Description

Technical Field

[0001] The present invention relates to the technical field of lubrication equipment, and more particularly to a chain lubrication system. Background Art

[0002] When a traditional chain is working, there is relative movement between the chain links, and the metal surfaces are in direct contact and friction. If there is a lack of lubrication during long-term operation, the chain links will wear out more, causing the chain to elongate, lose strength, or even break. Therefore, enhanced care is required to reduce the replacement rate.

[0003] In most cases, traditional chain lubrication systems apply lubricant while the chain is stationary. This typically involves periodic manual application of lubricant or a simple drip lubrication system. This makes it difficult to ensure even distribution of lubricant across the chain, and the lubricant dosage is also imprecise. This can lead to insufficient lubrication in some areas and excessive lubrication in others, impacting the overall performance and service life of the chain. Summary of the Invention

[0045] Chain lubrication system, see Figure 1-9 As shown, it includes: a base 100, a main body 200, a main shaft 300, a cam 400 and a piston rod 500.

[0046] The base 100 is equipped with a transmission assembly 110. The bottom surface of the base 100 is set to be flat so that it can be placed on the ground or mounted on other equipment. The transmission assembly 110 is used to connect the power source and the main shaft 300 to drive the main shaft 300 to rotate.

[0047] In this technology, the power source can be a common power structure such as an electric motor.

[0048] The main body 200 is fixedly assembled on the base 100 and has a first chamber 210 axially opened and passing through the upper and lower end surfaces of the main body 200 and a second chamber 220 axially opened and passing through the upper end surface of the main body 200;

[0049] The main body 200 is mainly fixed to the base 100 by means of screws or bolts, and the assembly method is simple; the main body 200 is made of high-hardness metal material.

[0050] Optionally, since the system provides lubricating oil, in order to better prevent oil leakage, a sealing ring can be added at the connection between the base 100 and the main body 200.

[0051] like Figure 4 As shown, the first chamber 210 is cylindrical, which enables the spindle 300 to rotate in the first chamber 210;

[0052] A plurality of oil outlet nozzles 230 are provided on the peripheral side of the main body 200, and the oil outlet nozzles 230 are subsequently connected to the places where lubricating oil is needed to realize the timed and quantitative output of lubricating oil; the present invention is a chain lubrication system, therefore, the oil outlet nozzles 230 can be connected to the oil receiving point of the chain through a pipeline (soft rubber hose, etc.), to realize the timed and quantitative output of lubricating oil to the chain, thereby improving the overall performance and service life of the chain.

[0053] The main shaft 300 is installed in the first chamber 210, and the lower end of the main shaft 300 is connected to the transmission assembly 110, and is driven to rotate by the transmission assembly 110; the part of the main shaft 300 in the first chamber 210 is cylindrical, and the diameter of the main shaft 300 is adapted to the inner diameter of the first chamber 210. The outer wall surface of the main shaft 300 and the inner wall surface of the first chamber 210 are infinitely close, but the main shaft 300 can rotate in the first chamber 210.

[0054] The cam 400 is located at the top of the main body 200 and is fixed to the main shaft 300 and rotates with the main shaft 300;

[0055] A plurality of piston rods 500 are installed in the second chamber 220, such as Figure 3 As shown, in this embodiment, six second chambers 220 are provided, and accordingly, six piston rods 500 are provided;

[0056] Alternatively, the number of second chambers 220 and piston rods 500 may be changed.

[0057] The upper ends of the piston rods 500 extend out of the second chamber 220 and are supported in the axial direction on the driving surface 410 of the cam 400. When the cam 400 rotates, the height difference of the driving surface 410 drives the multiple piston rods 500 to move up and down axially. The multiple piston rods 500 do not move up and down synchronously. Instead, some piston rods 500 move up while others move down.

[0058] The main body 200 is provided with a first oil passage 201 and a second oil passage 202 . The first oil passage 201 is connected to the first chamber 210 and the second chamber 220 . The second oil passage 202 is connected to the first chamber 210 and the oil outlet nozzle 230 .

[0059] The main shaft 300 is provided with an oil inlet channel 301 and an oil outlet channel 302;

[0060] The main shaft 300 rotates in the main body 200 to connect the oil inlet channel 301 with a first oil channel 201 ; and connect the first oil channel 201 with a second oil channel 202 through the oil outlet channel 302 .

[0061] Specifically, after the main shaft 300 and the cam 400 rotate a displacement, at least one of the piston rods 500 is in the ascending position, and at least one of the piston rods 500 is in the descending position. It should be noted that the piston rod 500 in the ascending position is supported at the highest position of the driving surface 410 of the cam 400; the piston rod 500 in the descending position is supported at the lowest position of the driving surface 410 of the cam 400;

[0062] At the same time, the oil inlet channel 301 is connected to the first oil channel 201 of the piston rod 500 in the ascending position, and the lubricating oil enters the second chamber 220 through the oil inlet channel 301 and the first oil channel 201 .

