Description

TECHNICAL FIELD

[0001] The application belongs to the technical field related to transmission devices, and specifically discloses a planetary gear transmission device. BACKGROUND

[0002] The worm planetary gear transmission is a composite transmission form combining the structural characteristics of worm transmission and planetary gear transmission, and has the advantages of both, and is suitable for transmission requirements of specific scenes.

[0003] From the structural composition, it takes the worm as the central transmission part, replaces the sun gear in the traditional planetary gear transmission, and uniformly distributes a plurality of planetary gears (symmetrically arranged along the worm circumference) around the worm. These planetary gears are simultaneously meshed with the spiral tooth surface of the worm and the inner ring gear on the outside, and the planetary gears are installed on the planet carrier through bearings, forming a multi-tooth meshing system of "worm-planet gear-inner ring gear". This structure not only retains the advantages of worm transmission "large transmission ratio (single-stage transmission ratio can reach 10-60), smooth running", but also realizes power splitting by means of revolution and rotation of the planetary gears. After the power is input from the worm, it is dispersed to each planetary gear, and then output through the planet carrier or the inner ring gear, so it can bear a larger load like planetary gear transmission.

[0004] Based on these characteristics, the worm planetary gear transmission is often used in scenes that require large transmission ratio, small installation space, and certain bearing capacity, such as precision reducers, servo transmission systems, and rotary mechanisms of engineering machinery. The core of its structural design is to balance the meshing coordination of the worm and the planetary gear and optimize the lubrication efficiency to alleviate the wear problem.

[0005] The worm transmission planetary gear may have the following problems in the working process:

[0006] In the worm transmission, due to the irregular shape of the tooth surface after wear, especially in the worm spiral groove root and tooth top where wear is serious, it is necessary to add lubricating grease. Manual regular greasing and inspection not only consumes a lot of manpower, material resources and time, but also is difficult to ensure the accuracy and comprehensiveness of the operation. When manually brushing lubricating grease on the worm transmission, since the worm is usually installed in the transmission box which is not easy to disassemble, the lower side and some hidden meshing area positions are difficult to reach, so these areas cannot be effectively lubricated in time.

[0007] In addition, the temperature change of the lubricating grease can directly reflect the friction working condition of the worm and planetary gear transmission device. In the normal working state, the temperature of the lubricating grease is generally stable in the range of 50-65 DEG C, indicating that the friction of the transmission device is at a reasonable level and the operation is relatively stable. However, when the friction is intensified due to wear, poor lubrication or other reasons, the temperature of the lubricating grease will rapidly increase and can easily exceed 80 DEG C. However, in the prior art, the lubricating grease temperature monitoring and the lubricating action are often independent of each other, and an effective correlation mechanism cannot be established. When the temperature monitoring system detects an abnormal increase in temperature, it cannot timely and automatically strengthen the lubrication by adjusting the lubricating amount and the lubricating frequency or the like to inhibit the intensifying wear.

[0008] Therefore, a planetary gear transmission device is provided to solve the above problems. SUMMARY

[0010] In the above technical solution, the folding mechanism further comprises a hydraulic telescopic rod fixedly clamped on one end of the inner portion of the side shell, the telescopic end of the hydraulic telescopic rod being fixedly connected with a clamping block, the clamping block being fixedly sleeved on the outer portion of the hard pipe, and the clamping block being slidably attached to the inner wall of the sliding groove on both sides.

[0011] In the above technical solution, the oil injection mechanism further comprises a volumetric lubricating pump, a connector pipe being fixedly installed on the inner portion of the upper portion of the volumetric lubricating pump, the volumetric lubricating pump being fixedly installed on the upper surface of one side of the shell, a telescopic hose being fixedly installed on the inner portion of the lower portion of the volumetric lubricating pump, the telescopic hose being connected with the hard pipe, and heat dissipation grids being respectively installed on the outer portions of the shell on both sides and close to the upper portion.

[0012] In the technical scheme, further, the brush oil mechanism comprises a clamping shell clamped outside the fixed block, a frame fixedly installed on the side of the clamping shell away from the fixed block, a first U-shaped frame fixedly installed outside one end of the frame and vertically arranged, and nylon brushes equidistantly installed on the outer surface of the first U-shaped frame in the vertical direction.

