Embodiment Construction

[0026] figure 1 A cross section of a lubricant pump 1 according to a first embodiment is shown. The lubricant pump 1 includes a lubricant reservoir 2 that stores a lubricant 3 such as grease or oil. The lubricant reservoir 2 includes a reservoir cover or top cover 4 that closes the upper end of the lubricant reservoir 2 and a follower plate 5 that follows the lubricant 3 liquid level. Due to gravity, the follower plate 5 facilitates the movement of the lubricant 3 towards the first and second reservoir outlets 6a, 6b, especially if the lubricant 3 is grease. Furthermore, a lubricant reservoir is mounted to the housing 7 of the lubricant pump 1 , wherein the housing 7 is closed by a bottom cover 8 . Housing 7 and bottom cover 8 and / or housing 8 and lubricant reservoir 2 may be integrally formed.

[0027]The lubricant reservoir 2 has in its center a preferably tubular inner part 9 sealed from the lubricant 3 , in which a motor 10 comprising a motor shaft 11 is arranged. The ...

Abstract

Disclosed is a lubricant pump (1) comprising at least one lubricant reservoir (2), a motor (10) comprising a motor shaft (11), where the motor (10) is configured to rotate the motor shaft (11) in clockwise and counterclockwise rotational directions, at least one pump element (13a, 13b) configured to provide a predetermined amount of lubricant (3) from the at least one lubricant reservoir (2) to at least one outlet (17a, 17b), wherein the lubricant pump (1) further comprises at least one freewheel (18a, 18b) mounted to the motor shaft (11) wherein the at least one freewheel (18a, 18b) is configured to cooperate with the at least one pump element (13a, 13b) in an engaged state if the motor shaft (11) is rotated in one of the two directions of rotation such that the at least one pump element (13a, 13b) provides the amount of lubricant (3), if the motor shaft (11) is rotated in the other direction of rotation, the motor shaft (11) is free to operate in an idle state such that the at least one pump element (13a, 13b) is idle.

Description

technical field [0001] The invention relates to a lubricant pump. Background technique [0002] Typically, machines having moving parts such as vehicles, excavators, etc. require lubricant to be supplied to the moving parts or other lubricant consumers or friction points in order to reduce wear at these parts and increase the operating life of the machine. In order to supply lubricant to different consumers or friction points, lubricant pumps are generally used, which supply lubricant according to time, for example at fixed intervals. However, different consumers are subject to different amounts of wear, ie there are high wear consumers and low wear consumers. For example, faster moving parts may require a higher supply frequency than slower moving parts. This may result in high wear consumers or friction points being under-lubricated, while low wear consumers or friction points may experience over-lubrication, thereby increasing the overall lubricant consumption.
