Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a hydraulic motor. Background Art

[0002] The hydraulic motor is an actuator of the hydraulic system. It converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft. The liquid is the medium for transmitting force and motion. It is mainly used in machinery, ships, hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, marine machinery, petrochemical industry, port machinery, etc.

[0003] The existing patent (Announcement No.: CN112343767A) proposes an ultra-micro-axis distribution type cycloid hydraulic motor, whose structure includes a body, a fixed plate, a shaft rod, and a hydraulic port. The right side of the fixed plate is connected to the left end of the body by welding, the shaft rod runs through the axis of the body, and the hydraulic port is embedded in the outer surface of the body. The body includes a fixed block, a hydraulic box, a refueling port, a lubrication cylinder, and a positioning block. One end of the fixed block is embedded in the inner wall of the body, the hydraulic box is welded to the other end of the fixed block and is connected to the hydraulic port, the refueling port is embedded in the upper right surface of the body, the left end of the lubrication cylinder is connected to the right surface of the hydraulic box by welding, the positioning block horizontally runs through the inside of the hydraulic box and is connected to the shaft rod, the refueling port opens upward, and the lubrication cylinder is a horizontally placed funnel shape.

[0004] At present, there is an ultra-micro-axis distribution type cycloidal hydraulic motor. In order to make the cycloidal hydraulic motor run smoothly, it is necessary to regularly add lubricating oil to the cycloidal hydraulic motor. When adding lubricating oil, it is necessary to open the refueling port of the cycloidal hydraulic motor and connect it to the refueling pipe to add lubricating oil to the cycloidal hydraulic motor. When the lubricating oil is added to a sufficient amount, the lubricating oil remaining in the refueling pipe still flows to the refueling port, causing excessive overflow of lubricating oil in the cycloidal hydraulic motor and adhering to the surface of the cycloidal hydraulic motor, causing pollution to the cycloidal hydraulic motor. The present invention mainly solves the problem of pollution caused by lubricating oil adhesion.

[0005] However, since this equipment manually adds lubricating oil, it is often necessary to prepare a sufficient amount of lubricating oil to achieve the lubrication effect, which is very easy to cause waste. In the later stage, a large amount of contaminated lubricating oil is deposited at the bottom of the motor. If it is not cleaned in time, it will cause damage to the operation of the motor.

[0006] For this purpose, we propose a hydraulic motor. Summary of the invention

[0007] The object of the present invention is to provide a hydraulic motor. When the circuit is turned on, the electromagnetic base plate is energized synchronously to generate magnetism. Before the power is turned on, the electromagnetic base plate is an ordinary plate without magnetism. As the electromagnetic base plate is energized, magnetism is generated, and then relative adsorption is generated on the magnet. The magnet is immediately attracted and rotates around the rotation axis as the base point. The magnet then deflects and loosens the contact with the motor main body shell, making it convenient for the staff to remove the rear shell and clean the accumulated lubricating oil, thereby avoiding long-term accumulation of lubricating oil to cause damage to the motor body, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A hydraulic motor comprises a motor body and a mounting shell, wherein an output shaft is movably mounted inside the mounting shell, the output shaft is cylindrical as a whole, and a protrusion is provided on its cylindrical outer surface, a mounting base is provided below the mounting shell, a protective curved plate is fixedly connected to the top of the mounting base, an oil filling port is provided at the top of the motor body, and a motor coil is provided inside the motor body.

[0010] An oil separation mechanism is arranged below the oil filling port, and an oil separation block is arranged below the oil filling port. The oil separation block is cylindrical as a whole, and its top end is arranged in a hemispherical shape. An oil lowering channel is arranged on the outside of the oil separation block, and a mounting seat is movably connected below the oil separation block. Oil containing channels are arranged on both sides of the bottom end of the oil separation block, and the oil separation mechanism is formed among the oil separation block, the oil lowering channel, the mounting seat and the oil containing channel.

[0011] A vibration mechanism and a drainage mechanism are arranged below the oil separation mechanism.

