Description
Technical field
The utility model relates to a kind of hydraulic sterring engine that boats and ships change course that is used for, particularly piston fork type hydraulic sterring engine.
Background technology
Hydraulic sterring engine is installed in the boats and ships afterbody cabin, it is the device that is used to control or change ship course, it is by loof mechanism, two motor pump power cabinets and a make-up tank are formed, loof mechanism comprises piston oil-cylinder (or plunger cylinder) and tiller, tiller two ends and piston rod (or plunger rod) flexibly connect, when hydraulic oil promotion piston (or plunger) moves to the left or to the right, the direction that the two ends of tiller are driven to predetermined rotates to an angle, the rudder blade that links to each other with tiller is rotation thereupon also, cause boats and ships to turn to the angle of rudder blade indication gradually, after boats and ships are adjusted to required course, rudder blade is transferred back to consistent with the boats and ships axis, boats and ships then continue line navigation with new direction.At present, the loof mechanism of hydraulic sterring engine both domestic and external mainly contains three types of plunger fork type, piston pendulum cylinder-type and rotary blade types.
The tiller two ends of plunger fork type loof mechanism are the shift fork structure, and two plungers are respectively equipped with bearing pin, and each plunger is equipped with a pair roller by bearing pin, the shift fork of tiller by two ends respectively with corresponding plunger on a pair roller fork-join.Advantage is that fork type loof mechanism power demand minimum is respectively about 68% of a pendulum cylinder-type, is 82% of rotary blade type under the situation of same output torque.Its shortcoming is, along with the increase of tiller corner, the moment of flexure that produces on plunger increases, because the restriction of strength of material, the operation pressure of oil cylinder can not be excessive, generally can only reach 11-15Mpa.Improving moment of torsion, can only be to increase plunger and cylinder diameter, causes the volume maximum, and cost is the highest.
Summary of the invention
The purpose of this utility model provides a kind of piston fork type hydraulic sterring engine, and it can overcome the shortcoming of existing fork type hydraulic sterring engine, under the situation of consumed power minimum, reaches bigger moment of torsion.
This piston fork type hydraulic sterring engine contains loof mechanism, two motor pump power cabinets and a make-up tank, loof mechanism comprises tiller and four hydraulic rams, it is characterized in that said hydraulic ram is a ram cylinder, piston rod radially is equipped with a bearing pin, one pair roller is loaded on the two ends of bearing pin, the tiller two ends by shift fork respectively with corresponding piston rod on a pair roller fork-join, the said piston rod outside is provided with the counter-force support.
The position that piston rod is installed roller is that cross-sectional plane is square bar section, and said bearing pin is installed on the square pole section.
The counter-force support is provided with a plurality of parallel little roller of transfer piston rod diametral load facing to the one side of roller.
In addition, Oil Tank and a filling tank in two motor pump power cabinets of this steering wheel are included in the same combination box, combination box is provided with the rudder stock mounting hole of vertical perforation, said tiller is supported in the aperture of this mounting hole of combination box by boss, and the lower end of tiller is stretched in this hole; Oil cylinder is fixed on the combination box by the counter-force support.
Be provided with axial force carrier bar pad between the areal of support of said tiller and combination box; Be provided with diametral load carrying cover between the hole wall of tiller and rudder stock mounting hole.
During the work of this hydraulic sterring engine, start oil pump, pressure oil promotes piston generation translation from an end of oil cylinder, the tiller certain angle that is driven to rotate simultaneously, tiller is in rotary course, the shift fork at its two ends is born by support by little roller transmission by piston rod the radial component that piston rod produces, and piston rod can not produce moment of flexure.This steering wheel is under the prerequisite that does not increase oil cylinder and the original diameter of piston, and operation pressure can be brought up to 20-24Mpa from original 11-15Mpa; This machine adopts double-acting piston cylinder to substitute the plunger case of existing shifting fork mechanism, side thrust of having only a side thrust to become piston cylinder by plunger case adds the opposite side pulling force, it is made a concerted effort is the 150%-170% of original plunger case, therefore volume is answered the corresponding 30%-40% that dwindles again, be that this steering wheel can smaller volume reach bigger moment of torsion, this means the reduction of this helm gear cost.In addition, this hydraulic sterring engine adopts integrated combination box, and casing is held concurrently and is support, the weight of carrying steering mechanism, and saved the rudder carrier bearing member that must independently be provided with in traditional steering wheel.This machine can be in the steering wheel originating firm be integrated into complete machine with each parts and finishes the debugging of steering wheel, and can go on board after complete machine dispatches from the factory is in place, and has saved a large amount of cost of installation.Compact conformation accounts for that on-deck is long-pending to be reduced greatly.
