Abstract
Retaining bushing for securing bearing rings comprising a strip of sheet metal bent to form a cylinder having radially projecting retaining projections engaging in a positively locking fashion in grooves in the bearing rings, the retaining projections being distributed around the periphery and being raised up from the sheet material in the radial direction by deep-drawing and stamped out to the required width along a circumferential line around the retaining bushing.
Claims6
A retaining bushing for securing bearing rings, comprising:
- a cylindrical retaining ring including an axial slot along its entire length;
- said ring having circumferentially spaced, radially outwardly projecting retaining projections about its periphery arranged in two axially spaced rows, said projections having a surface which slopes relative to a radial plane forming an outer portion and an inner portion with an opening whereby the axial distance between the surfaces is greater at the outer portion of the projection than at the inner portion which is adjacent the ring;
- and
- said retaining projections locking into radial grooves in the bearing rings to secure the bearing rings in abutting end to end relation.
In an assembly for connecting two annular members in abutting end to end relationship, a retaining bushing comprising:
- a cylindrical retaining ring split by an axial slot to permit radial contraction and expansion of said retaining ring, radially projecting retaining projections spaced circumferentially about the periphery of said retaining .ring arranged in two axially spaced rows, said projections having a surface which slopes relative to a radial plane forming an outer portion and an inner portion with an opening therebetween whereby the axial distance between the surfaces is greater at the outer portion of the projection than at the inner portion which is adjacent the ring;
- and
- said retaining projections locking into radial stepped grooves in the annular members to secure the annular members in the abutting end to end relationship whereby the inner circumferential surface of said retaining ring is flush with the inner circumferential surfaces of the annular members.
A retaining bushing for securing bearing rings, comprising a cylindrical retaining ring including an axial slot along its entire length;
- said cylindrical retaining ring having circumferentially spaced, radially outwardly projecting retaining projections about its periphery arranged in two axially spaced rows, said projections having a surface which slopes relative to a radial plane forming an outer portion and an inner portion with an opening therebetween whereby the axial distance between the surfaces is greater at the outer portion of the projection than at the inner portion which is adjacent the ring;
- and
- said retaining projections locking into radial grooves in the bearing rings to secure the bearing rings, said retaining projections including a confronting edge on the outer portion sloped relative to the radius of said retaining ring whereby upon said locking of said retaining projections into the radial grooves, the bearing rings slide down said sloped confronting edges into the locking position.