[0013] In the technical scheme, further, a high-pressure air pump is fixedly clamped at the rear end of the frame, a vertical pipe is fixedly installed at one end of the high-pressure air pump, the vertical pipe is vertically inserted into the first U-shaped frame, and a shunt mechanism is arranged in the vertical pipe.

[0014] In the technical scheme, further, the shunt mechanism comprises atomizing nozzles equidistantly and communicatively installed in the vertical pipe in the vertical direction, electromagnetic induction heating devices fixedly sleeved outside the atomizing nozzles, the atomizing nozzles penetrating through the outside of the first U-shaped frame, and the atomizing nozzles being correspondingly arranged between the two groups of nylon brushes close to each other.

[0015] In the technical scheme, further, a second U-shaped frame is fixedly arranged outside the side of the frame away from the clamping shell in the transverse direction, a probe is fixedly clamped in the second U-shaped frame, a temperature sensing buzzer is electrically connected to the rear end of the probe, and the temperature sensing buzzer is fixedly installed on the outer wall of the second U-shaped frame.

[0016] In the technical scheme, further, two groups of symmetrical mounting holes are formed in the upper surface of the clamping shell, mounting screws are threadedly connected in the mounting holes, and the bottom ends of the mounting screws extend into the fixed block.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. The volume lubricating pump, the hard pipe movable along the length direction of the worm shaft and the brush oil mechanism are combined, so that the automatic delivery of lubricating grease and the uniform brushing of the worm surface can be realized. The volume lubricating pump can accurately control the output of lubricating grease, avoiding the problems of uneven amount or omission during traditional manual grease supplementing. Meanwhile, the hard pipe is reciprocally moved along the sliding groove by the folding back mechanism, so that the brush oil mechanism can cover the root of the spiral groove of the worm, the tooth top and other areas prone to wear and difficult to reach by manual operation, effectively solving the lubrication blind area problem of irregular wear parts of the worm and reducing the risk of gap expansion caused by insufficient lubrication.

[0019] 2. By incorporating a synergistic structure of a nylon brush and an atomizing nozzle in the oiling mechanism, the lubrication effect and nozzle anti-clogging capability can be further improved. As the nylon brush moves with the rigid tube, it evenly applies grease to the worm gear surface, ensuring full coverage of the meshing surfaces. Simultaneously, the atomizing nozzle blows back the grease adhering to the outside of the nylon brush to the outer surface of the worm gear shaft, thus ensuring continuous coating effect. An electromagnetic induction heating device is installed outside the atomizing nozzle to heat the grease, reducing its viscosity and preventing nozzle clogging caused by high grease viscosity.

[0020] 3. By installing a temperature probe and a temperature-sensing buzzer next to the oiling mechanism, the temperature changes of the worm gear surface and the lubricating grease can be monitored in real time. When the temperature rises abnormally, it can be promptly determined that the worm gear friction has intensified. At this time, no manual intervention is required; the positive displacement lubrication pump can automatically adjust the lubricating grease output, which, together with the reciprocating brushing action of the oiling mechanism, can enhance lubrication and inhibit further friction. The temperature-sensing buzzer will sound an alarm when the temperature exceeds the limit, reminding the staff to check for wear or lubrication abnormalities, avoiding a vicious cycle caused by wear leading to an increase in the clearance between the worm gear shaft and the planetary gear module, resulting in more severe wear, and extending the service life of the worm gear and planetary gear module.