[0063] The piston rod 500 in the lowered position is connected to the oil outlet channel 302 on the main shaft 300 through the corresponding first oil channel 201, and the oil outlet channel 302 is connected to a second oil channel 202. Then, the lubricating oil in the second chamber 220 of the piston rod 500 in the lowered position is sent to the oil outlet nozzle 230 through the connected first oil channel 201, the oil outlet channel 302 and the second oil channel 202, and finally delivered to the designated place.

[0064] The other first oil passages 201 and second oil passages 202 that are not connected to the oil outlet passage 302 and the oil inlet passage 301 are approximately sealed by the inner wall of the main shaft 300 and are waiting to be connected when the main shaft 300 continues to rotate to the corresponding position.

[0065] In this way, the present technology can quantitatively pump lubricating oil into the second chamber 220 , and quantitatively pump the lubricating oil in the second chamber 220 to the designated oil outlet 230 , and finally deliver it to a designated location.

[0066] In one embodiment, the top of the piston rod 500 is threadedly connected to an adjusting bolt 510, and the lower end of the adjusting bolt 510 is supported on the driving surface 410 of the cam 400; the connection position of the piston rod 500 on the adjusting bolt 510 is adjusted to adjust the flow rate;

[0067] The top of the piston rod 500 is provided with a connecting portion 520. The connecting portion 520 is integrally formed with the piston rod 500, which can reduce the number of assembly steps. Of course, a separate structure is also possible. The connecting portion 520 is provided with a screw hole; the screw rod 511 of the adjusting bolt 510 is threadedly installed in the screw hole;

[0068] When adjusting the connection position of the piston rod 500 on the adjusting bolt 510 , it is only necessary to rotate the adjusting bolt 510 .

[0069] Since the lower end of the adjusting bolt 510 is supported on the driving surface 410 of the cam 400, rotating the adjusting bolt 510 to move the piston rod 500 upward or downward adjusts the depth to which the piston rod 500 can enter the second chamber 220, thereby ultimately achieving the purpose of regulating the flow rate;

[0070] The adjusting bolt 510 structure is adopted, which is easy to assemble and has a simple flow adjustment method.

[0071] The upper end of the piston rod 500 extends out of the second chamber 220 and is located on the top of the main body 200. It can be adjusted without disassembling the main body 200 or the piston rod 500, and the adjustment is convenient.

[0072] In this embodiment, six piston rods 500 are provided, and the upward and downward strokes of the six piston rods 500 are the same; optionally, the adjusting bolts 510 on any one or more piston rods 500 can be rotated to adjust the formation of part of the piston rods 500, so that the strokes of the six piston rods 500 are different.

[0073] Furthermore, the upper end surface of the cam 400 constitutes a driving surface 410, which is composed of a plurality of arc-shaped convex surfaces 411 and arc-shaped concave surfaces 412 connected at intervals. Therefore, when the cam 400 rotates, it can drive the piston rod 500 to move up and down;

[0074] The smooth transition between the convex surface 411 and the concave surface 412 allows the piston rod 500 to move up and down smoothly;

[0075] A recessed groove 240 is provided on the upper end surface of the main body 200 , and the cam 400 can be partially located in the recessed groove 240 to reduce the overall height of the chain lubrication system.

[0076] In one embodiment, multiple groups of oil nozzles 230 are installed on the peripheral side of the main body 200, and the multiple groups of oil nozzles 230 are arranged and distributed around the circumference of the main axis 300;

[0077] Each group of oil outlet nozzles 230 includes an upper oil outlet nozzle 231 and a lower oil outlet nozzle 232 , and the second oil passage 202 connected to the upper oil outlet nozzle 231 and the lower oil outlet nozzle 232 are parallel;

[0078] In the present technology, in a group of oil nozzles 230, the upper oil nozzles 231 and the lower oil nozzles 232 are distributed at different heights on the same vertical axis; and, the upper oil nozzles 231 of multiple groups of oil nozzles 230 are all at the same height, and the lower oil nozzles 232 of multiple groups of oil nozzles 230 are all at the same height.

[0079] Furthermore, the oil outlet channel 302 includes a first oil outlet channel 3021 and a second oil outlet channel 3022. The first oil outlet channel 3021 and the second oil outlet channel 3022 are opened on the peripheral side of the main shaft 300 and are arranged obliquely.

[0080] The first oil outlet channel 3021 connects a first oil channel 201 and a second oil channel 202 of an upper oil outlet nozzle 231;

[0081] The second oil outlet channel 3022 connects a first oil channel 201 and a second oil channel 202 of a lower oil outlet nozzle 232 .

