BONFIGLIOLI A302 UH35 P90 2D3D Stirnkegelradgetriebe Bevel Gearbox
The BONFIGLIOLI A302 UH35 P90 2D3D Stirnkegelradgetriebe is a right angle bevel gearbox configured with a P90 motor interface. The German term Stirnkegelradgetriebe refers to a bevel gear unit. The A302 designation identifies the reducer size and series, while the UH35 and 2D3D codes define the shaft, flange, and mounting details. This gearbox is suitable for conveyors, mixers, packaging equipment, and industrial machinery that require efficient right angle torque transmission.
Product Overview
Bevel gearboxes use bevel gears to transmit motion between shafts that intersect at an angle. The gear teeth are designed to engage smoothly and distribute load across the contact area. This construction provides high efficiency and reliable torque transmission in a compact right angle layout. The A302 size is a mid sized unit suitable for moderate to high torque requirements.
The P90 input flange allows a matching motor to be mounted to the gearbox. Direct mounting simplifies alignment and reduces the number of separate transmission components. The gearbox housing supports the shafts and bearings with high stiffness so that the gear mesh remains stable under load.
Construction and Design
The bevel gears are manufactured to precise tolerances to provide smooth rotation and efficient torque transfer. The housing supports the shafts and bearings with high stiffness. Bearings are selected for the radial and axial loads generated by the bevel gear action. Lubrication is contained within the housing and distributed to the gears and bearings during operation.
The P90 input flange is machined for precise motor mounting. The output shaft is machined to accept couplings, pulleys, sprockets, or other driven components. Correct alignment between the motor, gearbox, and driven equipment is important for efficient power transmission and long bearing life.
Performance Characteristics
The A302 bevel gearbox provides efficient right angle power transmission across a range of input speeds. Bevel gears generally offer higher efficiency than worm gears because the tooth contact involves less sliding. The reduction ratio of the unit determines the output speed and torque multiplication.
The gearbox should be selected with an appropriate service factor for the duty cycle. Starting loads, shock loads, and continuous operation affect the mechanical and thermal capacity of the unit. Lubrication condition and operating temperature should be monitored.
Applications
The Bonfiglioli A302 UH35 P90 bevel gearbox is suitable for belt conveyors, screw conveyors, mixers, agitators, packaging machines, and general industrial drives. The right angle layout is useful when the motor must be positioned at 90 degrees to the driven shaft. The efficient bevel gear design makes the unit suitable for continuous duty applications.
The P90 input flange supports direct motor mounting. The gearbox can be paired with standard three phase motors or other motors that match the interface. When variable speed operation is required, the motor and gearbox should be evaluated together.
Installation Guidelines
Installation should begin with a check of the nameplate data and a visual inspection of the gearbox. The unit should be mounted on a rigid base that can withstand the torque reaction. Mounting bolts should be tightened to the recommended torque. The motor should be aligned with the P90 flange so that the motor shaft engages the gearbox input correctly.
After installation, the gearbox should be checked for smooth rotation and correct oil level. A short run without load helps confirm that the assembly operates correctly. Any unusual noise, vibration, or temperature rise should be investigated before full service.
Maintenance Recommendations
Regular maintenance supports reliable performance and long service life. Oil level and oil condition should be checked at recommended intervals. The first oil change should be performed after the initial running in period, and later changes should follow the schedule for the operating conditions. Seals and bearings should be inspected periodically.
The exterior of the gearbox should be kept clean to support heat dissipation. Adequate airflow around the housing helps maintain stable temperatures. In dusty or humid environments, additional protection may be needed.
Selection Considerations
When selecting the A302 UH35 P90 2D3D gearbox, engineers should confirm the required output torque, output speed, duty cycle, and environmental conditions. The ratio and motor speed determine the output speed. The available torque depends on motor power and gearbox efficiency. A service factor should be applied for starting loads, shock loads, and continuous operation.
The P90 flange and mounting features must match the motor and machine. The output shaft and mounting features should match the driven equipment. For applications with high radial loads, additional bearing support may be required.
Conclusion
The BONFIGLIOLI A302 UH35 P90 2D3D Stirnkegelradgetriebe bevel gearbox offers a right angle reduction solution with efficient bevel gear transmission. Its construction supports reliable torque transfer and stable operation in conveyors, mixers, and industrial machinery. With correct installation and maintenance, the gearbox provides dependable performance and long service life.
