Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a right-angle planetary reducer with a bevel gear reversing mechanism. Background Art

[0002] A planetary reducer is a device that uses the principle of planetary gear transmission to achieve deceleration. It is mainly composed of a sun gear, planetary gears, a ring gear and a planetary carrier. Its advantages lie in its compact structure, high transmission efficiency, large reduction ratio and the ability to achieve coaxial output. Planetary reducers are widely used in many fields. In right-angle planetary reducers, the bevel gear reversing mechanism is combined with the planetary gear transmission to achieve the function of both deceleration and changing the direction of power.

[0003] Traditional planetary reducers can only achieve coaxial output and cannot meet the needs of right-angle output. Therefore, in many specific working scenarios, traditional planetary reducers cannot work, resulting in the inability to work. In addition, the right-angle planetary reducers with bevel gear reversing mechanisms currently on the market also have complex structures, making the installation and replacement of bevel gears very difficult, requiring a lot of time and energy from the staff, affecting work efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a right-angle planetary reducer with a bevel gear reversing mechanism.

[0005] The technical solution adopted to solve the above technical problems is: a right-angle planetary reducer with a bevel gear reversing mechanism, comprising a box body, the interior of the box body is slidably connected to two sliding blocks, and the outer walls of the two sliding blocks are both provided with a limiting mechanism;

[0006] The insides of the two sliding blocks are both rotatably connected with bearings, the outside of one of the bearings is fixedly connected with an input shaft, and the front end of the other bearing is fixedly connected with an output shaft, the inner ends of the two bearings are both provided with quick installation and removal mechanisms, and the outer walls of the two quick installation and removal mechanisms are both installed with conical teeth;

[0007] A dripping mechanism is arranged on the top of the box.

[0008] Furthermore, the limiting mechanism includes a limiting block fixedly connected to the bottom of the sliding block, both sides of the sliding block are fixedly connected to limiting strips, the inner ends of multiple limiting strips are installed with a first spring, and the other ends of multiple limiting strips are rotatably connected with fixing screws.

[0009] Through the above technical solution, after the internal parts of the sliding block are installed, it is only necessary to push the sliding block inside the box. At this time, the limit bars below and on both sides of the sliding block will limit the movement trajectory of the sliding block, so that it can only move in the specified direction, and during the movement, the limit bar will also apply pressure to the first spring until the sliding block moves to the specified position. The staff can fix the sliding block inside the box by turning the two fixing screws. When parts need to be replaced, it is only necessary to turn the fixing screws. At this time, the sliding block will automatically pop out of the box under the action of the elastic force of the first spring, which is convenient for the staff to carry out subsequent dangerous replacement work.

[0010] Furthermore, an inner wall of the box body is provided with a mounting groove corresponding to the first spring, and the first spring is installed between the box body and the limiting strip.

[0011] Through the above technical solution, the installation groove provides a precise installation position for the first spring. By installing the first spring in a specific installation groove, the position of the first spring can be effectively limited to prevent it from shaking or shifting randomly in the box, thereby ensuring the stability of the entire structure. The first spring is installed between the box and the limit bar to form a mutually cooperative structural system. The pressure of the first spring will act on the sliding block through the limit bar, so that it can be popped out.

[0012] Furthermore, the quick installation and removal mechanism includes a mounting bar installed on the inner end of the input shaft, the inner end of the mounting bar is rotatably connected to two rotating bars, one side of the two rotating bars is fixedly connected to a fixed round block, the outer wall of the mounting bar is provided with two mounting holes, the inside of the two mounting holes are installed with connecting springs, and the other ends of the two connecting springs are fixedly connected to a fixed block.

