China 12V gear motor factory, the installation and layout of the deceleration motor is characterized by high efficiency and reliability, long service life, easy maintenance, wide application and so on. Its series can be divided into single-stage, two-stage and three-stage gear reduction motor, installation and layout of the main expansion, coaxial and shunt type.
1, two stage cylindrical deceleration motor expansion, gear relative to the position of the support is asymmetric, when the shaft produces bending and torsion deformation, load in the tooth width distribution is not uniform, so the shaft should be designed with greater stiffness, and make the gear away from the input or output end.
2, the characteristics of the distribution type of two-stage cylindrical gear motor, shunt type of overhanging deceleration motor shaft position by either side, convenient for the machine's overall configuration, shunt level are done helical gear, right-handed and left-handed, to offset the axial force, should be one of the shaft axial winding, can do a bit to avoid stuck gear.
3, the characteristics of coaxial reduction motor: radial size compact, but the axial size is large. Due to the large middle shaft, the axle has a large perturbation under load, so the load concentration along the tooth width is serious. At the same time, because the center of the two gears must be consistent, it is difficult to make full use of the bearing capacity of the gear, and the bearing lubrication in the middle part of the deceleration is also difficult. The input and output of the deceleration motor are located at both ends of the same axis, which brings restrictions to the overall configuration of the transmission device.
