Engine Timing Gear Principle and Introduction
Engine timing gear principle: These systems have a continuous relationship with the completion of mechanical functions. Timing gears are introduced into the intake and exhaust systems of internal combustion engines and partial systems of clocks and watches.
Engine timing gear introduction: The positive and negative gears of automobile engines are driven by toothed belts, which have the advantages of simple structure, low noise, stable operation, high transmission accuracy and good synchronization, but low strength. After long-term use, it is easy to age, stretch and deform or break.
The toothed belt is in the outer cover, in a closed state, and then observe its working state. The timing gear is a gear that can position the time scale in mechanical equipment to complete the related control function.
The engine gear is a mechanical transmission device whose function is to transmit the torque of the engine to other components, thereby realizing the power transmission of the engine. Service conditions: 1. In order to ensure its wear resistance and corrosion resistance, the gear material must have good hardness and strength; in order to ensure its correct installation and transmission efficiency, the gear size must be accurate; 3. In order to ensure its transmission efficiency, The surface of the gear must be smooth; 4. In order to ensure the normal operation of the gear, it must be well lubricated; 5. In order to ensure the normal operation of the gear, it must be installed correctly.
Stress situation: Gears are subjected to many forces in an engine, among which torque, friction, shock and vibration are important. Torque is generated by the engine, which is the main force of gear transmission; friction is generated by the friction between gears, which will affect the transmission efficiency of gears; shock is caused by sudden changes in the engine, which will affect the accuracy of gears; vibration is Caused by the vibration of the engine, it will affect the accuracy and life of the gear.
