Abstract
A ship clutch module according to an embodiment of the present invention is a clutch module for transmitting a driving force of an engine of a ship to a propeller. The ship clutch module includes a shaft having an engaging portion which is connected to a shaft of the engine, A second rotation axis for transmitting the driving force of the engine to the propeller, a first rotation shaft, a first rotation shaft, and a second rotation shaft, the first rotation shaft being inserted into the engagement groove portion formed in the radial direction, And a coupling gear for selectively connecting the first rotation shaft and the second rotation shaft.
Description
The present invention relates to a ship clutch module for transmitting a driving force of an engine of a ship to a propeller.
In a pair of axles, each of which is equipped with a propeller for each of the two engines, only one propeller is actually operated.
In this case, when only one propulsion unit is to be operated, a propulsion unit that is not normally operated may be left stationary with the main engine connected, but the propulsion unit can be rotated The resistance performance is improved and the overall efficiency can be increased.
However, in the structure in which the propeller is connected to the main engine in the conventional biaxial line, the first rotary shaft coupled to the main engine is rotatably inserted in the hollow shaft of the second rotary shaft connected to the propeller, And the first rotary shaft and the second rotary shaft are selectively rotatably coupled together by a coupling gear.
In this case, when the main engine is not operated, the coupling gear is released to prevent the first rotation shaft and the second rotation shaft from rotating together. In this way, the first rotation shaft and the second rotation shaft are not rotated together The second rotary shaft of the propeller is rotated relative to the first rotary shaft, so that severe friction occurs in the bearing and the bearing is damaged.
The present invention provides a ship clutch module capable of rotating the first rotation axis and the second rotation axis more efficiently while concentrating the first rotation axis and the second rotation axis when the first rotation axis and the second rotation axis are connected to each other I want to.
A ship clutch module according to an embodiment of the present invention is a clutch module for transmitting a driving force of an engine of a ship to a propeller. The ship clutch module includes a shaft having an engaging portion which is connected to a shaft of the engine, A second rotation axis for transmitting the driving force of the engine to the propeller, a first rotation shaft, a first rotation shaft, and a second rotation shaft, the first rotation shaft being inserted into the engagement groove portion formed in the radial direction, And a coupling gear for selectively connecting the first rotation shaft and the second rotation shaft.
Further, the coupling gear may be configured such that, when the first rotation shaft and the second rotation shaft are connected to each other, the coupling gear is protruded toward the central axis of the first rotation shaft, and is supported by the first rotation shaft, And may include protrusions that are connected to coincide with the central axis.
The first rotation shaft may include a gear portion connected to the coupling gear and having gears for transmitting a driving force to the outside, and a seating portion formed to have a diameter smaller than that of the gear portion and seated on the outer side of the coupling portion. Wherein a center of a second rotary part connected to the coupling gear is coincident with a center of the first rotary part while the protruding part moves along the cheek part when the coupling gear moves to the gear part, .
And the end of the protrusion can be inclined to correspond to the slanting portion tapered.
The first rotation axis and the second rotation axis may be connected to each other while forming a spacing space in a radial direction.
In addition, a shaft bearing installed axially on both sides of the engaging portion may be included.
In addition, the outer side of the shaft may include a first radial bearing for supporting the shaft in a radial direction.
The second rotary shaft may include a second radial bearing that supports the second rotary shaft in a radial direction.
In addition, a third radial bearing may be provided at an end of the first rotation shaft to support the second rotation shaft in a radial direction.
According to an embodiment of the present invention, when the second rotary shaft is connected to the first rotary shaft, the second rotary shaft may be connected to the first rotary shaft while being concentric with the first rotary shaft. Thus, when the driving force of the engine is transmitted to the second rotational shaft connected to the propeller by the first rotational shaft, the driving force of the engine can be transmitted to the propeller without loss.
In addition, when the first rotation axis and the second rotation axis are separated from each other, the first rotation axis and the second rotation axis can be prevented from being damaged due to the relative rotation between the first rotation axis and the second rotation axis.
