Abstract
Abstract Apparatus for designing and determining parameters for supporting hydrodynamically lubricated bearing journals, wherein a device for applying a load to a shaft is associated with a shaft mounted on bushings carried by ball joints, the shaft and bushings being electrically insulated from the remainder of the apparatus, and detecting devices being also provided which are responsive at determined locations to changes in parameters, such as supporting pressure, temperature, separation between shafts and bushings, and the like.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
An apparatus for designing and testing the proper values of parameters relating to supporting hydrodynamically lubricated bearing journals, comprising: a base; two independent bushings mounted on said base; a shaft mounted in said bushings; a device coupled to said shaft between said bushings for load application to said shaft, said shaft and bushings being electrically insulated from the remainder of the apparatus; ball joints and bearings rockably mounting said bushings for self-alignment with said shaft; and at least one detecting device associated with each of the bushings and said shaft, said detecting device being adapted to indicate the value of a selected parameter.
Claim 2
Independent Claim
103 words
An apparatus for designing and testing the proper values of parameters relating to supporting hydrodynamically lubricated bearing journals, comprising: a base; two independent bushings mounted on said base; a shaft mounted in said bushings; a device coupled to said shaft between said bushings for load application to said shaft, said shaft and bushings being electrically insulated from the remainder of the apparatus; ball joints and bearings rockably mounting said bushings for self-alignment with said shaft; and at least one detecting device associated with each of the bushings and said shaft, said detecting device being adapted to indicate the value of a selected parameter.
Claim 3
Dependent Claim
43 words
An apparatus according to claim 1, wherein said detecting location for the supporting pressure comprises a hole which is properly proportioned and positioned within the bushing and communicating with a channel leading to a pressure gauge, with detection capability even during shaft rotation.
Claim 4
Dependent Claim
64 words
An apparatus according to claim 1, wherein said shaft includes a brush commutator, and said device for detecting separation between the shaft and bushing includes, for each of the bushings, a pilot lamp provided with an ammeter and connected to the bushing and negative pole of a battery, of which the positive pole is connected to said brush commutator associated with said rotating shaft.
Claim 5
Dependent Claim
48 words
An apparatus according to claim 1, wherein said device for load application to the rotating shaft comprises: a bearing about said shaft; a pressure member bearing on said bearing; and a hydraulic cylinder acting on said pressure member carried on said shaft through the interposition of said bearing.
Claim 6
Dependent Claim
20 words
An apparatus according to claim 1, wherein said detecting device is responsive to separation between said shaft and said bushing.
Claim 7
Dependent Claim
18 words
An apparatus according to claim 1, wherein said detecting device is responsive to the temperature at the bushing.
Claim 8
Dependent Claim
25 words
An apparatus according to claim 1, wherein said detecting device is responsive to the supporting pressure of said bushing at determined locations along said bushing.
