Description

Technical Field

[0001] The invention relates to the technical field of material surface treatment, and in particular to a friction reducing agent coating method and system. Background Art

[0002] The drive shaft is a transmission component in a vehicle that transmits power from the engine or motor to the drive wheel. During the transmission process, the drive shaft needs to rotate around the central axis of the drive shaft. The wheel hub bearing is a component used to support the drive shaft and the drive wheel in the vehicle. During the driving process of the vehicle, the end face of the drive shaft outer ball cage will continue to contact and rub against the wheel hub bearing. At present, a friction reducer is usually applied to the end face of the drive shaft outer ball cage to reduce the friction coefficient between the contact surfaces and weaken or eliminate friction noise.

[0003] When applying the friction reducer to the end face of the drive shaft outer ball cage, in order to facilitate the adhesion of the friction reducer, the drive shaft outer ball cage needs to be placed on the conveyor belt with the splines of the drive shaft outer ball cage on top. However, before applying the friction reducer to the end face of the drive shaft outer ball cage, pretreatment such as degreasing and water washing is required. During the water washing process, water may be stored in the installation holes of the splines. When applying the friction reducer, the water in the installation holes may spill onto the end face of the drive shaft outer ball cage where the friction reducer is applied, resulting in the friction reducer being unable to be tightly and firmly connected to the end face of the drive shaft outer ball cage.

At the same time, the gas sprayed from the first air port will not blow back the liquid coming out of the mounting hole. If there is still liquid on the side of the sleeve body close to the spline and in the mounting hole after the drying treatment, the second air blowing treatment can completely remove the liquid to the point where it does not affect the coating of the friction reducer; at the same time, the temperature of the workpiece after drying is high, which is not conducive to the coating of the friction reducer. This method can also reduce the temperature of the workpiece to a suitable temperature range for the coating of the friction reducer, which can further improve the efficiency and quality of the friction reducer coating.

[0063] In this embodiment, the friction reducing agent coating system may include a transmission component 01, a phosphating component 08, a cleaning component 02, a first air blowing component 03, a drying component 04, a second air blowing component 05, a coating component 06, a curing component 07, and a workpiece 09. The phosphating component 08, the cleaning component 02, the first air blowing component 03, the drying component 04, the second air blowing component 05, the coating component 06, and the curing component 07 may be detachably connected to the transmission component 01 in sequence along the length direction of the transmission component 01. The workpiece 09 may pass through the phosphating component 08, the cleaning component 02, the first air blowing component 03, the drying component 04, the second air blowing component 05, the coating component 06, and the curing component 07 in sequence under the drive of the transmission component 01. Figure 3 , Figure 4As shown, the first blowing assembly 03 may include a first support portion 31 and a first blowing port 32. The first support portion 31 may be detachably connected to the transmission assembly 01. The first blowing port 32 may be detachably connected to the first support portion 31. The second blowing assembly 05 may include a second support portion 51, a second blowing port 52, and a side blowing unit 53. The second support portion 51 is detachably connected to the transmission assembly 01. The second blowing port 52 and the side blowing unit 53 are detachably connected to the second support portion 51, respectively.

[0064] During the driving process of the vehicle, the transmission shaft will transmit the power of the engine or motor to the driving wheel, and the wheel hub bearing supporting the driving wheel and the transmission shaft will rub against the end face of the outer ball cage of the driving shaft. Therefore, in order to make the end face of the outer ball cage of the transmission shaft, that is, the end face of the workpiece 09 more wear-resistant, a friction reducer is usually applied to the end face of the workpiece 09. Before applying the friction reducer, the workpiece 09 needs to be pre-treated to ensure the good quality of the friction reducer coating. Since the spline 92 of the workpiece 09 is provided with a mounting hole 93, liquid may be stored in the mounting hole 93 during the pre-treatment process. When applying the friction reducer, the liquid is easy to spill on the end face of the workpiece 09, resulting in poor adhesion of the friction reducer. Therefore, a friction reducer coating method is proposed.

[0065] like Figure 1 As shown, the friction reducing agent coating method may include steps S10 to S50, and each step may be described in detail below.

