Abstract
Abstract A bearing arrangement for a tilting trunnion of a metallurgical vessel, in particular a converter in a steel making plant, has an inner race, an outer race, bearing bodies arranged therebetween, and at least one sensor device with a sensor pin. The sensor device penetrates the outer race and contacts the inner race forming a sensing point. Also, the sensor device has a fixed point with the sensor pin being movable relative to the fixed point and the distance between the sensing point and the fixed point being measurable.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
130 words
In a bearing arrangement for a tilting trunnion of a metallurgical vessel, in particular for a converter in a steel making plant, of the type including a bearing within a bearing housing, having an inner race, an outer race and bearing bodies arranged therebetween, the improvement comprising at least one sensor means for measuring changes in the weight of the vessel contents or the wear of the bearing and having a sensor pin, which at least one sensor means penetrates the outer race of the bearing and contacts the inner race thus forming a sensing point, the at least one sensor means also having a fixed point with the sensor pin being movable relative to the fixed point, the distance between the sensing point and the fixed point being measurable.
Claim 2
Dependent Claim
130 words
In a bearing arrangement for a tilting trunnion of a metallurgical vessel, in particular for a converter in a steel making plant, of the type including a bearing within a bearing housing, having an inner race, an outer race and bearing bodies arranged therebetween, the improvement comprising at least one sensor means for measuring changes in the weight of the vessel contents or the wear of the bearing and having a sensor pin, which at least one sensor means penetrates the outer race of the bearing and contacts the inner race thus forming a sensing point, the at least one sensor means also having a fixed point with the sensor pin being movable relative to the fixed point, the distance between the sensing point and the fixed point being measurable.
Claim 3
Dependent Claim
16 words
A bearing arrangement as set forth in claim 1, wherein said bearing bodies are rolling bodies.
Claim 4
Dependent Claim
16 words
A bearing arrangement as set forth in claim 1, wherein the bearing bodies are sliding bodies.
Claim 5
Dependent Claim
26 words
A bearing arrangement as set forth in claim 1, wherein the fixed point of the at least one sensor means is arranged on the bearing housing.
Claim 6
Dependent Claim
30 words
A bearing arrangement as set forth in claim 1, further comprising a bearing support, the fixed point of the at least one sensor means being arranged on said bearing support.
Claim 7
Dependent Claim
43 words
A bearing arrangement as set forth in claim 1, wherein the sensor pin is arranged so as to be vertically aligned with the middle of the bearing below the tilting trunnion in order to measure changes in the weight of the vessel contents.
Claim 8
Dependent Claim
42 words
A bearing arrangement as set forth in claim 6, further comprising a second sensor pin arranged so as to be vertically aligned with the middle of the bearing above the tilting trunnion in order to additionally measure the wear of the bearing.
Claim 9
Dependent Claim
55 words
A bearing arrangement as set forth in claim 6, wherein the bearing is a pendulum roller bearing having two rows of pendulum rollers as bearing bodies and a middle web provided on the inner race and located between the two rows of pendulum rollers, the sensor pin contacting the inner race at said middle web.
Claim 10
Dependent Claim
31 words
A bearing arrangement as set forth in claim 8, wherein the middle web is designed so as to have a spherical face whose center lies at the center of the bearing.
Claim 11
Dependent Claim
40 words
A bearing arrangement as set forth in claim 1, wherein the sensor pin is arranged so as to be vertically aligned with the middle of the bearing above the tilting trunnion in order to measure the wear of the bearing.
Claim 12
Dependent Claim
55 words
A bearing arrangement as set forth in claim 10, wherein the bearing is a pendulum roller bearing having two rows of pendulum rollers as bearing bodies, and a middle web provided on the inner race and located between the two rows of pendulum rollers, the sensor pin contacting the inner race at said middle web.
Claim 13
Dependent Claim
31 words
A bearing arrangement as set forth in claim 11, wherein the middle web is designed so as to have a spherical face whose center lies at the center of the bearing.
Claim 14
Dependent Claim
127 words
A bearing arrangement as set forth in claim 1, wherein the bearing is a pendulum roller bearing having two rows of pendulum rollers as bearing bodies, and a middle web provided on the inner race and located between the two rows of pendulum rollers, the sensor pin being arranged so as to be vertically aligned with the middle of the bearing below the tilting trunnion and contacting the inner race at said middle web in order to measure changes in the weight of the vessel contents, a second sensor pin being located so as to be vertically aligned with the middle of the bearing above the tilting trunnion and also contacting the inner race at said middle web in order to measure the wear of the bearing.
Claim 15
Dependent Claim
31 words
A bearing arrangement as set forth in claim 13, wherein the middle web is designed so as to have a spherical face whose center lies at the center of the bearing.
