PERFORMANCE DATA (T SERIES)
types TL & TS, plain bearings – 1200 rpm max
– 200 rpm for sizes 60-100
B
more than 250
(Please note that the nomograms do not apply to joints
assembled as telescopic drive shafts)
using the nomogram
The nomogram charts the maximum dynamic moment for each size
of joint. The curves represent the limit of performance and must not
be exceeded, however momentarily, by peak impulse loads.
The product of speed of rotation x working angle is given for values
from 250–12000. The upper speed limit for this series is 1200 rpm and
this corresponds to a maximum working angle of 10° at this speed.
Working angles up to 45° are practicable provided the corresponding
speeds are held within the limits of the nomogram. A double joint working
at 90° is considered the equivalent of two singles working at 45°.
selection
1. Determine the driving torque of the application in Newton metres
(Nm) and the speed of rotation in revolutions per minute (rpm).
If converting from other units:
1 lbf ft = 1.36 Nm
1 kpm = 9.81 Nm
The relationship between driving torque, speed of rotation and
power transmitted is expressed by the formul:
torque (Nm) = 7120
× HP
or
9550
× kW
rpm
2. Find the product of rpm
× working angle (β) and select the
appropriate service factor (SF) from table A or B after identifying
the nature of the loading on the transmission.
‘Uniform’ loads – typically electric motors driving fans, centrifugal
pumps or conveyors under constant load conditions.
‘Intermittent’ loads – presses, shears, radial displacement pumps
or compressors, all driven by electric motors.
‘Severe Intermittent’ loads – typically rolling mills or crushers or
‘intermittent’ type loads driven by I.C. motors with less than 4 cylinders.
3. If table A is relevant, multiply Nm
× SF and select a joint with a
static torque figure in excess of this value.
If table B is relevant, apply the products of Nm
× SF and rpm ×β
to the nomogram and select the joint with the performance curve
immediately above the point of intersection.
type TR, needle roller bearings – 6000 rpm max
– 3000 rpm for sizes 40 and 50
using the nomogram
The nomogram charts the maximum dynamic moment for each size
of joint. The curves represent the limit of performance and must not
be exceeded, however momentarily, by peak impulse loads.
The product of speed of rotation
× working angle is given for values
from 200–40000. The upper speed limit for this series is 6000 rpm and
this corresponds to a maximum working angle of 6° 30’ at this speed.
Working angles up to 45° are practicable provided the
corresponding speeds are held within the limits of the nomogram.
A double joint working at 90° is considered the equivalent of two
singles working at 45°.
selection
1. Determine the driving torque of the application in Newton metres
(Nm) and the speed of rotation in revolutions per minute (rpm)
2. Find the product of rpm
× working angle (β) and check that the
result is within the limits of the nomogram.
3. Apply the values obtained in 1) and 2) to the nomogram and
select the joint with the performance curve immediately above
the point of intersection. Normal safety factors are built into the
nomogram which is based on tests conducted with joints
operating under arduous conditions.