[0066] Step S10, pretreatment of the workpiece 09 is completed based on the phosphating component 08 and the cleaning component 02. The pretreatment can make the surface of the workpiece 09 clean enough for the antifriction agent coating, but there is residual liquid after the cleaning component cleans the workpiece 09. Therefore, the transmission component 01 can move the workpiece 09 to the working area of ​​the first blowing component 03, and perform the first blowing treatment on the workpiece 09 to reduce the liquid on the workpiece 09. Among them, the first blowing treatment can include the first blowing port 32 of the first blowing component 03 spraying gas in the direction of the mounting hole 93 of the workpiece 09. The direction of the gas sprayed by the first blowing port 32 is at a first set angle with the central axis of the mounting hole 93. The first set angle can be 3° to 5°, which can discharge the liquid in the mounting hole 93 to the external space of the mounting hole 93. At the same time, the gas sprayed by the first blowing port 32 will not blow back the liquid coming out of the mounting hole 93, which can prepare for the subsequent steps. Figure 5 , Figure 6As shown, the workpiece 09 may include a sleeve 91, a spline 92, and a mounting hole 93. The sleeve 91 may be configured as a cylindrical body. The spline 92 may be fixedly connected to one side of the sleeve 91 along the axial direction. The diameter of the spline 92 may be smaller than the diameter of the sleeve 91. The mounting hole 93 may be recessed from the end of the spline 92 away from the sleeve 91 toward the direction close to the sleeve 91. When the workpiece 09 is pretreated, the end of the sleeve 91 away from the spline 92 abuts against the transmission component 01, and the spline 92 is above the sleeve 91. The spline 92 and the side of the sleeve 91 close to the spline 92 need to cooperate with other components when the vehicle is driving. This method can prevent the spline 92 and the side of the sleeve 91 close to the spline 92 from colliding with the transmission component 01, ensuring the stable driving of the vehicle after the workpiece 09 is loaded; at the same time, the friction reducer is applied to the side of the sleeve 91 close to the spline 92, and the friction reducer is liquid. This method can prevent the friction reducer from flowing after being applied to the side of the body close to the spline 92, which is convenient for the subsequent curing of the friction reducer and improves the efficiency of the friction reducer coating. The first air port 32 can be higher than the mounting hole 93, so that the gas sprayed by the first air port 32 can efficiently discharge the liquid in the mounting hole 93 to the external space of the mounting hole 93.

[0067] Step S20, based on the completion of the first blowing treatment, there is still liquid on the side of the sleeve 91 close to the spline 92 and in the mounting hole 93, which will have a negative impact on the adhesion of the friction reducer during the coating process. Therefore, the transmission component 01 can move the workpiece 09 to the space surrounded by the drying component 04, so that the drying component 04 increases the temperature of the workpiece 09 and dries the workpiece 09, thereby evaporating the liquid on the side of the sleeve 91 close to the spline 92 and in the mounting hole 93, which can reduce the negative impact of the liquid on the coating of the friction reducer.

