Abstract

Cylindrical rollers (3) of a linear bearing (1) are located in a flat cage (5) which is made from plastics. Each cage has three pockets (2) for the location of three bearing rollers. Grooves (5, 6) along the cage members are provided to link bearing elements with wire rings (8) of rectangular shape. In this manner a number of cages can be linked together to form a bearing for a circular location. By using plastic hooks (9) the cages can be joined side by side to form parallel rows of linear roller bearings. The wire rings are a snap fit in the grooves, which close around the links due to the resiliency of the plastics.

Description

Rollen-Flachkäfig für Schlitten- und Tromrn ellagerungen Die Lßrfindung betrifft einen aus aneinandergereihten Teilstücken bestehenden Flachkäfig für die Lagerung von hin- und herbewegten Iaschinen- oder Apparateschlitten und für die Lagerung von langsam umlaufenden oder Schwenkbewegungen ausführenden großen Trommeln.Flat roller cage for slide and drum bearings The solution relates to a flat cage for the Storage of reciprocating machine or apparatus slides and for that Storage of slowly rotating or swiveling large drums.

Für geradlinige Bewegungen über Führungsbahnen sind mit stollen oder Nadeln bestückte Flachkäfige bekannt, deren ein oder mehrere Wälzkörper aufnehmende Teilstücke durch angeformte Verklammerungsmittel miteinander verbunden sind. Diese meist aus Kunststoff bestehenden Flachkäftge haben den Nachteil, daß insbesondere bei längeren Führungsbahnen die Verbindungsstellen starken Beanspruchungen unterliegen, wodurch es zu Längenveränderungen des Käfigs bis zum Auseinanderreißen der Verbindungsstellen kommt. Für lange Führungsbahnen sind auch einteilige Stahl- und Aluminium-Flachkäfige bekannt, die vorzugsweise als Band hergestellt und auf jede verlangte Länge zurechtgeschnitten werden. Diesen Bauformen haftet der Mangel an, daß sie nicht universell verwendbar sind.For straight movements over guideways, cleats or Flat cages fitted with needles are known whose one or more rolling elements receive Sections are connected to one another by molded clamping means. These mostly made of plastic Flachkäftge have the disadvantage that in particular in the case of longer guideways, the connection points are subject to heavy loads, which leads to changes in the length of the cage up to the rupture of the connection points comes. One-piece steel and aluminum flat cages are also available for long guideways known, which are preferably made as a tape and cut to any length required will. These designs have the defect that they cannot be used universally are.
