One’s teeth of a rack and pinion drive can be Linear Gearrack directly or helical, although helical the teeth are often used because of their higher load capability and quieter operation. For rack and pinion systems, the maximum force that can be transmitted is definitely largely dependant on 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. We offer linear systems perfectly designed to meet your specific application needs when it comes to the soft 
running, positioning accuracy and feed drive of linear drives.
In the research of the linear movement of the apparatus drive mechanism, the measuring platform of the apparatus rack is designed in order to measure the linear error. using servo electric motor straight drives the gears on the rack. using servo motor directly drives the apparatus on the rack, and is based on the motion control PT point setting to recognize the measurement of the Measuring range and standby control requirements etc. In the process of the linear movement of the gear and rack drive system, the measuring data is usually obtained utilizing the laser interferometer to measure the position of the actual motion of the gear axis. Using minimal square method to resolve the linear equations of contradiction, and also to prolong it to a variety of times 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 could be prolonged to linear measurement and data evaluation of nearly all linear motion mechanism. It can also be utilized as the foundation for the automated compensation algorithm of linear movement control.
