Antenna tilt balancing part, balancing bracket and balancing mechanism containing antenna tilt balancing part

Abstract

The invention belongs to antenna tilt balancing parts, and particularly relates to an antenna tilt balancing part, a balancing bracket and a balancing mechanism containing the antenna tilt balancing part. The balancing mechanism includes the U-shaped balancing bracket, and the antenna tilt balancing part is arranged on the balancing bracket; the antenna tilt balancing part includes a shell, an anti-torque spring, an anti-torque shaft and a bearing, the outer ring of the bearing is fixedly connected with the inner wall of the shell, one end portion of the anti-torque shaft penetrates through the inner ring of the bearing and is connected with the other end of the anti-torque spring, and the other end portion of the anti-torque shaft extends to the exterior of the shell. Through adoption ofa tilt balancing device, eccentric torque generated on the anti-torque shaft by the surface of an antenna under the gravity effect can be overcome, stress performed on the surface of the antenna is balanced, the loaded torque of a motor is reduced, and therefore a tilt motor on the surface of the antenna can drive the surface of the antenna to rotate around a tilt axis under low power to achieve required speed and accelerated speed, so that required accuracy is achieved, not only is the cost saved, but also the weight and size of the overall machine are reduced, and the demands of design and application can be met.

Description

technical field [0001] The invention belongs to the technical field of satellite antennas, and in particular relates to an antenna pitch trim member, a trim bracket and a trim mechanism including the antenna pitch trim member. Background technique [0002] In order to track targets in real time, ship-mounted, vehicle-mounted or airborne antennas are generally designed with azimuth axes, pitch axes, and polarization axes, and the movement of each axis is driven by a motor. The parameters of the load torque directly determine the selection of the motor power, and at the same time determine the volume and weight of the motor, which in turn affects the volume and weight of the antenna. The azimuth axis is usually supported by a horizontal support mechanism, and the eccentric mass acting on the azimuth axis will not be very large. However, for the pitch axis, due to factors such as the antenna support structure and the antenna envelope size limitation, the pitch support is desig...

Problems solved by technology

[0003] In order to solve the problems existing in the prior art of increasing the weight and volume of the motor, increasing the power consumption, increasing the cost, and complicating the structure, the present invention provides an antenna pitch trim piece, a trim bracket, and a trimming device containing the antenna pitch trim piece. The mechanism can overcome the eccentricity of the antenna surface, and then balance the force on the antenna surface, reduce the load torque of the motor, not only save the cost, but also reduce the weight and volume of the motor, which can meet the needs of design and application
