BONFIGLIOLI TMP-105 2 25 15 19 40 70 90 Planetary Gearbox
The BONFIGLIOLI TMP-105 2 25 15 19 40 70 90 planetary gearbox is a two stage precision reducer configured with a 25:1 ratio. The TMP-105 designation identifies the gearbox size and series, while the numeric codes define the shaft, flange, mounting, and option details. The two stage configuration provides a 25 to 1 reduction with high efficiency and smooth operation. This gearbox is suitable for automation equipment, positioning systems, and industrial machinery that require high torque density and precise motion control.
Product Overview
Planetary gearboxes use multiple planet gears that rotate around a central sun gear inside a ring gear. Because the load is shared among several planet gears, planetary reducers can transmit high torque in a compact package. The TMP-105 size is a mid sized unit suitable for moderate to high torque requirements. The two stage design allows the gearbox to achieve a 25:1 ratio while maintaining high efficiency.
The model codes describe the specific build. The numeric values relate to shaft, flange, mounting, and option details. Because these codes define critical interfaces, the nameplate and dimensional drawing should be consulted for exact installation data. The compact design makes the gearbox suitable for integration into automated machinery and positioning systems.
Construction and Design
The TMP-105 housing is designed for high rigidity so that the gear mesh remains stable under load. The planet gears, sun gear, and ring gear are manufactured to precise tolerances to provide smooth rotation and low backlash characteristics. Bearings support the input and output shafts and the planet carrier. Lubrication is contained within the housing and distributed to the gears and bearings during operation.
The output interface identified by the model codes determines how the gearbox connects to the driven machine. The input interface is designed to accept a matching motor or drive component. The mounting options allow the gearbox to be installed in different orientations to suit the machine layout.
Performance Characteristics
The 25:1 ratio of the TMP-105 two stage gearbox provides a moderate to high speed reduction with strong torque multiplication. The output speed is calculated by dividing the input speed by twenty five. The torque capacity depends on the gearbox size, the number of stages, the duty cycle, and the service factor. Planetary gearboxes are known for high torsional rigidity, which supports accurate positioning.
Efficiency is generally high in planetary gearboxes because the load is distributed across multiple gear contacts. Smooth operation and low backlash characteristics help maintain positioning accuracy. Thermal capacity should be checked for continuous duty or high ambient temperatures. The gearbox should be selected with an appropriate service factor.
Applications
The Bonfiglioli TMP-105 planetary gearbox is suitable for automated assembly systems, material handling equipment, packaging machinery, robotics, positioning tables, and general industrial drives. The 25:1 ratio is useful in applications that require moderate speed reduction and high torque output. The compact size allows the gearbox to fit into machine designs where space is limited.
The configuration codes adapt the gearbox to specific motor and mounting requirements. The gearbox can be paired with servo motors or standard motors depending on the application. When used in positioning systems, the torsional rigidity and low backlash characteristics help maintain accuracy.
Installation Guidelines
Installation should begin with a check of the nameplate data and the dimensional drawing. The gearbox should be mounted on a rigid base that can withstand the torque reaction. The input motor should be aligned with the gearbox input interface so that the shaft connection engages correctly. Couplings and shaft connections should be fitted according to the manufacturer recommendations.
The output shaft should be aligned with the driven equipment to avoid excessive radial and axial loads. Misalignment can cause premature bearing wear, vibration, and positioning error. After installation, the gearbox should be checked for smooth rotation and correct lubrication.
Maintenance Recommendations
Regular maintenance supports reliable performance and long service life. Lubrication should be checked and replenished according to the recommended schedule. The condition of the lubricant should be inspected for contamination or breakdown. Seals and bearings should be checked periodically. Leakage, abnormal noise, or vibration should be addressed promptly.
The exterior of the gearbox should be kept clean to support heat dissipation. Adequate airflow around the housing helps maintain stable temperatures. In dusty or humid environments, additional protection may be needed.
Selection Considerations
When selecting the TMP-105 2 25 gearbox, engineers should confirm the required output torque, output speed, duty cycle, and positioning accuracy. The 25:1 ratio and input speed determine the output speed. The available torque depends on the motor power and gearbox efficiency. A service factor should be applied for starting loads, shock loads, and continuous operation.
For positioning systems, backlash and torsional rigidity should be evaluated against the accuracy requirements. The input and output interfaces must match the motor and machine.
Conclusion
The BONFIGLIOLI TMP-105 2 25 15 19 40 70 90 planetary gearbox offers a compact two stage reduction solution with a 25:1 ratio and configurable interfaces. Its high torque density, torsional rigidity, and precise motion characteristics make it suitable for automation, positioning, and industrial machinery. With correct installation and maintenance, the gearbox provides reliable performance and long service life.
