ACKNOWLEDGEMENT
My industrial training in HV Transmissions Ltd was a very enlightening experience as I learnt a lot of new things. I would like to thanks HV Transmissions Ltd for giving us the opportunity to do our training here.
I sincerely acknowledge my heartfelt gratitude to Mr Satish Kumar & Mr Gowri Shankar Rabidas who spared their valuable time in providing the necessary inputs for completing the project.
My sincere thanks to Mr K.K.Ghosh (A.G.M.-PE&TOOLS, NPI AND MKTG, HVTL) for assigning and giving me an opportunity to learn the fundamentals related to design of automotive transmissions.
Last but definitely not the least, a big thanks to all the peoples related to the project in the shop floor for their help who helped a lot in gathering the information related to the project.
PREFACE
This report is an integral part of the project work that a Mechanical Engineering in is necessitated to undergo. The period of this training was of one month. It is conducted at the fag end of the 2nd year; when a student is well versed with the technical know-how in Mechanical Engg.
The training gears up a student for their though professional career ahead. In fact a student is introduced to industrial & allied application of Mechanical Engg., which they have been learning for the last years. The importance of this project training is judged from the fact; the absorption of fresh outgoing students into the corporate world is manifold dependent on the project & the critical comments of the authorities on it.
This report encompasses all minutest of details of the project work & the emphasis was focused to prevent any details to be left out to weed out all under forced. Errors, which may get have crept in, is regretted.
INTRODUCTION TO MECHANICAL ENGINEERING
Mechanical engineering is one branch in the field of engineering. Mechanical engineering generally focuses on the creation and evaluation of physical things, but covers a broad range of technical areas.
Because mechanical engineering focuses on the study of physical systems, the core courses in a mechanical engineering curriculum reflect this. Most mechanical engineers start their learning with basic physics and calculus courses. Later courses can include static and dynamic systems, strength of materials, fluids, thermodynamics and heat transfer. A mechanical engineering curriculum is usually rounded out with advanced classes that match the student's desired specialty.
Design Engineering is a broad topic that refers to the mechanical or physical design of an object or system. The primary tool for the design engineer, after paper and pencil, is computer-aided design (CAD) software.
This branch focuses on the design and analysis of structural systems, such as bridges, buildings and large mechanisms.
Engineers in this branch of mechanical engineering have a solid understanding of the mechanical behavior of things, but also have a background in instrumentation, data acquisition, and design of experiments.
Organisational Environment:
HV Transmissions was incorporated on 13th March 2000. Carved out of the Gear-Box manufacturing unit of Tata Motors, Jamshedpur, the facilities of HVTL are located within the Campus of Tata Motors. HVTL is a subsidiary of Tata Motors with Tata Capital being the only other stake-holder with 15% stake. The primary objective of creating this company is to develop & sustain a specialist focus on gear-boxes for TML while TML focuses on integration of aggregates. The business model is therefore built around providing the highest value in terms of cost, technology & delivery of transmissions to the principal customer & share-holder TML.
HV Transmissions Limited is a leading manufacturer of automotive transmissions, components & engineering applications for a wide range of medium & heavy commercial vehicles.
Products, Services & Delivery Mechanisms:
HVTL manufactures & delivers Gear Boxes and their after-market spares components for the M&HCV range of commercial vehicles of Tata Motors Ltd. The range of Gear-Box Assemblies (aggregates) covers 6 major platforms: GBS-40, GBS-50, GBS-600, GBS-680, GBS-750, GBS-1150 & Auxiliary Gear-Boxes and variants in excess of 110 nos. Delivery of products is direct to various locations of Tata Motors. Gear Boxes are used in vehicles as a unit which converts the Engine RPM & torque to various levels of vehicle torque & speeds requirements. At the OEM customer end, they are first assembled onto the engines using a Clutch mechanism in between and then the whole assembly (Engine & Gear-box) is dropped into bare chassis on assembly lines.
After-market parts relate to parts that are assembled inside the gear-box. During replacement, the gear-box is dismantled from the vehicle, disassembled to include changed parts, re-assembled and re-integrated with the vehicle by mechanics.
