Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
Apparatus for testing rotary power-transmitting components or transmission trains having separate, mechanically coupled, rotatable, input and output means comprising; a means of rotating the input means of the component being tested, an angular accelerometer driven from the input means of the components, or transmission trains an angular accelerometer driven from the output means of the components, or transmission trains a means for combining the electrical outputs of the accelerometers so that the outputs add for accelerations caused by the components or transmission trains being tested, and a means for displaying or utilizing the combined electrical outputs of the accelerometers.
Claim 2
Dependent Claim
99 words
Apparatus for testing rotary power-transmitting components or transmission trains having separate, mechanically coupled, rotatable, input and output means comprising; a means of rotating the input means of the component being tested, an angular accelerometer driven from the input means of the components, or transmission trains an angular accelerometer driven from the output means of the components, or transmission trains a means for combining the electrical outputs of the accelerometers so that the outputs add for accelerations caused by the components or transmission trains being tested, and a means for displaying or utilizing the combined electrical outputs of the accelerometers.
Claim 3
Dependent Claim
43 words
Apparatus as described in claim 1 with supports on which the input and output means of the components to be tested are mounted, with means for adjusting the supports so as to obtain a desired physical relation between the input and output means.
Claim 4
Dependent Claim
21 words
Apparatus as described in claim 1 with the addition of a means for adjusting the effective sensitivities of the accelerometers individually.
Claim 5
Dependent Claim
30 words
Apparatus as described in claim 1 with the addition of a means for filtering out of undesired frequencies either in the individual accelerometer outputs or in the combined accelerometer outputs.
Claim 6
Dependent Claim
25 words
Apparatus as described in claim 1 with the addition of a means for applying a torque load on the component or transmission train being tested.
