Product catalog summary
General Information
TRAMEC has launched a new range of worm gearboxes, each series offering features like high modularity, reduced weight, and high-speed reductions.
Measurement Units
Standard units are used for parameters such as power, torque, and load.
Power and Torque
Defines maximum applicable power at input and recommended motor power, with calculations for necessary input power based on required torque. Details maximum transmissible torque at gearbox output and geared motor output.
Reduction Ratio
Describes the speed reduction ratio.
Service Factor
Considers operating conditions like load type, operation duration, and start-ups per hour, with FS values adjusted for different motor types.
Efficiency
Dynamic and static efficiency are defined, noting a 30% reduction during initial operating hours.
Specifications and Load Conditions
Emphasizes selecting appropriate bearing configurations to avoid issues, specifying that maximum axial and radial loads should not occur simultaneously. Provides formulas for calculating radial and axial loads.
Thermal Power
Guidelines for rated thermal power (Pt0) under continuous duty at a maximum ambient temperature of 30°C, ensuring oil temperature does not exceed 95°C. Pt0 should be adjusted using specific coefficients for actual operating conditions.
Selection of Gearbox and Gearmotor
Guidelines include consulting performance tables to find a unit with a ratio close to the calculated one and ensuring compatibility with motor size and additional loads.
Lubrication
All gearboxes, except types X130 and K130, are supplied with synthetic lubricant (PAG base, ISO VG 320). Discusses viscosity considerations and the advantages of synthetic oils.
Installation
Gearbox installation should prevent vibrations and ensure alignment with the motor and machine. Outdoor installations require a breather plug with a valve, except for certain sizes. Designed for industrial use at ambient temperatures between -20°C and +40°C.
Maintenance
Worm gearboxes, except types X130 and K130, are lubricated for life with synthetic oil SHELL OMALA S4 WE 320, requiring no special maintenance other than external cleaning.
Painting
Sizes 90, 110, and 130 have cast iron housings painted BLUE RAL 5010, while smaller sizes have sandblasted aluminum housings.

1.6 Rendimento Rd - E il rendimento dinamico, definito come rapporto tra la potenza in uscita P2 e quella in entrata P1. Dipende principal-mente dalla velocita di strisciamento, dal tipo di lubrificante e dall' angolo d'elica. I valori indicati nelle tabelle sono validi se si applica la corrispondente coppia in uscita. In fase di rodaggio, circa le prime 300 ore di funzionamento sotto carico, il valore deve essere considerato inferiore del 30% rispetto a quello indicato in ta-bella. Rs - E il rendimento statico che si ha al momento dell' avviamento del riduttore e varia in base al rapporto di...

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...
