Roll support transmission structure

Abstract

The invention discloses a roll support transmission structure comprising a roll group weld assembly, wherein the roll group weld assembly comprises a support base and a support column fixedly connected with the support base; the tail end of the support column away from the support base are fixedly connected with a roll bearing base 1 and a roll bearing base 2 which are disposed opposite to each other; a speed reducer is disposed on the inner wall of an end of the support column away from the support base; the input shaft of the speed reducer successively extends out of the support column and the roll bearing base 1 and then is connected to the output shaft of a driving motor; the driving motor is fixedly connected with the roll bearing base 1; the output shaft of the speed reducer successively extends out of the support column and the roll bearing base 2 and then is sleeved with a belt pulley at its tail end; the belt pulley 1 is in driving connection with a belt pulley 2 through a synchronous belt; the belt pulley 2 sleeves the end portion of the a roll shaft; the roll bearing base 2 is provided with a belt pulley tensioning device; and the two ends of the roll shaft are arrangedon the roll bearing base 1 and the roll bearing base 2 through bearings respectively. The roll support transmission structure has a good support capability, saves processes and space, and is light andreliable, silent and stable.

Description

technical field [0001] The invention belongs to the technical field of structural design of shipborne antennas, and in particular relates to a rolling support transmission structure. Background technique [0002] The antenna is a kind of converter, which converts the guided wave propagating on the transmission line into the electromagnetic wave propagating in the unbounded medium, or performs the opposite transformation. Most of the turntables of the current ship-borne antenna are driven by gears, which have high noise and are easy to wear and tear. Rusty, and the rolling components are mostly machined and assembled from aluminum plates, which are relatively heavy and take up a lot of space. The processing cost of materials is high, and the assembly is time-consuming and laborious, and the surface finish is easy to be damaged during assembly and debugging. Contents of the invention [0003] In view of this, the present invention provides a rolling support transmission stru...
