Description

  • Field of the invention
  • The invention relates to a bearing assembly comprising a bearing with an inner and / or outer ring, and a shaft which engages in the inner ring or engages around the outer ring, and a bearing axially securing the bearing locking ring.
  • Background of the invention
  • Often it is necessary to axially secure a bearing, be it a roller bearing or a plain bearing, on a shaft. Often this purpose, a circlip is used, which is slotted, so something can be bent or bent so that it can be pushed axially when sitting on the shaft inner ring on the shaft or inserted into the shaft outer ring also in the shaft. On the shaft side a circumferential groove is provided in any case, in which snaps the locking ring. It protrudes slightly radially, so that the respective bearing ring starts axially against it. In this case, the locking ring is arranged axially in front of the respective bearing ring. Consequently, axial space is needed about this security measure. This is accompanied by the fact that, after the shaft side, a corresponding groove, in which the snap ring snaps, is provided, the shaft always axially overshoot the camp something, so even at the closest possible arrangement of the bearing at the shaft end still something protruding, so also required additional space.
  • Summary of the invention
  • The invention is therefore based on the problem to provide a bearing assembly, which is improved in comparison and is constructed more compact.
  • To solve this problem is provided according to the invention in a bearing assembly of the type mentioned that a circumferential annular groove is provided on the inner ring or on the outer ring, in which the retaining ring is received, and that on the shaft a circumferential shaft groove is provided, into which the retaining ring, which is deformed when connecting the shaft to the bearing by the shaft and pressed into the annular groove, snaps.
  • In the bearing assembly according to the invention, the axial securing is quasi integrated into the camp, that is, the security level is located in the camp, but not seen axially before the camp. To make this possible, either on the inner ring when mounted on a shaft bearing or on the outer ring when inserted into a shaft bearing an annular groove is provided which is radially open. In this groove a locking ring is used, which can be pre-assembled. This is thus located radially projecting either on the inner ring or on the outer ring.
  • On the shaft itself a shaft groove is formed. Depending on whether the shaft is pushed into the inner ring or over the outer ring, the shaft groove is located on the outer lateral surface of the shaft or on the inner circumferential surface of a corresponding shaft bore etc. During assembly, the shaft is now either in the inner ring or over pushed the outer ring. In this case, the shaft inevitably runs against the radially slightly protruding retaining ring. With continued insertion movement of the circlip is elastically deformed by the shaft and pressed into the annular groove, that is radially widened when arranged on the inner ring, pressed radially inward when arranged on the outer ring. Upon further movement of the shaft relative to the bearing, the shaft groove enters the region of the securing ring, which automatically snaps into the shaft groove upon reaching the assembly position, since it is elastically deformed. He is then taken up both in the annular groove and the shaft groove, so that the axial securing of the bearing is given.
  • Since the retaining ring is arranged quasi in the actual storage level, it inevitably requires no additional axial space. Also inevitably shortens the length at which the shaft protrudes from the bearing solely due to the realization of an axial securing measure.
  • This offers the possibility of arranging the bearing thus close to the shaft end. It is only necessary for this purpose to form the shaft groove in the region of a shaft end. Finally, it is even possible to arrange the shaft groove and the annular groove on the shaft end or the inner or outer ring such that the bearing is substantially flush with the shaft end. Despite given axial securing consequently a secure arrangement of the bearing is possible directly at the shaft end.
  • As described, the corresponding deformation of the locking ring is obtained by the shaft, which engages with its shaft end on the locking ring. In order to easily allow this deformation, be it an expansion, be it a narrowing, is expediently formed on the shaft end, which is pushed into the inner ring or over the outer ring, an engaging on the retaining ring chamfer. Consequently, with this chamfer, the leading shaft end can engage under the securing ring on the inner ring or engage over the securing ring on the outer ring and correspondingly deform as a result of this chamfer, on which the securing ring rests when the sliding movement continues.
  • In this context, it is expedient if the securing ring also has a bevel acting on the shaft end, so that consequently two ramped chamfers accumulate on one another. Alternatively, it is of course conceivable to provide such a bevel instead of a chamfer on the shaft end only on the retaining ring. The function would be equally given.
  • The bearing assembly itself can be assigned to a wide variety of technical fields. An example of such a bearing assembly is a clutch release bearing, so a cover-fixed release bearing a clutch system. Especially in such coupling systems, a small axial and radial space is available, so that the securing mechanism according to the invention is advantageous. In general, the use of a bearing assembly according to the invention in all applications, in which due to the burden of the bearing and the small space available there is no room for the axial "standard backup" with the axially adjacent arranged locking ring.
  • Short description of the drawing
  • An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it:
  • 1 a bearing assembly according to the invention of a first embodiment, wherein the shaft is not yet connected to the bearing,
  • 2 the bearing assembly 1 with inserted shaft in contact with the circlip,
  • 3 the bearing assembly 2 with expanded circlip,
  • 4 the bearing assembly 3 in the mounting position with inserted in the annular groove and the shaft groove retaining ring, and
  • 5 an enlarged detail view of the axial securing of the bearing on the shaft.
