Description
Technical field
The utility model belongs to the motorcycle engine technical field, specifically, relates to a kind of infinite variable speed engine speed characteristic experiment driven shaft gear.
Background technique
The purpose of motorcycle engine speed characteristic test: be whether to reach the design usage requirement by performance parameters such as the power of power measurer detection of engine under different operating modes (rotating speed) condition, moment of torsion, oil consumption.During test, need in power measurer, import the reduction speed ratio of speed changer.
The speed characteristic test of stepless variable engine because there is not speed changer in the stepless variable engine, is stepless change, can not accurately import reduction speed ratio, just the accurate performance parameter of each rotating speed point of test engine.
General little emission infinite variable speed engine all adopts the coupling of various types to connect with power measurer, adopts directly and carries out the engine speed characteristic test from crankshaft end.And the big stepless variable engine of discharge capacity, because power, moment of torsion are bigger, if directly from crankshaft end test engine performance, coupling and measurement of power equipment all damage easily with general coupling, this is the difficulty that each motor and motorcycle manufacturer all face.Be subjected to the restriction of power, moment of torsion and rotating speed, be difficult to find a suitable coupling.
In addition, higher to the concentricity requirement of motor and power measurer during installation from the crankshaft end test engine, the time that installation centering needs is longer; Because the speed characteristic test of stepless variable engine is different with the position of endurance test output, speed characteristic test is from the crankshaft end outputting power, and endurance test then is the output terminal outputting power from motor.During test, because output position difference, installs very inconveniently,, install just difficult more particularly for volume and all bigger large-duty engine of quality.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of infinite variable speed engine speed characteristic experiment driven shaft gear, in order to cooperate with driving shaft gear and buffer gear cold mechanism in the speed reducer, change stepless variable engine into the step change motor, be convenient to the performance parameter of accurate each rotating speed point of test engine.
The technical solution of the utility model is as follows: a kind of infinite variable speed engine speed characteristic experiment driven shaft gear, this driven shaft gear is made of integrated fluted disc and axle body, wherein fluted disc is positioned on the outer peripheral surface of axle body right-hand member, and both shaft axiss coincide; Described axle body is a through-pipe structure, and the hole wall place that takes back at axle body center hole middle part is provided with internal spline.
The utility model is bearing on the speed reducer by bearing, buffer gear cold mechanism engagement in fluted disc and the speed reducer, buffer gear cold mechanism and driving shaft gear engagement, speed reducer be fixed in the right lid of motor in conjunction with the plane, and the drive sprocket axle of motor (or bent axle) is connected with the gearbox primary shaft gear spline, the left end of axle body stretches out the left side of speed reducer in the utility model, make engine spindle pass its center hole, and connect by spline, the power of motor passes through driving shaft gear successively like this, buffer gear cold mechanism and driven shaft gear, pass to engine spindle at last, thereby realized changing stepless variable engine into the step change motor, just can be easily connect power measurer at the clutch end of motor this moment, accurate, carry out the speed characteristic test of large emission infinite variable speed engine quickly.
Offer circular groove in above-mentioned internal spline left side near on the inwall of axle body center hole port.Circular groove is used to install the O RunddichtringO, prevents that the lubricant oil in the driven shaft gear axle body center hole from spilling from splined end.
Extend to the left the left side of above-mentioned fluted disc, forms the annular stop boss.Positive stop lug boss is to the block bearing axial limiting of driven shaft gear, and it is simple, reliable to make driven shaft gear install.
The little step trough of imperial palace outside the right side of above-mentioned fluted disc offers, this step trough communicates with the axle body center hole, and both shaft axiss overlap, and the diameter of the little slot part of step trough is greater than the diameter of described axle body center hole.Step trough works to alleviate fluted disc weight; Simultaneously, axle sleeve is packed into by step trough in the axle body center hole, and spacing by step trough and the formed step surface of axle body center hole, axle sleeve when test is installed with the engine spindle Spielpassung, axle sleeve guarantees that with internal spline the transmission accuracy of driven shaft gear and power exports.
Beneficial effect: the utility model is installed on the speed reducer, it with speed reducer in driving shaft gear and buffer gear cold mechanism cooperate, be used for giving engine spindle with the transmission of power of motor, to realize changing stepless variable engine into the step change motor, convenient clutch end at motor connects power measurer, carries out the speed characteristic test of large emission infinite variable speed engine.The utility model plays transmitting torque, have simple in structure, characteristics such as installation is convenient, reliable transmission, employing has the working efficiency that speed reducer of the present utility model can improve Engine Block Test, carries out the speed characteristic test of large emission infinite variable speed engine accurately and quickly.
