Description

Technical Field

[0001] This invention relates to the field of speed reducer equipment technology, and more specifically to a speed reducer lubrication oil control system. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator.

[0003] The properties of the lubricating oil inside a speed reducer have a significant impact on its working condition and service life. During long-term continuous operation, the temperature of the lubricating oil inside the speed reducer will gradually increase. Currently, direct cooling is commonly used to dissipate heat from the lubricating oil. However, current cooling methods cannot precisely control the temperature of the lubricating oil flowing in the speed reducer's oil circuit, which may lead to excessively low lubricating oil temperature and increased viscosity, affecting its fluidity. Furthermore, the lubricating oil needs to be changed regularly, currently typically automatically after a certain period of use. This not only presents problems of untimely replacement but also complexity. Therefore, we propose a speed reducer lubricating oil control system. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] See attached document Figure 1-3 A speed reducer lubricating oil control system includes a speed reducer, an oil tank installed inside the speed reducer, an oil detection module installed inside the oil tank, a temperature control valve and an air cooler, and an oil replacement mechanism and an oil pump unit installed inside the oil tank.

[0041] The temperature control valve includes a temperature measurement unit and a valve control unit. The temperature control valve has three valve ports: A, B, and C. Valve port A is used to control the connection between the temperature control valve and the reducer, valve port B is used to control the connection between the oil tank and the temperature control valve, and valve port C is used to control the connection between the oil tank and the air cooler. All of them are electromagnetically controlled.

[0042] The reducer power supply, oil detection module and temperature control valve are connected to the oil replacement mechanism to obtain power supply and lubricating oil parameters, and transmit the parameters to the oil replacement mechanism to control the replacement of lubricating oil in the oil tank;

[0043] The temperature measurement unit acquires the temperature of the lubricating oil flowing out of the oil tank and transmits the parameters to the valve control unit to control whether the lubricating oil passes through the air cooler in the oil circuit.

[0044] The oil pump unit is designed with one unit on standby to control the continuous circulation of lubricating oil in the oil circuit, preventing equipment damage caused by the lubricating oil stopping flowing in the reducer if one unit fails.

[0045] In this embodiment, the lubricating oil cooling process is as follows:

[0046] The temperature measurement unit obtains the temperature of the lubricating oil flowing out of the oil tank. When the temperature is greater than 50℃, the valve control unit closes valve port B and opens valve port C, so that the oil is forced to cool down through the air cooler, and then the cooled oil enters the reducer.

[0047] When the oil temperature is below 40℃, the valve control unit closes valve C and fully opens valve B, allowing the oil to enter the reducer directly without passing through the cooler.

[0048] When the oil temperature is between 40℃ and 50℃, the valve control unit partially opens and closes valve ports C and B, allowing some oil to pass through the air cooler while the other part of the oil does not pass through the cooler. The oil mixes and enters the reducer oil tank at the same time. This system can better control the lubricating oil temperature, keeping the oil temperature entering the reducer within a smaller range and extending the service life of the reducer.

[0049] Lubricating oil replacement process: The oil detection module monitors various parameters of the lubricating oil in the oil tank, the temperature measurement unit obtains the temperature of the lubricating oil flowing out of the oil tank, and the running status data of the reducer. All of these are transmitted to the oil replacement mechanism. When the temperature measurement unit obtains that the temperature of the lubricating oil flowing out of the oil tank is between 40℃ and 50℃, and the reducer is stopped, if any of the lubricating oil measurement parameters exceeds the preset value, the oil replacement mechanism is activated. The lubricating oil in the oil tank is drained completely before new lubricating oil is added.

[0050] The lubricating oil is discharged at a temperature of 40℃-50℃, which can prevent the lubricating oil from becoming more viscous after cooling and can drain the lubricating oil better and faster. The oil is discharged when the reducer is stopped to prevent the amount of lubricating oil in the reducer from changing, which could lead to increased wear and damage. The signal transmission uses 485 lines or two buses, which makes the signal transmission voltage lower than 12V, effectively increasing the safety of the entire system.

[0051] The oil detection module includes a particle size detection unit, a pH value detection unit, a flash point detection unit, a depth detection unit, and a moisture detection unit;

[0052] The particle size detection unit is used to obtain the concentration parameters of lubricating oil particles in the oil tank and transmit the above parameters to the oil replacement mechanism;

[0053] Specifically, the particle detection unit uses a particle counter to determine the number of particles in the lubricating oil using the principle of light scattering. After the particle counter is powered on, it reads the particle concentration parameter of the lubricating oil in the oil tank and transmits this parameter to the oil replacement mechanism via a 485 line or two buses.

