摘要:
Described is a flanged bearing for the radial support of shafts, the bearing having an external ring (1) with flattened zones (8) to which the flanges (2) are detachably or undetachably connected. Designed in this way, the flanged bearing is considerably easier to manufacture.

The invention relates to an apparatus and a procedure for mounting a bearing wheel journal box (6) in a supporting structure. The supporting structure consists of a supporter side plate (4) having a seating (21) for the journal box (6). The seating has an opening delimited by corners (23,25). On the periphery of the journal box (6) there is an area (12) of reduced thickness, in the region of which the outer measure (S) of the journal box is smaller than the distance (W) between the corners (23,25) of the seating (21), while at other points the outer measure (D) of the journal box is larger than said distance (W). The journal box (6) is inserted into the seating (21) by holding the reduced-thickness portion (12) against the edge (23) of the opening and then turned into a desired position in the seating (21).
摘要:
A nonseparable thrust ball bearing comprising a pair of races (1,2) spaced apart in the direction of axis of rotation, a plurality of balls (3) rollable between the races, and a connecting ring (4) rotatably interconnecting the inner peripheries of the races. The ring comprises a hollow cylinder portion (4a), and outer flanges (4b,4c) formed at the respective ends of the cylinder portion generally at a right angle therewith and in engagement with the respective races (1,2). The cylinder portion (4a) is fitted at one end thereof in the corresponding one of the races with a clearance formed therebetween, and the flange (4b) of the ring at said one end thereof is fitted in a cutout (5) formed in the corresponding race (1), with a clearance provided in the cutout around the flange.

Ensemble support à compensation thermique, pour un palier d'arbre, monté sur une paroi d'un logement en alliage de magnésium (10) comprenant une garniture (30) fait en un matériau dont le coefficient d'expansion thermique se situe entre le coefficient d'expansion thermique valable de l'alliage de magnésium et celui du support métallique (14, 16). Un goujon de support (18) est muni de deux moyeux (17, 36), l'un servant de support au palier (16) de l'arbre et l'autre servant de support à la garniture (30) qui, à son tour, est soutenue par la paroi du logement (10).
摘要:
Method for producing variants of a model range of bearing arrangements, wherein the model range has different variants of bearing arrangements, in particular which are assembled from a kit which has at least one shaft, one bearing and one flange part, wherein each bearing arrangement is assembled at least from a shaft (5), a bearing (3) and a flange part (1), wherein the shaft is mounted against the flange part by means of a bearing, wherein the flange part has recesses, in particular holes, wherein spring elements (2) are arranged in the recesses of the flange part for setting the bearing in a first variant, and the recesses of the flange part for receiving the spring elements are filled only with lubricant for storing lubricant in a second variant.
摘要:
A bearing cartridge for a rotatable shaft of a wind turbine comprising a shaft and a back-to-back tapered roller bearing arrangement coupled to the shaft. The bearing arrangement comprising a first bearing having a first outer ring, a first inner ring and a plurality of tapered rollers; and a second bearing having a second outer ring, a second inner ring and a plurality of tapered rollers. The bearing cartridge further comprising a gear located on the shaft between the first bearing and second bearing and a sleeve for supporting an axial load between the first and second bearings and having one or more apertures that expose the gear for coupling to an external gear.
