Lapping of Gears

Gear Lapping Compound
Gear Lapping Compound is utilized in the finishing process of
hypoid and other types of matched gears in the lapping machines.
This results in a noise free meshing in between the lapped machines. |

After the hardening process is over the Gears and pinions are
lapped. This ensures smooth and quiet running. Lapping is done in a lapping
machine by running together of mating pairs. A liquid abrasive compound is
fed under pressure into the gear pair. With gears rotating, this compound is
able to remove small amounts of metal. The end result is refining of the
tooth surface and getting the desired contact pattern. (Image showing a
lapping process) With the advent of other finishing processes the lapping
process has come under a bit of cloud especially from the fine grinding
method. Let's see the major points of difference between the two.
Lapping Machine
There are a variety of Gear lapping machines available for use in the
lapping operations. Features to look for in the gear lapping machine
includes:
- Automatic workpiece meshing
- Automatic backlash
- Swing speed controller infinitely variable
- Hydraulic chucking
- Hydraulic brake
