2. Description of the Related Art A motor is used as a drive source in a drive mechanism of a cam drum for driving a play bottom, which has been conventionally used. Further, since the rotation speed of the cam drum needs to be changed depending on, for example, the firing speed of the machine gun, a speed change mechanism is incorporated between the motor and the cam drum. As a method of changing the rotation speed of the cam drum, there is a method of changing the rotation speed of the motor, but it is hardly used because it is inefficient and the control unit is expensive.
Further, in the case of having a mechanical speed change mechanism, the rotation speed of the motor that is the power source is substantially constant, and therefore the output torque is also constant. Further, the drive torque required by the motor is composed of friction torque of the drive mechanism and the like, basic torque consisting of drive mechanism drive torque, and play bottom acceleration / deceleration torque required for acceleration and deceleration of the play bottom. Among these, the friction torque and the feed mechanism driving torque show substantially constant values, but the play torque driving torque varies. That is, for example, in the case of a machine gun, the breech bolt moves forward-
Repeat the stop-back-stop cycle. Therefore, the cam drum which drives the play bottom requires an acceleration torque to accelerate the play bottom when the play bottom is moved forward or backward from the stop. On the other hand, when the play bottom stops from the forward or backward movement, the cam drum receives a rotational force from the play bottom. For the above reasons, the torque required to drive the cam drum fluctuates, and the motor is selected according to the required maximum torque.

In the drive mechanism of the playground driving cam drum according to the present invention, when the motor is rotated, the cam drum is rotated via the gear, the speed change mechanism and the non-circular gear. Each of the non-circular gears has a maximum reduction ratio at the rotation angle of the cam drum at the maximum acceleration torque when accelerating the free bottom for forward or backward movement, that is, the motor output torque is maximized and transmitted to the cam drum. Even if the output torque of the motor is constant, the torque that drives the cam drum fluctuates and becomes maximum when necessary, and the speed is increased when other required drive torque is small to drive the cam drum. The torque becomes smaller. Therefore, although the output torque of the motor is constant, the cam drum can be driven with varying torque via the non-circular gear.

It is combined so that it may be transmitted to 7. Therefore, even if the output torque of the motor 15 is constant, the torque for driving the cam drum 7 fluctuates and reaches its maximum, and the speed is increased when other necessary driving torque is small, and the torque for driving the cam drum 7 becomes small. . Therefore, although the output torque of the motor 15 is constant, the non-circular gears 16 and 17 are

Since the driving mechanism of the cam drum for driving the play bottom according to the present invention is configured as described above, the following effects can be obtained. That is, as shown in FIGS. 4 and 5, by appropriately selecting the value of ε of the non-circular gear in consideration of the breech bolt acceleration torque T V necessary for accelerating the breech bolt, even if the output torque of the motor is constant, the cam motor Drive torque can be increased. Therefore, the output torque of the conventional motor satisfying the basic torque T B + the play bottom acceleration torque T V can be replaced with a motor having a configuration in which only the output torque of the basic torque T B is considered. The motor can be downsized and the power consumption can be significantly reduced. Further, since the motor, which is the drive source, can be downsized, the weight of the entire device can be reduced, and the transportation can be facilitated.
