Embodiment Construction

[0012] figure 1 and figure 2 The shown grease cartridge 1 is specially designed for a vertical thrust bearing of an open-end spinning rotor, of which there are several in an open-end spinning machine. In addition to the grease cartridge 1 shown, a cooperating rotor shaft 2 and a thrust bearing 3 as well as a bracket device 4 for clamping the grease cartridge 1 are indicated by dotted lines.

[0013] The grease cartridge 1 comprises a substantially cylindrical housing 5 with a grease chamber 6 containing grease. There is a thrust bearing ball 7 installed in the grease chamber 6, the ball is originally a part of the grease cylinder, when the rotor shaft 2 is running, it is supported by the ball, and the thrust bearing ball 7 itself is supported by the bolt type opening. Grooved thrust bearing 3 supports.

[0014] The housing 5 has a rear face wall 8 which provides a passage opening 9 for the screw-type thrust bearing 3 . Arranged on the front side of the grease cartridge 1 ...

Abstract

An exchangeable lubricant cartridge for a step bearing of an open-end spinning rotor is disclosed. The lubricant cartridge comprises a chamber containing lubricating grease in which a step bearing ball is arranged. A bore hole is provided for a rotor shaft at a front housing wall of the lubricant cartridge, while at a rear housing wall an entry bore hole is provided for a thrust bearing. For the purpose of facilitating assembly, the housing is divided into a first housing section comprising the front housing wall and a second housing section comprising the rear housing wall.

Description

technical field [0001] The invention relates to a grease cartridge for the thrust bearing of an air spinning rotor, which is provided with a substantially cylindrical casing with a grease chamber containing the grease and with a Vertical thrust bearing balls and a rear housing wall defining a grease chamber, and a front housing wall and an intermediate wall, wherein the rear housing wall has a passage hole for the thrust bearing, and the front housing wall has a hole for the rotation The first through-hole of the cup shaft and the intermediate wall have a second through-hole for the rotor cup shaft to lead to the grease chamber. Background technique [0002] The prior art of this type of grease cartridge is first published in German patent DE 198 17 911 A1. This known grease cartridge is designed together with the vertical thrust bearing balls as a disposable component, i.e. after the grease is used up, the grease cartridge is replaced with a new cartridge containing fresh ...
