Abstract
Abstract An arrangement for measuring a radial force applied to a roller bearing of a device has an inner element connected with the roller bearing for joint displacement therewith under the action of this force, an outer element mountable on the device and outwardly surrounding the inner element so as to form a gap therebetween, and a web extending through the gap and connecting the elements with each other. The web is stressed in response to displacement of the inner element with the roller bearing in a generally radial direction of the gap, whereby signals commensurate with the degree of stressing of the web are originated. The elements may be formed as rings concentric with each other, and the web may extend in the radial direction of the rings. Instrumentalities are provided for transmitting the above signals, such as electrical signalling instrumentalities. The latter may include two strain gauges mounted on the web. An arrangement may be provided for limiting the displacement of the inner element relative to the outer element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A bearing mounting unit for measuring a radial force applied to the mounted bearing, said unit comprising a unitary bearing mounting member having an outer annular portion and an inner annular portion surrounded by said outer annular portion ad defining therewith an annular gap, and a web extending across said gap and being of one piece with said portions so as to support said inner annular portion with freedom of radial displacement relative to said outer annular portion, said inner annular portion having an inner circumferential surface for receiving and retaining therein a rolling contact bearing, said inner and outer annular portions having respective faces which together bound said gap and which are provided at diametrically opposite locations with sets of concave recesses having open sides facing one another across said gap; a pair of overload protecting pins each received in one of said sets of concave recesses and extending parallel to one another and to a central axis of said member; and means mounted on the web for originating and transmitting signals commensurate with the stressing of said web resulting from the radial displacement of said inner annular portion relative to said outer annular portion.
Claim 2
Dependent Claim
196 words
A bearing mounting unit for measuring a radial force applied to the mounted bearing, said unit comprising a unitary bearing mounting member having an outer annular portion and an inner annular portion surrounded by said outer annular portion ad defining therewith an annular gap, and a web extending across said gap and being of one piece with said portions so as to support said inner annular portion with freedom of radial displacement relative to said outer annular portion, said inner annular portion having an inner circumferential surface for receiving and retaining therein a rolling contact bearing, said inner and outer annular portions having respective faces which together bound said gap and which are provided at diametrically opposite locations with sets of concave recesses having open sides facing one another across said gap; a pair of overload protecting pins each received in one of said sets of concave recesses and extending parallel to one another and to a central axis of said member; and means mounted on the web for originating and transmitting signals commensurate with the stressing of said web resulting from the radial displacement of said inner annular portion relative to said outer annular portion.
Claim 3
Dependent Claim
16 words
The unit as defined in claim 1, wherein said inner and said outer portions are rings.
Claim 4
Dependent Claim
17 words
The unit as defined in claim 2, wherein said outer ring is concentric with said inner ring.
Claim 5
Dependent Claim
19 words
The unit as defined in claim 2, wherein said web extends in a substantially radial direction of said rings.
Claim 6
Dependent Claim
18 words
The unit as defined in claim 1, wherein said last mentioned means is an electric last mentioned means.
Claim 7
Dependent Claim
73 words
The unit as defined in claim 1, wherein said portions have an axis and said web has two side portions spaced from one another in a direction substantially transverse to said axis, said last mentioned means including two pairs of strain gauges each mounted on the respective side portion of said web; and further comprising an electrical measuring circuit including a measuring bridge which is formed by said two pairs of strain gauges.
Claim 8
Dependent Claim
137 words
The housing as defined in claim 1, wherein said portions have an axis; further comprising a further such inner portion, outer portion and web axially spaced from said first-mentioned inner portion, outer portion and web, said web and said further web each having two side portions spaced from each other in a direction substantially transverse to said axis, said last mentioned means including two pairs of strain gauges each mounted on the respective one of said webs so that one strain gauge of each pair is mounted on one of said side portions of the respective web whereas the other strain gauge of the same pair is mounted on the other side portion of the same web; and further comprising an electrical measuring circuit including a measuring bridge which is formed by said two pairs of gauges.
