背景技术
目前,对于大型旋转设备而言,由于其旋转过程产生大量热量,因此需要使轴承浸泡在油箱内以降低轴承温度。
以抽水蓄能大型旋转设备发电电动机为例,发电电动机具有旋转件,旋转件表面外伸有滑转子,导轴承和推力轴承与滑转子接触,其中导轴承与滑转子侧面接触以限制轴径向移动,推力轴承与滑转子底面接触以限制滑转子轴向移动,导轴承、滑转子、推力轴承均浸泡在油箱内,以降低导轴承、滑转子以及推力轴承的温度。
然而,由于轴承浸泡在油箱内,滑转子相对轴承的转动同时对油箱内的润滑介质产生搅动作用,从而使得油箱内产生泡沫以及油雾现象,油雾溢出油箱附着在发电机上可能导致短路现象,影响发电电动机的安全稳定运行;此外,在旋转件旋转过程中,还会使逆着旋转方向的上游轴瓦流出的热油进入顺着旋转方向的下游轴瓦处,这降低了轴瓦润滑冷却效果。
技术问题内容
本申请提供一种轴承润滑结构以及旋转设备,旨在解决目前大型旋转设备轴承润滑容易出现油雾以及润滑冷却效果差的技术问题。
发明内容
第一方面,本申请提供一种轴承润滑结构,包括:
旋转件;
多个轴瓦,多个轴瓦绕旋转件环形阵列布置;
多个隔热供油组件,隔热供油组件位于相邻的轴瓦之间;
其中,隔热供油组件包括喷油管以及隔油板,隔油板与旋转件接触,且喷油管至少向隔油板一侧供油。
在一些实施例中,喷油管上开设有沿其轴线方向延伸的开口;
隔油板安装于开口内,且隔油板的宽度小于开口的宽度。
在一些实施例中,隔油板将开口分隔为第一喷油口以及第二喷油口,第一喷油口和第二喷油口分别位于隔油板相对的两侧。
在一些实施例中,第一喷油口和第二喷油口相对于隔油板对称布置。

滑动座背离固定座的一侧具有与开口平齐的安装面,安装面上安装有调整板,调整板与隔油板连接。
在一些实施例中,调整板设置有与开口相对的通孔;
通孔的横截面积沿远离开口的方向逐渐增大。
在一些实施例中,隔热供油组件还包括第一支架以及第二支架,第二支架可拆卸地安装于第一支架上,固定座固定设置在第二支架上。
在一些实施例中,隔油板包括固定板以及升降板;

在一些实施例中,升降板的材料为聚醚醚酮或聚四氟乙烯。
第二方面,本申请提供一种旋转设备,包括如第一方面所述的轴承润滑结构。
本申请通过在相邻的轴瓦之间布置隔热供油组件,由于隔油板与旋转件接触,通过隔热供油组件的隔油板隔开相邻的轴瓦,可以避免热油在相邻两轴瓦间相互传递的现象,在减少进入轴瓦的热油量的同时,能够增大进入轴瓦的冷油量,有利于降低轴瓦的工作温度;同时,由于喷油管可以至少向隔油板一侧供油,因此喷油管以喷淋的方式对轴瓦进行供油润滑,无需将旋转件与轴承均浸泡在润滑介质内,从而避免了旋转件搅动产生的泡沫以及油雾现象。

本申请实施例提供一种轴承润滑结构以及旋转设备,以下分别进行详细说明。
首先,参阅图1以及图2,图1示出了本申请实施例中轴承润滑结构的一种正视图,图2示出了本申请实施例中轴承润滑结构的一种左视图,其中,轴承润滑结构包括:
旋转件10;
多个轴瓦20,多个轴瓦20绕旋转件10环形阵列布置;
多个隔热供油组件30,隔热供油组件30位于相邻的轴瓦20之间;
其中,隔热供油组件30包括喷油管31以及隔油板32,隔油板32与旋转件10接触,且喷油管31以至少向隔油板32一侧供油。
具体的,旋转件10是指任意大型旋转设备的转动物体,例如发电电动机、水泵水轮机、风力发电机等的转动轴的轴身,又例如连接在发电电动机的转动轴上并随其转动的滑转子或者镜板。一般地,旋转件10上承载有部分转动件,以发电电动机为例,发电电动机的转动轴上安装有转子,转子周围布置有定子,通过转子切割定子的磁场线,从而进行发电。
在本申请的一些实施例中,参阅图3,图3示出了本申请实施例中旋转件10与轴瓦20配合的一种结构示意图,发电电动的转动轴包括轴身11,滑转子12连接于轴身11上,滑转子12在垂直于轴身11轴线方向布置有镜板13,轴瓦20与镜板13下表面接触,从而实现发电电动的转动轴轴线方向的支撑的目的,同时油箱50包裹滑转子12、轴瓦20部分,以避免润滑油泄漏的现象。可以理解,上述与镜板13接触的轴瓦20为推力轴承瓦21,实际上轴瓦20也可以为导轴承瓦 22,例如安装在滑转子12侧面的导轴承瓦22,以限制发电电动的转动轴径向方向的移动。
