SK+/SPK+ Quick Gear Selection
Cyclic operation S5
Number of cycles
£ 1000/Stunde
Duty cycle
< 60% and < 20 min.* |
1. Using servomotor characteristic data, determine
the maximum motor acceleation torque:
TMaxMotMot [NM]
2. Determine maximum acceleration toruqe at the
gearhead output: T2b [NM]
T2b = TMaxMot l i (ratio)
3. Compare the maximum acceleration torque just
calculated with the permissible acceleration
torque T2b [NM] for the selected gearhead from
Requirement: T2b £ T2B
If not, choose another gearhead. |
4. Verifiy that the clamping hub
diameter (table on page 26) is
OK for the selected servomotor.
5. Compare the motor shaft
length, LMot [mm], with the min.
and max. clamping hub depth in
the dimensional sketches. |
Continous operation S1
Duty of cycle
³ 60% or ³ 20 min.*
|
1. Calculated after checking for cyclical operation
S5.
2. Determine the motor nominal torque: T1Mot [NM
(in.lb)]
3. Determine the rated load torque at the
gearhead output:
T2n [NM] = T1Mot l i (ratio) |
4. Compare the calculated rated
load torque with the
permissible rated torque T2n
[NM] for the selected
gearhead.
Requirements: T2n £ T2N
If not, choose another gearhead.
5. Determnominal input speed
n1n in rpm and compare with
permissible nominal input
speed of the gearhead, n1N
Requirements: n1n £ n1N
6. Verify proper clamping hub
diameter and motor shaft length
as in steps 4 & 5 above (S5). |
