Description

Technical Field

[0001] This utility model relates to the field of meshing clearance detection technology, and in particular to an auxiliary device for detecting the meshing clearance of bevel gears. Background Technology

[0002] As a core transmission component of new energy sweeping robots, the meshing clearance of bevel gears directly affects the stability, noise level, and service life of the equipment. Excessive clearance leads to abnormal transmission noise and impact wear, while insufficient clearance causes overheating and jamming. For example... Figure 1 , Figure 2 The bevel gear linkage mechanism of the new energy cleaning robot shown mainly includes a housing, two bevel gears, an output shaft, and an input shaft. The output shaft passes through the housing, and a square boss coaxial with the output shaft is provided on one end face of the housing. One end of the input shaft extends into the housing and is perpendicular to the output shaft. Both bevel gears are housed in the housing and mounted on two drive shafts respectively, and the two bevel gears mesh. Currently, the bevel gear meshing clearance test is performed before the bevel gears are assembled into the housing. One method is to insert a feeler gauge into the top and side clearances of the bevel gears to directly read the clearance size. Another method is to apply resistance to one bevel gear to prevent it from rotating, and then install a dial indicator near the other bevel gear, pressing the indicator's contacts against the tooth surface. By turning the bevel gear, a value will be displayed on the indicator, which reflects the meshing clearance of the bevel gears. This method cannot be used for rapid batch testing. In summary, both methods require testing before the bevel gears are assembled into the housing, which is cumbersome and cannot be used for rapid batch testing. Utility Model Content

[0003] Therefore, in view of the technical problem that the current method of testing the meshing clearance of bevel gears before the bevel gears are assembled into the housing is relatively cumbersome and cannot be used for rapid batch testing, this utility model needs to provide an auxiliary device for testing the meshing clearance of bevel gears.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides an auxiliary device for detecting the meshing clearance of bevel gears, which is used to assist in detecting the meshing clearance of bevel gears in a bevel gear linkage device. The bevel gear linkage device includes a housing, an output shaft, an input shaft, and two bevel gears. The auxiliary device for detecting the meshing clearance of bevel gears includes a base, a clamping component, a clamping component, and an angle gauge. The base is provided with a first support column and a second support column for supporting the housing and the output shaft, respectively. The clamping component is installed on the base and is used to press the output shaft against the second support column to keep the output shaft horizontal. The clamping component is clamped on the input shaft, and applying external force to the clamping component can drive the input shaft to rotate. The angle gauge is installed on the clamping component.

[0005] The bevel gear meshing clearance detection auxiliary device provided by this utility model can directly and quickly detect the meshing clearance of two bevel gears in the finished product state, avoiding the need to disassemble the bevel gear linkage device for detection, thus improving detection efficiency and reducing operational difficulty. Detection in the finished product state is more in line with actual conditions. The output shaft is firmly pressed onto the support column two by the clamping component, ensuring that the output shaft remains in a horizontal state during the detection process, thereby improving detection accuracy. At the same time, the clamping component, in conjunction with the angle gauge, can accurately measure the rotation angle of the input shaft, further improving the accuracy and convenience of detection.

[0006] As a further improvement of the above-mentioned solution of this utility model, a square boss is provided on one end face of the shell; the square boss is supported on the top of the support column, and a positioning block is provided on the top surface of the support column for positioning the square boss.

[0007] As a further improvement to the above-mentioned solution of this utility model, a positioning plane that fits against the end face of the shell is provided on the side of the support column one facing the support column two.

[0008] As a further improvement of the above-mentioned solution of this utility model, the output shaft is supported on the top of the second support column, and the top surface of the second support column is provided with a positioning block two for positioning the output shaft.

[0009] As a further improvement of the above-mentioned solution of this utility model, the clamping component includes a mounting plate and a quick clamp. The mounting plate is mounted on the base, and the quick clamp is located above the second support column and mounted on the mounting plate. The movable end of the quick clamp faces the second support column and is connected to a clamping pad.

[0010] As a further improvement to the above-mentioned solution of this utility model, the clamping pad is made of nylon material.

[0011] As a further improvement of the above-mentioned solution of this utility model, the clamp includes two clamping blocks, which are arranged opposite to each other and each of the two clamping blocks has a semi-circular groove on one side. The two semi-circular grooves are arranged opposite to each other. Two connecting screws are threadedly connected to one of the clamping blocks and the two connecting screws are located on both sides of the semi-circular groove. The two connecting screws are also threadedly connected to the other clamping block. A spring is fitted between the connecting screws and the two clamping blocks, and the two ends of the spring are respectively connected to the two clamping blocks.

[0012] As a further improvement to the above-mentioned solution of this utility model, both clamping blocks are made of plastic.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The bevel gear meshing clearance detection auxiliary device provided by this utility model can directly and quickly detect the meshing clearance of two bevel gears in the finished product state, avoiding the need to disassemble the bevel gear linkage device for detection, thus improving detection efficiency and reducing operational difficulty. Detection in the finished product state is more in line with actual conditions. The output shaft is firmly pressed onto the support column two by the clamping component, ensuring that the output shaft remains in a horizontal state during the detection process, thereby improving detection accuracy. At the same time, the clamping component is used in conjunction with the angle gauge to accurately measure the rotation angle of the input shaft, further improving the accuracy and convenience of detection.

