Detailed description of the invention
Existing is carried out comparatively detailed description according to accompanying drawing to the utility model, as shown in Figure 1, a kind of helicopter driving device, comprise driving engine 1, gear case 6 and power-transfer clutch, the main shaft of described driving engine 1 is arranged with power-transfer clutch successively and gets rid of block 18, clutch cup cover 2 and the first synchronous pulley 3 bearing, described first synchronous pulley bearing is arranged with the first synchronous pulley 3, engine spindle 17 outside described first synchronous pulley 3 is screwed with check screw 19, described check screw 19 props up described first synchronous pulley bearing, driving engine 1 is provided with the second attaching parts 14, described gear case 6 is provided with the 3rd attaching parts 15, described 3rd attaching parts 15 is connected with the second attaching parts 14, pinion rotation axle on described gear case 6 is provided with from inside to outside successively the 3rd synchronous pulley 8 and the second synchronous pulley 7, described first synchronous pulley 3 is connected by the first Timing Belt 4 with described second synchronous pulley 7, the side that described gear case 6 is relative with described 3rd attaching parts 15 is provided with the first attaching parts 13, described first attaching parts 13 is provided with rotating shaft 11 in parallel, the two ends of described rotating shaft 11 are respectively equipped with the 4th synchronous pulley 9 and the 5th synchronous pulley 12, described 4th synchronous pulley 9 is connected by the second Timing Belt 10 with the 3rd synchronous pulley 8, described second synchronous pulley 7 and the 3rd synchronous pulley 8 are 1:1 transmissions, 4th synchronous pulley 9 and the 5th synchronous pulley 12 are 1:1 transmissions.
Described first Timing Belt 4 is provided with tension wheel 5.
Tension wheel 5 is affixed on the second attaching parts 14 by tension pulley support 16, and described tension pulley support 16 is provided with elongated hole, and described tension pulley support 16 is fixed on the second attaching parts 14 through described elongated hole by screw.
Principle of work: power-transfer clutch is got rid of block 18 and is located by connecting by the hole of the centre of itself and engine spindle 17, and their synchronous axial system is realized by a key, clutch cup cover 2 and the first synchronous pulley 3 are fixedly attached to one piece, and the first synchronous pulley 3 interstitial hole studs with bearing, namely the internal diameter of bearing is the diameter of engine spindle 17, engine spindle 17 connects through the bearing hole of the first synchronous pulley 3, and realize location by the boss that power-transfer clutch gets rid of on block 18, after being in place, the power-transfer clutch boss got rid of on block 18 just in time withstands the inner ring of the first synchronous pulley 3 bearing, last check screw 19 is tightened in the tapped bore on main shaft again, the bearing on synchronous pulley is pushed down with this, realize power-transfer clutch and get rid of fixedly securing of block and clutch cup cover and main shaft, when engine spindle 17 High Rotation Speed, power-transfer clutch gets rid of block and clutch cup cover 2 is just combined in one piece, because power-transfer clutch gets rid of block and spindle synchronous rotation, so when High Rotation Speed power-transfer clutch get rid of block and clutch cup cover 2 will synchronous axial system, because the first synchronous pulley 3 is fixed on clutch cup cover 2, so the rotation of clutch cup cover 2 drives again the synchronous axial system of the first synchronous pulley 3, when the first Timing Belt 4 rotates time, tension wheel 5 understands along with the rotation of the first Timing Belt 4 synchronous axial system, the tightness of the first Timing Belt 4 is regulated: by the position of the elongated hole on adjustment tension pulley support 16 and then the position of adjustment tension pulley support 16 by tension wheel 5, also the position of tension wheel 5 is namely adjusted, and then regulate the tightness of belt, synchronous pulley 03 and synchronous pulley 02 are fixed on an axle, this root axle is exactly the S. A. of gear case 6 inner gear, be fixed in gear case 6, gear drive in gear case 6 large oar main shaft drives large oar to rotate (not shown), rotation eventually through large oar can realize the upward movement of helicopter.And the second synchronous pulley 7 is all the same with modulus with the number of teeth of the 3rd synchronous pulley 8, they are 1:1 transmissions, 3rd synchronous pulley 8 is connected by the second Timing Belt 10 with the 4th synchronous pulley 9, is also 1:1 transmission between the 4th synchronous pulley 9 and the 5th synchronous pulley 12.When first synchronous pulley 3 rotates, the second synchronous pulley 7 is driven to rotate by the first Timing Belt 4, second synchronous pulley 7 drives the axle at the 3rd synchronous pulley 8 and their common place, gear in this root shaft driven gear case 6 rotates, and then drive large oar main shaft to rotate, large oar main shaft drives large oar to rotate, 3rd synchronous pulley 8 drives the 4th synchronous pulley 9 to rotate by the second Timing Belt 10, 4th synchronous pulley 9 drives the 5th synchronous pulley 12 to rotate, 5th synchronous pulley drives tail-rotor axle to rotate by Timing Belt, and then make tail-rotor rotate (not shown), then the motion of changing direction of helicopter can be realized.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
