Description

Mechanical starter

[affiliated technical field]:

The present invention relates to a kind of can equal energy source without electric energy, gas, the power when directly relying on engine operation converts the elastic force of spring (clockwork spring) to, then, discharges the novel mechanical equipment of this elastic force when resetting motor, is the direct utilization of mechanical energy.Especially, the mini engine to dependence manpower that starting mechanism is not installed brings help.

[background technique]:

At present, known majority all is that the storage battery cost is big by the motor of storage battery electric energy and manpower starting, and manpower is inconvenient again, and technology is not advanced.

[summary of the invention]:

In order to overcome at present existing starter motor (motor), storage battery damages easily, the cost height, mini engine needs the manpower starting again, shortcomings such as inconvenience, the invention provides a kind of starting machinery, many steel bar springs (clockwork spring) are set to be combined, power when utilizing motor work itself, flywheel rotates and drives steel bar spring (clockwork spring) rotation (in elasticity is spent mutually), allow clockwork spring be in maximum elastic force state, then, rely on this elastic force to reset motor, according to the size of engine power size decision clockwork spring model and clockwork spring quantity what.

The technological scheme that the present invention solves: one, in elasticity is spent mutually, make the elastic force of spring (clockwork spring) become maximum.Utilize engine power, flywheel rotates, driving steel bar spring (clockwork spring) rotates, increase the elastic force of steel bar spring (clockwork spring), as the power of resetting engine operation next time, this and engine flywheel gear ring meshed gears are called the elastic force gear, this axle is called the elastic force gear shaft, critical piece has: the elastic force gear, friction plate (dish), compressing tablet (platen), spring spindle, formations such as sprocket wheel, all on the elastic force gear shaft, when elastic force gear and flywheel ring gear engagement, active friction plate drives from movable friction plate, in order not damage steel bar spring (clockwork spring), do not exceed outside elasticity spends mutually, so, just can decide by the size of the mutual frictional force of debugging friction plate, that promptly regulates back compressing tablet spring flexiblely finds a suitable frictional force, after elastic force increases to a certain degree, just remain static from movable friction plate, active friction plate is still rotating, because be kept in motion relatively, the back just must be provided with a cover separating component, two compressing tablets all have a pair of protruding key in rotating mutually, there is spring to be open on the protruding key in back, utilizes conduit or connecting rod, sleeve pipe steel wire pulling spring spindle, with elastic force gear shaft jack-up, allow elastic force gear and flywheel ring gear disconnect, sprocket wheel drives another axle, another big sprocket wheel on the central shaft by chain, the bigger relatively sprocket wheel rotational velocity that slowed down has reduced the clockwork spring damaged condition.

On the central shaft there be critical piece: hinge wheel, braking plate (dish), brake assembly, gear, steel bar spring (clockwork spring), disk etc., braking plate is made of interior cover, overcoat, interior cover one-way rotation, the static braking state that is in of overcoat, central shaft drives steel bar spring (clockwork spring) one-way rotation, increase the elastic force of clockwork spring, braking plate is controlled by brake assembly, has only when motor need be reset, brake assembly opens, braking plate reverse rotation, central shaft cog and partly are connected in parallel and the rotation simultaneously of braking plate overcoat part with the braking plate overcoat.The following describes the core: it is how to increase the number of turns that starting gear rotates that many clockwork springs are combined.Because the diameter of flywheel is about 4 times of diameter of the gear of starter motor, therefore, starting gear must have enough rotation number of turns could allow engine operation.At first, the central point of central shaft and first clockwork spring is fixed, the not end of clockwork spring and disc circumference are a bit fixing, central shaft rotates and drives the rotation of clockwork spring central point, disk perimeter constitutes rock-steady structure with ball and shell, disk is that freely rotate in the axle center with the central shaft, equally, the centre point of disk quilt cover is fixed with the central point of next root clockwork spring again, a point of the other end of clockwork spring and next disk perimeter is fixed, and goes down successively, when central shaft rotates, drive all clockwork springs and rotate together, increase elastic force simultaneously.Since first clockwork spring, the width of clockwork spring steel bar reduces gradually, because the strength of first clockwork spring reduces gradually, last root is not held and is fixed on the shell.How much decide according to the multiple of the diameter of engine flywheel and starter gear and the such clockwork spring of how many roots to be set to combine.

Two, discharge elastic force, the work of piloting engine, another and elastic force gear shaft are symmetrical is called starter gear shaft, what be meshed with flywheel is called starting gear, is that rotate in the axle center with the central shaft, when motor need be reset, elastic force gear and flywheel open, the starting gear engagement, in addition, spring spindle is depressed.On the starter gear shaft there be critical piece: starting gear, starting shaft, driving gear formations such as (carrier gears), braking plate be meshed (circumscribed) that cog on starting shaft upper transfer gear and the central shaft, the starting shaft separated into two parts, the starting shaft of back heads on the front by spring, and the axle of front has the inclined-plane double wedge, when beginning to start, driving gear drives starting gear, when motor was started working, starting gear speeded up, and two-part of starting shaft separately.Another way, starting gear are divided into inside and outside two-part (principle that flies son with bicycle is the same), and interior cover part has unidirectional teeth, interior cover only can one-way rotation, and when beginning to start, interior cover drives overcoat and rotates, when the motor proper functioning, the overcoat rotating speed is greater than interior cover rotating speed, and overcoat freely rotates.The engagement of starting gear and flywheel on the starting shaft is to be controlled by the staff, is positively engaging, is the axle center with the central shaft, and after starting was finished, under the effect of spring torsion, starting gear disconnected, and the elastic force gear meshes with flywheel again.

Need press the decompression lever technological scheme to be solved that reduces pressure when below single cylinder diesel being started is described further:

Critical piece has centrifugal hammer, pull bar (push rod), return spring, sleeve pipe steel cable formations such as (conduits), two centrifugal hammers of subband on the driving gear, when static, centrifugal hammer is under the spring tension effect, withstand on circle centre position mutually, before the starting, vertical pull bar (push rod) is advanced between the centrifugal hammer, spring is arranged on the pull bar, but can not eject centrifugal hammer when static, simultaneously, drive decompression lever by sleeve pipe steel wire (or conduit) and press, along with the driving gear rotational velocity is accelerated, two centrifugal hammers open gradually, pull bar (push rod) ejects between the centrifugal hammer, and decompression lever is return under the spring torsion effect, begins the work of piloting engine.

When clockwork spring does not have elastic force, can use handle rocking-turn sprocket wheel.

The opening of the engagement of starting gear and flywheel, brake assembly, spring spindle depress etc. mutually between active force conduction, can use the pulling of conduit hydraulic pressure, sleeve pipe steel cable, the methods such as push-and-pull of connecting rod, when the staff operates, can use the manpower positively engaging, can be with means such as electromagnetic attractions.

The beneficial effect of the invention is: 1, do not need manpower to pilot engine, and 2, do not have the storage battery equal energy source, equally can the across-the-line starting motor.
