Description
Technical Field
The utility model relates to a marine part especially relates to a marine rudderstock.
Background
The rudder stock is a shaft for rotating the rudder blade and is used for bearing and transmitting force acting on the rudder blade and force of the rudder for turning the rudder device, namely the rudder blade is rotated by the rudder stock, and the rudder blade bearing reacting force on the rudder blade to steer the ship.
The rudder stock is a structure used for fixing and rotating rudder blades, when a ship turns, pressure on the rudder blades is completely borne by the rudder stock, a main stressed position of a suspended rudder is located at a contact position of the rudder stock and a rudder bearing, the section size of the rudder stock at the position needs to meet the requirement of ship building specifications, and the rudder stock is usually made of metal cylinders or round tubes with equal sectional areas.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above problem and provide a simple structure, rapid Assembly, light in weight, job stabilization, reduction water flow resistance, firm in connection, waterproof anticorrosive marine rudderstock.
The technical scheme of the utility model is that: the utility model provides a marine rudderstock, the rudder include rudderstock, rudder cover, paddle and rudder pintle, rudder stock middle part pass through rudder pintle and paddle fixed connection, the rudder cover set up on the rudderstock, the rudder stock lower part set up in the paddle, the paddle on be equipped with multichannel strengthening rib and a plurality of drainage hole.
Furthermore, one side of the upper end of each blade is in an arrow shape, so that the resistance of water flow is reduced; one side edge of the paddle is linear, so that the contact between the edge of the paddle and water flow is facilitated, and the water flow resistance is reduced; the lower end of the paddle is arc-shaped, so that water flow is gathered during rotation, and the propelling force is increased.
Furthermore, eight reinforcing ribs are symmetrically distributed on the front face and the back face of the paddle, eight grooves are symmetrically distributed on the front face and the back face of the paddle, the reinforcing ribs are respectively arranged in the grooves, the surfaces of the reinforcing ribs are lower than the surfaces of the paddle, and when the paddle rotates, the reinforcing ribs are in contact with water flow, so that the resistance of the water flow cannot be increased.
Furthermore, circular drainage holes are formed among the reinforcing ribs on the surface of the paddle, so that the flow speed between water flow and the paddle is increased.
The utility model has the advantages that: waterproof glue is arranged on the outer side of the pin bush to connect and fix the insertion hole and the pin bush, and the position of the bayonet lock is fixed through a waterproof bolt; one side of the upper end of each paddle is in an arrow shape, so that the resistance of water flow is reduced; one side edge of the paddle is linear, so that the contact between the edge of the paddle and water flow is facilitated, and the water flow resistance is reduced; the lower end of the paddle is arc-shaped, so that water flow is favorably gathered during rotation, and the propelling force is increased; the surface of the reinforcing rib is lower than the surface of the paddle, and when the paddle rotates, the reinforcing rib is contacted with water flow, so that the resistance of the water flow cannot be increased; one part of the reinforcing ribs is vertically connected with the rudder stock, and the other part of the reinforcing ribs is obliquely and crossly connected with the rudder stock, so that the strength of the paddle is improved; the circular drainage holes accelerate the flow velocity between water flow and the blades.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a rudder stock main body, 2 is a rudder sleeve, 3 is a blade, 4 is a bayonet lock, 5 is a reinforcing rib, 6 is a drainage hole, 7 is a pin sleeve, and 8 is a threaded hole.
Detailed Description
The utility model provides a marine rudderstock, the rudderstock include rudderstock main part 1, rudder cover 2, paddle 3, rudder cover 2 set up on rudderstock main part 1, 1 lower part of rudderstock main part set up in paddle 3, paddle 3 on be equipped with multichannel strengthening rib 5 and a plurality of drainage hole 6, 1 inside bayonet lock 4 that is equipped with of rudderstock main part and extend 1 lower part of rudderstock main part, 3 upper ends of paddle be equipped with the inserted hole, the inserted hole in be equipped with cotter 7, 7 outsides of cotter be equipped with waterproof glue and be connected fixedly with inserted hole and cotter 7, 7 surfaces of cotter be equipped with a plurality of screw holes 8, bayonet lock 4 insert in the cotter 7 and through the position of waterproof bolt fixed bayonet lock 4.
One side of the upper end of the paddle 3 is in an arrow shape, so that the resistance of water flow is reduced; one side edge of the paddle 3 is linear, so that the contact between the edge of the paddle 3 and water flow is facilitated, and the water flow resistance is reduced; the lower end of the paddle 3 is arc-shaped, so that water flow is gathered during rotation, and the propelling force is increased.
The reinforcing ribs 5 are symmetrically distributed on the front surface and the back surface of the paddle 3, eight grooves are symmetrically distributed on the front surface and the back surface of the paddle 3, the reinforcing ribs 5 are respectively arranged in the grooves, the surfaces of the reinforcing ribs 5 are lower than the surfaces of the paddle 3, and when the paddle 3 rotates, the reinforcing ribs 5 cannot increase the resistance of water flow.
Circular drainage holes 6 are formed among the reinforcing ribs 5 on the surface of the paddle 3, so that the flow speed between water flow and the paddle 3 is increased.
