Description

脂润滑轴承系统 技术领域
本发明涉及一种能进行润滑脂过滤和/或冷却的脂润滑轴承系统,属于脂润滑轴承领域。
背景技术
轴承的润滑主要有两种方式,一种液态油润滑,这类轴承必须是设置在箱体内的,箱体内盛放有油液,这类润滑的效果好,清洁度高,但是并不适用于所有轴承,因为有些轴承无法设置在壳体内部,如应用于风力发电设备、建筑机械等中的轴承就属于这类轴承,这类轴承需要采用润滑脂进行润滑,润滑脂的粘稠度较大,不易流出,在轴承内、外圈之间的润滑空间完全封闭的情况下,不易大量流出。随着时间的流逝,润滑脂会老化,变硬,流动性变差,不能满足润滑需要,这时就需要改善润滑空间内润滑脂的流动性,现有技术中会通过供脂装置对轴承提供润滑脂,供脂装置具有润滑泵,润滑泵一般为柱塞泵或者齿轮泵,润滑泵连接块式分配器,分配器分别与各个轴承上的各个注油孔连通。随着新鲜润滑脂的注入,老化后的旧润滑脂会从轴承结构上所开的出油口被挤出,为了防止出来的旧润滑脂污染环境,会在排油孔上设置润滑脂收集瓶,首先,定时排空这些有时很难接近的瓶子是很麻烦的。此外存在这样的危险,即如果瓶子没有及时排空,润滑脂便不受控制地从润滑脂收集瓶中流出。另外,由于旧油脂的粘稠度大、硬度高,需要很大的力量才能将其挤出来,这就造成了在很多时候,挤出旧油脂的压力高于轴承油封的耐压力,造成油脂由油封结构处流出的问题,流出来的甚至是粘稠度小的新润滑脂,造成润滑脂收集瓶中没有收集到润滑脂,润滑脂都由轴承结构中流出来了,污染环境不说,还会造成轴承润滑不良,同时,润滑脂浪费严重,增加润滑成本。为了解决这一问题,现有技术中通过润滑脂吸排装置来抽吸轴承内部的旧油脂。润滑脂吸排装置会将流动性差的润滑脂抽出来,一般来说抽吸出来的润滑脂都会被直接丢掉,为了实现最大利用价值,抽吸不会特别及时,一般要等到润滑脂老化变质以后才会被抽吸出来,但是,在轴承的运行过程中,会出现很多磨损颗粒与杂质,这将损坏轴承结构,降低轴承结构的使用寿命,另外,在轴承运行过程中会产生热量,尤其是在轴承使用在某些高温环境中时,轴承内部的温度会更高,过高的温度会加速润滑脂变质。
发明内容
本发明的目的是提供一种脂润滑轴承系统,以至少解决下列问题之一:现有技术中轴 承的运行过程,会出现很多磨损颗粒与杂质,损坏轴承结构,降低轴承结构的使用寿命的问题;轴承内部的温度较高,过高的温度会加速润滑脂变质的问题;不能及时获知轴承中润滑脂的状态,以及时的进行处理的问题,从而为脂润滑轴承系统的平稳运行提供有利条件。

具体实施方式
一种脂润滑轴承系统的实施例1,在图1、图2和图3中,本实施例中的轴承结构为滑动轴承,没有设置滚动体,外圈1和内圈2以及两端设置的油封形成一个润滑空间,润滑空间用于设置润滑油。在轴承结构的外圈1上开设有注油孔4、排油孔5以及呼吸口3,注油孔4、排油孔5以及呼吸口3均与润滑空间导通。在呼吸口3上设置有空气过滤装置。
在排油孔5上连通设置有润滑脂循环驱动装置,这里的润滑脂循环驱动装置为吸脂器7,如图3所示,吸脂器7具有壳体8,壳体8的内腔一端密封滑动设置有柱塞9,在壳体8的另一端端部开设有出脂口10,该出脂口10与壳体8的内腔连通,出脂口10与注油孔4连通,在壳体8靠近出脂口10的那个端头上一体设置有单向阀结构,单向阀结构与吸脂器7共用壳体,单向阀结构的阀芯11滑动装配在壳体8上,阀芯11与固定在壳体8的阀座12之间设置有复位簧13,阀芯11在复位簧13的作用下会将出脂口10封住,在壳体8上还具有一个转换口14,转换口14在阀芯11不同于出脂口10的另一侧与壳体8的内腔连通,也就是说,转换口14通过一个单向阀结构与出脂口10相连通,而注油孔4是直接与转换口14相连,也就是说出脂口10与注油孔4之间具有单向阀,并且单向阀允许油液由出脂口10流向注油孔4,在壳体8的侧壁上开设有吸脂口15,吸脂口15是与轴承结构的排油孔5连通的,柱塞9由动力装置驱动往复运动。本实施例中的动力装置为液压油缸,液压油缸也是集成在吸脂器7上的,也就是与吸脂器7共用同一个壳体,液压油缸的活塞22与柱塞9连接在一起,活塞22的直径大于柱塞9的直径,壳体8上开设与活塞配合的 进排油孔21。而液压油缸的动力泵17是独立的,不和任何设备结构共用,也就是说吸排装置具有独立的动力系统,动力泵17是由电机18驱动的。液压油缸与动力泵17之间设置有二位四通换向阀19。
