    Angular Contact Ball Bearings角接触球轴承

    Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing's spherical rolling elements, also called bearing balls, on an angle.角接触球轴承通过不对称的滚道支撑径向和轴向载荷,该轴承容纳轴承的球面滚动体,也称为轴承滚珠。 The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry.轴承与其轴线之间的角度越深,轴承所能承受的轴向载荷就越大。 Because the axial load is proportionate to the radial load, a greater axial load capacity means less radial load capacity.由于轴向载荷与径向载荷成比例,较大的轴向载荷能力意味着较小的径向载荷能力。 Angular contact ball bearings come in single- and double-row configurations depending on the direction of loads they carry.角接触球轴承根据其承载的负载方向而有单列和双列的结构。 Single-row angular contact ball bearings only support axial loads in one direction, while double-row angular contact ball bearings support axial loads in both directions.单列角接触球轴承只支承一个方向的轴向载荷,而双列角接触球轴承支承两个方向的轴向载荷。

    Manufactured to the same close tolerances as the radial type, but designed with contact angles of 15, 30, and 40 deg to accommodate greater thrust loads.制造与径向类型有相同的紧公差,但设计的接触角为15,30和40度,以适应更大的推力载荷。

    A common choice, at higher precision levels, for applications such as machine tool spindles where both accuracy and high thrust loads are present.对于精度高和推力载荷高的机床主轴等应用,通常选择精度更高的应用。 They are typically mounted in pairs, providing thrust capacity in either direction and good rigidity for applications where shaft movement is critical.它们通常成对安装,在任何方向上都能提供推力,在轴的运动非常关键的情况下可提供良好的刚性。

    Double row assemblies offer shaft rigidity, compactness, and higher radial capacity as well as moderate thrust capacity in both directions.双排装配提供轴刚性,紧凑性和更高的径向容量以及双向适度的推力。

    (A). (一个)。 Single row angular contact bearings: 单列角接触轴承:

    Single row angular contact ball bearings can carry thrust load in one direction only, and should always be adjusted against another bearing which accommodates the opposed thrust load.单列角接触球轴承只能在一个方向上承受推力载荷,并应始终相对于另一个适应相反推力载荷的轴承进行调整。 Single row angular contact ball bearings are no separable.单列角接触球轴承不可分离。

    Spindle bearings are a special design of the single row angular contact ball bearings;主轴轴承是单列角接触球轴承的特殊设计; they were developed primarily for high-speed work spindles of machine tools.它们主要是为高速工作机床而开发的。 The spindle bearings differ from the angular contact ball bearings by the contact angle, the degree of accuracy, and the type of cage.主轴轴承与角接触球轴承的接触角,精度和笼型不同。 Spindle bearings are manufactured in series 70 and 72. They are identified by a bearing number commencing with a B.主轴轴承采用系列70和72制造。它们由轴承号码开始标识。

    (B). (B)。 Double row angular contact bearings: 双列角接触轴承:

    The design of the double row angular contact ball bearing corresponds to two single row angular contact ball bearings arranged back to back.双列角接触球轴承的设计与背靠背排列的两个单列角接触球轴承相对应。 The bearing is capable of carrying high radial loads and thrust loads in both direction.该轴承能够在两个方向上承受较高的径向载荷和推力载荷。 It is particularly suitable for applications calling for high axial rigidity.它特别适用于要求高轴向刚度的应用。

    Double row angular contact bearing with unsplit rings are provided with filling slots on one side.双排角接触轴承,带有非分离环,一侧装有填充槽。 The bearings should be mounted in such a way that the main loads are carried by the raceways without filling slot.轴承的安装方式应使主要负载由没有填充槽的滚道承载。
