Description

Technical Field

[0001] This utility model relates to the field of robot reducer technology, specifically a bevel gear for easy maintenance of robot reducers. Background Technology

[0002] When assembling robot parts, reducers are required. Reducers typically consist of one or more pairs of reduction gears. Power is input from the driving gear and output through the driven gear to achieve a reduction effect. Currently used robot reducers mostly employ a one-piece bevel gear structure, making quick disassembly and maintenance difficult after wear, thus affecting work efficiency. Therefore, designing a bevel gear for robot reducers that is easy to maintain is crucial. For example:

[0003] The bevel gear structure of the reducer, authorized by announcement number CN217440731U, includes a bevel gear body, an oil reservoir, and a connecting shaft. A shaft hole is provided in the middle of one side of the bevel gear body. An oil reservoir is provided on one side of the bevel gear body, and several oil guide pipes are fixedly provided on one side of the oil reservoir. Several conical serrations are evenly spaced on one side of the bevel gear body along the oil guide pipes. Several oil outlet holes are provided on one side of the conical serrations. A fixing sleeve is fixedly connected to the other side of the bevel gear body, and a fixing tube is rotatably connected to one end of the fixing sleeve. Compared with the prior art, the beneficial effects of this utility model are: The utility model involves inserting a limiting strip at one end of the connecting shaft into a limiting groove on the fixing sleeve, and then threading the fixing tube to the connecting shaft. During installation, this prevents the bevel gear structure from reversing, thus preventing loosening and increased wear between components, extending the service life of the bevel gear structure, and facilitating connection with external devices. By setting the conical sawtooth to an arc shape, during the rotation of the bevel gear body, centrifugal force allows the ejected oil to slide along the arc surface of the conical sawtooth, increasing the lubrication area, improving the lubrication effect, and further extending the service life of the bevel gear body.

[0004] Based on existing solutions and actual production and processing applications, the bevel gears used in existing robot reducers have the following defects, such as:

[0005] While existing bevel gears used in robot reducers allow the ejected oil to slide along the arc surface of the conical teeth, thereby increasing the lubrication area and improving the lubrication effect, they are mostly one-piece structures, making it difficult to quickly disassemble and maintain them after wear, which affects work efficiency. Therefore, this utility model provides a bevel gear for robot reducers that is easy to maintain, in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a bevel gear for robot reducers that is easy to maintain, in order to solve the problem mentioned in the background art that although the bevel gears used in existing robot reducers can make the splashed oil slide along the arc surface of the conical saw teeth, thereby increasing the lubrication area and improving the lubrication effect, they are mostly one-piece structures, which makes it difficult to quickly disassemble and maintain them after wear, thus affecting work efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bevel gear for robot reducers that is easy to maintain, comprising a first connecting plate, a driven wheel being provided at the right end of the first connecting plate, a driving wheel being connected to the lower side of the driven wheel, and a protective cover being provided on the outer side of the driving wheel;

[0008] Also includes:

[0009] A connecting frame is provided inside the protective cover, and a protective structure is provided on the lower side of the connecting frame. A second connecting plate is installed at the lower end of the drive wheel, and a connecting sleeve is provided at the lower end of the second connecting plate. A connector is provided inside the connecting sleeve, and a transmission rod is installed at the lower end of the connector.

[0010] The limit rod is actually inside the connector, and the transmission rod is connected to the outside of the connector.

[0011] Preferably, the driven wheel is meshed with the driving wheel, and the diameter of the driven wheel is larger than the diameter of the driving wheel.

[0012] Preferably, a second connecting block is installed on the upper end of the drive wheel, and a second positioning rod is provided on the upper end of the second connecting block, and the second positioning rod is slidably connected to the protective cover.

[0013] Preferably, a first connecting block is arranged parallel to the right end of the driven wheel, and a first positioning rod is vertically connected to the right end of the first connecting block, and the first positioning rod is slidably connected to the protective cover.

[0014] Preferably, the connecting sleeve and the connecting head are engaged and connected, and the longitudinal section of the connecting head has a "T" shaped structure.

[0015] Preferably, the limiting rod passes through the interior of the connecting sleeve and the connector, and the outer side of the limiting rod is provided with limiting wheels that are symmetrically distributed on the left and right.

