A METHOD OF MANUFACTURE OF A GEARBOX AND A GEARBOX MADE BY THE METHOD

摘要

With reference to Figure 1, the present invention provides a gearbox (10) which has: an end stop (40) deformed during manufacture to set an exact spacing in the gearbox (10); bearing surfaces engaging a shaft (12) which are rollerx burnished or swaged; spigots (45-48) which are in a pre-assembly stage of manufacture forced into matching sockets and deformed by this process to set alignment of gearbox casing halves; and a gear (11) which comprises a plastic gear wheel sandwiched between two metal load-bearing elements and secured on the shaft (12) by shoulders rolled in the shaft (12).
