Load Factors (F L )

0.8 1 1.25

Moderate Shock Load

Heavy Shock Load 1.5 1.75 2

Calculate the power capacity required for the

gearbox:-P (kW) = gearbox:-Pd (kW) x FL Where Pd = Power required to drive the machine

FL = Load factor (refer to table)

Select a gearbox type to the closest above the required power (Pd), refer 4.3.2.2

Find the closest matching output speed hence gear ratio for that gearbox type for the application (refer 4.3.2.2.)

Check that the gearbox power rating is suitable for the actual output speed

4.3 REDUCTION GEARBOXES

M - Most / All gear ratios available

R - Reduced range of gear ratios available

F - Few gear ratios available

For exact availability of gear ratios in power ranges and full gearbox details consult Power Jacks

F l exi bl e Coup l ings

Coupling Torque, T (Nm) =

Selection of Coupling Type

The selection of coupling type depends on the installation and the type of misalignment The

three main types of misalignment encountered

are:-1. Angular Misalignment is usually present to some extent on all applications, typical values

1° - 2° Sometimes higher values are necessary

2. Parallel (Radial) Misalignment is also nearly always present A well aligned installation might

have values below 0.25 mm

3. Axial Misalignment (End Float) sometimes caused by thermal expansion or as a result of

machine design

Other considerations

include:-• Backlash Free Couplings are either one part couplings or have bolted joints These are

effective for precise positioning and to avoid wear on reversing drives

• Torsional rigidity of couplings depends on the joining method Types with rubber or plastic

elements can be considered as torsionally soft and will have a amount of twist at rated torque

Procedure:-1. Decide if the coupling should be torsionally soft or rigid

2. Consider whether a small amount of backlash is acceptable

3. Calculate the required coupling torque

4. Make a provisional selection

5. Check that the coupling’s maximum speed is sufficient

6. Check that the coupling’s dimensions are acceptable

7. Contact Power Jacks with your order or technical enquiry

Selection of Coupling Size

where S = Service Factor - dependant on drive conditions (refer to each coupling)

Select the coupling which is rated above the calculated torque If a brake is present in the system the coupling should be based on either the brake torque or the transmitted torque whichever is greater

General Notes

1. Maximum misalignment values are extremes and should not be combined As operating misalignment approaches the maximum, torque and power ratings should be reduced to maintain life

2. Gear couplings accommodate parallel misalignment by converting it to angular misalignment at the gear meshes in the flexible halves of the coupling

3. The maximum axial misalignment values apply when the coupling is aligned If axial misalignment greater than the listed maximum is required, consult Power Jacks

4. The inertia values includes shafts through the bores

5. When ordering please quote the coupling size and type, specify the bore and keyway sizes, and advise if puller holes or set-screws are required

6. For maximum performance, the actuators, shafts, gear boxes and motor should be carefully aligned

7. Imperial couplings on request

Notes:- 1. All dimensions in millimetres

2. Dimension J is the clearance required to align the coupling when installing

3. These couplings are designed for grease lubrication A list of suggested lubricants and quantities is detailed in the installation manual supplied with each full coupling

4. Where a coupling is exposed to sustained temperatures above 120ºC (250ºF) a coupling with high temperature seals must be used, consult Power Jacks Ltd
