MECHANICAL TRAINING MODEL
- A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which usually mesh with another toothed part to transmit torque.
- Two or more gears working in a sequence are called a gear train.
- These training models are highly useful for demonstrating the most fundamental and frequently used mechanism and are very useful for engineering students.
- All the components are made with a high degree of precision.
- These modules are assembled on transparent Perspex sheets to facilitate teaching.
- They are easy to assemble or disassemble.
- These models help students to understand how the geared train arrangements can produce a mechanical advantage through a gear ratio and thus may be considered as simple machines.
- Also students can appreciate that although the gears in a transmission are analogous to the wheels in a crossed belt pulley system, an advantage of gears is that the teeth of a gear prevent slippage.
