Product catalog summary
General Information
This section provides an overview of the document, focusing on measurement units, service factors, and selection criteria for gearboxes. It highlights the importance of understanding load type, operation duration, and start-up frequency to determine the appropriate service factor (FS).

Measurement Units
Standard units such as Newton (N) for loads, millimeters (mm) for dimensions, and kilowatts (kW) for power are used.

Service Factor
The service factor (FS) is essential for assessing gearbox suitability. It considers load type, daily operation hours, and start-up frequency. FS must be equal to or lower than the gear unit's rated service factor (Fs'). Adjustments are needed for different motor types.

Selection Process
Gearbox selection involves calculating input power (P') based on required torque (T2) and selecting the appropriate service factor. Guidelines are provided for selecting gearboxes and gearmotors, considering input speed and motor size compatibility.

Verification and Overloads
Verification ensures radial and axial loads are within limits. Overloads up to 100% of rated torque (T2) are allowed, but frequent or higher overloads require torque limiting devices. Gear calculations comply with ISO standards.

Thermal Power
Tables provide rated thermal power (Pt0) values for different gearbox types, indicating maximum admissible power under continuous duty at 30°C. Corrections are necessary for actual conditions to determine corrected thermal power (Ptc).
Specifications and Procedures
Adjusting thermal power values (Pt0) using specific coefficients accounts for real operating conditions, resulting in corrected thermal power values (Ptc). Key coefficients include temperature (ft), ventilation (fv), and utilization (fu).

Backstop Device Verification
After selecting the gearbox, verify that the maximum output torque (T2Mmax) provided by the backstop device meets application needs. This involves checking equations and considering load factor (fc) and application factor (fa).

Lubrication Guidelines
Select appropriate lubricants based on conditions to ensure optimal performance. Discusses viscosity, additives, and oil base, providing guidelines for choosing correct viscosity.

Installation Recommendations
Proper installation is crucial to eliminate vibrations and ensure alignment. Use flexible couplings and install protective devices if subject to overloads or shocks. Do not exceed allowed radial and axial loads.
Specifications
Components must adhere to specific machining tolerances: SHAFT ISO h6 and HOLE ISO H7. Designed for use within -20°C to +40°C and up to 1000 meters altitude.

Installation Procedures
Ensure vibrations are eliminated and alignment is precise. Use elastic couplings and install protective devices if necessary. Clean and lubricate surfaces before assembly.

Lubrication and Maintenance
Ensure correct lubricant quantity and position of plugs. For outdoor installations, use a breather plug with a valve. Change oil after specified operating hours.

Running-in Recommendations
Gradually increase transmitted power during initial hours.

Technical Characteristics
Gearboxes available in five sizes with three output shaft types. Made of engineering cast iron, ensuring rigidity and easy positioning. High-quality bearings support high loads.

Performance Specifications
Performance calculations based on 1400 min-1 input speed. Efficiency estimated at R = 0.97. Angular backlash measured by rotating output shaft.

Verificare che i carichi radiali agenti sugli alberi rientrino nei valori ammissibili riportati nelle relative tabelle. Tali valori (FR2) si riferiscono a carichi che agiscono a metà sporgenza dell’albero, per cui se il punto di applicazione è diverso, è necessario effettuare il calcolo dei nuovi valori ammissibili alla distanza (y) desiderata. Check that the radial loads on the shafts fall within to the admissible values reported in the relative tables. Reported values (FR2 refer to loads which affect the shaft at the half-way point of its projection; if the point of application is different,...

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...
