Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of power devices, in particular to a deceleration power system. BACKGROUND

[0002] The reducer plays a role in matching the rotating speed and transmitting the torque between the prime mover and the working machine or the actuator. The purpose of using the reducer is to reduce the rotating speed of the motor and increase the torque. The reducer is widely used in various fields and aspects of industry, with high level and high performance. There are various types of reducers with different models and different purposes.

[0003] The reducer is usually composed of multiple sets of transmission gears. Air is mixed into the lubricating oil during the addition of lubricating oil. Due to the consideration of dust prevention effect, the existing reducer is generally a closed cavity structure, and the mixed air cannot be removed. The air bubbles formed by the mixed air can cause pitting damage to the reducer parts and reduce the service life of the equipment. On the other hand, when the temperature of the lubricating oil rises, the air will accelerate the oxidation and reduce the service life of the lubricating oil. At the same time, due to the closed setting of the reducer, the expansion of the lubricating oil will increase the internal air pressure when the temperature of the lubricating oil rises. At this time, due to the pressure difference, the lubricating oil will leak through the shaft gap.

[0004] And because the existing reducer is a one-piece closed setting, when the reducer and the motor are integrated into an integrated structure, it is not convenient to overhaul the motor bearing. SUMMARY

[0062] like Figures 1-11 As shown, the deceleration power system disclosed herein includes:

[0063] The power unit 10 is specifically an electric motor structure and has a first output shaft for outputting power.

[0064] The speed reducer unit 20 has its power input end connected to the first output shaft via a power connection mechanism 30, and has a second output shaft 201 for outputting power. For example, the internal structure of the speed reducer unit 20 is as follows: Figure 2 As shown, the device includes a reducer housing with an internal cavity. An intermediate gear 202 is rotatably connected inside the cavity, and three planetary gears 203 are arranged around the outer periphery of the intermediate gear 202. The intermediate gear 202 meshes with the three planetary gears 203, and all three planetary gears 203 are rotatably connected to the cavity. The inner wall of the cavity is also provided with a rotatable internal gear ring 204. The axes of the three planetary gears 203 are all connected to a star-shaped arm 205. A second output shaft 201 is provided at the center of the star-shaped arm 205, which is exposed outside the reducer unit 20. The second output shaft 201 is used to connect to external equipment. The reduction output of power to the power unit 10 is achieved through the aforementioned planetary gear set 203.

[0065] The oil supplementing mechanism 40 comprises an oil storage container 401, a circulating oil path 402, and an exhaust assembly 403;

[0066] The oil storage container 401 is in a cuboid box structure, and an oil storage cavity 4011 for storing lubricating oil is formed in the inside of the oil storage container 401. An exhaust hole 4012 is formed in the upper portion of the oil storage container 401 and communicates with the oil storage cavity 4011.

[0067] The oil storage cavity 4011 is connected with the inside of the speed reducer set 20 through the circulating oil path 402, so that the lubricating oil can flow between the speed reducer set 20 and the oil storage container 401 to lubricate the internal components of the speed reducer set 20.

[0068] The exhaust assembly 403 specifically comprises a pressing plate 4031 slidingly arranged on the upper portion of the oil storage cavity 4011. The pressing plate 4031 is specifically slidingly connected with the oil storage container 401, so that the pressing plate 4031 can slide up and down in the oil storage cavity 4011. When the oil storage cavity 4011 stores lubricating oil, the pressing plate 4031 can press down to generate pressure on the lubricating oil, so as to extrude the air in the lubricating oil outward and discharge the air outward through the exhaust hole 4012 in the upper portion.

[0069] Further, in the embodiment, in order to facilitate driving the pressing plate 4031 to slide up and down, the exhaust assembly 403 further comprises a first driving member 4032 which is linked with the pressing plate 4031 and is used for driving the pressing plate 4031 to slide up and down. In the embodiment, the first driving member 4032 is specifically an electric telescopic rod arranged on the top of the oil storage container 401. A connecting block is connected to the telescopic end of the electric telescopic rod. The connecting block is horizontally arranged, and push rods are vertically fixed to the two ends of the connecting block. The lower ends of the two push rods extend into the oil storage container 401 and are connected with the two pressing plates 4031 respectively. Thus, the pressing plate 4031 can be driven to slide up and down by the extension and retraction of the electric telescopic rod. In other alternative embodiments, the first driving member 4032 can also be selected from a telescopic cylinder, a motor and other commonly used driving members.

