BONFIGLIOLI W 86 U 30 P100 B5 B3 Cambio Riduttore

The BONFIGLIOLI W 86 U 30 P100 B5 B3 cambio riduttore is a W86 worm gear reducer configured with a P100 B5 motor flange and B3 mounting. The Italian terms cambio riduttore refer to a gear reducer. The W86 size is designed for robust industrial duty and is suitable for conveyors, mixers, and general machinery. The right angle layout allows the motor to be positioned at 90 degrees to the driven shaft, which can save space in machine frames.

Product Overview

The W series uses a worm and wheel design to achieve high reduction ratios in a single stage. A hardened and ground worm shaft drives a bronze worm wheel, producing smooth motion and low noise. The W86 size offers high torque capacity in a compact housing. The U30 code defines the shaft, ratio, and mounting details of the unit. The P100 B5 motor flange and B3 mounting make the gearbox suitable for a wide range of industrial installations.

The gearbox housing is designed for rigidity so that the gear mesh remains stable under load. Bearings support the radial and axial forces generated by the worm gear action. Seals protect the lubricant and bearings from dust and moisture. Lubrication is contained within the housing and distributed to the gear mesh and bearings during operation.

Construction and Design

The worm shaft is hardened and ground for smooth contact and reduced wear. The bronze worm wheel provides favorable friction characteristics and contributes to quiet operation. The housing maintains correct alignment between the worm and wheel under load. The P100 B5 interface is machined for precise motor mounting. The B3 foot mounting includes holes for securing the unit to a machine frame or baseplate.

The output shaft is machined to accept couplings, pulleys, sprockets, or other driven components. The housing design supports heat dissipation, which is important in worm gearboxes because sliding contact generates heat. Proper lubrication and clean exterior surfaces help maintain stable operating temperatures.

Performance Characteristics

The W86 gearbox provides smooth and quiet power transmission across a range of input speeds. The sliding contact between the worm and wheel produces gradual torque transfer, which helps reduce shock in driven equipment. The reduction ratio of the unit determines the output speed and torque multiplication. The P100 B5 motor flange allows the gearbox to be paired with a matching motor for a compact drive package.

Worm gearboxes have a self locking tendency under many load conditions. This can be useful when the load must remain in position after the motor stops. However, self locking is not guaranteed in all conditions and should be verified for the specific application. Efficiency depends on the ratio, load, speed, and lubrication.

Applications

The Bonfiglioli W 86 U 30 P100 B5 B3 reducer is suitable for belt conveyors, screw conveyors, mixers, agitators, packaging machines, and general industrial drives. The robust W86 size is useful in applications that require higher torque capacity and reliable operation. The right angle layout allows the motor to be positioned at 90 degrees to the driven shaft, which can save space in machine frames.

The P100 B5 flange supports direct motor mounting, which simplifies alignment and reduces the number of separate transmission components. The B3 foot mounting provides a stable installation on baseplates and frames. The gearbox can be paired with standard three phase motors or other motors that match the interface.

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. The B3 mounting bolts should be tightened to the recommended torque. The motor should be aligned with the P100 B5 flange so that the motor shaft engages the gearbox input correctly.

The output shaft should be aligned with the driven equipment to avoid excessive loads on bearings and seals. 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.

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 W 86 U 30 P100 B5 B3 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 P100 B5 flange and B3 mounting must match the motor and machine. The output shaft and mounting features should match the driven equipment. For applications that rely on holding or self locking, the load conditions should be evaluated carefully.

Conclusion

The BONFIGLIOLI W 86 U 30 P100 B5 B3 cambio riduttore offers a robust reduction solution with a P100 B5 motor flange and B3 mounting. Its cast iron construction and worm gear design support smooth torque transmission and reliable performance in conveyors, mixers, and industrial machinery. With correct installation and maintenance, the gearbox provides dependable operation and long service life.
