Transmission Sealer most commonly used is the planetary gear drive, use that drive, what unique characteristic?
Compared with the fixed planetary gear mechanism gear mechanism, it has the following characteristics:
1, the planetary gear mechanism, small size, light weight. Reducer planetary gear mechanism made compared with the conventional cylindrical gear reducer, the volume can be reduced to one-half of one quarter.
2, the planetary gear mechanism load capacity, smooth operation, speed ratio.
3, the planetary gear reducer mechanism made of the efficiency of 98% to 99%.
4, the planetary gear mechanism complicated structure, high machining accuracy.
5, can achieve a differential gear.
    
    Since the planetary gear mechanism with these characteristics, with the constant improvement, application processing and measuring technology gear planetary gear mechanism of the rapid expansion in automated production equipment has been widely used.
   
Press the number of the center wheel Category:
    If the number K represents the center wheel by using H represents the transfer arm, with the rotation of the spindle member V represents around, press the center of the wheel planetary gear mechanism can be divided into 2K-H planetary gear mechanism, 3K planetary gear mechanism and the planetary gear KHV 3 class institution.
    
Automatic classification by activity degrees:
    In the planetary gear mechanism, wherein the degree of freedom of a mechanism known as a planetary gear mechanism, and two or more degrees of freedom differential mechanism called a planetary gear mechanism. Such institutions in the automated equipment used to do differential.

    Planetary gear ratio calculated as follows:
    Due to the rotational movement of the planetary gear mechanism is complicated, and therefore can not use the fixed axis transmission gear mechanism to calculate the ratio calculation. There are two methods to calculate the planetary gear mechanism transmission ratio, it was transformed institution and the basic method of calculation. Commonly used for the conversion Institutions Act apply it "absolute motion of a body does not affect the overall relative movement between the various components of the internal mechanism," the basic principle in the calculation of the drive, the first planetary gear set is converted to shaft drive. Planetary gear

    Application conversion mechanism calculated ratios should pay attention: the conversion mechanism meshing each gear ratio between the sign, external gear when the positive and negative, when the ring.
    To simplify the calculation of the original speed, preferably fixed on the center of the wheel speed denominator. In general planetary gear mechanism, there is a rack-mounted wheel center, their original speed should be zero.
