具体实施方式
为使本公开解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面结合附图并通过具体实施方式来进一步说明本公开的技术方案。可以理解的是，此处所描述的具体实施例仅仅用于解释本公开，而非对本公开的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本公开相关的部分而非全部。
如图1所示，本实施例提供了一种风力助推装置，应用于船舶。该风力助推装置包括能够绕自身轴线转动的外筒1及设于其内的内塔2、转盘4和主轴3，转盘4位于内塔2顶部的盖板21上方，主轴3的下端伸入内塔2且 与内塔2转动连接，其上端通过转盘4与外筒1相连。其中，转盘4的上方设有与其相连的连接架5，主轴3的上端穿过转盘4且与连接架5相连，转盘4与主轴3固连，并通过法兰与外筒1固连。主轴3转动，将会带动转盘4和外筒1同步相对于内塔2转动。
随着船舶的运行，上述风力助推装置工作的过程中，外筒1外产生晃动，以致转盘4产生偏心，导致转盘4所在的主轴3产生较大的交变载荷。为此，本实施例提供的风力助推装置还包括多个辅助支撑组件6，多个辅助支撑组件6均设于内塔2顶部的盖板21和转盘4之间，且沿主轴3的周向分布，每个辅助支撑组件6的一端与内塔2顶部的盖板21和转盘4中的一个相连，另一端能够与另一个滚动连接。优选地，每个辅助支撑组件6的下端连接于内塔2顶部的盖板21，其上端与转盘4滚动连接。采用该设置可以排除制造、装配误差引起的平衡问题。
本实施例以设置八个辅助支撑组件6为例，八个辅助支撑组件6沿主轴3的周向均匀分布。本实施例提供的风力助推装置，外筒1转动的过程中，辅助支撑组件6将会接触转盘4，通过主轴3对外筒1进行支撑的同时，再通过多个辅助支撑组件6对转盘4进行支撑，以承受外筒1转动过程中各个方向的横向力，保证外筒1转动过程中的平稳性，从而降低外筒1的横向晃动，避免主轴3产生较大的交变载荷，延长了主轴3的使用寿命，降低了维护成本；同时由于辅助支撑组件6与转盘4或内塔2顶部的盖板21滚动连接，不会增加转动惯量，进而也不会增加能耗。
如图2和图3所示，上述辅助支撑组件6包括支架62、连接轴63和套筒641，其中，支架62上设有与其转动连接且能够接触转盘4的滚轮61，具体地，滚轮61的中心轴线水平设置，滚轮61相对于支架62绕其中心轴线转动。优选地，上述滚轮61采用轴承和聚氨酯制成的外圈组合的结构，减小了滚轮61的直接磨损，安装和维修方便。需要说明书的是由轴承和聚氨酯制成的外圈组合构成的滚轮61可以通过外购获取。
连接轴63的一端连接于支架62，另一端伸入套筒641内且转动连接于套筒641，套筒641连接于盖板21。具体地，套筒641的底部连接有安装座643，安装座643通过多个周向分布的紧固件如螺栓等连接于盖板21。连接轴63与支架62可以采用螺纹连接、卡接、焊接等方式连接。
在转盘4转动的过程中，滚轮61不仅可以绕其中心轴线转动，还可以随着连接轴63相对于盖板21转动，从而实现辅助支撑组件6与转盘4的滚动连接，减小转盘4转动的过程中，辅助支撑组件6与转盘4之间的摩擦力。
进一步地，转盘4上设有环形导向轨道，滚轮61的顶部置于环形导向轨道内，使滚轮61沿着环形轨道运转，以对滚轮61与转盘4之间的转动进行导向。
进一步地，套筒641内设有指向盖板21的第一阶梯面，连接轴63能够相对于套筒641轴向移动。上述风力助推装置还包括套设于连接轴63外的第一弹性件65及连接于连接轴63下端的限位件67，第一弹性件65夹设于第一阶梯面和限位件67之间。
船舶运行过程中不仅存在水平方向晃动，还存在竖直方向的晃动，转盘4不可避免会对滚轮61产生硬性冲击，为此本实施例通过第一弹性件65可以对连接轴63竖直方向的晃动进行缓冲，减小转盘4对滚轮61等结构件在竖直方向上的硬性冲击，减小滚轮61的磨损，延长风力助推装置的使用寿命。
优选地，上述限位件67为与连接轴63螺纹连接的螺母，通过旋拧螺母可以调节限位件67和第一阶梯面之间的距离，从而调节滚轮61对转盘4的支撑能力。
进一步地，套筒641内设有指向滚轮61的第二阶梯面，套筒641的顶部设有上端盖642，上端盖642和第二阶梯面之间夹设有第二弹性件66。通过第二弹性件66对风力助推装置在竖直方向产生的硬性冲击进行进一步的 缓冲，使缓冲距离可达2mm-3mm，从而进一步延长风力助推装置的使用寿命。本实施例中，上端盖642通过多个周向布设的螺栓连接于套筒641的顶部。
进一步地，为了使滚轮61的转动更加灵活，本实施例提供的风力助推装置还包括套设于连接轴63外且设于套筒641内的轴承68，使连接轴63转动连接于套筒641。优选地，上述轴承68设有两个，两个连接轴63设于套筒641的两端。具体其中一个轴承68设于第一弹性件65和第一阶梯面之间，另一个轴承68设于第二弹性件66和第二阶梯面之间。优选地，上述轴承68采用推力轴承，以避免连接轴63的转动出现卡死现象，从而使滚轮61转动的更加灵活。
显然，本公开的上述实施例仅仅是为了清楚说明本公开所作的举例，而并非是对本公开的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本公开的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本公开权利要求的保护范围之内。
