The Spur Gear Assembly Unit, "SGA", allows to study the practical assembly and dismantling of a spur gear with simple tools. The adjustment devices have been designed so that they are assembled manually.
The Spur Gear Assembly Unit, "SGA", consists of a spur gear with spiral gearing. The gear consists of a single reduction stage and a fixed transmission ratio. It is a gear unit composed of: driving and driven shafts, drive wheel and pinion, housing with support and secondary elements such as oil seals, locking rings and bearings. The gearbox is covered by a housing so it belongs to the group of independent gears. These gears are located between the motor and the machine or are used as an integrated module in machines to adapt the speed, direction of rotation and torque to a specific application.
Spiral gears have an advantage over spur gears: With spiral gears, the teeth are not loaded instantly across the entire width, but rather, starting from the edge of the tooth, progressively across the entire width with several teeth engaging simultaneously. For this reason, this type of gearing works more smoothly, avoiding shocks and being almost noise free. Spiral gears are ideal for fast engagement with a high rotation speed, being able to withstand higher loads than spur gears.
The wheels are supplied in a case for easy transport. Also included are a set of tools for assemble and disassemble the unit, and a spare parts kit with parts most prone to wear.
This equipment is perfect for working in a practically self-sufficient way, in groups of up to three students.
The teaching material includes technical drawings with a list of parts, dimensional drawings of the components and the necessary instructions, duly illustrated, to perform the proposed practical exercises in an appropriate manner.
