The invention relates to a technique for lubricating various machines, in particular, machines, to each point of which a certain dose of lubricant must be supplied.

Designs are known for lubricating devices that perform this function, for example, a multipoint lubricator, containing rotating dispensing and freely moving dosing devices C

The disadvantage of these devices is the limited ability to change the number of taps due to the design complexity of introducing additional metering elements.

One-line and two-line lubricant feed spruces are known to Tayu, which contain distribution-dispensing or distribution and dispensing spools, forming end and dispensing chambers with lids, the lubricant from each of which is discharged in one outlet.

However, in order to increase the number of taps, the feeder in this case is required with an increase in the number of spools in it

A single-line sequential feeder is known, consisting of a series of distribution-metering spools installed with the possibility of reciprocating

displacement in a housing made in the form of separate sections, forming, together with the housing covers, end dosing, chambers, parameters

which determine the dose of lubricant. The sequence in which the lubricant enters the outlets and the sequence of actuation of the spools is determined by the grooves on the spools and channels in the housing, by means of which the end dispensing chambers are alternately connected to the pressure line or outlet. In addition, one of

The distribution and metering spools can be equipped with a position sensor, made in the form of a rod connected to the spool and inserted outside through a seal installed in the lid, 3J.

The disadvantage of such a feeder is that the maximum number of elbows 3 from it is equal to twice the number of spools, since each of

two dosing chambers with a lid form them. An increase in the total number of taps from the feeder is achieved by pu-. the increase in the number of spools included in it, and the change in the ratio of dosage volumes to different outlets by changing the diameter and or the stroke of the spool. The presence of the position sensor rod changes the volume of the dosing chamber, and the presence of a seal in the cover creates the possibility of lubricant leaking as it is worn. In addition, the number of spools included in one feeder is limited, since the optimal size of the feeder is selected taking into account the tightening torque of the connecting rods, determined by the number of shims between the sections, and the losses determined by the length of the switching channels.

The aim of the invention is to increase the efficiency of equipment maintenance by increasing the number of islets from the feeder by sequential distribution of lubricant from one end metering chamber over several outlets, which allows reducing the size of the feeder without reducing the number of lubricant consumers.

The goal is achieved by the fact that the spool is equipped with means of stepping around its axis and positioning in extreme positions and with longitudinal channels for alternately communicating one of the end, metering chambers with one of the radial taps made in the housing, the number This feeder is equipped with a means of controlling the axial and angular positions of the spool.

In addition, the tool for stepping and positioning is made in the form of teeth with a one-sided bevel on opposite end surfaces of the spools and lids, forming toothed joints, while in each extreme position of the spool the teeth of one joint are in engagement, and the teeth of the other are not in the engagement and in the angular relation are displaced one with another.

In this case, the offset of the teeth in the angular ratio is half their pitch.

 In addition, to obtain a larger number of taps from one dosing chamber, the feeder is made in the form of two spools, in one of which, provided with a means of rotation around its axis and positioning in the extreme positions, an axial channel is located inside which the second spool is located.

It is advisable that the feeder be provided with a means of control.

The axial and angular positions of the spool, made in the form of an eccentric mounted permanent magnet on the spool and fixedly mounted magnetically controlled contacts, while the magnet in one of the fixed axial angular positions of the spool switches only one of the magnetically controlled contacts

In this case, it is necessary that the magnetically controlled contact controlling one fixed axial and angular position of the spool be connected to an external current source.

In the circuit of magnetic contacts, controlling each fixed axial and angular position of the spool, the signal devices are connected, and the free ends of the magnetic contacts and signal devices are connected to the external current source via collectors.

It is advisable to use LEDs as a signaling means in the feeder.

I, an AND section of FIG. 13; on Fig - section KK on Fig.

