Description
Technical field
The utility model relates to a kind of explosive motor, refers to a kind of driving mechanism of explosive motor especially.
Background technique
Traditional explosive motor is to adopt connecting rod to carry out transformation of energy, promptly the straight reciprocating motion of piston is transformed into rotatablely moving of bent axle, again rotatablely moving of bent axle is transformed into the linear reciprocating motion of piston.The reciprocal linear velocity of the rotational speed of bent axle and piston is quite high.Therefore, also quite strict to the technical requirements of connecting rod, though the technology of connecting rod is ripe day by day, still there is the defective that is difficult to overcome.
1, whenever piston is finished a circulation, at the initial instant of work done, the axis of the axis of piston, wrist pin and rod journal is on the same working plane, and this needs bigger starting force, only can finish the work done of piston by the rotatory inertia of bent axle.This is to cause one of motor in-fighting reason, and its accumulative total energy consumption waste degree is big, is the problem that those skilled in the art paid close attention to always.
2, piston makes crankshaft rotating by connecting rod, and the process of crankshaft rotating also is that connecting rod is the corner change procedure in axle center with the wrist pin.The corner of connecting rod is the main cause of wearing and tearing between piston and the cylinder.When connecting rod is in the hard-over angle, be best period of piston work doing efficiency, simultaneously, the frictional force between piston and the cylinder is also maximum.Therefore, connecting rod also is the main cause of piston and cylinder wear.
3, connecting rod is cooperating under the high-speed and high-temperature state with being slidingly matched of rod journal of bent axle.Between impact force that pivoting friction and rod journal bore be the main cause that connecting rod and rod journal damage.
The model utility content
The purpose of this utility model is to provide a kind of driving mechanism of explosive motor of alternative connecting rod, replace the bent axle transmission with meshed transmission gear, with the starting force that reduces piston, the wearing and tearing that friction was caused that reduce piston and cylinder, being slidingly matched with gear meshing replacement connecting rod and rod journal, effectively reduce the energy consumption of motor, improve power transmission efficiency.
For realizing described purpose, the utility model adopts following technological scheme: the utility model comprises piston, connecting rod, and an end of connecting rod connects with wrist pin.The end in addition of connecting rod connects a drive block, internal gear on the drive block and the external gear engagement that is connected on the transmission shaft.Internal gear on the drive block is non-round internal gear.Internal gear on the drive block is oval internal gear or round end flute profile internal gear.External gear on the transmission shaft is the cylinder external gear, and its calibration radius is less than the calibration radius of the minimum curve of the internal gear on the drive block.In order to guarantee internal gear and the engagement of the external gear on the transmission shaft on the drive block, drive block is provided with the engagement servomechanism that rotating shaft, gear and eccentric wheel constitute.Two eccentric wheels are fixedly connected respectively in two rotating shafts.By two gears being fixedly connected with two rotating shafts respectively and the driving gear engagement on the transmission shaft.In the drive block both sides consistent with the piston motion direction, two eccentric wheels and drive block rolling contact matching.Eccentric power is from transmission shaft, and by driving gear pass to and eccentric wheel with the gear that connects.External gear on the transmission shaft is under eccentric effect, with the internal gear engagement on the drive block.
The same with traditional explosive motor is that piston will pass through air inlet, compression, work done, exhaust stroke.Different is, piston promotes drive block by connecting rod and under eccentric effect, the internal gear on the drive block meshed with the external gear on the transmission shaft, and the velocity ratio between internal gear and the external gear has determined the rotating speed of transmission shaft.
Behind ato unit, the last external gear engagement of internal gear on the drive block and transmission shaft under the effect of engagement servomechanism, makes piston promote drive block by connecting rod and constitutes the thrust angle, and the starting force that reduces piston can be arranged; Adopt internal gear and external gear engagement on the drive block, obviously dwindle the angle of connecting rod and piston axis, effectively reduce the friction of piston and cylinder, further improve the piston operation situation; Replace being slidingly matched of connecting rod and rod journal with the contact between gear engagement, can not only reduce wearing and tearing, also alleviate piston effectively by impact force that connecting rod produced; Because the internal gear on the drive block and the engagement of the external gear on the transmission shaft are by the certain gear ratio operation, whenever finish a piston cycle, can realize the speedup of transmission shaft, can effectively improve power transmission efficiency.
As mentioned above, by improvement, can not only reduce the starting force of piston, the wearing and tearing that reduce piston and cylinder, alleviation piston to the impact of drive block and can effectively cut down the consumption of energy, improve power transmission efficiency to the explosive motor driving mechanism.
