Description
本发明涉及重型采矿和建筑车辆,更确切地说是涉及具有用铰链接合连接的前、后机架的铰接车和铰链组件。
铰接车的铰链必须承担由负荷、运行、动力系操作和车辆重量所产生的主要作用力,理想情况下,铰链组件不应该过于庞大或过重,而应该容易调正和替换。
最初的现有技术中的装置采用了球轴承,如Casey的美国专利US.3,806,158中所述。因为球轴承具有大的轴承表面接触面积,所以,滚珠—和—座套形式的球轴承的功能,可以承受大的径向和轴向负荷。然而由于球轴承是滑动接触而容易磨损。由结构或采矿环境造成的磨料污染可加剧磨损。
在已有的铰接车技术领域里采用了滚子轴承,以避免由球轴承产生的磨损。但是应用于现有技术领域里的滚子轴承有一些缺点,如重量大、体积庞大以及维护和更换复杂等问题。现有技术领域中有一个装置使用两个滚子轴承组件,第一个轴承组件是大的主轴承,其有双列锥滚子,用以传递机架之间的大部分径向负荷,同时也用以承担全部垂直的轴向负荷。第二个轴承组件包括只传递径向负荷的垂直浮动轴承。第二个轴承组件必须可以浮动,以便适应连接轴承的机架焊件之间产生的容隙。只有通过对焊件表面进行昂贵的机加工,才能在焊件之间获得足够精确的间隙。如果用有一般的焊接误差的机架装入两个相同的锥滚子轴承组件,将在轴承上产生不能接受的轴向预负荷,严重减小轴承承担工作负荷的能力。
惯用滚子轴承的另一缺点是:固定的主轴承一定要承受全部轴向负荷,这就使该轴承庞大、重型。同时浮动轴承可以是小型的,重量轻型的,固定轴承由于庞大和重型而使其在某些应用领域里不理想,例如地下采矿车辆就要求微型轴承。此外,机架本身也必须又大又重,连接固定轴承的焊件传递全部垂直负荷。
采用滚子轴承的现有车辆铰链也难以操作和置换。为达到最大的***刚度,通常调整锥滚子轴承组件的预负荷,目的是将锥环偏压在一起,以便加压锥环和轴承盖间的轴承滚子。为达到最少量的磨损,需要调整轴承使预负荷复原到所要求的大小。调整预负荷要求将现有的滚子轴承组件去除和拆卸。该拆卸过程破环了轴承密封件,显露出组件内部而遭受污染,特别是在现场需要调整时,污染问题尤其严重。此外,轴承组件整体替换通常需要至少两次重新安装原有垫片,以便使新轴承达到所要求的预负荷。现场操作和装配需要寻常不通用的专用工具,这就使车辆的成本提高。
因为已有的铰接车铰链组件存在上述问题,需要有克服这些问题的有效的铰接车铰链组件,因此这就是本发明的主要目的。
另外本发明的重要目的是:
提供上述铰接车铰链组件,该组件不易受磨损;提供上述组件,该组件具有有限的尺寸和重量,以用于小型车辆;提供上述组件,该组件在装配到车辆以前行操作和预调整;提供上述组件,该组件在不损环轴承密封件的条件下可调整。提供上述组件,该组件在不拆卸车辆的情况下可调整预负荷;
根据本发明叙述的实施例,通过提供铰接车的铰链组件可达到本发明的主要目的,铰链组件包括带有两个整体座板的前机架部分,每个座板都有连接的锥滚子轴承组件,组件带有可转动的突出轴颈。后机架部分包括相应的挖槽和安放轴颈的轴颈盖。各轴承组件尺寸相等,共同分担径向和轴向负荷,轴颈包括间隔安放的第一和第二锥环的端轴,其间隙由邻接第一锥环的台肩确定,并由端轴上的压缩环确定,压缩环邻接第二锥环,由连接轴端的端盖制约。端差和轴端之间的垫片确定和限制了锥环之间的间隙。轴承预负荷可以调整,调整方法是松弛一个轴颈盖,除去端盖,用不同厚度的垫片替换原有垫片,再安放上端盖,并重新固定轴颈盖。

图2是图1实施例中铰链组件的剖面侧视图;
图3是图1实施例中铰链组件的顶视图;
图4是图1实施例中轴承组件的剖面侧视图;
图5是本发明另一个实施例的轴承组件的剖面侧视图。
图1表示一个铰接的采矿车10下部轮廓图,矿车10设有通过上铰链组件18和下铰链组件20连接在一起的前机架部分12和后机架部分14,为能在竖直的铰链轴22上转动设置铰接的连轴节。后机架部分14包括动力装置26,一对后轮28和操作室30。前机架部分12包括前轮34和位于采矿车前方的料斗组件36。
图2显示上铰链组件18,其结构和功能基本上和下铰链组件20相同。后机架14包括上部的后座板40和下部的后座板42。座板在水平方向相间隔开的平行平面上伸出。前机架12包括向后伸出的前座板44,前座板44位于水平方向并交叉在后座板40和42中间。
轴承组件48具有连接前座板的外固定部分50和轴颈连接在固定部分中的可转动的圆柱形轴颈52,轴颈带有由轴承组件48垂直向上和向下延伸的圆柱部分54,并连接后座板40,42。
