Description
Technical field
The utility model relates to marine propulsion, is a kind of coming about with the crosshead machine of coming about specifically.
Background technology
Rudder for ship be a kind of be attached to hull outer, act on the dynaflow on the rudder blade when utilizing ship's navigation and control the device of ship course.In order to handle and control ship course, tradition adopts band transmission or gear transmission rudder stock to adjust the rudder blade direction, and its tape handler need be equipped with driven wheel, and existence takes up room big, and shock resistance is poor; Its gear drive, be 201120544525.3 disclosed novel full circle swinging oar loof mechanisms as the patent No., adopt worm-and-wheel gear transmission rudder rod, drive rudder rod by worm gear through worm screw and realize turning to of rudder blade, worm and gear is installed and used accuracy requirement height, cost height, and service life is short.
Summary of the invention
Taking up room of existing in the steering hardware at rudder for ship in the prior art is big, shock resistance is poor, install and use accuracy requirement height, cost height, the deficiency that service life is short, it is a kind of simple in structure, compact that the utility model provides, install and use convenient, cost is low, turn to stable, shock resistance, the crosshead of the long service life machine of coming about.
The technical solution adopted in the utility model is: a kind of crosshead machine of coming about, its technical characterstic is to comprise motor, lead screw shaft, mobile seat, revolving bed, tiller, rudder stock and rudder blade, motor connects the lead screw shaft that is supported on the bearing seat, mobile seat screw drive is connected on the lead screw shaft, revolving bed through the bearing swivel bearing on mobile seat, the single-revolution hole is set on the revolving bed, described tiller one end is connected to and is in the rotary hole along the rotary hole sliding mode, the tiller other end connects rudder stock, rudder blade is connected in to be on the rudder stock by tiller rotation and drives the rudder blade slew mode through rudder stock, and tiller around the rotation axis of rudder stock and the rotation axis of revolving bed on mobile in the same way.
Further, the rotation axis of described revolving bed on mobile seat is by the lead screw shaft kernel of section.
Further, described motor connects lead screw shaft through coupler.
Again further, described rudder stock is on the axial length Center Symmetry Plane of lead screw shaft.
During the machine of coming about work, motor drives lead screw shaft through coupler and rotates at bearing seat, mobile seat is connected on the lead screw shaft, be limited in through tiller, rotary hole and revolving bed by rudder stock and driven by the lead screw shaft screw thread rotation to move axially along lead screw shaft, revolving bed is limited in mobile seat by tiller through rudder stock, rotary hole and goes up rotation simultaneously, rotary hole rotates synchronously and drives tiller and move and drive tiller along the rotary hole direction and rotate around rudder stock, and the rudder stock rotation drives the rudder blade rotation and realizes coming about.
The utility model adopts lead screw shaft and tiller to limit mobile seat and revolving bed respectively, moved with revolving bed in mobile seat rotation along lead screw shaft by mobile seat, the common tiller that is connected on the revolving bed that drives, drive the rudder blade rotation by tiller through rudder stock and realize coming about function, this mechanism structure is simple, compact, install and use convenient, cost is low, turns to stable, shock resistance, long service life.