[0068] Step S30, based on the completion of the drying process, the transmission component 01 can move the workpiece 09 to the space surrounded by the second blowing component 05, and perform the second blowing process on the workpiece 09. If there is still liquid on the side of the sleeve 91 close to the spline 92 and the mounting hole 93 after the drying process, the second blowing process can completely remove the liquid to the point where it does not affect the coating of the friction reducer; at the same time, the temperature of the workpiece 09 after drying is high, which is not conducive to the coating of the friction reducer. This method can also reduce the temperature of the workpiece 09 to a suitable temperature range for the coating of the friction reducer, which can further improve the efficiency and quality of the coating of the friction reducer. Among them, the second blowing process can include the second blowing port 52 of the second blowing component 05 spraying gas toward the mounting hole 93, and the side blowing unit 53 of the second blowing component 05 spraying gas toward the side of the sleeve 91 close to the spline 92. The direction of the gas sprayed by the second blowing port 52 is at a second set angle with the central axis of the mounting hole 93. The second blowing port 52 is higher than the mounting hole 93. The second set angle can be 3° to 5°, which can discharge the liquid in the mounting hole 93 to the external space of the mounting hole 93. At the same time, the gas ejected by the second air port 52 will not blow the liquid out of the mounting hole 93 back, so as to prepare for the subsequent steps. The side air blowing unit 53 can thoroughly clean the liquid on the side of the sleeve 91 close to the spline 92 until it does not affect the coating of the friction reducer, and can improve the coating quality of the friction reducer. In this way, at the same time, the first air port 32 can blow the liquid in the mounting hole 93 of one workpiece 09 to separate from the mounting hole 93, and the second air port 52 can blow the liquid in the mounting hole 93 of another workpiece 09 to separate from the mounting hole 93, which has high production efficiency. Furthermore, after the second air outlet 52 blows the liquid in the mounting hole 93 to separate from the mounting hole 93, even if the liquid spills on the side of the sleeve 91 close to the spline 92, since the sleeve 91 has a higher temperature after heating and the surface area of ​​the liquid after spilling is larger, it can evaporate more quickly or be blown away from the workpiece 09 by the side air blowing unit 53. Then, when the friction reducer is coated on the side of the sleeve 91 close to the spline 92, the adhesion effect of the friction reducer is better.

[0069] Step S40, based on the completion of the second air blowing treatment, it can be determined that there is no liquid on the side of the sleeve 91 close to the spline 92, and the liquid in the mounting hole 93 will not spill onto the side of the sleeve 91 close to the spline 92 during the process of coating the friction reducer. The transmission component 01 can move the workpiece 09 into the space surrounded by the coating component 06, and perform a friction reducer coating treatment on the side of the sleeve 91 of the workpiece 09 close to the spline 92.

[0070] Step S50, based on the completion of the coating process, the transmission component 01 can move the workpiece 09 into the space surrounded by the curing component 07, and let the curing component 07 perform a curing process on the workpiece 09, so that the friction reducer coated on the side of the sleeve 91 close to the spline 92 is cured, so that the friction reducer can be attached to the side of the sleeve 91 close to the spline 92 for a long time and stably.

[0071] In this embodiment, when the workpiece 09 is subjected to the first air blowing treatment, the first air port 32 can spray gas toward the mounting hole 93 along the normal of the moving direction of the workpiece 09 on the transmission component 01, so as to prevent the gas sprayed by the first air port 32 from blowing the liquid in the mounting hole 93 of one workpiece 09 into the mounting hole 93 of another workpiece 09, thereby improving the efficiency of removing the liquid in the mounting hole 93 and further improving the efficiency of applying the friction reducer.

[0072] In this embodiment, step S30 may include steps S31 to S33, and each step may be described in detail below.

[0073] Step S31, based on the completion of the drying process, the transmission component 01 can move the workpiece 09 to the space surrounded by the second blowing component 05, and let the second blowing port 52 of the second blowing component 05 spray gas in the direction of the mounting hole 93, so that the liquid in the mounting hole 93 can be discharged to the external space of the mounting hole 93, to prevent the liquid in the mounting hole 93 from spilling to the side of the sleeve body 91 close to the spline 92 when the friction reducer is applied to the side of the sleeve body 91 close to the spline 92.

[0074] Step S32, based on the second air blowing component 05 spraying gas for the first set time toward the mounting hole 93, the side air blowing unit 53 can spray gas toward the side of the sleeve 91 close to the spline 92, and the first set time can be half of the total duration of the second air blowing treatment. When the second air blowing component 05 sprays gas toward the mounting hole 93, the liquid in the mounting hole 93 may spill onto the side of the sleeve 91 close to the spline 92, and the side air blowing unit 53 can thoroughly clean the liquid on the side of the sleeve 91 close to the spline 92. At the same time, in this way that the second air blowing port 52 works first and the side air blowing unit 53 works later, after the second air blowing port 52 discharges the liquid in the mounting hole 93, it will not be affected by other airflows and then return to the mounting hole 93, which can improve the efficiency of removing the liquid on the workpiece 09, thereby improving the efficiency of the friction reducer coating and the coating quality.