The single-line feeder consists of a body made of separate sections, input 1, workers 2-5 and end 6 connected through gaskets 7-11 and using studs 12 and nuts 13. In the working sections there are 17 spools, the movement of which is limited by lids 18-25. Through all sections and gaskets, except for the end section 6, the central channel 26 passes and channels 27 and 28 pass through sections 2-5 and gaskets 8-10. In addition, channels 29-32 and taps 33 and 3 are made in the working sections . The lateral surfaces of the spools and 16 are made with longitudinal channels 35 and 3b. In the gaskets 8 and 9, besides those mentioned earlier, channels 37 and 38 are made, and in gaskets 7 and 11, channels 39 and lO and 1 and. The sensor for the axial and angular positions of the spool includes an eccentrically located permanent magnet 13 on the spool and a stationary magnetically controlled contact. A constructive embodiment of the cover of the working section with a multi-position sensor for the axial and angular position of the spool with signal means includes an eccentric permanent magnet 3 on the spool 3 fixed magnetic contacts t, collectors iS and i 6 and LEDs 7. The dual-circuit feeder of FIG. consists of a housing 8 with inlets and 50, taps 51 and 52, channels 53 and 5, distribution spool 55 with longitudinal channels 5b and 57, dosing spool 60 forming end dosing chambers 61 and 62 with covers 58 and 59. Moving the distribution 55 liter valve spool is limited to lids 63 and b. The feeder works as follows. The lubricant under pressure is fed through the inlet to the channel 2b and through the grooves of the spool 17, the channels 32 of section 5, the channels 2.28 and 29 of section 2 goes under the left end of the spool 1. The latter moves to the right, and the lubricant from under its right through the channels 30 of section 2, channels 40, 27, and 31 of section 5 and the grooves of the spool 17 are displaced into the outlet 33 of section 5 and the grooves of the spool 17 are displaced into the outlet 33 of section 3. At the end of the removal, the spool 1, due to the interaction of the teeth on the end face and the lid 18 is rotated to a predetermined angle, and its middle proto Coy said right end face of the spool chamber 15 through the channels 32 and channel sections 2 and 3 38 3 10 sections with the channel 26. The slide 15 is moved to the left. The lubricant from under its left end through channels 29 of section 3, channels 37 and 31 of section 2 and longitudinal channel 35 of spool 1 is forced out into one of the outlet apertures 3 of section 2. In this way, all the runner spools in one place and then in another direction, and their cycle of operation is repeated as long as the lubricant under pressure is fed into channel 2b. At each forward and reverse stroke of the spools W and 1B, they turn around their axis in extreme positions fixed along the axis and angle, through channels 35 and 3B alternately communicate with the metering end cameras of spools 15 and 17, respectively, one of the outlets of the feeder 3, as spools 15 and 17 go, a dose of lubricant is supplied. An eccentric permanent magnet 3 on the spool can occupy in space as many fixed axial and angular positions as the spool has, and if the magnetically controlled contact f is fused so that it switches only in one of the possible fixed axes and the position of the spool, the external electric circuit connected to it will receive a signal that the feeder has completed the cycle of operation. This signal can be used for. control and operation of the feeder. The multi-position axial and axial position of the spool with the signal means of FIGS. 8 and 9 work as follows. In each of the axially fixed spool positions, an eccentric permanent magnet switches only one of the correspondingly controlled Mcii contacts, which closes the electrical circuit of the LEDs 7, which are powered from an external source through collectors and 6. Thus, the glow one of the kj LEDs corresponds to only one fixed position of the spool, which facilitates troubleshooting in the event of a power supply failure. The sequence and principle of operation of the feeder shown in figures 11 and 12 are similar to that described. A feature of this version of the feeder is that the end metering chambers of both spools serve in pairs a lubricant to each of the water, i.e. The dose of the lubricant flowing into each mercury is determined by the sum of the parameters of the end chambers of the two spools. This variant of the feeder possesses more technologically wide possibilities for obtaining a large number of radial taps from one dosing chamber. Dual main feeder 13 -1 works as follows. The lubricant under pressure is fed through inlet E (the inlet 50 is unloaded from pressure K moves the spool 55 to the lower position and enters the dosing chamber 6l through the channel 53. The spool 60 moves downwards and the lubricant from the dosing chamber 62 is forced out through the channel 5, the groove of the spool 55 and the longitudinal channel 57 and enters one of the outlets 52. Then the lubricant is supplied under pressure through the inlet 50 while the inlet E is unloaded from the pressure, moves the spool 55 to the top its position and through channel 5 enter the metering chamber 62. The spool 60 is rewound upwards, and the lubricant from the metering chamber 61 through the channel 33 of the spool 55 and the longitudinal channel 56 enters one of the outlets 51. At each forward and reverse stroke the spool 55 rotates around its axis due to the interaction of the teeth at its end and covers 63 and in extreme positions fixed along the axis and angle through the longitudinal channels 5b and 57 alternately communicating the dosing chambers 6T and 62, respectively, with one of the taps 51 and 52. Thus, apply ii a feeder spool to the stepping rotation about its axis and positioned at the extreme positions of the number of taps has increased without increasing the total number of spools, incoming into the feeder, which reduces the complexity of manufacturing and metal, reduces the size of the feeder. The use of a combination of rotary and non-rotary spools in a single-line feeder allows for a different ratio and a more uniform supply of lubricant doses to the outlets during the full cycle of its operation. The use of means of controlling the position of the spool without a sealing element in the feeder increases its reliability and efficiency, by eliminating wear of the rubber seal and external lubricant leaks, automates the lubricating process and facilitates troubleshooting in the system.
