(Summary description)The planetary gear motor has high torque and impact resistance; while traditional gears are driven by only a few contact surfaces between the two gears, all loads are concentrated on the few gear surfaces in contact, which is prone to friction and breakage between the gears. The planetary gear has a large area and a 360-degree uniform load on the contact surface of the gear. Multiple gear surfaces jointly bear the impact load evenly, and can withstand higher torque and impact.

1. The planetary gear motor has high torque and impact resistance; while traditional gears only rely on a very small number of contact surfaces between the two gears to squeeze and drive, all loads are concentrated on the few gear surfaces in contact, which is prone to friction and breakage between the gears . The planetary gear has a large area and a 360-degree uniform load on the contact surface of the gear. Multiple gear surfaces jointly bear the impact load evenly, and can withstand higher torque and impact.
2. The planetary gear motor is small in size and light in weight; the traditional gear design has multiple groups of large and small gears biased towards staggered transmission and deceleration. Since the reduction ratio needs to be generated by a multiple of the number of two gears, there must be a certain spacing between the large and small gears. The gear box has a huge accommodation space, especially when the high-speed ratio is combined, more than two reduction gear boxes need to be connected and combined, the structural strength will be relatively weakened, and the length of the gear box will be lengthened, resulting in a relatively large volume and weight. The structure of the planetary gear can be repeatedly connected according to the required number of segments, and the multi-segment combination can be completed separately.It is small in size, light in weight, light in appearance, and more valuable.
3. The planetary gear motor has high efficiency and low backlash; since each group of gears of the ordinary gear reducer has only a single tooth surface occlusal contact, when the transmission is equal to the torque, it requires greater tooth surface stress, so the gear design must be used. The larger the module and the thickness, the larger the gear module, the larger the gear clearance tolerance value will be, and the higher gear clearance will be formed, and the cumulative backlash between the reduction ratios of each stage will increase accordingly. The unique multi-point uniform close contact in the planetary gear combination, and the arc-enclosed structure of the outer gear ring. The outer gear ring and the planetary gear are tightly combined, and the tightness between the gears is high. In addition to improving the extremely high efficiency of the reducer, the design itself can achieve high-precision positioning.
