Abstract

The invention relates to the lubrication technique of machine tools and other machines and allows the functional possibilities of the lubricant feeder to be expanded. Between the working sections, of which at least one main group is formed, containing at least three working sections, there are distributors connecting them in one position with external control, the inputs of which are connected to the control channels of the previous working sections, and the outputs The subsequent chambers, and in a different position of the distributors, two of their inputs and outputs are connected to the minor sections - locked, and the rest are pairwise communicated with each other. The feeder operates in various combinations of sections involved in the work, which is determined by applying an external command to the distributors, and provides the possibility of volumetric dosing of the lubricant to several groups of points with different time-independent lubrication modes. 1 il. and S (L 00 S71 O 4; 4 4

Description

The invention relates to a technique for lubricating machine tools and machines, in particular, to supplying centralized sequential lubricating systems for volumetric metering of lubricant, where it is required to be supplied to several groups of points with different time-independent lubrication regimes.

The aim of the invention is to provide the possibility of volumetric dosing of lubricant to several groups of points with different time independent lubrication modes.

by changing the number of participants, 15 working sections 1 are locked up with them, and

sections in the work of the sections of the feeder by an external command.

The drawing shows the scheme of the proposed feeder.

The feeder consists of working sections 1-7 with control channels 8 and 9 and control chambers 10 and 11 and valves 12 and 13 with electromagnetic control and spring return to the initial position, which are installed, for example, between working sections 2-3 and 5-6 feeder respectively. The control channels 8 and 9 of the previous working section of the feeder are connected to the control chambers 10 or 11 of the subsequent working section of the feeder.

In this case, additionally installed distributors 12 and 13, which are in one of the extreme positions under the action of the spring, do not break this connection, since their inputs, to which the control channels of the previous working sections are connected, are connected to their outputs, to which the controls are connected. chambers of subsequent working sections. The working sections of the feeder have inlet 14 and outlet 15 and 16 channels. The valves 12 and 13 are equipped with electromagnets 17.

The feeder works as follows.

The lubricant under pressure is supplied to the input channels 14 of the working section of the feeder, from which it sequentially enters the control channels 8 or 9 communicated with the control chambers 10 or 11 of the subsequent working section. In this case, the dosing-distributing spool of the working section switches and the lubricant is displaced from the opposite control chamber of the subsequent working section into the outlet

more channels 15 or 16 of the previous working section. Thus, the feeder, when the valves 12 and 13 are in extreme positions under the action of a spring, works as a normal sequential feeder with seven working sections and for a full cycle of its operation, the lubricant enters each of the seven working sections . When the electromagnet 17 of the distributor 12 is turned on, the control channels 8 and 9 of the working section 2 and the control chambers 10 and 11

the control channels 8 and 9 of the working section 7 communicate respectively with the control chambers 11 and 10 of the working section 3, which is subsequent with respect to the working section 7 ,. The feeder continues to work as part of sections 3–7, as a sequential feeder from five working sections, and the lubricant does not enter the discharge channels 15 and 16 of the disconnected sections 1 and 2. When the electromagnet 17 of the distributor 13 is turned on, the working sections 6 and 7 are similarly disconnected. The control channels 8 and 9 of the working section 5 are communicated by the valve 13 to the control chambers 11 and 10 of the working section 3, respectively. working sections 3-5. When the electromnite 17 of the distributor 12 is turned off, the latter returns to its original position under the action of a spring, and sections 1 and 2 start up the feeder operation.