在本申请的一些实施例中,发电电动的转动轴可以竖直布置或者水平布置,例如卧式发电机或立式发电机的转动轴。可以理解地,发电电动的转动轴还可以倾斜布置。
轴瓦20绕旋转件10环形阵列布置,用于限制旋转件10的径向移动和/或轴向移动。在本申请的一些实施例中,例如对于旋转件10包括滑转子12和/或镜板13的实施例,参阅图3,轴瓦20包括多个导轴承瓦22,多个导轴承瓦22环形阵列间隔布置且与滑转子12背离轴身11的表面接触;和/或轴瓦20包括多个推力轴承瓦21,多个推力轴承瓦21环形阵列间隔布置且与镜板13接触。其中,导轴承瓦22限制旋转件10径向移动,推力轴承瓦21限制旋转件10轴向移动,从而实现轴瓦20限制旋转件10径向移动和轴向移动的目的。可以理解地,轴瓦20可以与其他结构组成轴承结构,例如轴承座、绝缘板等。
隔热供油组件30用于隔开相邻两轴瓦20间的热油,同时提供喷淋式的润滑,以实现瓦间隔油以及瓦间供油的目的。其中,隔热供油组件30包括喷油管31以及隔油板32,隔油板32与旋转件10接触,且喷油管31至少为隔油板32的一侧供油。在本申请的一些实施例中,喷油管31背离旋转件10的一端与输油管40连接,以实现对喷油管31供油的目的。在本申请的一些实施例中,例如对于轴瓦20包括多个推力轴承瓦21的实施例,隔油板32和喷油管31沿旋转件10的径向方向布置,从而在径向方向阻隔相邻推力轴承瓦21之间的热油传递过程。在本申请的另外一些实施例中,例如对于轴瓦20包括多个导轴承瓦22的实施例,隔油板32和喷油管31沿旋转件10的轴线方向布置,同时隔油板32与滑转子12的表面接触,以避免相邻导轴承瓦22之间的热油传递过程。
在本申请实施例中,通过在相邻的轴瓦20之间布置隔热供油组件30,由于隔油板32与旋转件10接触,通过隔热供油组件30的隔油板32隔开相邻的轴瓦20,可以避免热油在相邻两轴瓦20间相互传递的现象,在减少进入轴瓦20的热油量的同时,能够增大进入轴瓦20的冷油量,有利于降低轴瓦20的工作温度;同时,由于喷油管31可以至少为隔油板32的一侧供油,因此喷油管31以喷淋的 方式对轴瓦20进行供油润滑,无需将旋转件10与轴承均浸泡在润滑介质内,从而避免了旋转件10搅动产生的泡沫以及油雾现象。
进一步的,在本申请的一些实施例中,参阅图4以及图5,图4示出了本申请图1中A处的一种放大示意图,图5示出了本申请实施例中喷油管31的一种结构示意图,其中,喷油管31上开设有沿其轴线方向延伸的开口311,隔油板32安装于开口311内,且隔油板32的宽度小于开口311的宽度。由于隔油板32安装于开口311内,可以减小喷油管31与隔油板32所占据的空间,不仅便于实现隔热供油组件30的安装,同时也可以增大喷油管31的直径以提高润滑油供给量;同时,由于隔油板32的宽度小于开口311的宽度,也就是说隔油板32未完全堵住开口311,喷油管31内的润滑油可以通过开口311在隔油板32处的缝隙喷出,不仅可以实现润滑油供给,同时通过开口311在隔油板32处的缝隙可以提高润滑油的喷射速度,进而实现更好的喷淋润滑效果。可以理解地,喷油管31和隔油板32还可以并排安装。
在本申请的一些实施例中,继续参阅图4,隔油板32将开口311分隔为第一喷油口312以及第二喷油口313,第一喷油口312和第二喷油口313分别位于隔油板32相对的两侧。对于抽水蓄能的发电电动机而言,发电电动机作为发电机使用和作为电动机使用时,两种工况的旋转方向是不同的,因此轴瓦20之间的热油传递方向是不同的,需要供给的润滑油方向也是不同。参阅图6以及图7,图6示出了本申请实施例中旋转件10向第一方向旋转时的一种润滑示意图,图7示出了本申请实施例中旋转件10向第二方向旋转时的一种润滑示意图,由于第一喷油口312和第二喷油口313分别位于隔油板32相对的两侧,因此无论发电电动机正转还是反转,第一喷油口312和第二喷油口313均可以向旋转方向下游的轴瓦20提供润滑油,进而实现发电电动机双向旋转供油的目的。
