Description

Technical Field

[0001] This utility model relates to the field of planetary gear technology, and more specifically, to a planetary gear testing device. Background Technology

[0002] Because the market demand for reducer ratios varies greatly, the factory's approach is to keep the reducer's outer diameter constant, use the same internal teeth Zb, and change the length of the internal teeth to correspond to different reduction stages, thus obtaining different reduction ratios and forming a series of designs. Planetary gears are gear systems that, in addition to rotating around their own axis like fixed-axis gears, also have their axes of rotation rotate around the axes of other gears along with the planet carrier. Rotation around their own axis is called "rotation," and rotation around the axes of other gears is called "revolution," just like planets in the solar system, hence the name. During the production process, planetary gears need to have their meshing accuracy tested by an automatic meshing detection device.

[0003] A search revealed a Chinese patent application with patent number CN202220345046.7, which discloses an automatic planetary gear meshing detection device. The device includes a worktable, a detection structure movably mounted on the top of the worktable, a planetary gear body movably mounted inside the detection structure, and the detection structure including a motor, a threaded rod, a connecting seat, a support rod, a fixing rod, and a fixing plate. The motor is fixedly mounted on the bottom of the worktable.

[0004] The above-mentioned patent has the following shortcomings: 1. When the planetary gears are installed and fixed by the fixing rod and fixing plate, it is not convenient to quickly install the planetary gears, which is not conducive to improving work efficiency and has low practicality; 2. When the two sets of planetary gears are moved together, it is not convenient to detect the meshing degree of the planetary gears with the naked eye, which leads to a reduction in detection efficiency.

[0005] Therefore, there is an urgent need for a planetary gear testing device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the problems that, when planetary gears are installed and fixed using fixing rods and fixing plates, it is not convenient to quickly install the planetary gears, which is not conducive to improving work efficiency and has low practicality; and when two sets of planetary gears are moved together, it is not easy to visually detect the meshing degree of the planetary gears, which leads to reduced detection efficiency.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A planetary gear inspection device is provided to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] A planetary gear testing device includes a testing platform and an observation plate fixedly connected to the top wall of the testing platform. The top wall of the testing platform has a moving groove, and a first moving platform and a second moving platform are slidably connected to the top wall of the testing platform through the moving groove. The top walls of the first moving platform and the second moving platform are rotatably connected to a stabilizing component for placing the gear. The top wall of the second moving platform is slidably connected to an illumination component for testing the gear meshing degree.

[0011] As a preferred technical solution of this application, the stabilizing component includes a rotating shaft rotatably connected to the top wall of the first moving platform, a placement ring fixedly connected to the outer wall of the rotating shaft, a limit ring slidably connected to the inner wall of the rotating shaft, and a tension spring fixedly connected to the inner wall of the rotating shaft. The end of the tension spring away from the rotating shaft is also fixedly connected to the limit ring.

[0012] As a preferred technical solution of this application, the top wall of the limiting ring is rotatably connected to an adjusting ring, the top wall of the limiting ring is fixedly connected to a uniformly distributed fixing plate, the inner wall of the fixing plate is slidably connected to a telescopic rod, the top wall of the telescopic rod is fixedly connected to a sliding shaft, the inner wall of the adjusting ring is provided with a uniformly distributed adjusting groove, the sliding shaft is slidably connected to the inner wall of the adjusting groove, the top wall of the adjusting ring is provided with a fixing groove, and the top wall of the limiting ring is threadedly connected to a fixing bolt, the fixing bolt cooperating with the adjusting ring through the fixing groove.

[0013] As a preferred technical solution of this application, a drive motor is fixedly connected to the inner wall of the first moving stage, a first gear is rotatably connected to the inner wall of the first moving stage, the output end of the drive motor is fixedly connected to the first gear, a second gear is rotatably connected to the inner wall of the first moving stage, a connecting rod is fixedly connected to the top wall of the second gear, and one end of the connecting rod passing through the first moving stage is also fixedly connected to the rotating shaft.

