Description

Technical Field

[0001] The present invention relates to the technical field of planetary roller screws, and in particular to a planetary rolling thread transmission device and method. Background Art

[0002] The planetary rolling thread transmission device is a high-rigidity, high-load transmission mechanism that mainly transmits motion and power through the multi-point spiral surface engagement between multiple planetary rollers, the screw and the nut. It uses the rotation of the screw and the circumference of the nut to make the rollers perform planetary-like motion in the circumferential direction. At the same time, the spiral transmission converts the rotational motion of the screw (or nut) into linear reciprocating motion of the nut (or screw). It has the advantages of high efficiency and large load-bearing capacity and is widely used in the industrial field.

[0003] However, due to the threaded connection movement of multiple threaded rods in the existing planetary rolling thread transmission device, a large friction force is generated between the screw rod and the transmission structure inside the nut, which in turn accelerates the wear and aging rate of the screw rod, thereby affecting the service life of the planetary rolling thread transmission device. If the wear is large, it will also affect its performance.

[0012] Furthermore, it also includes a heating component, which includes a first fixed seat, which is fixedly installed on one side of the bottom of the piston plate and has a third pin shaft arranged inside.

[0013] Furthermore, there are multiple heating rods, a connecting piece is provided between every two adjacent heating rods, and the third fixing seat is provided on the top of one of the heating rods.

[0014] Furthermore, a positioning piece is fixedly installed on one side of the liquid storage tank, and the positioning piece is against the outer surface of the first nut pair. A plurality of bolts are inserted into the top thread of the positioning piece, and the ends of the bolts extend into the first nut pair.

[0015] The present invention also discloses a planetary rolling thread transmission method, which uses the planetary rolling thread transmission device and includes the following steps:

[0016] S1: During use, when the threaded screw rotates, the threaded rod drives the turntable to rotate as it is threadedly connected to the threaded screw, and since the planetary gear is meshing with the teeth of the inner ring of the inner gear, the planetary gear also drives the threaded rod to rotate, so that the inner ring and the first nut pair move along the direction set by the threaded screw. However, due to the large number of threaded rods, the friction between the threaded rods and the threaded screw is too large. In order to avoid large wear of the threaded screw, the nozzle is turned on at this time, so that the lubricating oil in the liquid storage tank can be dropped onto the threaded screw through the nozzle to lubricate it, which can effectively reduce friction loss, thereby helping to extend the service life of the planetary rolling thread transmission device.

[0017] S2: In S1, since the turntable rotates and its speed is the same as that of the threaded screw, the turntable will drive the blades to move, generating wind force to push the slide plate to compress the spring and slide inward in the fixed groove. When the contact block hits the electromagnetic button, it means that the speed of the blade is high. Then the electromagnetic button sends an electrical signal to the motor to activate it. Then the drive shaft of the motor drives the bidirectional screw to rotate. During this process, the two second nut pairs will approach each other and the rotating part will push the piston plate downward, which can actively squeeze the lubricating liquid in the liquid storage tank, so that the lubricating liquid is accelerated to spray on the threaded screw, avoiding the problem of insufficient lubrication due to the excessive speed of the threaded rod, and further reducing the wear on the threaded screw.

[0018] S3: In S1 and S2, if the planetary rolling thread transmission device is used in severe cold low-end, the temperature of the lubricating oil in the liquid storage tank is low at this time, which will cause the viscosity of the lubricating oil to increase and the fluidity to weaken, thus affecting its lubrication effect. At this time, the micro electric push rod can be turned on before turning on the motor, so that the driving end of the micro electric push rod is extended to drive the heating rod to slowly rotate downward with the first fixed seat as the axis. At the same time, the electric heating wire is turned on to make the electric heating wire heat up and diffuse the heat outward, so as to preheat the lubricating oil in the liquid storage tank, so that the viscosity of the lubricating oil will be reduced and the fluidity will be enhanced, thereby further reducing the wear on the threaded screw. It should be noted that we can unplug the cap and then add new lubricating oil to the liquid storage tank through the filling tube to ensure that there is enough lubricating oil.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. By opening the nozzle, the lubricating oil in the liquid storage tank can be dropped onto the threaded screw through the nozzle to lubricate it, which can effectively reduce friction loss and thus help to extend the service life of the planetary rolling thread transmission device.

