This document discusses the maintenance of a line shaft and its applications. It provides background on line shafts and how they were historically used to transmit power from central sources to machinery throughout workshops. It then details the specific maintenance performed on an installed line shaft, including lubricating jammed bearings and pulleys, replacing worn belts, and realigning misaligned pulleys. The objective of maintaining this line shaft was to make it functional again for demonstrating its use in industrial applications like farming and grinding operations.

4. ACKNOWLEDGEMENT:
I am very grateful to DEPARTMENT OF MECHANICAL ENGINEERING, BIT
SINDRI for providing us with this opportunity to undertake this project and get a first
hand exposure to the skill of Mechanical Maintenance. The work done in any such
project is never a single person’s effort but a combined effort of a group of persons.
Thus before the technical presentation of our report, a word of thanks to all who had
been a part of this.
I would like to extend my sincere gratitude to my Project Guide Prof. (Dr.)
CHAITANYA SHARMA, Associate Professor, Department of Mechanical
Engineering for his patronage and giving us an opportunity to undertake this project.
Last but not the least we would like to thank Almighty without whose blessings this
project would not have been possible.

5. PROBLEM STATEMENT:
• The main shaft was very hard to rotate and was jammed due to not in
continuous operation from long time.
• The pulleys were jammed and also the motor was not running smoothly.
• The belts over pulleys were worn and torn out and the belts were
slackened due to which it was slipping over the pulleys.
• The bearings on which the main shaft was mounted was working noisy due
to lubrication (Grease) dried out.
• The pulleys position mounted on the shaft was misaligned and the whole
machine was dusty.

6. WHY IS THE
PARTICULAR TOPIC
CHOSEN:
 Having keen interest towards working in Manufacturing
Application & Maintenance related Domain, we would get
a good exposure and learning environment towards
working in the field of manufacturing & maintenance and
from the technical learnings obtained after the completion
of the project, we could be able to implement our
knowledge in different sectors like Iron and Steel sector,
automobile sectors, and other industries involving
manufacturing as their core domain of work & their
maintenance.

7. VIEW OF INSTALLED LINESHAFT AT WORKSH

8. WHAT IS LINE SHAFT &
APPLICATION ?
A line shaft is a power-driven rotating shaft for power transmission that was used
extensively from the Industrial Revolution until the early 20th century. Prior to the
widespread use of electric motors small enough to be connected directly to each piece of
machinery, line shafting was used to distribute power from a large central power source to
machinery throughout a workshop or an industrial complex. The central power source
could be a water wheel, turbine, windmill, animal power or a steam engine. Power was
distributed from the shaft to the machinery by a system of belts, pulleys and gears known
as millwork.

THERE ARETHREE BEARINGS ONTHE MAIN LINE OF LINESHAFTWHICHWERE INITIALLY JAMMED
DUETO NOT IN USE SINCE LONGTIME.THE GREASEAND OIL INSIDETHE BEARINGARE
DRIED.THEYARE ALSO COVEREDWITH DUST AND NEEDTO BE MADE FREETO ROTATE BY
GREASING & OILING BY APPLICATIONOF SUITABLEAND GOOD LUBRICANTS,AFTER LUBRICATION
THEYWOULD BE FREETO ROTATEAND READYTO USE.

12. #2. PULLEYS :
THEREARETWOTYPES OF PULLEYS ONE MOUNTED ON MAIN SHAFT OF LINESHAFTAND OTHER
ONTHE COUNTERSHAFT.THESE PULLEYSWERE JAMMED DUETO PROLONGED NO USE OFTHE
MACHINARY.THEYWEREALSO FULL OF DUST .THEY NEEDTO BE MADE FREETO ROTATE BY
GREASING,OILINGOR LUBRICATION BY USING SUITABLE LUBRICANTS.ONCETHEY ARE MADE
THEY ARE FREETO ROTATE AND READYTO USE.

13. METHODOLOGY:
 The line shaft is used to transfer power to multiple
machines like Lathe machine which is used in
turning operations and Grinding machine through a
primary motor.
 The power is transferred from the line shaft to
different operating machines via pulleys and belts.
 The power is then transferred to multiple lathe
machine and grinding wheel.
 Hence multiple jobs are done simultaneously.

14. TOOLS USED:
 Open End Spanner
 Ring Spanner
 Screw Driver
 Ball Pein Hammer
 Measuring Tape
 Sand Paper

15. OBJECTIVE & SCOPE OF THE PROJECT:
The Primary objective of the project was maintenance of not
functional Line Shaft machine, so that it may be used for
demonstration in farming, grinding operations and Industry fit.
Improving Products life creates new scopes for growth and
development of the country with advancement in technology to
reach to a greater height in future
