Abstract
Abstract A safety mounting for large antifriction bearings comprises rolling members disposed at a first bearing ring, a second bearing ring engages the rolling members, and a combined attachment and retainer provision is disposed at the first bearing ring and positively locks the second bearing ring. The attachment aspect of the provision provides for mounting of connecting constructions to the bearing ring. These safety mountings are particularly suited for large antifriction bearings at excavators, dredgers and cranes. The combined attachment and retainer provision allows to save material, space and time.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
105 words
Safety mounting for large antifriction bearings comprising a first bearing ring; rolling members disposed at the bearing ring; a second bearing ring engaging the rolling members such that the second bearing ring can rotate versus the first bearing ring; a circular radial projection disposed on the second bearing ring on the side located toward the first bearing ring and extending coaxially relative to with the bearing axis; and combined attachment and retainer provision disposed at the first bearing ring on the side toward the second bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 2
Dependent Claim
105 words
Safety mounting for large antifriction bearings comprising a first bearing ring; rolling members disposed at the bearing ring; a second bearing ring engaging the rolling members such that the second bearing ring can rotate versus the first bearing ring; a circular radial projection disposed on the second bearing ring on the side located toward the first bearing ring and extending coaxially relative to with the bearing axis; and combined attachment and retainer provision disposed at the first bearing ring on the side toward the second bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 3
Dependent Claim
19 words
The safety mounting for large antifriction bearings according to claim 1 wherein the bearing supports a goods lifting machine.
Claim 4
Dependent Claim
33 words
The safety mounting for large antifriction bearings according to claim 1 wherein the combined attachment and retainer provision comprises attachment nuts with a collar screwed onto bolts retained in the first bearing ring.
Claim 5
Dependent Claim
51 words
The safety mounting for large antifriction bearings according to claim 1 wherein the combined attachment and retainer provision comprises attachment bolts retained in the first bearing ring and provided with a set collar for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 6
Dependent Claim
50 words
The safety mounting for large antifriction bearings according to claim 1 wherein the combined attachment and retainer provision comprises attachment bolts retained in the first bearing ring and provided with a washer for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 7
Dependent Claim
50 words
The safety mounting for large antifriction bearings according to claim 1 wherein the combined attachment and retainer provision comprises attachment bolts held in the first bearing ring and retaining a retainer ring for forming an opening means and positively locking the second bearing ring by overlapping the circular radial projection.
Claim 8
Dependent Claim
25 words
The safety mounting for large antifriction bearings according to claim 6 wherein the retainer ring is provided by way of a plurality of ring segments.
Claim 9
Dependent Claim
32 words
The safety mounting for large antifriction bearings according to claim 6 wherein the retainer ring is provided with tapped holes and is connected directly via the tapped holes to the attachment bolts.
Claim 10
Independent Claim
120 words
A method for safe mounting of antifriction bearings comprising positioning a first bearing ring; disposing rolling members at the first bearing ring; disposing a circular radial projection on a second bearing ring on the side to be located toward the first bearing ring and coaxial with the bearing axis; engaging the rolling members with a second bearing ring such that the second bearing can rotate versus the first bearing ring; and attaching and retaining at the same time the second bearing ring via a combined attachment and retainer provision of the first bearing ring on the side toward the second bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 11
Independent Claim
120 words
A method for safe mounting of antifriction bearings comprising positioning a first bearing ring; disposing rolling members at the first bearing ring; disposing a circular radial projection on a second bearing ring on the side to be located toward the first bearing ring and coaxial with the bearing axis; engaging the rolling members with a second bearing ring such that the second bearing can rotate versus the first bearing ring; and attaching and retaining at the same time the second bearing ring via a combined attachment and retainer provision of the first bearing ring on the side toward the second bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 12
Dependent Claim
53 words
The method for safe mounting of antifriction bearings according to claim 9 wherein the attaching and retaining is provided by employing attachment nuts having a collar screwed onto bolts retained in the first bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 13
Dependent Claim
55 words
The method for safe mounting of antifriction bearings according to claim 9 wherein the attaching and retaining is provided by employing attachment bolts retained in the first bearing ring and pressing by way of a set collar for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 14
Dependent Claim
51 words
The method for safe mounting of antifriction bearings according to claim 9 wherein the attaching and retaining is provided by employing attachment bolts retained in the first bearing ring and pressing against washers for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 15
Dependent Claim
53 words
The method for safe mounting of antifriction bearings according to claim 9 wherein the attaching a retaining is provided by employing a retainer ring kept in position by bolts held by the first bearing ring for forming an opening means and positively locking the second bearing ring by matching the circular radial projection.
Claim 16
Dependent Claim
30 words
The method for safe mounting of antifriction bearings according to claim 13 further comprising tapping a hole in the retainer ring and directly attaching the retainer ring to the bolts.
