Abstract
Abstract A pickup for measuring vibration parameters of operating machinery parts includes a housing shaped as a truncated cone and inserted into a collet having a conical internal surface which conjugates with the tapered surface of the housing, the outer surface of the collet being cylindrical and threaded. Built into the pickup housing is a sensitive element whose sensitive axis extends along the axis of rotation of the housing or is perpendicular to the axis of rotation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
57 words
A pickup for measuring vibration parameters of operating machinery parts, comprising: a housing shaped as a truncated cone; a collet into which the housing is inserted; the collet having a conical internal surface conjugated with the conical surface of the housing; the collet having a cylindrical threaded external surface; and a sensitive element built into the housing.
Claim 2
Dependent Claim
57 words
A pickup for measuring vibration parameters of operating machinery parts, comprising: a housing shaped as a truncated cone; a collet into which the housing is inserted; the collet having a conical internal surface conjugated with the conical surface of the housing; the collet having a cylindrical threaded external surface; and a sensitive element built into the housing.
Claim 3
Dependent Claim
99 words
The pickup for measuring vibration parameters of operating machinery parts as claimed in claim 1, wherein the sensitive element is arranged so that its sensitive axis is generally perpendicular to a rotational axis of the housing; and further comprising: a cylindrical projection on the outer end face surface of the housing; a notch provided on the projection to turn the housing about its axis of rotation; and a hole in the bottom of the collet, the diameter of the hole being larger than the diameter of the projection, the hole being intended to provide access to the notched projection.
Claim 4
Dependent Claim
92 words
The pickup for measuring vibration parameters of operating machinery parts as claimed in claim 1, wherein the sensitive element is arranged so that its sensitive axis extends along a rotational axis of the housing; and further comprising: a cylindrical projection having a threaded external surface on the outer end face surface of the housing; a hole in the bottom of the collet, the diameter of the hole being larger than the diameter of the projection; and a lock nut adapted to be screwed on the threaded external surface of the cylindrical projection.
Claim 5
Dependent Claim
43 words
The pickup for measuring vibration parameters of operating machinery parts as claimed in claim 2, wherein the cylindrical projection has a threaded external surface; and further comprising a lock nut adapted to be screwed on the threaded external surface of the cylindrical projection.
