Bonfiglioli MP 130 1 4 STD 114A CD 35 S5 OR SB KE Planetary Gear Head

The Bonfiglioli MP 130 1 4 STD 114A CD 35 S5 OR SB KE Gear Head is a mechanical planetary reducer intended for compatible industrial drive systems. The MP 130 value identifies the frame size, the 1 4 values describe the stage and ratio reference, the STD designation indicates a standard configuration, the 114A value defines the motor interface, the CD value describes a configuration detail, and the 35 value describes the ratio. The S5 OR SB KE suffix describes further shaft and mounting options.

The MP series is associated with planetary gear heads 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 arrangement, the motor interface, the ratio, and several option details, and each value affects whether the unit fits the machine.

Reading the Reference in Order

The MP 130 value identifies the frame size and the approximate torque class. The 1 4 values describe the stage count and the ratio reference. The STD designation indicates a standard configuration. The 114A value defines the motor interface. The CD and 35 values describe configuration and ratio details, and the suffix describes shaft and mounting options.

Because each value carries meaning, the full string should be compared with the project drawing rather than with the frame size alone. Two units with the same frame size but different motor interfaces or different shaft references may not be interchangeable.

Mechanical Function

The gear head 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 ratio defined in the reference. The user should confirm the output speed, the output torque, and the permissible radial and axial loads against the machine requirement.

The gear head 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 gear head and for the connected shafts.

Motor Interface and Coupling

The 114A interface should be matched to the motor flange and shaft. Where a coupling is used between the motor and the gear head, 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. The gear head should be supported during fitting so that its weight does not load the motor bearing or the gear head bearing.

Mounting and Alignment

The gear head 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 gear head should not be distorted by uneven surfaces or excessive bolt force, because distortion can affect gear alignment and seal performance.

Shaft alignment to the driven machine should be checked carefully. Couplings should be aligned within the limits allowed by the coupling and gear head design. 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 gear head size, the mounting position, and the operating conditions. The user should follow the product documentation for lubricant selection and service intervals. Some precision gear heads are supplied with long life lubrication, and this should be confirmed from the documentation.

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 gear heads 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 gear head 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 gear head 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 ratio. The driven machine should be checked for smooth operation. Commissioning records should include the full reference, the ratio, the motor interface, and the test results.

Diagnostics and Maintenance

If the gear head runs noisily, the user should check alignment, mounting, lubrication, and load conditions. Vibration may come from the coupling, the driven machine, or the gear head itself, and the source should be identified before parts are replaced. If the gear head 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 130 gear head 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 130 1 4 STD 114A CD 35 S5 OR SB KE Gear Head is intended for compatible mechanical power transmission. Correct reference verification, mounting, alignment, lubrication, commissioning, and maintenance are essential.
