Features geared motors are high efficiency and reliability, long life, easy maintenance, widely used and so on. Its progression can be divided into single-stage, two and three gear motors, installation layout mainly expansion, coaxial and Split.
1, the two-stage expansion inside the cylindrical gear motor, gear position relative to the support asymmetry, when the shaft bending and torsion deformation generated, the uneven distribution of the load in the tooth width, and therefore should be designed with a large shaft stiffness, and the gear away from the input or output.
2, two hypoid gearbox Split features: external shunt geared motor shaft extension position may extend on either side, to facilitate the overall configuration of the machine, split level have Pc Helical Gear Box are made, while the right hand, while the left-handed to counteract the axial force, should make them do a little bit of a shaft axial swimming, so as not to get stuck gear.
3 features Helical geared motors: radial compact size, but larger axial dimension. Since the intermediate shaft is large, larger axis of flexing when under load, thus along the tooth width load on centralized phenomenon is more serious. And because the center of a two-stage gear must be consistent, so tell the carrying capacity level is difficult to make full use of the gear, and is located in the middle part of the deceleration bearing lubrication is also more difficult. The input and output of geared motors are located at both ends of the same axis, the overall configuration of the actuator to bring restrictions
