GEAR COUPLINGS P SERIES

Product catalog summary
Overview: The document provides technical specifications and guidelines for the P Series gear couplings, which are designed to handle maximum torque up to 381,000 Nm and bores up to 370 mm. The gear couplings feature crowned hub teeth for enhanced contact area and reduced surface stress, leading to a longer lifespan.
Specifications:
  • Maximum Torque: Up to 381,000 Nm
  • Bores: Up to 370 mm
  • Components: One-piece sleeve with internal straight teeth, hub teeth, calibrated special-steel screws, lubrication plugs, exposed bolt flange, identical hub diameters, machined bore and keyway upon request, steel forgings hubs and sleeves, O-Rings.
Selection Guidelines:
  1. Ensure the shaft outside diameter is less than or equal to the maximum bore inside diameter.
  2. Use the formula P x F x 9550Nm = n to check coupling capacity against job conditions, where P is power in kW, F is the service factor, and n is speed in RPM.
  3. Verify that the calculated torque does not exceed the nominal torque, especially during starts or short periods.
Service Factors: The document provides service factors for different types of loads and applications, ranging from uniform to very heavy shocks, with factors from 1.5 to 2.75.
Technical Data: The document includes detailed tables with dimensions, torque values, and other specifications for various types of gear couplings, including PST, PMM, PDMM, PFS, PSV, and PSE types.
Additional Products: The document also lists other Transfluid products such as fluid couplings, flexible couplings, air and hydraulic clutches, brakes, and power take-offs, with specifications for each.
Contact Information: Contact details for Transfluid offices in China, France, the UK, the USA, and the Netherlands are provided.

GEAR COUPLINGS P SERIES-2

1. One piece sleeve with internal straight teeth 3. Calibrated special-steel screws 4. Two lubrication plugs are mounted on each half sleeve 5. Flange supplied in exposed bolt version 7. Machined bore and keyway upon request 8. Steel forgings hubs and sleeves Hub teeth are designed with a special crowned form to ensure a contact area larger than the conventional crowning. This solution involves reduced surface stresses and consequently a longer working life of the coupling.

GEAR COUPLINGS P SERIES-3

HOW TO SELECT THE RIGHT COUPLING SIZE A. The selection depends on the shaft outside diameter that it has to be inferior or equal to the max. bore inside diameter accepted. B. Check the coupling capacity versus the actual job conditions, using the following formula F = Service factor according to tabulation hereunder 9550 = Fixed ratio n = Speed in Rev/min C. Verify that the figured reading does not exceed the nominal torque. Max torque can be transmitted by the coupling during starts or for short periods of time. • Maximum values referred to a speed range from 0 to 250 rpm. For higher speed see...
