Abstract

The invention discloses a rotary table mechanical limiting mechanism and method with configurable limit rotation angle. The mechanism comprises a limited gear fixed with a rotary table, and the angleof the rotary table can be adjusted and controlled by adjusting the angle of the limited gear; the angle adjustment of the limited gear is realized by a mechanical limiting device, the structure of the mechanical limiting device comprises an input gear, a screw rod shaft and an adjusting device, wherein the input gear is fixed on a lead screw shaft, the adjusting device adjusts the limit rotationangle of the screw rod shaft, and the adjustment of the limit rotation angle of the rotary table is realized through the transmission of the input gear and the limited gear. By adopting a pure mechanical limiting mode, the rotary table mechanical limiting mechanism with configurable limit rotation angle is proposed, the mechanical limiting angle of the rotary table can be configured in real time under different working conditions without the assistance of any electrical control device, and the application range is wider.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a turntable mechanical limit mechanism and method with configurable rotation angles, which are used for mechanically limiting the rotation limit position of the turntable and protecting the turntable and the connecting cables of electronic equipment on the turntable. Background technique [0002] In radar and electronic warfare equipment, it is necessary for the turntable to carry the antenna feeder system and other equipment to rotate, so as to realize the search and tracking of the target signal. The antenna feeder system connects the radio frequency cable with the fixed equipment through the turntable, and it is difficult to realize multi-channel, low dropout and continuous transmission of radio frequency signals through devices such as confluence rings. Therefore, most turntables use reciprocating rotation within a certain range to realize antenna feed...
