A bearing housing structure (101) comprises a support section (102) for supporting a bearing (117), a reception interface (103) for receiving lubrication grease, and grease channels (104-106) for conducting the lubrication grease to both sides of the bearing which are mutually opposite in the axial direction of the bearing. The bearing housing structure comprises exit conduits (107, 108) for allowing the lubrication grease to exit the bearing from the both sides of the bearing and a grease reservoir (109) for storing the lubrication grease exiting the bearing via one or more of the exit conduits. The bearing housing structure is capable of operating in different positions so that the axial direction of the bearing can be horizontal, vertical, or slanting.

An axle assembly that includes a housing assembly and a dipstick assembly. The housing assembly may at least partially define a cavity that receives a lubricant. At least a portion of the dipstick assembly may be removably mountable to the housing assembly and may include a fitting and a dipstick.

The invention relates to a lubricant dispenser comprising a storage container (1) filled with lubricant and a pump (2) which is connected to or can be connected to the storage container (1) and by means of which the lubricant can be pumped out of the storage container (1). The pump has a pump housing (3) with an inlet opening (4) and an outlet opening (5), a piston (6) which is movably guided in the pump housing (3) in a linear manner, and a drive (7) which acts on the piston (6). The pump housing (3) of the pump (2) is connected to or can be connected to the storage container (1), and the piston (6) can be raised or lowered cyclically by the drive (7) in order to pump a lubricant from the inlet opening (4) to the outlet opening (5). The lubricant dispenser is characterized in that the piston (6) is designed in a stepped manner with an upper piston surface (10) which delimits an upper displacement chamber (8) and a lower piston surface (11) which delimits a lower displacement chamber (9) and is reduced compared to the upper piston surface (10). The upper displacement chamber (8) adjoins the inlet opening (4) via a first valve (13), and the first valve (13) is loaded or can be loaded into a closed base position. A through-opening (12a, 12b) which connects the upper displacement chamber (8) to the lower displacement chamber (9) with the interposition of a second valve (14) is arranged in or on the piston (6), and the lower displacement chamber (9) transitions into the outlet opening (5) via an outlet channel (16). When the piston (6) is lowered as the result of a negative pressure in the upper displacement chamber (8), the first valve opens (for example against a spring force), and lubricant is suctioned out of the storage container into the upper displacement chamber (8), but the second valve (14) closes and lubricant is pushed out of the lower displacement chamber (9) into the outlet channel (16). When the piston (6) is raised, the first valve (13) closes, but the second valve (14) opens in the piston (6), and lubricant both flows from the upper displacement chamber (8) into the lower displacement chamber (9) and is pushed from the lower displacement chamber (9) into the outlet channel (16).

An automatic lubricator for lubricating an object. The lubricator includes a housing with a coupling section configured to couple with a lubricant container containing a lubricant. The lubricant container includes a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. An electric motor is configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action. At least one sensor is arranged within the housing and configured to provide a sensor signal indicative of a distance between the at least one sensor and the piston of the lubricant container, and a control circuitry configured to determine, based on the sensor signal, at least one lubrication parameter indicative of the at least one lubrication action.
