Belts and rack and pinions have several common benefits for linear motion applications. They’re both well-established drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. 
And both are generally used in large gantry systems for materials managing, machining, welding and assembly, especially in the automotive, machine tool, and packaging industries.
Timing belts for linear actuators are usually manufactured from polyurethane reinforced with internal steel or Kevlar cords. The most typical tooth geometry for belts in linear actuators may be the AT profile, which includes a large tooth width that provides high level of resistance against shear forces. On the powered end of the actuator (where the engine is definitely attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides assistance. The non-driven, or idler, pulley is definitely often used for tensioning the belt, even though some styles 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 consist of a rack (also referred to as the “linear gear”), a pinion (or “circular gear”), and a gearbox. The gearbox helps to optimize the velocity of the servo electric motor and the inertia match of the machine. One’s 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 operation. For rack and pinion systems, the maximum force which can be transmitted is certainly largely dependant on the tooth pitch and the size of the pinion.
Our unique knowledge 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 conditions of the even running, positioning accuracy and feed drive of linear drives.
In the study of the linear motion of the apparatus drive system, the measuring platform of the apparatus rack is designed in order to gauge the linear error. using servo electric motor directly drives the gears on the rack. using servo electric motor directly drives the gear on the rack, and is based on the motion linear gearrack china 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 gear and rack drive system, the measuring data is obtained by using the laser beam interferometer to measure the placement of the actual movement of the gear axis. Using minimal square method to resolve the linear equations of contradiction, and to expand it to a variety of situations and arbitrary amount 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 gear and rack. This technology can be extended to linear measurement and data evaluation of the majority of linear motion mechanism. It can also be used as the foundation for the automatic compensation algorithm of linear movement control.
Consisting of both helical & straight (spur) tooth versions, within an assortment of sizes, materials and quality levels, to meet nearly every axis drive requirements.
These drives are ideal for a wide variety of applications, including axis drives requiring exact positioning & repeatability, journeying gantries & columns, pick & place robots, CNC routers and materials handling systems. Weighty load capacities and duty cycles may also be easily taken care of with these drives. Industries served include Materials Managing, Automation, Automotive, Aerospace, Machine Tool and Robotics.
