摘要:
The present invention relates to a spindle device that supplies a prescribed amount of a lubricant agent intermittently or continuously from a lubricant supply device (3) to a rolling bearing (2) via a supply pipe (4), wherein the lubricant includes a lubricating oil and wax and, when a liquefaction point, which is a prescribed temperature within a temperature range of 10-70 °C, is used as a boundary, assumes a liquid state when the liquefaction point is exceeded and assumes a semisolid state when at or below the liquefaction point, and the lubricant is transported from the lubricant supply device (3) in a semisolid state via the supply pipe (3), and is changed to a liquid state before the rolling bearing (2) and caused to flow into the bearing interior.

A greasing mechanism (1) for a main electric motor of a vehicle includes a greasing tube (10) that is filled with a semi-solid lubricant and has an indicator member (13) within the greasing tube (10). The indicator member (13) has a specific gravity that is smaller than that of the semi-solid lubricant and moves in a greasing direction from a first position 1 due to pressure of the semi-solid lubricant during greasing. The greasing mechanism (1) includes a retaining part that has a shape that stops at a second position the indicator member (13) moving during greasing. An indicator window (14) arranged in a portion of the greasing tube (10) including the second position is formed from a component that is at least partially transparent to visible light.
摘要:
A lubricant supply device that reliably removes air from lubricant such as grease and supplies the grease to an object of lubrication. An air detection sensor that detects air is disposed in a grease introduction hole of a grease transporting path. Grease supplied by a pump passes through the grease introduction hole, a chamber divided by a spool and a grease discharge port, and is introduced into the lubricated parts of a machine. If air in the grease is detected by the air detection sensor, a controller drives a switching valve, moves the spool by pressurized air, and connects the grease introduction hole to an air exhaust port. The air mixed in with the grease is then expelled from the air exhaust port. When the air detection sensor no longer detects air, the controller switches the switching valve, returns the spool to its original position, and discharges grease from the grease discharge port. The lubricant supply device detects and removes air that is mixed in with the grease just before the grease is introduced into the lubricated parts of the machine, and therefore can remove the air more reliably.

To avoid break-downs by excess feeding of a lubricant leading to unacceptable rise in temperature in bearing housings (1) it is suggested to apply opposite the feeding device (16) in an annular space or chamber (8) a trough-like receptacle (18) suitable to receive an excess of lubricant. The receptacle (18) consists of two parts (19, 19′) that can be pushed to each other from opposite sides around the shaft (2) in said chamber (8) to form said receptacle (18).

摘要:
The lubrication injector comprises a housing (14) and a translating metering body (16) axially moveable with respect to said housing and provided with a lubricant supply channel (36a). The injector further comprises at least one translating intermediate piston (20) radially interposed between the metering body (16) and the housing (14) and axially moveable with respect to said housing, said intermediate piston (20) carrying the metering body (16). The intermediate piston (20) is mounted slidable axially on the metering body (16). The intermediate piston (20) and the metering body (16) delimit at least partly a metering chamber (48) for a lubricant in communication with the supply channel (36a) of said metering body.

摘要:
A description is given of a filling system for the metered delivery of a lubricant (1), comprising a container (2) for receiving the lubricant (1), wherein a rod (3) interacts with the container (2), is mounted movably with respect to it and forces the lubricant (1) out of an outlet opening (4) arranged in the container (2). The invention also relates to cartridges for use in the filling system. One of the underlying objects of the invention was that of providing a filling system which can be supplemented by simple workshop means and enables the operator to fill up a lubricating system in a vehicle effortlessly within a short time. This object is achieved by a filling system in which the rod (3) is rotatably mounted with respect to the container (2) and turning of the rod (3) in a predetermined direction of rotation brings about a reduction in the storage volume (5) in the container (2) or a handheld device (10) and in which the rod (3) has means (20) for establishing a rotationally fixed connection with an adaptable turning tool.
摘要:
Bei einer Vorrichtung zum Schmieren von sich mit ihren von Schmiernippeln gebildeten Abschmierstellen langsam entlang einer Linie bewegenden Laufrollen, Kettenbolzen u. dgl. ist eine Fettpresse (21, 22, 25, 26) vorgesehen, deren Schmierkopf (21) über eine Antriebseinrichtung (25, 26) an die Schmierstellen anstellbar und wieder rückstellbar ist, wobei wenigstens ein Lagefühler (31) für den Abschmierstellen in ihrer Lage eindeutig zugeordneten Teile der Laufrollen bzw. Kettenbolzen und eine Steuereinrichtung (30) vorgesehen sind, die in vorbestimmten Relativlagen der Abschmierstellen zur Schmiervorrichtung die Anstellung bzw. Rückstellung des Schmierkopfes (21) und die Betätigung der Fettpresse (25, 26) steuert. Um eine Abschmierung bei in ihrer Lage den Schmierstellen eindeutig zugeordneter Schmiervorrichtung und insbesondere bei genau auf die Schmierstelle ausgerichtetem Schmierkopf (21) zu ermöglichen, ist die Schmiervorrichtung auf einem Schlitten (5) angeordnet, der über Mitnehmer (19) entlang eines Schmierweges (11) an die Kette bzw. Laufrolle ankuppelbar ist und nach dem jeweiligen Abschmiervorgang in seine Ausgangs-Wartestellung zurückkehrt, wobei die Steuereinrichtung (30) während der Mitnahme des Schlittens (5) über den Schmierweg (11) den Schmiervorgang und die An- und Rückstellung des Schmierkopfes (21) steuert.
