Description
Technical field
This utility model relates to actuating device, particularly relates to a kind of gear-driving speed-variable device.
Background technology
Existing gear wheel reversing gear, main employing is arranged side by side at least two axles, makes multipair gear engage each other and can realize gearshift and speed change by axial slip, but when there is the linear velocity difference of meshing gear, transmission stops even biting tooth phenomenon broken; Also have between power shaft and output shaft, be arranged side by side multiple jackshaft equipped with idler gear, so covert realizes gear shift by moving radially of gear, but needing extra version to promote forward or backward corresponding jackshaft, structure is more complicated and there is the problems such as inconvenient operation.
Summary of the invention
The purpose of this utility model is in that to avoid the deficiencies in the prior art to provide a kind of simple in construction, complete in gear-driven gear-driving speed-variable device.
For achieving the above object, this utility model adopts the technical scheme that: a kind of gear-driving speed-variable device, it is characterized in that: in change speed gear box (1), be provided with bevel gear shaft (3), driving shaft (5) and driven shaft (8), these three axles respectively through bearings on change speed gear box (1); Bevel gear shaft (3) is cased with two dish bearing a(4), separate with spacer (2) between them; Driving shaft (5) is cased with gear wheel a(6 from top to bottom successively), contiguous block (7), bevel gear (19), bearing g(21), gear wheel c(18), little gear d(22), bearing f(20), bearing h(23), rotating cylinder (25), cutterhead (26); Driven shaft (8) is cased with little gear a(9 from top to bottom successively), contiguous block (7), bearing b(11), jump ring (10), little gear b(12), bearing c(13), gear wheel b(16), bearing e(17), little gear c(14), two dish bearing d(15); Gear wheel d(24) it is bolted fixing with rotating cylinder (25); Bevel gear shaft (3) engages with bevel gear (19); Contiguous block (7) is provided with boss and gear wheel a(6) upper groove inlays the double; two flat key transmission mode of formation, gear wheel a(6) with little gear a(9) engage.
Described gear wheel c(18) and little gear d(22) formed duplicate gear I by bolt connection; Gear wheel b(16) and little gear c(14) formed duplicate gear II by bolt connection.
Described gear wheel a(6) with little gear a(9) for the gear train of the identical modulus difference number of teeth, change its speed by changing their position, thus changing the rotating speed of rotating cylinder (25) and cutterhead (26).
The beneficial effects of the utility model are: compact conformation is simple, stable drive, and transmission efficiency is high. Make full use of the effect of bearing, solve the technical problem that the gear that on same axle, multipair linear velocity is different is simultaneously engaged. This device can the feeding rotating cylinder of popularization and application and the silage harvester drum-type ceding of Taiwan and chopping disk speed governing.

Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
Embodiment 1, with seeing Fig. 1, a kind of gear-driving speed-variable device, it is characterised in that: in change speed gear box 1, be provided with bevel gear shaft 3, driving shaft 5 and driven shaft 8, these three axles respectively through bearings on change speed gear box 1; Bevel gear shaft 3 is cased with two dish bearing a4, separates with spacer 2 between them; Driving shaft 5 is cased with gear wheel a6, contiguous block 7, bevel gear 19, bearing g21, gear wheel c18, little gear d22, bearing f20, bearing h23, rotating cylinder 25, cutterhead 26 from top to bottom successively; Driven shaft 8 is cased with little gear a9, contiguous block 7, bearing b11, jump ring 10, little gear b12, bearing c13, gear wheel b16, bearing e17, little gear c14, two dish bearing d15 from top to bottom successively; Gear wheel d24 and rotating cylinder 25 are bolted fixing.
Bevel gear shaft 3 engages with bevel gear 19, driving shaft 5 is driven to rotate through flat key, contiguous block 7 rotates together with driving shaft 5 connection also through straight pin, contiguous block is provided with boss and gear wheel a6 upper groove is inlayed the double, two flat key transmission mode of formation and made gear wheel a6 rotate, gear wheel a6 engages with little gear a9, driven shaft 8 is driven to rotate again by contiguous block 7, driven shaft 8 drives little gear b12 to rotate by flat key, little gear b12 and gear wheel c18 engages the drive medium and small gear d22 of duplicate gear I and rotates, the size gear of duplicate gear I does not have drive connection by different bearing empty sets on driving shaft 5 with it, duplicate gear I medium and small gear d22 and gear wheel b16 in duplicate gear II engages and drives little gear c14 to rotate simultaneously, the size gear of duplicate gear II is absent from drive connection also by different bearing empty sets on driven shaft 8 with it. gear wheel d24 and rotating cylinder 25 are bolted and are integrated, and so little gear c14 and gear wheel d24 engages and just drives rotating cylinder 25 to rotate. and cutterhead 26 is by the powered rotation of the flat key transmission on driving shaft 5. gear wheel a6 and little gear a9 is the gear train of the identical modulus difference number of teeth, and the rotational speed regulation of rotating cylinder 25 can be realized by the position of change gear wheel a6 and little gear a9.
