Belts and rack and pinions possess a few common benefits for linear movement applications. They’re both well-founded drive mechanisms in linear actuators, offering high-speed travel over extremely lengthy lengths. And both are generally used in huge gantry systems for material managing, machining, welding and assembly, especially in the automotive, machine device, 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 is the AT profile, which includes a large tooth width that provides high level of resistance against shear forces. On the driven end of the actuator (where the engine is Linear Gearrack certainly attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides guidance. The non-powered, or idler, pulley can be 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 force all determine the pressure that can be transmitted.
Rack and pinion systems found in linear actuators consist of a rack (generally known as the “linear gear”), a pinion (or “circular equipment”), and a gearbox. The gearbox really helps to optimize the acceleration of the servo electric motor and the inertia match of the system. The teeth of a rack and pinion drive could be directly or helical, although helical the teeth are often used due to their higher load capacity and quieter procedure. For rack and pinion systems, the utmost force that can be transmitted is definitely largely dependant on the tooth pitch and the size of the pinion.
Our unique understanding extends from the coupling of linear system components – gearbox, engine, pinion and rack – to outstanding system solutions. We offer linear systems perfectly designed to meet your specific application needs in terms of the easy running, positioning accuracy and feed power of linear drives.
In the research of the linear motion of the apparatus drive mechanism, the measuring platform of the gear rack is designed to be able to measure the linear error. using servo electric motor straight 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 understand the measurement of the Measuring range and standby control requirements etc. In the process of the linear motion of the gear and rack drive mechanism, the measuring data can be obtained utilizing the laser interferometer to gauge the position of the actual motion of the gear axis. Using the least square method to resolve the linear equations of contradiction, and to lengthen it to any number of moments and arbitrary quantity of fitting functions, using MATLAB development to obtain the real data curve corresponds with design data curve, and the linear positioning precision and repeatability of gear and rack. This technology can be prolonged to linear measurement and data evaluation of nearly all linear motion mechanism. It may also be used as the foundation for the automatic compensation algorithm of linear movement control.
