Description

Technical Field

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

[0002] At present, in the lubrication systems used in large machinery, especially progressive lubrication systems, plunger distributors are usually used to distribute lubricants to one or more lubrication points in a metered manner. These distributors are usually implemented in a purely mechanical structure, and a fixed amount of lubricant is distributed as each plunger stroke is metered. Depending on the applied pressure, the plunger is controlled to move in one direction or another, and the amount of lubricant distributed can be determined by measuring the number or time of the plunger movement stroke.

[0003] In order to operate correctly, that is, to determine whether the plunger has correctly executed the expected stroke, the current common distributors use stroke sensors to monitor the movement of the plunger. In addition, in order to squeeze the grease to the lubrication points at different distances, there is a high pressure of several hundred bars inside the distributor, so the sleeve and plunger are closed structures. This design has very high requirements for the airtightness of the components, and because the reciprocating motion of the plunger will inevitably cause wear, after a certain period of use, it will affect the performance of the components and cause inaccurate lubricant distribution. At the same time, because the wear gap of the components will cause lubricant deposition, the lubricant will condense into blocks over time, causing blockage of the plunger movement structure.

[0004] Therefore, in order to solve the above problems, a lubricating oil distributor is needed, which has a simple structure, is easy to manufacture, has low cost and high reliability. Summary of the invention

[0005] In view of this, an object of the present invention is to overcome the defects in the prior art and provide a lubricating oil distributor with a simple structure, easy production and manufacturing, low cost and high reliability.

[0006] The lubricating oil distributor of the present invention comprises at least a distributor for distributing lubricating oil to different lubrication points, a power source for driving the distributor, and a controller for controlling the power source, wherein the distributor comprises at least:

[0007] The rotating disk is used to set a lubricating oil flow channel I for the circulation of lubricating oil, and can be driven by a power source to rotate around the axis of the rotating disk;

[0008] The distributor seat is used to install the rotating disk, and the distributor seat is evenly arranged with multiple lubricating oil flow channels II around the axis of the rotating disk, and the power source can be controlled by the controller to drive the rotating disk to rotate, so that the lubricating oil flow channel I is connected with multiple lubricating oil flow channels II in sequence.

[0009] Furthermore, the distributor also includes a fixed disk, which is coaxially arranged with the rotating disk and fixed to the distributor seat, and the multiple lubricating oil flow channels II are opened on the fixed disk.

[0010] Furthermore, it also includes a pressure sensor, which is fixedly installed in one of the lubricating oil flow channels II and blocks it.

[0011] Furthermore, the lubricating oil flow channel I includes an inlet I for the lubricating oil to flow in, an outlet I for the lubricating oil to flow out and connected to the lubricating oil flow channel II, and a connecting flow channel I connecting the inlet I and the outlet I, and the distance from the inlet I to the axis of the rotating disk is smaller than the distance from the outlet I to the axis of the rotating disk.

[0012] Furthermore, the inlet I, outlet I and connecting flow channel I are located in the same plane.

[0013] Furthermore, it also includes an overflow valve, which is arranged on the rotating disk and connected to the connecting flow channel I.

[0014] Furthermore, the rotating disk is in a cone shape, and the inlet I is opened at the small end of the rotating disk in the cone shape.

[0015] Furthermore, the power source is a stepping motor.

[0016] Furthermore, there are eight lubricating oil flow channels II.

[0017] Furthermore, it also includes a support seat, which is arranged along the axis of the rotating disk and away from the fixed disk and fixed to the distributor seat. The two ends of the rotating disk can rotate around the axis of the rotating disk and are respectively arranged on the support seat and the fixed disk.

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0020] Figure 1 It is a structural schematic diagram of the present invention;

[0021] Figure 2 It is a structural diagram of the fixed disk of the present invention. DETAILED DESCRIPTION

