Title: Manufacture of bearing bracket made of thin steel plate
Inventor: ANDO NOBUAKI
IPC: F16C35/067
Filed: 1991-10-31
Abstract: PURPOSE:To discontinue groove processing of a housing corresponding to chamfering of the bearing outer ring in a bearing bracket made of a thin steel plate, processed by drawing. CONSTITUTION:A cylindrical housing 2 and an end face 3 continuing thereto through an R part is formed by drawing a thin steel plate. Afterward or simultaneously, a plurality of circular projections 11 is made by drawing on a circumference of the end face 3 in the vicinity of the housing 2. Inner diameter processings 2a of the housing 2 are cut or ground. If necessary, before or after or simultaneously the treatment of the inner diameter processings 2a, the projections 11 are cut or gound for preparing end face processings 11a. The projections 11 may be ovally or circularly formed. The R part is necessitated in view of theroty of drawing between the housing 2 and the end face 3. In case that the R part is larger than a chamfering measurement of an outer ring of a bearing, and it is projected further than the inner diameter processing 2a of the housing 2 and the end face processing, the projections 11 cover the R part, so that conventional groove processing is dispensed with.
