The transmission part is transmitted by the engine power to the driving wheel through the transmission system to make the tractor run. Mill is a mill composed of power, feeding, grinding and separation system.
The main power and transmission comes from the motor, and the working part is cylindrical from the matching surface at the lower end of the inner and outer grinding heads. Two centripetal ball bearings are used as two main support points above the grinding head, and the cylinders at the lower ends of the inner and outer grinding heads are used as auxiliary support points for rotation. The clearance between the inner and outer grinding heads is adjusted by the axial movement of the inner grinding head.
The ground grain falls directly to the bottom of the drum through the gap between the grinding heads, and the flour and bran are separated from the bottom by the brush with adjustable gap. An electrically driven drilling machine.
It is a conventional product in power tools. The working principle of electric drill is that the motor rotor of electromagnetic rotating or electromagnetic reciprocating small-capacity motor does magnetic field cutting and work operation, and the working device is driven by the transmission mechanism to drive the gear to increase the power of the drill bit, so that the drill bit can scrape the surface of the object and penetrate the object better.
Summary: The power part of tractor is diesel engine, others are motors, and the transmission part is rotating shaft. The transmission part of the mill should be belt drive, and the electric drill is directly connected to the motor. Where the control part is used, it is the control part.
Extended data:
structure principle
Take the integral proportional adjustment type of MD series electric actuators as an example.
The MD series electric actuator adopts AC servo motor as the driving device, and the matching position locator PM-2 control board receives the 4 ~ 20mA DC control signal of the regulating system, and compares it with the position feedback number of the position transmitter.
After comparison, the signal deviation is amplified to turn on the power stage, and the motor rotates to drive the output of the actuator to move in the direction of reducing this deviation (the position transmitter continuously converts the actual position of the output into an electrical signal-the potential excess feedback signal is sent to the position locator) until the deviation signal is less than the set value. At this time, the output of the actuator is stabilized at a position corresponding to the input signal.