[0015] In the scheme of this application:

[0016] 1. By rotating the adjusting ring and adjusting the groove, the telescopic rod is moved out of the fixed plate through the sliding shaft. At the same time, the tension spring pulls the limiting ring to press the telescopic rod tightly against the top of the planetary gear, thereby realizing the quick installation of the planetary gear and improving the convenience of installation. This solves the problem in the existing technology that when the planetary gear is installed and fixed by the fixed rod and the fixed plate, it is not easy to quickly install the planetary gear, which is not conducive to improving work efficiency and has low practicality.

[0017] 2. By adjusting the lighting plate to the middle position of the two sets of planetary gears through the sliding push frame, and then observing the light passing through the planetary gears through the observation plate, the convenience of observing the meshing degree of the planetary gears is improved. This solves the problem in the prior art that when the two sets of planetary gears are moved together, it is not easy to detect the meshing degree of the planetary gears with the naked eye, which leads to a decrease in detection efficiency.

By setting the first moving platform 103 and the second moving platform 104, it is convenient to adjust the position of the planetary gear, thereby improving the ease of use.

[0026] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, the stabilizing component further includes a rotating shaft 110 rotatably connected to the top wall of the first moving platform 103.

By setting the tension spring 113, it is easy to pull the limiting ring 112 to fit tightly against the planetary gear, thereby improving the stability of the planetary gear installation.

[0027] like Figure 1-4 As shown, in a preferred embodiment, based on the above method, further, the top wall of the limiting ring 112 is rotatably connected to an adjusting ring 114, the top wall of the limiting ring 112 is fixedly connected to a uniformly distributed fixing plate 115, the inner wall of the fixing plate 115 is slidably connected to a telescopic rod 116, the top wall of the telescopic rod 116 is fixedly connected to a sliding shaft 117, the inner wall of the adjusting ring 114 is provided with a uniformly distributed adjusting groove 118, the sliding shaft 117 is slidably connected to the inner wall of the adjusting groove 118, the top wall of the adjusting ring 114 is provided with a fixing groove 119, and the top wall of the limiting ring 112 is threadedly connected to a fixing bolt 124.

By setting the telescopic rod 116, the extension length of the telescopic rod 116 can be adjusted according to the size of the planetary gear, making it more versatile.

[0028] like Figure 1-2As shown, in a preferred embodiment, based on the above method, a drive motor 120 is fixedly connected to the inner wall of the first moving stage 103, a first gear 121 is rotatably connected to the inner wall of the first moving stage 103, the output end of the drive motor 120 is fixedly connected to the first gear 121, a second gear 122 is rotatably connected to the inner wall of the first moving stage 103, a connecting rod 123 is fixedly connected to the top wall of the second gear 122, and one end of the connecting rod 123 passing through the first moving stage 103 is also fixedly connected to the rotating shaft 110.

[0030] Specifically, in use, this planetary gear testing device works as follows: First, the planetary gear to be tested is placed on the placement ring 111 via the rotating shaft 110. Then, by pulling the limiting ring 112 upward, the fixing plate 115 on the limiting ring 112 is pulled to the top of the planetary gear. Then, the adjusting ring 114 is rotated, and under the action of the adjusting groove 118, the telescopic rod 116 is driven to extend out of the fixing plate 115 via the sliding shaft 117, thereby fixing the top of the planetary gear through the telescopic rod 116. Then, the fixing bolt 124 is screwed into the limiting ring 112, and the adjusting ring 114 is fixed through the fixing bolt 124. Under the action of the tension spring 113, the telescopic rod 116 is pulled to fit tightly against the planetary gear, thus achieving convenient installation of the planetary gear. Then, the device is started. The bidirectional screw simultaneously drives the first moving platform 103 and the second moving platform 104 on both sides to move towards the middle, meshing the planetary gears on the first moving platform 103 and the second moving platform 104 together. Then, the drive motor 120 is started to drive the first gear 121 to rotate, which in turn drives the second gear 122 to rotate. The connecting rod 123 drives the rotating shaft 110 on the top of the first moving platform 103 to rotate, thereby driving the planetary gears to rotate. Then, the sliding push frame 131 adjusts the lighting plate 132 to the position where the two sets of planetary gears are meshed. By observing the light passing through the planetary gears on the observation plate 101, the degree of meshing of the planetary gears can be observed, thereby improving work efficiency.