[0016] Preferably, the protective structure includes a first protective plate disposed on the lower side of the connecting frame, and the connecting frame and the protective cover are engaged and connected to each other.

[0017] Preferably, the interior of the first protective plate is penetrated by a connecting sleeve, and the inner side of the first protective plate is threaded with a first connecting bolt, and the first connecting bolt is symmetrically arranged about the center line of the first protective plate.

[0018] Preferably, the left side of the first connecting plate is engaged with the second protective plate, and the inner side of the second protective plate is threaded with a second connecting bolt, and the second connecting bolt is arranged symmetrically about the center line of the second protective plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the bevel gear for robot reducer is easy to maintain. By designing the bevel gear for robot reducer in a split manner, it can be effectively disassembled and replaced, so that staff can maintain it. At the same time, the bevel gear for robot reducer is isolated from the outside world, which can improve the protection function of the bevel gear for robot reducer.

[0020] It is equipped with a limit rod and a connector. The connector is engaged with the connecting sleeve. The limit rod is horizontally inserted and limit wheels are screwed on at both ends of the limit rod. The connector is fastened to the connecting sleeve.

[0021] The device is equipped with a protective cover and a second positioning rod. By fully inserting the drive wheel and the second connecting plate into the cavity at the lower end of the protective cover until the upper end of the second positioning rod contacts the protective cover, the connecting sleeve at the left end of the first connecting plate is pushed until the right end of the first positioning rod contacts the protective cover. The function of the first positioning rod and the second positioning rod is to position the driven wheel and the drive wheel when they rotate inside the protective cover, so as to realize the positioning and anti-deviation function of the bevel gear of the robot reducer.

[0022] The system includes a first protective plate and a second protective plate. By pressing the first protective plate upwards until its upper surface contacts the bottom section of the protective cover, and then vertically screwing on the first connecting bolt, the first protective plate is secured to the protective cover. Similarly, under the action of the second connecting bolt, the second protective plate is securely connected to the protective cover. The driven wheel and the driving wheel are protected in the internal cavity of the protective cover, which facilitates the protection of the bevel gears used in the robot reducer.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a bevel gear for robot reducers that is easy to maintain, comprising a first connecting plate 1, a driven wheel 2, a driving wheel 3, a protective cover 4, a first connecting block 5, a first positioning rod 6, a second connecting block 7, a second positioning rod 8, a second connecting plate 9, a connecting sleeve 10, a limiting rod 11, a limiting wheel 12, a connector 13, a transmission rod 14, a connecting frame 15, a first protective plate 16, a first connecting bolt 17, a second protective plate 18, and a second connecting bolt 19.

[0031] Specific examples Figure 1 , Figure 3 and Figure 5As shown, the drive wheel 3 is first placed horizontally. A second connecting plate 9 is located at the bottom of the drive wheel 3. After the connecting sleeve 10 at the lower end of the second connecting plate 9 passes through the interior of the first protective plate 16, the connector 13, with a "T"-shaped longitudinal section, is aligned with the lower opening of the connecting sleeve 10. The transmission rod 14, located at the lower end of the connector 13, is pushed. When the transmission rod 14 is pushed, friction occurs between the outer wall of the connector 13 and the inner wall of the connecting sleeve 10, causing the connector 13 and the connecting sleeve 10 to slide together until the upper end face of the connector 13 contacts the connecting sleeve 10. At this point, the connector 13 and the connecting sleeve 10 are engaged. The connection between the head 13 and the connecting sleeve 10 is horizontally penetrated by the limiting rod 11. Both ends of the limiting rod 11 are provided with threaded structures. Two sets of ring-shaped limiting wheels 12 are selected. After aligning the center hole of the limiting wheel 12 with the left and right ends of the limiting rod 11, they are screwed inward. The two sets of limiting wheels 12 tighten inward, shortening the connection gap between the connecting head 13 and the connecting sleeve 10. The connecting head 13 and the connecting sleeve 10 are then tightly connected. Similarly, after the connecting sleeve 10 at the left end of the first connecting plate 1 penetrates the interior of the second protective plate 18, the connecting sleeve 10 and the connecting head 13 are tightly connected, which facilitates the quick disassembly and maintenance of the bevel gear of the robot reducer.

