The advantages and disadvantages of X cycloid reducers and B cycloid reducers are similar, as follows:
advantage :
Large reduction ratio : Single-stage transmission can achieve a reduction ratio of 1:87. If multi-stage transmission is used, the reduction ratio is larger and can meet the transmission needs of various large reduction ratios.
High transmission efficiency : needle teeth meshing sleeve-type rolling friction, no relative sliding of the meshing surface, and the first-stage deceleration efficiency can reach more than 90%.
Compact structure : adopts the planetary transmission principle, the input shaft and the output shaft are on the same axis line. Compared with other reducers of the same power, the volume and weight can be reduced by more than 1/3, making it easy to install and arrange, and is suitable for space-constrained occasions.
Stable operation and low noise : the cycloid needle teeth have a large number of meshing teeth and a large overlap coefficient, which can effectively reduce vibration and noise, and is suitable for environments with high noise requirements.
Long service life : The main parts are made of high-carbon chromium steel, which can obtain high strength after quenching, and some transmission contacts adopt rolling friction, which has little wear and durability.
High transmission accuracy : The number of meshing teeth of the cycloid pin wheel transmission is large, the average error effect is significant, which can effectively improve the transmission accuracy and is suitable for equipment and occasions with high requirements for transmission accuracy.
Strong overload capacity : Due to the large number of teeth meshing at the same time, it has a large overload capacity and strong impact performance, and can withstand a certain degree of overload and impact load.
shortcoming :
The manufacturing process is complex : the manufacturing accuracy of main parts such as cycloid wheels, needle pins, needle sleeves, etc. is high, the processing is difficult, and the cost is relatively high.
The bearings of the rotary arm are prone to damage : the bearings of the rotary arm are subject to a large force and the speed is slightly higher than the high-speed shaft. It is a weak link in the reducer, which limits the speed and transmission power of the high-speed shaft, and is prone to damage, affecting the normal operation of the reducer.
Maintenance is difficult : the internal structure is relatively complex, requires professional technicians to maintain and repair, the maintenance cost is high, and the disassembly and assembly process is relatively cumbersome.
