drylin® T - System design, horizontal, 1 rail and 1 carriage

2nd Step:

Check whether the clearances of the aggressive forces lie within the permitted values (see Maximum permitted clearances).

Maximum permitted clearances:

Option: 1 rail, 1 carriage
sy + sz < 2 Lx - Y0
ay + az < 2 Lx - Y0
sy < 5 Zm
sz < 5 Zm

3rd Step:

Calculate the required driving power

3.1

Center of mass in x- and z-direction within the carriage(s)

3.2

Center of mass in z-direction outside the carriage(s)

3.3

Center of mass in x-direction outside the carriage(s)
In case the position of the center of mass cannot be classified:



4th Step:

Calculate the maximum bearing load

4.1

Maximum bearing load in y-direction

4.2

Maximum bearing load in z-direction
A = Point of origin


Variables in the calculation:

Fa: Driving power [N]
Fs: Mass force [N]
Fy, Fz: Bearing load in y- or z-direction [N]
sx, sy, sz: Clearance of the mass force
in x-, y- or z-direction 		[mm]
ay, az: Clearance of the driving power
in y- or z-direction 		[mm]
wx: Clearance of the carriage on a rail [mm]
LX: Constant based on the installation size [mm]
Zm: Constant based on the installation size [mm]
Y0: Constant based on the installation size [mm]
b: Clearance of the guide rails [mm]
µ: Coefficient of friction,
µ = 0 in static loads,
µ = 0.2 in dynamic loads 		 
ZW: Number of carriages per rail  


The constant values:

Order no. LX ZM Y0

K2 (sy+Y0)/Lx
K3 |az/Lx|
K4 |sx/Lx|
K5 sz/Lx
K6 |(sy+Y0)/Zm|
K7 |sz/Zm|

5th Step:

Check the maximum bearing load of the most strongly stressed bearing with the calculated load in Step No. 4.

Maximum permitted load:

6th Step:

Determination of the maximum permitted speed for the load in Step No. 4
Diagram for the determination of the maximum permitted speed for the determined bearing load.
X = centric bearing load [N]
Y = permitted mean velocity [m/s]
