Product catalog summary
General Information
TRAMEC has introduced a new range of worm gearboxes, including Series X, K, H, and combined series KX - XX - KK. These series are characterized by high modularity, reduced weight, and high-speed reductions.
Specifications
  • Measurement Units: Standard units for torque, power, and speed are used.
  • Power: Maximum applicable power is defined for continuous duty with specific service factors.
  • Reduction Ratio: Defined as the speed reduction ratio.
  • Torque: Maximum transmissible torque is specified for uniform loads.
  • Service Factor (FS): Considers application type, operation duration, and start-ups per hour. FS must be equal to or lower than the gearbox's FS'.
  • Efficiency: Dynamic and static efficiencies are defined, with adjustments for initial operating hours.
Procedures
  • Selection: Based on torque and power requirements, considering service factors.
  • Installation and Maintenance: Guidelines for proper installation and regular maintenance to ensure optimal performance.
  • Lubrication: Importance of using appropriate lubricants for efficiency and longevity.
Load Classes and Applications
Different load classes (A, B, C) are defined based on the nature of the load and operation conditions, with examples of suitable applications for each class.
Key Tables and Data
Tables provide FS values for different load classes and operating conditions, as well as efficiency values for dynamic and static conditions.
Specifications and Parameters
The document discusses the importance of the Rs value in selecting the appropriate gearbox for applications with intermittent operation. It notes that the static efficiency during the run-in period is 30% lower than the table values.
Efficiency and Gearbox Selection
Once the required reduction ratio is established, it is advisable to choose a gearbox type that offers better dynamic efficiency for the same ratio.
Irreversibility
External brakes are recommended for applications where backward motion must be prevented. Worm gearboxes naturally exhibit irreversibility, which increases with the reduction ratio. Static irreversibility occurs when Rs < 0.45, while dynamic irreversibility is influenced by dynamic efficiency and load vibrations.
Backlash
Angular backlash is measured by blocking the input shaft and rotating the output shaft, applying torque necessary to create gear tooth contact, not exceeding 2% of the maximum torque.
Radial and Axial Loads
Radial loads (Fr1 and Fr2) and axial loads (Fa1 and Fa2) are generated by transmission devices on input and output shafts. Load values depend on the position along the shaft projection, with adjustments needed for different positions.
Reinforced Versions
Reinforced versions with tapered roller bearings are available for higher load capacities compared to standard versions with radial ball bearings. These values are calculated based on bearing lifespan, and axial loads should compress the output flange.
Specifications and Load Considerations
The document discusses the importance of selecting the appropriate bearing version to avoid structural issues. It emphasizes that axial loads must compress the output flange and that axial and radial loads should not reach their maximum values simultaneously. If both forces are present, they must be reduced according to the prevailing load type. For radial load prevalence, the axial load is calculated as 37% of the radial load. For axial load prevalence, the radial load is 40% of the axial load.
Tapered Roller Bearings
Versions with tapered roller bearings can be supplied upon request, allowing for higher loads compared to standard products with angular contact ball bearings. The values are calculated based on bearing life, necessitating the selection of the most suitable version to avoid problems.
Thermal Power
The document provides tables for rated thermal power (Pt0) for gearboxes, applicable at a maximum ambient temperature of 30°C to ensure oil temperature does not exceed 95°C. Pt0 values need correction with coefficients to reflect actual operating conditions, resulting in corrected thermal power (Ptc).
Selection of Gearbox and Gearmotor
Guidelines for selecting a gearbox or gearmotor are provided, including ensuring compatibility with motor size and checking additional loads on shafts. The power absorbed by the gearbox should not exceed the thermal power limit.
Lubrication
All gearboxes, except types X130 and K130, are supplied with synthetic lubricant. The document highlights the importance of selecting the right lubricant based on operating conditions to ensure optimal performance. Viscosity is a critical parameter, with high viscosity recommended for low speeds/high temperatures and low viscosity for high speeds/low temperatures. Additives in oils should be non-aggressive to seals, and synthetic oils offer advantages such as lower friction and better stability.
Specifications
The document provides detailed specifications for torque limiters, including dimensions and measurements for various models. Key parameters include diameter, length, and other critical dimensions necessary for installation and operation.
Procedures
While specific procedures are not outlined, the document implies the importance of selecting the correct size and type of torque limiter based on the provided specifications to ensure proper functionality.
Standards and Recommendations
The document includes a spare parts list, indicating standard bearings and oil seals used in the assembly of torque limiters. It highlights the availability of tapered roller bearings upon request, suggesting customization options based on specific needs.
Data Tables
The document contains several tables listing dimensions and specifications for different torque limiter models. These tables provide critical data such as diameter, length, and other measurements essential for selecting the appropriate component.
Key Information
- The document emphasizes the importance of precise measurements and compatibility of parts.
- It provides a comprehensive list of spare parts, including bearings and oil seals, with specific dimensions.
- Customization options are available for certain components, such as tapered roller bearings.
Conclusion
This technical document serves as a detailed guide for selecting and assembling torque limiters, providing essential specifications and spare parts information to ensure optimal performance and compatibility.

Nelle applicazioni dove è necessario evitare la trasmissione del moto retrogrado o sostenere il carico, in assenza di alimentazione elettrica, è consigliabile adottare freni esterni. Nei riduttori a vite senza fine emerge questa caratteristica naturale, denominata grado di irreversibilità, che cresce con l’aumentare del rapporto di riduzione in quanto strettamente legata al relativo rendimento. The use of external brakes is advised in case of applications where backwards motion must be hindered and the load must be held should the feed be cut off. Per ottenere alti gradi di irreversibilità occorre...
