The entire transmission device of the planetary cycloid reducer can be divided into three parts: the input part, the deceleration part, and the output part.
When the input shaft rotates with the eccentric sleeve for one week, due to the characteristics of the tooth profile curve on the cycloid wheel and the limitation of the needle teeth on the needle gear, the motion of the cycloid wheel becomes a plane motion with both revolution and autobiography. When the input shaft rotates for one round, the eccentric sleeve also rotates for one round, and the cycloid wheel rotates one tooth in the opposite direction to obtain deceleration. Then, with the help of the W output mechanism, the low-speed autorotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft. This results in a lower output speed.
Next, let's talk about the installation steps of the cycloid wheel of the cycloid reducer:
First of all, it is necessary to check whether the two cycloids are a pair. The production of cycloids is based on pairs, that is to say, the two pieces of cycloids are not separated during the production process.When installing, the concept of a pair is that the two cycloidal wheels can be completely overlapped.Including the bearing hole, the ten holes (shaft pin hole) and the external tooth shape are safe to overlap at the same time, and they are one piece from the front. If they can overlap, it proves that they are a pair.Note that there are positive and negative cycloids, there are marks on the cycloids, and the marks on each pair of cycloids are also different.
The second step is to rotate one piece of the cycloid wheel 180°, that is, when the intermediate bearing holes are completely coincident, the outer tooth shape is just misaligned, and the position of the tooth heel of the upper piece is exactly the position of the tooth top of the lower piece.Note that the relative position of the two wheels must be remembered, it is best to draw the mark yourself, or remember the position of the original mark on the wheel. (This is a cycloidal wheel with a single tooth difference, and the double tooth difference does not need 180°).
The third step is to put a piece of cycloid wheel into the needle tooth shell, first turn it by hand to see if it is smooth and whether it swings.
The fourth step is to put the eccentric bearing, because the bearing hole of the cycloid pin wheel is equivalent to the outer sleeve of the eccentric bearing, so the correct position of the eccentric bearing is that the bearing hole of the lower cycloid wheel just completely contains the cylindrical ball of the eccentric bearing.Step XNUMX Put in the spacer ring.The sixth step is to put another cycloid wheel, which is the key when putting this wheel.The position should be completely based on the last mark you drew.The seventh step is to put on the shaft sleeve and turn it by hand to see if it can be turned and check whether the installation is correct.
