Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically to a power diversion device. Background Technology

[0002] Traditional power sources typically drive only one piece of equipment, with one input and one output shaft, both operating in the same direction. If the axial dimension is too long, it cannot meet assembly requirements when installation space is limited. Currently, on some intelligent production lines, in order to allow multiple machines to operate simultaneously, it is necessary to add a power source. This is not conducive to cost control. In addition, when the machine suddenly loses power, the normal operation of the transmission system cannot be guaranteed, making it unsuitable for intelligent production lines.

[0003] With the continuous development of industry, power sources now need to be shorter and shorter while driving equipment. Although some current devices can switch the power direction and split it into two different directions, this increases the power source and leads to increased production costs. In addition, when the power is off, the load displacement cannot be adjusted by manually adjusting the rotation angle of the device to achieve the required position. Utility Model Content

[0022] Please see Figure 1-7 As shown, one embodiment of the present invention provides a power splitting device, which includes an output component 1, a first input component 2, and a manual input component 3, wherein: Output component 1 includes a housing 11, an output shaft 13, and an output bevel gear 14. The output shaft 13 is rotatably mounted on the housing 11 in a first direction, and the output bevel gear 14 is sleeved on the output shaft 13 and located inside the housing 11 on one side. First input component 2 includes a first input shaft disk 21, a first input shaft 22, and a first input bevel gear 26. The first input shaft 22 is rotatably mounted on the first input shaft disk 21, and the first input bevel gear 26 is sleeved on one end of the first input shaft 22. Manual input component 3 includes a second input shaft disk 31, a hand crank 32, and a second input bevel gear 36. The hand crank 32 is rotatably mounted on the second input shaft disk 31, and the second input bevel gear 36 is sleeved on one end of the hand crank 32.

[0023] The housing 11 has a first opening on each side along the first direction and a second opening on each side along the second direction. The two ends of the output shaft 13 extend out of the corresponding first openings. The first input shaft disk 21 is mounted on one of the second openings, and the first input bevel gear 26 is located inside the housing 11. The second input shaft disk 31 is mounted on the other second opening, and the second input bevel gear 36 is located inside the housing 11. The two sides of the output bevel gear 14 mesh with the first input bevel gear 26 and the second input bevel gear 36 respectively. The first direction and the second direction are perpendicular to each other in the plane.

[0024] Specifically, in this embodiment, when power is input from the first input component 2, the power is transmitted to the first input bevel gear 26 via the first input shaft 22. Since the output bevel gear 14 meshes with the first input bevel gear 26, the power is transmitted from the first input bevel gear 26 to the output bevel gear 14, thereby driving the output shaft 13 to rotate. Similarly, when the manual input component 3 is working, the second input bevel gear 36 is driven to rotate via the hand crank shaft 32. The second input bevel gear 36 meshes with the output bevel gear 14, also transmitting power to the output shaft 13. This structure can realize power output to the same output shaft 13 by two input methods (power input from the first input component and manual input from the manual input component), thus achieving the function of power diversion.

[0025] This power splitting device offers two power input methods: the first input component 2 and the manual input component 3. In different application scenarios, the appropriate power input source can be selected based on the actual situation. For example, when an automated power source (such as a motor) is available, power can be input through the first input component 2; when the automated power source malfunctions or manual operation is required, the manual input component 3 can be used. This flexibility greatly improves the applicability and reliability of the equipment.

[0026] By using bevel gear meshing for power transmission, power transmission between spatially intersecting shafts can be achieved. The meshing of the output bevel gear 14 with the first input bevel gear 26 and the second input bevel gear 36 can effectively transmit power input from different directions to the output shaft 13. Bevel gear transmission has the advantages of high transmission efficiency and compact structure, and can achieve reasonable power distribution and transmission within a limited space.

[0027] The design of the housing 11 and the installation positions of the various components allow for an orderly arrangement of these components in three-dimensional space, avoiding structural chaos and wasted space. Simultaneously, the two ends of the output shaft 13 extend beyond the first opening of the housing 11, facilitating connection with other external mechanical components to achieve power output. This structural layout is beneficial for the integration of the entire device and its installation in actual mechanical equipment.

[0028] Specifically, please refer to Figure 2 As shown, the output assembly 1 also includes an output shaft disk 12 mounted on the first opening of the housing 11. The output shaft disk 12 has an output shaft hole 121 facing the first opening, through which the output shaft 13 passes and extends out of the output shaft hole 121.