在吸脂器7与注油孔4之间串设有润滑脂过滤装置20和冷却装置23,冷却装置23靠近吸脂器,润滑脂过滤装置20靠近注油孔4。
在注油孔4前还串设有两位三通阀24,两位三通阀24具有三个油口,其中两个油口用于串设的油路中,第三个油口上连接废油脂储存装置25。
在轴承结构上还开设有补油孔6,补油孔上连通设置有油脂供给装置,供油装置具有供油泵26的出油口连接有分配器16,分配器16的各个出口分别与补油孔6相连,为轴承结构补油。
在脂润滑轴承系统还设置有电控系统,电控系统能依据预先设定的工作间隔时间以及工作持续时间自动控制润滑脂循环驱动装置与油脂供给装置启动与停止。根据实际情况计算出工作间隔时间以及工作持续时间后,将这个时间输入到电控系统中即就可以实现这种控制,对本领域的技术人员来说不需要创造性劳动。
一种脂润滑轴承系统的实施例2,在图4中,本实施例与脂润滑轴承系统的实施例1的区别在于:本实施例的吸脂器柱塞是由电动推杆驱动的,电动推杆由电机18驱动。这里的电机18为直线电机,吸脂器的结构与实施例1中的吸脂器的结构相同。
上述实施例中设置了润滑脂过滤装置和冷却装置,在其他实施例中,也可以单独设置润滑脂过滤装置或冷却装置。
上述实施例中的脂润滑轴承系统的吸脂器也可以采用气压缸驱动,气压缸与液压缸属于等同技术特征。
上述实施例中的冷却装置23靠近吸脂器,润滑脂过滤装置20靠近注油孔4,在其他实施例中,冷却装置23与润滑脂过滤装置的位置可以互换。
上述实施例中驱动电动推杆的电机为直线电机,在其他实施例中也可以是普通电机,通过螺旋传动,把旋转运动转换为直线运动。
一种脂润滑轴承系统的实施例3,在图5中,本实施例与脂润滑轴承系统的实施例1的区别在于:本实施例中,润滑脂循环驱动装置与注油孔之间除了串设有润滑脂过滤装置20、冷却装置23之外,还串设了油品检测装置27,油品检测装置可检测以下参数:水分含量、浑浊程度、热量和机械磨损、温度以及老化程度,其构成为现有技术,具体可见中国发明专利申请“CN105612413A”的说明书,或采用其它市售产品,此处不予赘述。本 实施例中,油品检测装置27设置在了润滑脂过滤装置20和冷却装置23之前(上游),作用是检测由轴承结构润滑空间从排油口排出的润滑脂的品质,以判断是否将其通过两位三通阀24排至废油脂储存装置25。
一种脂润滑轴承系统的实施例4,在图6中,本实施例与脂润滑轴承系统的实施例3的区别在于:本实施例中,油品检测装置27设置在了润滑脂过滤装置20和冷却装置23之后(下游),作用是检测经润滑脂过滤装置20和冷却装置23处理过的润滑脂的品质,以判断是否将其通过两位三通阀24排至废油脂储存装置25,同时,还可以判断与之相靠近的润滑脂过滤装置20的过滤效果,以为润滑脂过滤装置20的替换提供依据。
一种脂润滑轴承系统的实施例5,在图7中,本实施例与脂润滑轴承系统的实施例4的区别在于:本实施例中,去掉了润滑脂过滤装置,油品检测装置27可以用于判断与之相靠近的冷却装置23的冷却效果,以为冷却装置23的替换或调整提供依据。
一种脂润滑轴承系统的实施例6,在图8中,本实施例与脂润滑轴承系统的实施例3的区别在于:本实施例中,去掉了冷却装置,当然,在其他实施例中,还可以根据需要去掉润滑脂过滤装置20。