[0020] 2. The rotation of the turntable will drive the blades to move, which can generate wind force to push the slide plate to compress the spring and make the contact block counteract the electromagnetic button. At this time, it means that the speed of the blades is relatively high. Then the electromagnetic button turns on the motor, and then the drive shaft of the motor drives the bidirectional screw to rotate. During this process, the two second nut pairs will approach each other and make the rotating part push the piston plate downward, which can actively squeeze the lubricating liquid in the liquid storage tank, so that the lubricating liquid is accelerated to spray on the threaded screw, avoiding the problem of insufficient lubrication due to the excessive speed of the threaded rod, and can further reduce the wear on the threaded screw.

[0021] 3. By turning on the micro electric push rod, the driving end of the micro electric push rod can be extended to drive the heating rod to slowly rotate downward with the first fixed seat as the axis. At the same time, the electric heating wire is turned on to heat the electric heating wire and diffuse the heat outward, so that the lubricating oil in the liquid storage tank can be preheated, so that the viscosity of the lubricating oil will be reduced and the fluidity will be enhanced, thereby further reducing the wear on the threaded screw.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figure 1-6 The present invention provides a technical solution: a planetary rolling thread transmission device, including a threaded screw 1, a transmission assembly is provided on the threaded screw 1, the transmission assembly includes a first nut pair 2, the first nut pair 2 is sleeved on the threaded screw 1, and the inner ring of the first nut pair 2 is fixedly installed with two internal gear rings 3, a turntable 4 is rotatably provided in the inner gear ring 3, and a plurality of planetary gears 5 are rotatably plugged into one side of the turntable 4, and the planetary gear 5 is meshed with the teeth of the inner ring of the inner gear ring 3. One end of the planetary gear 5 is integrally formed with a threaded rod 6, which is threadedly connected to the threaded screw 1. A liquid storage tank 8 is fixedly installed on the top of the first nut pair 2, and lubricating oil is provided in the liquid storage tank 8. A nozzle 9 is provided at the bottom of the liquid storage tank 8, and a liquid injection pipe 32 is fixedly installed on one side of the liquid storage tank 8. A cap is movably sleeved on the liquid injection pipe 32, and sealing members 7 for limiting the turntable 4 are provided on both sides of the first nut pair 2.

[0032] During specific implementation, when the threaded screw 1 rotates, since the threaded rod 6 is threadedly connected to the threaded screw 1, the threaded rod 6 will drive the turntable 4 to rotate, and since the planetary gear 5 is meshing with the teeth of the inner ring of the inner gear 3, the planetary gear 5 will also drive the threaded rod 6 to rotate, so that the inner ring 3 and the first nut pair 2 move along the direction set by the threaded screw 1. Due to the large number of threaded rods 6, the friction between the threaded rod 6 and the threaded screw 1 is too large. In order to avoid large wear of the threaded screw 1, the nozzle 9 is turned on at this time, and the lubricating oil in the liquid storage tank 8 can be dropped onto the threaded screw 1 through the nozzle 9 to lubricate it, which can effectively reduce friction loss, thereby helping to extend the service life of the planetary rolling thread transmission device.

[0033] See Figure 1-6 As shown, it also includes a speed regulating assembly, which includes a piston plate 10, which is slidably connected to the liquid reservoir 8, and a bidirectional screw rod 11 is rotatably provided in the liquid reservoir 8. Two second nut pairs 12 are threadedly sleeved on the bidirectional screw rod 11, and a distance is left between the second nut pair 12 and the piston plate 10 and they are transmission connected. A motor 13 is fixedly installed on one side of the liquid reservoir 8, and the driving shaft of the motor 13 is transmission-connected to one end of the bidirectional screw rod 11. A guide rod 14 is inserted in the second nut pair 12, and both ends of the guide rod 14 are fixedly installed in the liquid reservoir 8. A detection assembly is also provided on the first nut pair 2, and the detection assembly is electrically connected to the motor 13. A first mounting seat 15 is fixedly installed on the bottom of the second nut pair 12, and a rotating member 16 is rotatably provided in the first mounting seat 15. A second mounting seat 17 is fixedly installed on the top of the piston plate 10, and the other end of the rotating member 16 is rotatably provided in the second mounting seat 17;

