如何选择变速箱
驾驶车辆时,变速箱负责提供牵引力和速度。低速挡提供最佳牵引力,高速挡提供最高速度。根据驾驶情况选择合适的挡位,可以最大限度地发挥牵引力和速度的优势。合适的挡位会根据路况、载重和速度而变化。低速挡可以加快加速,高速挡可以提高最高速度。但是,在驾驶之前,您应该了解如何使用变速箱。
功能
变速箱的功能是将旋转能量传递给机器的传动系统。输入扭矩与输出扭矩之比,即扭矩与转速之比。变速箱具有多种不同的功能。一个变速箱可能具有多种功能,也可能只有一个功能,但用于驱动多个其他机器。如果一个齿轮不转动,其他齿轮仍然可以带动变速箱转动。这就是变速箱名称的由来。
变距控制系统与电气系统一样,都存在大量故障模式,是造成机器最长停机时间和停工时间的主要原因。机构与故障之间的关系难以用数学模型精确描述。齿轮箱的故障模式如图3所示。齿轮箱的实际使用寿命为六至八年。然而,为了减少停机时间并避免灾难性事故,必须开发成熟的齿轮箱故障检测技术。
变速箱是至关重要的机械部件。它处理发动机产生的能量,从而驱动机器的各个部件运转。变速箱的效率取决于其能量传递的效率。传动比越高,传递到车轮的扭矩就越大。它是自行车、汽车和各种其他设备的常见部件。其四大主要功能包括:
除了确保变速箱的可靠性外,变速箱的可维护性也应在设计阶段进行评估。可维护性方面的考虑因素,例如可用的备件类型,应融入变速箱的设计中。合理的维护方案还将决定特定部件的更换或维修频率。正确的维护程序还能确保变速箱易于检修。无论检修是否方便,可维护性都至关重要。
目的
汽车的变速器连接发动机和车轮,使高速运转的曲轴能够提供更大的动力。高扭矩发动机对于车辆的起步、加速和克服道路阻力至关重要。变速箱降低发动机转速,并向车轮提供不同的扭矩输出。变速器还提供反向动力,使车辆能够前进和后退。
齿轮将动力从一个轴传递到另一个轴。齿轮的尺寸和齿数决定了变速箱能够传递的扭矩大小。更高的齿轮比意味着更大的扭矩,但速度会降低。变速箱的换挡杆带动轴上的啮合部件移动。换挡杆还使齿轮和同步器滑动到位。如果换挡杆向左或向右滑动,发动机将以二挡运转。
齿轮箱需要密切监控,以降低过早失效的可能性。目前有多种测试方法可用于检测齿轮齿缺陷,从而提高机器的可靠性。图 1.11(a) 和 (b) 显示了一个 18 齿、传动比为 1.5:1 的齿轮箱。输入轴连接到一个皮带轮,并驱动一条 V 形皮带。该传动比允许齿轮箱在降低电机转速的同时,增加扭矩并降低输出转速。
说到减速,齿轮箱是降低电机扭矩最常用的方法。扭矩输出与电机的体积成正比。例如,一个小型齿轮箱可以产生与一台输出转速相同的大型电机一样大的扭矩。反之亦然。目前有混合驱动和直列式齿轮箱。无论采用哪种类型,了解齿轮箱的功能将有助于您为特定应用选择合适的齿轮箱。
应用
选择变速箱时,必须考虑使用系数。使用系数是指变速箱实际容量与应用所需容量之间的差值。对变速箱的额外要求可能会导致密封件过早磨损或过热。使用系数应尽可能低,因为它可能决定变速箱的使用寿命。在某些情况下,变速箱的使用系数可以高达 1.4,这足以满足大多数工业应用的需求。
中国在可再生能源行业占据主导地位,拥有1000吉瓦的全球最大装机容量,每年发电量超过2000太瓦时。这些行业的增长预计将增加对齿轮箱的需求。例如,在中国,风能和水力发电是风力发电厂和太阳能发电厂的主要组成部分。装机容量的增长意味着这些行业对齿轮箱的需求将会增加。不适用于特定应用的齿轮箱将无法正常工作,这可能会对中国的产品生产造成不利影响。