[0012] The staff will add the lubricating oil into the interior of the motor body from the oil filling port in advance. The lubricating oil enters from the oil filling port and first falls to the top of the oil separator block. The top of the oil separator block is hemispherical, and the lubricating oil that falls on it is separated and flows to the oil lowering channels on both sides, which cushions the fall of the lubricating oil and ensures that the lubricating oil falls in order, so that the tension of the lubricating oil is fully stretched.

[0013] Preferably, a rotating disc is provided below the mounting seat, and a mounting axis is provided on the outer surface of the rotating disc. The mounting axis is eccentrically mounted on the rotating disc, and a shaft is connected to the outer side of the mounting axis. A knocking plate is connected to the end of the shaft away from the mounting axis. The knocking plate is rectangular, and the knocking plate and the shaft are movably connected. A universal shaft is inserted at the connection. An outer wall is fitted on the outer side of the knocking plate, and an oil outlet extends from the bottom end of the outer wall. A vibration mechanism is formed among the mounting seat, the rotating disc, the mounting axis, the shaft, the knocking plate, the outer wall and the oil outlet.

[0014] The lubricating oil continues to fall from the oil lower channel and passes through the oil containing channel. At this time, the built-in driving element of the rotating disc starts to work, driving the rotating disc to start rotating. The rotating disc then drives the installation axis to make circular reciprocating motion. The installation axis then drives the shaft to start moving. The shaft then drives the knocking plate connected to it to make reciprocating motion. The knocking plate then reciprocates synchronously to knock on the outer wall. As the outer wall is knocked, vibration is generated, which increases the flow rate of the lubricating oil. At the same time, it also prevents the lubricating oil from adhering to the outer wall and causing subsequent secondary pollution.

[0015] Preferably, a drainage disc is provided below the oil outlet, a driving axis is provided inside the drainage disc, two groups of rod bodies are connected to the outer side of the driving axis, and the plane heights of the two groups of rod bodies are higher than the drainage disc, a drainage groove is formed between the two groups of rod bodies, and a drainage mechanism is formed between the oil outlet, the drainage disc, the driving axis and the drainage groove.

[0016] The lubricating oil finally passes through the oil outlet and reaches the drainage mechanism below it. The driving axis inside the drainage mechanism rotates synchronously, driving the drainage groove to rotate in a circular shape synchronously. The drainage groove then receives the lubricating oil flowing from the oil outlet, drives it, and reasonably distributes the lubricating oil to both sides.

[0017] Preferably, oil outlet channels are provided on both sides of the left and right sides of the drainage disc, a Tesla valve is provided inside the oil outlet channel, one end of the oil outlet channel is connected to the drainage disc, and the other end is connected to the oil storage bag, the outside of the oil storage bag is connected to the oil injection pipe, and the end of the oil injection pipe away from the oil storage bag is connected to the nozzle, and the nozzle is truncated cone-shaped.

[0018] When the drainage groove is connected to the oil outlet channel, the lubricating oil in the drainage groove immediately enters the oil outlet channel, and enters the oil storage bag from the Tesla valve inside the oil outlet channel. The oil storage bag stores the lubricating oil. When the lubricating oil in the oil storage bag is full, as the Tesla valve continues to deliver oil, more and more lubricating oil is stored in the oil storage bag. Since the Tesla valve is a one-way valve, the Tesla valve on it is a one-way flow valve invented by the famous American scientist Nikola Tesla. It has no moving parts and can achieve one-way flow without inputting energy. It is a one-way gas flow valve, which is also suitable for one-way liquid. Circulation, since one end of the oil storage bag is connected to the Tesla valve, the overflowing lubricating oil cannot flow out from the end of the Tesla valve, and a pressure valve is arranged in the nozzle 25. When the pressure reaches a certain value, the overflowing lubricating oil in the oil storage bag 23 finally passes through the oil injection pipe 24 and is sprayed from the nozzle 25, and is sprayed to the motor coil 7 and one end of the output shaft 3, thereby realizing the lubrication of the inside of the motor body 1 and realizing precise lubrication. Moreover, the volume of the oil storage bag 23 is relatively small, and only a small amount of oil needs to be injected through the oil filling port 6, so that it can be sprayed out at a fixed point from the nozzle 25, realizing precise lubrication and avoiding a large amount of waste caused by adding lubricating oil by traditional means.