[0034] A first pin is provided in the first mounting seat 15, a second pin is provided in the second mounting seat 17, and both ends of the rotating member 16 are rotatably sleeved on the first pin and the second pin respectively. The detection assembly includes a detection member 18, which is fixedly mounted on one side of the first nut pair 2 and has a fixing groove 24 on one side thereof. A slide plate 19 is slidingly provided in the fixing groove 24, and two springs 20 are provided between the slide plate 19 and the side wall of the fixing groove 24. A contact block 21 is fixedly installed on one side of the slide plate 19, and an electromagnetic button 22 is provided on the inner side wall of the fixing groove 24. The electromagnetic button 22 cooperates with the contact block 21 to abut against each other, and the electromagnetic button 22 is electrically connected to the motor 13. A plurality of blades 23 are fixedly mounted on one side of the turntable 4, and a distance is left between the blades 23 and the detection member 18.

[0035] During specific implementation, based on the above implementation, since the turntable 4 will rotate, and the speed of the turntable 4 is the same as that of the threaded screw 1, the turntable 4 will drive the blade 23 to move, which can generate wind force to push the slide plate 19 to compress the spring 20 and slide inward in the fixed groove 24. When the contact block 21 is against the electromagnetic button 22, it means that the speed of the blade 23 is relatively high. Then the electromagnetic button 22 sends an electrical signal to the motor 13 and activates it. Then the drive shaft of the motor 13 drives the bidirectional screw 11 to rotate. During this process, the two second nut pairs 12 will approach each other and cause the rotating part 16 to push the piston plate 10 downward, which can actively squeeze the lubricating liquid in the liquid storage tank 8, so that the lubricating liquid is accelerated to spray on the threaded screw 1, avoiding the problem of insufficient lubrication due to the excessive speed of the threaded rod 6, and can further reduce the wear on the threaded screw 1.

[0036] See Figure 1-6 , also includes a heating component, the heating component includes a first fixed seat 25, the first fixed seat 25 is fixedly mounted on one side of the bottom of the piston plate 10 and a third pin is provided inside, a heating rod 26 is rotatably sleeved on the third pin, and an electric heating wire 27 is wound around the heating rod 26, a second fixed seat 28 is fixedly mounted on the other side of the bottom of the piston plate 10, a fourth pin is provided in the second fixed seat 28, a micro electric push rod 29 is rotatably sleeved on the fourth pin, a third fixed seat 30 is provided on the top of the heating rod 26, a fifth pin is provided in the third fixed seat 30, the driving end of the micro electric push rod 29 is rotatably sleeved on the fifth pin, the number of heating rods 26 is multiple, a connecting member 31 is provided between every two adjacent heating rods 26, and the third fixed seat 30 is provided on the top of one of the heating rods 26.

[0037] During specific implementation, based on the above implementation, if the planetary rolling thread transmission device is used in severe cold low-end, the temperature of the lubricating oil in the liquid storage tank 8 is low at this time, which will cause the viscosity of the lubricating oil to increase and the fluidity to weaken, thereby affecting its lubrication effect. At this time, the micro electric push rod 29 can be turned on first before turning on the motor 13, so that the driving end of the micro electric push rod 29 is extended to drive the heating rod 26 to rotate slowly downward with the first fixed seat 25 as the axis. At the same time, the electric heating wire 27 is turned on to make the electric heating wire 27 heat up and diffuse the heat outward, so as to preheat the lubricating oil in the liquid storage tank 8, so that the viscosity of the lubricating oil will be reduced and the fluidity will be enhanced, thereby further reducing the wear on the threaded screw 1. It should be noted that we can unplug the cap and then add new lubricating oil to the liquid storage tank 8 through the injection pipe 32 to ensure that there is enough lubricating oil.

[0038] See Figure 1-6A positioning member 33 is fixedly installed on one side of the liquid storage tank 8, and the positioning member 33 abuts against the outer surface of the first nut pair 2. A plurality of bolts 34 are threadedly inserted into the top of the positioning member 33, and the ends of the bolts 34 extend into the first nut pair 2. The detachable liquid storage tank 8 can be easily disassembled and maintained.

[0039] It should be noted that the electrical appliances involved in the planetary rolling screw transmission device can be equipped with batteries (not shown in the figure) installed on the rear side of the liquid storage tank 8, so that the batteries are electrically connected to the electrical appliances to provide them with electrical energy, ensuring their normal operation. Since the batteries and the installation of batteries are both existing well-known technologies, they will not be explained in detail in this manual.

