Description
Technical field
The present invention relates to a kind of motor, relate to specifically a kind of rack-type motor.
Background technique
Existing motor, the deficiency such as what its power delivery structure mostly adopted is connecting rod, and this motor transmission efficiency combustion power low, motor with connecting rod can not fully be done work, mechanical wear large, structure is not compact.In order to allow motor more meet the demand of modern society, allow power performance, the economic indicator of motor produce qualitative leap, research is thought, the power transmission mechanism of motor only has the kind of drive that adopts tooth bar, free wheel device, gear shaft, just can make its " heat " and " power " be fully played and utilize.But, make engine operation reliable, except heighten tooth bar bearing strength, eliminate backlash, also exist and will guarantee that the piston movement of motor and the motion of distribution device have definite function relation, that is to say 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, may due to the frequent clutch campaign of free wheel device, cause the reliability variation of motor even to lose efficacy.
A kind of roller-type overrunning clutch of extensive use now, be suitable for high-speed drive, during work, there is no noise, 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 rotate by postive direction outer ring 14 ', the effect that roller 12 ' is subject to frictional force is by wedging in the groove 131 ' on star-wheel 13 ', thereby drive star-wheel 13 ' to rotate together, at this moment star-wheel, outer ring is in jointing state, when the 14 ' reversion of outer ring, 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 motor, just simply the outer ring of free wheel device is designed to toothed gear ring, and directly mesh with the tooth bar being connected with piston by pin, as shown in Figure 2, though realized like this unidirectional rotary motion that the straight reciprocating motion of engine piston is transformed into gear shaft (star-wheel of free wheel device is connected on axle), but to the power transmission mechanism as motor, free wheel device 15 ', 16 ' is arranged on such position, to there is very large hidden danger, one, clutch campaign due to 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 can't neglect, to cause engine piston to depart from the upper of the former setting of motor, corresponding position relationship mutually between lower dead center and timing sprocket, be about to make the engine compresses igniting can not timing, thereby make motor stable operation safely and reliably.Secondly, free wheel device is arranged on the position being meshed with piston-rack 17 ', 18 ', is about to free wheel device and is arranged near in the space of cylinder, is unfavorable for it to carry out cooling, lubricated fully.
Summary of the invention
The object of this invention is to provide a kind of high reliability rack-type motor, its stable drive, accurate, and be convenient to cooling, lubricated and maintain and replace.
In order to realize such scheme, technical solution of the present invention is: a kind of high reliability rack-type motor, 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, described first connecting rod tooth bar one side and the engagement of the first driving gear, opposite side and the engagement of the second driving gear, second connecting rod tooth bar one side and the engagement of the second driving gear, the starting gear engagement of opposite side and starting mechanism, described first, the 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, on engine support, also by bearing, is provided with output shaft, and output shaft is positioned at described first, between second driving shaft, output shaft and first, second driving shaft is parallel mutually, is fixed with output gear on output shaft, and described first, one end of the equidirectional of second driving shaft is fixed with respectively first, the 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 high reliability rack-type motor of the present invention is directly intermeshing with the first driving gear, stable drive, accurate, guarantees the constant position relation of piston and timing mechanism, thereby guarantees engine timing igniting.In addition, first, second free wheel device is individually fixed in the end of first, second transmission shaft, both guaranteed that engine power can effectively export, again not because the movement of free wheel device roller produces the constant position relation that accumulation Displacement error affect the upper and lower stop of piston and is connected in the timing sprocket on cam, and free wheel device shifts out outside cylinder, be convenient to cooling, lubricated and maintain and replace.