[0070] In order to enable the lubricating oil to form effective circulating flow on both sides of the oil storage cavity 4011, a partition plate 4013 extending in the vertical direction is arranged in the middle portion of the oil storage cavity 4011. An oil passing hole is formed in the middle portion of the partition plate 4013. The lubricating oil flows between the two sides of the oil storage cavity 4011 from the oil passing hole position in the middle portion of the partition plate 4013 under the blocking action of the partition plate 4013 at the two ends, so as to form stable circulating flow.

[0071] The number of the pressing plates 4031 is two, and the two pressing plates 4031 are arranged horizontally on the left and right sides of the partition plate 4013 respectively, so as to effectively extrude and discharge air from the lubricating oil on both sides.

[0072] In order to facilitate the extrusion of air to gather upward discharge, the bottom surface of the pressing plate 4031 is formed with an upwardly recessed arc-shaped groove, the arc-shaped groove is recessed from both sides of the width direction of the pressing plate 4031 to the middle part, the depth gradually increases, and the groove bottom of the arc-shaped groove is formed at the middle position of the pressing plate 4031, so that when the air in the extruded lubricating oil is extruded, the air can be collected to the groove bottom position of the middle part of the arc-shaped groove from both sides, and it is convenient to discharge.

[0073] In order to filter out impurities in the discharged air and avoid pollution of the air, the bottom of the arc-shaped groove is formed with a filter hole extending upwardly through the bottom, and an air filter membrane 4033 is embedded in the filter hole for filtering impurities in the discharged air.

[0074] The lower part of the pressing plate 4031 is connected with a pressure sensor for sensing the internal pressure of the oil storage cavity 4011 during the pressing process, so as to supplement the lubricating oil or adjust the position of the pressing plate 4031 according to the internal pressure, and adjust the internal pressure of the oil storage cavity 4011 to maintain the internal pressure within a safe range.

[0075] In order to make the pressing plate 4031 extrude the lubricating oil fully and avoid the lubricating oil flowing from the gap between the pressing plate 4031 and the inside of the oil storage cavity 4011 during the extrusion process, a sealing strip made of rubber material is attached to the outer edge of the pressing plate 4031 in this embodiment, the sealing strip is filled between the outer edge of the pressing plate 4031 and the inner wall of the oil storage cavity 4011, so as to form a relatively sealed structure between the pressing plate 4031 and the oil storage cavity 4011, so that the pressing plate 4031 can ensure that the lubricating oil is extruded fully when it is pressed, and then the air in the lubricating oil can be fully discharged.

[0076] Further, in this embodiment, the power unit 10 is arranged at one end of the speed reducer unit 20, and the power unit 10 is fixed with a square connecting plate at the end connected with the speed reducer unit 20, the connecting plate is fixedly connected with the power unit 10 through bolts to form a detachable structure. The speed reducer unit 20 is connected on the other side of the connecting plate.

[0077] The end surface shape of the power unit 10 and the speed reducer unit 20 is a matching rectangle, and the oil storage container 401 is arranged at the end of the power unit away from the speed reducer unit 20, so that the overall structure of the speed reduction power system is compact.

[0078] The oil storage container 401 specifically includes a shell 4014 and an end cover 4015, the shell 4014 is formed with an opening at the end away from the power unit 10, and the end cover 4015 is detachably arranged at the opening through bolts to close the shell 4014, and the detachable structure of the end cover 4015 can facilitate the assembly and maintenance of the oil storage container 401.

