The casing includes a left side panel, a bottom panel, a right side panel, a top panel, a right neutral panel and a left neutral panel. The left panel, the left neutral panel, the right neutral panel and the right panel are arranged from left to right, and they are all longitudinally and vertically arranged. Both the top plate and the bottom plate are arranged horizontally. The driving gear and the driven gear mesh with each other, and they are installed between the left neutral plate and the right neutral plate.

本发明一种带导轮的外齿啮合双桨船舶推进器是这样产生有益效果的：右带齿环形平板桨叶是这样工作的：起初，右带齿环形平板桨叶处于纵向最前位置，即右带齿环形平板桨叶的后端内壁紧贴右定位杆的后缘，右带齿环形平板桨叶的前端处于最前端，右带齿环形平板桨叶的左侧面紧贴壳体的右中立板的右侧面，驱动本推进器的动力从主轴输入，从上往下俯视本推进器，主动齿轮逆时针旋转，带动右带齿环形平板桨叶在壳体的右半部分内作半圆周运动，即右带齿环形平板桨叶在纵向最前位置绕右定位杆转动半周后到达纵向最后位置，然后直线前行至纵向最前位置，接下来右带齿环形平板桨叶又绕右定位杆顺时针转动半周，然后又直线前行至纵向最前位置，即回到了起初位置。接下来周期性地重复上述过程。这样，右带齿环形平板桨叶会连续不断地将前方的水引进壳体内然后划向后方，产生向前的推力。运动过程中，右带齿环形平板桨叶在前面与壳体的右中立板之间快速打开而在后面与右中立板之间快速合上，产生了类似昆虫的“急张”和“相扑”运动效果，而且由于壳体的限制，右带齿环形平板桨叶在壳体内运动还产生了镜面效果，能产生很大的推力。由于右导轨的限制，右导轮只能沿右导轨外周运动，右带齿环形平板桨叶能作很标准的半圆周运动。同理，左带齿环形平板桨叶在从动齿轮的带动下作逆时针半圆周运动，左带齿环形平板桨叶的运动与右带齿环形平板桨叶的运动是对称的。左带齿环形平板桨叶和右带齿环形平板桨叶同时反向运动会相互抵消扭矩，使得本发明推进器运行平稳。控制尾部的方向舵的偏转方便船舶转弯。本发明推进器包括但不限于以下优点：能量损失小，效率高，运行平稳，桨叶低转速时可产生高推力，噪音小，且叶片易制作，不会像螺旋桨推进器那样产生明显的尾迹，也不会像传统明轮推进器那样存在严重的拍水现象。A kind of external gear meshing double paddle ship propeller with guide wheel of the present invention produces beneficial effect like this: the right toothed annular flat paddle works like this: at first, the right band toothed annular flat paddle is in the longitudinal most forward position, that is The inner wall of the rear end of the right toothed annular flat paddle is close to the rear edge of the right positioning rod, the front end of the right toothed annular flat paddle is at the forefront, and the left side of the right toothed annular flat paddle is close to the right side of the shell. On the right side of the neutral plate, the power to drive the propeller is input from the main shaft. Looking down at the propeller from above, the driving gear rotates counterclockwise, driving the right toothed annular flat blade to form a semicircle in the right half of the shell. Circular movement, that is, the right toothed annular flat blade rotates half a circle around the right positioning rod at the longitudinal front position and reaches the longitudinal final position, then moves straight forward to the longitudinal front position, and then the right toothed annular flat blade rotates around the right positioning rod Turn clockwise for half a circle, and then go straight ahead to the longitudinal frontmost position, that is, get back to the original position. Next, the above process is repeated periodically. In this way, the right toothed annular plate paddle can continuously introduce the water in the front into the housing and then draw it to the rear to generate forward thrust. During the movement, the right toothed annular flat paddle quickly opens between the front and the right neutral plate of the shell and quickly closes between the rear and the right neutral plate, resulting in insect-like "jitter" and "sumo wrestling" "Motion effect, and due to the limitation of the shell, the movement of the right toothed annular flat plate blade in the shell also produces a mirror effect, which can generate a lot of thrust. Due to the limitation of the right guide rail, the right guide wheel can only move along the outer circumference of the right guide rail, and the right toothed annular flat paddle can move in a very standard semicircle. In the same way, the left toothed annular flat paddle moves counterclockwise in a half circle under the drive of the driven gear, and the motion of the left toothed annular flat paddle is symmetrical to that of the right toothed annular flat paddle. The simultaneous reverse movement of the left toothed annular flat plate blade and the right toothed annular flat plate blade can cancel each other out torque, so that the propeller of the present invention operates smoothly. Controlling the deflection of the rudder at the tail facilitates the turning of the ship. The propeller of the present invention includes but is not limited to the following advantages: small energy loss, high efficiency, stable operation, high thrust when the blade rotates at a low speed, low noise, and the blade is easy to manufacture, and does not produce obvious wakes like propeller propellers , and there will be no serious splashing of water like traditional paddle wheel propellers.
