HOOKE’S JOINT:

HOOKE’S JOINT -THAT TRANSMITS ROTATIONAL MOTION

EXACTLY WHAT IS IT?:

EXACTLY WHAT IS IT? It is used to connect two non-parallel & intrsecting axes shafts,having small angle between two axes.

:

IT CONSIST OF:- 1.Two U-shaped yokes or forks which are integral with driving & driven shafts 2.The cross, which is the connecting link The arms of the cross are at right angles.The torque is transmitted from the driving shaft to the driven shaft through the cross.

TYPES OF HOOKE’S JOINTS:

1.SINGLE HOOKE’S JOINT 2.DOUBLE HOOKE’S JOINT TYPES OF HOOKE’S JOINTS

Slide 6:

Driving shaft Driven shaft cross Yokes or Forkes SINGLE HOOKE’S JOINT

Double hooke’s joint:

Double hooke’s joint Driven shaft Driving shaft Intermediate shaft

ADVANTAGES:

ADVANTAGES It can connect two non-parallel & intersecting axes shafts. It is simple in construction.

DISADVANTAGES:

DISADVANTAGES It cannot be used for high speed application. In case of single hooke’s joint, even if the driving shaft is rotating at constant speed, the driven shaft rotates with acceleration.This generates, the inertia torque on the driven shaft.

APPLICATIONS:

APPLICATIONS COUPLING BETWEEN THE GEARBOX & THE DIFFERENTIAL OF AUTOMOBILE(CARS,BUS,TRUCK,ETC). TO TRANSMIT THE DRIVES TO DIFFERENT SPINDLES OF MULTI-SPINDLE DRILLING MACHINE.