[0021] 4. By designing the oiling mechanism with a detachable clamp and fixing block connection structure, subsequent maintenance and component replacement are convenient. When the nylon brush shows wear or the atomizing nozzle needs cleaning, simply remove the mounting screws on the clamp to detach the oiling mechanism from the rigid tube, without disassembling the entire transmission device, significantly reducing maintenance difficulty and time. Simultaneously, the external heat dissipation grille helps reduce the internal operating temperature, minimizing the impact of high temperatures on the lubricant's performance, further ensuring the stability of the lubrication effect, and maintaining the accuracy and smoothness of the worm gear planetary gear transmission.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-6 The planetary gear transmission device shown includes a base 1, a worm shaft 7, a planetary gear module 8, and a transmission shaft 31. A motor 2 is fixedly mounted on the upper surface of one side of the base 1, and a housing 3 is fixedly mounted on the upper surface of the base 1 away from the motor 2. A fixing seat 32 is fixedly provided at one end of the bottom inner side of the housing 3. The planetary gear module 8 is installed through the rear end of the transmission shaft 31, and one end of the transmission shaft 31 passes through the fixing seat 32 and the outside of the housing 3. The worm shaft 7 is rotatably disposed inside the housing 3 and its end is fixedly connected to the output shaft of the motor 2. The worm shaft 7 is located inside the housing 3 and is located within the housing 3. A ring frame 17 is fitted on the top of the worm shaft 7. The upper end of the ring frame 17 is connected to the inside of the housing 3 by a fixed fastener 10. A C-shaped ring shell 11 is fixedly installed on the outer surface of the ring frame 17. The C-shaped ring shell 11 is fitted on the outside of the worm shaft 7. A side shell 9 is installed inside the C-shaped ring shell 11. A groove 16 is opened on the upper surface of one side of the side shell 9. A rigid tube 13 is connected inside the groove 16 by a set folding mechanism. An oil injection mechanism is set at the upper end of the rigid tube 13. Fixing blocks 25 are symmetrically installed on both sides of the lower part of the rigid tube 13. An oil brushing mechanism is set on the outside of each fixing block 25.

[0032] The output shaft of motor 2 is directly fixedly connected to the end of worm shaft 7, and after starting, it can drive worm shaft 7 to rotate stably inside housing 3;

[0033] The planetary gear module 8 is composed of planetary gears, a planet carrier, an inner ring gear and the like, and can position the transmission shaft 31 under the connection of the fixed seat 32 to prevent the transmission shaft 31 from deviating during operation;

[0034] The ring holder 17 installs the C-shaped ring shell 11 outside the worm shaft 7 through the fixing member 10 composed of a fixing screw and a fixing plate connected with the C-shaped ring shell 11, and the fixing plate can be stably installed to the inner wall of the shell 3 through the fixing screw;

[0035] The sliding groove 16 opened on one side of the side shell 9 provides guidance for the movement of the hard pipe 13, ensures the smooth movement of the hard pipe 13 along the length direction of the worm shaft 7, and covers the whole area of the worm shaft 7.

[0036] The folding back mechanism includes a hydraulic telescopic rod 15 fixedly clamped at one end inside the side shell 9, and a clamping block 14 fixedly connected at the telescopic end of the hydraulic telescopic rod 15, which is fixedly sleeved outside the hard pipe 13 and slidably attached to the inner wall of the sliding groove 16 on both sides;

[0037] When the hydraulic telescopic rod 15 is telescoped, the clamping block 14 is reciprocally slid along the sliding groove 16, thereby synchronously driving the hard pipe 13 and the oil brushing mechanism below the hard pipe 13 to move, so that the oil brushing mechanism can cover the root of the spiral groove, the tooth top and other easily-worn areas of the worm shaft 7, and solve the problem that the blind area difficult to be reached by manual lubrication.

[0038] The oil injection mechanism includes a volumetric lubricating pump 5, a connector pipe 6 connected and installed inside the upper part of the volumetric lubricating pump 5, the volumetric lubricating pump 5 is fixedly installed on the upper surface of one side of the shell 3, a telescopic hose 12 is connected and installed inside the lower part of the volumetric lubricating pump 5, the lower end of the telescopic hose 12 is connected with the hard pipe 13, and heat dissipation grilles 4 are respectively installed on both sides of the shell 3 and close to the upper part;

[0039] The volumetric lubricating pump 5 is fixedly installed on the upper surface of one side of the shell 3, and the connector pipe 6 connected and installed inside the upper part of the volumetric lubricating pump 5 is used to connect with the external lubricating grease supply source, so as to accurately control the output amount of the lubricating grease;

[0040] The telescopic hose 12 connected and installed inside the volumetric lubricating pump 5 is connected with the hard pipe 13, can be flexibly telescoped with the movement of the hard pipe 13, prevents the pipeline from being damaged due to pulling, and the lubricating grease is delivered to the hard pipe 13 through the telescopic hose 12 and then distributed to the oil brushing mechanism;

[0041] The heat dissipation grilles 4 can assist in discharging the heat inside the shell 3, avoid the abnormal change of the lubricating grease caused by high temperature, and extend to the open lower part of one side of the shell 3, so as to add a precise filter screen to prevent impurities from entering.

