Spherical bevel gears are high-end transmission components with a spherical tooth profile design. Their tooth surfaces are distributed in a spherical arc shape, enabling smooth power transmission at any angle between the two shafts. They are suitable for high-speed, heavy-load, and variable shaft angle scenarios. Their tooth profile is formed using spherical involute machining technology, resulting in a 50% increase in tooth contact area compared to ordinary bevel gears and a transmission efficiency exceeding 96%, making them suitable for stable transmission under complex working conditions.
Spherical bevel gears Detail
| Product Material | bevel gears are typically made of high-strength metals (such as 20CrMnTi, 304 stainless steel, and titanium alloys). |
| Product Process | Raw material forging → rough turning / fine turning → gear ring milling → heat treatment → tooth surface fine grinding → non-destructive testing → dimension calibration, 18+ quality control steps to ensure performance. |
| Surface Treatment | "Carburizing and quenching + grinding + phosphating / chrome plating" process, Ra≤0.8μm, 48 hours salt spray corrosion-free, and hard corrosion resistance. |
| Customizable Products | Gears / Sprockets / Worms / Shafts / Rack Bars / Bevel Gears, etc. |

FAQ:
Are there any limits on the customizable shaft angle range for spherical bevel gears? What parameters are required?
The standard customization range is 15°-120°, and can be expanded to 5°-150° for special applications. Parameters such as shaft diameter, center distance, rated torque, operating speed, and shaft angle variation range must be provided.
Compared to ordinary bevel gears, spherical bevel gears have a higher procurement cost. What are their cost-effectiveness advantages?
Although the initial procurement cost is 20%-30% higher, the service life is extended by 35%, maintenance frequency is reduced by 40%, and transmission efficiency is improved by 3%-5%, resulting in a reduction of approximately 25% in overall long-term operating costs.
Does the shaft alignment accuracy requirement for spherical bevel gears increase during installation?
Because the spherical tooth profile has a certain degree of angular compensation, the shaft alignment deviation can be allowed to be ±0.8° (compared to ±0.5° for ordinary bevel gears), providing a higher installation tolerance. However, the center distance deviation must be ≤0.1mm.
For bulk purchases of spherical bevel gears, is installation and commissioning guidance available?
Yes. Bulk orders (50 pieces or more) receive free installation and commissioning technical guidance, including on-site installation and calibration, customized lubrication solutions, and troubleshooting training to ensure proper gear operation.
