TAIXING
TAIXING K-Series 90 Degree Gearbox is a right-angle helical bevel speed reduction device exclusively developed for construction machinery and heavy-load working conditions. Adopting an innovative building-block modular design, it can be flexibly adapted to various power sources and construction machinery, with core functions of realizing 90-degree right-angle transmission, reducing speed and greatly increasing output torque. It perfectly solves the core pain points of limited installation space and heavy-load impact resistance of construction machinery, and is a cost-effective transmission solution for commercial buyers including engineering project contractors and machinery manufacturing plants.
Our 90 degree right angle gearbox for construction machinery adopts a 90-degree right-angle transmission structure, which greatly saves installation space, is perfectly suitable for equipment with limited installation space such as construction machinery and agricultural and forestry machinery, and can be flexibly installed in horizontal, vertical and other directions without additional modification of the equipment body, greatly reducing the equipment design and transformation costs.
Specially designed for the harsh working conditions of construction machinery such as heavy load, frequent start-stop and large impact load, the optimized spiral bevel gear meshing structure has ultra-high rigidity and impact resistance, can stably withstand instantaneous overload, and can maintain reliable power output even in harsh construction site conditions, effectively extending the service life of the equipment and reducing fault downtime.
The high precision helical bevel 90 degree speed reducer adopts grade 6 precision machining technology for gears, with stable transmission, small backlash and high control accuracy. At the same time, it greatly reduces the operating noise, meeting the noise and accuracy requirements of multiple scenarios such as construction machinery, food processing and wood processing.
The building-block modular design can flexibly match various mainstream motors, hydraulic motors and other power sources, support multi-model combination and connection, and can customize parameters such as speed ratio, shaft diameter and installation mode according to the needs of different construction machinery, with strong adaptability to meet diversified engineering application needs.

The 90 degree gearbox for construction machinery is the core transmission component for all kinds of engineering equipment, and is also widely used in:
Construction machinery (excavators, loaders, concrete mixing equipment, road construction machinery)
Food processing production lines
Wood processing machinery
Agricultural and forestry equipment
Bulk material conveyors
Crane and mineral processing machinery
TAIXING has advanced precision transmission equipment processing lines, with full-process process control for heavy-load working conditions. For box processing, we adopt full-process mold casting, artificial aging treatment, CNC machining center precision machining, and three-coordinate detector full-size inspection to ensure the box rigidity and installation accuracy, adapting to vibration and impact in harsh working conditions. For gear and gear shaft processing, we adopt precision forging, normalizing, carburizing and quenching (HRC58-62), precision gear grinding technology, with gear accuracy up to grade 6. Each 90 degree gearbox undergoes full-item testing such as load, noise and sealing before leaving the factory, ensuring 100% compliance with quality standards.