[0022] Figure 1 It is a structural schematic diagram of the present invention, Figure 2 It is a structural diagram of the fixed disk of the present invention; as shown in the figure, the lubricating oil distributor in this embodiment at least includes a distributor for distributing lubricating oil to different lubrication points, a power source 6 for driving the distributor and a controller for controlling the power source, and the distributor at least includes: a rotating disk 4, which is used to set a lubricating oil flow channel Ⅰ41 for the circulation of lubricating oil, and can be driven by the power source 6 to rotate around the axis of the rotating disk; a distributor seat 9, which is used to install the rotating disk 4, and the distributor seat 9 is evenly provided with multiple lubricating oil flow channels Ⅱ5a around the axis of the rotating disk, and the power source 6 can be controlled by the controller to drive the rotating disk 4 to rotate, so that the lubricating oil flow channel Ⅰ41 is connected with multiple lubricating oil flow channels Ⅱ5a in sequence. The lubricating oil distributor adopting this structure can not only distribute the lubricating oil to the lubrication points that need lubrication at various places, but also has a simple structure, which is convenient for the processing, manufacturing, production and assembly of the distributor, thereby improving production efficiency, reducing production costs, and reducing wear between parts, thereby improving the service life of the distributor and the accuracy of lubricating oil distribution, avoiding waste caused by excessive lubricating oil or insufficient lubrication caused by too little lubricating oil; the controller controls the power source 6 to drive the rotating disk 4 to rotate, and when the lubricating oil flow channel I41 is connected to one of the lubricating oil flow channels II5a, the controller controls the power source 6 to stop rotating, so that the lubricating oil is pumped from the oil tank 1 through the oil delivery hose 2 through the lubricating oil flow channel I41 and the corresponding lubricating points of the lubricating oil flow channel II5a for lubrication (the flow direction of the lubricating oil is shown in the attached manual). Figure 1 In the direction of the middle arrow), after the amount of lubricating oil flowing to the lubrication point is sufficient, the controller controls the power source to drive the rotating disk to rotate, so that when the lubricating oil flow channel I41 is connected to the next lubricating oil flow channel II5a, the controller controls the power source 6 to stop, and the lubricating oil flows through the lubricating oil flow channel I41 and the next lubricating oil flow channel II5a to the lubricating point corresponding to the next lubricating oil flow channel II for lubrication. After the lubricating oil flows to the lubricating point corresponding to the lubricating oil flow channel II in sufficient amount (determined by the pressure of the lubricating oil and the set time), the controller controls the power source to drive the rotating disk to rotate and enter the next lubricating oil flow channel II, and circulate in sequence, which will not be repeated here. The lubricating oil flow channel I41 and the lubricating oil flow channel II5a are provided with position sensors, so that when the lubricating oil flow channel I41 and the lubricating oil flow channel II5a are connected, the position sensor transmits a control signal to the controller, so that the controller controls the driving source 6 to stop, and after the set time, the power source 6 is started again to drive the rotating disk 4 to rotate. The circuit structure of the controller driving / stopping the power source by receiving the signal is the prior art, which will not be repeated here.

[0023] The lubricating oil flow channel I 41 can be opened in the rotating disk 4, or can be separately set outside the rotating disk, which will not be described in detail here. The power source 6 can directly drive the rotating disk to rotate, or an intermediate transmission mechanism can be set to drive the rotating disk to rotate, which will not be described in detail here. The multiple lubricating oil flow channels II can be directly opened in the distributor seat, or can be set in the intermediate component of the distributor seat, which can be selected according to specific needs, which will not be described in detail here. The distributor seat 9 is used to install the distributor and the power source, and its specific structure is a well-known technology for those skilled in the art, which will not be described in detail here.

[0024] In this embodiment, the distributor also includes a fixed disk 5, which is coaxially arranged with the rotating disk 4 and fixed to the distributor seat 9, and the multiple lubricating oil flow channels II5a are opened on the fixed disk 5; adopting this structure, it is convenient to process and manufacture the lubricating oil flow channels II5a, thereby improving the manufacturing accuracy, facilitating the connection with the lubricating oil flow channels I41, so that the lubricating oil flows smoothly, and also reduces the production cost, and also has the advantage of preventing lubricating oil blockage.

[0025] In this embodiment, a pressure sensor 7 is also included. The pressure sensor 7 is fixedly installed on one of the lubricating oil flow channels II5a and seals it. By setting the pressure sensor 7, when the rotating disk 4 is rotated to this position, the pressure sensor transmits the detected pressure value to the controller. When the pressure of the lubricating oil is insufficient, the controller controls the lubricating oil pump to pressurize the lubricating oil to meet the pressure requirement, thereby calibrating the pressure so that the flow rate of the lubricating oil (the flow rate is determined by pressure and time) remains stable. The lubricating oil is pressurized by the lubricating oil pump and controlled by the controller, which is a prior art and will not be repeated here. The pressure sensor 7 and one of the lubricating oil flow channels II5a are sealed by a threaded seal.

[0026] In this embodiment, the lubricating oil flow channel I41 includes an inlet I41a for the lubricating oil to flow in, an outlet I41c for the lubricating oil to flow out and connected to the lubricating oil flow channel II, and a connecting flow channel I41b connecting the inlet I41a and the outlet I41c. The distance from the inlet I41a to the axis of the rotating disk is smaller than the distance from the outlet I41c to the axis of the rotating disk. By adopting the lubricating flow channel I41 of this structure, not only the circulation of the lubricating oil is facilitated, but also the compactness of the structure is improved. By making the distance from the inlet I41a to the axis of the rotating disk smaller than the distance from the outlet I41c to the axis of the rotating disk, the lubricating oil flow channel I41 can be easily adjusted. 1c to the axis of the rotating disk, which can not only reduce the rotational inertia of the rotating disk and increase the reliability of the rotation of the rotating disk 4, but also has the advantage of facilitating the arrangement of the outlet Ⅰ41c. The outlet 41c is arranged at one end of the fixed disk along the axis of the rotating disk, and the inlet 41a is arranged away from one end of the fixed disk along the axis of the rotating disk. The distance from the inlet Ⅰ41a to the axis of the rotating disk is smaller than the distance from the outlet Ⅰ41c to the axis of the rotating disk, which means that the distance from the axis of the inlet 41a to the axis of the rotating disk is smaller than the distance from the axis of the outlet Ⅰ41c to the axis of the rotating disk.