[0042] The brush oil mechanism comprises a clamping shell 24 clamped outside the fixed block 25, a frame 30 fixedly installed on the side of the clamping shell 24 away from the fixed block 25, a first U-shaped frame 19 fixedly installed outside one end of the frame 30 in a vertical manner, nylon brushes 18 installed on the outer surface of the first U-shaped frame 19 in a vertical direction at equal distances, two groups of symmetrical mounting holes respectively formed in the upper surface of the clamping shell 24, and mounting screws 23 threadedly connected inside the mounting holes and extended to the inside of the fixed block 25 at the bottom ends.

[0043] The clamping shell 24 can be connected to the fixed block 25 through the mounting screws 23, which can be conveniently disassembled in the later period, and the hole surface inside the mounting hole is a threaded surface.

[0044] Under the extension drive of the hydraulic extension rod 15, the structures such as the hard pipe 13, the nylon brushes 18, the first U-shaped frame 19, the clamping shell 24 and the frame 30 are synchronously transversely moved, and the nylon brushes 18 can uniformly brush the lubricating grease sprayed from the hard pipe 13 on the outer surface of the worm shaft 7 along with the movement of the hard pipe 13.

[0045] It should be emphasized that the nylon brushes 18 are made of nylon wires with low hardness, which is much lower than the material hardness of the worm shaft 7, and the nylon wires have a certain elastic deformation capacity. When the worm shaft 7 rotates, the friction force generated when the nylon brushes 18 contact the surface of the worm shaft 7 is extremely small, and the helical grooves at both ends of the worm shaft 7 are formed in the middle. Therefore, spaces for the nylon brushes 18 to stop are reserved at both ends during coating, and the friction degree does not affect the transmission of the worm shaft 7 because the nylon brushes 18 stick to the lubricating grease during the coating process.

[0046] A high-pressure air pump 26 is fixedly clamped inside the rear end of the frame 30, a vertical pipe 22 is fixedly installed at one end of the high-pressure air pump 26, the vertical pipe 22 is vertically inserted into the first U-shaped frame 19, and a shunt mechanism is arranged inside the vertical pipe 22. The shunt mechanism comprises atomizing nozzles 28 installed in the vertical pipe 22 at equal distances in a vertical direction, and electromagnetic induction heating devices 29 fixedly sleeved outside the atomizing nozzles 28. The atomizing nozzles 28 penetrate the outside of the first U-shaped frame 19, and are correspondingly arranged between the two groups of nylon brushes 18 close to each other.

[0047] The high-pressure air pump 26 inside the rear end of the frame 30 can provide high-pressure airflow, which is delivered to the shunt mechanism through the vertical pipe 22. The atomizing nozzles 28 in the shunt mechanism can spray high-pressure airflow to shuttle between the two groups of nylon brushes 18 close to each other to process the lubricating oil adhered to the outer surface of the nylon brushes 18. The electromagnetic induction heating devices 29 fixedly sleeved outside the atomizing nozzles 28 can heat the lubricating grease to reduce the viscosity and avoid plugging the nozzles.

[0048] The electromagnetic induction heating device 29 is composed of an induction coil, an electromagnetic core and other structures, which is a common prior art and will not be described in detail.

[0049] The second U-shaped frame 20 is internally fixedly clamped with a probe 21, and the rear end of the probe 21 is electrically connected with a temperature sensing buzzer 27 which is fixedly installed on the outer wall of the second U-shaped frame 20.

