Abstract
A bevel gear system wherein a plastic adaptor of generally frustoconical shape has convergent teeth formed in a recessed frustoconical surface to snap fit over the bevel gear teeth of a more rigid drive gear and similarly has matching gear teeth on an exterior frustoconical surface in mesh with the teeth of a driven bevel gear, which formerly was driven by the teeth of the more rigid gear, and whose axial position has been changed to mesh with the teeth of the adaptor.
Claims12
An adapter bevel gear for interposition between a driving first bevel gear and a driven second bevel gear normally in mesh with said first gear so as to be driven by the latter at a predetermined speed ratio relative thereto, said adapter gear comprising a body formed of resilient material and having an internal, frustoconical cavity of such size as snugly to accommodate one of said first and second gears, said cavity having tooth-accommodating recesses therein for the snug accommodation of each of the gear teeth of said one of said gears, said adapter gear having a frustoconical exterior provided with teeth of such size as to mesh with those of the other of said first and second gears, the number of said external teeth being greater than the number of tooth accommodating recesses in said cavity, thereby to change said ratio.
A method of providing an increased capability for the input shaft of a gasoline pump total sales price computer or the like wherein a drive bevel gear on the output shaft of the gasoline pump variator section is in mesh with a driven bevel gear mounted on a shaft driving the total sales price indicator to indicate the total sales price of the fuel dispensed comprising;
- removing the driven bevel gear from the immediate vicinity of the drive bevel gear;
- fitting a resilient frustoconical adaptor with a greater number of external bevel gear teeth than internal teeth receiving recesses axially over the teeth of the drive gear to dispose the teeth of the drive gear snugly in the teeth receiving recesses;
- and
- resecuring the driven gear in a different position on said elongate shaft in mesh with the exterior bevel gear teeth on the adaptor.
