Failure Analysis of High Pressure Raymond Gear Transmission

In high-pressure Raymond Mill operation, gear failure is one of the more common faults. Once the Raymond grinding gear failure, will seriously affect the smooth operation of the milling operation, delayed the efficient operation of the entire milling production line. Then High-pressure Raymond gear failure causes what?

1, Due to the special working environment of the high-pressure Raymond mill, the work environment of the gear transmission is poor when the milling operation is carried out. Under the circumstance of being seriously affected by the dust particles, the gear pollution is serious. Or gear transmission parts of the oil is not added in time, serious oil pollution, will lead to high pressure Raymond gear failure.

2, after a period of operation of the gear transmission, the axis of the pinion and the axis of the Raymond mill grading roller may become non-parallel, causing the gear to mesh to become a partial contact. If the gear in the entire tooth width force uneven, it is easy to cause the gear shaft bending and torsional deformation. In addition, if the gear transmission material is not uniform, there are slag inclusions, pores and hard particles, the surface or subsurface local shear stress is too large, resulting in broken teeth phenomenon. The company is located in:

3, there is stress concentration on the high-pressure Raymond grinding gear, when the gear tooth top into meshing state, under the effect of excessive equivalent shear stress, the surface layer of the formation of the original crack. During gear running, the high-pressure oil wave generated by the contact pressure enters the crack at an extremely high speed and exerts a strong fluid impact on the crack wall. At the same time, the surface of the gear pair can close the crack opening and further increase the oil pressure in the crack Rise, and forcing the crack to the direction of depth and tooth surface expansion, the material off from the tooth surface, the formation of pitting.

4, in the transmission gear single tooth to withstand the load time to be greatly extended, which is caused by gear wear too fast an important reason. The reduced coincidence will inevitably lead to gear backlash increases, so that some impurities and airborne debris and dust easier to enter the meshing surface of the gear pair, causing abrasive wear occurs.
