Belts and rack and pinions possess a few common benefits for linear movement applications. They’re both well-established drive mechanisms in linear actuators, providing high-speed travel over extremely lengthy lengths. And both are frequently used in large Linear Gearrack gantry systems for materials handling, machining, welding and assembly, especially in the auto, machine tool, 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 has a big tooth width that provides high level of resistance against shear forces. On the powered end of the actuator (where the engine 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 is definitely often used for tensioning the belt, although some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied stress drive all determine the force that can be transmitted.
Rack and pinion systems found in linear actuators contain a rack (also referred to as the “linear gear”), a pinion (or “circular gear”), and a gearbox. The gearbox really helps to optimize the rate of the servo electric motor and the inertia match of the machine. The teeth of a rack and pinion drive can be directly or helical, although helical teeth are often used due to their higher load capability and quieter operation. For rack and pinion systems, the maximum force that can be transmitted is largely dependant on the tooth pitch and how big is the pinion.
Our unique knowledge extends from the coupling of linear program components – gearbox, electric motor, pinion and rack – to outstanding system solutions. We offer linear systems perfectly made to meet your specific application needs in conditions of the smooth running, positioning accuracy and feed force of linear drives.
In the research of the linear movement of the gear drive mechanism, the measuring system of the gear rack is designed to be able to gauge the linear error. using servo engine straight drives the gears on the rack. using servo motor directly drives the gear on the rack, and is dependant on the movement control PT point setting to realize the measurement of the Measuring range and standby control requirements etc. In the process of the linear movement of the gear and rack drive mechanism, the measuring data is certainly obtained by using the laser beam interferometer to measure the position of the actual movement of the gear axis. Using the least square method to solve the linear equations of contradiction, and also to extend it to a variety of occasions and arbitrary amount of fitting functions, using MATLAB programming to obtain the actual data curve corresponds with design data curve, and the linear positioning precision and repeatability of gear and rack. This technology could be prolonged to linear measurement and data analysis of the majority of linear motion system. It can also be used as the foundation for the automated compensation algorithm of linear motion control.
