A lubrication system includes a progressive distributor that is configured to dispense lubricant to a consumer. The lubrication system also includes a control device and at least one sensor that is configured to determine at least one lubricant pressure inside the lubrication system. The control device is configured to receive measured values from the at least one sensor and to recognize a lubrication cycle based on the measured values and also to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison.

Lubricating system

A lubrication system includes a progressive distributor and at least one pressure sensor. The progressive distributor includes a housing block having a lubricant inlet, a plurality of lubricant outlets, a plurality of piston bores fluidically connected to the lubricant inlet, each of the plurality of piston bores having a first outlet bore and a second outlet bore, and a metering piston in each of the plurality of piston bores. Each of the metering pistons is displaceable in a respective one of the plurality of outlet bores to uncover either the first outlet bore or the second outlet bore. The pressure sensor is disposed at an inlet of the progressive distributor upstream of the metering pistons with respect to a lubricant flow direction and configured to determine a lubricant pressure.

Lubrication system

A device for outputting a future state of a central lubrication system includes at least one sensor for recording a parameter of the central lubrication system, a processing unit for processing the recorded parameter, determining a current state of the central lubrication system based on the processed parameter, and estimating a future state of the central lubrication system over a certain period of time based on the current state and stored data, and an output unit for outputting the future state of the central lubrication system.

A progressive distributor for lubricant includes a housing block having an inlet and a plurality of outlets and a plurality of metering pistons received in associated piston bores in the housing block. Each piston bore is associated with two lubricant outlet bores, and each metering piston is displaceable and configured to alternatingly release the one or the other lubricant outlet bore in order to dispense the metered lubricant amount to the lubricant outlet bore. The piston bores are fluidically connected to the lubricant inlet bore and to each other via connecting bores in order to transfer lubricant to the other piston bores. A dummy piston is disposed in one of the piston bores that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass passageway that fluidically connects two of the connecting bores to each other.

A lubricant injector includes a lubricant inlet, a lubricant outlet, a control piston and a metering piston. The control piston is configured to conduct lubricant from the lubricant inlet to the metering piston, and the metering piston is configured to pump the lubricant provided by the control piston to the at least one lubricant outlet. The metering piston includes a first metering chamber and a second metering chamber that are each connected to the at least one lubricant outlet. The lubricant injector further includes first and second lubricant channels, and in a first switching state of the control piston the lubricant inlet is connected via the first control space to the first lubricant channel and the second metering chamber, and in a second switching state the lubricant inlet is connected via the second control space to the second lubricant channel and the first metering chamber.

Lubricant injector

A lubricant pumping system includes a lubricant pump having a lubricant pumping space, a first seal configured to seal the lubricant pumping space, at least one signal detector, and a leakage detector for detecting leakage of a lubricant from the pumping space through the first seal and sending a signal to the signal detector in response to a detection of the leakage of the lubricant. The signal detector may produce a visual or acoustic output in response to receipt of the signal.

A progressive distributor includes a housing block with an inlet bore and outlet bores and first and second metering pistons in first and second piston bores. Each piston defines first and second annular workspaces and delimits first and second metering spaces at the ends of each piston, the first and second piston bores each having a central axis and being disposed one atop the other so that their central axes are parallel to each other and located in a central plane. Switching bores connect the metering spaces of the first metering piston to the workspaces of the second metering piston, and the switching bores are located on opposite sides of the central plane.

Progressive distributor

A switching device for alternately connecting a hydraulic drive of a lubricating pump to a pressure line and to a return line of a hydraulic circuit. The switching device includes first and second drive lines connected to the hydraulic drive, and pressure and return drive lines connected to the pressure and return lines. A switching valve is in fluid communication with the drive lines and is switchable between first and second switching states to connect the pressure drive line to the first drive line or to the second drive line. A plurality of hydraulic control lines control the position of the switching valve. The drive lines are configured to conduct a first volumetric flow of hydraulic fluid and the hydraulic control lines are configured to conduct a second volumetric flow of the hydraulic fluid different than the first volumetric flow.

Switching device and lubricating pump

A lubricating-grease pump includes a pumping chamber, a leakage accumulation chamber, a seal configured to substantially seal the pumping chamber from the leakage accumulation chamber, at least one outlet from the pumping chamber, and at least one leakage-recovery arrangement configured to guide a quantity of grease that has leaked from the pumping chamber into the leakage accumulation chamber back into the pumping chamber. The leakage-recovery arrangement may include a first passageway connecting the leakage accumulation chamber to a storage region, a second passageway connecting the first passageway to the pumping chamber and a spring-biased piston in the storage region.

A lubricant application device includes a base body configured to be mounted to an end surface of a gear. The base body includes a port configured to be connected to a source of lubricant and a holder for holding a lubricant applicator supported by the base body. A lubricant passage connects the port to the holder, and a lubricant applicator is mounted in the holder. The lubricant applicator is a coiled wire defining an internal passage for carrying the lubricant and may include a first length of coils with no axial spacing and a second length of coils that are axial spaced.

Lubricant applicator

A device for detecting a movement of a piston of a lubricant distributor includes a movable actuator including a first magnet element, and a movable indicator including a second magnet element. The actuator is configured to be moved from an initial actuator position to an end actuator position by a movement of the piston, and the actuator and the indicator are configured and disposed such that a repulsive magnetic force prevails between them such that the indicator is moved from an initial indicator position to an end indicator position by the movement of the actuator from the initial actuator position toward the end actuator position.
