Abstract

The utility model relates to a manpowered accelerator which comprises a shell body and a main axle fixed on the shell body, wherein the main axle and a pedal connecting rod are fixedly connected. The main axle is also fixed with a driving big gear and a chain wheel bearing. A driven axle fixed on the shell body is fixed with a driving small gear and a driven big gear. The driving big gear is engaged with the driving small gear fixed on the driven axle. The driven big gear is engaged with the driven small gear arranged on the chain wheel bearing, and the driven small gear and a chain wheel are fixedly connected. The transmission of the utility model uses the combination of axle rotation and wheel rotation. The rotation of two different forms is realized on the same axle, and the big gear is used for driving the small gear for acceleration. Compared with the original moving result, the utility model has the advantages of time saving and labor saving.

Description

The manpower accelerator

Technical field

The utility model relates to a kind of accelerator, particularly a kind of manpower accelerator.

Background technique

Present speed regulator is the speed regulator of types such as electromagnetism, frequency conversion mostly, and mechanical industry is then comparatively common with speed reducer.The device the most similar to this patent function or structure can be example with the manpower multi-speed bicycle, its adjustment mainly relies on the variation of chain drum diameter and sprocket diameter and realizes, its major defect is: the first, speed adjustable range seldom, the velocity sense of people by bike before and after the speed governing is almost similar; The secondth, the arrangements for speed regulation more complicated breaks down easily and keeps in repair inconvenience; The 3rd is that the tower sprocket wheel difficulty of processing of this multi-speed bicycle is big, changes trouble, to the maintenance of bicycle with install and also have relatively high expectations.Its maximum shortcoming is that velocity variations is too little, almost is merely nominal.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of consumed power that do not need is provided, and does not also need the manpower accelerator of fuel oil.

For achieving the above object, the technical solution adopted in the utility model is: comprise housing and be fixed on main shaft on the housing, main shaft is fixedlyed connected with pedal rod, be characterized in, also be fixed with initiatively gearwheel and sprocket shaft bearing on main shaft, be fixed on and be fixed with driver pinion and driven gearwheel on the driven shaft on the housing, initiatively gearwheel is meshed with driver pinion, driven gearwheel is meshed with driven small gear on being installed in sprocket shaft bearing, and driven small gear is fixedlyed connected with sprocket wheel.

Another characteristics of the present utility model are: initiatively also be respectively arranged with on gearwheel and the sprocket wheel and prevent moving circlip and the circlip of string about main shaft and sprocket wheel; Also be respectively installed with main bearing and driven bearing on main shaft and the driven shaft, main shaft is fixedlyed connected by main bearing, sleeve rack and driven bearing respectively with driven shaft; The both sides of driven shaft also are respectively arranged with and prevent moving circlip and the circlip of string about driven shaft.

Transmission of the present utility model adopts axle to change and the combination of wheel phase inversion, has realized two kinds of multi-form rotations on same axle, and has quickened so that the large gear turn the small gear; Compare with former motion result, its advantage is to save time and leicht fallen D/A.

Description of drawings

Accompanying drawing is an overall structure schematic representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.

Referring to accompanying drawing, the utility model comprises housing 20 and is fixed on main shaft 4 on the housing 20, pedal rod 1 and main shaft 4 usefulness fixedly taper pin 3 closely link together, with circlip 2 and 18 limited main shaft 4 and sprocket wheel 15 about string moving, the continuity and the balanced rotation of mechanism have been guaranteed, flat key 5 is fixed on active gearwheel 6 on the main shaft 4, initiatively gearwheel 6 and driver pinion 7 can engagement driving,

circlip

8 and 14 two ends at driven shaft 11, with flat key 9 small gear 7 and driven shaft 11 are fixed together, in order to prevent the skew of main shaft 4 and driven shaft 11, driven bearing 10 links to each other driven shaft 11 with sleeve rack 19, the other end of sleeve rack 19 is connected with main bearing 21 on being sleeved on main shaft 4, and driven shaft 11 usefulness flat keys 13 are fixedlyed connected with driven gearwheel 12, driven gearwheel 12 and driven small gear 16 engageable transmissions, and driven small gear 16 is welded into a whole with sprocket wheel 15, can rotate around main shaft 4 by sprocket shaft bearing 17, sprocket wheel 15 arrives target to transmission of movement by chain.

Give main shaft 4 the manpower transmission of movement by pedal rod 1 during use, driving initiatively, gearwheel 6 rotates together, initiatively gearwheel 6 rotates driver pinion 7 speedups through meshed transmission gear, and by driven shaft 11 identical speed is passed to driven gearwheel 12 can make driven gearwheel 12 through these one-level transmissions speed and increase nearly 3 times than the speed of gearwheel 6 initiatively, after driven gearwheel 12 rotates with driven small gear 16 engagements, rotate around main shaft 4 with sprocket wheel 15, finish and be secondary speedup process, speed increases nearly 3 times once more, nearly 9 times have just been increased with the original velocity ratio of pedal like this, sprocket wheel 15 passes to operating movement spare to motion by chain, speed also can increase nearly about 3 times, and final velocity has improved more than 20 times as a result.

The utility model does not need consumed power, does not need fuel oil yet, makes a lower movement velocity movement parts obtain nearly tens times raising by the two-stage gear transmission under the effect of manpower, thereby make the motion speedup, single unit system is simple and compact for structure, and volume is little, in light weight, be convenient to install, adjust flexibly, the movement velocity transmission is steady, manufacturing expense is low, and is easy to maintenance, not consumes energy, economical and practical, and pollution-free.