[0082] Therefore, the first oil outlet channel 3021 and the second oil outlet channel 3022 have different heights.

[0083] The height of the first oil channel 201 is located on the center line of the connection line between the upper oil outlet nozzle 231 and the lower oil outlet nozzle 232 .

[0084] Furthermore, the oil inlet channel 301 includes: an oil inlet 3011 provided on the main shaft 300, and two oil outlets 3012 provided on the main shaft 300. The oil inlet 3011 is connected to an oil inlet nozzle 233 provided on the main body 200. The height of the two oil outlets 3012 is the same as the height of the opening of the first oil channel 201 on the inner wall of the first chamber 210.

[0085] Then, when lubricating oil is replenished, the two oil outlets 3012 are connected to the two first oil passages 201, and at the same time, the corresponding two piston rods 500 rise, and oil is delivered to the second chamber 220 through the oil inlet passage 301 and the first oil passage 201;

[0086] At the same time, the first oil outlet channel 3021 and the second oil outlet channel 3022 are connected to the first oil channel 201 and the second oil channel 202, respectively, so that the lubricating oil in one second chamber 220 is sent to the upper oil outlet nozzle 231 through the first oil channel 201, the first oil outlet channel 3021 and the second oil channel 202; and the lubricating oil in one second chamber 220 is sent to the lower oil outlet nozzle 232 through the first oil channel 201, the second oil outlet channel 3022 and the second oil channel 202;

[0087] like Figure 3 As shown, six groups of piston rods 500 are provided in the present invention. Each time the piston rods 500 are rotated by one angle, it is ensured that two groups of piston rods 500 are located in a high position, i.e., the convex surface 411, and two groups of piston rods 500 are located in a low position, i.e., the concave surface 412. In this way, when the above-mentioned rotation by one angle is achieved, oil is stored in the two second chambers 220, and the lubricating oil in the two second chambers 220 is sent to the oil outlet 230.

[0088] Furthermore, if Figure 6 As shown, the first oil outlet channel 3021 and the second oil outlet channel 3022 have different heights, and the first oil outlet channel 3021 and the second oil outlet channel 3022 are arranged obliquely, so that when supplying oil, an upper oil outlet nozzle 231 and a lower oil outlet nozzle 232 can simultaneously discharge oil;

[0089] As well as Figure 8 As shown, the oil inlet channel 301 includes: an oblique channel and a transverse channel. The lower end of the oblique channel is connected to the oil inlet nozzle 233, and the higher end is connected to the transverse channel; the two ends of the transverse channel are respectively the oil outlets 3012; after the main shaft 300 rotates to a position, the two oil outlets 3012 are respectively connected to the two first oil channels 201 to supply oil to the second chamber 220.

[0090] Further, if Figure 8 As shown, the main shaft 300 is provided with a circle of grooves at the position of the oil inlet 3011, so that the main shaft 300 can be connected to the oil inlet nozzle 233 through the grooves no matter how it rotates to any angle.

[0091] The above description describes that when the chain lubrication system is in operation, the two oil circuits supply oil to the two second chambers 220 , and the two oil circuits discharge oil from the second chambers 220 to the two oil outlet nozzles 230 through the two oil outlet channels 302 ;

[0092] Optionally, by synchronously changing the number of convex surfaces 411 and concave surfaces 412 on the cam 400, changing the number of oil outlets 3012 of the oil improvement channel 301, and changing the number of oil outlet channels 302, it is possible to realize three oil circuits supplying oil to the three second chambers 220, and three oil circuits discharging oil from the second chamber 220 to the three oil outlet nozzles 230 through the three oil outlet channels 302.

[0093] In one embodiment, the transmission assembly 110 includes: a worm gear 111 and a worm 112 assembled on the base 100;

[0094] The base 100 is provided with a first installation chamber 101 with an upward opening for accommodating the worm wheel 111 and a second installation chamber 102 with an opening toward the side for accommodating the worm 112; at least one end of the worm 112 extends out of the second installation chamber 102 for easy connection to an external power source, such as a motor.

[0095] The lower end of the main shaft 300 is inserted into the center of the worm gear 111 and fixed by a pin. The installation method is simple. After installation, when the worm gear 111 rotates, it drives the main shaft 300 to rotate in the first chamber 210.

[0096] Furthermore, a main body cover 250 is installed on the top of the main body 200, and the main body cover 250 covers the cam 400, the upper end of the main shaft 300 and the multiple piston rods 500 to play a protective role;

[0097] The main body cover 250 can be screwed onto the top of the main body 200 by means of threads, which is convenient for assembly.
