Abstract
Abstract A measuring apparatus for measuring forces acting upon a bearing, particularly the radial forces, effective at a roller bearing. The measuring apparatus essentially comprises two rings, typically formed of metal, which are concentrically interconnected by means of a web. The roller bearing transmits the force to be measured to one of the rings, whereas the other ring is fixed. The one ring rocks or moves in relation to the fixed ring and the deformation prevailing at the web is electrically measured and indicated in a display or indicator device. The measuring apparatus serves for measuring the tension in belts, bands, and the like.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
57 words
An apparatus for measuring the forces, particularly the radial forces acting upon a bearing, especially a roller bearing, comprising: two concentric ring members interconnected by web means; said web means constituting an elastically deformable element which deforms in the presence of a force which is to be measured and is capable of influencing an electric signal transmitter;
Claim 2
Independent Claim
57 words
An apparatus for measuring the forces, particularly the radial forces acting upon a bearing, especially a roller bearing, comprising: two concentric ring members interconnected by web means; said web means constituting an elastically deformable element which deforms in the presence of a force which is to be measured and is capable of influencing an electric signal transmitter;
Claim 3
Dependent Claim
83 words
the inner one of said ring members being equipped with attachment means, for the fixation thereof, and the outer one of said ring members being structured for receiving the bearing so that said outer ring member, in the presence of the force which is to be measured, is capable of carrying out a pivotal movement with respect to said inner ring member, said attachment means comprising an attachment plug means which axially protrudes from at least one face of the inner ring member.
Claim 4
Dependent Claim
83 words
the inner one of said ring members being equipped with attachment means, for the fixation thereof, and the outer one of said ring members being structured for receiving the bearing so that said outer ring member, in the presence of the force which is to be measured, is capable of carrying out a pivotal movement with respect to said inner ring member, said attachment means comprising an attachment plug means which axially protrudes from at least one face of the inner ring member.
Claim 5
Dependent Claim
47 words
The measuring apparatus as defined in claim 1, wherein: said bearing constitutes a roller bearing having an inner race seated upon the outer circumference of the outer ring member; and said roller bearing having an outer race carrying an element for transmitting the force to be measured.
Claim 6
Dependent Claim
24 words
The measuring apparatus as defined in claim 1, wherein: said attachment plug means possesses an axial bore for the throughpassage of a measuring cable.
Claim 7
Dependent Claim
23 words
The measuring apparatus as defined in claim 1, wherein: both of said ring members and said attachment plug means are formed of one-piece.
Claim 8
Dependent Claim
20 words
The measuring apparatus as defined in claim 1, wherein: said attachment plug means is pressed into said inner ring member.
Claim 9
Dependent Claim
21 words
The measuring apparatus as defined in claim 1, wherein: both of said ring members are arranged in a common housing means.
