The size of the gear teeth from the mill, is sub-degree arc length between two adjacent teeth ipsilateral tooth profile (involute) between. Ball size gear modulus is the ratio of the pitch and π (pi) of. Modulus big ball size gear teeth on strong, thick; the size of the gear is great. Ball size gearing as an important part of the ball mill, between the gear and the gear can be a good butt and a well-functioning, in order to ensure normal production throughout the mill. Choose a large ball mill gear material: The Edge of Destruction transmission gear ball size, mainly due to wear and bending and breaking the tooth surface. Therefore, the required gear material having sufficient strength, high wear resistance and good workability. At present, material ball mill generally use a large gear ZG270 ~ 500, ZG310 ~ 570, but subject to normalizing prior to processing, the hardness is reduced HB170 ~ 200. Pinion using 35SiMn, 45MnB, 40Cr and other materials, after quenching, the hardness must be higher than the large ball mill gear up HB220 ~ 250. Ball gear oil: 1. The lower gears and other moving parts wear and extend gear life. 2. Reduce friction and reduce power losses. 3. The dispersion of heat, play a cooling effect. 4. To prevent corrosion and rust. 5. Reduce operating noise and reduce vibration and shock effect between gears. 6. Rinse dirt, especially rushed between the tooth surface dirt, reducing wear and tear.