在本申请的一些实施例中,第一喷油口312和第二喷油口313相对于隔油板32对称布置,也就是说,第一喷油口312和第二喷油口313可以提供流量相当的润滑介质,无论发电电动机正转还是反转,均可以保证轴瓦20的润滑效果。
在本申请的一些实施例中,继续参阅图4,隔热供油组件30还包括固定座33以及滑动座34;滑动座34可滑动的安装在固定座33上,喷油管31安装在滑动 座34上。在进行隔热供油组件30安装或者检修时,可以通过移动滑动座34将喷油管31以及隔油板32安装在轴瓦20之间或者将喷油管31以及隔油板32取出,进而可以降低隔热供油组件30安装难度以及检修难度。
在本申请的一些实施例中,例如对于轴瓦20包括多个推力轴承瓦21的实施例,滑动座34相对的固定座33的滑动方向是沿着旋转件10的径向方向的。在本申请的另外一些实施例中,例如对于轴瓦20包括多个导轴承瓦22的实施例,滑动座34相对的固定座33的滑动方向是沿着旋转件10的轴线方向的。
可以理解,滑动座34相对于固定座33的固定可以通过螺钉、销钉或挡块实现,以避免在喷油管31工作过程中随滑动座34滑动的现象。
进一步的,继续参阅图4,在本申请的一些实施例中,滑动座34具有容纳喷油管31的弧形凹槽341,喷油管31嵌入弧形凹槽341。滑动座34背离固定座33的一侧具有与开口311平齐的安装面342,安装面342上安装有调整板35,调整板35与隔油板32连接。由于喷油管31固定在滑动座34的弧形凹槽341内,弧形凹槽341可以包裹住喷油管31,从而更好的固定喷油管31,避免因喷油管31喷出润滑介质压力过大而导致其自身晃动的现象;同时,通过调整板35安装隔油板32,也可以提高隔油板32的稳固性,避免旋转件10在转动过程中导致与其接触的隔油板32晃动,进而导致隔油板32隔绝热油性能下降的情况。
示例性地,调整板35可以直接焊接在隔油板32侧面上,以便于将隔油板32安装在滑动座34上。可以理解地,调整板35还可以与隔油板32通过螺栓或者铆钉实现连接。
在本申请的一些实施例中,参阅图8,图8示出了本申请实施例中隔热供油组件30的另外一种结构示意图,其中,隔热供油组件30还包括第一支架36以及第二支架37,第二支架37可拆卸地安装于第一支架36上,固定座33固定设置在第二支架37上。第一支架36和第二支架37用于为固定座33提供支撑功能,以使得喷油管31以及隔油管32靠近旋转件10(例如滑转子12或镜板13),在机组内安装时,可以在安装推力轴承以及轴瓦20时同步安装隔热供油组件30时,而在后期抽水蓄能电站检修时,可以通过拆卸第二支架37取下隔热供油组件30需检修的部分(例如滑动座34、喷油管31以及隔油板32等),而无需取下整个推力 轴承或者轴瓦20,进而有利于降低隔热供油组件30的检修难度。
进一步的,继续参阅图4、图9以及图10,图9示出了本申请实施例中隔油板32与调整板35的一种结构示意图,图10示出了本申请实施例中隔油板32与调整板35的一种俯视图,在本申请的一些实施例中,调整板35设置有与开口311相对的通孔351,通孔351的横截面积沿远离开口311的方向逐渐增大,在流体流至通孔351处时,由于通孔351的横截面逐渐增大,通孔351较窄的地方可以加速润滑介质喷射速度,而在较宽的地方可以加大润滑介质喷淋的区域,从而通过调整板35处的通孔351提升隔热供油组件30的喷淋润滑效果。