[0019] Preferably, an electromagnetic base plate is provided at the bottom of the inner cavity of the motor body, a mounting plate is provided below the electromagnetic base plate, three groups of mounting plates are provided and are connected laterally, reset springs are connected below the mounting plates at both sides, a trigger switch head is connected below the mounting plate at the middle position, a trigger switch wire is connected to the outside of the trigger switch head, and a buzzer is provided inside the motor body and below the electromagnetic base plate.

[0020] After the lubricating oil lubricates the motor coil, the excess lubricating oil will inevitably fall and accumulate at the bottom of the inner cavity of the motor body, namely the electromagnetic base plate. As the lubricating oil continues to accumulate on the electromagnetic base plate, the weight of the electromagnetic base plate increases accordingly, and the electromagnetic base plate drives the mounting plate connected to its inner side to drop accordingly. The mounting plate then drives the reset spring and the trigger switch head to drop synchronously, and the trigger switch head then presses the trigger switch wire inward, and the two sets of relative trigger switch wires immediately come into contact with each other, and the internal circuit is immediately turned on, and the buzzer then starts to alarm, emitting a sharp alarm sound to alert the staff.

[0021] Preferably, a magnet is provided below the outer shell of the motor body, the magnet is vertically mounted and fits the outer shell of the motor body, a rotating shaft is movably connected below the magnet, and a fixed bracket is provided at the vertical connection between the rotating shaft and the magnet.

[0022] When the circuit is turned on, the electromagnetic base plate is energized to generate magnetism. Before power is turned on, the electromagnetic base plate is an ordinary plate without magnetism. As the electromagnetic base plate is energized, magnetism is generated, which in turn causes relative adsorption to the magnet. The magnet is immediately attracted and rotates around the axis of rotation. The magnet then deflects, loosening the contact with the motor body shell, making it convenient for the staff to remove the rear shell and clean the accumulated lubricating oil, thereby preventing the long-term accumulation of lubricating oil from causing damage to the motor body.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The hydraulic motor has a hemispherical top end, and the lubricating oil falling on the top end is separated and flows to the lower oil channels on both sides, so as to buffer the fall of the lubricating oil, ensure the orderly fall of the lubricating oil, and fully stretch the tension of the lubricating oil.

[0025] 2. The hydraulic motor drives the knocking plate connected to it to do reciprocating motion through the shaft rod, and the knocking plate then synchronously reciprocates to knock the outer wall. As the knocking on the outer wall occurs, vibration is generated, which increases the flow rate of the lubricating oil. At the same time, it also prevents the lubricating oil from adhering to the outer wall and causing subsequent secondary pollution.

[0026] 3. For this hydraulic motor, since one end of the oil storage bag is connected to the Tesla valve, the overflowing lubricating oil cannot flow out from the Tesla valve. The overflowing lubricating oil in the oil storage bag can only be sprayed out from the nozzle through the injection pipe and sprayed onto the motor coil and one end of the output shaft, thereby achieving lubrication inside the motor body, realizing precise lubrication, and avoiding a lot of waste caused by traditional means of adding lubricating oil.

[0027] 4. The hydraulic motor is connected through the circuit, and the electromagnetic base plate is energized synchronously to generate magnetism. Before power is turned on, the electromagnetic base plate is an ordinary plate without magnetism. As the electromagnetic base plate is energized, it generates magnetism, which in turn produces relative adsorption to the magnet. The magnet is immediately attracted and rotates around the rotation axis as the base point. The magnet then deflects and loosens the contact with the motor body shell, making it convenient for the staff to remove the rear shell and clean the accumulated lubricating oil to avoid damage to the motor body caused by long-term accumulation of lubricating oil.

[0042] See also Figures 1 to 10The present invention provides a hydraulic motor, and the technical solution is as follows:

[0044] An oil separation mechanism is arranged below the oil filling port 6. An oil separation block 8 is arranged below the oil filling port 6. The oil separation block 8 is cylindrical in shape as a whole, and its top end is arranged in a hemispherical shape. An oil lowering channel 9 is arranged on the outer side of the oil separation block 8. A mounting seat 10 is movably connected below the oil separation block 8. Oil containing channels 11 are arranged on both sides of the bottom end of the oil separation block 8. The oil separation mechanism is formed between the oil separation block 8, the oil lowering channel 9, the mounting seat 10 and the oil containing channel 11.

