Technical Field

The invention belongs to the technical field of artillery balancing, and particularly relates to a finite space artillery balancing device.

Background

Because the installation and the motion space of the tail part of the artillery given by the structural form of the tower bodies of the artillery of some war chariot are limited, the artillery is heavy in front and light in back, huge unbalanced moment is generated relative to the rotating shaft center, the size of the motor is increased due to the fact that more high power is consumed during pitching driving of the artillery, and difficulty is increased for dynamic accurate control of pitching of the artillery.

According to the use requirement of weapons, under the condition that the size of the turret is clearly limited, the pitching motion cannot be realized due to interference of the turret tail with the counterweight block due to narrow space. Therefore, how to realize the dynamic balance of the pitching of the artillery in a narrow space becomes a problem which needs to be solved urgently.

Disclosure of Invention

In view of the above, the present invention provides a finite space artillery balancing device, which can dynamically balance the artillery relative to the rotation center within a certain angle range under the condition of finite space, so that a servo system can dynamically and accurately control the pitching angle of the artillery, and improve the shooting hit rate.

The invention is realized by the following technical scheme:

a finite space artillery balancing device comprising: the device comprises a balancing weight, a trunnion resolver, a trunnion extension block, a bearing, a tooth arc plate, a transmission part and a servo system;

the artillery to be trimmed is arranged on the artillery cradle through the trunnion; the artillery is fixedly connected or connected with the trunnion, namely the artillery and the trunnion rotate synchronously; the artillery cradle is fixed on an external supporting platform, and the artillery and the trunnion can rotate around the axis of the trunnion;

the trunnion resolver is arranged outside the trunnion and used for acquiring the pitching angle data of the artillery in real time and sending the data to the servo system;

the trunnion extension block is coaxially fixed at one end of the trunnion;

one end of the balancing weight is coaxially arranged on the trunnion extension block through a bearing, and the balancing weight can rotate relative to the axis of the trunnion extension block;

the tooth arc plate is fixed on the balancing weight, a tooth arc is processed on the tooth arc plate, and the tooth arc is coaxial with the trunnion extension block;

the transmission part is arranged on the tail part of the artillery, and the transmission part is matched with the tooth arc and used for driving the transmission part and the balancing weight to move relatively.

Further, the balancing weight and the artillery cradle keep a relative static state.

Further, the transmission part is installed on the tail part of the artillery through an installation plate.

Further, the transmission portion includes: the output gear, the motor and the transmission case;

the motor is arranged on the mounting plate, an output shaft of the motor is coaxially connected with an input end of the transmission case, and an output end of the transmission case is coaxially connected with the output gear; the output gear is meshed with the tooth arcs of the tooth arc plates; when the gun pitching control system works, the servo system controls the motor to work according to the pitching angle of the gun, and the motor drives the output gear to rotate through the transmission case.

Furthermore, the output end of the transmission case is coaxially connected with the output gear through a safety clutch.

Furthermore, the transmission case adopts worm and gear transmission.

Has the advantages that: (1) the invention adopts an electromechanical compound mode to carry out artillery balancing, and the transmission part drives the balancing weight to realize controllable motion, so that the balancing weight can be stabilized in a fixed space and does not interfere with a tower body no matter the artillery is in a static state or a motion state, and the artillery is always kept in a balanced state; according to the angle of the real-time every single move of the artillery, the transmission part drives the balancing weight to rotate in the same angle relative to the artillery in the reverse direction by taking the trunnion as the axis, so that the balancing weight is static relative to the artillery cradle, and then under the condition that the space in the artillery tower at the tail of the artillery is limited, the balancing weight cannot interfere with the tower body.

(2) The balancing of the artillery is realized by adding the balancing weight, so that the balance of the artillery under a static state can be realized, and a balance state can be still maintained under the condition that the artillery is dynamically accelerated; according to artillery every single move state adjustment counter weight position promptly, make counter weight and tower body not take place the balance of artillery relative rotation axle center under the condition of interfering, the balancing weight passes through transmission part, is used for the weight at the artillery afterbody all the time, makes the artillery that is in before heavy back light use the trunnion to reach the balance as the axle center, and the unbalanced moment that has significantly reduced when reducing artillery drive power, does benefit to the dynamic every single move angle of accurate control artillery more, improves artillery shooting accuracy.

(3) The safety clutch is arranged between the gear box and the output gear of the transmission part, so that even if the balancing weight and the tower body are interfered, the safety clutch can slip due to overlarge resistance, the tower body cannot be damaged greatly, and the safety of the tower is improved.

(4) The transmission case adopts worm and gear transmission, not only realizes large transmission ratio, but also has the characteristic of incapability of reverse transmission; when the artillery is in a power-on state and is static, the counterweight block is stable at a certain position, the motor can be driven for a pause, and overheating and even damage of the motor due to long-term rotation blockage are avoided; when the artillery is in a power-off state, the counter weight block can be always stabilized at a certain position because reverse transmission cannot be carried out, and the counter weight block does not need to be independently powered up and driven.
