Bonfiglioli W 86 U 40 P90 B5 B3 KV Gear Reducer

Product Overview

The Bonfiglioli W 86 U 40 P90 B5 B3 KV is an industrial worm gear reducer with a 40:1 ratio and a 35 mm bore. It is intended for speed reduction and torque transmission in motor-driven machinery. The model reference identifies the size, ratio, motor interface, and mounting arrangement.

The reducer is used in conveyors, packaging equipment, material handling, and general industrial machinery. Correct selection depends on output torque, input speed, duty cycle, mounting position, and environment.

Construction and Mechanical Design

The worm gear reducer contains a housing, worm shaft, worm wheel, bearings, and sealing elements. The worm and wheel arrangement provides speed reduction and torque increase in a compact layout. The housing supports the bearing arrangement and protects internal parts from contamination.

Installation requires a clean and rigid mounting surface. The reducer should seat without distortion. Fasteners must be tightened to the specified torque and checked after initial operation. The 35 mm bore must match the driven shaft.

Ratio and Motor Interface

The 40:1 ratio defines the relationship between input speed and output speed. The designer should confirm that the output speed and torque match the driven machine. Starting torque, peak torque, and shock loads should be considered.

The P90 B5 B3 references define motor interface and mounting details. The motor flange, shaft, and pilot must match the reducer input.

Installation and Commissioning

Before installation, the reducer should be inspected for damage and the identification details checked. The shaft and mounting surfaces should be clean. Alignment with the motor and driven machine should be verified.

Commissioning should begin with a low load run where possible. Rotation direction, noise, vibration, leakage, and temperature should be checked. The lubricant level should be confirmed according to the mounting position.

Lubrication and Thermal Conditions

Lubrication reduces friction and wear and helps remove heat from the gear mesh and bearings. The specified lubricant type and quantity must be used. Fill, level, and drain points should remain accessible.

Operating temperature should remain within the intended range. Excessive temperature can indicate overload, incorrect lubricant, or inadequate cooling.

Operation and Monitoring

During operation, the reducer should run smoothly within the designed speed and torque range. Operators should monitor noise, vibration, temperature, and leakage.

Load changes can affect reducer life. Increased throughput, higher torque, or shock loading should be reviewed against the original selection.

Protection and Maintenance

Reliability depends on correct mounting, suitable lubrication, and protection from contamination. Seals should be inspected for damage.

Maintenance should include periodic inspection of lubricant, seals, fasteners, and housing condition. Before service, the machine must be isolated and secured.

Integration and Selection Summary

The W 86 U 40 P90 B5 B3 KV reducer can be integrated into industrial machines that require compact worm gear speed reduction and torque transmission.

Selection should confirm the model W 86 U 40 P90 B5 B3 KV, 40:1 ratio, 35 mm bore, motor interface, torque capacity, and mounting position.