[0045] A vibration mechanism and a drainage mechanism are arranged below the oil separation mechanism.

[0046] The staff adds the lubricating oil into the interior of the motor body 1 from the oil filling port 6 in advance. The lubricating oil enters from the oil filling port 6 and first falls to the top of the oil dividing block 8. The top of the oil dividing block 8 is hemispherical, and the lubricating oil falling on it is separated and flows to the lower oil channels 9 on both sides, which cushion the fall of the lubricating oil, ensure the orderly fall of the lubricating oil, and fully stretch the tension of the lubricating oil.

[0047] As an embodiment of the present invention, refer to Figure 3-5 A rotating disc 12 is arranged below the mounting seat 10, and a mounting axis 13 is arranged on the outer surface of the rotating disc 12. The mounting axis 13 is eccentrically mounted on the rotating disc 12, and a shaft 14 is connected to the outer side of the mounting axis 13. A knocking plate 15 is connected to the end of the shaft 14 away from the mounting axis 13. The knocking plate 15 is rectangular, and the knocking plate 15 and the shaft 14 are movably connected. A universal shaft is inserted at the connection. An outer wall 16 is fitted on the outer side of the knocking plate 15, and an oil outlet 17 extends from the bottom end of the outer wall 16. A vibration mechanism is formed between the mounting seat 10, the rotating disc 12, the mounting axis 13, the shaft 14, the knocking plate 15, the outer wall 16 and the oil outlet 17.

[0048] The lubricating oil continues to fall from the oil lower channel 9 and passes through the oil containing channel 11. At this time, the built-in driving element of the rotating disc 12 starts to work, driving the rotating disc 12 to start rotating, and the rotating disc 12 then drives the mounting axis 13 to make a circular reciprocating motion, and the mounting axis 13 then drives the shaft 14 to start moving, and the shaft 14 then drives the knocking plate 15 connected thereto to make a reciprocating motion, and the knocking plate 15 then synchronously reciprocates to knock the outer wall 16, and vibration is generated as the outer wall 16 is knocked, thereby increasing the flow speed of the lubricating oil. At the same time, it also prevents the lubricating oil from adhering to the outer wall 16 and causing subsequent secondary pollution.

[0049] As an embodiment of the present invention, refer to Figure 7 A drainage disc 18 is provided below the oil outlet 17, a driving shaft 19 is provided inside the drainage disc 18, two groups of rod bodies are connected to the outer side of the driving shaft 19, and the plane heights of the two groups of rod bodies are higher than the drainage disc 18, a drainage groove 20 is formed between the two groups of rod bodies, and a drainage mechanism is formed between the oil outlet 17, the drainage disc 18, the driving shaft 19 and the drainage groove 20.

[0050] The lubricating oil finally passes through the oil outlet 17 and reaches the drainage mechanism below it. The driving shaft 19 inside the drainage mechanism rotates synchronously, driving the drainage groove 20 to rotate synchronously in a circle. The drainage groove 20 then receives the lubricating oil flowing down from the oil outlet 17, drives it, and reasonably distributes the lubricating oil to both sides.

[0051] As an embodiment of the present invention, refer to Figure 6-8 An oil outlet channel 21 is provided on both sides of the drainage disc 18, and a Tesla valve 22 is provided inside the oil outlet channel 21. One end of the oil outlet channel 21 is connected to the drainage disc 18, and the other end is connected to an oil storage bag 23. The outer side of the oil storage bag 23 is connected to an oil injection pipe 24, and the end of the oil injection pipe 24 away from the oil storage bag 23 is connected to a nozzle 25, and the nozzle 25 is in a truncated cone shape.

