An Angular Gearbox is a specialized power transmission component designed to transfer torque and change the direction of rotation between non-parallel, intersecting shafts, typically at a 90-degree angle. Unlike inline gearboxes, these units are engineered to handle applications where space constraints or mechanical design necessitate a change in drive direction. They are integral to countless industries, from heavy-duty manufacturing and material handling to precision robotics and renewable energy systems. The core principle involves sets of bevel or miter gears that mesh at an angle, efficiently redirecting power flow with minimal energy loss and high reliability.
At Raydafon Group, we engineer our angular gearboxes to meet the most demanding operational challenges, combining robust construction with precision machining to deliver consistent performance and longevity.
The performance of an angular gearbox is defined by its precise technical parameters. Below are the standard specifications for Raydafon Group's core series.
| Model | Gear Ratio Range | Nominal Output Torque (Nm) | Input Speed Max (RPM) | Efficiency (%) | Backlash (arcmin) | Housing Material | Protection Class |
|---|---|---|---|---|---|---|---|
| AG-05 | 1:1 to 6:1 | 50 - 120 | 4000 | >96% | < 15 | Aluminum | IP54 |
| AG-10 | 1:1 to 10:1 | 130 - 400 | 3500 | >95% | < 15 | Cast Iron | IP55 |
| AG-20 | 1:1 to 15:1 | 450 - 1200 | 3000 | >94% | < 18 | Cast Iron | IP65 |
| AG-35 | 5:1 to 25:1 | 1300 - 3500 | 2500 | >93% | < 20 | Cast Iron (Reinforced) | IP65 |
Raydafon angular gearboxes are deployed across a diverse spectrum of sectors.
What is the primary difference between a spiral bevel and a hypoid angular gearbox?
Spiral bevel gears have intersecting shaft axes and offer high efficiency and load capacity with moderate ratios. Hypoid gears have offset, non-intersecting shafts. This design allows for larger gear diameters and higher gear ratios within a similar housing size, and often operates more quietly, but may have slightly lower mechanical efficiency due to increased sliding action.
How do I select the correct size of angular gearbox for my application?
Selection requires evaluating key parameters: Required output torque (including service factors for shock loads), input speed (RPM), desired gear ratio, duty cycle (continuous vs. intermittent), and the mounting environment. Raydafon Group provides detailed selection software and engineering support to ensure the chosen model meets your application's lifecycle and performance demands.
What maintenance does a Raydafon angular gearbox require?
Our standard units are designed for minimal maintenance. The primary task is periodic lubrication change. Initial oil change is recommended after the first 500-1000 operating hours, with subsequent changes typically every 4000-8000 hours, depending on operating temperature and load. Seals and bearings are generally maintenance-free for the life of the unit under normal conditions.
Can you provide custom shaft configurations or special flanges?
Yes, customization is a core strength at Raydafon Group. We regularly manufacture gearboxes with custom shaft diameters, lengths, keyways, splines, and specialized mounting flanges to directly interface with existing motors or driven equipment, reducing the need for additional couplings and adapters.
What does the protection class rating (e.g., IP65) mean for a gearbox?
The IP (Ingress Protection) rating indicates the level of protection against solids and liquids. For example, IP65 means the gearbox is "dust tight" (6) and protected against "low-pressure water jets from any direction" (5). This is crucial for applications exposed to dust, moisture, or washdown procedures, ensuring long-term reliability.
How critical is backlash, and what level should I choose?
Backlash is the slight gap between meshing gear teeth, allowing for lubrication and thermal expansion. Low backlash is critical in precision applications like robotics, indexing, and CNC machining to ensure positional accuracy and prevent "play." Standard industrial applications can often tolerate higher backlash. Raydafon offers ranges from precision (< 10 arcmin) to standard (< 20 arcmin) to suit different needs and cost points.
Are your angular gearboxes compatible with servo motors?
Absolutely. Many of our AG-Series models are specifically engineered for use with servo and stepper motors. They feature low inertia, high torsional stiffness, and optimized low-backlash gearing to maintain the high dynamic response and positioning accuracy required in servo-driven systems.