[0079] In order to filter out impurities in the lubricating oil, in this embodiment, the oil supplementing mechanism 40 further comprises a filter assembly 404, which comprises:

[0080] A plug plate is vertically arranged, and the side surface of the partition plate 4013 is recessed inward in the horizontal direction to form a plug slot suitable for the plug plate. The plug plate is inserted into the plug slot and used to carry the screen cylinder 4041.

[0081] The screen cylinder 4041 is arranged on the plug plate and has a semi-cylindrical structure, is hollow inside, and is closed at both ends. A plurality of hollow holes are formed on the peripheral surface to allow the lubricating oil to flow into the screen cylinder 4041 in the radial direction. More specifically, the screen cylinder 4041 is positioned corresponding to the oil passing hole position on the aforementioned partition plate 4013.

[0082] The rotating drum 4042 is adapted to the screen cylinder 4041. Specifically, the rotating drum 4042 has a semi-cylindrical shape suitable for the screen cylinder 4041 and is slightly smaller in size than the screen cylinder 4041. The rotating drum 4042 is coaxially arranged with the screen cylinder 4041 and rotatably sleeved in the screen cylinder 4041, so that the rotating drum 4042 can rotate around the axial position to adjust the angle of the rotating drum 4042. The peripheral surface of the rotating drum 4042 is formed with a penetrating embedding window.

[0083] The filter bag 4043 is adapted to the embedding window and embedded in the embedding window. Specifically, the two side edges of the embedding window are formed with notches, and the two side edges of the filter bag 4043 are connected with the notches on both sides, respectively, to fix the filter bag 4043 at the embedding window and filter the lubricating oil flowing through the embedding window.

[0084] The second driving member 4044 is connected with the rotating drum 4042 to drive the rotating drum 4042 to rotate. The second driving member 4044 is specifically an electric motor which is coaxially arranged with the rotating drum 4042 and connected through a shaft coupling, so that the second driving member 4044 can drive the rotating drum 4042 to rotate, thereby adjusting the angle of the filter bag 4043, i.e. adjusting the filtering angle of the filter bag 4043 to the lubricating oil, so that the filter bag 4043 always maintains the orientation of the lubricating oil inflow, avoiding the impurities attached to the filter bag 4043 from mixing into the lubricating oil again due to impact.

[0085] During the circulation of the lubricating oil, iron filings may be mixed in from the falling of various parts. In order to effectively remove the iron filings, the inner wall of the oil storage cavity 4011 in the embodiment is further provided with magnetic sheets 4045, which are preferably arranged on the bottom surface of the oil storage cavity 4011 and are two in number and arranged on both sides of the partition plate 4013. The magnetic sheets 4045 can adsorb the iron filings when the lubricating oil flows back into the oil storage container 401. Since the shell 4014 of the power unit 10 can effectively reduce the magnetism of the magnetic sheets inside the motor, the magnetic attraction force received by the iron filings in the circulation pipeline during circulation is smaller, while the magnetic attraction force received by the iron filings in the oil storage container 401 is larger. Therefore, it can be ensured that the iron filings will flow into the oil storage container 401 with the lubricating oil and be adsorbed and removed by the magnetic sheets 4045.

[0086] In order to ensure the flowability of the lubricating oil, and at the same time, in order to improve the heat dissipation performance of the power unit 10 and the reduction unit 20 as much as possible, reduce or avoid the risk of overheating failure of the reduction power system, a heat regulating mechanism 50 is provided in the embodiment, and the heat regulating mechanism 50 specifically comprises:

[0087] The first capsule 501 is annular, arranged on the end face of the power unit towards the reduction unit 20, specifically, the number of the first capsule 501 is two, one of which is arranged on the end face of the power unit, and the other is arranged on the side face of the connecting plate. The first capsule 501 is filled with heat exchange liquid inside, which is used for heat exchange cooling, and the side of the first capsule 501 away from the reduction unit 20 is also formed with a plurality of first heat conductive pieces extending into the inside of the power unit 10. Specifically, the first heat conductive piece is in the shape of a round bar, and a plurality of first heat conductive pieces are distributed around the shaft center of the power unit. The shell 4014 of the power unit is formed with a through hole extending into the inside of the shell 4014 at a position corresponding to each first heat conductive piece, and the plurality of first heat conductive pieces are inserted into the through holes one by one, and the end portions extend into the inside of the power unit 10, so that the first capsule 501 can exchange heat with the inside of the power unit 10 through the first heat conductive pieces;

