Spline (but being not limited to spline) is linked together with reducer shell；Bull gear is supported by deep groove ball bearing, deep groove ball bearing it is interior
Circle is mounted on planet carrier；The axial force of sun gear passes through two thrust bearings of left and right ends, transmits the force to planet carrier, from
And offset axial force.Above-mentioned technical proposal can be widely applied to various gearboxes.
Bull gear is positioning by the purpose that two deep groove ball bearings support, while bull gear can be made to run smoothly；Due to
The retarder of the design is the external tooth output power by bull gear, and to improve gear capacity, general gear is using oblique
Tooth will generate axial force in engagement process, and the inner ring of deep groove ball bearing is mounted on planet carrier, can be by axial force transmission
To planet carrier, and the retarder planet carrier connects together with shell, to counteract axial force.
By spline fixed carrier in reducer structure, pass through bull gear output power；Planet carrier and shell are linked as one
Body is while there are also compact-sized, to offset the benefit of axial force backward to achieve the purpose that fixed carrier.
Axis is mounted in the annular groove that planet carrier is equipped with snap ring, and effect is axially position deep groove ball bearing, prevents it
Axial motion；Hole is mounted in the annular groove that planet carrier is equipped with snap ring, and effect is axially position thrust bearing.
To sum up, the planetary gear speed reducer in the design is compact-sized, simple, and positioning method is novel, such as sun gear both ends
Two thrust bearings are also equipped with for offsetting axial force (since the input terminal of the design retarder is driving motor, driving motor
It is cannot have axial force)；Bull gear is positioned by two deep groove ball bearings, while deep groove ball bearing inner ring is mounted on planet carrier
On.
