[0002] Planetary gears refer to gear systems that, in addition to being able to rotate around their own rotation axes like fixed-axis gears, also have rotation axes that rotate around the axes of other gears along with the planetary carrier. The rotation around their own axes is called "rotation", and the rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name. Simple (single-row) planetary gear mechanisms are the basis of speed change mechanisms. Usually, the speed change mechanisms of automatic transmissions are composed of two or more rows of planetary gear mechanisms. Simple planetary gear mechanisms include a sun gear, several planetary gears and a gear ring, in which the planetary gears are supported by the fixed axis of the planetary carrier, allowing the planetary gears to rotate on the supporting axis; the gear ring, as an important component of the planetary gear, needs to have its internal teeth processed after processing.

[0036] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0037] Step 1: Start the servo motor 66. After the servo motor 66 is started, it can drive the turntable 67 to rotate clockwise, so that the arc hole 69 rotates in a circle around the center point of the turntable 67, so that the inner wall of the arc hole 69 pushes the push column 68 upward, so that the four plug columns 61 can drive the clamping rod 62 to move smoothly outward under the restriction of the slide groove 64 and the slider 63, so that the clamping rods 62 around the periphery move outward until the gear ring can be put into the inner side of the clamping rod 62, and the gear ring is tightly attached to one side of the clamping block 610, and the turntable 67 is driven to rotate counterclockwise to drive the push column 68 to move inward, so that the clamping rod 62 can be driven to move inward to clamp the turntable 67 to limit the gear ring; Step 2: Turn the bolt 613 so that the bolt 613 pushes the limit plate 611 to move toward one side of the rectangular hole 612 under the action of the rotational force of the outer wall thread, so that the limit plate 611 clamps the gear ring on one side of the clamping block 610 to prevent the gear ring from moving; Step 3: Start the hydraulic cylinder 72, which can push the support plate 73 to move upward, so that under the restriction of the guide rod 74, the guide rod 74 pushes the housing 75 to move upward, so as to adjust the height of the grinding wheel 711, adjust the bottom end of the grinding wheel 711 to the position corresponding to the inner teeth of the gear ring, and start the motor 710 to drive the grinding wheel 711 to rotate; Step 4: Start the reduction motor 712 to drive the rotating handle 713 to rotate, so that one end of the rotating handle 713 drives one end of the connecting rod 714 to rotate in a circle, so that the other end of the connecting rod 714 can pull the sliding column 716 to move back and forth left and right under the restriction of the limit rod 715, so that the connecting block 76 moves in the through hole 77 to drive the first mounting plate 78 to move back and forth left and right. When the first mounting plate 78 drives the second mounting plate 79 to move to one side, the grinding wheel 711 contacts and grinds the inner teeth of the gear ring to grind its surface. By starting the stepping motor 4 to control the cylindrical disk 5 to rotate a certain angle, the grinding wheel 711 can continuously grind the teeth at different positions of the gear ring when it moves back and forth. The processing efficiency is high, and the mechanical grinding can ensure a certain grinding accuracy, improve the processing quality of the product, reduce the difficulty of operation, and is conducive to wide promotion.
