SUNUS TECH CO., LTD.

Gearbox UM

極佳剛性，使用大型高品質滾錐軸承，能承受更大的軸向和徑向的負荷。

加大盤面設計,使輸出軸能夠承受超大的輸出扭力，專為重負荷、高精密、耐久性的機械而設計製造的減速機。

Features

Super torque

Large, high-quality tapered roller bearings can withstand greater axial and radial loads, and the enlarged disc design allows the output shaft to withstand extremely high output torque and has excellent rigidity, making it suitable for heavy machinery with high torque.

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 high start-up performance.

High positioning accuracy

Precision gear grinding results in smooth tooth surfaces and accurate tooth profiles.
The gearbox and inner ring gear adopt an integral structural design and are made of special alloy steel, which has high stability.

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.

The output is easy to integrate.

The output shaft is available in standard, hollow, and slotted types for customers to choose from. Custom assembly methods specified by customers can also be accepted.

Low tooth backlash

Precision machining and strict quality control:
The standard tooth back clearance is 2-3 arc minutes for a single segment; 3-4 arc minutes for a double segment; and 4-7 arc minutes for a triple segment.
Precision tooth backlash is 1-2 arc minutes in a single segment; 2-3 arc minutes in a double segment; and 2-4 arc minutes in a triple segment.
Lower back clearance is also acceptable.

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.
