Bonfiglioli MP 080 2 20 STD 73A1 CD Getriebe 12.7 S1 VB SB KE Planetary Gearbox

The Bonfiglioli MP 080 2 20 STD 73A1 CD Getriebe 12.7 S1 VB SB KE Planetary Gearbox is a mechanical reducer intended for compatible industrial drive systems. It is identified by the MP 080 frame size, the 2 20 stage and ratio reference, the STD designation, the 73A1 motor interface, the CD configuration reference, and the 12.7 ratio, followed by the S1 VB SB KE suffix. The German term Getriebe is used in technical documentation to describe a gearbox.

The MP series is associated with planetary gearboxes used where compact construction, good torque density, and controlled motion transmission are required. The reference string is long because it describes the frame, the stage configuration, the motor interface, the ratio, and several option details.

Reading the Reference in Order

The MP 080 value identifies the frame size and the approximate torque class. The 2 20 values describe the stage count and the ratio reference. The STD designation indicates a standard configuration. The 73A1 value defines an IEC 73 motor interface with an A1 flange arrangement. The CD value describes a configuration detail, and the 12.7 value describes the ratio. The suffix values describe shaft and mounting options.

Each of these values affects whether the gearbox fits the machine. Two units with the same frame size but different motor interfaces or different shaft references may not be interchangeable.

Mechanical Function

The gearbox transfers torque between the input and output shafts through its planetary stages. It reduces the input speed and increases the output torque according to the 12.7 ratio. The user should confirm the output speed, the output torque, and the permissible radial and axial loads against the machine requirement.

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

Motor Interface and Coupling

The 73A1 interface should be matched to the motor flange and shaft. Where a coupling is used between the motor and the gearbox, the coupling should be aligned within the limits allowed by the design. Where the motor shaft engages directly with a clamping hub, the fit and the clamping torque should be checked before assembly.

Impact on the shafts during assembly should be avoided, and the gearbox should be supported so that its weight does not load the motor bearing.

Mounting and Alignment

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

Shaft alignment to the driven machine should be checked carefully. Couplings should be aligned within the limits allowed by the coupling and gearbox design, and guards should be fitted where rotating parts are accessible.

Lubrication and Sealing

Lubrication is essential for reliable gear operation. The correct lubricant type and quantity depend on the gearbox size, the mounting position, and the 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.

Thermal Behaviour

Planetary gearboxes generate heat at the gear mesh, and the thermal capacity depends on the housing surface, the mounting position, and the ambient conditions. Good airflow around the housing supports stable operation. Where the gearbox is mounted inside an enclosure, the internal temperature should be considered in the design.

Commissioning

Commissioning should begin with a mechanical inspection. The mounting bolts, the couplings, and the guards should be checked, and 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, and the output speed should be checked against the expected value for the 12.7 ratio. The driven machine should be checked for smooth operation.

Diagnostics and Maintenance

If the gearbox runs noisily, the user should check alignment, mounting, lubrication, and load conditions. If it overheats, the load, duty cycle, ambient temperature, and lubrication should be reviewed.

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.

Application Value

The MP 080 planetary gearbox supports speed reduction and torque transmission in compatible machinery. It can be applied in positioning, conveyor, packaging, and other industrial drive arrangements where a compact planetary solution fits the design.

Summary

The Bonfiglioli MP 080 2 20 STD 73A1 CD Getriebe 12.7 S1 VB SB KE Planetary Gearbox is intended for compatible mechanical power transmission. Correct reference verification, mounting, alignment, lubrication, commissioning, and maintenance are essential.
