INSTALLATION FOR INVESTIGATION OF ROTOR SYSTEMS WITH ACTIVE CONTROL Russian patent published in 2020 - IPC G01M13/04 

FIELD: educational laboratory equipment.

SUBSTANCE: invention relates to the field of educational laboratory equipment and can be used in the educational process when conducting laboratory works and practical training in general engineering disciplines in higher and secondary special educational institutions. In an apparatus for examining rotary systems with active control, comprising a housing mounted on a page, fixed in a housing on a shaft connected through a coupling to an electric motor, first bearing assembly, on which a rotation frequency sensor and a pressure sensor are installed, a second bearing unit on which displacement sensors and a pressure sensor are installed, only a temperature sensor and a lubricant level sensor are installed inside the housing, loading device mounted on the shaft and having a force sensor, elements installed in threaded holes of the housing, made in the form of fittings, an electric motor fixed on the base by a bracket, one bearing assembly has a rotation frequency sensor, seals, a lubricating system comprising a tank with lubricant, a pump, a tee connected by means of hydraulic hoses to the tank through series-arranged safety valves and a flow sensor, according to the invention, it additionally includes a unit for control, collection and processing of signals, which inputs are connected to sensors of rotation frequency, temperature, movement, pressure, force, flow rate and level of lubricant, and outputs are with servo-valves, electric motor, pump stations and heating elements placed in tanks with lubricant, one bearing assembly is equipped with conical sliding bearing, lubricating system has three chambers isolated from each other by means of seals to control characteristics of conical friction bearing, to the tanks through hydraulic hoses and filters are connected pump stations, one of which is connected via T-joint to two parallel branches, each of which consists of series-connected safety valve, servo-valve, flow sensor and connected to cavity of bearing assembly with tapered bearing, and other pump station is connected via appropriate hydraulic filter and hydraulic valve to cavity of another bearing assembly, wherein third cavity is connected via hydraulic hoses, element and valve to manifold.

EFFECT: enlarging the area of research of rotor systems due to structural possibility of stand upgrade by means of installation of additional elements in bearing assemblies and possibility of change of lubricant supply circuit in them, as well as possibility of active control of conical bearing unit characteristics.
