Project

AIM:

In this project created motor blower assembly individual parts as per given dimensions an assembled together by considering appropriate constraints in CATIA V5.finally applied the Geometrical tolerances and Dimensions on the Motor blower .

Introduction:

The motor blower assembly consists of 6 parts,those are as below;

1.upper housing

2.Lower housing

3.Motor blower

4.Motor cover

5.shaft

6.Motor

the below shown is 2D sketh of all parts;

Design procedure:

1.Upper housing

It is the outer cover of blow motor assembly,which is acts as a housing to all internal structure and protect from outside environment conditions.in which motor blower and shaft is fitted.

designed the upper house part from the given reference sketch and converted into solid part.it looks as below;

2.Lower housing

it is the another side of blower motor to form closed housing to blower which is located inside of these housings.the upper and lower housing is fix together by using bolts and nuts where holes are provided.

made the sketch of lower housing in sketch work bench as per given sketch and pad it to required thickness to get required solid part of lower housing and provided necessary holes for fitment with respect to the upper housing,which is shown below;

3.Motor blower

An air blower uses to rotating impller /rotor to create the vaccum.this vaccum causes air to rush into blower.the air enetrs the centre of the impeller and divided by the rotating blades.centrifugal force increases the speeof the air and volume of the air stream within the housing.

it consits the number of blades on pheripheral of blower.by considering all design dimension and consideration made the sketch and converte it into solid part as below;

4.Motor cover

This is the cover which is covered the motor and its fan from damage and provides safety to operators.

it is created as per given sketch ,by making sketch revolved it throught the axis to get required shape.then provide the side flanges to fix it to motor body.one side of cover have rectangular slots to cooling purpose.

motor cover is looks as below;

5.Motor

it is the main component in motor assembly .this is drive to run blower by taking input as electricity .

intially made the support body frame an drawn the cylindrical hollow shape on which povide heat exchanging fins.provide shaft mouting throughout the motor body.

6.shaft:

this is the long cylindriacl solid shaft ,which is used to drive the blower by connecting with motor.created it as per drawing with appropraite dimensions and converted into solid part .

after completing the individual part design ,now assembling all parts together in assembly workbench by selecting suitable constraints.

finally the blower motor assembly as below;

GD&T:

This project main objective is to apply GD&T on blower motor assembly parts to get a satisfied components befor going to manufacturing.

GD&T makes the designed components into more acceptable component without making any error and unnecessary manufacturing process on part.it avoids wastage and exatct component at finally.

i applide some GD&T on blower parts after drafting it into 2D sketch ,now it is as below;
