Description

Technical Field

[0001] The invention belongs to the field of lubrication, and in particular relates to a lubricating oil distributor module. Background Art

[0002] The petrochemical rubber industry mainly uses oil mist lubrication systems and manual refueling for lubrication. In recent years, oil and gas lubrication technology has gradually been used in the petrochemical rubber industry as an advanced lubrication method that is accurate, energy-saving, environmentally friendly, labor-saving and energy-saving. The equipment in the petrochemical industry mainly includes transmission systems, motors, water pumps, liquid pipeline pumps and circulation pumps, etc. The main lubrication parts include bearings, gear chains, hydraulic cylinders, piston rings, cylinders and valve stems, etc. The equipment in the rubber industry mainly includes rubber mixers, internal mixers, extruders, calenders and rubber cutting machines, etc. The main lubrication parts include front and rear rollers, transmission gears, reducers and transmission belt rollers, etc.

[0003] The lubricating parts in the petrochemical rubber industry are scattered, non-uniform in size and form. Special equipment is needed to deliver lubricating oil to each lubrication point and adjust the oil volume at each lubrication point to make the lubrication conditions adapt to the equipment requirements. On the other hand, the equipment in the petrochemical industry has a harsh operating environment and a complex friction pair structure. In actual work, it faces problems such as large impact loads, severe wear, large temperature changes, difficult lubrication, severe mechanical corrosion and rust, and environmental pollution. Therefore, such equipment also places higher requirements on the accuracy of the lubricating oil volume.

[0004] To solve the above problems, most oil-gas lubrication systems consisting of an oil supply station, a progressive distribution block, an oil-gas mixing block and an oil-gas distributor are currently used to provide oil-gas lubrication to multiple lubrication points. For example, in the integrated oil-gas distributor disclosed in the Chinese utility model patent with the authorization announcement number CN202580568U, the lubricating oil output from the oil supply station reaches the progressive distribution block and is divided into multiple channels of lubricating oil with different oil amounts, and then the multiple channels of lubricating oil enter the oil-gas mixing block for full mixing to obtain multiple channels of oil and gas, and then each channel of oil and gas is respectively delivered to the same lubrication point in equal amounts through an oil-gas distributor.

[0005] The application of this type of lubrication system in equipment in the petrochemical industry has significantly improved the use conditions of lubrication points such as bearings, increased the service life of bearings, reduced spare parts consumption and equipment operating costs, improved the on-site environment, and reduced pollution. However, there are also the following limitations:

[0006] 1. The oil-gas lubrication system consists of multiple equipment modules including an oil supply station, a progressive distribution block, an oil-gas mixing block and an oil-gas distributor. The system cost is relatively high, which increases the equipment operating cost.

[0007] Second, the existing lubrication method relies on compressed gas. In some occasions where there is no compressed gas, or when the gas supply is unexpectedly cut off, the oil and gas lubrication system cannot operate normally. Specifically, if there is no compressed gas, each lubricating oil entering the oil and gas mixing block cannot be output in a directional manner under the drive of compressed gas. Instead, it will be mixed through the compressed air main pipeline, causing the already distributed lubricating oil to be mixed again. At the same time, the oil and gas entering the oil and gas distributor will not be able to evenly adhere to the inner wall of the cavity with the distribution hole to settle and gather, and it is impossible to achieve equal distribution.

[0008] 3. The internal structure of the progressive distribution block is complex, and the internal oil channel is long and narrow. During the transportation process, the extrusion and kneading aggravate the separation of the base thin oil, resulting in saponification, deposition and hardening of the lubricating grease, so blockage often occurs. Since the progressive distribution block is oiled sequentially, once a blockage occurs, the entire lubrication system will be paralyzed. Summary of the invention

[0031] Compared with the prior art, the present invention has the following positive effects:

[0032] 1. The module of the present invention integrates oil quantity regulation, air flow regulation and oil quantity metering. One module can replace the progressive distribution block, the oil-gas mixing block and the oil-gas distributor to quantitatively supply oil to a lubrication point. Therefore, only multiple groups of the modules need to be configured on site, which occupies a small space and reduces the system cost.

