Direct Shaft Helical Gearboxes (HG-Helical)
Direct Shaft Gearboxes with ground gears provide a robust and efficient solution for applications requiring quiet operation, high efficiency, and long-lasting durability. Due to these advantages, this type of gearbox is a popular choice across various industries, including food processing, robotics, and material handling.
The HG Series – Direct Shaft – includes gearboxes and motor gearboxes that transmit motion via helical gears. The design aligns the gearbox output shaft with the motor shaft, forming an integrated motor-gearbox assembly with compact size and excellent installation capability.
The gears are made of alloy steel with standard numbers 1.7225 and 1.7131, and the shafts are made of 1.1191 (CK45) steel. All mating and contact surfaces—including bearing and seal seats, shaft and gear contact surfaces, gear profiles, and input and output shafts—are hardened and ground.
Moreover, attention to detail in gear design and manufacturing, optimization of gear forms, precise machining of cast components, and accurate placement of all parts result in high efficiency, very low noise levels, minimal heat and vibration, and long service life. This series of products significantly distinguishes Rahnama gearboxes from similar offerings.