为使本发明推进器的效率较高，右带齿环形平板桨叶和左带齿环形平板桨叶的高宽比的比值在0.6~3之间。In order to make the propeller of the present invention have higher efficiency, the aspect ratio of the right toothed annular flat blade and the left toothed annular flat blade is between 0.6 and 3.
为减少左带齿环形平板桨叶和右带齿环形平板桨叶在壳体中运动时它们的底部与壳体的底板的上表面之间的摩擦，左带齿环形平板桨叶和右带齿环形平板桨叶的底部镶有减摩滚珠，或者在左定位杆和右定位杆上分别套一个耐磨平垫片，两个耐磨平垫片位于壳体的底板的上表面上并分别垫于左带齿环形平板桨叶和右带齿环形平板桨叶的底部；左带齿环形平板桨叶和右带齿环形平板桨叶的密度稍大于水的密度，密度范围在1050~1400kg/m3之间。In order to reduce the friction between the bottom of the left toothed annular flat paddle and the right toothed annular flat paddle when they move in the casing and the upper surface of the bottom plate of the casing, the left toothed annular flat paddle and the right toothed flat paddle The bottom of the ring-shaped flat paddle is inlaid with anti-friction balls, or a wear-resistant flat gasket is respectively set on the left positioning rod and the right positioning rod, and the two wear-resistant flat gaskets are located on the upper surface of the bottom plate of the housing and respectively At the bottom of the left toothed annular flat blade and the right toothed annular flat blade; the density of the left toothed annular flat blade and the right toothed annular flat blade is slightly greater than the density of water, and the density ranges from 1050 to 1400kg/m between 3 .
为了能达到高效节能，推进器的结构应设计紧凑，右侧板的左侧面位于右带齿环形平板桨叶的齿的位置开有一条水平方向的槽，右带齿环形平板桨叶的齿在该槽中经过；左侧板的右侧面位于左带齿环形平板桨叶的齿的位置也开有一条水平方向的槽，左带齿环形平板桨叶的齿在该槽中经过。右带齿环形平板桨叶除齿之外的宽度稍小于壳体的右中立板的右侧面到右侧板的左侧面之间的距离；左带齿环形平板桨叶除齿之外的宽度稍小于壳体的左中立板的左侧面到左侧板的右侧面之间的距离。左带齿环形平板桨叶和右带齿环形平板桨叶的高度相同，它们的高度稍小于左导轨的下表面到底板的上表面之间的距离。In order to achieve high efficiency and energy saving, the structure of the propeller should be designed compactly. There is a horizontal groove on the left side of the right plate at the position of the teeth of the right toothed annular flat blade, and the teeth of the right toothed annular flat blade Pass through in this groove; The right side of left side plate is positioned at the position of the tooth of left toothed annular flat blade also has a groove in horizontal direction, and the tooth of left toothed annular flat blade passes in this groove. The width of the right toothed annular flat blade except the teeth is slightly smaller than the distance between the right side of the right neutral plate of the housing and the left side of the right side plate; the left toothed annular flat blade except the teeth The width is slightly smaller than the distance between the left side of the left neutral plate of the casing and the right side of the left side plate. The height of the left toothed annular flat paddle and the right toothed annular flat paddle is the same, and their height is slightly smaller than the distance between the upper surface of the bottom surface of the left guide rail and the bottom plate.

