Embodiment 1

[0022] like Figure 1~4 shown. A device for measuring the oil temperature of a cylinder seat, comprising a thermocouple 1, a screw plug 2 and an adhesive 3. Among them, the thermocouple 1 is installed in the thermocouple installation hole at the center of the screw plug 2, and the lead-out wire end of the thermocouple is located outside the end face of the screw plug, and the temperature measuring head of the thermocouple is located at the other end of the screw plug. One end outside. The two ends of the screw plug 2 are sealed with an adhesive to seal the thermocouple.

[0023] The screw plug 2 is cylindrical. In the center of the screw plug, there is a thermocouple installation hole through longitudinally, which is used to place the thermocouple 1 . The screw plug is divided into a screw plug head section, a screw plug neck section and a screw plug rod section. The screw plug head section of the screw plug is located at one end of the screw plug, and is hexagonal outsid...

Embodiment 2

[0032] The difference between this embodiment and Example 1 is that the seal between the thermocouple 1 and the screw plug 2 is provided with a sealing device rubber sealing ring 4, and the sealing effect is better and more durable.

[0033] like Figure 5-7 shown. This embodiment includes a thermocouple 1 , a screw plug 2 and an adhesive 3 . Among them, the thermocouple 1 is installed in the thermocouple installation hole at the center of the screw plug 2, and the lead-out wire end of the thermocouple is located outside the end face of the screw plug, and the temperature measuring head of the thermocouple is located at the other end of the screw plug. One end outside. The two ends of the screw plug 2 are sealed with an adhesive to seal the thermocouple. Two or one sealing ring 4 is installed in the thermocouple mounting hole of the screw plug.

[0034] The screw plug 2 is cylindrical. In the center of the screw plug, there is a thermocouple installation hole through long...

Abstract

A device for measuring the temperature of oil in a cylinder seat. The thermocouple is installed in the thermocouple installation hole in the center of the screw plug, and the lead-out wire end of the thermocouple is located outside the end face of the screw plug, so that the temperature measurement of the thermocouple The working head is located outside the end surface of the other end of the screw plug. The thermocouple is sealed with the adhesive at both ends of the screw plug. In the present invention, the thread blockage is used as an adapter, an adhesive is used as a connection mode, a thermocouple is fixed on the blockage, and a hydraulic interface of an air release nozzle on a cylinder block of a brake device is used as an insertion point for real-time temperature measurement. The invention has the characteristics of stable performance, convenient use, no need for maintenance and low manufacturing cost. After many times of bench brake tests, there is no looseness and oil leakage, and it can accurately and reliably measure and indicate the temperature of the measured medium, which meets the requirements of aircraft wheel brakes. Test temperature measurement requirements; high and low temperature resistance, high pressure and vibration, applicable to installation test conditions of -60°C ~ 200°C, 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 powers 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 or instrument...
