Shafting structure, double-shaft motor, fan and household appliance

Abstract

The invention provides a shafting structure, a double-shaft motor, a fan and a household appliance. The shafting structure comprises a first rotating shaft, a second rotating shaft and a bearing assembly, wherein the second rotating shaft is hollow and sleeves the periphery of the first rotating shaft, the front end of the first rotating shaft extends out of the front end of the second rotating shaft, and the rear end of the first rotating shaft is located behind the rear end of the second rotating shaft; and the bearing assembly comprises a first bearing, a second bearing and a third bearing, the first bearing sleeves the periphery of the first rotating shaft, the second rotating shaft sleeves the periphery of the second rotating shaft, and the third bearing is arranged at the front end of the second bearing and located between the first rotating shaft and the second rotating shaft. The shafting structure has the remarkable advantages of being compact in structure, high in practical functionality, stable in supporting, convenient to install, small in axial size, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a shaft system structure, a double-shaft motor, a fan and household appliances. Background technique [0002] With the continuous improvement of the quality of life requirements, the motor is also put forward higher requirements, such as having two coaxial and same side independent output capabilities, smaller size, and lower cost. At present, the common motors on the market still have one output shaft, dual shafts with output at both ends at the same speed, and dual shafts with output at the same end. It is only the shaft output on the side. The shaft system support method adopted by the dual-axis motor output at the same end is still supported by two bearings for each shaft. This support method requires a large axial space and relatively poor support stability. Contents of the invention [0003] The invention proposes a shafting structure, aiming at reducing the volume of the...

Problems solved by technology

At present, the common motors on the market still have one output shaft, dual shafts with output at both ends at the same speed, and dual shafts with output at the same end. The side output shaft is only the shaft system support method adopted by the dual-axis motor output at the same end, or two bearings are used for each shaft. This support method requires a large axial space and relatively poor support stability.
