Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
It is as shown in Figs. 1-2:
The utility model is a kind of fluid power variable transmission, and successively decrease the serial cylinder being connected and fixed including echelon diameter
The hydraulic cylinder of 100,200,300 compositions, hydraulic cylinder inside are filled with hydraulic oil, and hydraulic cylinder is plugged with the opposite drive being laterally arranged
Moving axis 400 and transmission shaft 700, drive shaft 400 and 700 opposite end of transmission shaft are respectively fixed with driving impeller 500 and driven impeller
600, drive shaft 400 and hydraulic cylinder activity grafting, the hydraulic oil angular momentum rate of decay of rotation are faster, slight to adjust driving impeller
500 can be realized different speed change ratios from the distance between driven impeller 600.
Preferably, 100,200,300 points of serial cylinder be the first cylinder 100, the second cylinder 200 and third cylinder 300,
The spoiler 110,210 of 200 inner vertical walls part fixed radial of first cylinder 100 and the second cylinder, spoiler 110,210 are disturbed
Stream effect, the hydraulic oil angular momentum rate of decay of rotation faster, improve the sensitivity of adjusting.
Preferably, 400 side wall of drive shaft of 500 left end of impeller is driven to be connected in hydraulic cylinder left end by elastic membrane 410
Wall reduces the rotational momentum of rotating hydraulic oil, reduces the rotating ratio of transmission by driving impeller 500 to hydraulic cylinder internal adjustment.
Preferably, 410 surface of elastic membrane offers hole, passes through convenient for hydraulic oil.
Preferably, drive shaft 400 is fixed with 700 abutting end of transmission shaft and abuts device 420, reduces rubbing in rotation process
It wipes.
Preferably, abut device 420 and be equipped with base 421 open at one end, inside 421 open end of base by ball 423 with
Grafting block 422 is in rolling contact.
Preferably, 424 internal diameter of groove that grafting block 422 opens up is identical as 700 diameter of transmission shaft and the two center of circle is coaxial,
It keeps stablizing during rotation, shockproof vibration causes equipment to be operating abnormally.
One concrete application of the present embodiment are as follows:
Change the depth that transmission shaft 700 is inserted into hydraulic cylinder, can be adjusted between driving impeller 500 and driven impeller 600
Distance, hydraulic oil viscosity with higher, driving impeller 500 rotate the hydraulic oil rotation in driving hydraulic cylinder, its own
Angular momentum successively decreases along hydraulic cylinder axial direction transmission process, due to realizing different transmission efficiencies, realizing different revolving speeds indirectly
Than, that is, realize variable speed, and since the flow-disturbing of spoiler 110,210 acts on, the hydraulic oil angular momentum decaying of rotation
Faster, different speed change ratios can be realized in slight the distance between the driving impeller 500 and driven impeller 600 of adjusting to speed.
The grafting block 422 in device 420 and 700 grafting of transmission shaft are abutted, abutting the rolling resistance 423 inside device 420 can prevent
Sliding friction generates heat, improves transmission efficiency, and traditional sliding friction will lead to forced contact face directly connecing due to material
