Abstract
The utility model belongs to the technical field of bearing equipment, especially, relate to a robot reduction gear bearing. A supporting flange's inside be connected through connecting bolt and the 2nd supporting flange, a supporting flange, the 2nd supporting flange's inboard be provided with bearing inner race, bearing inner race is connected through rotatory rolling element and a supporting flange, the 2nd supporting flange inboard raceway, bearing inner race and a supporting flange, the 2nd supporting flange formula structure as an organic whole. Its improves that the back is small, light in weight, simple structure, directly be processed into bearing inner race and supporting flange and an organic whole with robot angular contact ball bearing inner circle on supporting flange, two ditch centre -to -centre spacing on the bearing are accurate, and the bearing atress is even, and the operation is nimble, and displacement volume accuracy improves the motion stationary of robot, and the action is accurate. Debugging installation, easy maintenance, precision height.
Description
Technical field
This utility model belongs to bearing apparatus technical field, especially relates to a kind of robot decelerator bearing.
Background technology
Former external product is to cast a pivot flange a with spheroidal graphite cast-iron, installs a pair of machine after pivot flange a is processed
People angular contact ball bearing b, is interference fit.After installation, bearing inner ring raceway circularity is destroyed deformation, bearing rotation precision
Reduce, rotation is unstable, not smooth, have resistance.Impact robot motion is steady and action is accurate.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, the simple robot of structure slows down
Device bearing.
For reaching above-mentioned purpose, this utility model employs following technical proposal: it include the first pivot flange, second
Staying orchid, connecting bolt, bearing inner race, rotary rolling body；Connecting bolt and the are passed through in the inside of the first described pivot flange
Two pivot flanges are attached；The first described pivot flange, the inner side of the second pivot flange are provided with bearing inner race, outside bearing
Circle is connected with the first pivot flange, the second pivot flange inboard raceways by rotary rolling body；Described bearing inner race and first
Pivot flange, the second pivot flange are integral type structure.
Compared with prior art, a kind of advantage of this robot decelerator bearing is: small volume, weight after its improvement
Gently, structure is simple；Robot angular contact ball bearing inner ring is directly processed on pivot flange bearing inner race and pivot flange
With one, accurately, shaft strength uniformly, goes slick bearing two ditch centre-to-centre spacing, and displacement accurately, improves robot motion and puts down
Surely, action is accurate.Adjustment and installation, easy to maintenance, high precision.

Fig. 2 is this utility model profile.
Fig. 3 is new inner ring one structural representation of this practicality.
Fig. 4 is new inner ring two structural representation of this practicality.
Description of reference numerals: the first pivot flange 1, the second pivot flange 2, connecting bolt 3, bearing inner race 4, rotary rolling
Body 5, bearing outer ring 6.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is further described.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and specifically
Embodiment, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only used
To explain this utility model, it is not used to limit this utility model.
As Figure 1-Figure 4, this specific embodiment adopts the following technical scheme that it includes the first pivot flange 1, second
Pivot flange 2, connecting bolt 3, bearing inner race 4, rotary rolling body 5；The inside of the first described pivot flange 1 is passed through to connect spiral shell
Bolt 3 is attached with the second pivot flange 2；The first described pivot flange 1, the inner side of the second pivot flange 2 are provided with bearing
Inner ring 4, bearing outer ring 6 is connected with the first pivot flange 1, the second pivot flange 2 inboard raceways by rotary rolling body 5；Described
Bearing inner race 4 and the first pivot flange 1, the second pivot flange 2 be integral type structure.
Described pivot flange 1,2 adopts g20cr2ni4Material, at pivot flange raceway case-carbonizing 0.8-1.0
Reason, raceway surface adopts high-frequency quenching, makes raceway case hardness reach hrc60-62.Pivot flange center portion hrc30-
35；The raising of bearing inner race raceway hardness makes bearing wearability improve, pivot flange inner hardness mental retardation withstanding shocks property load,
Robot harmonic wave speed reducing machine performance is made to be improved.
The above, only in order to the technical solution of the utility model is described and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover in the middle of right of the present utility model.
