Description

一种桨本体和具有该桨本体的螺旋桨
技术领域
本发明涉及一种桨本体和安装有该桨本体的螺旋桨。 背景技术
螺旋桨是指靠桨叶在空气中旋转，将发动机转动功率转化为推进力的装置，或有两 个或较多的叶与毂相连， 叶的向后一面为螺旋面或近似于螺旋面的一种船用推进器。 现 有技术中， 例如中国专利 CN102367064A (申请号为 ZL201110137505.9)《盘式螺旋桨》 提供一种盘式螺旋桨， 其包括桨叶、 转轴连接体、 转盘， 所述桨体均匀布置在所述转轴 连接体四周， 且所述桨体后方设有转盘， 所述转盘与所述转轴连接体固结， 且转盘表面 布满通孔。 又如中国专利 CN2753670Y (专利号为 ZL200420098175.2)《串联式螺旋桨推 进器》提供一种串联式螺旋奖推进器， 其结构是由旋转轴和螺旋桨构成， 特点是两个或 两个以上的螺旋桨串联固定在旋转轴上， 旋转轴则通过联轴器与动力输出轴相接， 根据 螺旋桨的数量， 可在旋转轴上架设合适数量的固定支撑。
但是， 上述两个专利中的螺旋桨， 其旋转都是靠转轴、 桨毂来传递旋转力矩， 这种 螺旋桨在工作时，其转轴承受着旋转产生的扭应力以及螺旋桨动作产生的推压和吸压应 力， 而转轴在水中转动过程中， 还容易被水草等杂物缠绕， 造成螺旋桨无法正常工作。 因此， 目前的带转轴结构的螺旋桨还存在上述缺陷， 需要做进一步的改进。 发明内容
本发明所要解决的第一个技术问题是针对上述现有技术现状而提供一种结构更为 简单、 紧凑的桨本体。
本发明所要解决的第二个技术问题是针对上述现有技术现状而提供一种具有上述 桨本体的工作更加可靠的螺旋桨。
本发明解决上述第一个技术问题所采用的技术方案为：一种桨本体，包括有桨榖和 连接在该桨榖上的多片桨叶， 其特征在于： 所述桨叶的外周成型有轮圈， 所述轮圈的外 周壁上形成有沿周向布置的轮齿， 所述桨榖的两端是圆锥流线形。
本发明解决上述第二个技术问题所采用的技术方案为： 一种螺旋桨， 其特征在于： 所述轮圈之外还套设有可相对于该轮圈转动的固定套筒架， 并且， 所述套筒架的周壁上 开设有可供所述轮圈的轮齿与外部的齿轮传动装置相啮合的槽孔。
作为方便安装和拆卸，优选，所述套筒架和所述轮圈之间可以通过轴承实现可转动 连接。
为了保证连接的稳定性和定位可靠性，作为优选，所述轮圈的外周壁成型有环形凸 条， 所述轮齿设置于所述凸条上； 所述的轴承包括有位于所述凸条一侧的前端轴承和位 于所述凸条另一侧的后端轴承。
为了延长轴承的使用寿命，作为优选，所述前端轴承和后端轴承分别为耐磨衬垫轴 承。
为了防尘， 并且起到美观的作用， 作为优选， 所述轮圈的端部还设置有与所述套筒 架固定相连的端盖。
为了防止机油泄漏， 并且保证连接的密封性， 作为优选， 所述轮圈与所述端盖之间 设置有第一密封圈。
作为进一步优选， 所述轮圈与所述套筒架之间设置有第二密封圈。
与现有技术相比， 本发明的优点在于： 取消了传统的转轴结构， 而是在桨叶之外成 型一轮圈， 使得桨叶的旋转力矩传递方法由转轴改为轮圈旋转的方式， 螺旋桨的旋转不 靠转轴而是靠轮圈上的齿轮啮合来带动桨叶旋转， 由此， 船舶的主机与螺旋桨之间可以 不用机械转轴硬接， 为船舶提供了无转轴推进装置， 解决了大型船舶的转轴技术问题， 能让船舶的机舱设计更加灵活； 另外， 由于采用了齿轮啮合方式带动桨叶旋转， 同样功 率下， 螺旋桨电机的输出功率可以大大缩小， 不仅提高了船舶的工作效率， 更加降低了 能耗， 从而实现了节能。 附图说明
