The invention discloses an oil lubricated radar antenna pedestal, and relates to the field of radar antenna pedestals. The oil lubricated radar antenna pedestal comprises a base, a lubrication cavity,a slewing bearing, a driving gear, a motor reducing gear, a rotary disc and an oil filling port; the base is provided with the lubrication cavity; the slewing bearing and the driving gear are both installed in the lubrication cavity; the slewing bearing is rotationally connected with the base; outer teeth of the driving gear is engaged with outer teeth of the slewing bearing; the motor reducing gear is fixedly connected to the base and drives the driving gear to rotate; the rotary disc is fixedly connected to the slewing bearing; and the lubrication cavity is provided with an oil filling portand an oil discharging port, and a heater is arranged in the lubrication cavity. The oil lubricated radar antenna pedestal has the advantages of being capable of working normally under the low temperature environment and being long in maintenance interval.
Description
technical field [0001] The invention relates to the field of radar antenna bases, in particular to an oil-lubricated radar antenna base. Background technique [0002] The three-coordinate target indication radar has all-weather rapid detection and positioning functions, and has high detection accuracy. For space surveillance in harsh environments such as frontiers, plateaus, and extreme cold, the long-term trouble-free operation of radars puts forward higher requirements for the reliability of the entire radar system. Patent document CN203747016U discloses a multifunctional integrated flat radar antenna base, which includes a vertical direct-connection motor, a driving gear, and a slewing bearing. The gear meshes on the bearing. Existing radar antenna bases have excessive driving torque in low temperature environments, which can easily cause overload to the motor. On the other hand, the existing radar antenna bases have a short lubrication and maintenance cycle, and the lu...
