The present invention relates to a motor, comprising: a motor housing, a cavity being formed inside the motor housing, a stator assembly and a rotor assembly being accommodated in the cavity, two ends of the motor housing being provided with an opening; an end cover, the end cover being arranged at one side of the motor housing and used for sealing the opening at said side; a flange portion, the flange portion sealing the opening at the other side of the motor housing; the rotor assembly is provided with a rotor shaft, one end of the rotor shaft passing through the end cover, the other end passing through the flange portion; a magnetic ring, the magnetic ring being arranged on the rotor shaft and located at the side of the end cover away from the motor housing; output teeth, the output teeth being arranged on the rotor shaft and located at the side of the flange portion away from the motor housing. The present invention reduces rotor gear parts, connects the motor and a gear box by means of the flange portion, decreases the length size, increases the degree of concentricity of the motor and the gear box, improves driver installation efficiency, and saves installation costs.

Motor and driver including motor

A transmission gear box includes a cylindrical box body defining a cavity for gears and an end cover fixed on at least one axially opened end of the cavity of the box body. A fitting structure includes an inner fitting surface located on a surface of one of the box body and the end cover and an outer fitting surface located on a surface of the other one of the box body and the end cover. The inner fitting surface and the outer fitting surface are fixed to each other. A clearance fit area with interference fit areas located on both sides thereof is arranged between the inner fitting surface and the outer fitting surface such that during welding of the inner fitting surface to the outer fitting surface, a molten body produced by melting of the interference fit areas flows to the clearance fit area.

Transmission gear box

Disclosed is a planetary gear transmission box, comprising a housing portion, a first planetary gear transmission stage, and a second planetary gear transmission stage, wherein the first planetary gear transmission stage comprises a first sun gear (), a first planetary carrier (), and a first ring gear; the second planetary gear transmission stage comprises a second sun gear, a second planetary carrier (), and a second ring gear (); the first sun gear () is connected to an external input element; the first planetary carrier () is connected to the second sun gear; the second planetary carrier () is connected to an output element; the transmission ratio of the gear transmission box is greater than 25; and the second planetary carrier () is directly supported on the housing portion. The locked rotor torque of the gear box is increased, such that the output rotational speed is reduced, and thus a bearing member at the output end can be omitted.

Planetary gear transmission box

The present application relates to a planet carrier assembly for a vehicle door closing actuator. The planet carrier assembly comprises a plurality of planetary gears and a planet carrier body. The planet carrier body comprises a disc portion, a cover portion and an output shaft portion, wherein the plurality of planetary gears are rotatably mounted on the disc portion via a corresponding number of mounting shafts fixed to the disc portion, one end of the mounting shaft protruding from a central hole of the planetary gear is pressed into a corresponding receiving hole on the cover portion, and the planet carrier body is further provided with a rotation locking device to prevent the cover portion from rotating circumferentially relative to the disc portion. The planet carrier assembly according to the present application has the advantages such as low cost, high strength, and simple assembly.
