Abstract
The utility model discloses an improved planetary gear assembly comprising a planetary gear. The utility model is characterized in that an inner side of the planetary gear is provided with a group of flat top needle rollers along a peripheral direction, and an outer side of each of the flat top needle rollers is provided with a needle roller retainer ring, besides, an inner side of each of the flat top needle rollers is provided with an inner cylinder liner. The utility model is advantageous in that in the improved planetary gear assembly, the outer cylinder liner of a bearing can be removed, because the flat top needle rollers can be directly disposed in the planetary gear; the structure is compact, the outer diameter of the planetary gear can be reduced, therefore the size of the whole speed reducer can be reduced, and the resources can be saved; the improved planetary gear assembly has a significant meaning for the miniaturized design of the speed reducer.
Description
Technical field
The utility model relates to the speed reducer accessory, relates in particular to improved planet wheel assembly.
Background technique
Existing planet wheel assembly is made up of with back-up ring planet wheel, bearing and hole, receives the restriction of bearing, and it is bigger that planet wheel is done; Thereby make the also corresponding increase of whole reducing mechanism; Cause the speed reducer build heavy, influence its working efficiency, also caused the waste of resource.Therefore, should provide a kind of new technological scheme to solve above-mentioned asking questions.
The model utility content
The purpose of the utility model is: to above-mentioned deficiency, provide that a kind of structure is small and exquisite, high working efficiency, the improved planet wheel assembly that economizes on resources.
For realizing above-mentioned purpose; The technological scheme that the utility model adopts is: improved planet wheel assembly, comprise planet wheel, and the planet wheel inboard evenly is furnished with one group of flat-top needle roller along its circumferencial direction; The outside of said flat-top needle roller is provided with the needle roller back-up ring, and the inboard of said flat-top needle roller is provided with the inner casing spirit.
The utility model has the advantages that: the improved planet wheel assembly of the utility model; Because the flat-top needle roller is directly installed in the planet wheel, be equivalent to cancel the outer shell spirit of bearing, compact structure; Can reduce the external diameter of planet wheel; Thereby reduce the size of whole speed reducer, practiced thrift resource, the miniaturization Design of speed reducer is significant.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the utility model structure sectional view.
Wherein: 1, planet wheel, 2, flat-top needle roller 3, needle roller back-up ring, 4, the inner casing spirit.
Embodiment
As shown in Figure 1, the improved planet wheel assembly of the utility model comprises planet wheel 1, and planet wheel 1 inboard evenly is furnished with one group of flat-top needle roller 2 along its circumferencial direction, and the outside of flat-top needle roller 2 is provided with needle roller back-up ring 3, and the inboard of flat-top needle roller 2 is provided with inner casing spirit 4.The improved planet wheel assembly of the utility model; Because flat-top needle roller 2 is directly installed on 1 li of planet wheel, be equivalent to cancel the outer shell spirit of bearing, compact structure; Can reduce the external diameter of planet wheel 1; Thereby reduce the size of whole speed reducer, practiced thrift resource, the miniaturization Design of speed reducer is significant.
