Description

The invention relates to lubricating devices and can be used in the lubricating systems of machine tools, forging equipment, etc.

The purpose of the invention is to reduce operating costs due to the impossibility of changing the dose of lubricant supply to friction units and reducing the standard size of manufactured feeders, as well as providing centralized control of the operation of the feeder and the lubrication system as a whole.

The indicated goal is achieved by that. that in the additional channels connected through the bore of the plunger with a tap, shut-off valves are installed, and control stops are located in the working cavities of the bore.

1 and 2 schematically depict a sequentially adjustable lubricating feeder.

The feeder consists of elements 1. 2, 3. in the bores of the housing 4, 5, 6. of which the plungers 7, 8, 9 are located. The bores of the housing of the elements 4.5, 6 are connected by the main channels 10, 11, 12.013, 14, 15, and in parallel The channels have additional channels 16, 17, 18. 19. 20, 21, in which shut-off valves 22, 23, 24, 25, 26, 27 are installed. On the plungers located in the bores of the housings, there are two symmetrical groove systems, each of which contains three grooves, the first extreme grooves 28.29, the second grooves 30. 31 and the third grooves 32, 33 on the plunger 7; the first extreme grooves 34. 35, the second grooves 36.37. third grooves of 38.39 plunger 8; the first extreme grooves 40, 41, the second grooves 42, 43 and the third grooves 44. 45 - on the plunger 9, connecting in the embodiment (see Fig. 1) with closed shut-off valves and turned out of the working cavities 46,47. 48, 49. 50, 51 regulatory 00

mi stops 52, 53, 54, 55, 56, 57, through the grooves of the plungers, channels with bends 58, 59.60, 60.61.62.63.

In the embodiment (see Fig. 2) with open shut-off valves and adjusting stops screwed into the working cavities, outlets through the grooves of the plungers are connected through additional channels.

The lubricant is supplied to the bores of the housing by an inlet channel 64.

The feeder works as follows: (see Fig. 1) supply of a full dose of lubricant.

Lubrication from the inlet channel 64 through the second groove 30 of the plunger 7, through the main channel 11 enters the working cavity 49 of the bore 5 of element 2 under the end of the plunger 8. The plunger 8, moving its second end, squeezes a dose of lubricant from the working cavity 48 along the main channel 10, the first extreme groove 28 in the outlet 58, the movement of the plunger 8 occurs until it stops against the end of the working cavity 48 of the bore 5 and moving the plunger 8 by the second groove 37 connects the inlet channel 64 to the main channel 12, through which the lubricant enters the working cavity 50 of the bore 3 and under end 9 and moving it displaces lubricant from the working cavity 51 through the main channel 13, a first extreme groove 35 in the outlet 61; the plunger 9, having moved its second groove 42 connects the channels 64 and 15, the lubricant enters the working cavity 47 of the bore 4 under the end of the plunger 7, moves it, displacing the dose of lubricant from the working cavity 46 along the main channel 14, the first extreme groove 40 the plunger 9 to the outlet 62. Moving the plunger 7 with a second groove 31 connects the input channel 64 with the main channel 10, through which the lubricant enters the working cavity 48 under the end face of the plunger 8, moving it and squeezing out the dose of lubricant from the working cavity 49 along the main channel 11, the first extreme groove 29 of the plunger 7 in the outlet 59; the plunger 8, having moved, connects the inlet channel 64 with the second groove 36 to the main channel 13, through which the lubricant enters the working cavity 51 of the bore 6 under the end of the plunger 9 and moves it, displacing from the working cavity 50 a dose of lubricant along the main channel 12 , the first extreme groove 34 of the plunger 8 in the branch 60; having moved, the plunger 9 connects channels 64 and 14 with its second groove 43, supplying lubricant under the end face of the plunger 7 into the working cavity

46, and moves the plunger 7, displacing the dose of lubricant from the working cavity 47 along the main channel 15 of the first extreme groove 41 of the plunger 9 into the outlet 63, lubrication cycle

begins to repeat.

The operation of the feeder with a reduced dose of lubricant supply (see figure 2).

The adjusting stops 52, 53, 54, 55, 56, 57 are inserted into the working cavities to the full

length, shut-off valves 22, 23, 24, 25, 26, 27 are open, grease from the inlet channel 64 to the working cavities 49,50,47,48, 51 and 46 enters through the grooves and channels 32 and 11; 39 and 12; 44 and 15; 33 and 10: 38 and 13; 45 and 14 and

expelled from the working cavities 48, 51, 46, 49, 50, 47 to the branches 58, 61. 62, 59, 60 and 63 through the channels and grooves 10, 16 and 28; 13, 19 and 35; 14, 20 and 40; 11, 17 and 29: 12. 18 and 34; 15.21 and 41.

Using the invention will allow

to ensure the regulation of doses of lubricant supply to friction units during operation of the feeder, which will significantly reduce operating costs, and will make it possible to reduce the standard size range

feeders, which will significantly reduce production costs, and also allows you to control the operation of the entire lubricant by the movement of one plunger, which will increase the reliability of the equipment.
