Lubricating oil chip monitoring and alarming annunciator

Abstract

The invention provides a lubricating oil chip monitoring and alarming annunciator which comprises an annunciator assembly, a check ring, a wave spring, a shell and an oil drainage valve, a cavity is formed in the shell, a lubricating oil inlet and a lubricating oil outlet are formed in the upper side and the side edge of the shell respectively, the shell is provided with an oil drainage opening, and the oil drainage valve is installed in the oil drainage opening; the annunciator assembly is limited in a cavity of the shell through a check ring and a wave spring, the annunciator assembly comprises a plurality of conductive gaskets, an end cover assembly, a nut, an outer sleeve, a lantern ring, an electric socket with a plurality of contact pins and a metal rod, and the metal rod is arranged in the cavity of the shell in the axis direction of the lubricating oil outlet. The lantern ring and the end cover assembly are distributed on the two axial sides of the metal rod, a plurality of conductive gaskets are arranged between the lantern ring and the end cover assembly, the insulating outer sleeve is arranged between the end cover assembly and the lantern ring, part of the contact pins are connected to the lantern ring, and the other part of the contact pins are connected to the metal rod. And when the metal chips are gradually accumulated at the conductive gasket to fill the gap, the lantern ring and the end cover assembly are conducted with the metal rod to form an access.

Description

technical field [0001] The application relates to the technical field of signal alarm devices, in particular to an alarm signal device for monitoring the end of lubricating oil chips. Background technique [0002] In aero-engines, due to the high temperature, high speed, and high load of the bearing, lubricating oil is usually used to lubricate and cool the bearing. During the working process, the lubricating oil may take away the metal debris generated during the operation of the mechanism, but the metal debris will pose a safety hazard to the use of the bearing. Therefore, the monitoring technology of lubricating oil scraps is often used to quickly and accurately reflect the wear of the bearing and the transmission mechanism, and alarm when serious, so as to avoid further damage to the bearing and the transmission mechanism, and prevent the occurrence of engine failure. [0003] like figure 1 Shown is a typical lubricating oil dust monitoring and alarming annunciator. Th...