[0052] When the drainage groove 20 is connected to the oil outlet channel 21, the lubricating oil received in the drainage groove 20 immediately enters the oil outlet channel 21, and enters the oil storage bag 23 from the Tesla valve 22 inside the oil outlet channel 21. The oil storage bag 23 stores the lubricating oil. When the lubricating oil in the oil storage bag 23 is full, as the Tesla valve 22 continues to deliver oil, more and more lubricating oil is stored in the oil storage bag 23. Since the Tesla valve 22 is a one-way valve, the Tesla valve 22 thereon is a one-way flow valve invented by the famous American scientist Nikola Tesla. It has no moving parts and can achieve one-way flow of airflow without inputting energy. It is a one-way gas circulation valve, also The same is true for the one-way flow of liquid. Since one end of the oil storage bag 23 is connected to the Tesla valve 22, the overflowing lubricating oil cannot flow out from the end of the Tesla valve 22, and a pressure valve is provided in the nozzle 25. When the pressure reaches a certain value, the overflowing lubricating oil in the oil storage bag 23 eventually passes through the oil injection pipe 24 and is sprayed from the nozzle 25 to the motor coil 7 and one end of the output shaft 3, thereby achieving lubrication of the inside of the motor body 1 and precise lubrication. The oil storage bag 23 is small in size, and only a small amount of oil needs to be injected through the oil filling port 6, so that it can be sprayed out at a fixed point from the nozzle 25, achieving precise lubrication and avoiding a large amount of waste caused by adding lubricating oil by traditional means.

[0053] As an embodiment of the present invention, refer to Fig. 9 An electromagnetic base plate 26 is provided at the bottom of the inner cavity of the motor body 1, and a mounting plate 27 is provided below the electromagnetic base plate 26. The mounting plates 27 are provided in three groups and are connected transversely. Reset springs 28 are connected below the mounting plates 27 at both sides, and a trigger switch head 29 is connected below the mounting plate 27 at the middle position. A trigger switch wire 30 is connected to the outside of the trigger switch head 29. A buzzer 31 is provided inside the motor body 1 and below the electromagnetic base plate 26.

[0054] After the lubricating oil lubricates the motor coil 7, the excess lubricating oil will inevitably fall and accumulate at the bottom of the inner cavity of the motor body 1, namely the electromagnetic base plate 26. As the lubricating oil continues to accumulate on the electromagnetic base plate 26, the weight of the electromagnetic base plate 26 increases accordingly, and the electromagnetic base plate 26 drives the mounting plate 27 clamped on its inner side to descend accordingly. The mounting plate 27 then drives the reset spring 28 and the trigger switch head 29 to descend synchronously, and the trigger switch head 29 then presses the trigger switch wire 30 inward, and the two sets of relative trigger switch wires 30 are immediately in contact with each other, and the internal circuit is immediately turned on, and the buzzer 31 then starts to alarm, emitting a sharp alarm sound to alert the staff.

[0055] As an embodiment of the present invention, refer to Figure 9-10A magnet 32 ​​is arranged below the outer shell of the motor body 1. The magnet 32 ​​is vertically installed and fits the outer shell of the motor body 1. A rotating shaft 33 is movably connected below the magnet 32. A fixed bracket 34 is arranged at the vertical connection between the rotating shaft 33 and the magnet 32.

[0056] When the circuit is turned on, the electromagnetic base plate 26 is energized synchronously to generate magnetism. Before the power is turned on, the electromagnetic base plate 26 is an ordinary plate without magnetism. As the electromagnetic base plate 26 is energized, it generates magnetism, which in turn generates relative adsorption on the magnet 32. The magnet 32 ​​is immediately attracted and rotates around the rotation axis 33. The magnet 32 ​​then deflects and loosens the contact with the motor body 1 shell, making it convenient for the staff to remove the rear shell and clean the accumulated lubricating oil to avoid damage to the motor body 1 caused by long-term accumulation of lubricating oil.