[0054] The pH value detection unit is used to obtain the pH value parameter of the lubricating oil in the oil tank and transmit the above parameter to the oil replacement mechanism;

[0055] Specifically, the pH value detection unit uses an acid-base degree sensor. After the acid-base degree sensor is powered on, it reads the pH value concentration parameter of the lubricating oil in the oil tank in real time and transmits the parameter to the oil replacement mechanism via a 485 line or two buses.

[0056] The flash point detection unit is used to obtain the thermal stability value parameters of the lubricating oil in the oil tank and transmit the above parameters to the oil replacement mechanism;

[0057] Specifically, the flash point detection unit uses a flash point detection sensor to monitor the flash point of the oil in real time and transmits this parameter to the oil replacement mechanism via a 485 line or two buses.

[0058] The depth detection unit is used to obtain the lubricating oil depth parameter in the oil tank and transmit the above parameter to the oil replacement mechanism;

[0059] Specifically, the depth detection unit adopts an internal float magnetic level gauge. After processing, the internal float can transmit the level change signal in real time, taking into account both alarm control and remote signal output functions. The oil parameters are transmitted to the oil replacement mechanism via 485 line or two bus. When the oil parameters are zero, the oil replacement mechanism empties the lubricating oil in the oil tank, and at this time, the oil inlet mechanism is controlled to introduce oil.

[0060] The moisture detection unit is used to obtain the water content parameter of the lubricating oil in the oil tank and transmit the above parameter to the oil replacement mechanism.

[0061] Specifically, the moisture detection unit utilizes the difference between the conductivity of water and the insulation of oil to measure the moisture content in the oil using the principle of resistance measurement.

[0062] Furthermore, the oil detection module is equipped with an oil quality sensor, which can be used to directly measure density, temperature, acid value, alkalinity, and moisture content, reducing the number of sensors in the oil tank by directly measuring multiple data points.

[0063] See attached document Figure 4-9 The oil replacement mechanism includes an oil bottle 2 inverted on top of the reducer body 1 and an oil inlet mechanism, a drive mechanism, and an oil outlet mechanism arranged sequentially from top to bottom inside the oil tank of the reducer body 1. The drive mechanism is used to control the opening of the valve chambers of the oil outlet mechanism and the oil inlet mechanism. When the valve chamber of the oil outlet mechanism opens, the lubricating oil in the oil tank of the reducer body 1 is discharged. When the valve chamber of the oil inlet mechanism opens, the lubricating oil stored in the oil bottle 2 falls into the oil tank of the reducer body 1 through its bottle opening.

[0064] In this embodiment, the cam 41 in the drive mechanism is eccentrically connected to the output shaft of the motor, and a lifting frame 42 is provided outside the cam 41. An upper push rod 43 and a lower push rod 44 are respectively provided on the upper and lower sides of the lifting frame 42. The lifting frame 42 rotates eccentrically, causing the upper push rod 43 and the lower push rod 44 to move up and down within the limiting plate on the outer wall. The upper push rod 43 is located directly below the oil inlet plug 32, and the lower push rod 44 is located directly above the oil outlet plug 52.

[0065] Specifically, the control system of the cam 41 motor is connected to the power supply of the reducer body 1, the oil detection module and the temperature control valve through two buses or a 485 line. When the reducer body 1 is stopped and the lubricating oil temperature is between 40℃ and 50℃, when the oil detection module detects that the data in the oil exceeds the preset value, the cam 41 motor starts. At this time, the cam 41 makes an eccentric motion around the motor shaft. At this time, the lifting frame 42 drives the upper push rod 43 and the lower push rod 44 to move up and down. Under the limit of the limit plate, the upper push rod 43 and the lower push rod 44 can make vertical reciprocating motion. When the cam 41 drives the lower push rod 44 to move downward, it will push the oil outlet plug 52 to move downward. When the cam 41 drives the upper push rod 43 to move upward, it will push the oil inlet plug 32 to move upward.

