Industrial Reducer Helical Bevel Gear 90 Angle Spiral Bevel Gear

Industrial Reducer Helical Bevel Gear 90 Angle Spiral Bevel Gear
The 90 angle gear of the micro reducer is a "transmission artifact" in space-constrained scenarios. Its 90° vertical transmission, miniaturized design and efficient deceleration capabilities make it a core component in the fields of high-end manufacturing and precision instruments.

Working Principle and Core Functions of Micro Reducer 90 Angle Gears

The core function of gears is to "decelerate and increase torque"—through gear meshing, they convert high-speed, low-torque input power into low-speed, high-torque output power. The 90-degree rotation design also solves the problem of transmission direction conversion within spatial constraints (for example, converting horizontal rotation to vertical, or vice versa). The details are as follows:

1. The input shaft rotates the driving pinion, whose teeth push the teeth of the driven gear. Because the two shafts are perpendicular, a 90° deflection is achieved during power transmission.

2. Because the driven gear has a larger diameter than the driving gear, the transmission ratio is greater than 1, resulting in a reduced speed and amplified torque.

Typical Applications of Micro Reducer 90 Angle Gears

Robotics and Automation:

Used for precise angular adjustment in the shoulder and elbow joints of collaborative robots, and for vertical material transfer in semiconductor wafer handling equipment.

Medical Devices:

The steering mechanisms of surgical robot arms (such as the wrist gear in the da Vinci surgical system) and drill bit drives in dental implant machines require an extremely small size and high transmission accuracy.

Consumer Electronics and Precision Instruments:

The focus motors of camera lenses, the pan/pitch rotation of drone gimbals, and the stepper motor reduction in smartwatches all rely on 90° gears to achieve compact layouts.

Aerospace:

The attitude control systems of small satellites and the steering mechanisms of Mars rovers require miniaturized, highly reliable 90° gear sets due to weight and space constraints.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears. In 2023, Hunan Dinghan New Material Technology Co., Ltd. was established as a specialized international export business department. CSG has strong scientific research and development capabilities and is also equipped a full set of advanced equipment including seven-axis five-linkage CNC spiral bevel gear grinding machines and gear milling machines. By making the best use of the scientific and technological achievements and equipment of the Gear Research Institute of Central South University, machanical processing, heat treatment and testing.
