In the field of precision mechanical processing, the positioner is a key auxiliary device for achieving multi-face workpiece machining and improving processing efficiency. Its tilting accuracy, load-bearing capacity, and operational stability directly determine the machining accuracy of workpieces and the continuous operation efficiency of production lines. As the core transmission component of positioners, the spur gear slew drive precisely meets the stringent requirements of machine tool machining by virtue of its core advantages of high transmission accuracy, strong heavy-load adaptability, and high reliability, serving as a key support for enabling efficient production in precision machining.
The spur gear slew drive adopts a high-precision tooth profile design and precision gear grinding technology to reduce gear meshing backlash, ensuring positioning accuracy at any angle and satisfying the stringent requirements for workpiece angular positioning in precision machining. Whether it is multi-station switching for complex curved surface machining or precise alignment of symmetrical components, it can achieve stable and reliable power transmission and positioning.
In semiconductor packaging and testing lines, the die insertion machine is a key device that enables precise alignment between chips and carriers. Its operational accuracy and speed directly determine the yield rate of chip packaging and the efficiency of the production line.
In scenarios such as workshop material handling and equipment maintenance, the stable operation of jib cranes is directly related to lifting safety and operational efficiency — and the key to supporting the precise and reliable rotation of their boom is the spur gear slew drive system integrated into the base.
The spur gear slew drive adopts a precision tooth profile design combined with a gear grinding process, with the transmission backlash controlled within 0.02 mm. When integrated with the steering mechanism of the drive wheel, it enables the AGV to achieve a steering accuracy of ±0.5° — even in narrow passages, the AGV can travel precisely along the preset path, avoiding frame collisions and path deviations.
Small-module Tooth Profile DesignThe spur gear slew drive adopts an optimized small-module tooth profile design. Compared with traditional large-module gears, small-module gears feature smaller tooth pitches and a greater number of teeth, enabling tighter meshing during transmission and minimizing transmission backlash to an extremely narrow range.
This spur gear slew drive is manufactured from high-strength alloy materials, with its core components—the raceway and gear teeth—both treated with a professional quenching process. After quenching and strengthening, the hardness and wear resistance of the raceway are significantly enhanced. Even under the harsh working condition of high overturning load, it can still maintain excellent operational stability, providing a solid guarantee for the safety and reliability of lifting operations.
