Abstract
The utility model discloses a flexible shaft transmission shaft head structure which comprises a flexible shaft (1), and is characterized in that the end part of the flexible shaft (1) is connected with a shaft head (2) in a forging and pressing manner; a shaft shoulder (3) is arranged at one end, close to the inner side of the flexible shaft (1), of the shaft head (2); a positioning shaft sleeve (4) is connected outside the shaft head (2) in a sleeving manner; a protection steel tube (5) is connected outside the positioning shaft sleeve (4) in a sleeving manner; positioning holes (6) are formed in the positioning shaft sleeve (4) and the protection steel tube (5) respectively; and the positioning pins (7) are connected in the positioning holes (6) in a penetrating manner. The flexible shaft transmission shaft head structure is simple in structure, ingenious in design and reasonable in layout, and prevents the flexible shaft from being subjected to axial tension basically.
Description
Technical field
The utility model relates to a kind of linkage structure, particularly a kind of soft axle transmission shaft head structure of spindle nose part.
Background technique
In the structure of torque transfer; a kind of structure of utilizing flexible axle to carry out torque transfer is arranged; although this soft axle transmission has the advantages such as strong, the restricted degree of flexibility is low; but the structural feature due to flexible axle itself; when it is subject to axial tension that the feed movement because of main frame vertical rotation direction produces; because flexible axle itself is directly stressed, therefore as easy as rolling off a logly cause that its steel wire disconnects, fracture, even extract the protection steel pipe of its end portion, affect stability and the working life of its transmission.Therefore need now a kind of novel flexible axle shaft head structure that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, fundamentally prevents that flexible axle itself is subject to the soft axle transmission shaft head structure of axial tension.
Technical solution of the present utility model is: a kind of soft axle transmission shaft head structure; comprise flexible axle 1; it is characterized in that: the end of described flexible axle 1 is connected with spindle nose 2 by the mode of forging and stamping; spindle nose 2 is provided with the shaft shoulder 3 near an end of flexible axle 1 inboard; be socketed with positioning shaft sleeve 4 outside spindle nose 2; be socketed with protection steel pipe 5 outside positioning shaft sleeve 4, on positioning shaft sleeve 4 and protection steel pipe 5, be respectively arranged with positioning hole 6, the interior cross-under of positioning hole 6 has locating stud 7.
The positioning hole 6 of described supporting setting and locating stud 7 are a plurality of, and equidistantly are arranged on positioning shaft sleeve 4 and protection steel pipe 5.
The utility model compared with the existing technology, has following advantage:
The soft axle transmission shaft head structure of this kind of structural type, for traditional flexible axle structure when being subject to axial tension, steel wire can occur to disconnect, ruptures, even its spindle nose is partly extracted to the problem of destroying fully that causes, shaft head at flexible axle is provided with a set of special structure, this nested structure can prevent directly bearing tension of spindle nose part, guarantees that flexible axle not there will be the problems referred to above.And its preparation process is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As shown in Figure 1: a kind of soft axle transmission shaft head structure, comprise flexible axle 1, end at flexible axle 1 is connected with spindle nose 2 by the mode forged and pressed, this spindle nose 2 is provided with the shaft shoulder 3 near an end of flexible axle 1 inboard, be socketed with positioning shaft sleeve 4 outside spindle nose 2, one end of positioning shaft sleeve 4 withstands on the shaft shoulder 3, and spindle nose 2 can rotate with respect to positioning shaft sleeve 4 under the drive of flexible axle 1; Be socketed with protection steel pipe 5 outside positioning shaft sleeve 4; be respectively arranged with positioning hole 6 on positioning shaft sleeve 4 and protection steel pipe 5; in the interior cross-under of positioning hole 6, locating stud 7 is arranged, the described positioning hole matched 6 and locating stud 7 are a plurality of, and equidistantly are arranged on positioning shaft sleeve 4 and protection steel pipe 5 simultaneously.
The utility model embodiment's soft axle transmission shaft head structure, because the end at flexible axle 1 is socketed with spindle nose 2, and be outside equipped with positioning shaft sleeve 4 and the protection steel pipe 5 be fixedly connected with at spindle nose 2, in the process of therefore rotating at flexible axle 1, carry out the transmission of moment of torsion by positioning shaft sleeve 4 and protection steel pipe 5, and when flexible axle 1 is subject to axial pulling force, equally due to the existence of positioning shaft sleeve 4 with protection steel pipe 5, pulling force can not act directly on flexible axle 1, but pass to the various mechanisms that are arranged on flexible axle 1 spindle nose, prevent that flexible axle 1 is destroyed because of axially loaded, guarantee the stability that flexible axle 1 moment of torsion transmits, extend its working life.
Claims (2)
1. a soft axle transmission shaft head structure; comprise flexible axle (1); it is characterized in that: the end of described flexible axle (1) is connected with spindle nose (2) by the mode of forging and stamping; near flexible axle (1), an inboard end is provided with the shaft shoulder (3) to spindle nose (2); be socketed with positioning shaft sleeve (4) outside spindle nose (2); be socketed with protection steel pipe (5) outside positioning shaft sleeve (4); be respectively arranged with positioning hole (6) on positioning shaft sleeve (4) and protection steel pipe (5), the interior cross-under of positioning hole (6) has locating stud (7).
2. soft axle transmission shaft head structure according to claim 1 is characterized in that: the positioning hole of described supporting setting (6) and locating stud (7) be for a plurality of, and equidistantly be arranged on positioning shaft sleeve (4) and protect on steel pipe (5).
