Description

轴承废油脂自动收集系统及轴承自动换脂系统 技术领域
本发明涉及一种为轴承注入润滑脂并抽出轴承内的老化油脂的轴承自动换脂系统，本发明还涉及该轴承自动换脂系统的轴承废油脂自动收集系统。
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，用于风力发电设备、建筑机械等中的轴承就属于这类轴承，这类轴承需要采用油脂进行润滑，油脂的粘稠度较大，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，润滑脂也不会流出，但是，随着时间的流逝，润滑脂会老化，变硬，这就需要向润滑空间内注入新的油脂并替换旧的油脂，现有技术中会通过供油装置对轴承提供油脂，供油装置具有供油泵，供油泵一般为柱塞泵或者齿轮泵，供油泵连接块式分配器，分配器分别与各个轴承上的各个进油口连通。随着新鲜润滑脂的注入，老化后的旧油脂会被从开设在轴承结构上的出油口挤出，为了防止出来的旧油脂污染环境，会在出油口上设置油脂收集瓶，首先，定时排空这些有时很难接近的瓶子是很麻烦的。此外存在这样的风险，即如果瓶子没有及时排空，润滑脂便不受控制地从轴承结构中流出。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油脂，造成油脂收集瓶中没有收集到油脂，油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，为了解决这一问题，设计出来了抽吸装置，采用抽吸装置将旧油脂抽吸出来，在现有技术中，为了抽吸量与注入量之间的平衡，采用注入与抽吸之间的互锁，也就是，注入装置与抽吸装置的动力是一个，同时启动并同时停止，以此保证抽吸与注入之间的平衡，但是，这种简单的互锁很难平衡抽吸与注入之间的关系，因为如果轴承内部没有了润滑脂会造成巨大的损失，所以为了确保轴承结构内部存有一定的润滑脂，抽吸装置的抽吸量一般都设置的稍微小，再加上旧油脂的粘稠度较大，会存在一定的抽空量，这就造成了，抽吸量不够，而导致旧油脂积压的问题，这样一来，轴承结构内部的压力会过大，日久天长就会破坏轴承结构。同时，就算是知道轴承结构内部的压力过大，也无法抽吸旧油脂。

具体实施方式
一种轴承废油脂自动收集系统的实施例1，在图1、图5以及图7中，结合图2，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脂。在轴承结构的外圈1上开设有进油口4、出油口5以及呼吸口3，进油口4、出油口5以及呼吸口3均与润滑空间导通。进油口4是均匀设置在轴承结构上的，在相邻的两个进油口4之间设置有出油口5或者呼吸口3，处在一个进油口4两侧的一个是出油口，另一个是呼吸口3。在呼吸口3上设置有空气过滤装置。
在出油口5上连通设置有吸排装置，这里的吸排装置为吸脂器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排油口10，该排油口10与壳体8的内腔连通，排油口10是用于连通废油储存装置的，在本实施例的附图中没有画出废油储存装置，废油储存装置可以是废油桶，只要具有废油存储空间即可。在壳体8靠近排油口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的作用下会将排油口10封住，在壳体8上还具有一个转换口，转换口在阀芯11不同于排油口的另一侧与壳体8的内腔连通，也就是说，转换口通过一个单向阀结构与排油口相连通，而废油储存装置直接与转换口相连，也就是说排油口与废油储存装置之间具有单向阀，并且单向阀允许油液由排油口流向废油储存装置，在吸脂器的排油口和废油储存装置间还串设有过滤装置，因为转换口的存在，过滤装置是直接设置在转换口与废油储存装置之间的。过滤装置用于在线观察废油脂内的杂质含量，也就是在过滤装置上可连接上油脂检测装置，油脂检测装置是一种在线的油脂检测系统，检测参数包括油脂的杂质含量、铁等金属元素含量，为一种现有技术。在壳体8的侧壁上开设有吸油口15，吸油口15是与轴承结构的出油口连通的，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出油口21。而液压油缸的动力泵19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，动力泵是由电机驱动的。
在轴承结构的润滑空间内还设有压力传感器，如图5所示，该压力传感器为CYYZ51平模型压力变送器，压力传感器会将检测到的压力信号传递给中央控制器，这里的中央控制器为单片机，如图7所示，中央控制器能将接收到的压力信号与预先存入其内的设定压力进行比较，中央控制器控制吸排装置的动力系统开启或停止。由于CYYZ51平模型压力变送器输出的是485信号，需要对该信号进行变换，这是一种标准变换。图5即为压力传感器的485信号变换电气图，经过变换后的结构与单片机上对应的接头进行连接即可，也就是图5中的485_RX、485_CON、485_TX接口与图7中单片机上的485_RX、485_CON、485_TX对应相连。单片机是通过继电器来控制电机的，这也是一种常规的控制方式，图8即为控制电路，其中的电机端子分别与电机的正负极连接，其Relay_Z与Relay_F的控制信号分别与单片机的Relay_Z与Relay_F端口相连，而单片机的功能则通过编程来实现，让其具有将接收到的压力信号与预先存入其内的设定压力进行比较，根据结果控制吸排装置的动力系统开启或停止的功能。当单片机接收到压力大于其内设的压力时，控制吸排装置的动力系统开启，反之控制吸排装置的动力系统停止。

在轴承结构的润滑空间内还设有压力传感器，如图5所述，该压力传感器为CYYZ51平模型压力变送器，压力传感器会将检测到的压力信号传递给中央控制器，这里的中央控制器为单片机，如图7所示，中央控制器能将接收到的压力信号与预先存入其内的设定压力进行比较，中央控制器控制吸排装置的动力系统开启或停止。由于CYYZ51平模型压力变送器输出的是485信号主控系统，需要对该信号进行变换，这是一种标准变换。图5即 为压力传感器的485信号变换电气图，经过变换后的结构与单片机上对应的接头进行连即可，也就是图5中的485_RX、485_CON、485_TX信号与图7中单片机上的485_RX、485_CON、485_TX对应相连。单片机是通过继电器来控制电机的，这也是一种常规的控制方式，图8即为控制电路，其中的电机端子分别与电机的正负极连接，其Relay_Z与Relay_F信号分别与单片机的Relay_Z与Relay_F端口相连，而单片机的功能则通过编程来实现，让其具有将接收到的压力信号与预先存入其内的设定压力进行比较，根据结构控制吸排装置的动力系统开启或停止的功能。当单片机接收到压力大于其内设的压力时，控制吸排装置的动力系统开启，反之控制吸排装置的动力系统停止。
