Belts and rack and pinions possess several common benefits for linear motion applications. They’re both well-established drive mechanisms in linear actuators, offering high-speed travel over extremely lengthy lengths. And both are generally used in large gantry systems for material managing, machining, welding and assembly, especially in the automotive, machine device, and packaging industries.
Timing belts for linear actuators are typically manufactured from polyurethane reinforced with internal steel or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which has a large tooth width that provides high level of resistance against shear forces. On the driven end of the actuator (where in fact the engine is usually attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a flat pulley simply provides guidance. The non-driven, or idler, pulley is often used for tensioning the belt, even though some designs provide tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied stress push all determine the power which can be transmitted.
Rack and pinion systems used in linear actuators contain a rack (also referred to as the “linear equipment”), a pinion (or “circular gear”), and a gearbox. The gearbox helps to optimize the velocity of the servo motor and the inertia match of the system. The teeth of a rack and pinion drive can be directly or helical, although helical tooth are often used because of their higher load capability and quieter procedure. For rack and pinion systems, the utmost force that can be transmitted is usually largely dependant on the tooth pitch and how big is the pinion.
Our unique understanding extends from the coupling of linear system components – gearbox, motor, pinion and rack – to outstanding system solutions. You can expect linear systems perfectly made to meet your unique Linear Gearrack application needs when it comes to the smooth running, positioning accuracy and feed drive of linear drives.
In the study of the linear motion of the gear drive mechanism, the measuring system of the gear rack is designed in order to measure the linear error. using servo electric motor directly drives the gears on the rack. using servo motor directly drives the gear on the rack, and is based on the movement control PT point mode to recognize the measurement of the Measuring distance and standby control requirements etc. Along the way of the linear movement of the apparatus and rack drive mechanism, the measuring data can be obtained utilizing the laser interferometer to gauge the placement of the actual motion of the apparatus axis. Using the least square method to solve the linear equations of contradiction, and also to prolong it to any number of instances and arbitrary number of fitting functions, using MATLAB programming to obtain the actual data curve corresponds with style data curve, and the linear positioning precision and repeatability of equipment and rack. This technology can be prolonged to linear measurement and data evaluation of the majority of linear motion system. It can also be used as the basis for the automatic compensation algorithm of linear motion control.
Comprising both helical & straight (spur) tooth versions, in an assortment of sizes, materials and quality levels, to meet almost any axis drive requirements.
These drives are ideal for a wide range of applications, including axis drives requiring precise positioning & repeatability, touring gantries & columns, pick & place robots, CNC routers and materials handling systems. Heavy load capacities and duty cycles can also be easily managed with these drives. Industries served include Material Managing, Automation, Automotive, Aerospace, Machine Device and Robotics.
