Definitions
- the invention relates to a screw with a drive having screw head according to the preamble of claim 1.
- DE 35 01 414 A1 discloses a screw with a drive having screw head.
- the provided for transmitting the torque cam have an orthogonal to
- Such screws are particularly suitable for automatic screwdriving tools, wherein a particularly simple coupling of a screwdriver bit to the screw, in particular with constantly rotating tools, by the running in the direction of insertion tendency of the cam head surface is achieved. It is an object of the invention to provide an improved drive, the introduction of a
- the cams are arranged and designed in their radial extension in such a way that they center a tool introduced into the screw drive, and further, the head face is divided into a first face and a second face, each tilted in a rotational direction.
- the screw By dividing the head face into two faces, the screw can be quickly placed on a turning tool in the free direction of rotation. Such a design proves to be particularly advantageous for small and very small screws because their handling, especially the touchdown on a
- the surfaces are arranged so that the two surfaces intersect in a cutting line located in the center of the cam.
- Screw axis lying plane inclined towards the center of the screw This has the consequence that not only the driving elements of a rotary tool with the recesses of the cams can be facilitated in the circumferential direction, but also a match in the radial direction is enforced.
- an inclination of the cutting line of about 10 ° to 30 ° relative to the orthogonal to the screw axis plane can be selected.
- the two surfaces of the head face at their cutting line an angle between 120 ° and 160 °. Since, starting from the end facing the screw head, the inclination on the head surface reduces the effective lateral surfaces of the cams for torque transmission, this inclination angle results in an ideal setting with regard to the effectiveness of the introduction and the torque transmission.
- the intersection of the first surface with the second surface is rounded.
- the rounding of the cutting line leads to easier feeding of the tool, as a tilting of the turning tool and cutting edge is avoided.
- Fig. 1 is a perspective view of a screw
- Fig. 2 is a plan view of the screw head
- Fig. 3 is a section B-B
- Fig. 4 is a section A-A.
- Fig. 1 shows a screw 10 with an introduced into the screw head 12 drive 14.
- the drive 14 of the screw cam 16 which by
- a cam 16 has a cam head surface 18 which has two surfaces 18a, 18b which are inclined with respect to a plane orthogonal to the screw axis. On the function of the respective inclinations of the cam head surface 18 will be discussed in more detail in the following figures.
- Fig. 2 shows the top view of a screw according to the invention, said three cams 16 having in their cam center a linear abutment portion which extends over the height of the cam to center a tool in the screw, in the middle of the Cam 16 lie.
- the cutting lines 20 lie on the respective bisector of the relevant for the width of the cam 16 circular sector. Further, the cutting lines 20 are shown, the sections, in the Fig. 3, the section BB and in Fig. 4, the section AA, are explained in more detail.
- Fig. 3 shows the section BB, which intersects the screw head in the center of the cam 16.
- the section line 20 of the surfaces 18a and 18b is inclined relative to a plane E orthogonal to the screw axis in the radial direction by an angle ⁇ .
- This inclination ⁇ facilitates the insertion of a tool in the radial direction, as a Slip is forced into the central centering area between the cams.
- this automatically passed into the center of the screw.
- FIG. 4 shows the illustration of the section A-A from FIG. 2, wherein it is clearly recognizable that the two surfaces which intersect in a section line 20 are each inclined in a direction of rotation with respect to the plane E lying orthogonally to the screw axis.
- the section line 20 of the two inclined surfaces 18a, 18b is located in the center of the cam. Accordingly, it is ensured that, depending on the location of
- Driving elements of a rotary tool to be used the screw 10 must implement only a minimum rotational movement, so that the driving elements in a position corresponding to the recesses to the cams can be made suitable.
- the two surfaces include an angle ß of about 150 °. This angle is chosen so as to ensure the insertion aid and the necessary slipping of the entraining elements on the cam head surface 18 and yet realizes a maximum cam side surface 22, so that the necessary torque can be transmitted easily.
