Abstract
The present invention provides a kind of four rack rotary oil cylinders, to solve the problems, such as be：When the conditions such as the pitch circle of gear are identical, how to realize that output torque is twice of double rack rotary oil cylinder output torque, main points are：Two pairs of racks are engaged on gear, and it is in front two rows rack in tandem that these two pair rack is pressed in the axial direction of gear, and the facewidth of the gear is limited with that can place front two rows rack；The left and right end of each rack is fixed on homonymy piston cylinder.The positive effect of the present invention is：Identical in conditions such as the pitch circles of gear, output torque is twice of double rack rotary oil cylinder output torque；Gear corner under the same conditions, the length of rack does not increase, and when exporting same torque, the pitch circle of gear can become smaller, and processing cost and volume reduce.
Description
Technical field
The present invention relates to a kind of rotary oil cylinders（Or it is oscillating oil cylinder）.
Background technology
Rotary oil cylinder output torque.By rack quantity point, rotary oil cylinder mainly has monodentate rotary oil cylinder and double rack rotation
Turn oil cylinder, in the pitch circle of gear（Reference circle）, the conditions such as rack it is identical in the case of, the torque one of double rack rotary oil cylinder output
As be twice of monodentate rotary oil cylinder.Double rack rotary oil cylinder includes that a pair of of rack is engaged on gear, a pair of of rack engagement
In referring to that upper rack is engaged in the top of gear, lower rack is engaged in the lower part of gear, the end of upper and lower rack and pinion on gear
Face（Square with the axis plane）Place is in one plane.The left and right end of each rack is fixed on homonymy piston cylinder, counts four
Cylinder barrel.If desired when double rack rotary oil cylinder increase output torque such as reaches 100000NM or more, the pitch circle for increasing gear is needed,
At this moment the requirement to gear, rack is very high, and the difficulty of processing of gear increases suddenly；After the extended length of rack, bending resistance is corresponding
Weaken, also to solve bending resistance.If meeting it all to require, not only manufacturing cost is in non-linear growth, and volume also becomes
It is huge.
Invention content
In order to solve the above technical problems, the object of the present invention is to provide a kind of four rack rotary oil cylinders.
The object of the present invention is achieved like this：It is engaged in including a pair of of rack on gear, it is characterized in that：It further includes
For the engagement of another pair rack also on gear, it is in front two rows rack, standard in tandem that these two pair rack is pressed in the axial direction of gear
Gear is because of its facewidth（Length in the axial direction）It is limited, front two rows rack can not be placed, therefore the facewidth of gear needs to increase, institute
It states the facewidth of gear and is limited so that front two rows rack can be placed；The left and right end of each rack is fixed on homonymy piston cylinder, phase
Answer ground cylinder barrel and its piston to be also classified into front-seat cylinder barrel and heel row cylinder barrel, the cylinder barrel often arranged by orientation be divided into upper left, upper right, lower-left and
The cylinder barrel of bottom right four.There are two upper rack and two lower racks in above-mentioned two tooth-arranging strip, count four racks.
The course of work is, when the upper left cylinder barrel bottom right cylinder barrel this four to front-seat upper left cylinder barrel and bottom right cylinder barrel, heel row
When cylinder barrel notes pressure oil simultaneously, remaining four cylinder barrel pressure releases, front-seat upper rack, heel row upper rack move, are front-seat from left to right
Rack right-to-left moves under lower rack, heel row, and band moving gear rotates clockwise；When to front-seat upper right cylinder barrel and lower-left cylinder barrel,
When cylinder barrel and this four cylinder barrels of lower-left cylinder barrel note pressure oil simultaneously on back right, remaining four cylinder barrel pressure releases, two upper racks
Right-to-left is mobile, two lower racks move from left to right, and band moving gear rotates counterclockwise.
Compared with double rack rotary oil cylinder, the positive effect of the present invention is：It is identical in conditions such as pitch circle, the racks of gear
In the case of, output torque of the present invention is twice of double rack rotary oil cylinder output torque；Gear corner under the same conditions, tooth
The length of item does not increase, and when exporting same torque, the pitch circle of gear can become smaller, and processing cost can reduce, body
Product also greatly reduces.
Description of the drawings
It further illustrates the present invention below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of shape of the present invention.
Fig. 2 is the C-C sectional views of Fig. 1.
Fig. 3 is the A-A sectional views of Fig. 2.
Fig. 4 is the B-B sectional views of Fig. 2.
Specific implementation mode
It is engaged in including two pairs of racks on gear 4, and referring to Fig. 2, these two pair rack is pressed in tandem in the axial direction of gear
In front two rows rack, tooth-arranging strip before a pair of upper rack 3-1 shown in Fig. 4, lower rack 3-2 compositions, upper rack 5-1 shown in Fig. 3,
Tooth-arranging strip after lower rack 5-2 compositions, the facewidth of the gear are limited with that can place front two rows rack；Each rack is left and right
End is fixed on homonymy piston cylinder 2, corresponding ground cylinder barrel（And its piston）It is also classified into front-seat cylinder barrel and heel row cylinder barrel, the cylinder often arranged
Cylinder is divided into upper left, upper right, lower-left and the cylinder barrel of bottom right four, eight cylinder barrels of front two rows cylinder barrel meter by orientation.Above-mentioned two tooth-arranging strip
Count four racks.
Ginseng is seen figures 3 and 4, and the course of work is, when the upper left cylinder to front-seat upper left cylinder barrel 1-1 and bottom right cylinder barrel 1-3, heel row
Cylinder 2-1 this four cylinder barrels of bottom right cylinder 2-3 while when noting pressure oil, remaining four cylinder barrel pressure releases, front-seat upper rack 3-1, after
Row upper rack 5-1 is moved from left to right, and rack 5-2 right-to-lefts move under the lower rack 3-2 in front row, heel row, band moving gear up time
Needle rotates；When this four cylinders of cylinder barrel 2-2 and lower-left cylinder barrel 2-4 on front-seat upper right cylinder barrel 1-2 and lower-left cylinder barrel 1-4, back right
Cylinder is simultaneously when noting pressure oil, remaining four cylinder barrel pressure releases, front-seat upper rack 3-1 and heel row upper rack 5-1 right-to-lefts it is mobile,
The lower rack 3-2 in front row and front-seat lower rack 5-2 are moved from left to right, and band moving gear rotates counterclockwise.