前座板44包括圆周加强部分56,该部分分别从前座板44的上、下表面的上方和下方突出。加强部分56中央安设一个机加工的圆孔58,圆孔58对准垂直于座板44的竖轴线。加强部分56还确定穿通加强部分56的均匀相间并圆周排列的间隙钻孔60。座板44还设有确定通道66的管道62,连通孔口(未示出)至孔58外,以便将润滑剂带入孔中。
如图3所示,上部后座板40向前终止于平表面68,后座板40还确定具有在平表面68平面中的垂直轴线并在平面中央的半圆槽70。轴颈盖74上设半圆槽76,利用螺栓78可拆卸地紧固到后座板40上,以便紧固地夹持轴颈52的圆柱部分54。圆柱部分54和半圆槽70,76的曲率半径大致相等,用以在轴颈和槽之间提供最大的接触面积。
图4表示不包括采矿车构件的轴承组件48,通常使用时将轴承组件连到采矿车上。如上述轴承组件48包括由固定部分50包围的可转动轴颈52。固定部分50设置圆柱插环82,该外径紧密地放置在如图2所示的孔58中。插环82的高度等于加强部分56的厚度,插环上设有若干圆周沟槽84,以利于由管道62提供的润滑剂的循环。许多径向孔(未示出)将润滑剂从沟槽84传送至环82的内部。双列环轴承套88紧紧压配在环82中,轴承套88上有一对面向里的锥环90、92,上锥环90表面稍微向上,下锥环92表面稍微向下,轴承套88设有许多将润滑剂传送至锥环90,92的润滑剂孔94。在轴承套88的上方和下面对置安放一对轴承夹持板96,98。各夹持板的外径与前座板44的加强部分56的外径相一致(见图2),各夹持板上包括与前座板上的间隙孔60对中的系列大通孔100和扩孔加工的间隙孔102,如图3所示。再回来参看图4,各个板96,98都设有装轴密封件108的中央小孔106,以便紧密密封地安放轴颈52伸出的圆柱部分54。各板96,98还包括和小孔106同心并和套88直径相等的凸缘110,凸缘110伸出的量足以到达板表面上方,因此,当套88压在凸缘110之间时,插环82不会与板的两个表面接触。其结果,插环82只是径向对准在孔58中,并不能限定板96,98相互之间的相对轴向位置,或者相对前座板44的轴向位置。
参照图2,利用许多螺栓114穿过间隙孔60把各夹持板96,98固定到前座板44。螺栓头放置在扩孔加工的间隙孔102中,而螺栓尾端装上螺母116安放在通孔100中。如图2和图3所示,各夹持板96,98通过6个均匀间隔的螺栓114装到前座板44上,夹持板之间的间距,由套88的高度确定,仅仅在第一次安装时,使下夹持板98压靠前座板44。
如图4所示,轴颈52包括轴柱118,轴柱带有与铰链轴线22同轴的圆柱部分120;以及同轴圆柱头部124,圆柱头部124的外径大于圆柱部分120的外径,以便设置台肩126。头部124由轴密封件108密封,并作为轴颈的下部伸出的圆柱部分54。圆柱部分120终止于头部124对面的垂直铰链轴线22的端面128。轴柱118的端部有许多螺纹孔130。
第一轴承锥环134上具有锥形环表面136,将锥环134紧密安放在圆柱部分120,以连接台肩126定位锥环,因此锥环表面136一般径向面向外,轴向稍微离开轴柱118的头部124。第一组锥形滚子轴承138安装在第一锥环134周围,与套88的下环92相接触,第二锥环142和第一锥环134相同,安装在圆柱部分120上,只是对置方向不同,所以锥环138和142在相反方向上倾斜。第二锥环142有锥形环表面144,锥形环表面144径向面向外,轴向稍微朝向轴柱118的端头124。第二组锥形滚子轴承146安装在第二锥环142和套88的上环90之间。
图4所示的最佳实施例中,第一和第二锥环134和142用间隙148隔开。间隙148的宽度由滚道表面和滚子间的轴向分力确定。因此,偏压轴承锥环将产生轴承组件的预负荷。也就是说,即使轴承组件48未受负荷时,滚子也将在滚道之间受压力。在需要有最大的***刚度的场合,这种预负荷是有利的。
坚固的隔离环152紧密地安置在轴柱118的圆柱部分120上,因此隔离环邻接第二锥环142。隔离环152的外径和轴柱头部124的外径相等,因此隔离环152有足够的高度使之延伸超过上部轴密封件108,密封件装配时圆周边密封。剖分隔离环154紧密放置在圆柱部分120上,邻接隔离环152。如图2所示,剖分隔离环154的高度大于上部后座板40的厚度,以提供夹紧座板和轴颈盖74的端面。剖分隔离环154是剖分式的,使轴颈盖74夹紧产生的压力传递到轴柱118,防止产生滑动。剖分隔离环154通常在轴柱端128上延伸很短距离。如图4所示,这段距离造成垫片或成组垫片158的沟槽,在没有延伸到剖分隔离环154上方的条件下,垫片158放置靠在端部128上。