[0029] Therefore, the output shaft hole 121 provides a precise mounting position for the output shaft 13, allowing it to be stably mounted on the housing 11. This stable mounting method reduces vibration and wobbling of the output shaft 13 during rotation, improving the stability and accuracy of power transmission. Furthermore, when maintenance, repair, or replacement of components inside the output shaft 13 or housing 11 is required, it can be performed directly through the output shaft disc 12 without the need for complex disassembly of the entire housing 11. This greatly improves the convenience of equipment maintenance.

[0030] Specifically, please refer to Figure 3 As shown, the output shaft 13 includes a second output shaft section 132, a first output shaft section 131, and a third output shaft section 133 connected coaxially in sequence. The second output shaft section 132 and the third output shaft section 133 are rotatably supported on the output shaft hole 121 of the corresponding side output shaft disk 12 by a first tapered roller bearing 15 and a first TC skeleton oil seal 16, respectively. The output bevel gear 14 is sleeved on the side of the second output shaft section 132 away from the output shaft disk 12, and the first tapered roller bearing 15 abuts against one end face of the output bevel gear 14. The first output shaft section 131 and the second output shaft section 132 are close to each other at one end and are provided with a first shoulder 1311. The first shoulder 1311 is adapted to abut against the other end face of the output bevel gear 14.

[0031] When power is transmitted to the output shaft 13, the output bevel gear 14 meshes with the input bevel gears (such as the first input bevel gear 26 and the second input bevel gear 36), thereby realizing power transmission. The output shaft 13 is supported on the output shaft disc 12 by the first tapered roller bearing 15 and the first TC skeleton oil seal 16. This design improves the support rigidity of the output shaft 13, reduces vibration and shaking, and thus enhances the structural stability of the entire power splitting device. The first tapered roller bearing 15 also helps to reduce frictional losses during the rotation of the output shaft 13 and improves the efficiency of power transmission. The first TC skeleton oil seal 16 effectively prevents dust, impurities and moisture from entering the bearing and gear areas, protecting internal components from contamination, thereby extending the service life of key components such as the first tapered roller bearing 15 and the output bevel gear 14.

[0032] For further details, please refer to Figure 3 As shown, the first input shaft 22 includes a second input shaft segment 222, a first input shaft segment 221, and a third input shaft segment 223 connected coaxially in sequence. The first input shaft segment 221 is rotatably mounted on the first input shaft disk 21 via a first single-row deep groove ball bearing 23 and a second single-row deep groove ball bearing 24. The second input shaft segment 222 is provided with a second shoulder 2211 at one end close to the first input shaft segment 221, and the end face of the second shoulder 2211 abuts against the first input bevel gear 26 and the second single-row deep groove ball bearing 24, respectively. The end face of the first single-row deep groove ball bearing 23 away from the second single-row deep groove ball bearing 24 is abutted by a first shaft elastic retaining ring 27 embedded in the first input shaft segment 221.

[0033] In this way, when power is input from the first input shaft 22, it passes through the third input shaft segment 223, the first input shaft segment 221 and the second input shaft segment 222 in sequence. The power is transmitted to the first input bevel gear 26 through the second input shaft segment 222, and then to the output bevel gear 14 that meshes with it, thereby driving the output shaft 13 to rotate.

[0034] The first input shaft section 221 is rotatably mounted on the first input shaft disk 21 via a first single-row deep groove ball bearing 23 and a second single-row deep groove ball bearing 24, which effectively reduces the radial and axial movement of the input shaft and improves the rotational accuracy and stability of the input shaft. The second shaft shoulder 2211 allows the first input bevel gear 26 to abut tightly against the second single-row deep groove ball bearing 24, while the first single-row deep groove ball bearing 23 abuts against the first shaft elastic retaining ring 27, enhancing the structural compactness, ensuring tight fit of all components, and improving the reliability and stability of the overall structure. The setting of the first shaft elastic retaining ring 27 facilitates the installation and disassembly of the first single-row deep groove ball bearing 23, and the tight fit of all components makes the assembly of the entire input shaft assembly simpler, improving the convenience of installation and maintenance.