图 1为本发明实施例的结构示意图之一 (正面)。
图 2为本发明实施例的结构示意图之二 (背面)。
图 3为本发明实施例的立体剖视图。
图 4为本发明实施例的立体分解图。 具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图 1〜图 4所示， 本实施例的螺旋桨， 包括有桨榖 1和连接在该桨穀 1上的多片 桨叶 2;
其中， 桨叶 2的外周成型有轮圈 3， 该轮圈 3和桨叶 2的末端固定连接为一体， 桨 榖 1的两端是圆锥流线形， 轮圈 3的外周壁在中间位置成型有周向布置的环形凸条 31， 该凸条 31上形成有沿周向间隔设置的轮齿 32， 轮圈 3之外还套设有可相对于该轮圈 3 转动的套筒架 4， 套筒架 4通常为固定安装， 套筒架 4的周壁上还开设有一个可供轮圈 3的轮齿 32外露的槽孔 41，轮齿 32可以通过该槽孔 41与外部的齿轮传动装置相啮合， 从而驱动桨叶 2旋转。
本实施例中的套筒架 4和轮圈 3之间可以简单地通过轴承 5实现可转动连接，其中， 轴承 5布置于凸条 31的两侧， 并且分别沿轮圈 3周向布置， 轴承 5包括有位于凸条 31 一侧的前端轴承和位于凸条 31 另一侧的后端轴承， 为了延长使用寿命， 前端轴承和后 端轴承可以分别为耐磨衬垫轴承。
轮圈 3的端部设置有端盖 8， 该端盖 8沿周向通过螺钉 81与套筒架 4固定连接， 为防止漏油， 并实现密封， 轮圈 3与端盖 8之间设置有第一密封圈 6， 轮圈 3与套筒架 4之间则设置有第二密封圈 7， 套筒架 4和端盖 8之间则设置有密封圈 82。
工作时， 套筒架 4实现固定安装设置， 外部的传动装置通过套筒架 4上的槽孔 41 实现与轮圈 3上轮齿 32的齿轮啮合， 当外部的传动装置工作时， 通过齿轮啮合可以带 动轮圈 3转动， 由于轮圈 3与桨叶 2固定一体设计， 从而可以带动桨叶 2—起旋转。 本实施例取消了传统螺旋桨的转轴结构，将现有通过转轴的旋转力矩传递改变成为 通过轮圈 3带动桨叶 2旋转传递， 比较轮圈 3旋转与转轴力矩传递的效果， 依据杠杆的 力学平衡理论， 设定螺旋桨的桨穀 1中心为一个支点， 转轴的直径为杠杆一边的长度， 轮圈 3的外径为杠杆另一边的长度， 那么轮圈 3的外径与转轴的直径比值， 即为轮圈 3 的效果参数；
因此， 同一参数下的螺旋桨， 如果该螺旋桨实际需要 1万马力的轴功率时， 轮圈 3 驱动的螺旋桨的电机输出功率至少可以缩小至 4千马力至 1千马力之间， 甚至于更小。
于是， 当一台螺旋桨需要 1万马力轴功率主机时，其可以只用二千马力的主机带动 发电机， 再经发电机带动螺旋桨旋转， 从而大大地提高了船舶的能源效率， 实现节能降 耗。 另外， 采用本实施例的螺旋桨结构， 由于船舶的主机与螺旋桨之间可以不用机械转 轴硬接， 可以为船舶提供无转轴的推进装置， 使得船舶的机舱设计更加灵活。