[0088] The second capsule 502 is arranged on the end face of the reduction unit 20 towards the power unit 10, and the inside of the second capsule 502 is also filled with heat exchange liquid. The second capsule 502 has a second heat conductive piece extending into the inside of the reduction unit 20. The structure of the second heat conductive piece is similar to that of the first heat conductive piece, which can be understood with reference to the structure of the first heat conductive piece, and will not be described here.

[0089] The surfaces of the first capsule 501 and the second capsule 502 are tightly attached to form thermal contact, so that the heat exchange liquid in the first capsule 501 and the second capsule 502 can exchange heat through the first capsule 501 and the second capsule 502. Since the first heat conductive piece and the second heat conductive piece extend into the inside of the power unit 10 and the reduction unit 20 respectively, the power unit 10 and the reduction unit 20 can exchange heat through the structure of the first capsule 501 and the second capsule 502.

[0090] At the same time, since the first capsule 501 and the second capsule 502 are filled with heat exchange liquid, the first capsule 501 and the second capsule 502 have a certain buffering effect, which can effectively buffer the collision at the connection position of the power unit 10 and the reduction unit 20, and reduce the vibration at the connection position.

[0091] The refrigeration piece 503 is specifically a semiconductor refrigeration block, which is arranged on the outer side face of the end cover 4015 and electrically connected to the outside. It can refrigerate when powered on, thereby reducing the temperature of the lubricating oil in the oil storage container 401;

[0093] With the above-mentioned thermal regulation mechanism 50, the lubricating oil can be cooled or warmed up by the refrigeration sheet 503 and the heating sheet 504, on the one hand, the lubricating oil can be heated to maintain a flowing state in a low-temperature environment, on the other hand, the lubricating oil can also take away the heat in the speed reducer set 20 while circulating to lubricate the speed reducer set 20, so as to cool down the speed reducer set 20, when the temperature of the lubricating oil is high, the refrigeration sheet 503 can be used to cool down the lubricating oil to maintain the heat absorption and cooling effect, at the same time, the first bladder 501 and the second bladder 502 can be in thermal contact, so that the power set 10 and the speed reducer set 20 can exchange heat, so that the heat generated by the operation of the power set 10 can be conducted to the speed reducer set 20, and then dissipated by the lubricating oil, thereby achieving the heat dissipation and cooling of the entire speed power system, reducing or avoiding the risk of overheating failure of the speed power system.

[0094] Further, in order to make the first bladder 501 and the second bladder 502 fit stably and ensure that they can stably exchange heat, in the embodiment, a first rubber magnetic sheet 505 is attached to the side of the first bladder 501 facing the second bladder 502, and a second rubber magnetic sheet 506 is attached to the side of the second bladder 502 facing the first bladder 501, the first bladder 501 and the second bladder 502 are adsorbed and fit by the magnetic attraction of the first rubber magnetic sheet 505 and the second rubber magnetic sheet 506, so as to make the first bladder 501 and the second bladder 502 fit stably.

[0095] In order to facilitate the adjustment of the relative position of the power set 10 and the speed reducer set 20, the embodiment also provides a sliding mechanism 60, which specifically includes a guide assembly 601 and a third driving member 602, the guide assembly 601 includes a first guide member 6011 and a second guide member 6012 which are adapted to each other, the first guide member 6011 is arranged on the power set 10 along the axial direction of the power set 10, the second guide member 6012 is arranged on the speed reducer set 20 along the axial direction of the speed reducer set 20 and corresponds to the first guide member 6011, the first guide member 6011 and the second guide member 6012 are slidingly connected, so that the power set 10 and the speed reducer set 20 can approach each other or move away from each other.