[0075] Step S33, based on the side air blowing unit 53 spraying gas for a second set time toward the side of the sleeve 91 close to the spline 92, it can be determined that there is no liquid on the side of the sleeve 91 close to the spline 92 at this time, and the side of the sleeve 91 of the workpiece 09 close to the spline 92 can be coated with a friction reducer, and the absence of liquid has a negative impact on the coating of the friction reducer, ensuring that the friction reducer is tightly connected to the side of the sleeve 91 close to the spline 92. The second set time can be the difference between the total duration of the second air blowing treatment and the first set time.

[0076] In this embodiment, when the workpiece 09 is subjected to the second air blowing treatment, the second air port 52 can spray gas toward the mounting hole 93 along the normal of the moving direction of the workpiece 09 on the transmission component 01, so as to prevent the gas sprayed from the second air port 52 from blowing the liquid in the mounting hole 93 of one workpiece 09 into the mounting hole 93 of another workpiece 09, thereby improving the efficiency of removing the liquid in the mounting hole 93 and further improving the efficiency of applying the friction reducer.

[0077] In this embodiment, step S40 includes steps S41 to S46, and each step will be described in detail below.

[0078] The friction reducing agent coating system may further include a coating component 06. A storage unit 61, a coating unit 62, a rotating table 63, a first clamping unit 64, a second clamping unit 65, a mechanical arm 66, and a friction reducing agent. The first clamping unit 64 and the second clamping unit 65 may be detachably connected to the mechanical arm 66, respectively. The first clamping unit 64 may be used to clamp the workpiece 09. The second clamping unit 65 may be used to clamp the coating unit 62. The mechanical arm 66 may drive the first clamping unit 64 and the second clamping unit 65 to move according to a predetermined program. The rotating table 63 may be disposed on one side of the transmission component 01. The storage unit 61 may be disposed on one side of the rotating table 63. The friction reducing agent may be contained in the storage unit 61, and the storage unit 61 may stir the friction reducing agent.

[0079] Step S41, based on the completion of the second air blowing process, the robot arm 66 drives the first clamping part 64 to move the workpiece 09 to the rotating table 63. The side of the sleeve 91 away from the spline 92 is in contact with the rotating table 63. When the friction reducer is subsequently applied to the side of the sleeve 91 close to the spline 92, the friction reducer can be relatively stably stayed on the side of the sleeve 91 close to the spline 92, waiting for the friction reducer to solidify, so that the connection between the friction reducer and the sleeve 91 is stable. The rotating table 63 can be set on one side of the transmission component 01.

[0080] Step S42, based on the workpiece 09 being located on the rotating platform 63, the robot arm 66 drives the second clamping part 65 to grab the brushing part 62, and the brushing part 62 can be a brush that does not shed hair and has fine hair.

[0081] In step S43 , the second clamping portion 65 grasps the coating portion 62 and drives the coating portion 62 to move toward the friction reducing agent.

[0082] In step S44 , the friction reducing agent is attached to the surface of the coating part 62 based on the contact between the coating part 62 and the friction reducing agent, and then the coating part 62 is driven to move toward the sleeve body 91 .

[0083] Step S45, based on the abutment between the coating part 62 and the side of the sleeve 91 close to the spline 92, the friction reducer on the coating part 62 adheres to the side of the sleeve 91 close to the spline 92, and then the rotating table 63 can drive the sleeve 91 to rotate around the central axis of the sleeve 91, so that all parts of the sleeve 91 along the circumferential direction close to the spline 92 can complete the coating of the friction reducer; at the same time, this method can also avoid the robot arm 66, the first clamping part 64, and the second clamping part 65 from colliding with the workpiece 09 respectively under the premise of reducing the accuracy requirements of the robot arm 66.

[0084] Step S46, after driving the sleeve 91 to rotate around the central axis of the sleeve 91 by a set angle (the set angle can be 360° or 720°) based on the rotating table 63, it can be determined that all parts of the sleeve 91 along the circumferential direction close to the spline 92 are evenly coated with a sufficient amount of friction reducer, and then the workpiece 09 can be cured to form a stable connection between the friction reducer and the sleeve 91.

