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), which must be equal to or lower than the gear unit service factor Fs’. This is calculated as the ratio between the rated torque (T2M) and the required torque (T2’).
Measurement Units
Standard measurement units are used, such as Newton (N) for loads, millimeters (mm) for dimensions, and kilowatts (kW) for power, with conversion factors provided.
Service Factor
The service factor (FS) is essential for determining application type, considering load nature, operation hours, and start-ups. FS values vary based on motor type, with specific multipliers for internal combustion engines and self-braking electric motors.
Selection Process
The selection process involves calculating input power (P’) based on required torque (T2) and determining the transmission ratio. The appropriate gearbox or gearmotor is selected based on these calculations, ensuring compatibility with motor size and power requirements.
Verification and Overloads
Verification involves checking radial and axial loads against admissible values. Overloads are permissible up to 100% of rated torque (T2) during standard operation. Frequent or higher overloads require torque limiting devices. Gear calculations comply with ISO standards, considering synthetic oil usage.
Thermal Power
Thermal power tables provide rated values (Pt0) for each gearbox type, indicating maximum admissible power under continuous duty at 30°C ambient temperature. Corrections are necessary for actual operating conditions, using specified coefficients to determine corrected thermal power (Ptc).
Specifications and Procedures
The document outlines specifications for operating gearboxes, focusing on thermal power correction and lubrication. It specifies that the initial thermal power value (Pt0) should be disregarded if operation is continuous for up to 1.5 hours followed by cooling periods. Corrected thermal power (Ptc) is calculated using temperature (ft), ventilation (fv), and utilization (fu) coefficients.
Temperature and Ventilation Coefficients
Temperature coefficient (ft) varies with ambient temperature, while ventilation coefficient (fv) depends on cooling method, ranging from forced cooling with a fan to natural cooling.
Backstop Device Verification
After selecting the gearbox, verify the maximum output torque (T2Mmax) provided by the backstop device under actual conditions. The torque must ensure motion irreversibility, with load factors (fc) adjusted for standard, moderate, or heavy shocks.
Application and Temperature Factors
Application factor (fa) is determined by the number of backstop device insertions per hour and daily operating hours. Temperature factor (ft) is based on ambient temperature during operation.
Lubrication
Bearing lubrication is crucial, with synthetic grease used for input shaft bearings. Lubricant selection should consider operating conditions to ensure optimal performance. Viscosity is key, with high viscosity recommended for low speeds/high temperatures and low viscosity for high speeds/low temperatures. Additives in mineral oils should be non-aggressive to seals.
Oil Base
Synthetic oils offer advantages such as lower friction, better stability, and adaptability to temperature changes, despite higher costs. Mineral oils are cost-effective and perform well during the running-in period.
Installation
Proper installation is essential to eliminate vibrations and ensure alignment between the gearbox, motor, and driven machine. Use flexible or self-adjusting couplings and avoid exceeding radial and axial load limits on shafts.
Specifications
Components fitted on gear units must adhere to machining tolerances of SHAFT ISO h6 and HOLE ISO H7. Gearboxes are available in seven sizes with two reduction stages, designed for industrial use at ambient temperatures between -20°C and +40°C, up to an altitude of 1000 meters.
Installation Procedures
Gearboxes should be mounted to eliminate vibrations, ensuring alignment with the motor and machine. Use elastic or self-aligning couplings where possible. Protective measures such as motor switches, torque limiters, and hydraulic couplings should be installed if the gearbox is exposed to overloads or blockages. Before assembly, clean and lubricate surfaces to prevent seizure and oxidation. Use tie-rods and extractors for assembly, and protect oil seals during painting.
Lubrication and Maintenance
Check lubricant levels regularly and ensure the correct viscosity for the load type. For mineral oil-lubricated gear units, change the oil after the first 500-1000 operating hours and every 4000 hours thereafter. If synthetic oil is used, change it after 12500 hours. In humid environments, fill the gearbox with oil when inactive and restore the correct level before use.
Running-in Recommendations
Gradually increase transmitted power or limit the machine's resistant torque during the initial operating hours.
Technical Data and Performance
Performance calculations are based on an input speed of 1400 min-1. Efficiency can be estimated by ignoring non-significant variations. Thermal power values are provided for different gearbox sizes based on input rotation speed. Angular backlash is measured by rotating the output shaft and applying minimal torque.
Dimensions and Accessories
Detailed dimensions and specifications for each gearbox size are provided, along with available accessories and spare parts lists.
Specifications
The document provides detailed specifications for various components of shaft-mounted gearboxes, including input and output shafts, tensioners, and backstop devices. It includes measurements for different models (63B to 180B) such as dimensions (A, B, D, Lmax, Lmin), and torque values (T2M).
Procedures
The document outlines procedures for mounting and dismounting gearboxes with hollow output shafts. It emphasizes the importance of specifying the desired mounting position when ordering and provides guidelines for lubrication, including the use of synthetic oil with a viscosity class of ISO 150 for gearboxes equipped with a backstop device.
Standards and Recommendations
Recommendations include ensuring that radial and axial loads do not exceed permissible values indicated in the tables. The document also advises contacting technical services if operating conditions differ from the standard (ambient temperature and input speed of 1400 min-1).
Key Data from Tables
The tables provide critical data such as dimensions and torque values for different gearbox models, radial and axial load limits for input shafts, and spare parts lists including bearings and oil seals for each model.
Backstop Device
The backstop device is available on request and ensures motion irreversibility by allowing rotation of the output shaft only in the specified direction. It is crucial for applications requiring static irreversibility.
Lubrication
Gearboxes require oil lubrication and are equipped with filler, level, and drain plugs. The document specifies approximate oil quantities for different mounting positions and advises using synthetic oil for gearboxes with a backstop device.
Radial and Axial Loads
Radial forces generated by chain pinions, wheels, or pulleys are calculated using a specific formula. The document stresses that these forces must not exceed the admissible values provided in the tables.

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...
