Industrial Right Angle Gearbox
What are Industrial Right Angle Gearbox?
The HB series industrial right-angle gearbox, also known as the H/B series standard industrial gearbox, is a very common piece of equipment in the industrial transmission field. Its main function is to transmit power and reduce speed.
Simply put, the HB series includes two structural forms: the H series is a parallel shaft gearbox (input and output shafts are parallel), and the B series is a right-angle shaft gearbox (input and output shafts are at a 90-degree angle). This article focuses on the B series right-angle shaft gearbox.
The core advantage of the right-angle gearbox is that it allows the power transmission direction to turn by 90 degrees. In many places where installation space is limited or where power needs to bend, the right-angle gearbox proves invaluable.

High Transmission Efficiency
The HB series gearbox employs a precision gear design, resulting in high transmission efficiency and low energy consumption. Both helical and bevel gears undergo profile modification and grinding processes, along with hardening treatment, ensuring highly stable operation. Depending on the number of transmission stages, the average efficiency can reach 98% for a single stage, 96% for two stages, and 94% for three stages. Higher efficiency means greater energy savings.
Strong Load Capacity
The HB series right-angle gearbox boasts a wide torque range, with a maximum output torque of 3,450,000 N.m. Manufactured from high-strength materials, it is wear-resistant, impact-resistant, and has a long service life. This load capacity makes it suitable for various heavy-duty industrial applications.
Compact Structure and Flexible Installation
This gearbox features a modular design and a compact size, making it ideal for space-constrained installation environments. It supports multiple installation methods: horizontal installation, vertical installation, swing base installation, and torque arm installation. The output shaft also offers various options, including solid shafts, hollow shafts, hollow shafts with shrink discs, and splined shafts. This flexibility allows engineers to freely combine different configurations based on the actual equipment requirements.
