Problems solved by technology

[0003] 1. The locking structure of the motor is a frictional locking structure. Therefore, when the rotation is stopped, the rotating frame will gradually stop rotating due to the friction force. However, because the speed of each rotating frame is different, it is necessary for the rotating frame to stop rotating. It is difficult to precisely control the rotation angle when
[0004] 2. When a motor drives the slewing frame to rotate, the motor is affected by the current, and the speed fluctuates greatly, resulting in a large fluctuation in the speed of the slewing frame, resulting in the instability of the entire conduction system, and it is easy to make the slewing frame driven by a motor The slewing frame shakes, which affects the stability

Abstract

The invention discloses a rotary inertial navigation driving and locking integrated device and a using method thereof. The rotary inertial navigation driving and locking integrated device comprises aworm wheel; a first worm is meshed with the left side of the worm wheel, and a second worm is meshed with the right side; the first worm and the second worm are respectively connected with a first rotating device and a second rotating device; and the worm wheel is fixedly connected with a rotary frame. The device is simple in structure and convenient to use, rotation and locking of the rotary frame are controlled through the two motors, the rotary frame is made to operate stably, locking is rapid and accurate, and the rotary frame can accurately stop at the needed angle.

Description

technical field [0001] The invention belongs to the field of navigation, and in particular relates to a rotary inertial navigation drive and locking integrated device and a use method thereof. Background technique [0002] Inertial navigation is a kind of navigation device commonly used in aircraft, missiles and other aircraft. Inertial navigation requires the use of a rotatable slewing frame, and the existing slewing frame usually uses a motor to drive the rotation or locks with the locking structure of the motor when it stops. However, it is prone to the following problems: [0003] 1. The locking structure of the motor is a frictional locking structure. Therefore, when the rotation is stopped, the rotating frame will gradually stop rotating due to the friction force. However, because the speed of each rotating frame is different, it is necessary for the rotating frame to stop rotating. It is difficult to control the rotation angle precisely. [0004] 2. When a motor dr...
