Definitions
- the electrical machine with the features of the main claim has the advantage that the metallic sliding element on the one hand has high hardness, which greatly limits the wear of the sliding element, and on the other hand, this ensures a high dimensional accuracy of the sliding element, the storage is particularly reliable and therefore particularly durable.
- Advantageous developments of the electrical machine according to the main claim are possible through the measures listed in the subclaims.
- a particularly high degree of dimensional accuracy has been achieved by the sliding element.
- the sliding element is particularly easy to manufacture by having an annular shape. If the sliding element is connected to a generally tubular sleeve part, encapsulation of the slip ring space is again possible by means of this sliding element and its tubular sleeve part. The encapsulation of the slip ring space enables it to be sealed off from harmful environmental influences such as dust, moisture and moisture. According to a further embodiment it is provided that the sleeve part is connected to the slide ring by means of a connecting element arrangement. This connection element arrangement has the advantage that a reliable connection between the slide ring and the sleeve part can be represented in this way.
- a particularly favorable and reliable connection between the sliding ring and the sleeve member is achieved by a 'n by means of snap elements executed connector assembly.
- Another reliable method of reliably connecting the sleeve part to the slide ring is to injection-mold the plastic sleeve part onto the slide ring using a plastic injection molding process.
- FIG. 1 shows a partially abstracted exemplary embodiment of an electrical machine in a sectional illustration
- Figure 2 is a sectional view of an inventive
- the electrical machine 10 has, in addition to other parts, not shown and not essential to the invention, a shaft 13 which carries an electrically active rotor 16.
- the shaft 13 is held in a hub 22 made of a metal alloy, for example an aluminum alloy, by means of at least one bearing 19.
- the bearing of the shaft 13 in this hub 22 is designed as a so-called floating bearing point 25.
- This floating bearing point 25 allows an axial relative movement between the bearing 19 fastened on the shaft 13 and the hub 22.
- a sliding element 28 is inserted and fastened in the hub between the bearing 19 and the hub 22, the sliding element being made of metal.
- the sliding element 28 is fixed in the hub 22 by means of a press fit. It is provided that the sliding element 28 has a minimum hardness of 570 HV 10. As indicated, the hardness is measured according to Vickers hardness test method. The hardness should ideally be between 570 and 640 HV 10.
- the sliding element 28 is designed as a ring.
- FIG. 2 shows another embodiment of the sliding element 28;
- the sliding element 28 initially has the ring shape already mentioned and has a rotor side R and a slip ring side S.
- the sliding member 28 is connected with- a generally rohrför strength sleeve part 31 'that connects to the slider 28th
- the sleeve part 31 serves to surround a sliding contact device 34 in the electrical machine 10 and thus to protect it from harmful environmental influences.
- the sleeve part 31 is first connected to the sliding element 28 by means of a connecting element arrangement 37.
- This connecting element arrangement 37 includes, for example, a snap connection shown in FIGS. 3a and 3b, in which the sliding element 28 and the sleeve part 31 each have snap elements 40 which interact with one another.
- the sliding element 28 has on its slip ring side, on the one hand, an annular bead 43 and, on the other hand, thereon an annular groove 46 axially towards the rotor.
- the sleeve part 31 initially has a radially inwardly extending ring element 49, which is adjoined axially in the direction of the slip ring side by a radially outwardly extending ring groove 52.
- the sleeve part 31 and the sliding element 28 are consequently connectable in that the ring element 49 of the sleeve part 31 into the annular groove 46 of the sliding element 28 engages.
- the annular bead 43 engages in the annular groove 52 of the sleeve element of the sleeve part 31.
- the sleeve part 31 is injection molded onto a slide ring 28.
- the sliding element 28 as already shown in FIG. 3a, has positive locking elements.
- These positive-locking elements are, for example, the already mentioned annular groove 46 and the annular bead 43.
- a suitable connection between the sliding element 28 and the sleeve part 31 is achieved by at least partially encapsulating these two elements.
- the sleeve part 31 covers the sliding contact device 34 for powering the rotor 16 or ' . of the electrical machine 10 itself at least partially.
- an opening 55 is provided on the circumference of the sleeve part 31, into which an brush holder 58 can be inserted.
