Belts and rack and pinions have got 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 generally used in large gantry systems for materials 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 metal or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which has a sizable tooth width that provides high resistance against shear forces. On the powered end of the actuator (where the motor is certainly 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 used for tensioning the belt, even though some designs offer tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure drive all determine the pressure which 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 equipment”), and a gearbox. The gearbox helps to optimize the rate of the servo engine and the inertia match of the system. One’s teeth of a rack and pinion drive can be straight or helical, although helical tooth are often used due to their higher load capability and quieter operation. For rack and pinion systems, the utmost force that can be transmitted can be 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 system solutions. We offer linear systems perfectly designed to meet your specific application needs when it comes to the easy running, positioning accuracy and feed drive of linear drives.
In the research of the linear movement of the gear drive system, the measuring platform of the gear rack is designed in order to measure the linear error. using servo engine directly drives the gears on the rack. using servo electric motor directly drives the gear on the rack, and is based on the motion control PT point setting to understand the measurement of the Measuring distance and standby control requirements etc. In the process of the linear movement of the gear and rack drive mechanism, the measuring data is obtained utilizing the laser interferometer to gauge the placement of the actual movement of the apparatus axis. Using the least square method to resolve the linear equations of contradiction, and to expand it to any number of occasions and arbitrary number of fitting functions, using MATLAB programming to obtain the real data curve corresponds with design data curve, and the linear positioning precision and repeatability of equipment and rack. This technology could be extended to linear measurement and data analysis of the majority of linear motion system. It may also be utilized as the basis for the automatic compensation algorithm of linear movement control.
