ZPTK High Rigidity Planetary Gearbox

Reinforced Transmission Architecture

The ZPTK High Rigidity Planetary Gearbox is designed for demanding motion control equipment. Its reinforced construction supports substantial radial and axial loads. The series includes ZPTK070, ZPTK090, ZPTK110, and ZPTK140 frame sizes. Different frame options simplify integration with various machine platforms. Multi-stage planetary transmission covers reduction ratios from 1 to 350. Rated output torque reaches 170 N·m on the largest configuration. Emergency stop torque reaches twice the rated output torque. This performance suits equipment with frequent starts, stops, and load changes.

Designed for Servo Motion Systems

The ZPTK High Rigidity Planetary Gearbox for Servo Motor suits dynamic servo transmission applications. Multiple motor interfaces simplify compatibility with different servo motors. The ZPTK070 supports maximum input speeds up to 4000 rpm. Larger frames provide stable output performance under demanding loads. The gearbox suits robotic axes, CNC machinery, and automated positioning systems. Its rigid structure helps limit transmission movement caused by changing loads. This design supports consistent mechanical positioning in repetitive operations.

Built for High-Load Automation

The ZPTK High Stiffness Planetary Gearbox targets industrial machinery requiring strong mechanical rigidity. Maximum radial force reaches 2700 N on the largest model. Maximum axial force reaches 1350 N. The series supports single-stage, two-stage, and three-stage configurations. Single-stage efficiency reaches up to 97%. Multi-stage configurations provide efficiency of approximately 95%. These combinations balance torque, speed, and reduction requirements. Typical applications include robotic arms, rotary tables, automation platforms, and heavy-duty positioning systems.

Precision Manufacturing and Long-Term Operation

The ZPTK series uses a precision planetary transmission architecture. Gear teeth, bearings, and critical interfaces require controlled machining accuracy. Assembly procedures maintain consistent component alignment and mechanical fit. Finished units can undergo transmission performance and operational inspections. Synthetic grease provides continuous lubrication for internal transmission components. The IP65 rating helps protect internal components from dust and water exposure. Average service life reaches 20,000 hours. The ZPTK Precision Planetary Gearbox for Industrial Automation suits demanding continuous-duty equipment.

Flexible Machine Integration

The ZPTK series offers multiple motor input and output interface configurations. Different mounting options accommodate diverse motors and mechanical structures. Product weight ranges approximately from 4.2 to 28.0 kg. The mechanical architecture suits equipment requiring rigidity and substantial load capacity. Engineers can select the appropriate frame according to torque and reduction requirements. The series serves robotics, CNC machinery, automated production lines, and precision motion platforms. It provides a stable reduction solution for demanding industrial transmission systems.
