Mejorar el rendimiento de la maquinaria hidráulica en todo el mundo
IMPERIAL
The ground speed of a track laying vehicle is the hydraulic motor RPM times the circumference of the driving sprocket divided by 168 times 2 times 3.1416 times the overall gear reduction of the power train.
Where:
V = Ground speed in MPH
RPM = Rev. per min. of engine
C = Circumference
C = N x L
N = No. of teeth in sprocket
L = Length of links in inches
R = Overall gear reduction
Example:
Find the ground speed in miles per hour where the motor speed is 1800 RPM, the number of teeth in the sprocket is 41, the length of link 8 inches, is 61 to 1.
C = 41 x 8 = 328
METRIC
V = Ground speed in KPH
L = Length of links in millimetres
Find the ground speed in kilometres per hour where the motor speed is 1800 RPM, the number of teeth in the sprocket is 41, the length of link 200 mm, is 61 to 1.
C = 41 x 200 = 8200