[0057] Working principle: When in use, the staff will add the lubricating oil into the interior of the motor body 1 from the oil filling port 6 in advance. The lubricating oil enters from the oil filling port 6 and first falls to the top of the oil dividing block 8. The top of the oil dividing block 8 is hemispherical, and the lubricating oil falling on it is separated and flows to the lower oil channels 9 on both sides, which cushions the fall of the lubricating oil and ensures the orderly fall of the lubricating oil, so that the tension of the lubricating oil is fully stretched; the lubricating oil then continues to fall from the lower oil channel 9 and passes through the oil containing channel 11. At this time, the built-in driving element of the rotating disc 12 starts to work, driving the rotating disc 12 to start rotating, and the rotating disc 12 then drives the installation axis 13 to do circular reciprocating motion , the installation axis 13 then drives the shaft 14 to start moving, and the shaft 14 then drives the knocking plate 15 connected thereto to do reciprocating motion, and the knocking plate 15 then synchronously reciprocates to knock the outer wall 16, and vibration is generated as the outer wall 16 is knocked, thereby increasing the flow speed of the lubricating oil. At the same time, it also prevents the lubricating oil from adhering to the outer wall 16 and causing subsequent secondary pollution; the lubricating oil finally passes through the oil outlet 17 to reach the drainage mechanism below it, and the driving axis 19 inside the drainage mechanism rotates synchronously, driving the drainage groove 20 to rotate synchronously in a circular shape, and the drainage groove 20 then receives the lubricating oil flowing down from the oil outlet 17, drives it, and reasonably distributes the lubricating oil When the drainage groove 20 is connected with the oil outlet channel 21, the lubricating oil received in the drainage groove 20 immediately enters the oil outlet channel 21, and enters the oil storage bag 23 from the Tesla valve 22 inside the oil outlet channel 21. The oil storage bag 23 stores the lubricating oil. When the lubricating oil in the oil storage bag 23 is full, as the Tesla valve 22 continues to deliver oil, more and more lubricating oil is stored in the oil storage bag 23. Since the Tesla valve 22 is a one-way valve (the Tesla valve 22 mentioned above is a one-way flow valve invented by the famous American scientist Nikola Tesla, without any moving parts, and can achieve one-way flow of airflow without inputting energy, it is a one-way gas flow valve , which is also applicable to the one-way flow of liquid). Since one end of the oil storage bag 23 is connected to the Tesla valve 22, the overflowing lubricating oil cannot flow out from the end of the Tesla valve 22, and a pressure valve is arranged in the nozzle 25. When the pressure reaches a certain value, the overflowing lubricating oil in the oil storage bag 23 finally passes through the oil injection pipe 24 and is sprayed from the nozzle 25 to the motor coil 7 and one end of the output shaft 3, thereby realizing the lubrication of the inside of the motor body 1 and realizing precise lubrication. Moreover, the volume of the oil storage bag 23 is relatively small. Only a small amount of oil needs to be injected through the oil filling port 6, and it can be sprayed out from the nozzle 25 at a fixed point to realize precise lubrication and avoid a large amount of waste caused by adding lubricating oil by traditional means.

[0058] After the lubricating oil lubricates the motor coil 7, the excess lubricating oil will inevitably fall and accumulate at the bottom of the inner cavity of the motor body 1, that is, the electromagnetic bottom plate 26. As the lubricating oil continues to accumulate on the electromagnetic bottom plate 26, the weight of the electromagnetic bottom plate 26 increases, and the electromagnetic bottom plate 26 drives the mounting plate 27 connected to its inner side to drop accordingly. The mounting plate 27 then drives the reset spring 28 and the trigger switch head 29 to drop synchronously, and the trigger switch head 29 then presses the trigger switch wire 30 inward, and the two sets of opposite trigger switch wires 30 are immediately in contact with each other, and the internal circuit is immediately turned on, and the buzzer 3 is turned on. 1 then starts to alarm, emitting a sharp alarm sound to remind the staff. At the same time, when the circuit is turned on, the electromagnetic bottom plate 26 is energized synchronously to generate magnetism. Before the power is turned on, the electromagnetic bottom plate 26 is an ordinary plate without magnetism. As the electromagnetic bottom plate 26 is energized to generate magnetism, it then produces relative adsorption on the magnet 32. The magnet 32 ​​is immediately attracted and rotates around the rotation axis 33 as the base point. The magnet 32 ​​then deflects and loosens the contact with the motor body 1 shell, making it convenient for the staff to remove the rear shell and clean the accumulated lubricating oil to avoid long-term accumulation of lubricating oil and damage to the motor body 1.
