Power Tool Gear Right Angle Cross Axis Helical Bevel Pinion Gear

Spiral bevel gears are commonly used as cross-axis gears for transmitting rotational motion between non-parallel and intersecting shafts. They are specifically designed to handle such applications and offer several advantages in terms of power transmission, efficiency, and smooth operation. Here's how spiral bevel gears function as cross-axis gears for rotational motion:

• Non-Parallel Shaft Alignment: Spiral bevel gears are suitable for transmitting motion between shafts that are not parallel. The intersecting shafts intersect at a specific angle, and the spiral bevel gears are precisely designed to accommodate this non-parallel configuration.
• Intersecting Shaft Angle: The intersecting shaft angle, often referred to as the bevel angle, determines the orientation of the spiral bevel gears. It is the angle formed between the rotational axes of the intersecting shafts. Spiral bevel gears are manufactured with teeth cut at the same angle, allowing for smooth meshing and power transmission at this specific bevel angle.
• Tooth Geometry: Spiral bevel gears have curved teeth that are cut in a helical pattern around the gear's circumference. The curvature and helical pattern enable gradual tooth engagement and provide uniform load distribution across the gear's face width. This results in smoother operation, reduced noise, and increased load-carrying capacity.
• Power Transmission: When the spiral bevel gears rotate, the teeth on one gear mesh with the teeth on the other gear, enabling torque transmission between the intersecting shafts. The spiral bevel gear design ensures efficient power transfer even at non-parallel shaft angles, allowing for reliable transmission of rotational motion.
• Axial and Radial Load Handling: Spiral bevel gears are capable of handling both axial and radial loads. The gear design and tooth engagement ensure that the transmitted loads are distributed evenly across the gear teeth, minimizing wear and maximizing the gear's load-carrying capacity.
• Manufacturing Precision: The manufacturing process of spiral bevel gears involves high precision to ensure accurate tooth profiles and proper gear meshing. The gears are typically generated using specialized cutting methods, such as Gleason or Klingelnberg processes, to achieve the desired tooth geometry and ensure smooth operation.

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.