[0066] The oil outlet valve 51 is located on the lower side of the oil tank in the oil outlet mechanism. The oil outlet valve 51 is equipped with an oil outlet plug 52 that controls the opening and closing of the valve chamber. The bottom of the oil outlet plug 52 is equipped with a support spring 53 to support the oil outlet plug 52 and seal the valve chamber. A sealing ring is provided inside the valve to improve the sealing between the oil outlet plug 52 and the valve chamber. The bottom of the oil outlet valve 51 is sealed, and its side is connected to the oil outlet hose 54. The oil outlet hose 54 is set in the receiving cavity 55 at the bottom of the reducer body 1. One end of the receiving cavity 55 penetrates the side wall of the reducer body 1 so that the oil outlet hose 54 will not be pressed when pulled out through the penetration, thus preventing the oil outlet hose 54 from being crushed. It is fixed by multiple buckles 56 in the receiving cavity 55.

[0067] Specifically, one end of the oil outlet hose 54 is inserted into the waste oil storage container. The cam 41 rotates 90° clockwise, and the lower push rod 44 pushes the oil outlet plug 52 downward, causing the valve chamber of the oil outlet valve 51 to open. At this time, the oil in the oil tank inside the reducer body 1 flows into the waste oil container through the oil outlet valve 51 and the oil outlet hose 54. After the depth detection unit detects that the lubricating oil in the oil tank has been completely discharged, it controls the motor of the cam 41 to continue rotating the cam 41 clockwise by 180°. At this time, the lower push rod 44 moves upward, and the oil outlet plug 52 is reset under the support of the support spring 53, so that the oil outlet valve 51 is sealed to prevent the oil from flowing out through the oil outlet valve 51 when adding lubricating oil to the oil tank.

[0068] The oil inlet valve 31 is located on the upper side of the oil tank, and its valve cavity covers the outer wall of the inverted oil bottle 2. The oil inlet valve 31 is equipped with an oil inlet plug 32 that controls the opening and closing of the valve cavity. The insert rod 33 on the oil inlet plug 32 is located below the bottle opening of the oil bottle 2. The insert rod 33 has oil leakage grooves 34 on both sides that connect to its hollow cavity. The bottom of the connecting spring 35 in the oil inlet valve 31 abuts against the oil inlet plug 32, so that the oil inlet plug 32 and the valve cavity of the oil inlet valve 31 are sealed together.

[0069] Specifically, when cam 41 continues to rotate 180° clockwise, the upper push rod 43 moves upward, causing the oil inlet plug 32 to move upward. At this time, the valve chamber of the oil inlet valve 31 opens. When the oil inlet plug 32 moves upward, the connecting spring 35 is compressed, and the insert rod 33 is inserted upward into the oil bottle 2. At this time, the lubricating oil in the oil bottle 2 flows out through the oil leakage grooves 34 on both sides of the inner cavity of the insert rod 33, and then enters the oil tank through the valve chamber of the oil inlet valve 31. When the lubricating oil depth in the oil tank reaches a certain value, the depth detection unit controls cam 41 to rotate 90 degrees clockwise again. At this time, the lower push rod 44 moves downward, and the oil inlet plug 32 moves downward under the support of the connecting spring 35, so that the valve chamber of the oil inlet valve 31 is sealed by the oil inlet plug 32. At this time, the replacement of the lubricating oil in the oil tank is completed.

[0070] In this embodiment, a sealing film is provided at the mouth of the oil bottle 2. The film is made of one or more of the following materials: PP, PE, PVC and PET. The sealing film seals the oil bottle 2, allowing the lubricating oil inside the oil bottle 2 to be kept for a longer time. In addition, the body of the oil bottle 2 is made of transparent material, which makes it easy to observe the amount of lubricating oil inside the oil bottle 2 and further determine whether the lubricating oil in the oil tank has been automatically replaced.

[0071] In this embodiment, the insert rod 33 is not hollow, and its top is inclined to form an arc-shaped blade, which makes it easier and faster to puncture the sealing film at the mouth of the oil bottle 2, so that the lubricating oil in the oil bottle 2 can enter the oil tank through the oil inlet valve 31.

[0072] In this embodiment, the two side walls of the buckle 56 are elastic, and the middle part is provided with a cavity to accommodate the oil outlet hose 54. The distance between the narrowest points in the cavity is less than the diameter of the oil outlet hose 54. The buckle 56 fixes the oil outlet hose 54 to prevent the oil outlet hose 54 from being dragged and damaged.
