Furthermore, a support sleeve is arranged between the disc spring and the baffle plate.

The utility model has the advantages that:

1. the artillery turnover mechanism and the buffer mechanism are combined into a whole, so that the artillery turnover mechanism occupies a smaller space, is lighter in weight and reduces redundant weight. The light weight of the four-foot type big frame structure of the light artillery is realized;

2. the lighter gun turnover mechanism has the advantages that the lighter gun turnover mechanism is satisfied, the stress of the gun turnover mechanism is reduced, and the service life and the stability of the gun turnover mechanism are improved.

Drawings

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Fig. 1 is a schematic structural view of the utility model mounted on a big gun frame.

Fig. 2 is a schematic structural diagram of the present invention.

Reference numbers in the figures:

1. the device comprises a rear big frame, 2, a driving mechanism, 3, a cannon lower frame, 4, a shell, 5, a top cover, 6, an outer shaft baffle, 7, a bearing, 8, an inner shaft baffle, 9, a disc spring, 10, a baffle, 11, a worm, 12, a support sleeve, 13 and a worm wheel.

Detailed Description

As shown in fig. 1-2, a driving mechanism of a light artillery rear big frame comprises a rear big frame 1, a driving mechanism 2 and an artillery lower frame 3, wherein the driving mechanism 2 is installed on the artillery lower frame 3 and is driven by a main shaft to rotate with a rotating shaft fixed on the rear big frame 1, the rear big frame 1 is hinged with the artillery lower frame 3 through the rotating shaft, the driving mechanism 2 consists of a worm gear mechanism, a disc spring 9 for buffering stress between the worm gear and the worm is arranged on a shaft rod of a worm 11 in the driving mechanism, the worm 11 is rotated to drive a worm wheel 13 to rotate, so that the rear big frame 1 is turned over, and meanwhile, the worm gear mechanism can realize self-locking, so that a frame body keeps a fixed posture. When the artillery shoots, the rotating shaft is meshed with the worm 11 through the worm wheel 13 and swings back and forth, the worm 11 is buffered with the worm wheel 13 through the disc spring 9, and the stress of the frame body is relieved.

Furthermore, the driving mechanism consists of a shell 4, a top cover 5, an outer shaft baffle 6, a bearing 7, an inner shaft baffle 8, a disc spring 9, a baffle 10, a worm 11 and a worm wheel 13, wherein the worm wheel 13 is sleeved on a rotating shaft of the rear big frame 1, the worm 11 is in tooth meshing with the worm wheel 13, the shell 4 is covered outside the worm wheel and the worm, the top cover 5, the outer shaft baffle 6, the bearing 7, the inner shaft baffle 8 and the baffle 10 are sleeved on two sides of the worm 11 and used for supporting, the baffle 10 is sleeved on the end part of spiral teeth of the worm 11, the top cover 5 is sleeved on the end part of a shaft rod of the worm 11, the bearing 7 is arranged in the baffle 10, the outer shaft baffle 6 and the inner shaft baffle 8 are sleeved on a shaft rod of the worm 11, and the bearing 7 is arranged between the outer shaft baffle 6 and the inner shaft baffle 8; so that the roller is more stable and flexible in the rotating process.
