Description
Technical field
The utility model relates to naval vessel steering wheel, is specifically related to the naval vessel steering wheel that a kind of hydraulic screw drives.
Background technology
As everyone knows, naval vessel steering wheel controls the requisite key equipment in traveling course, naval vessel, directly affects the advance on naval vessel, falls back, turns round, berths; Existing naval vessel steering wheel is various informative, as cross-head type, fork, roller type, pendulum cylinder-type, rotary blade type, spiral, taking up room of having is large, and some driving efficiencys are low, some bearing capacities are general, some manufacture requirements are high, and some life-spans are low, and some transmission accuracies are poor, some reliability are general, some installing/dismounting troubles, especially high-performance steering wheel needs to occupy a large amount of cabin space, and space is very important resource for naval vessel.
Summary of the invention
The purpose of this utility model is: provide the naval vessel steering wheel that a kind of hydraulic screw drives, volume is little, lightweight, and rudder moment is large, and operate steadily, good reliability, efficiency is high.
Technical solution of the present utility model is: this naval vessel steering wheel comprises cylinder cap, oil cylinder housing, piston, S. A., rudderpost and rudder blade, the inwall of oil cylinder housing welds spline housing, S. A. is established outer multi-thread helical spline, piston is established interior multi-thread helical spline and outer linear splines, S. A. is positioned at oil cylinder casing center, the flange face of S. A. is through plain thrust bearing, seal ring is arranged on bottom the inwall of oil cylinder housing, the flange face of S. A. installs rudderpost through screw or keyway, rudder the tip of the axis installs rudder blade, piston is by multi-thread helical spline in cooperatively interacting, outer multi-thread helical spline is arranged on the S. A. in oil cylinder housing, the outer linear splines matching spline cover of piston, piston forms two epitrochoidal chambers in oil cylinder housing, the wall of oil cylinder housing is positioned at epitrochoidal chamber place and establishes pouring orifice respectively, cylinder cap is threaded locking on the rotary shaft and be positioned at the inwall top of oil cylinder housing through seal ring, the overall naval vessel steering wheel forming hydraulic screw and drive.
Wherein, the outer wall bottom welding flange of oil cylinder housing.
The utility model has the following advantages: 1, all Transmissions are sealed in oil cylinder housing, and by the S. A. outputting torsion of centre, moment of torsion exports steadily; 2, all Transmissions are sealed in cylindrical oil cylinder housing, save installing space, due to two epitrochoidal chambers not gap leak even can be arranged under water, cabin area is better utilized; 3, the outer linear splines matching spline cover of piston can only moving linearly, S. A. can only do spinning movement by multi-thread helical spline in outer multi-thread helical spline fitting piston, the straight-line motion of piston and the spinning movement of S. A. are unified in oil cylinder housing, decrease parts, simplify processing technology, reduce installation and maintenance cost, extend service life.
Accompanying drawing explanation

In figure: 1 cylinder cap, 2 oil cylinder housings, 3 pistons, 4 S. A.s, 5 rudderposts, 6 rudder blades, 7 spline housings, 8 pouring orifices, 9 flanges.
Detailed description of the invention
As shown in Figure 1, this naval vessel steering wheel comprises cylinder cap 1, oil cylinder housing 2, piston 3, S. A. 4, rudderpost 5 and rudder blade 6, the inwall of oil cylinder housing 2 welds spline housing 7, S. A. 4 is established outer multi-thread helical spline, piston 3 is established interior multi-thread helical spline and outer linear splines, S. A. 4 is positioned at oil cylinder housing 2 center, the flange face of S. A. 4 is through plain thrust bearing, seal ring is arranged on bottom the inwall of oil cylinder housing 2, the flange face of S. A. 4 installs rudderpost 5 through screw or keyway, the end of rudderpost 5 installs rudder blade 6, piston 3 is by multi-thread helical spline in cooperatively interacting, outer multi-thread helical spline is arranged on the S. A. 4 in oil cylinder housing 2, the outer linear splines matching spline cover 7 of piston 3, piston 3 forms two epitrochoidal chambers in oil cylinder housing 2, the wall of oil cylinder housing 2 is positioned at epitrochoidal chamber place and establishes pouring orifice 8 respectively, cylinder cap 1 is threaded through seal ring and is locked on S. A. 4 and is positioned at the inwall top of oil cylinder housing 2 by plain thrust bearing, the overall naval vessel steering wheel forming hydraulic screw and drive.
Wherein, the outer wall bottom welding flange 9 of oil cylinder housing 2.
During installation, this naval vessel steering wheel is fixing above deck by flange 9; When coming about, operation hydraulic power unit, it is descending that high pressure oil enters promotion piston 3 in oil cylinder housing 2 through upper pouring orifice, thus S. A. 4 drives rudderpost 5 and rudder blade 6 to rotate, and completes handling maneuver; Otherwise high pressure oil enters in oil cylinder housing through lower pouring orifice and promotes piston stroking upward, completes reverse operating.
