SUBSTANCE: invention relates to ship building, namely, to a rotary flap column intended for installation on boats and serving to transmit the torque from the engine to the propeller shaft and to control the boat. Rotary flap column for floating facilities includes a horizontal shaft, an upper conical reducer, a vertical shaft, a lower conical reducer and a screw propeller. Lifting mechanism used is a hydraulic cylinder, which is located in the upper part of the column, as well as a cardan shaft and a mechanism of rotation are present, due to which the column body rotates at any angle without a limitation within 360° and provides operation of the ship at astern running without changing rotation of the drive shaft. Column rotation mechanism includes an external stationary housing and a rigidly fixed to it through the upper and the lower bearings internal rotary housing. Rotation mechanism drive is fixed ontop the upper part of the external, stationary housing of the column, and via a gear transmits the rotation force onto a gear, which is rigidly connected with an inner cage of the upper bearing.

Description

Technical field

The invention relates to shipbuilding, and in particular to structures of a tilt-and-turn column, designed for installation on boats and serving to transmit torque from the engine to the propeller shaft and control the boat.

Known Patent RU 2219101 "Tilt-and-Swivel Column", which includes the upper and lower gears of the Z-shaped gear, deadwood, propeller shaft, propeller shaft reverse mechanism (wwwl.fips.ru, RU 2219101).

The disadvantages of this patent is that it does not allow the column to be rotated to the desired angle within 360 °, in addition, the folding device does not allow changing the angle of attack and, accordingly, the boat's trim.

Disclosure of the invention.

The technical result that is achieved from the use of the present invention is to create a rotary column that allows you to effectively control the boat, without rudders and with the same maximum thrust at all courses of the boat, providing the vessel in reverse without changing the rotation of the drive shaft, and also capable of changing angle of attack and, accordingly, the running trim of the boat.

The specified technical result is achieved by the fact that the tilt-and-turn column has a rotation mechanism, due to which the column body is rotated to any angle without restriction within 360 °, which ensures complete controllability of the vessel, optimal operation of the screw without changing its rotation in the opposite direction and the same maximum traction at any angles of movement.

The screw of the tilt-and-turn column is located below the bottom of the boat, which allows the hull of the column together with the screw to rotate 360 °, thereby ensuring the same optimal stop for the screw in any direction. When the column is turned through an angle of 180 ° or more degrees, the reverse gear of the boat is provided, as well as an emphasis on the reverse, the same as on the front, and the presence of greater controllability.

The claimed column lifting mechanism is located in the upper part of the column, which reduces the possibility of corrosion and simplifies its maintenance. The column lifting mechanism allows the column to be lifted out of the water, thereby changing the angle of attack and, accordingly, the boat's trim, and at maximum lifting, it ensures full column lifting and entry in shallow water.

The claimed column rotation mechanism comprises a rotation mechanism (2) mounted on top of the upper part of the external non-rotating column housing (4), which transfers the turning force to the gear (19), which is rigidly connected to the inner race of the upper bearing, through the drive gear of the rotation mechanism (6) (5).

The claimed column rotation mechanism also includes an upper bearing (16) and a lower bearing (17), the upper bearing (16) with an outer cage (9) attached to the inner surface of the upper part of the outer non-rotating casing of the column (4), and the inner cage (5) to the outer surface of the inner rotating column housing (10), the lower bearing (17) with the outer race (18) is attached to the inner surface of the lower part of the outer non-rotating column housing (15) and the inner race (20) is attached to the outer surface of the inner rotating shell column (10). As a result, the inner rotating casing of the column (10) is firmly fixed to the outer non-rotating casing in the upper (4) and lower (15) parts through two rotating bearings, the upper (16) and lower (17) spaced apart from friend.

The claimed column lifting mechanism consists of a hydraulic cylinder (1), fixed at one end from the top on the upper part of the outer non-rotating column body (4), and the second end with an arm (21), rigidly connected to the boat body (13). The driveshaft (8) allows the column to be lifted without damaging the shaft.

The implementation of the invention

At least one hinged-swivel column is located under the bottom of the boat in its stern.

To carry out the movement of the boat, the horizontal shaft of the column (7) transfers the force through the upper bevel gear (3) to the vertical shaft (14) and through the lower bevel gear (12) to the propeller (11).

To rotate the boat, the drive (2) of the rotation mechanism, mounted on top of the upper part of the outer non-rotating column housing (4), transfers the turning force to the gear (19) rigidly connected to the inner race of the upper bearing (5) through the gear (6), through which transmits a turning force to the inner rotating column housing (10) which rotates relative to the outer non-rotating column housing (4), (15), and the rotation occurs at any angle within 360 ° without any restriction. When the column is turned through an angle of 180 ° or more degrees, the boat is backed up.

When entering shallow water by means of a column lifting mechanism, namely a hydraulic cylinder (1), fixed at one end from the top on the top of the outer non-rotating column body (4), and at the other end with an arm (21), rigidly fixed to the boat body (13), and using the driveshaft (8), the column rises as much as possible from the water. In addition, the column lifting mechanism, lifting the column using the hydraulic cylinder (1) and the driveshaft (8) from the water, allows you to change the angle of attack and, accordingly, the boat's trim.

Due to the claimed invention is achieved the same, maximum thrust at all courses and at any angles of motion of the boat, because the screw rotates only in one direction, providing maximum traction. Due to the fact that the thrust of the screw can be directed in any direction, the absolute controllability of the boat is ensured. Due to the claimed lifting mechanism, it becomes possible to change the running trim of the boat.