由刚性圆板构成的端盖160的外径等于轴柱头部124的直径,端盖160和垫片158面对面地对准剖分隔离环154,端盖160上有许多对准轴柱118的螺纹孔130的间隙孔162,螺纹孔130里装有许多螺栓164,强制剖分隔离环154有力接触垫片158,并强制隔离环152和第二锥环142朝向第一锥环134,增加组件的预负荷。锥环间的间隙148和预负荷值由垫片158的厚度所限,其提供了可靠的制动防止螺栓164过紧。同时,隔离环152和剖分隔离环154,端盖160和螺栓164共同构成一个压缩元件。轴柱118头部124有中心孔168,用于连接扭矩板手,通过测定转动阻力来测试组件的预负荷。
图5表示另一实施例的轴承组件48′,其与图4中实施例的区别在于轴承组件48′采用了不同的垫补方案。替换组件48′包括位于第一锥环134和第二锥环142之间的垫片环170,整个占据了间隙148,锥环邻接垫片环170的对置的侧面。取消了图4中的垫片158,存留锥环端部128和端盖160之间的端部间隙172。垫板环170的厚度确定锥环134和142隔开的距离,因此也确定轴承的预负荷值。装配时,用螺栓把端盖160拧入轴柱118,加压于隔离环152和154,锥环134和142,以及垫片环170,靠住台肩126。虽然为替换装入垫片环170必须拆卸组件48′但该实施例为达到预计的预负荷值而在锥环之间产生了绝对精确的间隙。
轴承盖,锥环和滚子相当于63788和67322D号零件,这些零件可从ohio,Canton的Timken公司购买。这些零件也包括垫片环170,该零件在图1至图4的最佳实施例中被拆除。最佳实施例的轴承有直径达5英寸的孔,以安放相同直径的轴柱。
最佳实施例的轴承组件48进行装配以前可大量进行组装,调整和试验。局部组件包括整个轴承组件48除去夹持板96、98。局部组件是顺序地将下列零件装配在轴柱118的圆柱部分120构成的;(1)第一锥环134,(2)第一轴承组138,(3)轴承套88连同其相连的插环82,(4)第二组滚子轴承146,(5)第二锥环142,(6)隔离环152以及,(7)剖分隔离环154,同时垫片158放在轴柱端部128上,然后用端盖160固定。当不进行防污染的密封时,局部组件可在工厂环境下进行扭转试验和调整,不需要为工厂或现场装配而顺序拆卸。
装配到车辆上时,将下夹持板98螺栓拧到座板44的下侧面,因此可以上面装配局部组件,轴柱头部124滑动穿过下轴密封件108,插环82紧密地放置在孔58中。然后从上面装配上夹持板96,因此上轴密封件108向下滑动穿过端盖160和剖分隔离环154,隔离环152。然后用螺栓将上夹持板96固定到座板44上。
随着装配在车辆前部的轴承组件48,定位车辆的后部分14,将轴颈52的伸出的圆柱部分对准在后座板半圆柱槽70中。这样定位,使轴颈盖74进行装配,以便牢固地夹紧轴柱头部124和剖分隔离环154。后座板分开的距离足够大,以便在各座板和各个轴承夹持板之间留有间隙170。这就使轴颈能在垂直位置间的任何部位装配,于是容许在各种不同的机架座板之间有较大的垂直尺寸误差。
对于在现场更换损环的或过量磨损的轴承组件来说;与装配步骤相反进行。采用原有的装配程序安装更换的轴承组件,注意防止接触通常由轴密封件保护的滚子轴承被污染。
在基本上不拆卸的情况下,或者在不防碍轴承密封件的情况下,在现场可容易调整轴承预负荷。如果轴承正常磨损,则预负荷值下降,低于所要求的标准,用较薄的垫片部件替换现有的垫片部件将使锥环间的间隙减小,从而增大了预负荷,为进行有效地再调整,将上轴颈盖74松弛,使剖分隔离环154相对轴柱118产生轴向滑动。然后沿端盖160拆卸螺栓164。此后用薄垫片部件替换垫片部件158,重新装上端盖和螺栓,使隔离环和第二锥环靠近第一锥环。密封件108不受任何阻碍,通过再调整过程,用保持固定到轴柱端部124的下轴颈盖74,车辆处于整体组装状态。
上述的最佳实施例中已说明和阐述了本发明的原理,对于该技术领域中的普通技术人员来说,很明显,在不脱离本发明原理的条件下在安排和细节上可进行修改。要求保护的发明不仅包括叙述的实施例,同时也包括下述权利要求的构思和范围中所有的改型,变更和与其相当的实施例。
