Bonfiglioli W R 86 U 120 P80 B5 V5 Gearbox
Product Overview
The Bonfiglioli W R 86 U 120 P80 B5 V5 is an industrial right angle worm gearbox with code 2G30013944. It is intended for speed reduction and torque transmission in motor-driven machinery. The model reference identifies the gear size, ratio class, motor interface, and mounting arrangement. The right angle design supports compact machine layouts where the motor and driven shaft are not in line.
The gearbox 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. The unit should be installed by qualified personnel and according to technical documentation.
Construction and Mechanical Design
The worm gearbox 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. Seals retain lubricant and reduce the entry of dust and moisture.
Installation requires a clean and rigid mounting surface. The gearbox should seat without distortion. Fasteners must be tightened to the specified torque and checked after initial operation. Shaft connections should be aligned carefully. Excessive overhung load or belt tension can affect bearing life.
Motor Interface and Mounting
The P80 B5 V5 references define motor interface and mounting details. The motor flange, shaft, and pilot must match the gearbox input. Incorrect adaptation can cause vibration, misalignment, or damage. The motor should be fitted without force. Coupling and clamping elements should be tightened according to instructions.
The V5 mounting position affects lubrication and maintenance access. The installation should follow the specified orientation. The surrounding structure should provide access for lubrication checks and inspection.
Installation and Commissioning
Before installation, the gearbox 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. Fasteners should be tightened to the specified torque.
Commissioning should begin with a low load run where possible. Rotation direction, noise, vibration, leakage, and temperature should be checked. Fasteners should be rechecked after initial operation. 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. The mounting position determines the correct oil level and plug arrangement. Fill, level, and drain points should remain accessible.
Operating temperature should remain within the intended range. The housing should have adequate air flow. Excessive temperature can indicate overload, incorrect lubricant, or inadequate cooling.
Operation and Monitoring
During operation, the gearbox should run smoothly within the designed speed and torque range. Operators should monitor noise, vibration, temperature, and leakage. A change in running sound can indicate wear or lubrication problems.
Load changes can affect gearbox life. Increased throughput, higher torque, frequent reversing, 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. The gearbox should not be exposed to water, dust, or corrosive substances beyond its intended protection level.
Maintenance should include periodic inspection of lubricant, seals, fasteners, and housing condition. Before service, the machine must be isolated and secured against rotation.
Integration and Selection Summary
The W R 86 U 120 P80 B5 V5 gearbox can be integrated into industrial machines that require compact right angle speed reduction and torque transmission.
Selection should confirm the model W R 86 U 120 P80 B5 V5, code 2G30013944, ratio, motor interface, shaft arrangement, torque capacity, mounting position, and lubrication requirements.
