Definitions

• the present invention relates to an automatically dispensing lubricant or the like device according to the preamble of claim 1.
• a lubricant sleeve which has a lubricant container in which there is an expandable body which contains a device for electrochemical gas development which can be started at any time, the resulting gas being in the expandable body builds up a pressure by which it expands to a certain extent every day and thereby presses the lubricant out of the lubricant container into the lubrication point.
• the expandable body which contains the device consisting of a galvanic element and an electrolyte, is held in the lubricant container by a closure cap, which engages with its outer edge under the outer edge of the expandable body and thus closes it (DE-PS 1256001).
• the gas-generating element which is arranged in an insert which can be inserted into the container lid.
• the developed gas also collects in an expandable body that moves a piston or separating insert and thus expresses lubricant from the lubricant reservoir (DE-PS 2520241 and DE-PA 3644207.0).
• the expandable body is made of a membrane or the like, which is closed by a cover cap and fastened to the Schierstoffbeh lter in a complex manner.
• the expandable body consists of several parts, on the other hand, electrolyte fluid can escape, which can lead to damage and environmental problems.
• the object of the present invention is to provide a device of the type mentioned at the outset, for the smallest amounts of lubrication, for inaccessible locations with limited space and also for locations which have to be removed and checked in certain circumstances for maintenance reasons. The risk of leakage of electrolyte liquid should also be avoided.
• the system for electrochemical gas generation - it can be an electrolyte with an electrochemical element, an electrolyte and two or more electrodes which can be connected to one another by a circuit, a gas-generating compact cell consisting of electrolyte, anode and cathode, or one Corrosion element or chemical gas generator - in a one-piece, stretchable, gas-impermeable bag a closed, separately treatable gas generation system is created, the content (quantity) of which is tailored to the corresponding application unc - as stated in claim 2 - also to be promoted directly in the Carinthian region Medium arranged
• the device according to the invention requires only a small amount of space and can be replaced without major problems.
• the bag is expediently welded and thus requires no further measures for sealing.
• the bag can be arranged in a room separated by a separating device.
• a power source can be provided in the bag itself or outside the bag according to claim 6 or 7.
• REPLACEMENT LEAF In the case of an external power supply, for example by means of a battery, a switch for starting or stopping the gas generation and / or an adjustable resistor for regulating the amount of gas generated and thus the amount of lubricant in the circuit can be provided according to further features.
• the battery and possibly the switch and the resistor can be combined in one unit and can be designed to be detachable or detachable from the bag. In this way, the individual parts can be combined according to the operating conditions or exchanged in the event of a fault or exhaustion, without all parts having to be exchanged.
• This device can be arranged as a separate unit at the lubrication points, but it is also possible to mount it directly in the lubricant-filled spaces of bearings or bearing housings.
• control devices can be switched into the circuit, which regulates the gas generation and thus the amount of donation according to the desired criteria.
• Fig. 1 is a lubricating sleeve with an electrolyte arranged in a bag and an electrochemical element
• Fig. 2 shows a grease liner with an attachable attachment, which has a battery for gas generation.
• Fig. 3 shows a storage arrangement with a bag
• REPLACEMENT BL 1 consists of a container 1, which is closed at the bottom with a funnel-shaped base 3 to be fastened via a thread 2 in the machine part to be lubricated, with an outlet bore 4.
• a container 1 filled with lubricant 5 there is an expandable, gas-impermeable bag 6 which has an electrolyte 7 and a galvanic element 8.
• the bag 6 is closed by welding or the like. The gas produced in the bag 6 by electrolysis expands the bag 6 and thereby presses the lubricant through the outlet bore 4 into the machine part to be lubricated.
• two electrodes 10 and 11 separated by an insulator 9 are provided in the expandable, gas-impermeable bag 6, which are connected to contact pins 13 and 14 in the lid 15 of the container 1 via a flexible, possibly insulated wire 12.
• the contact pins 13 and 14 engage in the sockets of an attachment 17 receiving a battery 16.
• This attachment 17 is detachably formed from the container 1 and thus from the bag 6.
• a switch and possibly an adjustable resistor can be arranged, which is not shown in more detail here.
• a roller bearing 18 is seated on a shaft 19 and in a housing bore 20.
• the space 21 between the roller bearing 18 and the housing cover 22 is filled with lubricant.
• an expandable, gas-impermeable bag 16 with electrolyte and electrochemical element similar to that described in FIG. 1, is arranged, which expands when the compressed gas is generated and presses the lubricant into the roller bearing 18 .
