    摘要: There are provided a sealing resin composition for a hard disk drive (HDD) motor and a HDD motor fabricated by using the same. The sealing resin composition includes 40 to 80 parts by weight of epichlorohydrin-4,4-isopropylidene diphenol resin; 5 to 20 parts by weight of acrylated ester; and 5 to 15 parts by weight of acrylated epoxy. The sealing resin composition containing a UV curable epoxy resin is used as a sealing material of the adhering part of the FPC of the HDD motor, whereby generation of outgas in the adhering part may be reduced.

    摘要: There are provided an adhesive resin composition for a hard disk drive (HDD) motor and a HDD motor fabricated by using the same. The adhesive resin composition for a HDD motor adheres fixed members and rotating members of the HDD motor to each other and includes 100 parts by weight of a first resin, 25 to 80 parts by weight of a second resin, a hardness of which after hardening is lower than that of the first resin, and 40 to 100 parts by weight of a hardener. The HDD motor is fabricated by using the adhesive resin composition for a HDD motor including a flexible epoxy resin, whereby reliability of the motor against external impacts may be improved.

    摘要: There are provided a hydrodynamic bearing assembly and a manufacturing method thereof. The hydrodynamic bearing assembly includes: an oil sealing part formed between a fixed member and a rotating member; and a silicon containing diamond-like-carbon (Si-DLC) or tungsten carbide (W-Carbide) coating layer formed on at least one surface of the fixed member and the rotating member. The silicon containing diamond-like-carbon (Si-DLC) or tungsten carbide (W-Carbide) coating layer is formed on the at least one surface of the fixed member and the rotating member, whereby abrasion of the fixed member and the rotating member due to friction therebetween may be prevented.

    摘要: There are provided a hydrodynamic bearing assembly and a method of manufacturing the same. The hydrodynamic bearing assembly includes: a lubricating oil filled so as to form a liquid-vapor interface between stationary members and rotating members; and a lipophilic coating formed on the liquid-vapor interface of the lubricating oil so as to prevent lubricating oil leakage. Therefore, the lipophilic coating is formed on the interface of the lubricating oil and an oil repellent material is formed on a surface of at least one of the stationary members and the rotating members, whereby the scattering and the leakage of the lubricating oil may be effectively prevented.

    摘要: There are provided a hydrodynamic bearing assembly and a method of manufacturing the same. The hydrodynamic bearing assembly includes: an oil sealing part formed between a fixed member and a rotating member; and an oil barrier film disposed so as to prevent leakage of oil from the oil sealing part and including a self-assembled monolayer formed on a surface of at least one of the fixed member and the rotating member. The oil barrier film may be easily formed at room temperature and be continuously used for a long period of time without being damaged due to external impacts.