[0013] Through the above technical solution, when it is necessary to install the conical tooth, it is only necessary to align the conical tooth with the mounting strip and insert it into it. During the sliding process of the conical tooth on the mounting strip, the fixing block inside the mounting strip will enter the fixing hole corresponding to the conical tooth under the elastic force of the connecting spring to form a preliminary fixation. When the conical tooth is completely inserted into the outer wall of the mounting strip, it is only necessary to rotate and lay the two rotating strips flat so that the fixing round blocks on the two rotating strips can be connected to the holes of the conical tooth to complete the final installation work. When the conical tooth needs to be replaced, the limit strip is rotated at this time so that it no longer has a restrictive effect on the conical tooth. The conical tooth is moved, and the fixing block inside the conical tooth will retract into the mounting hole under the action of manpower. At this time, the fixing block will not restrict the conical tooth, and the staff can easily remove the conical tooth, which is very convenient and quick.

[0014] Furthermore, the two conical teeth mesh with each other.

[0015] Through the above technical solution, the two mutually meshing conical teeth can effectively change the direction of power transmission. This meshing method can accurately convert the horizontal power of the input shaft into the vertical power of the output shaft, meeting the specific requirements of different components in the equipment for power direction.

[0016] Furthermore, the dripping mechanism includes an oil storage tank installed on the top of the box body, the outer wall of the oil storage tank is fixedly connected to an oil pipe, the outer wall of the oil pipe is installed with an electric oil dripping valve, the other end of the oil pipe is fixedly connected to an oil dripping nozzle, the top of the box body is fixedly connected to a signal processor near the oil storage tank, a controller is installed inside the signal processor, the bottom wire of the signal processor is connected to a speed sensor, the bottom of the box body is fixedly connected to an oil collecting pan, and the bottom of the oil collecting pan is fixedly connected to a waste liquid pipe.

[0017] Through the above technical solution, the speed sensor will monitor the speed of the two conical teeth in real time, and the generated electrical signal will be transmitted to the signal processor, which will be transmitted to the controller for processing and control. Finally, the processed signal will be transmitted to the electric oil drip valve, which will execute the command and provide suitable lubricating oil to the oil drip nozzle. The lubricating oil will be dripped onto the meshing point of the two conical teeth through the oil drip nozzle to help the two conical teeth rotate better, and the oil collecting pan will discharge the lubricating oil flowing from the meshing point of the conical teeth through the waste pipe.

[0018] Furthermore, the oil drip nozzle is installed above the mutual meshing position of the two conical teeth.

[0019] Through the above technical solution, the oil drip nozzle is installed above the meshing area of ​​the two conical teeth, which can ensure that the lubricating oil drips directly onto the meshing area of ​​the tooth surfaces. Through this precise oil dripping position, the lubricating oil can form an oil film at the moment of tooth surface contact, effectively reducing the friction coefficient between the tooth surfaces and reducing the energy loss and tooth surface wear caused by friction.

[0020] Furthermore, the top of the oil collecting pan is tightly fitted to the bottom of the box body, and an oil outlet is provided at the bottom of the box body.

[0021] Through the above technical solution, the top of the oil collecting pan fits tightly to the bottom of the box, which can ensure that the lubricating oil flowing from the meshing of the conical teeth is completely collected. The tight-fitting design can also prevent the lubricating oil from dripping to the ground, reducing safety hazards and environmental pollution.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention realizes real-time monitoring of the operating status of the equipment by designing a dripping mechanism, and the speed sensor is connected to the lubrication system through a signal processor. By monitoring the speed of the conical teeth, it can not only be used to control the oil dripping process, but also serve as an important indicator of the overall operating status of the equipment, helping the device to better transmit power; (2) The present invention designs a quick installation and removal mechanism. This installation method only requires the conical teeth to be aligned with the installation bar and plugged in. The operation is simple and direct. Compared with the traditional complex installation method, there is no need to use multiple tools to perform tedious alignment, tightening and other steps. When the conical teeth need to be removed, it is only necessary to rotate the rotating bar to disengage the fixed round block from the hole of the conical teeth, and then overcome the elastic force of the connecting spring to pull out the conical teeth. This simple disassembly step does not require complex tools or professional skills. Maintenance personnel can quickly complete the disassembly operation, which is conducive to the rapid inspection and maintenance of the equipment; (3) The present invention designs a limit mechanism. Since the movement path of the sliding block is limited, it is easier for the staff to operate when pushing the sliding block into the box. There is no need to spend a lot of time and effort to accurately adjust the position of the sliding block. You only need to push it in the direction specified by the limit mechanism. When parts need to be replaced, after turning the fixing screw, the sliding block will automatically pop out of the box under the elastic force of the first spring. This automatic pop-up design greatly facilitates the staff to disassemble the sliding block and its internal parts. Compared with the traditional method that requires the use of tools to pry or disassemble complex connection structures, it reduces the workload and difficulty of disassembly and improves the efficiency of equipment maintenance.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] like Figure 1 - Figure 3 As shown, a right-angle planetary reducer with a bevel gear reversing mechanism in this embodiment includes a housing 1, and two sliding blocks 2 are slidably connected inside the housing 1.

