Problems solved by technology

Since the rotary machine gun does not have an overload protection mechanism, especially the transmission mechanism does not have an overload protection mechanism, under the condition of large inertial force, the parts with low strength of the gun body system, such as the dial wheel, etc. will be destroyed, which will bring certain damage. safety and maintainability issues

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 and image 3 As shown, the overload protection transmission gear 7 of the present invention includes a gear outer ring 1 and a gear inner ring 2 , and the gear inner ring 2 is sleeved in the gear outer ring 1 .

[0025] The gear outer ring 1 is provided with a plurality of mounting holes 101, and the mounting holes 101 are through holes, and each mounting hole 101 is provided with a plug 4 and a plug spring 5; one end of the plug spring 5 is arranged in cooperation with the plug 4, and the other end Restricted in the installation hole 101 by the plug spring pin 6; as Figure 4 As shown, the plug 4 has a transition section 401 whose cross-sectional area gradually decreases.

[0026] The gear inner ring 2 is provided with a plurality of positioning grooves 201 corresponding to the mou...

Abstract

An overload protection transmission gear comprises a gear outer ring and a gear inner ring which are arranged in a sleeved mode. The gear outer ring is provided with a plurality of mounting holes, and an ejection head and an ejection head spring are arranged in each mounting hole, wherein one end of the ejection head spring is matched with the ejection head, and the other end of the ejection head spring is limited into the mounting hole through an ejection head spring pin; the gear inner ring is provided with a plurality of location grooves corresponding to the mounting holes, and the location grooves are used for containing transition sections of the ejection heads. The overload protection transmission gear can control transmitted torque and prevent other parts from being damaged by overload.

Description

technical field [0001] The invention relates to a gear structure, in particular to a mechanical gear with overload protection function. Background technique [0002] External energy tube machine guns are often driven by motors to provide power, but compared with traditional automatic weapons, tube machine guns have a large number of parts, complex structures, compact design space, and poor maintainability. It is easy to get stuck during debugging. Because the motor has a certain overload capacity, when stuck, even if the power is turned off, the entire rotating assembly of the motor has a tendency to continue to rotate due to inertial force, and drives the transmission mechanism to rotate, and the transmission mechanism drives the bomb supply. The machine rotates. Since the rotary machine gun does not have an overload protection mechanism, especially the transmission mechanism does not have an overload protection mechanism, under the condition of large inertial force, the p...
