TEORÍA DE MOVIMIENTO

TREN SIMPLE POLEAS

N=RPM DEL MOTOR

D= PULGADAS POLEA MOTRIZ

d=PULGADAS POLEA MOVIDA

n=RPM DE LA ULTIMA POLEA

FORMULA

n=ND/d

EJEMPLOS:

MOTOR 

CALCULAR VELOCIDADES

n=?

n=ND/d

n=(1200rpm)(8)/10 =960rpm.

TREN SIMPLE ENGRANES

n=rpm del ultimo engrane

N=rpm del motor

Z= # de dientes motriz

&= #de dientes movido

CALCULAR VELOCIDADES

n=NZ/&

n=(1500rpm)(80)/60 =2000rpm

CALCULAR VELOCIDADES

n=NDDDDD.DDDD/ddddddd.ddddd

n= (1320rpm)(8)/(10)=1056rpm

n=(1056)(12)/18=704rpm

CALCULAR VELOCIDADES

n=(2050rpm)(14)/20=1435rpm

n=(1435rpm)(30)/45= 956.66rpm

CALCULAR VELOCIDADES

LOS ENGRANES INTERMEDIOS SE ELIMINAN SOLO SE CUENTA EL ULTIMO ENGRANE MOVIDO COMO APARECE EN LA FROMULA APLICACION EJERCICIO.

n=(1200rpm)(80)/90=1066.66rpm

POLEAS Y ENGRANES

CALCULAR VELOCIDADES

n1=(2200rpm)(10)/20=1100rpm

n2=(1100rpm)(18)(30)/10(40)=1485rpm

n3=( 1100rpm)(18)/30=660rpm

n4=(1100rpm)(18)(30)/10(80)=742.5rpm

n5=(1100rpm)(18)/22=900rpm