[0050] The probe 21 can continuously detect the temperature of the surface and lubricating grease of the worm shaft 7 during the travel, and then transmit the temperature to the temperature sensing buzzer 27. The temperature sensing buzzer 27 remains standby under the preset normal working condition of 50-65℃, and immediately issues an alarm when the temperature abnormally rises, reminding the troubleshooting of friction or lubrication problems.

[0051] Working principle: the motor 2 on one side of the base 1 is powered on and runs, and its output shaft directly drives the worm shaft 7 in the shell 3 to rotate. The worm shaft 7 meshes with the planetary gears in the planetary gear module 8 through the helical tooth surface, and disperses and transmits power to multiple planetary gears. The planetary gears are driven by the worm shaft 7 to simultaneously revolve around their own axes and revolve around the axis of the worm shaft 7, and the dispersed power is collected to the transmission shaft 31 through the meshing with the inner ring gear. Finally, the power is outputted to the outside through the transmission shaft 31 penetrating the fixed seat 32 and the shell 3, which meets the transmission demand of large transmission ratio and high load. In this process, the heat generated by the internal operation is simultaneously discharged to the outside through the heat dissipation grilles 4 on both sides of the shell 3, so as to maintain the stability of the transmission environment temperature.

[0052] At the same time of power transmission, the automatic lubrication system also realizes the precise lubrication of the surface of the worm shaft 7 according to the use of the worm shaft 7. The volumetric lubrication pump 5 on the upper surface of one side of the shell 3 is connected to the external lubricating grease supply source through the joint pipe 6, pressurizes the lubricating grease, and then delivers it to the hard pipe 13 through the flexible hose 12, and sprays it to the outer surface of the worm shaft 7 through the hard pipe 13. At this time, the folding mechanism in the side shell 9 starts to act, and the hydraulic telescopic rod 15 drives the clamping block 14 fixedly sleeved outside the hard pipe 13 to slide along the sliding groove 16, so as to make the hard pipe 13 and the brush oil mechanism on both sides move back and forth with the clamping block 14, covering the full length of the worm shaft 7, avoiding the lubrication blind area, and the nylon brush 18 on the outer surface of the first U-shaped frame 19 moves with the hard pipe 13, further brushing the lubricating grease to the root of the helical groove, the addendum and other easy-wear areas of the worm shaft 7, so as to ensure that the lubricating grease fully penetrates into the meshing gap between the worm shaft 7 and the planetary gear module 8, reduces the sliding friction, and after the lubrication is completed, the high-pressure gas pump 26 in the frame 30 delivers high-pressure gas flow to the vertical pipe 22, and the vertical pipe 22 sprays the gas flow from the atomizing nozzles 28 distributed at equal distances along the vertical direction through the flow distribution mechanism, blows the excess lubricating oil adhered to the outer surface of the nylon brush 18, and the electromagnetic induction heating device 29 outside the atomizing nozzle 28 synchronously heats the lubricating grease to reduce its viscosity to prevent the nozzle from being blocked.

[0053] During the operation of the device, the temperature monitoring and early warning mechanism monitors the working condition in real time, avoids abnormal risks, the probe 21 in the second U-shaped frame 20 continuously detects the temperature of the surface of the worm shaft 7 and the lubricating grease, and transmits the temperature signal to the temperature sensing buzzer 27; when the temperature is in the normal range of 50-65℃, the volumetric lubricating pump 5 maintains the normal output, and the oil brushing mechanism reciprocates at the preset frequency; if the temperature abnormally rises, such as more than 80℃, it indicates that the friction is intensified, the temperature sensing buzzer 27 immediately gives an alarm, and at the same time, the volumetric lubricating pump 5 automatically increases the output of the lubricating grease, cooperates with the action of the oil brushing mechanism to strengthen the lubrication, and inhibits the further intensification of the friction; when maintenance is needed in the later period, only the installation screws 23 on the clamping shell 24 need to be disassembled, the oil brushing mechanism can be taken off from the fixed block 25, the nylon brush 18 is replaced or the atomizing nozzle 28 is cleaned, and the whole device does not need to be disassembled, so that the maintenance convenience is ensured.

[0054] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