[0035] Preferably, in one embodiment, a first bearing washer 25 is further provided between the first single-row deep groove ball bearing 23 and the second single-row deep groove ball bearing 24, with the end face of the first bearing washer 25 abutting against the first single-row deep groove ball bearing 23 and the second single-row deep groove ball bearing 24 respectively. In this way, the first bearing washer 25 is installed between the two single-row deep groove ball bearings, increasing the supporting stiffness between the bearings and reducing radial and axial movement of the input shaft when rotating at high speed or under heavy load, thereby improving the stability of the input shaft; in addition, the washer can more evenly distribute the load between the two bearings, preventing one bearing from bearing excessive pressure and extending the service life of the bearing.

[0036] Specifically, please refer to Figure 3 As shown, the hand crank shaft 32 includes a fifth input shaft segment 322, a fourth input shaft segment 321, and a sixth input shaft segment 323 connected coaxially in sequence. The fourth input shaft segment 321 is rotatably mounted on the second input shaft disk 31 via a third single-row deep groove ball bearing 33 and a fourth single-row deep groove ball bearing 34. The fifth input shaft segment 322 and the fourth input shaft segment 321 are provided with a third shoulder 3211 at their respective ends close to each other, and the end face of the third shoulder 3211 abuts against the second input bevel gear 36 and the fourth single-row deep groove ball bearing 34 respectively. The end face of the third single-row deep groove ball bearing 33 away from the fourth single-row deep groove ball bearing 34 is abutted by a second shaft elastic retaining ring 37 embedded in the fourth input shaft segment 321.

[0037] Specifically, when installing the hand crank shaft 32, the fourth input shaft section 321 is rotatably supported on the second input shaft disk 31 by the third single-row deep groove ball bearing 33 and the fourth single-row deep groove ball bearing 34. The setting of the third shaft shoulder 3211 allows the second input bevel gear 36 and the fourth single-row deep groove ball bearing 34 to abut tightly, ensuring the stability and accuracy of power transmission. The second shaft is fitted with an elastic retaining ring 37 on the fourth input shaft section 321 to abut against the end face of the third single-row deep groove ball bearing 33, preventing axial movement of the bearing and ensuring the correct installation and positioning of the bearing. The fourth input shaft section 321 is rotatably mounted on the second input shaft disk 31 by two single-row deep groove ball bearings, which can effectively reduce the radial and axial movement of the hand crank shaft and improve the rotational accuracy and stability of the hand crank shaft.

[0038] Please see Figure 4 , 5 As shown, a second flat key 2221 is provided on the outer circumference of the second input shaft segment 222, and the first input bevel gear 26 is circumferentially limited to the second input shaft segment 222 through the second flat key 2221; a third flat key 3221 is provided on the outer circumference of the fifth input shaft segment 322, and the second input bevel gear 36 is circumferentially limited to the fifth input shaft segment 322 through the third flat key 3221.

[0039] In this technical solution, a flat key is installed on the outer circumference of the input shaft section, and the input bevel gear is circumferentially limited and connected to the input shaft section via the flat key. This ensures that power can be effectively transmitted from the input shaft to the bevel gear. This design effectively prevents relative rotation between the input shaft and the bevel gear, ensuring stable power transmission and improving the reliability and efficiency of the entire device. Furthermore, the flat key connection has advantages such as simple structure, reliable operation, and convenient assembly and disassembly, facilitating the installation and maintenance of the bevel gear.

[0040] Please see Figure 4 As shown, the first input bevel gear 26 and the second input shaft segment 222 are axially limited and connected by a first end face locking member 261, and the second input bevel gear 36 and the fifth input shaft segment 322 are also axially limited and connected by a second end face locking member 361. The use of end face locking members effectively prevents axial movement of the input bevel gears during power transmission, ensuring a more secure and reliable connection between the bevel gears and the input shaft segment. This axial limiting design helps improve the stability and accuracy of power transmission, reducing power transmission errors and vibrations caused by axial movement.

[0041] Specifically, please refer to Figure 3 As shown, a first flat key 1321 is provided on the outer circumference of the second output shaft segment 132. The output bevel gear 14 is circumferentially limited and connected to the second output shaft segment 132 through the first flat key 1321. This effectively prevents relative rotation between the output bevel gear 14 and the output shaft 13, ensuring the synchronicity of power transmission. This helps to improve the reliability and efficiency of the entire power splitting device.

[0042] Specifically, please refer to Figure 1 As shown, the output shaft disk 12 is fixedly connected to the housing 11 along the first direction by the first locking member 122, and the first input shaft disk 21 and the second input shaft disk 31 are both fixedly connected to the housing 11 along the second direction by the second locking member 4.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
