As is well known to the public, the rotation of the Raymond mill is mainly driven by gears. If the gears are not in good condition, the Raymond mill does not work under normal conditions. Therefore, it is necessary to understand the transmission characteristics of the gears of Raymond Mill.
The transmission characteristics of the gears of the Raymond mill are at the following six points:
1: Widely used, a wide range of transmission power and speed. The instrument gear has a minimum diameter of less than 1 mm and a heavy gear has a diameter of more than 10 m. The power transmitted through the gear can be 100,000 kW, the peripheral speed is 300 m/s, and the speed is 10,000 rpm.
2: Accurate transmission ratio, stable operation, accurate and reliable transmission activities.
3: High transmission efficiency, generally 0.94-0.99; small wear and rear, long service life.
4: Compact structure, large realizing transmission rate. In general, the gear ratio of the circular gear is 5-8, and the combination of various shifting and commutation can be realized.
5: Gear manufacturing and installation accuracy requirements are high. The gears should be processed and specialized equipment manufactured by sophisticated technical methods as a costly result.
6: The distance between the transmission axis to be used and the center is large, which is not applicable.
