A cell for gas generation is provided, particularly for the operation of a lubricant dispenser. The cell has two electrodes to be connected to a circuit containing a power source, and an aqueous electrolyte fluid located between the two electrodes, containing an azide having the formula XN, for electrochemical generation of a gas containing nitrogen (N). The electrolyte fluid contains a magnesium salt as an additive, for chemical binding of hydroxide ions that are formed during the electrochemical reaction.

Cell for gas generation

The invention relates to a metering device for lubricant having a lubricant reservoir (), a piston (), which is arranged on a threaded spindle (), within the lubricant reservoir and a drive head, which has a drive shaft () connected to the threaded spindle () and an electromechanical drive () for actuating the drive shaft. The drive shaft () contains a lubricant passage duct () which opens into the lubricant storage space of the lubricant reservoir. A ram () is inserted into the lubricant passage duct () of the drive shaft, said ram having an axial bore () with a nonreturn valve () on the inlet side, and also a ram head () which is arranged in a rotationally fixed manner and is loaded by a compression spring (). The ram head () bears under the effect of the compression spring () against a control surface () of the drive shaft (). The control surface () and the associated contact surface of the ram head () are designed as slotted-guide surfaces which, when the control surface () rotates, bring about stroke movements of the ram (), said movements conveying lubricant through the bore () in the ram () to a lubricant outlet at the end of the ram.

Metering device for lubricant

A device for supplying several lubrication points on machine parts with a lubricant, comprising an electromechanical lubrication dispenser and a distribution device coupled to a lubricant outlet of the dispenser. The distribution device has a housing, a cylindrical hollow distributor body or tube which is mounted to rotate about a vertical axis. There is also a fixed cylindrical sleeve that surrounds the distributor body, forming a seal. The distributor body has an opening at the top for allowing the lubricant in, and has at least two distributor bores disposed on the circumference but offset axially from one another. Each of these distributor bores has a corresponding opening bore in the distributor sleeve that is assigned to it. This distribution device also has an electric motor drive that has a running path control that has a switch that functions electromechanically or in a contact free manner. This drive has a switch that stops the rotational movement in different release angle positions that can be variably established.

Device for supplying lubricant to several lubrication points on machine parts

A lubricant dispenser comprising a housing, a lubricant supply container, a plunger, a telescopic hollow spindle, and an electromechanical servo-drive for changing the length of the telescopic hollow spindle. One end of the telescopic hollow spindle is fixed on the housing. With its other end, the telescopic hollow spindle cooperates with a plunger containing a passage opening for lubricant. The telescopic hollow spindle has a lubricant passage channel in which at least one check valve is arranged on the inlet side. The telescopic hollow spindle alternately carries out setting strokes of different lengths that increase or reduce the length of the spindle. The setting strokes are coordinated with each other so that with a setting stroke of the telescopic hollow spindle increasing the length of the spindle, a preset amount of lubricant displaced by the movement of the plunger enters the lubricant passage channel through the opening check valve.

A self-aligning roller bearing includes an external ring with one curved external track, an internal ring with two curved internal tracks, two rows of rollers disposed between the external and internal rings, and a guide ring. The guide ring is located between the rows of rollers and is preferably configured as an circular annular disk. The guide ring has a rectangular cross section with the center line of the cross section running parallel to the bearing axis. The guide ring may also be dimensioned in such a way that the rollers are axially prestressed. The front faces of the rollers which face the guide ring are configured in a manner that the front faces only touch the guide ring at one point.

Self-aligning roller bearing

An antifriction bearing having one or two rows of rolling bodies has at least one guide ring guided on the outside ring race for guidance of the rollers and/or of the separator. The guide ring comprises two partial circumference ring segments which are arranged loosely between or adjacent one or each of the rows of rolling bodies and are held in form-locked manner in the spherical surface of the outer ring due to resilience of the ring segments.

Guide ring for roller bearing

To provide good cage guidance in a window cage for a preferable flangeless spherical roller bearing in order that the bearing might achieve higher loads, the cage includes two annular axially spaced apart ribs and transverse ribs that extend between the annular ribs and define cage pockets. At least one and preferably two and preferably opposite pockets of the cage are loading pockets. The annular ribs are radially outside the pitch circle of the bearing, but at the loading pockets, those ribs are recessed inward nearly on the pitch circle of the bearing and preferably outward thereof about the thickness of the rib material. The angle between the center of the loading pocket and the adjacent pocket is larger than the angle between the centers of other adjacent pockets to facilitate loading of the loading pockets.
