場合によっては引っ掛かって動かなくなることもある。B. PRIOR ART A segmented cage of this type is known from German utility model application no. Provided in the roller bearing groove. The segments of the cage known prior to this utility model are held together by clamps that are pressed through the end-transverse webs. A disadvantage of this method is that the connections at the joint cannot be bent, since the clamps can only transmit weak bending moments and easily bend away from each other. In the case of continuous operation, the cage is deformed by the heating of the bearing, wears out at the inner race, and in some cases may become stuck and become stuck.

Means for Solving the Problem The above problem is solved in that the retainer has a longitudinal hole in which the pin is inserted, starting from the joint thereof and running through the lateral longitudinal ridges. . The pins are preferably grooved pins or clamping pins, which are pressed into the holes and, because of their large mutual spacing, have a high radial immobility;
Feed into the holder which is divided.

の場合には保持器は複数の有利には３つのセグメントに
より形式され、横方向ウェブは、下組立ての段階ですで
にセグメントの中に挿入されるころ状転動体のための案
内面及び鼻状係止部材を有する。In the case of large roller bearings with large diameters, e.g. over 150 mm, the cage is in the form of several, preferably three, segments, the transverse webs having a roller-shaped structure which is inserted into the segments already during the under-assembly stage. It has a guide surface for the rolling elements and a snout-like locking member.

止部材における湾曲半径は転動体の半径より大きく、（
例えば伝動装置ケーシングの走行面における非円形性に
より惹起される）ころ軸受の半径方向での転動体の移動
を可能にする。The guide surfaces and nose-like locks do not extend over the entire length of the rolling elements, but rather close to their edges in order to avoid wiping off the lubricating oil film in the area of maximum pressing pressure between the rolling elements and the oncoming track. It only extends to some areas. The radius of curvature of the guide surface and nose-like locking member is larger than the radius of the rolling element, and (
This enables a movement of the rolling elements in the radial direction of the roller bearing (caused, for example, by non-circularities in the running surface of the transmission casing).

密閉部材を備える。The cage, made of synthetic resin reinforced with fibers, does not deform under heavy loads and retains the rolling elements in the guideway. The inner ring can also be a transmission casing made of gray cast iron, which is reinforced in the roller shaft neck area. The cover liner of the roller bearing includes a sealing member that abuts the rope winding drum.

ーシングの完全な圧潰又は切断は防ぐことができる。If the bearing is installed in a lifting device in which there is a risk of the load falling in the event of damage, the reinforcement of the casing in the area of the roller bearing, in cooperation with the cover liner, forms an additional safety device. Even in the event of a complete bearing failure, complete collapse or shearing of the transmission casing can be prevented.

寿命を与える。In a further embodiment of the invention, a rolled elastic opening ring is inserted between the inner ring and the rolling element, the ring being V-shaped at the joint. Both ends of the joint have inclined surfaces to prevent movement of the rolling elements. The low cost elastic ring gives the bearing a longer life as if the rolling elements ran directly on the gray cast iron transmission casing.