在本申请的一些实施例中,参阅图9,隔油板32包括固定板321以及升降板322,固定板321邻近旋转件10的一面开设有第一条形凹槽3211,升降板322安装于第一条形凹槽3211内。在相邻的轴瓦20间安装好隔热供油组件30后,隔油板32的升降板322与旋转件10接触,由于升降板322安装于第一条形凹槽3211内,因此在进行隔热供油组件30检修时,可以只用更换升降板322,而无需更换整个隔油板32,不仅可以降低检修难度,同时还可以降低检修成本。示例性的,升降板322的材料为聚醚醚酮或聚四氟乙烯耐磨润滑材料,通过聚醚醚酮或聚四氟乙烯耐磨润滑材料良好的耐高温性、机械特性、自润滑性提升隔油板32的热油隔绝性能。
在本申请的一些实施例中,继续参阅图9,第一条形凹槽3211内安装有弹簧323;弹簧323一端固定于第一条形凹槽3211底部,另外一端与升降板322接触。在隔热供油组件30工作过程中,弹簧323处于压缩状态从而产生弹力,该弹簧323使得升降板322保持与旋转件10的接触状态,从而保证隔油板32的热油隔绝性能。
可以理解地,弹簧323也可以采用其他弹性件替代,例如橡胶弹性件。
进一步的,在本申请的一些实施例中,参阅图11以及图12,图11示出了本申请实施例中隔油板32与调整板35的一种正视图,图12示出了本申请图11中B处的一种放大示意图,其中,升降板上设有沿第一条形凹槽3211深度方向的限位孔3221;固定板321上安装有限位件3212,限位件3212嵌入限位孔3221内,且限位孔3221沿第一条形凹槽3211深度方向的长度大于限位件3212的直径。由 于限位件3212以及限位孔3221的配合,升降板的上下移动距离即为限位孔3221沿第一条形凹槽3211深度方向的长度,因此可以避免升降板与旋转件10接触过紧或过松的现象。示例性地,限位件3212可以为销钉或者螺钉。
进一步的,继续参阅图9,在本申请的一些实施例中,升降板322邻近旋转件10的一面设有第二条形凹槽3222;升降板322具有位于第二条形凹槽3222两侧的第一刮油部3223以及第二刮油部3224,第一刮油部3223和第二刮油部3224与旋转件10接触,由于升降板322与旋转件10同时在两处接触,进而可以实现两级隔油以及刮油的目的。
可以理解地,还可以在升降板322邻近旋转件10的一面设置更多数量的第二条形凹槽3222,以使升降板322具有更多数量的刮油部,进一步提升隔油板32的隔油以及刮油性能。
进一步的,在本申请的一些实施例中,参阅图11,固定板321侧面设有贯穿至第一条形凹槽3211的螺纹孔3213,螺纹孔3213内安装有锁定螺钉3214,锁定螺钉3214伸入第一条形凹槽3211并顶住升降板322,锁定螺钉3214可以限制升降板322在第一条形凹槽3211内的晃动现象,以避免升降板322晃动导致隔油板32热油隔绝性能下降的现象。
值得注意的是,上述关于轴承润滑结构以及旋转设备的内容旨在清楚说明本申请的实施验证过程,本领域技术人员在本申请的指导下,还可以做出等同的修改设计,例如将喷油管31设置在隔油板32的上,或者将喷油管31设置在隔油板32相对的两侧面,以实现隔绝热油以及喷淋润滑油的目的。
进一步地,为了更好的实施本申请实施例中的轴承润滑结构,在轴承润滑结构的基础上,本申请提供一种旋转设备,旋转设备包括上述任一实施例的轴承润滑结构,示例性地,旋转设备可以为发电电动机、水泵水轮机、风力发电机等。由于本申请实施例中的旋转设备包含上述实施例中的轴承润滑结构,因此具备上述实施例中轴承润滑结构的全部有益效果,在此不再赘述。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见上文针对其他实施例的详细描述,此处不再赘述。
上文已对基本概念做了描述,显然,对于本领域技术人员来说,上述详细 披露仅仅作为示例,而并不构成对本申请的限定。虽然此处并没有明确说明,本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议,所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
