Embodiment 1

[0061] An embodiment of the present invention provides a drive device for reading a recording medium.

[0062] figure 1 is an exploded view of one embodiment of the drive, figure 2 is a cross-sectional view of one embodiment of the driving device, image 3 is a cross-sectional view of another embodiment of the driving device, Figure 4 is a part of a sectional view of an embodiment of the driving device. Such as Figure 4 As shown, the recording medium D is disposed on the axially lower side of the drive device, that is, Figure 4 shown on the underside.

[0063] Such as Figure 1-Figure 4 As shown, the driving device includes: a shaft 100, a sleeve bearing 200, a bearing bush 300, a disk core 400, a plate member 500, and a cover member 500'. Wherein, the shaft 100 is configured to be able to rotate around the central axis O; the sleeve bearing 200 is positioned radially outside the shaft 100 to rotatably support the shaft 100; the bearing bush 300 is positioned radial...

Embodiment 2

[0082] This embodiment provides a data reading and turning device, and the data reading and turning device is used for reading a recording medium. Figure 7 It is a part of the cross-sectional view of an embodiment of the data reading rotary device of this embodiment, such as Figure 7 As shown, the data reading rotary device includes: a motor 1000 , a loading part 2000 and a driving part 3000 .

[0083] In this example, if Figure 7 As shown, the motor 1000 is configured to be rotatable around a central axis O. The motor 1000 has components such as a shaft 1001, a rotor 1002, and a stator 1003. In addition, the motor can also have other components, such as bearings, bearing sleeves, magnets, etc. The specific composition and structure can refer to the prior art, and will not be repeated here. .

[0084] In this example, if Figure 7 As shown, the loading unit 2000 is located on the side of the motor 1000 close to the recording medium D, that is, Figure 7 The upper side of...

Embodiment 3

[0089] This embodiment provides an electrical product, which has the data reading and turning device of Embodiment 2. Since the data reading and turning device has been described in detail in Embodiment 2, its content is incorporated here, and will not be repeated here.

[0090] The electrical product in this embodiment may be any electrical product using a data reading rotary device, for example, it may be a car audio device using a data reading rotary device. However, this embodiment is not limited thereto. The data reading and turning device in Embodiment 1 can also be used as a data reading and turning device in various information equipment, industrial equipment, etc., such as computer equipment, laptop computer equipment, etc.

Abstract

A driving device, a data reading rotary device and an electrical product. The driving device is used for reading the recording medium, and has: a shaft; a sleeve bearing located radially outside the shaft; a bearing bush located radially outside the sleeve bearing; a disc core located close to the shaft One side of the recording medium; and a plate member, which is located on the side of the shaft away from the recording medium, and accommodates the end of the shaft on the side away from the recording medium; it is characterized in that, on the surface of the side of the disc core away from the optical disc An oil-proof component extending radially is arranged between the surface of the bearing bush and the side close to the optical disk; an axially through hole is arranged on the oil-proof component, the aforementioned shaft passes through the hole, and the oil-proof component passes through The hole is fixed to the aforementioned shaft. By providing the oil-proof member in the driving device, it is possible to prevent the oil leaked from the driving device from corroding the components of the driving device.

Description

technical field [0001] The invention relates to the field of motors, in particular to a driving device, a data reading rotary device and electrical products. Background technique [0002] A recording medium, such as an optical disc, is a medium for storing data such as video files, audio files, and data files. Due to its large storage capacity and convenient reading, it has been widely used in the field of data storage. [0003] In the past, when reading an optical disc, it is usually single-sided reading, that is, data is recorded on only one side of the optical disc, so the reading efficiency is not high. [0004] It should be noted that the above introduction of the technical background is only for the convenience of a clear and complete description of the technical solution of the present invention, and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in the art just b...