[0033] 2. The present invention adopts modular design, which can be used alone or in parallel, and can meet the needs of different on-site installation distribution to the greatest extent. Moreover, when used in parallel, even if one path is blocked, it will not affect other lubricating oil paths, greatly improving the reliability of the system.

[0034] 3. The present invention utilizes the oil pressure of the lubricating oil to drive the first gear shaft to rotate, and the first gear shaft drives the second gear sleeve to rotate through meshing, thereby continuously sucking the lubricating oil from the oil inlet channel and pumping the lubricating oil into the oil outlet channel. The amount of oil delivered per rotation of the first gear shaft is proportional to the gear meshing length, so the amount of oil can be precisely controlled by adjusting the axial movement of the first gear shaft, and the accuracy of metering is also improved. At the same time, the oil cavity of this structure has no dead angle, small friction resistance, short and simple internal oil channels, and the continuous meshing and rubbing between the gear teeth also reduces the separation of the base thin oil, making it difficult for the lubricating grease to produce saponification, deposition and hardening, thus avoiding the occurrence of blockage.

[0035] 4. When there is no compressed gas, you only need to close the airflow regulating device, and normal lubrication can still be achieved by relying on the pressure of the lubricating oil, thus eliminating the dependence on compressed gas. It can be widely used in various occasions such as oil-gas lubrication and oil lubrication.

[0036] 5. The present invention ingeniously utilizes the cooperation between two sets of gear shafts and gear sleeves to achieve accurate volume adjustment. Moreover, since the corresponding gear shafts and gear sleeves are accurately matched, the sealing around the eccentric oil chamber is also guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0050] like Figure 1 and Figure 5 A micro adjustable lubricating oil metering distributor module for petrochemical rubber industry comprises a housing 1, wherein the housing 1 comprises an oil inlet channel, a working chamber, an oil outlet channel 4, an air inlet channel and an output channel 2.

[0051] The housing 1 is also provided with a gas input main channel 5 and a lubricating oil input main channel 15. The gas input main channel 5 is connected to the air inlet channel, and the lubricating oil input main channel 15 is connected to the oil inlet channel. Both ends of the gas input main channel 5 and both ends of the lubricating oil input main channel 15 are connected to the outer wall of the housing 1. When the housings 1 are installed side by side, the adjacent gas input main channels 5 and lubricating oil input main channels 15 are connected to each other as a whole, so as to realize the centralized transmission of compressed gas and lubricating oil.

[0052] The housing 1 is also provided with a transverse connection hole 20 for connecting side by side with the housing 1 of the adjacent micro adjustable lubricating oil metering distributor module for the petrochemical rubber industry, and a longitudinal mounting hole 21 for fixing the housing 1 on the mounting plate 22 below. When installing side by side, all the housings 1 can be connected as a whole through the transverse connection hole 20 and the long bolts, and then the row of housings 1 can be fixed on the mounting plate 22 below through the longitudinal mounting hole 21 and the long bolts.

[0053] Furthermore, if Figure 1 and Figure 3 The air intake passage is provided with an airflow regulating device. The airflow regulating device comprises an airflow regulating valve stem 3 installed on the housing 1 through a threaded connection, and a conical column 301 at the end of the airflow regulating valve stem 3 is inserted into the connection between the gas input main passage 5 and the air intake passage. The size of the opening of the connection can be adjusted by rotating the airflow regulating valve stem 3, and the position of the airflow regulating valve stem 3 can be locked by two locking nuts after adjustment.

[0054] Furthermore, if Figure 1 and Figure 4 The oil inlet channel includes a first oil inlet channel 16 and a second oil inlet channel 14 which are vertically connected. The oil inlet end of the first oil inlet channel 16 is connected to the lubricating oil input main channel 15.

[0055] An oil quantity regulating device is provided on the oil inlet passage. The oil quantity regulating device comprises an oil quantity regulating valve stem 17 installed on the housing 1 by threaded connection, and the circular column at the end of the oil quantity regulating valve stem 17 is inserted into the second oil inlet passage 14 and contacts and cooperates with the inner wall of the second oil inlet passage 14. A groove 1701 is provided on the circular column, and the outer end of the groove 1701 is located in the cavity where the first oil inlet passage 16 and the second oil inlet passage 14 are connected, and the inner end passes through the end of the circular column. Rotating the oil quantity regulating valve stem 17 can adjust the length of the groove 1701 in the cavity at the connection, so as to achieve the purpose of adjusting the amount and pressure of oil entering the second oil inlet passage 14.

