Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a hub-type speed-regulating motor for a clothes dryer. Background Technology

[0002] The speed-regulating motor in a hub-type dryer is the core component that drives the drum's rotation and adjusts its speed. Its design must balance drying efficiency, garment protection, and energy consumption control. The hub-type structure directly connects the motor's rotor to the dryer's drum hub, eliminating traditional belts and gears, resulting in a more compact structure and higher transmission efficiency. Furthermore, combined with advanced speed control technologies such as frequency converters, it enables precise control of the motor's speed, meeting the different speed requirements of various garments during the drying process, thus improving drying effectiveness and garment protection.

[0003] Existing motors typically use fixed-frequency motors with a fixed speed, making it difficult to precisely adjust them according to different clothing materials and drying needs. This results in problems such as low drying efficiency and easy damage to clothing. When drying a large number of clothes or heavy clothes, the motor may not be able to achieve the ideal speed and drying effect, thus prolonging the drying time.

[0004] A search revealed that Chinese patent application CN201020179242.9 discloses a pulley for an electric motor and its application in a clothes dryer motor; it includes a hub and an oil-impregnated bearing, the oil-impregnated bearing being installed in a through hole in the center of the hub; the hub includes an outer wheel body, an inner wheel body, and several spokes connecting the outer wheel body and the inner wheel body, the spokes being straight sheet-like bodies; each of the two outer edges of the outer wheel body is provided with an outwardly extending annular baffle, thereby forming an annular groove on the outer edge of the outer wheel body and between the two annular baffles; the annular baffles and the hub are integrally injection molded;

[0005] The motor in the aforementioned patent requires a belt to effectively transmit its output during operation. This may result in insufficient power when used in large dryers or applications requiring high-power drive. This could lead to the motor failing to reach the desired speed and drying effect when drying large quantities or heavy clothing, prolonging drying time. Furthermore, the belt will wear down over time, increasing maintenance costs. Additionally, slippage and freewheeling between the belt and pulleys during power transmission can compromise work efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a hub-type speed-regulating motor for a clothes dryer. In this device, a driving gear fixedly installed at one end of the rotating shaft meshes internally with multiple driven gears, enabling the multiple driven gears to rotate along the cavity inside the mounting housing. During rotation, the external teeth of the driven gears mesh with the teeth in the cavity, thereby effectively realizing the rotation of the hub within the mounting housing. This ensures the synchronous rotation of the hub and the rotating shaft during power transmission, thus effectively guaranteeing the motor's performance and efficiency, and increasing the motor's service life; thereby solving the problems mentioned in the background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A hub-type speed-regulating motor for a clothes dryer includes a stator; symmetrical fixed housings are respectively fixed to both ends of the stator by bolts; a rotating shaft is nested inside the stator; the rotating shaft is movably mounted to the fixed housings via bearings;

[0009] The rotating shaft extends to the outside of the fixed housing and is fixedly mounted with a drive gear.

[0010] As a further technical solution of this utility model, the driving gear and the side wall of the fixed shell are provided with a support frame; the support frame is installed with a rotating shaft through a bearing; the support frame is provided with three equally spaced support plates, and a driven gear is movably installed on one side of the support plate.

[0011] As a further technical solution of this utility model, the inner sides of all three driven gears are meshed with the driving gear.

[0012] As a further technical solution of this utility model, the driving gear, driven gear and support frame are all movably installed in the mounting housing, wherein the inner side wall of the mounting housing is provided with annular teeth; these teeth mesh with the outer edges of the three driven gears.

[0013] As a further technical solution of this utility model, the mounting shell is fixedly installed at the center of the hub and is coaxially arranged with the stator;

[0014] As a further technical solution of this utility model, the side of the fixed shell away from the wheel hub is fixedly installed with the frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this utility model, when in use, the two ends of the stator are fixed to the fixed shell with bolts, and the fixed shell is used to fix the stator to the frame. Then, the rotor drives the rotation of the shaft to transmit power to the hub.

[0017] In this utility model, during power transmission, the driving gear at the end of the shaft meshes with multiple driven gears simultaneously. The multiple driven gears are installed in conjunction with the support frame to achieve synchronous rotation. During the rotation of the driven gears, the outer surface of the driven gears meshes with the teeth provided in the cavity of the mounting shell, thereby effectively achieving the effect of the shaft driving the hub to rotate.

[0018] This invention, during operation, effectively reduces the power transmission distance by meshing the driving gear and the driven gear, and by meshing the driven gear with the teeth inside the mounting housing. This ensures the synchronous rotation between the shaft and the hub, thereby effectively guaranteeing the performance and efficiency of the motor and extending its service life.