[0032] Specific examples Figure 1 and Figure 2 As shown, the protective cover 4 is placed horizontally. The second positioning rod 8 is aligned with the lower opening of the protective cover 4 and pushed. The second positioning rod 8 is located on the upper end of the second connecting block 7, which is installed parallel to the upper end of the drive wheel 3. The connecting sleeve 10 is pushed upward so that the drive wheel 3 and the second connecting plate 9 are fully inserted into the cavity at the lower end of the protective cover 4. During the pushing process, friction is generated between the outer wall of the second positioning rod 8 and the inner wall of the protective cover 4, and the second positioning rod 8 slides with the protective cover 4 until the upper end face of the second positioning rod 8 contacts the protective cover 4. Similarly, the driven wheel 2 is placed vertically, and the connecting sleeve 10 at the left end of the first connecting plate 1 is pushed so that the driven wheel 2 is aligned with the opening at the left end of the protective cover 4. During movement, a first connecting block 5 is provided at the right end of the driven wheel 2, and a first positioning rod 6 is vertically provided at the right end of the first connecting block 5. During the pushing process, friction is generated between the outer wall of the first positioning rod 6 and the inner wall of the protective cover 4, and the first positioning rod 6 and the protective cover 4 are slidably connected until the right end face of the first positioning rod 6 contacts the protective cover 4. At this time, the right end face of the first connecting block 5 is connected to the inner wall of the protective cover 4, and the first connecting plate 1 and the driven wheel 2 are fully inserted into the cavity at the left end of the protective cover 4. The function of the first positioning rod 6 and the second positioning rod 8 is to play a positioning role when the driven wheel 2 and the driving wheel 3 rotate inside the protective cover 4, so as to realize the positioning and anti-deviation function of the bevel gear of the robot reducer.

[0033] Specific examples Figure 1 and Figure 4 As shown, when the second connecting block 7 at the lower end of the second positioning rod 8 contacts the protective cover 4, the first protective plate 16 is pressed upward. The first protective plate 16 is penetrated by the connecting sleeve 10 at the lower end of the second connecting plate 9. A connecting frame 15 is provided at the upper end of the first protective plate 16. During the upward movement of the first protective plate 16, the outer end of the connecting frame 15 is aligned with the lower opening of the protective cover 4 and moves upward. Sliding friction occurs between the outer wall of the connecting frame 15 and the inner wall of the protective cover 4 until the upper end surface of the first protective plate 16 contacts the bottom cross-section of the protective cover 4. At this time, the connecting bracket 15 engages with the protective cover 4. The first connecting bolt 17 is vertically screwed onto the connection between the first protective plate 16 and the protective cover 4. The first connecting bolt 17 has a threaded structure on its exterior. When the first connecting bolt 17 is screwed on, the connection gap between the first protective plate 16 and the protective cover 4 shortens. The first connecting bolt 17 passes through the interior of the first protective plate 16, and is threadedly connected to both the protective cover 4 and the first protective plate 16. Under the action of the first connecting bolt 17, the first protective plate 16 and the protective cover 4 are tightened. Under the action of the second connecting bolt 19, the second protective plate 18 is fastened to the protective cover 4. The second protective plate 18, the protective cover 4, and the first protective plate 16 form a sealed space, protecting the driven wheel 2 and the driving wheel 3 inside the cavity of the protective cover 4. When the transmission rod 14 rotates and drives the connecting sleeve 10 to move through the upper connecting head 13, the second connecting plate 9 follows the rotation of the connecting sleeve 10 to drive the driving wheel 3 to move. Sliding friction is generated between the second positioning rod 8 and the protective cover 4, and the driving wheel 3 is engaged with the driven wheel 2. This causes the driven wheel 2 to rotate inside the protective cover 4. The diameter of the driven wheel 2 is larger than that of the driving wheel 3. In the same amount of time, the rotation angle of the driven wheel 2 is smaller than that of the driving wheel 3, thus achieving a deceleration effect. This makes the speed of the connector 13 connected to the left end of the first connecting plate 1 through the connecting sleeve 10 slower than the speed of the connector 13 corresponding to the connecting sleeve 10 at the lower end of the second connecting plate 9, thereby achieving a deceleration effect. This facilitates the protection function of the bevel gear used in the robot reducer. This is the usage method of the bevel gear used in the robot reducer that facilitates maintenance.
