Abstract
This utility model relates to technical field of bearings, and especially one completely fills needle bearing.One completely fills needle bearing, and this bearing has the needle roller of full dress, and described needle roller side is provided with exterior supporting, and the opposite side of needle roller is provided with built-in supporting, and the axial length of described inside and outside assembling set is identical, and needle roller at least one end part is stretched out built-in supporting or exterior supporting.Needle roller by built-in supporting and exterior supporting be fixed together, not only efficiently reduced the assembly process of customers' place, but also substantially increases the efficiency of assembling of customers' place by this utility model.
Description
Technical field
This utility model relates to technical field of bearings, and especially one completely fills needle bearing.
Background technology
Planetary gear, with completely filling needle bearing, is mainly installed in planetary gear hole, plays and supports and the effect of operating.By
Being relatively small in size in planetary gear, and require under reduced size, bearing load is bigger；So needle bearing uses full dress,
I.e. without retainer structure.Owing to not having retainer, bearing cannot keep together, and transportation middle (center) bearing easily falls apart
Fall.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, it is provided that one completely fills needle roller axle
Hold.
This utility model solves the technical scheme is that one of its technical problem and completely fills needle bearing, and this bearing has
Having the needle roller of full dress, described needle roller side to be provided with exterior supporting, the opposite side of needle roller is provided with built-in supporting, described inside and outside assembling
The axial length of set is identical, and needle roller at least one end part is stretched out built-in supporting or exterior supporting.
Further, described needle roller is single-row needle roller, and needle roller one end part is stretched out built-in supporting or exterior supporting.
Further, described needle roller is duplex needle, is provided with pad between needle roller, and needle roller one end part is stretched out built-in supporting
Or it is exterior supporting.
Further, described needle roller is that three row and three arrange above needle roller, is provided with pad, all portions, needle roller two ends between needle roller
Point stretch out built-in supporting or exterior supporting.
The beneficial effects of the utility model are: this utility model by needle roller by built-in supporting and exterior supporting be fixed on one
Rise, not only efficiently reduce the assembly process of customers' place, but also substantially increase the efficiency of assembling of customers' place.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model embodiment one.
Fig. 2 is the structural representation of this utility model embodiment two.
Fig. 3 is the structural representation of this utility model embodiment three.
In figure: 1. bearing, 2. needle roller, the most exterior supporting, the most built-in supporting, 5. pad.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification only to show
Meaning mode illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
Embodiment one
One as shown in Figure 1 completely fills needle bearing, and this bearing 1 has the needle roller 2 of full dress, and needle roller 2 is single-row needle roller, rolling
Pin 2 side is provided with exterior supporting 3, and the opposite side of needle roller 2 is provided with built-in supporting 4, and the axial length of inside and outside assembling set 4,3 is identical,
Needle roller 2 one end part stretches out built-in supporting 4 or exterior supporting 3.
Embodiment two
As in figure 2 it is shown, be with the difference of embodiment one: needle roller 2 is duplex needle, is provided with pad between needle roller 2
5, needle roller 2 one end part stretches out built-in supporting 4 or exterior supporting 3.
Embodiment three
As it is shown on figure 3, be with the difference of embodiment one: needle roller 2 is that three row and three arrange above needle roller, needle roller 2
Between be provided with pad, needle roller 2 two ends all part stretch out built-in supporting 4 or exterior supporting 3.
Assembling process: will stretch out needle roller 2 part correspondence and fill in gear hole and match between axle, uses special tooling to be pressed in rolling
On pin 2 end face, inside and outside assembling set 4,3 automatic spring.
Above-mentioned embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification, all should contain at protection model of the present utility model
In enclosing.