[0096] As an optional embodiment, as shown in FIG. 8, Figure 11The first guide 6011 is a long strip-shaped guide sleeve, and the second guide 6012 is a guide rail. The guide sleeve and the guide rail are slidably connected to support and limit the power unit 10, so that the power unit 10 and the speed reducer unit 20 can slide relative to each other. In other alternative embodiments, the first guide 6011 and the second guide 6012 can also use common guide structures such as guide sleeves and guide rails, sliding rails and sliding blocks.

[0097] The third driving member 602 is connected with the power unit 10 and / or the speed reducer unit 20 to provide power to drive the power unit 10 and / or the speed reducer unit 20 to slide along the guide assembly 601. For example, the third driving member 602 is an electric motor, and there are four electric motors arranged at the four corners of the power unit 10 housing. The motor shaft is coaxial with the power unit 10. The four corners of the power unit 10 housing are provided with sliding grooves for mounting the electric motor. The motor side is fixed with a sliding block which is slidably arranged in the sliding groove.

[0098] The power unit 10 and the speed reducer unit 20 are connected by four screws, which are in one-to-one correspondence with the four electric motors. One end of the screw is threadedly connected with the speed reducer unit 20, and the other end is connected with the output shaft of the electric motor. When the electric motor rotates, it can drive the screw to rotate, and through the cooperation of the sliding block and the sliding groove and the guiding effect of the above-mentioned guide assembly 601, the power unit 10 and the speed reducer unit 20 can slide relative to each other.

[0099] In other alternative embodiments, the third driving member 602 can also use common linear motion modules such as electric telescopic rods, hydraulic telescopic rods or telescopic cylinders.

[0100] The power connection mechanism 30 includes a first connecting end 301 and a second connecting end 302. The first connecting end 301 is coaxially connected with the first output shaft, and the second connecting end 302 is coaxially connected with the power input end of the speed reducer unit 20.

[0101] The end surface of the first connecting end 301 facing the second connecting end 302 is formed with a plurality of clamping grooves, and the end surface of the second connecting end 302 facing the first connecting end 301 is formed with a plurality of clamping blocks. The clamping blocks and the clamping grooves are in one-to-one correspondence and are matched with each other. The clamping blocks and the clamping grooves are inserted and connected. More specifically, the side surface of the clamping block is arc-shaped to facilitate quick positioning with the clamping groove. The structure of the clamping block and the clamping groove can quickly insert and connect the first connecting end 301 and the second connecting end 302, and can limit the relative rotation of the first connecting end 301 and the second connecting end 302.

[0102] As another possible embodiment, the clamping blocks can also be arranged on the end surface of the first connecting end 301, and the clamping grooves can be arranged on the end surface of the second connecting end 302. The specific insertion structure can be understood with reference to the description above, and will not be described here.

[0103] Further, in the embodiment, the circulation oil path 402 specifically comprises a first pipe 4021 and a second pipe 4022 arranged on the two sides respectively, the upper and lower ends of the side edge of the speed reducer set 20 are respectively formed with a first connecting hole and a second connecting hole communicated with the inside of the speed reducer set 20, the third connecting hole and the fourth connecting hole communicated with the oil storage cavity 4011 are respectively formed on the side edges of the oil storage container 401 in the width direction, one end of the first pipe 4021 is connected with the second connecting hole, and the other end is connected with the third connecting hole, the first pipe 4021 can be divided into a soft pipe section in the front section and a hard pipe section in the rear end, the soft pipe section is made of soft material and can be stretched and moved, and the hard pipe section is in a multi-section S shape, the second pipe 4022 has a structure similar to that of the first pipe 4021, and through the above circulation pipe, the lubricating oil can be circulated and flowed between the oil storage container 401 and the speed reducer set 20.

[0104] The oil injection hole is further arranged at the side edge of the oil storage container 401, and an oil injection pipe 4016 is connected to the oil injection hole for supplementing the lubricating oil. The oil injection pipe 4016 is usually screwed with a sealing cover.

[0105] In order to avoid the entry of external air into the oil storage cavity 4011, a one-way air valve is arranged in the exhaust hole 4012 in the embodiment, and the one-way air valve is arranged to have a one-way flowability of gas flowing outward.