变速箱的安装方式有四种。前三种是同心安装、平行安装和直角安装,第四种是轴装式安装。轴装式变速箱通常用于电机无法通过支脚安装的应用场合。下文将详细介绍这些安装方式。选择合适的变速箱对您的业务至关重要,但请记住,设计精良的变速箱将有助于提高您的盈利能力。
变速箱的使用系数取决于负载类型。例如,高冲击载荷会导致齿轮齿或轴承过早失效。在这种情况下,需要更高的使用系数。而在其他情况下,专为承受高冲击载荷而设计的变速箱能够承受此类载荷而不降低其性能。此外,它还能降低变速箱的长期维护成本。
材料
在选择变速箱材料时,必须权衡设计的强度、耐用性和成本。本文将探讨不同类型的材料及其各自的应用和动力传输计算。多种合金可供选择,每种合金都有其自身的优势,包括更高的硬度和耐磨性。以下是一些齿轮中常用的合金。合金的优势在于其价格竞争力。由这些材料制成的齿轮通常比同类材料更坚固。
SPCC的碳含量使其无法像不锈钢那样快速硬化。然而,SPCC薄板通常用于强度较低的齿轮。由于碳含量低,SPCC表面硬化速度不如不锈钢齿轮快,因此需要进行软氮化处理以提高硬度。但是,如果您需要永不生锈的齿轮,则应考虑使用不锈钢或FCD材质。
除了汽车,变速箱在航空航天领域也发挥着重要作用。它们用于太空旅行和飞机发动机。在农业领域,它们用于灌溉、病虫害防治机械和耕作机械。它们也用于起重机、推土机和拖拉机等建筑设备。变速箱还应用于食品加工行业,包括输送系统、窑炉和包装机械。
变速箱齿轮的齿形对变速箱性能至关重要。齿轮啮合良好才能使变速箱发挥最佳性能并承受扭矩。齿轮齿就像微小的杠杆,有效的啮合可以减少应力和打滑。静态参数分析有助于确定整个齿轮运转周期内的啮合质量。这种方法通常是判断齿轮啮合是否良好的最准确方法。
制造业
全球齿轮市场分为五大区域:北美、欧洲、亚太和拉丁美洲。其中,亚太地区预计将创造最大的GDP,这主要得益于能源需求的快速增长和工业基础设施投资。该地区也拥有一些全球最大的制造业基地,其持续兴建的新建筑和住宅将推动齿轮行业的增长。在应用领域,齿轮箱广泛应用于建筑、农业机械和交通运输等行业。
预计未来几年,受建筑业快速发展和商业进步的推动,工业齿轮箱市场将持续扩张。然而,诸多挑战阻碍了该行业的增长,其中包括齿轮箱高昂的运营和维护成本。本报告涵盖了全球工业齿轮箱的市场规模及其制造技术,并包含了2020年至2024年期间的制造商数据。此外,报告还探讨了市场驱动因素和制约因素。
全球健康危机和海运贸易的下滑对该行业产生了一定程度的不利影响。海运贸易的下滑阻碍了投资。预计到2020年4月,国际原油价格将跌破1美元,这将终结新资产的开发和开采。在这种情况下,全球变速箱市场将面临诸多挑战。然而,机遇也十分巨大。因此,得益于国内轻型车辆销量的增长,预计到2020年,工业变速箱市场规模将增长超过6100万吨。
变速箱的主轴,也称输出轴,以不同的速度旋转并将扭矩传递给汽车。输出轴带有花键,以便连接联轴器和齿轮。副轴和主轴由轴承支撑,轴承可以减少旋转部件的摩擦。变速箱的另一个重要部件是齿轮,齿轮的齿数各不相同。齿数决定了齿轮可以传递的扭矩大小。此外,齿轮可以在任何位置滑动。
