علبة التروس الخطية

They run quieter compared to the straight, specifically at high speeds
They have a higher contact ratio (the number of effective teeth engaged) than straight, which escalates the load carrying capacity
Their lengths are fine round numbers, e.g. 500.0 mm and 1,000.0 mm, for easy integration with machine bed lengths; Straight racks lengths are usually a multiple of pi., electronic.g. 502.65 mm and 1005.31 mm.
A rack and pinion is a kind of linear actuator that comprises a set of gears which convert rotational movement into linear movement. This mixture of Rack gears and Spur gears are usually known as “Rack and Pinion”. Rack and pinion combinations are often used within a straightforward linear actuator, where in fact the rotation of a shaft driven yourself or by a engine is converted to linear motion.
For customer's that want a more accurate motion than ordinary rack and pinion combinations can't provide, our Anti-backlash spur gears can be found to be utilized as pinion gears with our Rack Gears.

The rack product range consists of metric pitches from module 1.0 to 16.0, with linear force capacities as high as 92,000 lb. Rack styles include helical, directly (spur), integrated and round. Rack lengths up to 3.00 meters can be found regular, with unlimited travels lengths possible by mounting segments end-to-end.
Helical versus Straight: The helical style provides many key benefits over the directly style, including:

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 has a sizable tooth width that delivers high level of resistance against shear forces. On the powered end of the actuator (where in fact the electric موتور 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 usually often used for tensioning the belt, even though some styles offer tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied tension pressure all determine the pressure which can be transmitted.
Rack and pinion systems found in linear actuators contain a rack (generally known as the “linear equipment”), a pinion (or “circular equipment”), and a علبة التروس. The gearbox really helps to optimize the swiftness of the servo engine and the inertia match of the machine. The teeth of a rack and pinion drive can be directly or helical, although helical the teeth are often used due to their higher load capability and quieter operation. For rack and pinion systems, the utmost force that can be transmitted is definitely largely dependant on the tooth pitch and how big is the pinion.
Our unique understanding extends from the coupling of linear program components – gearbox, electric motor, pinion and rack – to outstanding system solutions. You can expect linear systems perfectly designed to meet your unique application needs with regards to the smooth running, positioning accuracy and feed pressure of linear drives.
In the study of the linear movement of the apparatus drive mechanism, the measuring platform of the apparatus rack is designed to be able to measure the linear error. using servo motor straight drives the gears on the rack. using servo electric motor directly drives the والعتاد on the rack, and is based on the motion control PT point Linear Gearrack setting to recognize the measurement of the Measuring range and standby control requirements etc. Along the way of the linear movement of the apparatus and rack drive system, the measuring data can be obtained by using the laser beam interferometer to gauge the placement of the actual motion of the apparatus axis. Using minimal square method to solve the linear equations of contradiction, and also to lengthen it to any number of situations and arbitrary quantity of fitting functions, using MATLAB development to obtain the real data curve corresponds with style data curve, and the linear positioning accuracy and repeatability of equipment and rack. This technology could be prolonged to linear measurement and data evaluation of the majority of linear motion mechanism. It can also be used as the basis for the automatic compensation algorithm of linear motion control.
Comprising both helical & straight (spur) tooth versions, within an assortment of sizes, components and quality amounts, to meet almost any axis drive requirements.
