The additional basis for selecting the servo planetary reducer is the radial load and the axial load on the extended end of the output shaft.The strength of the shaft and the bearing capacity of the bearing determine the allowable radial load of the shaft extension.

　　The allowable value given in the product catalog refers to the force acting on the midpoint of the shaft extension in an unfavorable direction.When the acting force is not at the midpoint, the closer to the shaft shoulder, the greater the allowable radial load; on the contrary, the farther the acting point is from the shaft shoulder, the smaller the allowable radial load.

　　What aspects need to be considered when choosing a servo planetary reducer

　　When selecting the servo right-angle planetary reducer, pay attention to the quality of the input shaft.

　　The input shaft is divided into an integral input shaft and a split input shaft.The one-piece structure eliminates the error of connecting the input shaft and the sun gear, making it more accurate, more concentric, with greater torque, and more stable transmission.

　　When choosing a planetary reducer, pay attention to the quality of the ring gear

　　The inner gear ring of the planetary reducer is inserted on the box body, the material used is alloy steel 42Crmo, and the process is quenched and tempered and nitrided by imported gear shaper to ensure its accuracy and hardness.

　　It adopts a split structure, and most of the inner gear ring adopts pull teeth, and the gear ring is inserted into the box body.Some manufacturers also use shapers, but most of their materials use 45 steel, and the materials do not do any treatment.

　　When choosing a planetary reducer, pay attention to the quality of the double arm

　　The double-rotating arm means that the planet carrier gear is supported on both sides. When the output shaft is driven with load, the gear will not deviate in the opposite direction, and there is a high-speed bearing at the connection between the planet carrier and the input shaft to make the gear transmission more stable.