[0106] The working process of the speed reduction power system of the embodiment will be described in detail below in combination with the above content:

[0107] Before the speed reduction power system is used, an appropriate amount of lubricating oil can be added to the oil storage container 401 through the oil injection pipe 4016 in advance, and then the oil injection pipe 4016 is sealed.

[0108] The first driving member 4032 at the top of the oil storage container 401 is started to drive the pressing plate 4031 to move slowly downward, and in the process of moving downward, the pressing plate 4031 is tightly fitted with the inner wall of the oil storage cavity 4011 around the pressing plate 4031 to effectively extrude the lubricating oil, and through the structure of the arc-shaped groove, the air in the lubricating oil is collected to the filter hole position at the bottom of the arc-shaped groove, filtered through the air filter membrane 4033, and finally discharged outward from the exhaust hole 4012 through the one-way air valve.

[0109] During the pressing process of the pressing plate 4031, the second driving member 4044 drives the rotating drum 4042 to rotate, and cooperates with the normal operation of the speed reducer set 20. During the rotation of the star-shaped arm 205, the rotating drum 4042 forms a structure similar to a circulating pump, so that the lubricating oil circulates in the circulating oil path 402 between the speed reducer set 20 and the oil storage container 401, lubricates the parts in the speed reducer set 20, and continuously removes the air in the speed reducer set 20. After the air enters the oil storage container 401 with the lubricating oil, it is extruded and discharged through the pressing process of the pressing plate 4031 described above.

[0110] During the above process, the pressure sensor at the lower part of the pressing plate 4031 detects the pressure inside the oil storage cavity 4011 in real time. When the pressure reaches a preset threshold, the first driving member 4032 and the second driving member 4044 stop running, the lubricating oil is effectively filled into the speed reducer set 20, and a large amount of air in it is discharged, so that the speed reducer set 20 can operate in good operating conditions.

[0111] During the operation, the lubricating oil will be consumed, resulting in a decrease in internal pressure. When the pressure is detected to decrease to a certain value, the first driving member 4032 and the second driving member 4044 are controlled to run, to supplement the lubricating oil into the speed reducer set 20 and discharge the air.

[0112] During the circulation of the lubricating oil, the second driving member 4044 can control the rotation angle of the rotating drum 4042, so that the filter bag 4043 is kept in the direction of the flow of the lubricating oil, so that the filter bag 4043 can effectively filter the fine impurities in the lubricating oil, and the fine impurities attached will not be impacted and mixed into the lubricating oil again due to the change of the flow direction of the lubricating oil.

[0113] Meanwhile, the magnetic attraction piece 4045 at the bottom of the oil storage cavity 4011 can also remove the iron filings in the lubricating oil.

[0114] On the other hand, during the continuous operation of the speed reduction power system, the internal temperature of the power set 10 and the speed reducer set 20 will gradually increase. Since the lubricating oil circulates between the speed reducer set 20 and the oil storage container 401, it can cool the inside of the speed reducer set 20, and when the lubricating oil flows through the circulating oil path 402 arranged outside the power set 10, it can also produce a certain heat exchange cooling effect on the power set 10. More importantly, through the heat exchange structure of the first capsule 501 and the second capsule 502, the power set 10 can transfer the internal heat to the speed reducer set 20, and then cool the speed reducer set 20 through the heat exchange of the lubricating oil, to achieve the heat dissipation and cooling of the power set 10 and the speed reducer set 20.

[0115] When the temperature of the lubricating oil is high and cannot effectively reduce the temperature, the refrigeration sheet 503 can be used to reduce the temperature of the lubricating oil, and when the temperature of the lubricating oil rises to cause volume expansion, the pressure in the oil storage cavity 4011 rises, at this time, the first driving part 4032 drives the pressing plate 4031 to move upwards, providing space for the expanded lubricating oil, reducing the risk of lubricating oil leakage, and during the upward movement, the air in the upper part can be squeezed out of the exhaust hole 4012.

