Gear teeth can be produced entirely by grinding, entirely by cutting, or by first cutting and then grinding to the required dimensions. Usually, gear grinding is performed after a gear has been cut and heat-treated to a high hardness; grinding is necessary for parts above 350 HB (38 HRC), where cutting becomes very difficult. Teeth made by grinding are usually those of fine pitch, where the amount of metal removed is very small. In addition, grinding of gears becomes the procedure of choice in the case of fully hardened steels, where it may be difficult to keep the heat-treat distortion of a gear within acceptable limits. Lastly, in a few cases, medium-hard gears that could be finished by cutting are ground in order to save costs on expensive cutting tools such as hobs, shapers or shaving cutters, or to get a desired surface finish or accuracy on a difficult-to-manufacture gear.
Our services range from standard inspections and repairs to complete overhauls. A repair or overhaul of a gearbox generally consists of an Inspection, Repair/Modification and a final Report.
Inspection
The first step when repairing any gearbox is the inspection. Gearbox inspections include:
When the inspection is finished, an inspection report is drawn up with recommendations for repair.
