Abstract

PURPOSE:To make a motor small in size by driving an antenna at a high speed with meshed 1st gear trains whose gear ratio is small in a rotation enable range and meshing 2nd gear trains whose gear ratio is high to reduce the turning speed of the antenna when the antenna enters a turning limit range. CONSTITUTION:When the antenna traces an artificial satellite or the like, a motor 10 drives a drive shaft 11 in response to a motion of the artificial satellite. The driving torque is delivered to a drive shaft 41 of an antenna 40 via a gear 20 and a tooth locked gear 50 thereby driving the antenna 40 at a high speed in the drive enable range to trace the artificial satellite or the like. When the antenna 40 exceeds the turning enable range and enters a turning limit range, meshing between the gears 20, 50 is released. On the other hand, a gear 30 and a tooth lacked ear 60 mesh with each other and a torque of a motor 400 is delivered to the antenna 40 via the gears 30, 60. Since the gear ratio of the gears 30, 60 is designed large, the speed of the antenna 40 is reduced just after the antenna 40 enters the turning limit range.

In the above-mentioned conventional tracking antenna deceleration device, since tracking in a wide range is possible,
The rotatable range is widened and the limited rotation range is narrowed.
Further, in the rotatable range, it is customary to rotate the antenna at a high speed for tracking artificial satellites and the like. However, in the conventional tracking antenna speed reducer, the motor 102
Since the antenna 101 was always driven with a constant reduction ratio with respect to the rotation of the
The rotation speed of 01 was high even after entering the rotation restriction range. Therefore, the antenna 101 rotating at high speed

Therefore, in the conventional tracking antenna deceleration device, there is a problem that the motor becomes large in size simply to stop the rotation of the antenna.
