Abstract

A device for measuring the temperature of oil in a cylinder block by using a thermocouple. The sealing plug is installed in the center hole of the end surface of the screw head of the screw plug; the thermocouple is installed in the thermocouple installation hole in the center of the screw plug and sealed. The thermocouple mounting hole in the center of the plug. The lead-out terminal of the thermocouple and the temperature measurement working head are distributed outside the two ends of the screw plug. The two ends of the thermocouple are sealed with an adhesive on the end faces of the screw plug and the sealing plug respectively. In the present invention, the thread plug is used as an adapter, an adhesive is used as a connection mode, a thermocouple is fixed on the plug, and the hydraulic interface of the air release nozzle on the cylinder seat of the brake device is used as an insertion point for real-time temperature measurement. The invention has the characteristics of stable performance, convenient use, no maintenance and low manufacturing cost, meets the temperature measurement requirements of the aircraft wheel brake test, and is applicable to the installation and test conditions of -60°C to 200°C and hydraulic oil pressure up to 28MPa.

Description

technical field [0001] The invention relates to temperature measurement of an aircraft wheel brake device, in particular to a device for measuring the oil temperature of a cylinder seat by using a thermocouple. Background technique [0002] During the braking process of the aviation wheel, the huge kinetic energy of the aircraft is converted into heat energy through the mechanical friction of the brake disc. The temperature rises. The cylinder block is a device that provides power for the wheel brakes, and is equipped with multiple hydraulically actuated pistons. After braking, the heat generated by the brake disc is partially transmitted to the cylinder block, which increases the temperature of the cylinder block, and then increases the temperature of the hydraulic oil in the inner cavity of the cylinder block. In order to quantitatively monitor the temperature change of the cylinder seat oil during and after braking, it is necessary to use a temperature measuring device ...
