Such as Fig. 1, shown in 2,3 and 4, central control mechanism external shell is divided into upper and lower two identical parts.Lower housing shell 1A
With, respectively with six bolts 2A, 2B, 2C, 2D, 2E are fixedly connected with 2F at 1a, 1b, 1c, 1d, 1e and the 1f of upper shell 1B；Bolt
Through upper shell 1B and it is screwed into lower housing shell 1A certain depths.Upper and lower half shell (1A and 1B) forms the sealing of central control mechanism
Shell, makes internal gear component away from dirt, humidity and accidental damage.
As shown in Figures 3 and 4, upper and lower half shell (1A and 1B) is all the folder being distributed by outer shroud 5a, inner ring 5b and intermediate symmetry
Region composition is held, six bevel gears 4A, 11,4B, 7B, 4C and 7A are clamped in this region.Leading screw 5A, 5B, 5C and power input
The axis of gear 11 is each passed through four holes 2a, 2c, 2d and the 2b of outer shroud 5a.Three leading screws are identical, and shaft end machined screw thread
(5A, 5B and 5C), the other end and enclosure interior gear (4A, 4B and 4C) are coaxially connected.
As shown in figs. 1 and 3, gear assembly include mesh together successively six bevel gears (4A, 11,4B, 7B, 4C and
7A).Due to the hexagonal array of gear, the axle clamp angle of two neighboring gear is 60 °, so selection Bevel Gear Transmission.Gear
Rotation axis intersects, and the number of teeth and modulus with identical quantity, without the ability for increasing or decreasing speed, is only used for changing biography
Dynamic direction.In order to which gear engages for the sake of simplicity, selecting straight bevel gear passing power between gear, if it is desired to pursuing more preferable
Tractive force and more stably run, it may be considered that using circular arc bevel gear, the intermeshing of this gear needs to use left and right
Revolve gear mesh.
As shown in figs. 1 and 3, in six bevel gears, gear 11 is driven by external input sources, and gear 4A, 4B and 4C are energy
Amount is transferred on elbow stent from central control mechanism, so gear 4A, 4B, 4C and 11 are known as driving gear.Operator passes through
13 input power of handle is to driving gear 11, and rotation with lifting jack, rotates clockwise very heavy to decline handle 13 counterclockwise
Top.External impetus input driving gear 11 is between two counter gears (4A and 4B).Another gear 4C is placed on gear
(4A and 4B) opposite side so that three gears (4A, 4B and 4C) form Y-shape configuration each other in 120 ° in central control mechanism.
Gear 7A is placed between gear 4A and gear 4C, and gear 7B is placed between gear 4B and gear 4C.The two gears (7A and
7B) only play the role of transmitting energy, be known as driven gear.
Each bevel gear (4A, 11,4B, 7B, 4C and 7A) both sides install thrust bearing (10A＆10B, 10C＆10D, 10E＆ additional
10F, 10G＆10H, 10I＆10J and 10K＆10L), in outer shroud U-type groove 3a-3f and inner ring U-type groove 4a-4f.Such as Fig. 3 and 4
It is shown, for this purpose, the stretched cylindrical shaft 6 in bevel gear (4A, 4B and 4C) side, bevel gear (7A and 7B) two side stretchings
Go out cylindrical shaft 8 and 9, the stretched cylindrical shaft 12 of input gear 11.Introducing thrust bearing makes sliding friction be changed into rolling friction.Work as tooth
When wheel group Tensile and compressive load, these thrust bearings also will endurance.In addition, lubrication is filled between all moving components
Agent ensures device even running to reduce friction.
As shown in Fig. 1,3 and 4, input gear 11 can also can be driven by 13 manual operation of handle with motor.Handle
Axis 19 is inserted into hole 15, and pin 16 is inserted into pin hole 17 and 18 and is fixed；Pass through this dismountable mode, thrust bearing 10D
It can also be connected with input gear 11.It is other when scene needs to control manually or electric power is unavailable, it is necessary to be operated manually
Under application conditions, controlled and faster be also more convenient using motor.
As it can be seen in figures 5 and 6, central control mechanism is separately mounted in the example of three arm type jack and hoistable platform.When
When input gear 11 is controlled either manually or by motor, three leading screws (5A, 5B, 5C) are pivoted at the same time.Leading screw substitutes rack
The function of being connected with pinion gear and elbow support assorted.Elbow stent is connected by six armed levers with upper lower roof plate.With leading screw
Level it is inside and outside slide, armed lever is around elbow stent folding, so as to be lifted/reduce hoisting apparatus, vice versa.
As illustrated in fig. 1 and 2, central control mechanism of the invention is easy to optimization design, also easy when required screw is longer
Installation.Gear both sides install thrust bearing additional, are easy to rotate, the frictional force of various aspects all minimizes.In addition, thrust bearing is also held
By all loads on power leading screw.
Although the embodiment of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, those of ordinary skill in the art are not departing from the principle of the present invention and objective
In the case of above-described embodiment can be changed within the scope of the invention, change, replace and modification.
