Belts and rack and pinions possess a few common benefits for linear motion applications. They’re both well-set up drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. And both are frequently used in large gantry systems for material handling, machining, welding and assembly, especially in the auto, machine tool, and packaging industries.
Timing belts for linear actuators are usually made of polyurethane reinforced with internal steel or Kevlar cords. The most typical tooth geometry for belts in linear actuators is the AT profile, which includes a big tooth width that provides high level of resistance against shear forces. On the driven 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 assistance. The non-powered, or idler, pulley is usually often utilized for tensioning the belt, even though some styles provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied stress pressure all determine the power which can be transmitted.
Rack and pinion systems used in linear actuators contain a rack (generally known as the “linear gear”), a pinion (or “circular equipment”), and a gearbox. The gearbox really helps to optimize the velocity of the servo engine and the inertia match of the machine. The teeth of a rack and pinion drive could be directly or helical, although helical teeth are often used because of their higher load capability and quieter operation. For rack and pinion systems, the utmost force that can be transmitted can be largely dependant on the tooth pitch and the size of the pinion.
Our unique understanding 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 unique application needs in terms of the soft 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 to be able to gauge the linear error. using servo engine directly drives the gears on the rack. using servo motor directly drives the apparatus on the rack, and is dependant on the movement control PT point setting to realize the measurement of the Measuring distance and standby control requirements etc. In the process of the linear motion of the gear and rack drive system, the measuring data is certainly obtained by using the laser beam interferometer to gauge the placement of the actual movement of the gear axis. Using the least square method to solve the linear equations of contradiction, and also to prolong it to a variety of instances and arbitrary number of fitting functions, 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 extended to linear measurement and data evaluation of nearly all linear motion mechanism. It may also be utilized as the basis for the automated Linear Gearrack compensation algorithm of linear motion control.