  • Detailed description of the drawing
  • 1 shows a partial view of a bearing assembly according to the invention 1 on average. It is the bearing assembly 1 for example, a clutch release bearing.
  • The bearing arrangement 1 includes a rolling bearing 2 with an inner ring 3 an outer ring 4 as well as a variety of in a cage 5 picked up balls 6 , The outer ring 4 is from a disk 7 embraced, in turn, with a third object 8th connected is.
  • On the inside of the inner ring 3 is a circumferential ring groove 9 formed, which is open radially inwardly. In her is a circlip 10 arranged, which is open in a known manner at one point, so that it can be elastically deformed. The circlip 10 can before the actual assembly of the warehouse 2 on a shaft already in the annular groove 9 can be arranged after the outer diameter of the locking ring 10 larger than the inner diameter of the inner ring 3 , so that in the unloaded state of the circlip 10 always something in the ring groove 9 intervenes. The ring groove 9 is seen radially so dimensioned that the retaining ring 10 can be stretched so that it continues radially into the annular groove 9 turns, as will be discussed below.
  • The circlip 10 has in the embodiment shown at its edge directed towards the bearing edge a slight chamfer 11 on, which allows easier attack of the leading edge of a shaft end to the retaining ring 10 expand, which will be discussed below.
  • The bearing arrangement 1 further includes a shaft 12 , which is designed here as a hollow shaft. On this wave 12 is the camp 2 to arrange and set secure axially. In the bearing assembly according to the invention shown in the figures, the shaft 12 in the warehouse 2 So in the inner ring 3 inserted.
  • At the wave 12 is a shaft groove 13 on the outside of the shaft 12 formed, which is open radially outward. This shaft groove 13 is located immediately adjacent to the shaft end, which in the region of its outer leading edge a chamfer 14 having.
  • Starting from 1 showing the bearing assembly in a state in which shaft 12 and bearings 2 not yet connected, now becomes the wave 12 in the warehouse 2 So in the inner ring 3 pushed in, see 2 , During this insertion movement, the leading shaft end reaches its chamfer 14 in abutment with the circlip 10 , and there its bevel 11 , Now starting from 2 the wave 12 continue through the camp 2 pushed, so the chamfers glide 11 and 14 on each other. The circlip 10 will, see 3 , widened, it will continue radially into the annular groove 9 pressed. According to 3 it runs along the outside of the shaft 12 , while during further assembly the shaft 12 is pushed further through the camp. This happens until the assembly position according to 4 is reached. In this lies the shaft groove 13 congruent to the annular groove 9 , The elastically expanded circlip 10 When this position is reached, it automatically snaps into the shaft groove 13 one. In the assembly position according to 4 engages the circlip 10 consequently both in the annular groove 9 as well as in the shaft groove 13 a, from which the axial securing of the bearing 2 results. Because of this bilateral Nuteingriffs the camp can 2 do not move axially.
  • 5 shows in an enlarged detail view of the mounting position 4 , Within 5 the engagement area of the locking ring is pulled out again enlarged. While in this example both on the shaft 12 as well as on the circlip 10 a chamfer 14 respectively. 11 is formed, it is basically sufficient, only on the shaft 12 or only on the circlip 10 to form a chamfer. For already this is sufficient to slip the locking ring 10 on the shaft 12 to allow for expansion.
  • It can be seen in the embodiment shown, the shaft groove 13 very close to the end of the wave 12 educated. This leads, see in particular the 4 and 5 that the shaft 12 only a short distance from the inner ring protrudes. This means that the bearing can be arranged close to the shaft end or even flush with the shaft end and simultaneously secured axially. This means that by moving the security level in the area of the storage level a very compact, space-saving storage arrangement 1 can be realized. The same is of course possible with a backup over the outer ring, as described below.
  • Although the 1 - 5 show an embodiment in which the shaft 12 in the inner ring 3 of the camp 2 is pushed and the axial securing takes place from the inner ring to the shaft, it is also possible in principle, the bearing 2 over its outer ring 3 on a wave 12 secure axially. In this case, the shaft overlaps 12 the outer ring 2 , The outer ring 2 then would a corresponding annular groove 9 have, which is open to the outside and in a corresponding locking ring 10 would be included. The shaft in turn, which is designed as a hollow shaft or has a bore, etc., would on its inner circumferential surface a radially inwardly open shaft groove 13 exhibit. Also, either the circlip points 10 and / or the wave 12 on each edge a corresponding chamfer 11 respectively. 14 on to allow a slide. In this embodiment of the invention, however, the retaining ring 10 over the wave 12 deformed radially inward and into the annular groove 9 pressed the outer ring. With reaching the final assembly position, albeit in this case, the annular groove 9 and the shaft groove 13 radially superposed, snaps the elastically deformed locking ring 10 back out and reach into the shaft groove 13 one. Since he is also in both the ring groove 9 as well as the shaft groove 13 is received, in turn, an axial securing, but here on the outer ring 3 , given.
