Description
Technical field
The present invention relates to a kind of motor, relate to a kind of rack type engine specifically.
Background technique
Existing motor, the deficiencys such as what its power delivery structure adopted mostly is connecting rod, and this driving engine efficiency combustion power that is low, motor with connecting rod can not fully be done work, mechanical wear large, structure is not compact.In order to the demand allowing motor more meet modern society, the power performance of motor, economic indicator is allowed to produce qualitative leap, research is thought, the power transmission mechanism of motor only has the kind of drive adopting tooth bar, free wheel device, gear shaft, and its " heat " and " power " just can be made to be fully played and utilize.But, make engine operation reliable, except heighten tooth bar bearing strength, eliminate except backlash, also exist and will guarantee that the piston movement of motor and the motion of distribution device have the function relation determined, that is in this tooth bar free wheel device, gear shaft type motor, also there is the problem of a free wheel device mounting point, if free wheel device mounting point is not right, then the less reliable of motor may be caused even to lose efficacy due to the frequent clutch campaign of free wheel device.
A kind of roller-type overrunning clutch of present extensive use, be suitable for high-speed drive, noise is not had during work, by star-wheel, outer ring, the composition such as spring spindle and roller, its structure as shown in Figure 1, the thrust of spring spindle 11 ' keeps roller 12 ' often to contact with outer ring 14 ' with star-wheel 13 ', when outer ring 14 ' is rotated by postive direction, roller 12 ' by the effect of frictional force by the groove 131 ' of wedging on star-wheel 13 ', thus star-wheel 13 ' is driven to rotate together, at this moment star-wheel, outer ring is in jointing state, when reversing in outer ring 14 ', roller 12 ' is pulled to part more spacious in groove 131 ', no longer wedging is in groove, at this moment outer ring and star-wheel are in separated state.If in rack type engine, just simply the outer ring of free wheel device is designed to toothed gear ring, and directly engage with the tooth bar be connected with piston by pin, as shown in Figure 2, though achieve the unidirectional rotary motion straight reciprocating motion of engine piston being transformed into gear shaft (star-wheel of free wheel device is connected on axle) like this, but to the power transmission mechanism as motor, free wheel device 15 ', 16 ' is arranged on such position, very large hidden danger will be there is, one, due to the clutch campaign of its roller, will make to produce certain displacement between the gear ring of clutch and spider gear shaft, although each displacement amount is very little, for thousands of motor per minute, its accumulation displacement then can't neglect, the upper of the former setting of motor is departed from by causing engine piston, position relationship mutually corresponding between lower dead center with timing sprocket, being about to make engine compresses to light a fire can not timing, thus make motor can not stable operation safely and reliably.Secondly, free wheel device is arranged on the position be meshed with piston-rack 17 ', 18 ', is arranged in the space of cylinder, is unfavorable for cooling fully it, lubricating by free wheel device.
Summary of the invention
The object of this invention is to provide a kind of rack engine, its stable drive, accurately, and be convenient to cooling, lubrication and maintain and replace.
In order to realize such scheme, technical solution of the present invention is: a kind of rack engine, comprises two connecting rod racks, first, second connecting rod tooth bar, described first, second connecting rod tooth bar is the two-sided rack, and described first, second connecting rod tooth bar is respectively by pin and motor first, the piston of the second cylinder is connected, and described first connecting rod tooth bar side is engaged with the first driving gear, opposite side engages with the second driving gear, and second connecting rod tooth bar side is engaged with the second driving gear, opposite side engages with the starting gear of starting mechanism, and described first, second driving gear is individually fixed in first, on second driving shaft, described first, second driving shaft is all arranged on engine support by bearing, and engine support is also provided with output shaft by bearing, and output shaft is positioned at described first, between second driving shaft, output shaft and first, second driving shaft is parallel mutually, and output shaft is fixed with output gear, and described first, one end of the equidirectional of second driving shaft is fixed with first respectively, second free wheel device, first, the outer ring of the second free wheel device is gear ring, the external toothing of the first free wheel device, the external toothing of the second free wheel device is all meshed with output gear.
Adopt after such scheme, because the connecting rod rack of rack engine of the present invention directly engages each other with the first driving gear, stable drive, accurately, guarantee the constant position relation of piston and timing mechanism, thus ensure that engine timing is lighted a fire.In addition, first, second free wheel device is individually fixed in the end of first, second transmission shaft, both ensure that engine power can effectively export, do not produce again accumulation Displacement error because of the movement of free wheel device roller and affect the upper and lower stop of piston and the constant position relation being connected in the timing sprocket on cam, and free wheel device shifts out outside cylinder, be convenient to cooling, lubrication and maintain and replace.