[0016] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0018] This embodiment proposes an auxiliary device for detecting bevel gear meshing clearance, which is used to assist in detecting the bevel gear meshing clearance of the bevel gear linkage device of a new energy cleaning robot. The bevel gear linkage device includes a housing 1, an output shaft 2, an input shaft 3, and two bevel gears 4. The output shaft 2 passes through the housing 1, and a square boss 8 coaxial with the output shaft 2 is provided on one end face of the housing 1. One end of the input shaft 3 extends into the housing 1 and is perpendicular to the output shaft 2. The two bevel gears 4 are both set in the housing 1 and are respectively mounted on two transmission shafts, and the two bevel gears 4 mesh.

[0019] Reference Figure 3 , Figure 4 The auxiliary device for detecting bevel gear meshing clearance proposed in this embodiment includes a base 5, a clamping component, a clamping component, and an angle meter.

[0020] The base 5 provides the mounting foundation for the entire device. Two vertically arranged support columns, 6 and 7, are mounted on the base 5, with their top surfaces forming a support surface. The distance between support columns 6 and 7 must meet testing requirements, ensuring that the square boss 8 of the housing 1 can be supported on the top of support column 6, and that the end of the output shaft 2 furthest from the housing 1 can be supported on the top of support column 7, while maintaining the output shaft 2 in a horizontal position.

[0021] Combination Figure 5 In this embodiment, to better support and position the housing 1, a positioning block 9 for positioning the square boss 8 is provided on the top surface of the support column 1 6. A positioning plane 10 that fits against the end face of the housing 1 is provided on the side of the support column 1 6 facing the support column 2 7. Thus, one side of the square boss 8 fits against the top surface of the support column 1 6, the other side of the square boss 8 fits against the positioning block 9, and the end face of the housing 1 fits against the positioning plane 10. To better position and support the output shaft 2, a positioning block 2 11 for positioning the output shaft 2 is provided on the top surface of the support column 2 7.

[0022] The clamping component includes a mounting plate 12 and a quick clamp 13. The mounting plate 12 is mounted on the base 5, and the quick clamp 13 is located above the second support column 7 and mounted on the mounting plate 12. The movable end of the quick clamp 13 faces the second support column 7, and a clamping pad 14 is connected to the movable end of the quick clamp 13. In this embodiment, the clamping pad 14 is in the form of a screw, which is threadedly connected to the movable end of the quick clamp 13, and is made of nylon. The threaded connection allows for adjustment of the clamping degree.

[0023] Combination Figure 6The clamping component includes two clamping blocks 15, which are arranged opposite each other and each has a semi-circular groove 16 on one side. Two threaded holes are formed through one clamping block 15 on both sides of the semi-circular groove 16, and connecting screws 17 are threaded into each hole. Two threaded countersunk holes are formed on the other clamping block 15, and the two connecting screws 17 are threaded into these holes respectively. The two connecting screws 17 are also threaded into the other clamping block 15. A spring 18 is fitted between the connecting screws 17 and the two clamping blocks 15, with both ends of the spring 18 connected to the two clamping blocks 15 respectively. Connecting the two clamping blocks 15 with the connecting screws 17 facilitates disassembly and allows for clamping of input shafts 3 of different sizes.

[0024] An angle gauge is mounted on a clamping block 15 with a threaded countersunk hole. An angle gauge is a geometric measuring instrument used to measure the tilt angle of an object. When the clamping block is rotated, the angle gauge can measure the angle of rotation of the clamping block.

[0025] In this embodiment, when performing the meshing clearance test on the bevel gear 4, the product to be tested is first arranged as follows: Figure 3 The clamping and fixing process is as follows: The end face of the housing 1 is aligned with the positioning plane 10, so that the square boss 8 is supported on the top surface of the support column 6, and the square boss 8 is pressed tightly against the positioning block 9. The output shaft 2 is supported on the support column 7 and pressed tightly against the positioning block 11. Then, the quick clamp 13 is operated to press the output shaft 2 with the clamping pad 14 (the clamping pad 14 is made of nylon to prevent scratches and damage to the output shaft 2 during testing). Then, the two clamping blocks 15 are placed on the input shaft 3, positioning the input shaft 3 within the two semi-circular grooves 16 (both clamping blocks 15 are made of plastic to prevent scratches and damage to the input shaft 3 during testing). (Scratches and damage), then tighten the two connecting screws 17 to clamp the input shaft 3; then hold the two clamps 15 and gently rotate them clockwise to drive the input shaft 3 to rotate until the two bevel gears 4 stop rotating when they come into contact with each other, and the gap between the two bevel gears 4 is eliminated. Read the angle meter 19 reading at this time; then hold the two clamps 15 and gently rotate them counterclockwise to drive the input shaft 3 to rotate until the two bevel gears 4 stop rotating when they come into contact with each other, and read the angle meter 19 reading at this time. Based on the difference between the two readings of the angle meter 19, the bevel gear meshing clearance is calculated.
