Overload protection arrangement between gear outer ring described in inner ring, the overload protection arrangement include being arranged on the gear outer ring
Locked groove, the ejector pin being arranged on the inner ring gear and the elastic component that the ejector pin is pushed to the locked groove, the locked groove have
The cone tank of one conical indentation, the end of the ejector pin have the card division that can be embedded in the taper.
Preferably, the one end of the inner ring gear is provided with the groove of " L " shape, and the gear outer ring rotating is arranged on institute
State in groove.
Preferably, the locked groove is embedded on the gear outer ring by screw.
It is further preferred that the gear outer ring, which corresponds to the locked groove, is provided with mounting hole, overload protection arrangement further includes
Adjusting knob, the adjusting knob are threaded on the mounting hole, and described elastic component one end is supported and is located on the ejector pin, separately
One end is supported and is located on the adjusting knob.
It is further preferred that be provided with through hole at the adjusting knob axle center, the one end of the ejector pin is from the through hole
In pass through and expose outside the inner ring gear.
It is further preferred that the other end of the ejector pin is provided with ball grooves, ball is embedded with the ball grooves.
Preferably, the elastic component is multiple butterfly springs.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
When the torque overload that external impacts are on bevel gear, and bevel gear is subject to, protective device plays a role, and ejector pin overcomes
The elastic force of elastic component departs from from locked groove, and inner ring gear, gear outer ring can mutually rotate, so that gear field of conjugate is rushed
Hit power to reduce moment so that gear teeth damage.The service life of bevel gear is improved, extends maintenance cycle, so that significantly
Cost is saved.

Embodiment
Shown embodiment is further described the utility model below in conjunction with the accompanying drawings：
Referring to shown in attached drawing 1, a kind of marine gear transmission component, including propeller shaft 1, rotation axis 2 and set respectively
First bevel gear 3 and second bevel gear 4 between propeller shaft 1, rotation axis 2, wherein first bevel gear 3 include fixing with axis
Inner ring gear 31, the gear outer ring 32 with conical tooth that is rotatably arranged on outside inner ring gear 31, and be arranged in gear
The overload protection arrangement between 31 gear outer rings 32 is enclosed, the one end of inner ring gear 31 is provided with the groove of " L " shape, gear outer ring
32 are rotatably arranged in groove.
Overload protection arrangement includes the locked groove 5 being arranged on gear outer ring 32,6 and of ejector pin being arranged on inner ring gear 31
Ejector pin 6 is pushed to multiple butterfly springs 8 of locked groove 5 to, locked groove 5 has the cone tank 51 of a conical indentation, the end tool of ejector pin 6
The card division of taper can be embedded in by having.Locked groove 5 is embedded on gear outer ring 32 by screw 52, and gear outer ring 32 corresponds to locked groove 5 and sets
There is mounting hole.
Overload protection arrangement further includes adjusting knob 7, and adjusting knob 7 is threaded on mounting hole, 8 one end of butterfly spring
To being located on ejector pin 6, the other end is supported and is located on adjusting knob 7.
Through hole 71 is provided with 7 axle center of adjusting knob, the one end of ejector pin 6 is passed through from through hole 71 and exposed in gear