[0056] like Figure 1 The oil inlet channel is connected to the oil outlet channel 4 through the working chamber.

[0057] like Figure 2 , Figure 6 and Figure 7, the working chamber is a horizontally arranged cylindrical chamber, in which a quantitative oil delivery mechanism is provided. The quantitative oil delivery mechanism comprises a rotatable first gear shaft 10 and a second gear sleeve 11, wherein the outer teeth of the first gear shaft 10 eccentrically mesh with the inner teeth of the second gear sleeve 11 to form an eccentric oil chamber 100. The gear teeth of the first gear shaft 10 are in an inward concave arc shape, and the inner teeth of the second gear sleeve 11 are in an outward convex arc shape. The number of inner teeth of the second gear sleeve 11 is one more than the number of outer teeth of the first gear shaft 10, so that one of the outer teeth of the first gear shaft 10 is close to one of the inner teeth of the second gear sleeve 11, and the approach point divides the eccentric oil chamber 100 into an oil inlet chamber and an oil outlet chamber.

[0058] The housing 1 also includes a volume adjustment mechanism for controlling the meshing length of the first gear shaft 10 and the second gear sleeve 11 so as to synchronously change the volumes of the oil inlet chamber and the oil outlet chamber.

[0059] Specifically, the volume adjustment mechanism includes a first gear sleeve 9, a spring 8, a second gear shaft 12 and an adjusting nut 18. The first gear sleeve 9 is coaxially arranged with the first gear shaft 10, and the left end of the first gear sleeve 9 is rotatably connected to the housing 1 through a bearing, and an oil seal is provided at the rotating connection. The toothed hole at the right end of the first gear sleeve 9 cooperates with the left end of the first gear shaft 10 to achieve a sliding connection, and the tooth profile at the cooperation is completely consistent, forming a boundary with good sealing performance at the left end of the eccentric oil chamber 100. The right end face of the first gear sleeve 9 is in sliding contact with the left end face of the second gear sleeve 11 to ensure that the two can rotate and move relative to each other. Since this place is immersed in lubricating oil during operation, the friction resistance is extremely small. The spring 8 is installed in the toothed hole of the first gear sleeve 9 to push the first gear shaft 10 to the right.

[0060] The second gear shaft 12 is coaxially arranged with the second gear sleeve 11. The left end of the second gear shaft 12 cooperates with the right end of the toothed hole of the second gear sleeve 11 to achieve a sliding connection. The toothed shapes at the cooperation are completely consistent, forming a well-sealed boundary at the right end of the eccentric oil chamber 100. The left end face of the second gear shaft 12 is in sliding contact with the right end face of the first gear shaft 10 to ensure that the two can rotate and move relative to each other. Since this part is immersed in lubricating oil during operation, the friction resistance is extremely small. The first gear shaft 10 is always in contact with the second gear shaft 12 under the action of the spring 8.

[0061] Furthermore, the first gear shaft 10 is provided with a first vent hole 1001 extending from the left end to the right end, and the second gear shaft 12 is provided with a second vent hole 1201 extending from the left end to the outer circumferential surface, and the right end of the first vent hole 1001 is connected to the left end of the second vent hole 1201. The first vent hole 1001 and the second vent hole 1201 can connect the inner cavity of the first gear sleeve 9 with the outside, so as to prevent the first gear shaft 10 from being subjected to resistance generated by gas when moving in the inner cavity of the first gear sleeve 9.

[0062] The adjusting nut 18 is connected to the threaded hole on the positioning sleeve 13, and the axis of the threaded hole coincides with the axis of the second gear shaft 12. The right end of the second gear shaft 12 is rotatably connected to the adjusting nut 18 through a bearing, and an oil seal is provided at the rotatable connection. Figure 8 , Fig. 9 , Fig.10 By rotating the adjusting nut 18, the axial position of the second gear shaft 12 can be changed, and the axial position of the first gear shaft 10 also changes accordingly, thereby achieving the purpose of adjusting the axial length of the eccentric oil chamber 100. Fig.10 When the second gear shaft 12 moves leftward until the step surface at the upper end of the second vent hole 1201 contacts the end surface of the second gear sleeve 11, the volume of the eccentric oil chamber 100 is minimum.