[0027] In this embodiment, the inlet I41a, outlet I41c and connecting flow channel I41b are located in the same plane; by adopting this structural setting, it is not only easy to process and manufacture, but also can reduce the circulation time of the lubricating oil, and avoid the waste of lubricating oil due to the long circulation path of the lubricating oil; the meaning of being located in the same plane is that the central axes of the inlet I, outlet I and connecting flow channel I are located in the same plane. Of course, the connecting flow channel 41b can also be set to a spiral shape, which will not be repeated here.

[0028] In this embodiment, an overflow valve 8 is also included, and the overflow valve 8 is arranged on the rotating disk 4 and connected to the connecting flow channel I 41; by setting the overflow valve 8, when the lubricating oil pressure in the connecting flow channel I 41 is too high, it can be discharged through the overflow valve, thereby improving the reliability and safety of the distributor; the side of the rotating disk 4 is also provided with an overflow flow channel 42 connected to the connecting flow channel 41b, and the overflow valve 8 is installed in the overflow flow channel 42, so that when the pressure in the lubricating oil flow channel I 41 is too high, the pressure is released through the overflow valve to avoid damage to the rotating disk due to excessive pressure.

[0029] In this embodiment, the rotating disk 4 is conical in shape, and the inlet Ⅰ41a is opened at the small end of the conical rotating disk; by adopting this structural arrangement, the compactness of the structure is increased, the structure of the rotating disk is reduced, and the production cost is reduced; the rotating disk is conical in shape, and the small end of the cone is arranged on the side of the oil delivery hose 2, so that the inlet Ⅰ41a is arranged at the small end of the rotating disk, and the inlet 41a is arranged coaxially with the axis of the rotating disk, and the outlet 41c is arranged at the large end of the rotating disk.

[0030] In this embodiment, the power source 6 is a stepper motor 6; by adopting a stepper motor, it has the advantages of high control accuracy, light weight, and high reliability; the stepper motor is also equipped with a brake, so that the stepper motor is braked after the stepper motor stops, thereby braking the rotating disk 4, avoiding the rotating disk from rotating due to the flow of lubricating oil, thereby improving the reliability of the dispenser.

[0031] In this embodiment, there are eight lubricating oil flow channels II5a; eight lubricating oil flow channels II are used here to meet the lubrication requirements of the lubrication points. Of course, other numbers can be selected according to the number of required lubrication points, which will not be repeated here; one of the eight lubricating oil flow channels II5a is blocked and installed with a pressure sensor 7.

[0032] In the present embodiment, it also includes a support seat 3, which is arranged on the side away from the fixed plate 5 along the axis of the rotating disk and fixed to the distributor seat 9, and the two ends of the rotating disk 4 can rotate around the axis of the rotating disk and are respectively arranged on the support seat 3 and the fixed plate 4; by setting the support seat 3, the structure of the distributor seat 9 is simplified, which is convenient for production and manufacturing, and at the same time, the rotating disk 4 can rotate smoothly. The two ends of the rotating disk can rotate around the axis of the rotating disk and are respectively arranged on the support seat and the fixed plate. The meaning is that the two ends of the rotating disk 4 are respectively rotatably connected with the support seat 3 and the fixed plate 5, and rotate around the axis of the rotating disk. The rotating disk is a circular rotating disk, and the support seat 3 is provided with a support shaft Ⅰ31 for rotatably connecting with the rotating disk 4. The rotating disk 4 is provided with a countersunk hole Ⅰ for rotatably cooperating with the support shaft Ⅰ31 on the side of the support seat, and the fixed plate 5 is provided with a support shaft Ⅱ51 rotatably connected with the rotating disk on the side of the rotating disk. The rotating disk is provided with a countersunk hole II for cooperating with the support shaft II on the side close to the fixed disk, and the support shaft I31 and the support shaft II51 are coaxially arranged with the axis of the rotating disk, so that the countersunk hole I of the rotating disk cooperates with the support shaft I, and the countersunk hole II of the rotating disk cooperates with the support shaft II, so that the rotating disk can be driven by the power source to rotate around the support shaft I and the support shaft II; the support seat is provided with a connecting through hole 32 for connecting with the inlet I along the axis direction of the rotating disk, and the connecting through hole 32 is coaxially arranged with the axis of the rotating disk, which can increase the compactness of the structure and reduce the influence on the rotation of the rotating disk 4. The inlet I is coaxially arranged with the axis of the rotating disk, which is convenient for connecting with the connecting through hole 32 and can increase the reliability of the rotation of the rotating disk. By connecting the oil delivery hose to one end of the connecting through hole 32 (away from the end of the inlet I), when the rotating disk rotates, it will not affect the oil delivery hose to deliver the lubricating oil to the inlet I41a through the connecting through hole 32.
