Embodiment Construction

[0019] Such as figure 1 and figure 2 As shown, a miniaturized electric turntable is mainly composed of a turntable bearing outer pressure plate 2, a turntable 3, a turntable bearing 4, a worm gear box 5, a worm screw 6, a worm gear bearing gland 11, a worm gear shaft 12, a worm gear shaft bearing 13, and a worm gear box Body cover plate 14, harmonic reducer 15, turntable bearing inner pressure plate 16, harmonic reducer mounting bracket 17 constitute.

[0020] The aperture of the input shaft of the harmonic reducer 15 is matched with the worm gear shaft 12. The steel wheel of the harmonic reducer 15 is connected to the mounting bracket 17 of the harmonic reducer with screws, and the mounting bracket 17 of the harmonic reducer is connected to the bracket 1 with screws. The output shaft of wave reducer 15 is connected on the turntable 3 with screws. The worm gear shaft 12 and the worm 6 form a worm drive, the aperture at one end of the worm 6 matches the shaft of the motor 9,...

Abstract

The invention relates to a miniature electrical turntable. The miniature electrical turntable is characterized in that a harmonic reducer is adopted. The miniature electrical turntable is specifically structured as follows: the input shaft hole diameter of the harmonic reducer is matched with a worm-wheel shaft; the output shaft of the harmonic reducer is connected to a turntable through screws; the worm-wheel shaft and a worm form worm drive; the hole diameter at one end of the worm is matched with a motor shaft; a motor is connected to a worm and gear box; the shaft diameter at the two ends of the worm is matched with worm bearings; the worm bearings are matched with the hole diameter of the worm and gear box; a worm shaft bearing press cover is connected to the worm and gear box; the worm and gear box is connected to a worm and gear box cover plate; the worm and gear box cover plate is connected to the turntable through screws; the shaft diameter at the two ends of a worm shaft is matched with worm shaft bearings; the worm shaft bearings are matched with the hole diameter of the worm and gear box; turntable bearings are matched with a harmonic reducer installing support and the turntable; turntable bearing inner press plates are connected to the harmonic reducer installing support through screws; and turntable bearing outer press plates are connected to the turntable through screws.

Description

technical field [0001] The invention belongs to the field of satellite antenna devices, and in particular relates to a miniaturized electric turntable. Background technique [0002] Portable fully automatic satellite antenna refers to a portable satellite antenna that uses mechatronics and signal feedback technology to realize the functions of automatic tracking, automatic locking and automatic storage of satellite antennas. [0003] The electric turntable is an important part of the automatic satellite communication antenna. The motorized turntable should be simple, stable and efficient, especially for small portable antennas. The currently used electric turntable is mainly composed of a turntable, bracket, electrical appliances and other components. This kind of electric turntable has a large shape and is not easy to store the antenna. Moreover, the transmission error between the gears reduces the angular accuracy of the electric turntable. Due to the large size of the tu...
