Once the gear transmission failure of the ramon mill will seriously affect the smooth operation of the grinding mill, it will delay the efficient work of the whole milling production line. Then. What are the reasons for the failure of the high pressure Raymond gear drive?
1, due to the particularity of high-pressure Raymond mill work environment, in grinding operation, gear transmission of the working environment is bad, in affected by dust particles in severe cases, the gear severe pollution. Or the lubricating oil in the gear transmission part is not timely, the lubricating oil pollution is serious, which will cause the high pressure Raymond gear transmission failure.
2. After the gear transmission device has been running for a period of time, the axis of the pinion axis and the ramon grinding scale drum may become unparallel, causing the gear meshing to become a local contact. If the gear is not uniform across the entire tooth width, it is easy to cause the gear shaft to bend and twist. In addition, if the gear transmission material is not uniform, there are slag, stoma and hard particles, etc., and the surface or subsurface layer of local shear stress is too large to produce a broken tooth phenomenon.
3. Stress concentration exists in the gear of high pressure Raymond mill. When the tooth tip of the gear enters the meshing state, the surface layer forms the original crack under the influence of excessive equivalent contact shear stress. In the process of gear operation, the high pressure oil wave produced by contact pressure enters the crack at a high speed, which produces a strong fluid impact on the crack wall. Meanwhile the gear surface crack mouth closed, can be further raise crack within the oil pressure, and forced the further direction and the direction of the tooth surface of crack extension, material fall off from the tooth surface, formation of pitting corrosion.
4. In the transmission, the time for the gear pair to bear the load is greatly extended, which is an important reason for the excessive wear of the gear. However, the reduction of the recombination is necessary to increase the backlash of the gears, so that some impurities and floating objects and dust in the air are more likely to enter the meshing surface of the gear pair, causing the occurrence of abrasive wear.
