Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further.
As illustrated, a kind of engine drive mechanism, including piston 1, dynamic transfering rod 2, connection section 3, floating-bush 4, company
Extension bar 5, positioning screw 6, revolution roller 7, guide rod, guide sleeve 9, impeller 10, one end of the piston 1 and dynamic transfering rod 2
Be fixedly connected, it is described connection section 3 be fixedly connected and be connected with dynamic transfering rod 2 be located proximate to dynamic transfering rod 2 away from piston 1
One end, the floating-bush 4 is flexibly connected with being connected section 3, and the connecting rod 5 has two, is connected to dynamic transfering rod 2
Opposite sides, the positioning screw 6 is connected to the one end of connecting rod 5 away from piston 1, and the revolution roller 7 is movably connected in tune
On the screw 6 of position, the guide rod has two, is connected to the opposite sides of dynamic transfering rod and can be stepped down to connecting rod 5,
The impeller includes axle sleeve 11 and at least four blades 12, and four blades are connected as a single entity, and the axle sleeve is located at impeller central and institute
The through hole that axle sleeve is provided centrally with coordinating with engine drive shaft 15 is stated, each outer rim of the blade 12 away from axle sleeve 11 is provided with
Step on step, several blades be connected as one and step close to the side of axle sleeve and axle sleeve close to the side of blade outer rim
Between have certain spacing, the spacing at least equal to revolution roller 7 diameter, two connecting rods 5 away from piston 1 one end difference
Positioned at the axial both sides of impeller 10, the revolution roller 7 is contacted with step, and the floating-bush 4 is with blade 12 away from axle sleeve 11
At regular intervals, the axle between the floating-bush 4 and blade 12 when the shape at edge is adapted, the piston 1 is in top dead centre
The axial both sides of set 11 are outstanding relative to blade 12.
In the utility model, the position coarse adjustment by adjusting connecting rod one end and impeller is turned round the place height of roller, led to
The place height for the position accurate adjustment revolution roller that adjustment positioning screw is arranged in connecting rod is crossed, to ensure piston after regulation in a word
Roller is turned round during in top dead centre to contact with positioned at step of the blade away from axle sleeve center.Passed by adjusting connecting rod with power
The spacing that spacing between bar can be between the revolution roller of coarse adjustment two is passed, passes through and adjusts what positioning screw fine setting revolution roller was installed
Spacing between position and two revolution rollers, so causes to protect by adjusting after abrasion when engine runs one end time
Card is stable.Impeller by 4 blades be connected as a single entity after constitute, the shape of blade has a variety of, such as each blade is away from axle sleeve
Side be between circular arc and blade and blade circular arc excessively, cause impeller overall away from being that convex arc is being at axle sleeve at close axle sleeve
Concave arc, flame tube floating tile are semicircle watt accordingly, and either what shape must all ensure that step is leaned on close to the side of axle sleeve with axle sleeve
Spacing between the side of nearly blade outer rim at least equal to revolution roller diameter, enable and turn round roller and pass through.This practicality
It is new to be oriented to track slot using preceding installed in each cylinder sleeve 14 of engine cylinder-body 13, each transmission mechanism is arranged on each cylinder
Piston is caused to be oriented to track slot with piston pin connection, guide rod insertion in set.
In use, revolution roller is with being located at step of the blade away from axle sleeve center when piston is in top dead centre（Each
Blade is that circular arc is excessive in this case between circular arc and blade and blade away from axle sleeve side, with the close apex of convex arc
Step is contacted）Contact.Because guide rod insertion is oriented to track slot when piston declines, dynamic transfering rod can be followed along linear motion
Piston linear declines, and dynamic transfering rod, which declines, causes floating-bush to drive blade rotation so that engine spindle with blade contact
15 rotations, connecting rod follows dynamic transfering rod decline to enable and turns round roller along platform while decline due to dynamic transfering rod
Terrace is moved, and revolution roller is with being located at step of the blade close to axle sleeve center when piston is in lower dead center（It is remote in each blade
Off-axis set side is that circular arc excessively in this case, connects with the step of the close apex of concave arc between circular arc and blade and blade
Touch）Contact, now piston drive blade rotation to cause engine spindle rotation, when piston rises back if up then revolution roller
The step that roller is located at the remote axle sleeve center of next impeller is turned round during top dead centre.It is different according to the quantity of blade, if
Be four this transmission devices of blade be used for two stroke engine piston rod up and down it is each once then do work twice, six blades actings
Three times, eight blades do work four times, if four this transmission devices of blade are used for four-stroke engine（Started with 6120 types
Exemplified by machine, transformation secondary piston diameter 120mm, piston stroke 140mm, crank throw radius 70mm improve rear engine main shaft and axle sleeve
On the axial width 120mm of mating part diameter 105.33mm, main shaft other parts diameter 95mm, axle sleeve thickness 60mm, axle sleeve, axle sleeve
Its a diameter of 105 mm through hole of through hole is interference fitted with main shaft, impeller is except setting the blade at step axially width 70mm, setting
Axial the widest part of blade at step is that 120mm protrudes 25mm per side platform rank relative to blade）Piston rod is respectively done twice up and down
Work(is secondary, six blades do work three times, eight blades do work four times, current science and technology temporarily at most accomplishes eight blades, more
Blade can not temporarily reduce the volume of engine and engine weight per horsepower can not be reduced, however not excluded that development in science and technology of future
More blades can be made.
Those skilled in the art may be used also it is to be understood that protection scheme of the present utility model is not limited only to the above embodiments
To carry out various permutation and combination and conversion on the basis of above-described embodiment, on the premise of without prejudice to the utility model spirit,
The various conversion that the utility model is carried out are all fallen within protection domain of the present utility model.