[0085] In this embodiment, the friction reducer can be placed in the storage portion 61. The friction reducer storage portion 61 drives the friction reducer to rotate around the central axis of the storage portion 61, and the rotation speed can be 66 revolutions per minute, which can prevent the friction reducer from settling, so that the friction reducer applied to the side of the sleeve body 91 close to the spline 92 can fully reduce the friction coefficient of the side of the sleeve body 91 close to the spline 92.

[0086] In this embodiment, step S10 may include steps S11 to S12, and each step may be described in detail below.

[0087] The cleaning assembly 02 may include a cleaning chamber 21 and a cleaning unit 22; the cleaning chamber 21 may be detachably connected to the transmission assembly 01. The cleaning unit 22 may be detachably connected to the cleaning chamber 21. The cleaning unit 22 may be disposed in a space surrounded by the cleaning chamber 21. The cleaning unit 22 may clean the surface of the workpiece 09 to prevent foreign matter from negatively affecting the friction reducing agent coating.

[0088] Step S11, based on the completion of the initial processing of the workpiece 09, foreign matter may adhere to the surface of the sleeve 91 during the initial processing, which will affect the effect of the friction reducer adhering to the surface of the sleeve 91. Therefore, the transmission component 01 can then move the workpiece 09 into the cleaning chamber 21 to clean the foreign matter.

[0089] Step S12, based on the workpiece 09 moving into the cleaning chamber 21, the cleaning unit 22 can clean the workpiece 09. The cleaning unit 22 sprays the cleaning liquid from top to bottom toward the workpiece 09, and the cleaning liquid can flow from top to bottom on the workpiece 09 by using its weight. When the cleaning liquid flows, foreign matter can be attached to the cleaning liquid and separated from the workpiece 09, so that the friction reducer can be applied to the side of the sleeve 91 close to the spline 92 and can be firmly connected to the workpiece 09.

[0090] In this embodiment, step S11 may include steps S111 to S117 , and each step may be described in detail below.

[0091] The phosphating component 08 may include a degreasing chamber 81, a water washing chamber 82, a surface conditioning chamber 83, a phosphating chamber 84, a spraying chamber 85, and a drying chamber 86; the degreasing chamber 81, the water washing chamber 82, the surface conditioning chamber 83, the phosphating chamber 84, the spraying chamber 85, and the drying chamber 86 may be detachably connected to the transmission component 01 in sequence along the moving direction of the workpiece 09 on the transmission component 01.

[0092] Step S111, based on the surface treatment instruction trigger, the transmission component 01 can move the workpiece 09 into the degreasing chamber 81, and the degreasing chamber 81 can use degreasing liquid to remove the grease remaining on the surface of the workpiece 09, which can prevent the friction reducer from being coated on the side of the sleeve 91 close to the spline 92.

[0093] Step S112, after the degreasing treatment of the workpiece 09 is completed in the degreasing chamber 81, the degreasing liquid remaining on the surface of the workpiece 09 will form a covering film, affecting the phosphating effect and reducing the adhesion of the friction reducer. Therefore, the transmission component 01 can move the workpiece 09 to the water washing chamber 82, and the water washing chamber 82 can wash the degreasing liquid to ensure the stable adhesion of the friction reducer.

[0094] Step S113, based on the completion of the water washing treatment of the workpiece 09 in the water washing chamber 82, the transmission component 01 can move the workpiece 09 to the surface adjustment chamber 83, and the surface adjustment chamber 83 can adjust the surface of the workpiece 09, change the microscopic state of the metal surface, so as to accelerate phosphating and promote the formation of a phosphating salt film with fine crystals, uniformity, and density during the phosphating process.

[0095] Step S114, based on the surface adjustment bin 83, the surface adjustment processing of the workpiece 09 is completed, and the transmission component 01 can move the workpiece 09 to the phosphating bin 84. The phosphating bin 84 can provide protection for the workpiece 09 and prevent the workpiece 09 from being corroded to a certain extent.