[0116] In addition, the heating sheet 504 is arranged, when the ambient temperature is low and the lubricating oil condenses, the heating sheet 504 can be used to heat the lubricating oil to a suitable temperature range to ensure its fluidity.

[0117] In addition, during the operation of the deceleration power system, when the external equipment connected to the speed reducer set 20 is stuck, if the staff does not stop in time, and the relay also fails, the bearing of the power set 10 will be stuck, which will cause the coil current to rise rapidly, and then the coil temperature will rise, and finally the power set 10 will be burned out.

[0118] At this time, the third driving part 602 can drive the power set 10 to slide away from the speed reducer set 20, so that the first connecting end 301 and the second connecting end 302 are separated, thereby realizing power disengagement, which can effectively protect the power set 10 and avoid burning out of the power set 10. During routine maintenance, the third driving part 602 can also be used to separate the power set 10 from the speed reducer set 20, which is convenient for maintenance.

[0119] The present disclosure can reduce the risk of lubricating oil leakage by arranging the pressing plate 4031 in the oil storage container 401, which can squeeze out the air mixed in the lubricating oil, reduce the pitting damage to the parts caused by the mixed air, effectively protect the speed reducer set 20, improve the stability and service life of the speed reducer set 20, and reduce the risk of lubricating oil leakage;

[0120] The present disclosure sets the thermal regulation mechanism 50, which can regulate the temperature of the lubricating oil through the refrigeration sheet 503 and the heating sheet 504, and can realize heat exchange between the speed reducer set 20 and the power set 10 through the first capsule 501 and the second capsule 502, so that the lubricating oil, the speed reducer set 20 and the power set 10 can be thermally regulated according to the operating conditions, which can ensure smooth circulation of the lubricating oil, stable and effective lubrication and heat exchange, improve the heat dissipation performance of the speed reducer set 20 and the power set 10, achieve better cooling effect, reduce the risk of overheating damage of the equipment, and improve the service life of the speed reducer set 20 and the power set 10;

[0121] The disclosure sets the filtering assembly 404, and sets the magnetic attraction piece 4045 on the inner wall of the oil storage container 401. The filtering assembly 404 can effectively filter out the internal impurities of the lubricating oil. The magnetic attraction piece 4045 can effectively adsorb the iron filings impurities in the lubricating oil, can reduce or remove various impurities in the lubricating oil, reduce or avoid the risk of impurities damaging the components of the speed reducer set 20, and improve the stability and service life of the speed reducer set 20; and the filtering assembly 404 adjusts the orientation of the filtering bag 4043 through the rotatable rotating drum 4042, so that the filtering bag 4043 keeps the orientation of the lubricating oil inflow, so that the impurities attached to the filtering bag 4043 will not be mixed into the lubricating oil again due to impact, and the lubricating oil can be circulated to start the continuous and effective lubrication effect, and the amount of impurities in the lubricating oil will not increase gradually during the flow process, effectively ensuring the continuous and stable operation of the speed reducer set 20.

[0122] The disclosure sets the sliding mechanism 60 between the power unit 10 and the speed reducer set 20. The sliding mechanism 60 includes a guide assembly 601 and a third driving member 602, so that the power unit 10 can be driven by the third driving member 602 to approach or move away from each other, so that the power unit 10 and the speed reducer set 20 are connected stably and the power transmission is stable in normal working state. In the fault state, the power unit 10 and the speed reducer set 20 can be quickly separated, which plays a role in protecting the power unit 10, and in normal maintenance, the separated state is also more convenient for maintenance of the internal unit.

[0123] In the description of the present disclosure, it should be understood that the orientation words such as "front, rear, upper, lower, left, right", "transverse, vertical, horizontal" and "top, bottom" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present disclosure and simplifying the description. Without making the opposite statement, these orientation words do not indicate and imply that the devices or elements indicated must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present disclosure.

[0124] For those skilled in the art, other various corresponding changes and deformations can be made according to the above described technical solutions and concepts, and all these changes and deformations should belong to the protection scope of the claims of the present disclosure.
