The small crane turntable due to material porosity or interlayer, the raceway hardness of hardened layer depth, swim uneven manufacturing quality problems or some external reasons caused by raceway spalling or hardened gear tooth broken, will enable the small crane is not working properly.
For the raceway peeling layer, we must first make a correct judgment. Peeling occurs, generally not easy to see in the outside. According to our experience, south the following conditions, that is: the host raceway delamination with load rotation, raceway "Ker - Ker" noise, rotation speed uneven or a range of speed slowed down and accompanied by a slight vibration; rotary speed reducer machine temperature is too high or too large current; the rotary gear reducer and hydraulic coupling or coupling the keyway is squeezed bad etc..
After peeling, must be repaired in time. Otherwise, the area will be expanded, so that the entire small crane turntable scrapped.
Repair method is: first small crane turntable in the roller or ball out, the inner and outer ring raceway and separation; gasoline to clean; then with grinder (wheel) will be carefully around the crack has occurred in the hardened layer of abrasion, delamination will bottom smooth; the welding and cutting torch raceway supplement weld preheating, welding used in carbon steel electrode (electrode must be used before drying, and with baking with), to make the welding layer is slightly higher than the raceway surface of 1-2mm; if the delamination depth or larger, should be layered and segmented welding, do not make the parent material caused by high temperature deformation; this prevents rapid cooling welding cracks, after welding should immediately take insulation measures, so that he gradually cooling. After cooling with grinder grinding welding layer, making it slightly higher than the raceway surface, using an oilstone or emery cloth grinding metallographic gradually repair welding layer, making it highly consistent with normal raceway surface, with the corresponding original curvature detection model, until qualified; cleaning with gasoline raceway and roller (steel ball). Lubricating grease, assembling can be completed.
The repair method is local welding or insert repair method, local welding is: first the residual matrix crack damaged parts by hand wheel grinding, gasoline (oil) to clean the torch for this position; preheating, when reaches a certain temperature, using carbon steel electrode in wheel tooth damaged parts push welding the teeth of the prototype, which is 1-2mm higher than the party tooth surface; send experienced benchwork, according to profile template detection, until the tooth shape to meet the requirements so far.
When a small crane turntable of the tooth is damaged, can be cut along the root, then the root file into shape. On the same kind of waste gear ring, the next tooth is cut and processed into the corresponding shape of the base metal. In order to ensure the consistency of tooth distance, and use double screw chuck value-added tight after welding of low carbon steel in the teeth around. Finally, with a file and other tools to ensure weld flattening, meshing augmentation can be.