[0096] Step S115, based on the phosphating treatment of the workpiece 09 in the phosphating chamber 84 being completed, the transmission component 01 moves the workpiece 09 to the spraying chamber 85, and the spraying chamber 85 can spray paint on the surface of the workpiece 09, which can further prevent the workpiece 09 from rusting.

[0097] Step S116, based on the completion of the spraying process of the workpiece 09 by the spraying chamber 85, the transmission component 01 moves the workpiece 09 to the drying chamber 86, and the drying chamber 86 can quickly solidify the paint sprayed on the workpiece 09 by the spraying chamber 85.

[0098] Step S117, based on the drying process of the workpiece 09 in the drying chamber 86, the transmission component 01 moves the workpiece 09 to the cleaning chamber 21. When the paint of the workpiece 09 after spraying is solidified in the high-temperature drying chamber 86, there are a lot of foreign matter such as dust in the drying chamber 86, which will adhere to the surface of the workpiece 09. After the workpiece 09 is moved to the cleaning chamber 21, the foreign matter on the surface of the workpiece 09 can be separated from the workpiece 09, thereby avoiding the negative impact of the friction reducer when it is applied to the side of the sleeve 91 close to the spline 92.

[0099] In this embodiment, step S30 may include steps S31 to S33, and each step may be described in detail below.

[0100] The drying assembly 04 may include a drying chamber 41 and a drying unit 42; the drying chamber 41 may be detachably connected to the transmission assembly 01. The drying unit 42 may be detachably connected to the drying chamber 41. The drying unit 42 may be disposed in a space surrounded by the drying chamber 41.

[0101] Step S31 , based on the completion of the first air blowing process, the transmission component 01 can move the workpiece 09 into the drying chamber 41 .

[0102] Step S32, based on the workpiece 09 being in the drying chamber 41, the drying section 42 can be heated to a set temperature to evaporate the liquid remaining on the surface of the workpiece 09 after the first air blowing treatment. The drying chamber 41 can prevent the heat emitted by the drying section 42 from dissipating, thereby improving the drying efficiency.

[0103] In step S33, based on the drying time set by the drying unit 42, a second air blowing treatment can be performed on the workpiece 09 to further remove the liquid on the surface of the workpiece 09, and the temperature of the workpiece 09 can be reduced to a suitable range for applying the friction reducer, thereby improving the efficiency of applying the friction reducer.