[0034] like Figure 4 As shown, the outer walls of the two sliding blocks 2 are provided with a limiting mechanism 3, which includes a limiting block 301 fixedly connected to the bottom of the sliding block 2, and limiting strips 302 are fixedly connected to both sides of the sliding block 2. The inner ends of multiple limiting strips 302 are installed with first springs 303, and the other ends of multiple limiting strips 302 are rotatably connected with fixing screws 304. When the sliding block 2 has installed the internal parts, it is only necessary to push the sliding block 2 inside the box body 1. At this time, the limiting strips 302 below and on both sides of the sliding block 2 will limit the movement trajectory of the sliding block 2 so that it can only move in a specified direction. In addition, during the movement, the limiting strips 302 will also apply pressure to the first spring 303. Until the sliding block 2 moves to the specified position, the staff can fix the sliding block 2 inside the box body 1 by rotating the two fixing screws 304. When it is necessary to replace parts, it is only necessary to rotate the fixing screws 304. At this time, the sliding block 2 will also automatically pop out of the box body 1 under the elastic force of the first spring 303, which is convenient for the staff to carry out subsequent work.

[0035] like Figure 4As shown, the inner wall of the box body 1 is provided with a mounting groove corresponding to the first spring 303, and the first spring 303 is installed between the box body 1 and the limiting strip 302. The mounting groove provides a precise mounting position for the first spring 303. By installing the first spring 303 in a specific mounting groove, the position of the first spring 303 can be effectively limited to prevent it from shaking or shifting randomly in the box body 1, thereby ensuring the stability of the entire structure. The first spring 303 is installed between the box body 1 and the limiting strip 302 to form a mutually cooperative structural system. The pressure of the first spring 303 will act on the sliding block 2 through the limiting strip 302, so that it can be ejected.

[0036] like Figure 2 - Figure 4 As shown, the two sliding blocks 2 are both rotatably connected with bearings 4 inside, the outer side of one of the bearings 4 is fixedly connected with an input shaft 5, and the front end of the other bearing 4 is fixedly connected with an output shaft 6.

[0037] like Figure 5 and Figure 6 As shown, the inner ends of the two bearings 4 are both provided with a quick installation and removal mechanism 7, and the quick installation and removal mechanism 7 includes a mounting bar 701 mounted on the inner end of the input shaft 5, the inner end of the mounting bar 701 is rotatably connected to two rotating bars 702, one side of the two rotating bars 702 is fixedly connected to a fixed round block 703, the outer wall of the mounting bar 701 is provided with two mounting holes 704, the interiors of the two mounting holes 704 are both provided with connecting springs 705, the other ends of the two connecting springs 705 are both fixedly connected to a fixing block 706, and the outer walls of the two quick installation and removal mechanisms 7 are both provided with conical teeth 8, the two conical teeth 8 are meshed with each other, and the two meshing conical teeth 8 can effectively change the direction of power transmission, and this meshing The method can accurately convert the horizontal power of the input shaft 5 into the vertical power of the output shaft, meeting the specific requirements of different components in the equipment for the power direction. When the conical gear 8 needs to be installed, it is only necessary to align the conical gear 8 with the mounting bar 701 and insert it. When the conical gear 8 slides on the mounting bar 701, the fixing block 706 inside the mounting bar 701 will enter the fixing hole corresponding to the conical gear 8 under the elastic force of the connecting spring 705, forming a preliminary fixation. When the conical gear 8 is fully inserted into the outer wall of the mounting bar 701, it is only necessary to rotate and lay the two rotating bars 702 flat so that the fixing round blocks 703 on the two rotating bars 702 can be connected to the holes of the conical gear 8 to complete the final installation work.

