Definitions
- the invention relates to a rotationally fixed as part of a transmission on a shaft or the like to be arranged SSrad. It relates in particular to a helical gear whose tread formed in the shape of a ring gear is formed by molding a base body with a plastic.
- toothed or helical gears made of metal generally have a higher mechanical strength compared to existing wheels made of plastic, but often cause when used in a transmission not inconsiderable running noise. Therefore, it is known to form helical gears in a sense in a hybrid design by their basic body made of a mechanically stable and wear-resistant material, such as metal, and this base body to form the tread is surrounded with a material which has good sliding properties. This ensures that such screw wheels on the one hand have the mechanical stability required for their intended use, but on the other hand have a high level of smoothness in operation.
- a corresponding helical gear is known, for example, from EP 1 339 596 B1.
- a toothed wheel designed as a worm gear is described, which is also referred to as a so-called built gear.
- the corresponding worm wheel has a plastic toothed ring, which is mechanically stabilized in its radially central region by axial flanges arranged axially on both sides.
- the individual segments of the worm wheel, so the existing plastic sprocket and the metallic flanges, are through at the flanges formed, extending in the axial direction through the plastic toothed ring and engaging with corresponding recesses of the respective other flange engaging projections and fixedly guided by means of axially guided through the assembly screws.
- this structure requires a relatively high installation effort in the production of the helical gear.
- a higher outlay on production results from the fact that the individual components of the helical gear may only have relatively small tolerances, so that they can be reliably connected to one another.
- a reduction of the manufacturing costs and thus the manufacturing costs can be achieved by the produced in the above-mentioned solution separately by way of injection molding outer plastic ring gear is produced by direct encapsulation of a mechanically stable, for example consisting of aluminum body with the plastic.
- a mechanically stable for example consisting of aluminum body with the plastic.
- measures must be taken to ensure a safe, even the transfer of larger moments permitting connection between the body and the sprocket.
- the object of the invention is to provide a to be realized by encapsulation of a mechanically stable base body with a plastic helical gear, which meets these requirements.
- a corresponding constructive design of the helical gear is to be achieved in particular between the body and the outer, made of plastic sprocket connection, the strength of which allows the transmission of large moments in the intended use of the helical gear reliable.
- the components of the fferrades should also be designed so that after encapsulation of the body with the sprocket little or no reworking for eliminating approach lugs or for smoothing weld lines is required.
- the object is achieved by a helical gear with the features of the main claim.
- Advantageous training or further developments of the errades invention are given by the dependent claims.
- the proposed to solve the problem helical gear consists of a designed as a flange body whose disc-shaped area is encapsulated to form a ring gear with a plastic.
- the reduced-diameter portion formed on the disc-shaped portion corresponding to the typical flange shape forms a hub for rotationally fixed mounting of the helical gear on a shaft.
- the disk-shaped region of the flange has axially on both sides in each case a plurality of recesses distributed on its circumference and extending predominantly in the axial direction but not projecting through the disk-shaped region.
- the recesses are dovetail-shaped, so that the remaining between the recesses portions of the outer periphery of the disc-shaped portion are undercut by extending in the axial direction edges of the recesses.
- the plastic flows into the recesses and under the edges which undercut or undercut the sections which have stopped between the recesses.
- the plastic which forms the sprocket due to a correspondingly shaped injection mold, during curing or solidification with the flange a rigid, positive connection.
- the recess and its special shape provide for an axial, radial and fixed in the circumferential direction of the helical gear seat of the ring gear.
- the recesses extending into this area from both axial sides of the disc-shaped area are arranged so that the recesses extending from one axial outer side of the disc-shaped area are offset relative to those of the respective other axial outer side.
- said recesses each protrude alternately from one and the other axial outside of the disc-shaped area in this area.
- the recesses are also advantageously designed so that they extend to the axial outer sides of the disc-shaped area, with respect to their extent to the circumference.
- a tight fit of the plastic toothed ring on the flange is achieved by the formation of the recesses, wherein advantageously at the same time an axial expansion possibility is given under thermal loads.
- the hub-facing axial outer surface of the disc-shaped region radially below the recesses on a circumferential, annular sprue.
- the plastic can be injected from this side, directed to the beads, in a correspondingly formed injection mold.
- a particularly uniform pressure distribution of the injected plastic material within the sprue is achieved by the beads.
- this groove extends in the axial direction up to the level of the holes introduced into the runner adjacent to the beads into the disk-shaped area.
- the holes in turn are guided in the axial direction to the aforementioned groove or slot.
- the beads are filled with the plastic. After the overflow of the plastic flows through the sprue and the holes in the slot or the radially projecting into the disc-shaped region groove and rises in the groove radially outward. The radially outer region of the flange is then finally flowed around by the further nachf jobden plastic to form the ring gear.
- the flange of the helical gear according to the invention may consist of different materials. Preferably, however, it consists of metal, for example aluminum. But also a production of glass fiber reinforced plastic comes into consideration.
- To form the ring gear is preferably a polyamide use.
- FIG. 1 shows the flange of a first embodiment of the helical gear according to the invention in a plan view from the radial direction.
- FIG 4 shows the flange according to FIG. 3 after the encapsulation with plastic.
- FIG. 5 A further embodiment of the helical wheel according to the invention with encapsulated flange in a three-dimensional representation
- Fig. 6 The flange of the embodiment of FIG. 5 during the coating with plastic in the appropriate tool in a sectional view.
- FIG. 1 shows the base body 1, which has not yet been coated with plastic, of a first embodiment of the helical gear according to the invention in a plan view from the radial direction r.
- the main body 1 is, as can be seen, formed in the shape of a flange.
- a circumferential plastic toothed ring 2 is later formed on the radial end face of its disc-shaped region 1 '.
- To the disc-shaped region 1 ' is reduced in its diameter portion 1 "formed, which forms the hub 1" of the later, provided for non-rotatable mounting on a shaft or the like b lusterrades.
- the flange 1 is, as already stated, preferably made of aluminum, but may also be formed from a glass fiber reinforced plastic.
- the recesses 3, 3 'extend alternately from one and the axial side of the disc-shaped region 1' to not quite to the axial center thereof, so that between the recesses 3, 3 'is a continuous, circumferential on the circumference annular web 9 is formed.
- the recesses 3, 3 'extend primarily in the axial direction a, that is, they are kept flat, so that their axial extent is preferably greater than their extension in the radial direction.
