Description

Split lightweight needle cage

The innovation is one of two semicircular parts existing needle cage for the connecting rod bearings of high-speed machines. The requirement for these cages is that they can accommodate the largest possible number of rolling elements in order to have a high load capacity achieve au; that they are easy, around the im The centrifugal forces that occur are kept low and that they are stable, even under the occurring at the highest speeds. charges still ensure a long service life.

The one mentioned! Claims can be made with a meet split steel profile cage, the according to the innovation, the following, well-known features are united in one}

a) The cage windows are sized so that two Find girls lying right next to each other in them;

b) the window dividers are divided into several, partly inside, partly outside of the pitch circle Sections running parallel to the axis of the cage and two inclined to the axis of the cage extending intermediate sections connecting the outer and inner web sections divided;

c) the two cage joints are in the area of diametrically opposed cage windows provided between two touching needles.

The drawing illustrates the innovation in FIG. 1 in a front view and in FIG. 2 in a side view, the upper half of the cage being cut and the lower half

Half of the cage is shown in view. Each cage half includes two closed on all sides window 1 on, in each of which two Mädeln 2 are taken immediately adjacent to one another, and two half cage window 3 at its ends. The half cage windows 3 are created after the closed cage ring has been manufactured by a saw cut which divides the closed cage ring into two equal halves, the parting lines being provided in the area of diametrically opposite cage windows.

The window dividers located between the windows 1 settle, like Pig in particular. shows, from two lateral sections 4 and ■ and a central section 6 and two obliquely to the cage axis sections and 8 made of amines. The web sections k _t 5 and 6 run parallel to the cage axis, the sections h and 5 being outside the pitch circle and the section 6 inside the pitch circle. The window dividers are connected to one another by two side rims 9 and 10, which extend radially over the entire height of the cage profile.

in the exemplary embodiment provided there no holding means for the needles are provided in the area of the window, in particular on the closed windows 1, however, it is readily possible to remove the edges of the window dividers so dimensioned and ausubildea that the! needles are held radially inwards and outwards.