[0038] like Figure 5 and Figure 6As shown, when the conical tooth 8 needs to be replaced, the limit bar 302 is rotated so that it no longer has a restrictive effect on the conical tooth 8. The conical tooth 8 is moved, and the fixed block 706 inside the conical tooth 8 will retract into the mounting hole 704 under the action of manpower. At this time, the fixed block 706 will not restrict the conical tooth 8, and the staff can easily remove the conical tooth 8, which is very convenient and quick.

[0039] like Figure 7 and Figure 8 As shown, a dripping mechanism 9 is provided on the top of the box body 1, and the dripping mechanism 9 includes an oil storage tank 901 installed on the top of the box body 1, and an oil pipe 902 is fixedly connected to the outer wall of the oil storage tank 901, and an electric oil dripping valve 903 is installed on the outer wall of the oil pipe 902, and an oil dripping nozzle 904 is fixedly connected to the other end of the oil pipe 902, and the oil dripping nozzle 904 is installed at the upper position where the two conical teeth 8 are meshed with each other. Installing the oil dripping nozzle 904 at the upper position where the two conical teeth 8 are meshed with each other can ensure that the lubricating oil drips directly into the meshing area of ​​the tooth surface. Through this precise oil dripping position, the lubricating oil can form an oil film at the moment when the tooth surface contacts, effectively reducing the friction coefficient between the tooth surfaces, reducing the energy loss and gear wear caused by friction. The surface is worn. A signal processor 905 is fixedly connected to the top of the casing 1 near the oil storage tank 901. A controller 906 is installed inside the signal processor 905. The bottom wire of the signal processor 905 is connected to a speed sensor 907. An oil collecting pan 908 is fixedly connected to the bottom of the casing 1. The top of the oil collecting pan 908 fits tightly to the bottom of the casing 1, and an oil outlet is provided at the bottom of the casing 1. The top of the oil collecting pan 908 fits tightly to the bottom of the casing 1, which can ensure that the lubricating oil flowing from the meshing of the conical teeth 8 is completely collected. The tight-fitting design can also prevent the lubricating oil from dripping to the ground, reducing safety hazards and environmental pollution. A waste liquid pipe 909 is fixedly connected to the bottom of the oil collecting pan 908.

[0040] like Figure 7 and Figure 8 As shown, the speed sensor 907 will monitor the speed of the two conical teeth 8 in real time, and the generated electrical signal will be transmitted to the signal processor 905, which will transmit it to the controller 906 for processing and control.

[0041] The working principle of this embodiment is as follows: by rotating the fixing screw 304, the sliding block 2 will automatically pop out of the box body 1 under the elastic force of the first spring 303, so that the staff can install or replace the conical gear 8. They only need to align the conical gear 8 with the mounting strip 701 and insert it. When the conical gear 8 slides on the mounting strip 701, the fixing block 706 inside the mounting strip 701 will enter the fixing hole corresponding to the conical gear 8 under the elastic force of the connecting spring 705 to form a preliminary fixation. When the conical gear 8 is completely inserted into the outer wall of the mounting strip 701, it is only necessary to rotate and lay the two rotating strips 702 flat so that the fixing round blocks 703 on the two rotating strips 702 can be connected to the holes of the conical gear 8. After the installation of the conical gear 8 and the sliding block 2 is completed;

[0042] The input shaft 5 is rotated to drive the conical tooth 8 connected to the input shaft 5 to rotate, thereby driving the other conical tooth 8 to rotate, and finally outputting power through the output shaft 6.
