Abstract

The invention discloses engine multifunction speed changing gear used in farm machinery. It is fixed chassis with splined shaft on flywheel. The chassis is respectively set two pulls with different diameter. And two driven gear wheels are respectively fixed on them. When one driving gear wheel moves to occlude with the driven, power with different rotate speed is produced; when another is racing, and moves to occlude with two driven gear wheels at the same time, the engine will not be start-up. This can realize self-locking theft-proof function.

Description

Engine multifunctional speed regulating device

Technical field

The present invention relates to a kind of arrangements for speed regulation, relate in particular to motor self-locking speed change multifunctional speed regulating device.

Background technique

The motor of exporting as power with belt pulley is widely used in farm machinery such as tractor, reaper, the size of its engine power is to set according to the load of agricultural mechanical operation, and most of farm machinery is in operation load when needing the transition walking load when being far smaller than operation that finishes, this moment, motor was in the state of low load with strong power, power factor is low, not only waste fuel, also bring unnecessary wearing and tearing.Also there are many users to install the bigger belt pulley of diameter additional in the outside of former belt pulley for this reason, take off the belt on the former belt pulley during underloading, load onto the belt of big belt pulley, the output power of motor is effectively utilized, save fuel oil for the rotating speed that reduces motor and play a good effect.But the effort that operates is time-consuming, and frequent loading and unloading also can damage belt.

Summary of the invention

The purpose of this invention is to provide on a kind of farm machinery motor and heavily cut and light cutting in operation, the single shortcoming of belt pulley output line speed during the transition walking for giving full play to the power of motor, reduces oil consumption and mechanical wear.

The present invention realizes with following technological scheme: a kind of engine multifunctional speed regulating device, it is characterized in that: it comprises the chassis that is fixed on the engine flywheel end face, the coaxial belt pulley I that is installed on the chassis, belt pulley II is installed in speed change gear group and gear controlling device in two belt pulley openings; The end face on described chassis is by the output terminal of some screw at engine flywheel; The inner splined hole of driving gear is installed on the splined shaft on chassis and can moves axially, and the driven gear I that is meshed with driving gear is fixed in the hole of end cap, end cap by some screw on the end face of belt pulley I; In the hole of belt pulley II, belt pulley II is installed on the cylndrical surface on chassis and can rotates moving gear II by double-row bearing, be fixed on the chassis with locking nut again by some screws and dowel fixes; The gear controlling device of being made up of pull bar, connecting rod is installed in the hole on chassis, inserts when the key of regulating tie bar position uses in the hole of base, takes out after using again.

On the bus of described base spline position symmetry on spline tooth root circumferential surface symmetry make two square grooves with the spline equal length, symmetry is made two counterbores that are complementary with the bearing pin cylindrical and corresponding with the hole on the connecting rod and equate on the inner spline gear tip circle side face of driving gear, and two springs and bearing pin are put into the hole respectively; The outside thread of connecting rod vertical end is screwed in the screw of pull bar; Make three annular recess on the outer peripheral surface of pull bar, position corresponding on the cylndrical surface on chassis makes the warp-wise through hole, to locate pellet shot from a slingshot, spring is packed in the through hole successively and is fixed with jackscrew, the pellet shot from a slingshot outer end places on the pull bar wherein groove, and the other end of pull bar is fixing minor axis and be complementary with the groove of key end radially.

Described gland compresses the outer shroud of bearing by some screw its end face boss on belt pulley I; Bearing gland is pressed on outer race on the chassis by some sunk screws.

In the groove of making on the adjacent surface on described belt pulley I and chassis dust ring is installed, suit dust ring in the gap of two belt pulley adjacent surfaces, setting-in dust ring III in the groove of making on the locking nut outer peripheral surface makes some counterbores on the outer Transverse plane.

Advantage of the present invention is:

1, speed change gear of the present invention is installed on the flywheel of motor, when machinery gently cuts, is effectively brought into play the output power of motor, save fuel oil, reduce engine scuffing, improve the life-span.

2, when driving gear meshes with two driven gears simultaneously, motor can't start, and reach self-locking action.Make machinery park Shi Buhui slide car, also help antitheft.

Fig. 5 is the left view of Fig. 4.

Among the figure: 1, chassis, 2, pull bar, 3, connecting rod, 4, spring, 5, bearing pin, 6, driving gear, 7, bearing gland, 8, driven gear I, 9, bearing, 10, dust ring I, 11, belt pulley I, 12, gland, 13, belt pulley II, 14, bearing, 15, dust ring II, 16, locking nut, 17, jackscrew, 18, spring, 19, the location pellet shot from a slingshot, 20, driven gear II, 21, pin, 22, screw, 23, key, 24, bar, 25, dust ring III, 26, groove, 27, minor axis, 28, flywheel.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, make the end face of the band seam that is complementary with the engine flywheel output terminal on the flange-like end cap on chassis 1, and be fixed on the flywheel end face with some screws, and it is coaxial with flywheel, size shape according to the engine flywheel end face of different model, can add transition disc when chassis and installation, make it with one heart and fixation.

Embodiment 1:

When motor gently cuts when working under the load condition, insert in 1 hole, chassis with key 23, rotating angled spoon 23 is inserted in the groove 26 of angled spoon 23 minor axis 27 of pull bar 2 ends, promote that key 23 promotes by the bearing pin in connecting rod 3 holes 5 that driving gears 6 move to left and be meshed with driven gear 8 on being fixed on gland 12, location pellet shot from a slingshot 19 drops on the pull bar in the groove of outer end, moving to prevent string, (among Fig. 1 represented position).Pilot engine, its power is delivered to belt pulley I rotation by chassis 1, driving gear 6, driven gear 8 glands 12, by belt with transmission of power to going out, belt pulley II 13 and driven gear II20 passed through bearing 14 and dallied on chassis 1 this moment.

Embodiment 2:

When starting machine side heavily to cut the following work of load, pulling out connecting rod 3 with key 23 makes driving gear 6 be meshed with driven gear 20, location pellet shot from a slingshot 19 falls into the groove of left end on the pull bar, the power of motor is transferred on the belt pulley II 13 by chassis 1, driving gear 6, driven gear 20 and makes it rotation at this moment, by belt transmission of power is gone out.At this moment, driven gear 8 and belt pulley I 11 1 idle running around the chassis.

When living car, engine misses, spur pull bar with key this moment, make location pellet shot from a slingshot 19 fall into the pull bar intermediate groove, 6 whiles of driving gear this moment are meshed with driven gear 8 and driven gear 20, because two diameter pulley differences, motor can't start, reach car self-locking effect, prevent that vehicle is stolen.
