The provision in the basis for parabolic antenna

摘要

The provision in the basis for satellite dish, essentially, the basis for the antenna consists of a mechanical structure to support the antenna parable leaked preferably four meters in diameter of 360 degrees in azimuth tracking and 180 degrees in elevation in this parable.The mechanical components such as shafts, gears, pinions, and bearings are subjected to electrolytic treatment and chromate passivation; while structural components, such as the cradle (4) and a set of basis of the parable are produced in the templates. The parable itself (P) has a The central axis of elevation (5) mounted on a base (6) of the parabola.It includes two parallel discs (7) and a crosspiece (8) supported in prismatic clamps (9), and that in this set is the axis (10), which is based on extreme bearings (11) positioned on the cradle (4), so that said axle (10) is connected to the gear like a half moon (3); the set f Ormado by cradle (4) and the other elements described above, it is based on a 360 degrees (2),This coupled in the shaft (13) and configuring helical teeth (14) in all border; on the posterior part of the external metal tower (16) is arranged a set reducer motor (19) which receives the pinion gear (15) of the gear coupling and 360 degrees; (2) in the central part I. Nterna cradle (4) is a second set reducer motor (20) which promotes the drive gear180 degrees elevation of the parable (P); the counterweights (21) are designed to be coupled to the axle (10), so that each said counterweight (21) has an inclination of 10 degrees.
