Gearbox PG

此為帶輸出軸的低背隙行星式減速機，適合應用在高定位精度和高靈敏啟動的間歇式運轉。輸出端使用高品質的滾錐軸承，讓輸出軸可以承受更大的軸向和徑向負載。

Features

High positioning accuracy

Precision gear grinding results in smooth tooth surfaces and accurate tooth profiles.
The pinion and rack are fitted with a helical system and are hardened and precision ground.

High torque

High-quality tapered roller bearings enable the output shaft to withstand greater axial and radial loads, provide ultra-high torque, and have a wide range of applications.

High starting performance

The planetary structure offers excellent balance and high precision, along with low moment of inertia, and when combined with a servo motor, it provides excellent starting characteristics.

Low noise

The gears are precision ground, resulting in smooth tooth surfaces, high precision, smooth gear operation, and low noise.
It uses German-made premium synthetic lubricating oil, unlike the grease lubrication used in ordinary speed reducers. It has excellent fluidity, allowing the gears to operate under sufficient oil film protection, thus reducing noise.

Easy to install

The reducer connection plate and input shaft hole dimensions are designed flexibly to be compatible with servo motors from various brands.

Low tooth backlash

Precision machining and strict quality control:
The ultra-precision tooth backlash is 1 arc minute in one section and 3 arc minutes in two sections.
The precision tooth backlash is 2-3 arc minutes in one section and 4-5 arc minutes in two sections.
The standard tooth back clearance is 4-5 arc minutes in one section and 6-7 arc minutes in two sections.

Long lifespan, maintenance-free

Made of high-grade nickel-chromium-molybdenum alloy steel, the gears undergo deep carburizing and hardening treatment, followed by precision tooth surface grinding, resulting in high gear rigidity, smooth tooth surface, and excellent wear resistance, thus extending their service life.
It uses high-quality German-made synthetic lubricating oil with excellent fluidity and is rich in extreme pressure inhibitors, ensuring that all parts in the gearbox are fully lubricated and protected, eliminating the need for oil changes.
It uses a specially made high-quality, heat-resistant, wear-resistant and non-deteriorating oil seal, which ensures excellent sealing performance.
