Description
Technical field
The present invention relates to a kind of gear structure, particularly a kind of mechanical type, there is the gear of overload protective function.
Background technique
Outer energy pipe rotating machine rifle motor commonly used provides power as driving, but the tube machine gun is many with respect to traditional automatic weapon amount of parts, complex structure, the design space compactness, and maintenance is poor.Be prone to clamping stagnation when debugging, because motor has certain overload capacity, while clamping stagnation occurring, even closed power supply, the whole swivel assembly of motor has because of inertial force the trend that continues rotation, and drives the driving mechanism rotation, and driving mechanism drives the feeding mechanism rotation.Because the tube machine gun does not have overload protecting mechanism; particularly driving mechanism does not have overload protecting mechanism; so can cause the component that body of a gun system strength is lower under the condition of large inertial force, such as dialling, bullet wheel etc. is destroyed, thereby brings certain safety issue and maintenance problem.
Summary of the invention
In prior art; tube machine gun driving mechanism does not have overload protecting mechanism; after the motor outage; driving mechanism continues rotation under the effect of inertial force; thereby lower component cause the technical problem of damage to body of a gun system strength; the purpose of this invention is to provide a kind of gear that can play overload protective function; this overload protection drive gear is controlled by the moment of torsion that motor is delivered to the feeding mechanism position, and while effectively having avoided tube machine gun clamping stagnation, motor continues the problem that output torque destroys feeding mechanism and other related components.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of overload protection drive gear, comprise gear outer ring and the inner ring gear of suit;
Described gear outer ring is provided with a plurality of mounting holes, is provided with top and top spring in each mounting hole;
One end and the top of described top spring are equipped with, and the other end is limited in mounting hole by top spring pin;
Described inner ring gear is provided with a plurality of locating slots corresponding with mounting hole, and this locating slot is for holding the transition section of top.
Preferably, described locating slot has the interior profile be complementary with the external frame that comes directly towards transition section.
Preferably, described gear outer ring is provided with a plurality of pin-and-holes corresponding with mounting hole, and top spring pin is arranged in the pin-and-hole of gear outer ring by interference fit.
Preferably, the quantity that described gear outer ring arranges mounting hole arranges a plurality of according to the size of gear transmission moment of torsion and the needs that transmit angle, make driving gear both meet the needs that moment of torsion transmits, and can after skidding, recover original transmission angle again.
Useful technique effect of the present invention is:
Overload protection drive gear of the present invention can be controlled the moment of torsion transmitted, and prevents from, because of overload, other component are caused to damage; Simultaneously; this overload protection drive gear has the function that overload is recovered transmission agency and recovered to transmit angular dependence; the size of transmitting torque arranges the mounting hole of suitable quantity and selects suitable top spring as required, thereby can be by the torque of this driving gear fine adjustment output.In addition; overload protection drive gear structure of the present invention is simply compact, volume is little, practical; while not only being used on the tube machine gun faults such as can effectively avoiding occurring getting stuck, blocking bullet, motor continues output torque destruction feeding mechanism component; and can be used in a plurality of fields of machinery industry, be worthy to be popularized.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further details.
As shown in Figure 1, Figure 2 and Figure 3, overload protection drive gear 7 of the present invention, comprise gear outer ring 1 and inner ring gear 2, and inner ring gear 2 is sleeved in gear outer ring 1.
Described gear outer ring 1 is provided with a plurality of mounting holes 101, and mounting hole 101 is through hole, is provided with top 4 and top spring 5 in each mounting hole 101; One end of this top spring 5 is equipped with top 4, and the other end is limited in mounting hole 101 by top spring pin 6; As shown in Figure 4, come directly towards 4 and there is the transition section 401 that cross-sectional area diminishes gradually.
Described inner ring gear 2 is provided with a plurality of locating slots corresponding with mounting hole 101 201, and this locating slot 201 is for holding the transition section 401 of top 4.
As shown in Figure 2, described locating slot 201 has the interior profile be complementary with the external frame that comes directly towards 4 transition sections 401.
As shown in Figure 2, described gear outer ring 1 is provided with a plurality of pin-and-holes corresponding with mounting hole 101 102, and top spring pin 6 is arranged in the pin-and-hole 102 of gear outer ring 1 by interference fit.
In the present embodiment, the quantity of the mounting hole 101 that gear outer ring 1 arranges arranges a plurality of according to the size of gear transmission moment of torsion and the needs of transmission angle, make driving gear both meet the needs that moment of torsion transmits, can, after skidding, by transmitting gear outer ring 1, recover original transmission angle again.
Further introduce the process of installing and using of overload protection drive gear of the present invention below in conjunction with accompanying drawing.
At first, the size of transmitting torque is calculated according to actual needs, thereby determines the quantity of mounting hole 101 and select suitable top spring 5, guarantees the accuracy of torque adjustment.Then inner ring gear 2 is sleeved in gear outer ring 1, swing pinion outer ring 1 or inner ring gear 2, make the mounting hole 101 on gear outer ring 1 corresponding with the locating slot 201 on inner ring gear 2.In each mounting hole 101 of then will come directly towards in order respectively 4, top spring 5 being packed gear outer ring 1 into, come directly towards 4 transition section 401 and insert matchingly in the locating slot 201 on inner ring gear 2.Finally by interference fit, will come directly towards in the pin-and-hole 102 that spring pin 6 is installed to gear outer ring 1, and be limited in mounting hole 101 thereby will come directly towards spring 5, the overload protection drive gear train installs into.
This overload protection drive gear is installed on transmission shaft 3, and the present embodiment is preferably installed by spline, is easy for installation and removal.When driving mechanism works, inner ring gear 1 is driven gear outer ring 1 synchronous rotary under the effect of the transition section 401 of a plurality of tops 4.When transmitting torque is greater than the transmitting torque of driving gear 7 itself; the transition section 401 compression top springs 5 of top 4 exit locating slot 201; be retracted in the mounting hole 101 of gear outer ring 1; thereby gear outer ring 1 and inner ring gear 2 are produced to skid; stop the transmission of moment of torsion, play the effect of overload protection.
After the unloading of driving mechanism output terminal, transmitting gear outer ring 1, coming directly towards 4 can reinsert in the locating slot 201 of inner ring gear 2 under the spring power effect of top spring 5, thereby makes driving gear 7 recover transmission agency.And a plurality of mounting holes 101 that gear outer ring 1 arranges, can make the driving angle relation before driving gear 7 recovers to skid by transmitting gear outer ring 1, easy to adjust.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
