Specialists from the Military Academy named after Army General A.V. Khrulev developed a device for rapid diagnostics of the electric-machine gun stopper of the T-72B3 tank gun. The utility model makes it possible to check the condition of the limit switches and the operability of the autoloader motor without disassembling the unit.
The device connects directly to the standard connector of the stopper electric motor. This makes it possible to carry out the check without removing the contact block, access to which is difficult during field maintenance.
The T-72B3 autoloader operates according to a rigidly predefined algorithm. Any failure in the signals from sensors or switches leads to the cycle stopping. One of the most frequent causes of failures remains the wear of the K1, K2, and K3 microswitches built into the gun stopper gearbox.
The new device makes it possible to determine their condition in a few minutes. The design uses a circuit with light indication. Separate lamps signal the actuation of each switch and the power supply. Additionally, a test mode for the M6 electric motor is provided.
For operation, it is enough to connect the cable to the stopper connector and the onboard power source. After switching on, the operator receives information from the indicator readings about the condition of the contacts and the gun locking mechanism. If a malfunction is detected, the unit is subject to replacement without a lengthy search for the cause of the failure.
