Abstract
Screw shaft of ship nominal endocentric phrase, comprise adapter plate, one end of riser is vertically fixedly mounted on the surface of adapter plate, and corresponding justify align on the two ends of the riser end face overlapping with adapter plate surface and adapter plate surface, is respectively arranged with assembly opening on the adapter plate surface of riser both sides.This kind of screw shaft of ship nominal endocentric phrase reduced artificial by the man-hour through the middle stern tube shaft of assaying, increase work efficiency, the stern tube shaft that ensures there is no front bearing precision in its axis fixed in water time, has further ensured the hard-cover of vessel motion direction, it is simple in structure, installation and easy to use.
Description
Technical field
The utility model relates to the nominal endocentric phrase of screw shaft of ship.
Background technology
Conventionally screw shaft of ship possesses two bearings, i.e. front bearing and rear bearing, the support by two bearings is with fixing, in case under the stern tube shaft completing in fastening after water its axis be offset.But, the stern tube shaft of some boats and ships only has rear bearing at present, and without front bearing, now, under the stern tube shaft having completed in fixed after water, because its front end does not have parts fixed pedestal, therefore, the axis of the stern tube shaft in water is easy to be offset, cause the service direction of boats and ships wrong, for solving stern tube shaft desaxe problem, in needing manually again determine the axis of stern tube shaft, but due to without any surely middle reference part, therefore, can only rely on artificial experience to determine middle stern tube shaft, this not only needs to expend a large amount of man-hours, also causes the service direction of boats and ships accurate not.
Utility model content
The utility model aims to provide a kind of screw shaft of ship nominal endocentric phrase that is easy to fixed middle stern tube shaft axis in water.
Screw shaft of ship nominal endocentric phrase described in the utility model, comprise adapter plate, one end of riser is vertically fixedly mounted on the surface of adapter plate, corresponding justify align on the two ends of the riser end face overlapping with adapter plate surface and adapter plate surface, is respectively arranged with assembly opening on the adapter plate surface of riser both sides.
Screw shaft of ship nominal endocentric phrase described in the utility model, screw shaft of ship nominal endocentric phrase of the each installation of difference on the horizontal shaft of the front stern tube gland of good stern tube shaft and the longitudinal axis in not descending water and having determined, these two screw shaft of ship nominal endocentric phrases are arranged at an angle of 90, the adapter plate of screw shaft of ship nominal endocentric phrase is arranged on to the gland correspondence position of front stern pipe, assembly opening on adapter plate is alignd with the mounting hole on gland, fastener is through the assembly opening on adapter plate and the mounting hole on gland, thereby adapter plate and gland are fastened as a whole, make the riser on adapter plate parallel with stern tube shaft, and the riser of the screw shaft of ship nominal endocentric phrase of the riser of measuring and record the screw shaft of ship nominal endocentric phrase in horizontal direction to the distance a at stern tube shaft edge and is longitudinally to the distance b at stern tube shaft edge, after launching, by checking apart from a and distance b, to determine whether stern tube shaft has skew, if there is skew, again for stern tube shaft axis fixed in, the riser distance of screw shaft of ship nominal endocentric phrase and the riser distance of longitudinal screw shaft of ship nominal endocentric phrase of stern tube shaft and horizontal direction are met apart from a and distance b, thereby reduce artificial by the man-hour through the middle stern tube shaft of assaying, increase work efficiency, the stern tube shaft that guarantee does not have front bearing precision in its axis fixed in water time, further ensure the hard-cover of vessel motion direction, this kind of screw shaft of ship nominal endocentric phrase, it is simple in structure, installation and easy to use.

Detailed description of the invention
Screw shaft of ship nominal endocentric phrase, as shown in Figures 1 to 4, comprise adapter plate 1, one end of riser 2 is vertically fixedly mounted on the surface of adapter plate 1, the two ends of riser 2 end faces that overlap with adapter plate 1 surface and the adapter plate 1 upper corresponding justify align in surface, be respectively arranged with assembly opening 3 on adapter plate 1 surface of riser 2 both sides.Screw shaft of ship nominal endocentric phrase of the each installation of difference on the horizontal shaft of the front stern tube gland 5 of good stern tube shaft 4 and the longitudinal axis in not descending water and having determined, these two screw shaft of ship nominal endocentric phrases are arranged at an angle of 90, the adapter plate of screw shaft of ship nominal endocentric phrase 1 is arranged on to gland 5 correspondence positions of front stern pipe, assembly opening 3 on adapter plate 1 is alignd with the mounting hole 7 on gland 5, fastener is through the assembly opening 3 on adapter plate 1 and the mounting hole 7 on gland 5, thereby adapter plate 1 and gland 5 are fastened as a whole, make the riser 2 on adapter plate 1 parallel with stern tube shaft 4, and the riser 2 of the screw shaft of ship nominal endocentric phrase of the riser 2 of measuring and record the screw shaft of ship nominal endocentric phrase in horizontal direction to the distance a at stern tube shaft 4 edges and is longitudinally to the distance b at stern tube shaft 4 edges, after launching, by checking apart from a and distance b, to determine whether stern tube shaft 4 has skew, if there is skew, be during stern tube shaft 4 axis are determined again, riser 2 distances of stern tube shaft 4 and the screw shaft of ship nominal endocentric phrase of horizontal direction and riser 2 distances of longitudinal screw shaft of ship nominal endocentric phrase are met apart from a and distance b, thereby reduce artificial by the man-hour through assaying middle stern tube shaft 4, increase work efficiency, the stern tube shaft 4 that guarantee does not have front bearing precision in its axis fixed in water time, further ensure the hard-cover of vessel motion direction, this kind of screw shaft of ship nominal endocentric phrase, it is simple in structure, installation and easy to use.
Riser 2 both sides are provided with while and the brace panel 6 that adapter plate 1 and riser 2 connect firmly, and by brace panel 6 is set, improve the stabilized conditions of riser 2, prevent that it is offset in long-term use.
One end of described riser 2 is vertically fixedly mounted on the middle part on adapter plate 1 surface, further guarantees that riser 2 facilitates side amount to the distance on stern tube shaft 4 surfaces.
Described brace panel 6 is modification of right-angled triangle plate, and its two square edges connect firmly respectively on adapter plate 1 and riser 2, by brace panel 6 is arranged to modification of right-angled triangle plate, has not only improved the stability of riser 2, also reduces inventory charge.
