Belt pulley diameter

• The belt pulley is mounted at the end of the output shaft of the motor or gearbox.

• The diameter can be calculated by the pitch and the number of teeth (in the case of a toothed

belt).

• Value can be entered directly or calculated using a diameter calculator.

Mass of carriage

• The mass is used in the calculation for the moment of inertia

• The mass of the payload is entered when the motion profile is created.

• As the mass of the drive train is not customer information, it can be separately entered in the

"Extended data".

• By means of the mass calculator, an alternative value can be calculated.

β Angle of tilt (gradient)

• The value can be entered in degrees or as a percentage.

Symbol Description

Blt

Transmission efficiency of the toothed belt in the maximum stationary operating point.

• Since the torque loss of a belt is not proportional to its load, i. e. it is not constant throughout

the entire operating range, however, often only one efficiency factor is known, it is assumed

that the value applies to maximum steady-state operation. The losses that can be calculated

for this, in the worst case occur as a constant torque loss, so that they are taken into consid-

eration in the DSD.

• The losses of the guide can be covered separately with the specific travelling resistance.

Symbol Description

Mass of the drive train

• Since the mass of the drive train is only determined by the dimensioning process, an iteration

may be required here.

• First you can enter an estimated value here.

• If you have selected a drive, you can enter the actual value and check the calculation again.

• The masses of the products can be gathered from the catalogues.

• The mass is used in the calculation for the moment of inertia
