Bonfiglioli A 30 2 UH35 13.6 P90 B3 Gearbox

The Bonfiglioli A 30 2 UH35 13.6 P90 B3 Gearbox is a mechanical reducer intended for compatible industrial drive systems. It is identified by the model A 30 2 UH35 13.6 P90 B3 and the reference 1229170386. The gearbox transmits power from a motor to a machine while providing speed reduction and torque multiplication.

A gearbox is part of a mechanical power train. Its performance depends on correct selection, mounting, shaft alignment, lubrication, and load matching. The A 30 unit should be integrated with attention to the motor interface, output shaft connection, mounting position, and environmental conditions.

Role in Mechanical Power Transmission

The A 30 gearbox transmits torque between the input and output shafts through its gear stage. It reduces motor speed and increases output torque according to the gear ratio. The model reference includes a 13.6 ratio indication. The exact mechanical characteristics should be confirmed against the product documentation.

The gearbox should not be exposed to loads beyond its specified capacity. Shock loads, misalignment, and excessive overhung loads can affect bearings and seals. The machine design should provide adequate support for the gearbox and connected shafts.

Model Identification and Compatibility

The model A 30 2 UH35 13.6 P90 B3 and the reference 1229170386 should be checked against the project requirements. The complete identification includes mechanical details that must match the application. Similar gearboxes can differ in ratio, shaft arrangement, flange, and mounting position.

Compatibility includes the motor interface, input shaft, output shaft, mounting holes, and available space. The user should confirm that the motor and gearbox connect correctly. If the gearbox is part of an existing machine, the original mounting position and coupling arrangement should be reviewed.

Mechanical Installation

The gearbox should be mounted on a rigid structure that can support the torque and load. The mounting surface should be clean and flat. Fasteners should be tightened to the specified values. The gearbox should not be distorted by uneven mounting surfaces or excessive bolt force.

Shaft alignment should be checked carefully. Couplings should be aligned within the limits allowed by the coupling and gearbox design. Belt, chain, or gear connections should follow the machine design and the product documentation.

Lubrication and Sealing

Lubrication is essential for reliable gear operation. The correct lubricant type and quantity depend on the gearbox size, mounting position, and operating conditions. The user should follow the product documentation for lubricant selection and service intervals.

Seals protect the lubricant and exclude contamination. During inspection, the user should check for leakage around shafts and joints. Oil stains may indicate seal wear or loose connections. The breather and fill points should be kept clean.

Thermal and Environmental Considerations

The gearbox should be installed in an environment that matches its protection and cooling requirements. Ambient temperature, ventilation, and heat from nearby equipment affect operating temperature. The gearbox should not be covered by materials that prevent heat dissipation.

If the application includes high duty cycles or high ambient temperature, the thermal capacity should be reviewed. Good airflow around the housing supports stable operation. In harsh environments, additional protection may be required.

Commissioning

Commissioning should begin with a mechanical inspection. Mounting bolts, couplings, and guards should be checked. The lubricant level should be confirmed. The gearbox should be run at low load where possible to observe noise, vibration, and leakage.

The direction of rotation should be confirmed. The driven machine should be checked for smooth operation. Commissioning records should include the model code, mounting position, lubricant information, and test results.

Diagnostics and Troubleshooting

If the gearbox runs noisily, the user should check alignment, mounting, lubrication, and load conditions. Vibration may come from the coupling, the driven machine, or the gearbox itself. The source should be identified before parts are replaced.

If the gearbox overheats, the user should review load, duty cycle, ambient temperature, and lubrication. A sudden temperature rise may indicate a lubrication problem or abnormal mechanical resistance.

Maintenance

Routine maintenance should include checking for leakage, noise, vibration, and loose fasteners. The lubricant should be inspected and changed according to the service plan. Maintenance work should be performed with the machine isolated and secured.

If the gearbox must be replaced, the replacement unit should match the mechanical interface and ratio. The coupling should be realigned after installation. Lubricant should be filled to the correct level for the mounting position.

Application Value

The A 30 2 UH35 13.6 P90 B3 gearbox supports speed reduction and torque transmission in compatible machinery. It can be applied in conveyor, mixing, packaging, and other industrial drive arrangements where the gearbox design fits the application.

Summary

The Bonfiglioli A 30 2 UH35 13.6 P90 B3 Gearbox is intended for compatible mechanical power transmission. Correct model verification, mounting, shaft alignment, lubrication, commissioning, and maintenance are essential.
