Description
One, technical field
The utility model relates to the coupling arrangement of a kind of planet wheel and planet carrier, and especially a kind of adaptation is used for the planet wheel of engineering machinery planetary speed reducer and the coupling arrangement of planet carrier.
Two, background technique
Planetary speed reducer generally adopts the differential type slowing-down structure, it mainly contains the combination of many group planet carriers, sun gear, gear ring, compositions such as input spline housing, motor is by driving the input spline housing, spline housing is connected the drive sun gear and rotates with the sun gear spline, each planet wheel drives the gear ring rotation under the drive of sun gear, thereby output torque, driving other parts rotates, it is a kind of important mechanical variable speed device, planet wheel and planet carrier are the vitals of planetary speed reducer, therefore the coupling arrangement of planet wheel and planet carrier is to the performance of planetary speed reducer with all play very important effect working life, the coupling arrangement of planet wheel and planet carrier is mainly used in all kinds of planetary speed reducers, such as engineering machinery walking mechanism, hoisting mechanism, jib lubbing mechanism, the planetary speed reducer of swirl gear etc. all needs the planet carrier Assembly, and the planet carrier Assembly is a crucial important components on planetary speed reducer; The coupling arrangement of existing planet wheel and planet carrier, under planetary speed reducer long-term work state, the bearing length time of planet wheel and circlip friction, cause the circlip wearing and tearing, disconnect, thereby cause the planet wheel internal bearings of planet carrier combination to deviate from, damage planet wheel, influence the performance and the working life of whole speed reducer.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides the coupling arrangement of a kind of planet wheel and planet carrier, has guaranteed the performance of planetary speed reducer, has prolonged the working life of planetary speed reducer.
For achieving the above object, the technological scheme that the utility model is taked is to include planet carrier, circlip, bearing, planet wheel, outer back-up ring and back-up ring, planet wheel is provided with endoporus, two ends in the endoporus of planet wheel are provided with draw-in groove, circlip is set to two and be separately positioned in the draw-in groove of endoporus of planet wheel, between two circlips, be provided with bearing, between circlip and bearing, be provided with back-up ring, bearing is set to be sleeved on the rotatingshaft of planet carrier, outer back-up ring is set to be connected to the outer end of the rotatingshaft of planet carrier, and outer back-up ring is set to connect with bearing contact type.
End at planet wheel, in the endoporus draw-in groove of planet wheel one end that a circlip is packed into, a back-up ring is put into planet wheel, the bearing of packing into then, again another part back-up ring is put into, subsequently another part circlip pack into planet wheel (the endoporus draw-in groove in, then the form of planet wheel by hot charging is contained on the rotatingshaft of planet carrier, the rotatingshaft clamping of outer back-up ring and planet carrier, owing to designed back-up ring, avoided the friction between circlip and the bearing, prolonged the working life of circlip, therefore guarantee the performance of planetary speed reducer, prolonged the working life of planetary speed reducer.
The utility model has designed, and back-up ring is set to include back-up ring I and back-up ring II, is provided with the back-up ring II between circlip at one end and the bearing, is provided with the back-up ring I between the circlip of the other end and bearing.
Four, description of drawings
Accompanying drawing is a schematic representation of the present utility model.
Five, embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include planet carrier 1, circlip 2, bearing 3, back-up ring I 4, planet wheel 5, outer back-up ring 6 and back-up ring II 7, planet wheel 5 is provided with endoporus, two ends in the endoporus of planet wheel 5 are provided with draw-in groove, circlip 2 is set to two and be separately positioned in the draw-in groove of endoporus of planet wheel 5, between two circlips 2, be provided with bearing 3, be provided with back-up ring II 7 between circlip 2 at one end and the bearing 3, between the circlip 2 of the other end and bearing 3, be provided with back-up ring I 4, bearing 3 is set to be sleeved on the rotatingshaft of planet carrier 1, outer back-up ring 6 is set to be connected to the outer end of the rotatingshaft of planet carrier 1, and outer back-up ring 6 is set to connect with bearing 3 contact-types.
In the present embodiment, bearing 3 is set to roller bearing.
End at planet wheel 5, in the endoporus draw-in groove of planet wheel 5 one ends that a circlip 2 is packed into, back-up ring II 7 is put into planet wheel 5, the bearing 3 of packing into then, again back-up ring I 4 is put into, subsequently another part circlip 2 is packed in the endoporus draw-in groove of planet wheel (5), then the form of planet wheel 5 by hot charging is contained on the rotatingshaft of planet carrier 1, of the rotatingshaft clamping of outer back-up ring 6 with planet carrier 1.
The characteristics of the utlity model has down:
1, the utility model is a kind of on the basis of protoplanet frame combination, increase by one group of high-strength abrasion-proof back-up ring of design, his external diameter is the same with hole size in the planet wheel 5, under the idle situation of speed reducer, when rotating, planet wheel bearing 3 no longer produces friction with circlip 2, thus the working life of having improved circlip 2.
2, because the utility model is a kind of reinforced planet carrier combination, having overcome the protoplanet frame is combined under the situation of speed reducer work, planet wheel bearing 3 rollers and circlip 2 produce friction, cause circlip 2 to damage, cause bearing 3 rollers to be deviate from, damage speed reducer, this structure has improved the working life of speed reducer.
