Abstract

The invention relates to a novel oil bath rotary table. The novel oil bath rotary table comprises a rotary table outer shell (4), a rotary table outer cover (1), an upper main shaft (7), a lower main shaft (8) and a direction speed reducer (2). An oil tank (12) is arranged on the upper portion of the rotary table outer shell (4), an annular step groove (16) is formed in the outer wall of the oil tank (12), a bearing (5) is installed in the annular step groove (16), the lower main shaft (8) is installed in an inner ring of the bearing (5), the lower end face of the rotary table outer cover (1) is fixedly connected with the upper end face of the rotary table outer shell (4), at least one door (9) is formed in the outer wall of the rotary table outer cover (1), the direction speed reducer (2) is vertically installed on a direction speed reducer installation face (17), a power gear (6) at the output end of the direction speed reducer (2) is meshed with an inner ring gear of the bearing (5), and a direction transmitter (3) is further arranged at the bottom of the rotary table outer shell (4). The novel oil bath rotary table has the advantages that the rotary table does not leak oil, the maintenance is convenient, and the service life is long.

Description

technical field [0001] The invention relates to an antenna turntable, in particular to a novel oil bath turntable. Background technique [0002] Antenna is an essential part of wireless transmission equipment, used to receive and send wireless communication signals. Most of the current antennas are fixed on the supporting frame, and transmit wireless communication signals in an omnidirectional or directional manner. Omni-directional antenna brackets need to be equipped with turntables. The existing oil-bath turntables have a high failure rate, which reduces the reliability and continuity of long-term operation of the antenna turntable and increases the maintenance cost of the antenna turntable. The main reason for this phenomenon is that the azimuth reducer and azimuth transmitter are installed upside down, the meshing of the output gear (final stage) and the power gear is in the fuel tank, and the installation surface is attached to the lower end surface of the fuel tank ...
