FIELD: transport.
SUBSTANCE: invention relates to railway transport, particularly to heat diagnostics of rolling stock running gear parts with the help of thermistor receivers of IR receivers, that is, bolometers. Thermistor bolometer with immersion germanium lens is arranged in case with circular spherical surface. Bolometer attachment fitting body is arranged in mating ball surface of thermal barrel and locked by yoke. Bolometer optimum temperature is maintained by heaters built in thermal barrel grooves. Bolometer temperature gage is secured opposite the thermal barrel heaters. To trap out dust and moisture sleeve with circular crosswise baffles is fitted in thermal barrel upstream of bolometer. Flap with radiators to simulate the box is composed of turn sector is secured directly at step motor shaft mounted at chamber baffle. Chamber front cover in inlet zone accommodates adapter with heating elements, sleeve with transverse ribs and thermal barrel sleeve.
EFFECT: higher reliability, decreased electric power consumption.
