Abstract
The utility model provides a satellite antenna elevation transmission device. By powering a step motor or manually rotating a lifting hand wheel, an elevation long shaft and an elevation short shaft are driven to rotate. Speed reduction of a harmonic gear speed reducer assembly and flexible wheel output are carried out. Through an elevation flexible wheel connecting plate, a gas spring fixing plate, a support arm and an elevation ladder sleeve, the elevation movement of a paraboloid antenna array is realized. When the paraboloid antenna array moves to a predetermined angle, the paraboloid antenna array moves downward under the action of gravity due to the fact that the harmonic gear transmission does not have a self-locking function. At the moment, an elastic hand wheel is rotated to enable the end face to closely contact the end face of the elevation ladder sleeve. Certain friction is produced, so that locking of the antenna elevation movement is realized. According to the device, the harmonic gear transmission assembly is used, so that the antenna elevation transmission device has advantages of small volume, light weight and large transmission; simply through single stage transmission, the requirement of transmission ratio can be met; and the device is especially suitable for a portable satellite antenna structure form which can be carried around and is used for real time rebroadcast.
