Abstract

A lubricant deterioration sensor, which is installed in a machine and detects deterioration of lubricant of the machine, is provided. A gap forming member forming an oil gap in which the lubricant enters, is provided. A supporting member, which supports a light emitting element, a color light reception element and the gap forming member, is provided. A fixing member to be fixed to the machine is provided. The gap forming member transmits light emitted from the light emitting element. The oil gap is disposed on an optical path from the light emitting element to the color light reception element. The fixing member supports the supporting member so as to be rotatable so that the direction of the opening of the oil gap changes when the supporting member rotates.

Description

technical field [0001] The present invention relates to a lubricating oil deterioration sensor for detecting deterioration of lubricating oil of a machine. Background technique [0002] Conventionally, as a lubricating oil deterioration sensor, an oil deterioration degree sensor is known in which an oil entry device for entry of lubricating oil is formed on an optical path from an infrared LED (Light Emitting Diode (light emitting diode)) to a photodiode. gap portion, and measure the light absorption amount of the lubricating oil in the oil entry gap portion with respect to the light emitted from the infrared LED from the light reception amount of the photodiode to thereby determine the lubricating oil related to the light absorption amount thus measured degree of deterioration (for example, see Patent Document 1 and Patent Document 2). [0003] However, the oil deterioration degree sensor described in each of Patent Document 1 and Patent Document 2 has the problem that alt...
