Hand Cranked Generator Set Course Presentation

     The rotational speed output by the motor is fixed, and the reduction of speed can be conveniently achieved by using gears and shafts. For example, by connecting a small gear to the output end of the motor and meshing it with a larger gear, the rotational angular velocity of the larger gear will decrease. Further, by connecting the shaft to another small gear, the circular linear velocity will also decrease.
Gearboxes are generally used in low-speed, high-torque transmission equipment. They convert the power from electric motors, internal combustion engines, or other high-speed rotating sources through the engagement of fewer teeth on the input shaft with the larger teeth on the output shaft to achieve the purpose of speed reduction. Standard gearboxes also use several pairs of gears with the same principle to achieve an ideal speed reduction effect. The ratio of the teeth on the larger to the smaller gears is the transmission ratio.
Gap fits have gaps (including small gaps equal to zero). At this time, the hole's tolerance range is above the shaft's tolerance range. Interference fits have interference (including small interference equal to zero). At this time, the hole's tolerance range is below the shaft's tolerance range. Transition fits may have gaps or interference fits. At this time, the hole's tolerance range overlaps with the shaft's tolerance range.

This course includes three sets of theories: 1. Reduced speed gear theory, 2. Generator theory, and 3. Energy storage and half-wave rectifier charging and discharging theory.

The purpose of the experiment: 1. To understand the structure and principle of gears.
2. Recognize the importance of the application of generators in human life and social development, and understand the continuous development of technology.
