Ex. No. 15 EXERCISE ON REVOLVE

Date:

AIM: To model the given object using the Revolve feature as per the dimensions given.

Description of Revolve Feature:

Command Manager: Features > Revolved Boss/Base

Menu: Insert > Boss/Base > Revolve

Toolbar: Features > Revolved Boss/Base.

Using this tool, the sketch is revolved about the revolution axis. The revolution a xis could be an

axis, an entity of the sketch, or an edge of another feature to create the revolved feature. Note that

whether you use a centerline or an edge to revolve the sketch, the sketch should be drawn on one

side of the centerline or the edge.After drawing the sketch, as you choose this tool, you will notice

that the sketching environment is closed and the part modeling environment is invoked. Similar to

extruding the sketches, the resulting feature can be a solid feature or a thin feature, depending on

the sketch and the options selected to be revolved. If the sketch is closed, it can be converted into a

solid feature or a thin feature. However, if the sketch is open, it can be converted only into a thin

feature.

Ex. No. 18 3D MODELING - FLANGE COUPLING

Date:

Aim : To create the models of the components for the FLANGE COUPLING and assemble these

components together, as shown below. Save this assembly model as Flange Coupling.asm. By using

the SolidWorks software.

Application :

This type of coupling is a protective type flanged coupling, the bolt heads and nuts are shielded by a

peripheral protrusion, called „shroud‟, on each flange is shown in fig.5. Alignment of the two shafts is

independent of the bolts and is ensured by the provision of a turned projection, called „spigot‟, on the

flat face of the one of the flanges which fits into a corresponding recess, called „socket‟, in the other

flange. The length of the spigot projection is kept slightly less than the depth of the socket. The socket

and spigot are turned to give a push fit for accurate alignment of the two shafts. The bolt holes ar

drilled and reamed to give a close running for the bolts in order that the load is taken smoothly

without any impact.

Description:

Each of the flanged bosses is securely keyed to the end of each shaft using a tapered key driven from

inside. While assembling, generally the two flanges are set such that the keys fitted in them are out of

alignment by 90degrees to each other. The two flanges are bolted together by a number of bolts and

nuts. Power is transmitted from one

other through bolts.

RESULT:

The given Machine Component is modeled is modeled using SOLID WORKS software.

which are keyed to the shafts. The two forks are pin joined to a central block, which has two arms at right

angle to each other in the form of a cross. The angle between the shafts may be varied even while the

shafts are rotating.

Description:

Figure shows the details of universal coupling. The forks 2 are mounted at the ends of two shafts 1,

making use of sunk keys 6. The central block 3, having two arms at right angle to each other, is placed

between the forks and connected to both of them by using pins 4 and collars 5. A taper pin (not shown) is

used to keep the pins 4 in position. During rotation of shafts, the angle between them can be varied. Figure

shows the assembly drawing.
