Description

The invention applies to a bearing structure, in particular Tapered roller bearings with races baw »sleeves«

With most known bearing cracks between the individual Parts of the bearing exact tolerances are adhered to, so that the assembly and disassembly of the parts large.VU-hen and difficulties required in addition to these. Kachteile are the conventional bearings because of their difficult Build expensive to manufacture.

The main purpose of the invention is therefore to provide a bearing To create a significantly simplified structure that lighter and it can be installed and removed faster than it is in the middle of the house order is cheaper "

Another purpose of the invention is to create a bearing in which no support rings are required _e

According to the invention, this is achieved by a. Tapered roller bearings this is characterized by an annular inner sleeve and an annular outer halo, both toaiaeh shaped are, by an anaaiil at the same distance from each other arranged conical shapes between the inner and the outer sleeve, ▼ on each of which held by a cage -wirä »where di © Inner and outer hulls correspond to the cone of these Tapered rollers are tapered and the inner sleeve turned outside at both ends to form a n & ea Edge bent outwards, as well as by a support ring, - the in the inner corner part of that edge part a » set that on the end part of the inner cover with the greater DurohmeβΒ9Γ is »with the outer bulee on the End part with the smaller diameter to form a edge part turned inwards is bent inwards » the inner end surface of the inwardly turned edge part »

The outer sleeve abuts the outer end surface this outwardly rotated hand is arranged, which is formed at the end part of this inner IRilee with the smaller diameter, so that calibrated between these butting The circumferential end surface of the two sleeves creates a seal

This is further achieved by a tapered roller bearing, etc. in l "t composed by an annular inner ifülse and an annular outer sleeve, both of which bind conically shaped and aue thin steel plate with each other by a number of equally spaced conical rollers zr / ieehen dor inner and the outer sleeve, each of these tapered rollers being held at the end with the smaller diameter by a cage which has an inwardly curved edge portion for its purpose, and wherein the inner and outer sleeves conform to the tapered rollers of the tapered rollers inner sleeve is bent outward at its end part with the larger diameter and then inward so as to form a U-shaped Druckaufnähmeteil, the inner sleeve is bent outward at its end with the smaller diameter, so a small edge part to form and the outer sleeve bent inwards at its end with the smaller diameter en let, in order to form such an inwardly curved edge part «

In Piguren 1 to 3 iai; A tapered roller bearing according to the invention is shown as an annular outer sleeve 1 and an annular inner sleeve 2, which have different cone sizes the annular sleeves 1 and 2 are «. As shown in FIG. F, the annular sleeve 2 is bent outward at its opposite ends, so that aioh band parts 4 and 5 form. The edge part 4 at the iinüe iait the larger diameter of the inner annular tube 2 has a greater width than the other edge part 5 at the end with the smaller diameter of the inner sleeve 2 _O Dieeor edge part 5 is designed so that it is easily removed from the / inner sleeve 2 protruding outwards In the inner part of the circular part, a support ring 6 is inserted intermittently.

In these embodiments according to the invention, in which the conical slope of the outer and inner annular sleeve corresponds to that of the tapered rollers lying between them, this cell can be easily and simply assembled. In addition, the Konuefora allows the

differ slightly, if one takes into account that the taper of the inner side wall of the inner sleeve easily leads to a change in the wall thickness between the end with the larger and the smaller end with the smaller diameter of the sleeve ". A total difference in the inclination of the cone does not call for revenge parts, but leads to easier production. "In this way, the turning strength of the outer sleeve set on part A with the larger diameter can be a little larger than on part B with the smaller!
