    • PURPOSE: A bearing holder is provided to simplify a gear box assembling process by reducing the number of parts and costs. CONSTITUTION: A bearing holder includes a plate-type body, a hole (32), a plurality of hooks (34), and a plurality of protrusion units (42). The plate-type body has a first later surface and a second lateral surface. The hole penetrates through the body and measures off a void for receiving a bearing with an axis and a radial direction. The hooks are extended from the first lateral surface of the body and form a first axial stepped portion controlling the axial movement of the bearing in a first axial direction. The protrusion units are extended from the second lateral surface of the body and become transformed in a radial direction to form a second axial stepped portion controlling the axial movement of a second axial direction of the bearing passing through the void.
    • 目的:提供一个轴承座,通过减少零件数量和成本来简化齿轮箱装配过程。 构成:轴承座包括板状主体,​​孔(32),多个钩(34)和多个突起单元(42)。 板状体具有第一后表面和第二侧表面。 该孔穿过本体并且测量用于接收具有轴线和径向方向的轴承的空隙。 钩体从主体的第一侧面延伸并且形成第一轴向台阶部分,其控制轴承在第一轴向方向上的轴向运动。 突出单元从主体的第二侧表面延伸并且在径向方向上变形以形成第二轴向阶梯部分,其控制通过空隙的轴承的第二轴向的轴向运动。

    • PURPOSE: A hydrodynamic bearing module and a spindle motor with the same are provided to improve an ipsilateral property and to increase the length of a span between dynamic pressure generating grooves. CONSTITUTION: A hydrodynamic bearing module includes a rotary shaft (10), a sleeve (20), and a hub (30). The sleeve supports the rotary shaft to be rotatable. The hub is joined to the top of the rotary shaft. Upper and lower radial kinetic pressure bearing units are formed inside a minute gap between the rotary shaft and the sleeve. A thrust kinetic pressure bearing unit is formed inside the minute gap between the rotary shaft and the sleeve in an axial direction of the rotary shaft. The thrust kinetic pressure bearing unit is arranged between the upper and lower radial kinetic pressure bearing units.
