Engineering Models in Chennai

The apparatus consists of a variable speed D.C. Motor, Driving pulley and Driven pulley of equal diameter. The pulleys are mounted on input shaft (Motor shaft) and output shaft. The driven pulley can slide on the base with bearing block to change initial tension in belt. Brake drum is mounted on output shaft helps to measure power output. The motor speed is varied by dimmerstat. A two channel RPM Indicator is provided to measure speeds of driven and driving pullies respectively. EXPERIMENTATION : 1. To measure co-efficient of friction between pulley material and different belt materials. 2. To measure power transmitted with varied belt tensions and plotting graph of (T1 T2).Tension Characteristics 3. To measure percentage slip at fixed belt tension by varying load on brake drum and plot graph of (T1-T2) Vs.percentage slip.i.e. Slip Characteristics. Finding a creep zone from graph. 4. To measure belt slip speed and observe the limiting value float at constant speed when the slip just starts. SPECIFICATIONS : 1.D.C. Motor 1 HP, 1500 RPM, variable speed. 2.Driving Driven puilies of equal diameters. 3.Brake drum along with spring balance. 4.Fiat Belt of fixed length of following materials (i)Fabric Belt (ii)Canvas Belt.

Mechanical engineering models are representations or prototypes of mechanical systems, components, or processes used to visualize, analyze, or test designs before physical production. These models can range from basic conceptual sketches to highly detailed computer simulations or physical prototypes. They are used to evaluate the functionality, performance, and manufacturability of mechanical components and systems.Here’s a breakdown of different types of mechanical engineering models and their importance in the field:Types of Mechanical Engineering Models:Conceptual Models:These models are often simple sketches or diagrams that represent the initial design concepts for a mechanical system or component. They help engineers understand the basic functionality and layout of the system before moving to more complex design stages.Purpose: To explore ideas and communicate the basic function of the design.

Engineering model makers build precise 3D physical and digital replicas of industrial machinery, plants, and structural designs. Key features include high dimensional accuracy, multi-material fabrication (such as acrylic, metal, and 3D printing), integration with CAD data, functional moving parts, and clear visual communication for technical reviews and client presentations

The Caterpillar C-series, Cummins ISB and B-series, Detroit Diesel Series 60, and other models from Perkins, Yanmar, and Eicher are notable examples of diesel engine models, which range in size from tiny industrial and agricultural engines to enormous marine and locomotive engines. Applications for these are numerous and include industrial equipment, vehicles, trucks, and generators.

Owing to the years of industrial experience, we have been able to serve our valued clients with high quality 3d models. 3D models can save time and effort while increasing productivity. For the construction process, the 3D model is built along with the design so any interference between productivity is immediately highlighted. All issues can be addressed in the initial stage so that when construction begins everything progresses smoothly across all disciplines, be that civil, mechanical, piping, electrical, or instrumentation.

Cylinder: The combustion chamber where the air-fuel mixture is ignited, initiating the power stroke. Piston: Moves up and down within the cylinder to compress the mixture and deliver power to the crankshaft. Crankshaft: Converts the linear motion of the piston into rotational motion, driving output power. Camshaft: Operates in sync with the crankshaft to open and close intake and exhaust valves at precise timings. Valves (Intake Exhaust): Control the entry of air-fuel mixture into the cylinder and expulsion of exhaust gases. Spark Plug: Produces the spark needed to ignite the compressed air-fuel mixture during the power stroke. Connecting Rods: Link the piston to the crankshaft, transmitting the piston's motion to the rotating crankshaft. Timing Gears: Ensure accurate synchronization between crankshaft and camshaft rotation, essential for efficient valve operation. Key Features Operates on the four-stroke principle for fuel efficiency and emission control Equipped with timing gears for synchronized valve timing Combines mechanical and electrical systems (e.g., camshaft, spark plug) for coordinated combustion Supports air or water cooling, depending on design requirements Delivers smooth and continuous power output over each cycle Applications Automobiles and motorcycles Portable generators Agricultural and industrial machinery Lawn mowers and small construction equipment
