Product catalog summary
General Information
This section provides an overview of the document, including measurement units, service factors, selection criteria, thermal power, and maintenance procedures. It highlights the importance of understanding the service factor (FS) for application qualification, considering load type, operation duration, and start frequency. The FS must be equal to or lower than the gear unit service factor Fs’.
Measurement Units
Defines units such as radial and axial loads in Newtons, dimensions in millimeters, and power in kilowatts. Conversion factors are provided for different units.
Service Factor
The service factor (FS) is crucial for determining application type, considering load nature, operation hours per day, and start-ups per hour. FS values differ based on motor type, with specific multipliers for internal combustion engines and self-braking electric motors.
Selection Process
Details the calculation of input power (P’) based on required torque (T2) and transmission ratio. It includes guidelines for selecting gearboxes and gearmotors, considering factors like input speed and service factor.
Verification and Overloads
Emphasizes checking radial and axial loads against admissible values. Allows for emergency overloads up to 100% of T2 torque during standard operation. Recommends torque limiting devices for frequent or higher overloads.
Thermal Power
Discusses rated thermal power (Pt0) for different gearbox types, indicating maximum admissible power under continuous duty at 30°C ambient temperature. Pt0 values should be corrected with coefficients to reflect actual operating conditions.
Specifications and Procedures
The document outlines the importance of adjusting the thermal power values (Pt0) using specific coefficients to account for real operating conditions. These coefficients include the temperature coefficient (ft), ventilation coefficient (fv), and utilization coefficient (fu). The document provides tables for these coefficients based on ambient temperature and operational minutes per hour.
Backstop Device Verification
After selecting the gearbox, it is crucial to verify that the maximum output torque (T2Mmax) provided by the backstop device is sufficient for the application's needs. This involves checking the torque (T2NOM) required to ensure motion irreversibility and considering load factors (fc) for different operational conditions.
Lubrication Guidelines
The document emphasizes the selection of appropriate lubricants based on operating and environmental conditions to ensure optimal gearbox performance. It discusses the importance of viscosity and additives in oils, recommending synthetic oils for their advantages in efficiency and stability.
Installation Recommendations
Proper installation is crucial to eliminate vibrations and ensure alignment between the gearbox, motor, and driven machine. The document advises using flexible couplings and installing protective devices like overload cutouts and torque limiters to prevent damage from prolonged overloads or shocks.
Key Tables and Data
- Table 3: Temperature coefficients (ft) based on ambient temperature.
- Table 4: Utilization coefficients (fu) based on operational minutes per hour.
- Table 5: Application factors (fa) based on insertions per hour and daily operating hours.
- Table 6: Temperature factors (ft) based on ambient temperature.
Additional Notes
If the gearbox operates below 0°C, special configurations with tight chambers are recommended to enhance the backstop device's performance. For further assistance, contact the technical department.
Specifications
The components to be fitted on the gear units must adhere to specific machining tolerances: SHAFT ISO h6 and HOLE ISO H7. This ensures proper alignment and functionality.
Installation Procedures
The gearbox should be mounted to eliminate vibrations, ensuring alignment with the motor and machine. Use elastic or self-aligning couplings where possible. If the gearbox is exposed to overloads, shocks, or blockage risks, install motor switches, torque limiters, or hydraulic couplings. Ensure radial and axial loads on drive and output shafts do not exceed permissible limits. Clean and lubricate surfaces before assembly to prevent seizure and oxidation. Use tie-rods and extractors for assembly, and protect oil seals during painting to maintain sealing properties. Verify lubricant levels and breather plug positions before operation, especially for outdoor installations.
Running-in Recommendations
Gradually increase transmitted power or limit the machine's resistant torque during the initial operating hours to ensure proper running-in of the gearbox.
Maintenance Guidelines
For gear units lubricated with mineral oil, change the oil after the first 500-1000 operating hours and flush the gearbox if possible. Regularly check lubricant levels and change oil every 4000 hours. If synthetic oil is used, oil changes can occur every 12500 hours. In humid environments, fill the gearbox with oil when inactive and restore the correct oil level before reuse.
Variator Operating Principle
The mechanical variator uses an epicyclic transmission for variable ratios. The motor rotates solar rings, which in turn rotate satellites. The position of the rolling contact point affects output speed and torque. Speed adjustments should only be made while the variator is running to avoid damage.
Variator Features
The UDL series variators are lightweight due to aluminum housing, allowing easy application and transport. They support both foot and flange mounting, reducing stock levels and delivery times. The closed input flange prevents oil leaks, and the magnetic breather plug extends maintenance intervals. The variators operate noiselessly and vibration-free in both directions.
Technical Data
The UDL series is available in sizes 002, 005, and 010, with specific power, speed, and torque specifications. Recommended lubricants include various ATF Dexron fluids from different brands.
Mounting Positions and Dimensions
Mounting positions include B5, V1, and V3, with specific dimensions provided for each UDL size. A breather plug kit is available for certain mounting positions.

I cuscinetti dell’albero veloce vengono sempre lubrificati con grasso a base sintetica; altri cuscinetti vengono lubrificati solo se la posizione di montaggio non ne garantisce la corretta lubrificazione. The bearings mounted on the input shaft are supplied with grease, synthetic base; the other bearings are lubricated only if the mounting position does not assure a correct lubrication. Una scelta oculata del tipo di lubrificante, in funzione delle condizioni operative e ambientali, consente ai riduttori di raggiungere le prestazioni ottimali. Le prestazioni dei riduttori indicate nelle tabelle...
