The utility model has the advantages that the working times in unit time are many, the utility model can effectively improve the power performance and the mechanical performance, prolongs the service life of the engine, and can cause the rotating speed of the engine to be decreased, the volume is reduced, the weight is light, and the cost is reduced.
Description
The utility model relates to technical field of engines.
The present explosive motor that uses, be four-stroke engine mostly, its piston needs upper and lower two weeks " work done " once, its shortcoming is, " work done " number of times in the unit time is few, and the motion wearing and tearing of piston and relevant other part of motion greatly, self big energy-consuming, engine speed and mechanical property are restricted, and the driving mechanism complexity, make the performance of explosive motor be difficult to further raising.
The purpose of this utility model provides a kind of one-stroke gear type engine, and it makes crankshaft-and-connecting-rod be reduced to the d-axis transmission, has simplified driving mechanism, has reduced the number of strokes of " work done " needs and the time that takies more, thereby has improved the power character of motor.
For achieving the above object, the utility model is taked following design proposal: the one-stroke gear type engine, form by cylinder body, piston, valve etc., the piston two ends are provided with intake valve, are socketed with spring on the fore-set of intake valve rear portion, are provided with the air inlet endless belt at the middle part of cylinder body, be provided with tooth bar in middle of piston, two end part at tooth bar are provided with suction port, are provided with exhaust valve at the two ends of cylinder body, and exhaust valve is equipped with cylinder head outward.
Described tooth bar is made of tooth bar in upper and lower, is provided with main d-axis at the cylinder body middle part, and the axle head of this main d-axis is equipped with tooth sector, when this tooth sector rotates, respectively with upper and lower interior tooth bar engagement.
Described tooth bar also can be made of upper and lower outer tooth bar, the side up and down of tooth bar is provided with the transmission tooth sector of engagement respectively outside, on the rotatingshaft of tooth sector, be coaxially connected with upper and lower tooth sector, be provided with the main d-axis gear that meshes respectively with it at the middle part of tooth sector about in the of two, the middle part socket master d-axis of this gear.
Motor respectively is equipped with cylinder head for the body upside-down that crouches at the left and right two ends of cylinder, be provided with the air inlet endless belt in the cylinder head center position, carries out air inlet and scavenging by the supercharging scavenging pump during work.Because cylinder is installed cylinder cap at two ends, has formed the condition of bilateral " work done ", because this condition causes and facilitate the double-action function of piston in one-stroke to produce, the left and right both sides of body one cylinder " work done " of promptly crouching.A piston is finished " advancing scavenging ", " compression " and " work done " in a single-stroke.This piston not only can front end " compression " in the work one way and rear end " work done " simultaneously, and belly-be can solve in the middle part of the piston to rotate and straight line motion, and can transfer out power.
Compared with the prior art the utility model has following advantage: unit time " work done " can reduce kinetic friction and from wasted work, can improve power character and mechanical property effectively often, prolong motor working life, engine speed is descended, volume reduces, in light weight, cost reduces.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model one-level d-axis drive mechanism schematic representation
Fig. 2 is the utility model secondary d-axis drive mechanism schematic representation
Fig. 3 is Fig. 2 piston structure schematic representation
Referring to Fig. 1: piston 8 two ends are provided with intake valve 9, on intake valve 9 rear portion fore-sets 6, be socketed with spring 7, be provided with air inlet endless belt 4 at the middle part of cylinder body 1, middle part at piston 8 is provided with tooth bar, be provided with suction port 12 at the two end part of tooth bar, be provided with exhaust valve 10 at the two ends of cylinder body 1, the exhaust valve 10 outer cylinder heads 11 that are equipped with; Described tooth bar is made of tooth bar 2,13 in upper and lower, is provided with main d-axis 5 at cylinder body 1 middle part, and the axle head of this main d-axis 5 is equipped with tooth sector 3, when this tooth sector 3 rotates, respectively with upper and lower interior tooth bar 2,13 engagements.
Working procedure is: when piston 8 was positioned at left stop and prepares " work done ", tooth sector 3 rear end level pressure intake valves 9 rear portion fore-sets 6 were opened exhaust valve 9, the cylinder space of its piston 8 right-hand members by admission endless belt 4 with 5kg/cm
2The high flow rate air inlet and the cleaning waste gas (at this moment exhaust valve 10 has been opened maximum position), tooth sector 3 on the main d-axis 5 begins with upper rack 2 engagements at this moment, when piston 8 left end works done, the thrust that is produced, make upper rack 2 drive tooth sector 3 and main d-axis 5 is clockwise rotated, form the one-level kind of drive, the gas of piston 8 right-hand members is compressed simultaneously, advance, exhaust valve 9,10 also close simultaneously, piston 8 continues right laterals, and gas pressure and temperature raise, and treats that piston 8 is before right stop during certain ignition angle, cylinder pressure and temperature all reach specified value, so produce outburst " work done ", drive tooth sector 3 and 5 rotations of main d-axis by tooth bar under the piston 13, at this moment the cylinder space of piston 8 left ends is done air inlet again, scavenging work, thereby main shaft 5 is constantly rotated and piston 8 continuous straight line motions, and the cylinder two ends constantly produce " work done "; So circulation can form the one-level transmission
Referring to Fig. 2, shown in Figure 3: described tooth bar is made of upper and lower outer tooth bar 16,23, the side up and down of tooth bar 16,23 is provided with the transmission tooth sector 15,22 of engagement respectively outside, on the rotatingshaft 14,24 of tooth sector 15,22, be coaxially connected with upper and lower tooth sector 18,21, be provided with the main d-axis gear 19 that meshes respectively with it at the middle part of tooth sector about in the of two 18,22, the middle part socket master d-axis 20 of this gear 19.
Working procedure is: the outer tooth bar 16,23 on the piston 17 drives the transmission tooth sector 15,22 in its outside respectively, and the tooth sector 18,21 on the rotatingshaft 14,24 drives main d-axis gear 19 rotations respectively, thereby driving main d-axis 20 rotates, outputting power forms the secondary d-axis transmission way of output.
Because diesel oil stroke and compression ratio are bigger, so be fit to adopt the secondary gear d-axis transmission way of output.
