Abstract

The invention provides a driving device, which includes a motor and a gearbox assembly. The motor includes a rotor and a stator. The rotor has a rotating shaft, and a first bearing is accommodated on the stator. frame and driving gear, a second bearing is accommodated on the mounting frame, and the other end of the rotating shaft passes through the driving gear and the second bearing, so that the driving gear is located between the first bearing and the second bearing. The present invention also provides an electrical device using the above-mentioned driving device. The electrical device includes a housing and an impeller. The driving device is installed on the housing. The driving device is connected to the impeller to drive the impeller to rotate. In the electrical equipment of the present invention, the driving gear in the driving device is placed on the rotating shaft, and the driving gear is located between two bearings, so as to reduce the noise of the driving device during operation, and further reduce the noise of the electrical equipment during operation.

Description

technical field [0001] The invention relates to a driving device, in particular to a low-noise driving device and electrical equipment using the driving device. Background technique [0002] The driving device of the existing electrical equipment, such as the driving device of the fan, usually consists of a motor and a gear box. The gear box includes a driving gear and a driven gear meshed with the driving gear, the motor shaft is connected with the driving gear of the gear box, and the driven gear is connected with the fan impeller through another shaft; when the motor shaft is driven to rotate , drives the driving gear and the driven gear to rotate, and the rotation of the driven gear drives the fan impeller to rotate. [0003] In the conventional design, usually two bearings are placed in the stator of the motor and sleeved on the shaft of the motor to support the shaft of the motor, and the driving gear connected to the shaft of the motor is located outside the two bear...