本发明推进器是这样工作的：右带齿环形平板桨叶5是这样工作的，起初，右带齿环形平板桨叶5处于纵向最前位置，即右带齿环形平板桨叶5的后端内壁紧贴右定位杆3的后缘，右带齿环形平板桨叶5的前端处于最前端，右带齿环形平板桨叶5的左侧面紧贴壳体7的右中立板75的右侧面，驱动本推进器的动力从主轴1输入，从上往下俯视本推进器，主动齿轮11逆时针旋转，带动右带齿环形平板桨叶5在壳体7的右半部分内作半圆周运动，即右带齿环形平板桨叶5在纵向最前位置绕右定位杆3转动半周后到达纵向最后位置，然后直线前行至纵向最前位置，接下来右带齿环形平板桨叶5又绕右定位杆3顺时针转动半周，然后又直线前行至纵向最前位置，即回到了起初位置。接下来周期性地重复上述过程。这样，右带齿环形平板桨叶5会连续不断地将前方的水引进壳体7内然后划向后方，产生向前的推力。运动过程中，右带齿环形平板桨叶5在前面与壳体7的右中立板75之间快速打开而在后面与右中立板75之间快速合上，产生了类似昆虫的“急张”和“相扑”运动效果，而且由于壳体7的限制，右带齿环形平板桨叶5在壳体7内运动还产生了镜面效果，能产生很大的推力。由于右导轨81的限制，右导轮91只能沿右导轨81外周运动，右带齿环形平板桨叶5能作很标准的半圆周运动。同理，左带齿环形平板桨叶6在从动齿轮21的带动下作逆时针半圆周运动，左带齿环形平板桨叶6的运动与右带齿环形平板桨叶5的运动是对称的。左带齿环形平板桨叶6和右带齿环形平板桨叶5同时反向运动会相互抵消扭矩，使得本发明推进器运行平稳。控制尾部的方向舵10的偏转方便船舶转弯。The propeller of the present invention works like this: the right toothed annular flat paddle 5 works like this, at first, the right toothed annular flat paddle 5 is in the longitudinal frontmost position, that is, the rear end inner wall of the right toothed annular flat paddle 5 Close to the rear edge of the right positioning rod 3, the front end of the right toothed annular flat paddle 5 is at the front end, and the left side of the right toothed annular flat paddle 5 is close to the right side of the right neutral plate 75 of the housing 7 , the power to drive the propeller is input from the main shaft 1, looking down at the propeller from top to bottom, the driving gear 11 rotates counterclockwise, driving the right toothed annular flat paddle 5 to make a semi-circular motion in the right half of the housing 7 , that is, the right toothed annular flat paddle 5 rotates half a circle around the right positioning rod 3 at the longitudinal front position and reaches the longitudinal final position, then moves straight ahead to the longitudinal front position, and then the right toothed annular flat paddle 5 is positioned around the right The bar 3 rotates half a circle clockwise, and then moves straight forward to the longitudinal frontmost position, that is, it returns to the original position. Next, the above process is repeated periodically. In this way, the right toothed annular plate paddle 5 can continuously introduce the water in the front into the housing 7 and then draw it to the rear to generate forward thrust. During the movement, the right toothed annular flat paddle 5 quickly opens between the front and the right neutral plate 75 of the housing 7 and quickly closes between the rear and the right neutral plate 75, producing a “snap” similar to insects And "sumo" movement effect, and because of the limitation of housing 7, the movement of right toothed annular flat paddle 5 in housing 7 also produces mirror effect, which can produce very large thrust. Due to the limitation of the right guide rail 81, the right guide wheel 91 can only move along the right guide rail 81 periphery, and the right toothed annular plate paddle 5 can do very standard semi-circular motion. In the same way, the left toothed annular flat paddle 6 is driven by the driven gear 21 to move counterclockwise in a half circle, and the motion of the left toothed annular flat paddle 6 is symmetrical to that of the right toothed annular flat paddle 5 . The simultaneous reverse movement of the left toothed annular flat paddle 6 and the right toothed annular flat paddle 5 can cancel out the torque, so that the propeller of the present invention operates smoothly. Control the deflection of the rudder 10 at the tail to facilitate the turning of the ship.