[0040] In combination with the above-mentioned planetary rolling thread transmission device, a method for planetary rolling thread transmission is provided below, which specifically includes the following steps:

[0041] S1: During use, when the threaded screw 1 rotates, since the threaded rod 6 is threadedly connected to the threaded screw 1, the threaded rod 6 will drive the turntable 4 to rotate accordingly, and since the planetary gear 5 is meshing with the teeth of the inner ring of the inner gear 3, the planetary gear 5 will also drive the threaded rod 6 to rotate, so that the inner ring 3 and the first nut pair 2 move along the direction set by the threaded screw 1. However, since there are a large number of threaded rods 6, the friction between the threaded rod 6 and the threaded screw 1 is too large. In order to avoid large wear of the threaded screw 1, the nozzle 9 is turned on at this time, so that the lubricating oil in the liquid storage tank 8 can be dropped onto the threaded screw 1 through the nozzle 9 to lubricate it, which can effectively reduce friction loss, thereby helping to extend the service life of the planetary rolling thread transmission device;

[0042] S2: In S1, since the turntable 4 rotates, and the rotation speed of the turntable 4 is the same as that of the threaded screw 1, the turntable 4 will drive the blade 23 to move, which can generate wind force to push the slide plate 19 to compress the spring 20 and slide inward in the fixed groove 24. When the contact block 21 is against the electromagnetic button 22, it means that the rotation speed of the blade 23 is relatively high. Then the electromagnetic button 22 sends an electrical signal to the motor 13 and activates it. Then the drive shaft of the motor 13 drives the bidirectional screw 11 to rotate. During this process, the two second nut pairs 12 will approach each other and cause the rotating part 16 to push the piston plate 10 downward, which can actively squeeze the lubricating liquid in the liquid storage tank 8, so that the lubricating liquid is accelerated to spray on the threaded screw 1, avoiding the problem of insufficient lubrication due to the excessive rotation speed of the threaded rod 6, and further reducing the wear on the threaded screw 1;

[0043] S3: In S1 and S2, if the planetary rolling thread transmission device is used in severe cold low-end, the temperature of the lubricating oil in the liquid storage tank 8 is low at this time, which will cause the viscosity of the lubricating oil to increase and the fluidity to weaken, thereby affecting its lubrication effect. At this time, the micro electric push rod 29 can be turned on first before turning on the motor 13, so that the driving end of the micro electric push rod 29 is extended to drive the heating rod 26 to rotate slowly downward with the first fixed seat 25 as the axis. At the same time, the electric heating wire 27 is turned on to make the electric heating wire 27 heat up and diffuse the heat outward, so as to preheat the lubricating oil in the liquid storage tank 8, so that the viscosity of the lubricating oil will be reduced and the fluidity will be enhanced, thereby further reducing the wear on the threaded screw 1. It should be noted that we can unplug the cap and then add new lubricating oil to the liquid storage tank 8 through the injection pipe 32 to ensure that there is enough lubricating oil.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

Then the electromagnetic button (22) sends an electrical signal to the motor (13) and activates it. Then the drive shaft of the motor (13) drives the bidirectional screw (11) to rotate. During this process, the two second nut pairs (12) will approach each other and make the rotating member (16) push the piston plate (10) to move downward, which can actively squeeze the lubricating liquid in the liquid storage tank (8) so that the lubricating liquid is accelerated to spray on the threaded screw (1), avoiding the problem of insufficient lubrication due to the excessive rotation speed of the threaded rod (6), and further reducing the wear on the threaded screw (1); S3: In S1 and S2, if the planetary rolling thread transmission device is used in a cold and low-end environment, the temperature of the lubricating oil in the liquid storage tank (8) is low, which will cause the viscosity of the lubricating oil to increase and the fluidity to decrease, thereby affecting its lubrication effect. At this time, before turning on the motor (13), the micro electric push rod (29) can be turned on first, so that the driving end of the micro electric push rod (29) is extended to drive the heating rod (26) to rotate slowly downward with the first fixed seat (25) as the axis. At the same time, the electric heating wire (27) is turned on to heat the electric heating wire (27) and diffuse the heat outward, so that the lubricating oil in the liquid storage tank (8) can be preheated, so that the viscosity of the lubricating oil will decrease and the fluidity will increase, thereby further reducing the wear on the threaded screw (1). It should be noted that we can remove the cap and then add new lubricating oil to the liquid storage tank (8) through the injection pipe (32) to ensure that there is enough lubricating oil.