[0063] Furthermore, a locking screw ring 23 located on the right side of the adjusting nut 18 and a limiting snap ring 19 located on the right side of the locking screw ring 23 are also installed in the threaded hole on the positioning sleeve 13. The locking screw ring 23 can lock the position of the adjusting nut 18, and the limiting snap ring 19 is used to limit the extreme position of the adjusting nut 18 moving outward to prevent the second gear shaft 12 from being out of contact with the first gear shaft 10.

[0064] Furthermore, if Figure 2 , Figure 6 and Figure 7 A positioning sleeve 13 is installed in the working chamber, and the outer circumferential surface of the second gear sleeve 11 cooperates with the inner hole of the positioning sleeve 13 to realize the rotation connection between the second gear sleeve 11 and the positioning sleeve 13. A first oil hole 1301 is provided on the outer wall of the positioning sleeve 13 near the end of the second oil inlet channel 14, and a second oil hole 1302 is provided on the side near the oil outlet channel 4.

[0065] The second gear sleeve 11 is evenly distributed on the circumference with a plurality of oil grooves 1101 that pass through from the inner wall to the outer wall, and the length direction of the oil grooves 1101 is consistent with the axial direction of the second gear sleeve 11. No matter to which angle the second gear sleeve 11 rotates, the lubricating oil in the second oil inlet channel 14 can enter the oil inlet chamber through the first oil hole 1301 and the oil groove 1101 on the corresponding side in sequence. The pressure of the lubricating oil causes the first gear shaft 10 to rotate, and the second gear sleeve 11 rotates accordingly, and the two bring the oil in the oil inlet chamber to the oil outlet chamber during the eccentric meshing rotation. At the same time, the pressure of the lubricating oil will be transmitted from the oil inlet chamber to the side of the oil outlet chamber through the gears, so the oil squeezed out of the oil outlet chamber is also pressurized. The lubricating oil in the oil outlet chamber eventually reaches the oil outlet channel 4 through the oil groove 1101 on the corresponding side and the second oil hole 1302.

[0066] Furthermore, if Figure 1The end of the air inlet channel and the end of the oil outlet channel 4 intersect at the starting end of the output channel 2. After the compressed gas in the air inlet channel is fully mixed with the lubricating oil in the oil outlet channel 4, it passes through the output channel 2 and the connected pipeline to reach the lubrication point.

[0067] like Figure 1 The micro adjustable lubricating oil metering distributor module for the petrochemical rubber industry further includes a sensing part 7 that rotates with the first gear shaft 10. The housing 1 is also provided with a sensor 6 for detecting the sensing part 7. In this embodiment, the sensing part 7 is arranged on the first gear shaft 10 and is eccentrically arranged relative to the axis of the first gear shaft 10. The number of rotations obtained by the sensor 6 can achieve metering, and the oil supply cycle can also be controlled based on the number of feedbacks.

[0068] During operation, multiple modules are fixed side by side to the mounting plate 22, and then the output oil pressure of the oil supply station is adjusted to ensure that the pressure can drive all quantitative oil delivery mechanisms to work normally. Then, according to the needs of each lubrication point, each oil quantity regulating valve stem 17 is adjusted, and the speed of the gear in each quantitative oil delivery mechanism also changes accordingly. The current speed can be detected by the sensor 6. Since the amount of oil output per unit time of the quantitative oil delivery mechanism is proportional to the product of the gear speed and the volume of the eccentric oil chamber 100, and the calculation relationship can be determined by measurement and other methods, the corresponding relationship between the position of the adjusting nut 18 and the volume size can be fully determined in advance. After adjusting the speed, the volume size can be further fine-tuned by adjusting the nut 18 so that the oil volume meets the lubrication requirements.

[0069] When there is no compressed gas on site, the airflow regulating valve stem 3 can also be closed to achieve oil lubrication. At this time, the amount of lubricating oil in each channel is still independent and accurately controllable.

[0070] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
