Abstract
The utility model discloses a yacht power device with an I-shaped propeller shaft bracket and relates to the field of yacht manufacture. The yacht power device comprises a propeller shaft extending out of a hull from an engine, the I-shaped propeller shaft bracket for fixing the propeller shaft, a propeller fixed on the propeller shaft, a rudder installed at the tail end of the hull and a diversion groove. The I-shaped propeller shaft bracket comprises a supporting column, a shaft hub and an empennage, wherein the top end of the supporting column is fixed on the hull, the lower end of the supporting column is connected with the shaft hub, the propeller shaft is installed in the shaft hub, the lower end of the shaft hub is connected with the empennage, and the empennage is perpendicular to the hull. The yacht power device has the advantages that by arranging the empennage on the I-shaped propeller shaft bracket, the stability of a yacht in running is improved, vibration of the propeller and the propeller shaft in the rotating process is reduced, and improvement of the propeller efficiency is facilitated; meanwhile the empennage of the I-shaped propeller shaft bracket can prevent fishing nets and ropes from being wound into the propeller, and the improvement of the reliability of the power device is facilitated.
Description
Technical field
The utility model relates to yacht and manufactures field, relates in particular to the yacht engine installation with I type shaft bracket.
Background technology
Existing private yacht particularly glass reinforced plastic yacht mostly is 30 meters of following high-speed boats, the revolution ratio of main frame is higher, to the transmission of stern tube shaft and screw propeller, require high, I type shaft bracket need to have certain survival space with yacht after plating and screw propeller could be installed, and the situation that easily produces fishing net, restricts and be wound around.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of yacht engine installation with I type shaft bracket, can improve the stability of hull.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of yacht engine installation with I type shaft bracket is provided, comprise the stern tube shaft that stretches out hull from driving engine, I type shaft bracket for fixing described stern tube shaft, the rudder and the flame diversion trough that are fixed on the screw propeller on stern tube shaft and are installed on hull end, described I type shaft bracket comprises pillar, propeller boss and empennage, the top of described pillar is fixed on hull, the lower end of pillar is connected with described propeller boss, described stern tube shaft is housed in propeller boss, propeller boss lower end is connected with described empennage, described empennage is vertical with hull.
Wherein, described empennage has the profile of following shape, its one side towards hull afterbody is linear edge, towards one side of fore-body, from top to bottom, is edge closed with described linear edge respectively by the curve of an indent and the curve combination of an evagination.
Wherein, described empennage is one-body molded that fine copper is cast.
The beneficial effects of the utility model are: by empennage being set on I type shaft bracket to improve the stability of yacht when moving, reduce screw propeller, the vibration of stern tube shaft in rotation process, be conducive to improve propeller efficiency; And the empennage of I type shaft bracket plays the effect that stops that fishnet, rope enter screw propeller simultaneously, be conducive to improve the reliability of engine installation.
Accompanying drawing explanation
