Existing driving-shaft assembly deep groove ball bearing: be all on the ball of deep groove ball bearing, there is a bearing outer ring, then deep groove ball bearing is fixed on the head of flanged yoke by outer ring, deep groove ball bearing outer ring is fixed again with jump ring or alternate manner, annex is more, take the space of duplex jaw inside
Model utility content
The purpose of this utility model is exactly to solve the problem, and provides the driving-shaft assembly being with novel deep groove ball bearing structure, which reduces the annex at deep groove ball bearing position, strengthen deep groove ball bearing with this, thus increase the moment of torsion at this position, convenient installation.
To achieve these goals, the utility model adopts following technological scheme:
With the driving-shaft assembly of novel deep groove ball bearing structure, it comprises splined shaft assembly, described splined shaft assembly comprises slip shaft yoke (1) and dust-proof cover provided thereon (2) and flip sleeve (3), described splined shaft assembly two ends are provided with duplex section header part, and described duplex section header part has:
Be located at the welding jaw (4) of splined shaft assembly end, its head is provided with bearing support, the built-in deep groove ball bearing of described bearing support, and the through hole of described deep groove ball bearing is provided with a circle needle roller;
Be located at the flange jaw (6) of whole end part of driving shaft, its head arranges pivot pin, and this pivot pin is inserted in the through hole of deep groove ball bearing and coordinates with needle roller;
Be located at flange jaw and the duplex jaw (7) welded between jaw, the two ends of described duplex jaw respectively by Hooke's joint (8) with flange jaw with weld jaw assembly connection;
It is characterized in that, the excircle of described deep groove ball bearing is provided with concyclic assembling tangent plane (S), this assembling tangent plane place diameter of a circle is less than the external diameter of deep groove ball bearing, described bearing support has the inner ring structure coordinated with deep groove ball bearing, and the internal diameter of this inner ring structure is less than the external diameter of deep groove ball bearing.
Further, described assembling tangent plane place diameter of a circle 1-2mm less of the external diameter of deep groove ball bearing.
The utility model has following beneficial effect: the annex reducing deep groove ball bearing position, strengthens deep groove ball bearing, thus increase the moment of torsion at this position with this, convenient installation.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
As Figure 1-5, with the driving-shaft assembly of novel deep groove ball bearing structure, it comprises splined shaft assembly, described splined shaft assembly comprises slip shaft yoke 1 and dust-proof cover 2 provided thereon and flip sleeve 3, described splined shaft assembly two ends are provided with duplex section header part, and described duplex section header part has: the welding jaw 4 being located at splined shaft assembly end, and its head is provided with bearing support, the built-in deep groove ball bearing Q of described bearing support, the through hole of described deep groove ball bearing is provided with a circle needle roller; Be located at the flange jaw 6 of whole end part of driving shaft, its head arranges pivot pin, and this pivot pin is inserted in the through hole of deep groove ball bearing and coordinates with needle roller; Be located at flange jaw and the duplex jaw 7 welded between jaw, the two ends of described duplex jaw respectively by Hooke's joint 8 with flange jaw with weld jaw assembly connection.
The excircle of described deep groove ball bearing is provided with concyclic assembling tangent plane S, only the circle less than deep groove ball bearing external diameter need be processed out on the excircle of deep groove ball bearing in the process of processing, and the inner opening of machine direction and deep groove ball bearing (itself and through hole represent same structure) same angle, for the external diameter of deep groove ball bearing for 50mm, described assembling tangent plane place diameter of a circle then controls at 48mm, that is.Described assembling tangent plane place diameter of a circle 1-2mm less of the external diameter of deep groove ball bearing, this assembling tangent plane place diameter of a circle is less than the external diameter of deep groove ball bearing, described bearing support has the inner ring structure R (it is arranged on the cavity portion ingress of bearing support) coordinated with deep groove ball bearing, and the internal diameter of this inner ring structure is less than the external diameter of deep groove ball bearing, in this case, the internal diameter of this inner ring structure controls at 48.2mm, but bearing support other size for the cavity portion assembling deep groove ball bearing except inner ring structure needs to be greater than deep groove ball bearing, like this then deep groove ball bearing can be made to go slick in bearing support.The inner ring of deep groove ball bearing is fixed by the pivot pin welding jaw, and deep groove ball bearing can only in the running of fixing position, and such deep groove ball bearing can be fixed on bearing support inner ring structure and can not fall out.
Mounting type for this deep groove ball bearing is: when installing deep groove ball bearing, bearing support is sent into facing to the inner ring structure of bearing support with the assembling tangent plane S of deep groove ball bearing, after installation is entered, deep groove ball bearing is turned over and turn 90 degrees, just outwardly, such deep groove ball bearing is just fixed in bearing support inner ring structure and cannot pulls out the opening (above described through hole) of deep groove ball bearing.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
