Description

Technical Field

[0001] The utility model belongs to the field of gear circular runout, and in particular relates to a gear circular runout detection device. Background Art

[0002] In the modern machinery industry, gears are key components widely used in transmission systems, and their performance quality directly affects the operating stability and efficiency of the mechanical system. The circular runout of gears is an important quality parameter in gear manufacturing, which refers to the irregular fluctuations of the gear tooth surface during movement, which may cause vibration, noise and life problems in the transmission system.

[0003] Traditional gear circular runout detection methods usually use precision instruments to measure the circular runout of gears, such as a three-coordinate measuring machine. The detection efficiency of a three-coordinate measuring machine is relatively low, and the requirements for the detector are relatively high, and professional training is required. In view of this, it is necessary to design a method that can quickly detect the circular runout of gears. Utility Model Content

[0004] In order to solve one or more of the above-mentioned defects in the prior art, the utility model provides a gear circular runout detection device, which has a simple structure and can amplify the circular runout of the gear and detect it through a dial indicator.

[0005] In order to achieve the above object, the utility model provides a gear circle runout detection device, comprising:

[0006] a mounting plate;

[0007] A positioning seat, the positioning seat comprising a first seat body and a second seat body, the first seat body is connected to a first top, and the second seat body is connected to a second top;

[0008] A lever assembly, the lever assembly comprising an articulated seat, a lever rotatably connected to the articulated seat, the lever having a long arm and a short arm, the short arm being located between the first top and the second top;

[0009] A dial gauge assembly comprises a connecting seat, on which a dial gauge is connected, and a dial gauge head corresponds to a long arm of the lever.

[0010] Furthermore, the first top is movably connected to the first base, the second top is movably connected to the second base, and the first base and the second base are both connected with screws.

[0011] Furthermore, the connecting seat is a Z-shaped connecting seat, and the dial indicator is connected to the upper horizontal plate of the Z-shaped connecting seat.

[0012] Furthermore, the first seat body and the second seat body are connected via a bottom plate, long slots are formed on both sides of the bottom plate, and the bottom plate is movably connected to the mounting plate via the long slots.

[0013] Furthermore, the length ratio between the short arm and the long arm is 1:5.

[0014] The beneficial effects of the utility model are:

[0016] Second, the dial indicator assembly is connected to the connection seat, and the dial head corresponds to the long arm of the lever. This design allows the detection results of the device to be presented through intuitive dial indicator readings, which not only facilitates real-time monitoring by operators, but also provides data that is easy to record and analyze, helping to more comprehensively understand the circular runout of the gear;

[0017] Third, the design of the hinged seat and the long and short arms of the lever assembly allows the circular runout of the gear to be magnified in a certain proportion when it rotates, so that it can be accurately captured by the dial indicator. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] See also Figures 1 to 3 A gear circle runout detection device shown includes:

[0024] A mounting plate 1;

[0025] A positioning seat 2, the positioning seat 2 comprises a first seat body 3 and a second seat body 4, the first seat body 3 is connected to a first top 5, the second seat body 4 is connected to a second top 6;

[0026] A lever 8 assembly, the lever 8 assembly includes an articulated seat 7, a lever 8 is rotatably connected to the articulated seat 7, the lever 8 has a long arm 9 and a short arm 10, and the short arm 10 is located between the first top 5 and the second top 6;

[0027] The dial gauge 12 assembly comprises a connecting seat 11 , to which the dial gauge 12 is connected, and the gauge head of the dial gauge 12 corresponds to the long arm 9 of the lever 8 .

[0028] The process of the utility model when in use is as follows: first, the standard gear is adjusted, and the standard gear is connected between the first seat body 3 and the second seat body 4 of the positioning seat 2 through the center holes at both ends of its connecting shaft. Specifically, the first top 5 and the second top 6 are matched with the center holes at both ends of the gear connecting shaft respectively, and at the same time, the tooth surface of the gear is in contact with the upper surface of the short arm 10 of the lever 8. At the same time, the position of the dial indicator 12 is corrected. Subsequently, the standard gear is removed, and the gear to be tested is connected between the first seat body 3 and the second seat body 4. The gear to be tested is rotated. When the gear rotates, it will contact the short arm 10 of the lever 8. The short arm 10 is squeezed by the gear tooth surface and will move up and down. Through the principle of the lever 8, the up and down movement of the short arm 10 will be transmitted to the long arm 9, so that the upper surface of the end of the long arm 9 will move more obviously. At this time, the dial indicator 12 can accurately capture this movement and display it through the dial. At this time, observe the movement of the dial pointer to observe whether it is within the error range. If it is within the error range, it means that the circular runout of the gear is qualified.

[0029] Further, the first apex 5 is movably connected to the first base body 3, the second apex 6 is movably connected to the second base body 4, and the first base body 3 and the second base body 4 are both connected with screws 13. Specifically, the first apex 5 of the utility model is movably connected to the first base body 3, and the second apex 6 is movably connected to the second base body 4, so that the distance between the first apex 5 and the second apex 6 can be adjusted according to different gears. When the gear positioning is completed, the first apex 5 and the second apex 6 are positioned by the screws 13, and the gear can be detected.

[0030] Further, the connecting seat 11 is a Z-shaped seat 14, and the dial indicator 12 is connected to the upper horizontal plate 15 of the Z-shaped seat 14. Specifically, the connecting seat 11 of the utility model is a Z-shaped seat 14, so that the upper horizontal plate 15 can be connected to the dial indicator 12, and the dial indicator 12 head can also pass through the upper horizontal plate 15 and the long arm 9 of the lever 8 to correspond.

[0031] Furthermore, the first seat body 3 and the second seat body 4 are connected via a bottom plate 16, and long slots 17 are provided on both sides of the bottom plate 16, and the bottom plate 16 is movably connected to the mounting plate 1 via the long slots 17. Specifically, the first seat body 3 and the second seat body 4 of the utility model are connected via the bottom plate 16, and at the same time, the long slots 17 on the bottom plate 16 can adjust the position of the positioning seat 2, so as to be suitable for the detection of different gears.

[0032] Furthermore, the length ratio between the short arm 10 and the long arm 9 is 1:5. By setting the length ratio between the short arm 10 and the long arm 9 to 1:5, the up and down movement of the short arm 10 will be magnified five times, so that it can be accurately captured by the dial indicator 12.
