GEAR MEASURING VIBRATION LEVEL OF MACHINES Russian patent published in 2002 - IPC

FIELD: vibration measurement. SUBSTANCE: gear can be employed in mix of hardware used for automatic diagnostics of technical condition of machines. Gear is fitted with metal coupling base. Lower part of base has groove carrying magnetic plate installed inside. Plate is covered by U-shaped lid. Handle of gear is provided with metal lug and vibration damping rubber rings. Forces formed by magnetic field of magnetic plate press coupling base and gear proper against lug of handle forming monolithic structure. Each vibration damping ring has radial shaped groove. Grooves match one another to establish conduit for cable laying. Gear provides for possibility of use of quantity-produced transmitters both for long-term and single-moment measurement of vibration. EFFECT: reduced time of contact of gear with machine thanks to avoidance of necessity of its mounting on machine. 3 cl, 3 dwg
