Road, it is particularly in Expressway Construction, loading machine fills out digging, asphalt and coagulating cement earth material for subgrade engineering
Gather materials with charging etc. operation.Push soil can be additionally carried out, plane earth is scraped and draws the operations such as other machineries.Due to dress
Carrier aircraft has the advantages that operating speed is fast, efficiency high, mobility are good, operation is light, therefore it turns into the cubic metre of earth and stone in engineering construction
One of main machine of construction.Output shaft of gear-box is the power output part of loading machine, to branch during running at high speed
Holding intensity, connection reliable lock and sealing has a higher requirement, but many loading machine gearboxes used now
Output shaft both ends connection reliable lock is poor, easily occurs landing phenomenon on output shaft after O-ring installation, and the supporting of output shaft is strong
Spend bad, long-play influence stationarity.
Utility model content
The utility model overcome loading machine gearbox output shaft both ends connection reliable lock it is poor, O-ring on output shaft
Easily occur sliding phenomenon after installation, the bearing strength of output shaft is bad, and long-play influences the deficiency of stationarity, there is provided
A kind of loading machine gearbox output shaft, output shaft both ends connection reliable lock is good, is not in after O-ring installation on output shaft
Phenomenon is slid, the bearing strength of output shaft is good, and supporting is steady reliable, and long-play does not interfere with stationarity yet.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of loading machine gearbox output
Axle, including output shaft body, output shaft body are equipped with locking screw on the outer wall of both ends, export shaft body both ends outward flange
Some nut check grooves are equipped with, exports and is sequentially provided with left spline, middle spline, right spline from left to right in shaft body, export
Sealing is provided with shaft body between locking screw and left spline, sealing outer wall is from close left splined end to the other end towards flare
Oblique setting, export and be provided with left bearing support in shaft body on the right side of left spline, middle spline left side is provided with auxiliary in output shaft body
Bearing support is helped, exports and is provided with right bearing support on the right side of spline among in shaft body.
Export after shaft body both ends connection locking nut by the flange of sleeving and riveting locking nut inward flange to nut check groove
In, the locking of locking nut is realized, it is good to connect reliable lock.Be set with O-ring on sealing outer wall, due to sealing outer wall from
It is obliquely installed outwardly to the other end close to left splined end, therefore it is not in slide now to export O-ring in shaft body running
As.Export and left bearing support, auxiliary bearing support, right bearing support are set in shaft body, it is strong to substantially increase bearing
Degree, bearing are more steady reliable.This loading machine gearbox output shaft both ends connection reliable lock is good, O-ring on output shaft
Be not in landing phenomenon after installation, the bearing strength of output shaft is good, and supporting is steady reliable, and long-play does not interfere with flat yet
Stability.
Preferably, middle spline is rectangular spline.Rectangular spline connection is reliable.
Preferably, left spline and right spline are involute spline.Involute spline bearing capacity is strong, easily automatic fixed
The heart, installation accuracy are high.
Preferably, output shaft body both ends are equipped with projection, nut check groove is arranged on projection outer wall.Projection is convenient
The arrangement of nut check groove, while facilitate the connection of locking nut.
Preferably, it is provided with sealing cylinder face between the output upper right bearing support of shaft body and right spline.Sealing cylinder
Face improves the sealing property of output shaft body installation.
Preferably, sealing external diameter is less than left spline external diameter.This structure setting improves the reliability of O-ring installation.
Compared with prior art, the beneficial effects of the utility model are：The connection locking of loading machine gearbox output shaft both ends
Good reliability, after O-ring installation be not in landing phenomenon on output shaft, the bearing strength of output shaft is good, and supporting is steady reliable,
Long-play does not interfere with stationarity yet.
