Installation of cycloid gear in cycloid pin gear reducer

All transmission devices of cycloidal pinwheel reducer can be divided into three parts: input part, deceleration part and output part.
The input shaft rotates with the eccentric sleeve for one cycle. Due to the characteristics of the tooth profile curve on the cycloid gear and the limitation of the needle teeth on the needle gear, the motion of the cycloid gear becomes a plane motion with both revolution and self rotation. When the input shaft rotates forward for one cycle, the eccentric sleeve also rotates for one cycle. The cycloid gear rotates through a tooth in the opposite direction to obtain deceleration, and then with the help of the W output mechanism, The low-speed rotation motion of the cycloid wheel is transmitted to the output shaft through the pin shaft, so as to obtain a lower output speed.
Installation steps of cycloidal pinwheel reducer:
Check whether the two cycloidal wheels are a pair. The cycloidal wheel is made in pairs, that is, the two pieces of cycloidal wheel are not separated in the production process. During installation, the concept of a pair is that the two cycloidal wheels can completely coincide. Including bearing holes, ten holes (shaft pin holes) and external tooth shapes are safely overlapped at the same time. From the front, it is one piece. If they can be overlapped, it is proved that they are a pair, but they cannot be overlapped, and it is proved that they are not a pair and cannot be used. Note that the cycloidal wheels have positive and negative marks, and the marks of each pair of cycloidal wheels are also different.
The second step is to rotate one piece of the cycloid wheel by 180 °, that is, when the middle bearing holes completely coincide, the outer tooth profile is just misaligned, and the tooth heel position of the upper piece is just the tooth top position of the lower piece. Note that the relative position of the two wheels must be remembered, * * * draw a mark by yourself, or remember the position of the original mark on the wheel. (this is a cycloid wheel with single tooth difference, and 180 ° is not used for double tooth difference).
The third step is to put a piece of cycloid wheel into the needle tooth shell and rotate it by hand to see whether it is smooth and swinging.
The fourth step is to put in the eccentric bearing. Because the bearing hole of the cycloid needle wheel reducer is equivalent to the outer sleeve of the eccentric bearing, 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 5 put in the spacer ring.
The sixth step is to put another cycloid wheel, which is the key. The position shall be placed completely according to the mark drawn after * * *.
Step 7 put on the shaft sleeve and rotate it by hand to see if it can rotate and check whether the installation is correct.