[0104] In this embodiment, a friction reducing agent coating system is provided, and the friction reducing agent coating system is applied to any of the friction reducing agent coating methods in the above embodiments, such as Figure 2As shown, the friction reducer coating system may include a transmission component 01, a phosphating component 08, a cleaning component 02, a first air blowing component 03, a drying component 04, a second air blowing component 05, a coating component 06, a curing component 07, and a workpiece 09. The phosphating component 08 can be detachably connected to the transmission component 01. The cleaning component 02 can be detachably connected to the transmission component 01. The phosphating component 08 can phosphate the side of the sleeve 91 close to the spline 92, so that after the friction reducer is coated on the side of the sleeve 91 close to the spline 92, the friction reducer is firmly connected to the sleeve 91. The cleaning component 02 can separate foreign matter generated on the surface of the workpiece 09 after the phosphating component 08 treats the workpiece 09 from the workpiece 09. The phosphating component 08 and the cleaning component 02 can pre-treat the workpiece 09 so that the friction reducer is tightly connected to the side of the sleeve 91 close to the spline 92. As shown Figure 4 , Figure 3As shown, the first blowing assembly 03 may include a first support portion 31 and a first blowing port 32. The first support portion 31 may be detachably connected to the transmission assembly 01. The first blowing port 32 may be detachably connected to the first support portion 31. The first blowing port 32 may spray gas toward the mounting hole 93, and the direction of the gas sprayed by the first blowing port 32 forms a first set angle with the central axis of the mounting hole 93, and the first set angle may be 3° to 5°, so that the liquid in the mounting hole 93 may be discharged to the external space of the mounting hole 93, and the gas sprayed by the first blowing port 32 may not blow the liquid out of the mounting hole 93 back. The drying assembly 04 may be detachably connected to the transmission assembly 01, and the workpiece 09 may be moved to the space surrounded by the drying assembly 04. The drying assembly 04 may increase the temperature of the workpiece 09 and dry the workpiece 09, so that the liquid on the side of the sleeve 91 close to the spline 92 and the mounting hole 93 may evaporate, and the negative impact of the liquid on the coating friction reducer may be reduced. The second air blowing assembly 05 may include a second support portion 51, a second air blowing port 52, and a side air blowing unit 53. The second support portion 51 is detachably connected to the transmission assembly 01. The second air blowing port 52 and the side air blowing unit 53 are detachably connected to the second support portion 51, respectively. The second air blowing port 52 can discharge the liquid in the mounting hole 93 to the external space of the mounting hole 93, and the gas ejected by the second air blowing port 52 will not blow the liquid out of the mounting hole 93 back, so as to prepare for the subsequent steps. The side air blowing unit 53 can thoroughly clean the liquid on the side of the sleeve body 91 close to the spline 92 until it does not affect the coating of the friction reducer, and can improve the coating quality of the friction reducer. The coating assembly 06 can be detachably connected to the transmission assembly 01, and the friction reducer is applied to the side of the sleeve body 91 close to the spline 92. The curing assembly 07 can be detachably connected to the transmission assembly 01, so that the friction reducer on the side of the sleeve body 91 close to the spline 92 is solidified, and the stability of the connection between the friction reducer and the sleeve body 91 is maintained. The phosphating assembly 08, the cleaning assembly 02, the first supporting part 31, the drying assembly 04, the second supporting part 51, the coating assembly 06, and the curing assembly 07 can be sequentially arranged in intervals along the length direction of the transmission assembly 01. Figure 5 , Figure 6 As shown, the workpiece 09 may include a sleeve 91, a spline 92, and a mounting hole 93. The sleeve 91 is configured as a cylindrical body. The spline 92 may be fixedly connected to one side of the sleeve 91 along the axial direction. The diameter of the spline 92 may be smaller than the diameter of the sleeve 91, so that the end of the sleeve 91 close to the spline 92 can be matched with other parts after being loaded. The mounting hole 93 may be recessed from the end of the spline 92 away from the sleeve 91 toward the sleeve 91, so that the mounting hole 93 can be matched with other parts after the workpiece 09 is loaded and used.

[0105] The friction reducing agent coating system may include a working state. The working state may include that one end of the sleeve 91 away from the spline 92 abuts against the transmission component 01, the spline 92 is above the sleeve 91, and the side of the sleeve 91 close to the spline 92 needs to cooperate with other components during the driving process of the vehicle, and the spline 92 also needs to cooperate with other components. This method can prevent the matching surface from being damaged, and this method can also make the friction reducing agent more stable during the curing process when the friction reducing agent is applied, and the quality of the friction reducing agent coating can be improved. The first air blowing port 32 can be higher than the mounting hole 93, and the second air blowing port 52 can be higher than the mounting hole 93, so that the air flow can smoothly enter the mounting hole 93 and blow the liquid in the mounting hole 93 out to the external space of the mounting hole 93. The transmission component 01 drives the workpiece 09 to pass through the phosphating component 08, the cleaning component 02, the first support part 31, the drying component 04, the second support part 51, the coating component 06, and the curing component 07 in sequence, so that the friction reducing agent coating can be carried out efficiently and with high quality on the side of the sleeve 91 close to the spline 92 according to the predetermined process.

[0106] In other embodiments, the curing assembly 07 may include a curing chamber 71 and a curing part 72; the curing chamber 71 may be detachably connected to the transmission assembly 01. The curing part 72 may be detachably connected to the curing chamber 71. The curing part 72 may be disposed in a hollow cavity of the curing chamber 71. The curing part 72 may be heated to control the temperature of the workpiece 09 in the curing chamber 71 at 60±5°C, so as to ensure that the friction reducer does not generate cracks after curing, and that the friction reducer is tightly connected to the sleeve 91 on the side close to the spline 92.
