Description

Technical Field

[0001] The invention relates to the technical field of hypoid gear assembly clearance measuring equipment, and in particular to a hypoid gear assembly clearance measuring tool and a measuring method. Background Art

[0002] When the hypoid gears are meshing, in order to form a lubricating oil film between the meshing tooth profiles and avoid jamming due to friction, heat and expansion of the gear teeth, a gap must be left between the tooth profiles. This gap is called the tooth side clearance. In order to ensure the normal operation of the equipment, the tooth side clearance needs to be within a reasonable range. If the tooth side clearance is too large, meshing impact will occur, resulting in meshing noise of the gears and reducing the product life. If the tooth side clearance is too small, the lubricating oil film cannot be formed, and in severe cases, it will jam. Therefore, inaccurate control of the tooth side clearance seriously affects the product quality, and it needs to be measured and tested. It is very important to choose the appropriate tooth side clearance value.

[0003] Hypoid gears are used for precision transmission, which requires very high gear installation clearance. Only by meeting the assembly accuracy requirements can the rigidity and operating noise of the gear transmission be guaranteed. Hypoid gears have the function of changing the direction of rotational motion by 90°. Compared with other transmission methods with the same function such as turbines, they have the characteristics of small space occupation, high precision and high efficiency. Hypoid gears were commonly used in automotive power transmission in the past, and can also be introduced into the joint shaft transmission of industrial robots. At present, the traditional method is to assemble the hypoid gear components on the arm and wrist housing of the industrial robot to measure the tooth side clearance, which requires repeated disassembly and assembly for measurement, cumbersome operation and low installation efficiency.

[0093] Based on the above scheme, the moving direction of the micro-motion platform 1 3 is the X direction, and the moving direction of the micro-motion platform 2 9 is the Z direction. The specific zero calibration steps in the above S1 are:

[0094] (1) First, use a three-coordinate measuring machine to measure the tolerance of the key installation distance of the tooling and record it, compare it with the theoretical installation distance to calculate the difference, and find the theoretical installation surface;

[0095] (2) Using the adjustment handle 7 of the micro-motion platform 3 in the X direction, the positioning block 4 is driven to move and align with the theoretical installation surface, and the installation zero point position is set to perform zero calibration;

[0096] Then, the positioning block 2 10 is driven by the adjustment handle 2 13 of the micro-motion platform 2 9 in the Z direction to align with the theoretical installation surface, and the installation zero point position is set to perform zero calibration. After this step is done, there is no need to repeat the operation in subsequent assembly, and the installation adjustment value of the input gear assembly 1 and the output gear 2 can be directly measured.

[0097] The measurement process of the present invention is as follows:

[0098] S1: First use a three-coordinate measuring machine to measure the tolerance of the key installation distance of the tooling and record it, compare it with the theoretical installation distance to calculate the difference, and find the theoretical installation surface;

[0099] The positioning block 4 is driven to move and align with the theoretical installation surface through the adjustment handle 7 of the micro-motion platform 3 in the X direction, and the installation zero point position is set to perform zero calibration;

[0100] Then, the positioning block 2 10 is driven to move and align with the theoretical installation surface through the adjustment handle 2 13 of the micro-motion platform 2 9 in the Z direction, and the installation zero point position is set to perform zero calibration;

[0101] S2: Use a measuring tool to measure the height value from the end face of the bearing sleeve of the input gear assembly 1 to the mounting end face of the bearing inner ring, and calculate the difference between the height value and the theoretical mounting distance. The difference is the mounting adjustment value of the input gear assembly 1 in the X direction. According to the mounting adjustment value, the micro-motion platform 13 is moved by any of the above methods to drive the input gear assembly 1 to move to the set position to determine the mounting position of the input gear assembly 1, and the number of gaskets required for the input gear assembly 1 in the X direction is determined according to the mounting adjustment value.

[0102] S3: Place the output gear 2 horizontally on the mounting seat 2 12, which can rotate vertically around its own axis. At the same time, place the input gear assembly 1 on the mounting seat 1 6, and the input gear assembly 1 can rotate horizontally around its own axis and mesh with the output gear 2;

[0103] S4: Manually rotate the input gear assembly 1 and drive the output gear 2 to rotate, measure the tooth side clearance between the two multiple times along the circumference of the input gear assembly 1 and the circumference of the output gear 2 respectively, drive the output gear 2 to move to mesh with the input gear assembly 1 through the measuring mechanism 2 to determine the installation position of the output gear 2 in the vertical direction, record the installation adjustment value of the output gear 2 in the Z direction, and calculate the average value of the tooth side clearance between the input gear assembly 1 and the output gear 2, and determine the number of gaskets required for the output gear 2 in the Z direction based on the average value of the tooth side clearance.

[0104] It should be noted that the above-mentioned tooth side clearance refers to the assembly clearance of the hypoid gear.

[0105] In the actual assembly process, there is no direct measurement method for the installation distance of the hypoid gear, so the assembly clearance of the hypoid gear needs to be measured indirectly using a measuring tool.

[0106] In addition, the hypoid gear assembly clearance measuring tool can also be used to measure the assembly clearance of bevel gears. When the axis of the input gear assembly is orthogonal to the axis of the output gear, it is also applicable to bevel gears.

[0107] The digital micrometer can be used to check the sensitivity of the micrometer handle and is convenient for direct reading during adjustment.

[0108] The advantages of the present invention are:

[0109] 1. The manufacturing process is simple, and the use is simple and quick; it has high precision, high sensitivity, digital display function, fast reading, and can quickly measure the assembly clearance of the gear;

[0110] 2. The digital micrometer can be used to check the sensitivity of the micrometer handle, and it is convenient to read directly when adjusting;

[0111] 3. The whole device assembly has good reading value stability;

[0112] 4. The calculation is not complicated, and the pre-assembly adjustment of gear clearance is realized. The gear assembly parts are tested after the assembly is completed, which greatly reduces the probability of rework and adjustment of unqualified products, saves assembly time and improves assembly efficiency;

[0113] 5. It avoids the accumulation of human errors in the measurement of tooth side clearance, improves the reliability of the tooth side clearance measurement value, and has a reasonable structure, which solves the problem of large error in the detection of hypoid gear tooth side clearance and improves the quality of product assembly.
