Definitions
- the invention relates to a bearing arrangement with a shaft having at least one bearing pin, wherein a needle bearing with a cage and needle rollers accommodated therein can be mounted on the bearing journal, and with an outer ring which is inserted in a machine housing.
- Object of the present invention is therefore to eliminate the disadvantages of the known embodiment described above and to facilitate the assembly. This should be done easily and inexpensively.
- the object of the invention is achieved in that the cage has at least on one side axially adjacent to the needle rollers a Montagefase or Anphasungs institute whose radial extent decreases with increasing distance to the needle rollers. This creates an approximately conical ramp on the cage, so that lifted when inserting the shaft into the outer rings of the cage together with the needle rollers and the coaxiality between the outer ring and cage is made.
- the outer ring at least at one, the mounting direction facing side has a chamfer, which widens towards the edge of the outer ring out.
- the cage has at least on one side an outboard and empty pockets and that the outboard and / or the webs are formed between the empty pockets as Montagefase or Anphasungsiata. This results in a longer Montagefase and thus a smaller pitch, so that the assembly is further simplified.
- the cage is advantageously made of a plastic material and designed to be radially expandable, so that an easy mounting of the cage with the needle rollers is also given when the bearing journal is at least partially radially reinforcedgenom- opposite adjacent shaft sections.
- the expandability is facilitated by the cage having a separating slot aligned parallel to the axes of the needle rollers, the ends of the cage having matching fasteners.
- the ends can be connected to each other after placement of the cage on the journal, z. B. by means of hooks attached to each other. But it can also be provided other fasteners, z. As a lock or clips.
- Figure 1 is a perspective view of a bearing with outer ring, needle rollers and a partially inserted into the outer ring cage.
- Figure 2 sections through an outer ring and a cage with needle rollers at the beginning of assembly
- Figure 3 is a perspective view of a bearing similar to Figure 1;
- Figure 4 shows a section through a bearing in mounted position.
- 1 denotes an outer ring of a roller bearing, in which a cage 2 can be used, which has recesses for needle rollers 3.
- the cage 2 empty pockets. 4 on, which are separated by webs 5, wherein the webs 5 extend from an inboard 6 to an outboard 7 and connect them together.
- a Montagefase 8 is mounted, which tapers conically from the inboard 6 to the outboard 7.
- the inboard can be included in the Montagefase 8, so that the chamfer already begins next to the needle rollers 3.
- the cage 2 is raised at horizontal mounting of the shaft in the machine housing, not shown on the Montagefase 8 through the outer ring 1, so that a centering of the cage 2 and substantially also of the needle rollers 3 in the outer ring he follows.
- the outer ring 1 has an outwardly widening chamfer 9, so that upon further insertion of the cage 2 into the outer ring 1 according to FIG the needle rollers 3 in the cage 2 slightly lowered needle rollers 3 are still raised and introduced into the outer ring 1.
- the cage 2 has, as can be seen in Figures 1 and 3, a separating slot 10, whereby the cage made of a plastic material slightly widened and over adjacent shaft portions larger radial Warre- ckung or radially directly on a bearing pin, not shown a mass balance shaft can be pushed.
- the ends of the cage 2 can be fastened to one another after enclosing the bearing journal by means of the fastening elements 11 shown in FIGS. 1 and 3, in order to ensure a dimensionally accurate enclosure of the cage 2 around the bearing journal.
