Abstract

The utility model relates to a small universal petroleum engine starter, which comprises a ratchet mechanism 1, a starting wheel 7, a plane vortex ring spring 8, a starting cover 9, a dragline 10, a starting cup 11 and a crank 12. The ratchet mechanism 1 comprises a bolt 2, a press plate chute 3, a spring 4, a pawl 5 and a torsion spring 6; the starting cup is fixed on the crank 12, and the starting cover (not displayed in the figure) is fixed on the container of the petrol engine; the starting wheel is arranged on the starting cover by the plane vortex ring spring, and the ratchet mechanism is arranged in the starting cup. The utility model is characterized in that the starting cup is provided with a plurality of elongated holes 14; the starting wheel is provided with a ring dummy club, and the inner wall of the dummy club is provided with a plurality of grooves 13; the pawl of the starter is fabricated by the metal pawl. The cantilevered structure of the utility model is changed into simply supported mechanism; simultaneously, the plastic pawl of the starter is replaced by the metal pawl, thereby, the utility model reinforces the ability of the pawl of the starter to resist the impact torsion, and it enhances the reliability of the starter device.

Description

The small utility gasoline engine starting arrangement

One, technical field

The utility model relates to a kind of small utility gasoline engine starting arrangement.

Two, background technique

In the prior art, the reliability of the four-stroke universal gasoline engine starting arrangement that 8HP is following is very poor, main cause is to be fixed on the movable ratchet on the boot disk, the transmission of employing cantilevered fashion drive startup cup, when starting, because impulsive torque is bigger,, ratchet is fractureed, especially use and be to use the easier fracture of plastics ratchet, cause starting arrangement to lose efficacy.

Three, summary of the invention:

In order to overcome the prior art deficiency, purpose of the present utility model provides a kind of durable starting arrangement, improves the reliability of gasoline starting.

A kind of small utility gasoline engine starting arrangement (as shown in Figure 1) comprises ratchet unit 1, driving wheel 7, plane vortex ring spring 8, starting cover 9, stay cord 10, starting cup 11, bent axle 12; Described ratchet unit 1 comprises bolt 2, pressing plate chute 3, spring 4, ratchet 5, knob spring 6.As shown in Figure 1, the starting cup is fixed on the bent axle 12, and starting cover (not shown) is fixed on the casing of petrol engine, and driving wheel is installed on the starting cover by plane vortex ring spring, and ratchet unit places in the starting cup, simultaneously, is installed on the driving wheel.Be processed with some oblong aperture 14 on the starting cup, an annular boss is arranged on the driving wheel, be processed with some grooves 13 on the boss inwall.Two telescopic metal pallets 5 are arranged in the ratchet unit, when rotating with stay cord pulling driving wheel, ratchet unit promotes metal pallets and stretches out, and after passing the oblong aperture of starting on the cup, be pressed on the groove of driving wheel boss, thereby, make driving wheel and bent axle produce mechanical connection, bent axle rotates thereupon.Of the present utility model being characterised in that on the starting cup is processed with some oblong aperture 14; One annular boss is arranged on the driving wheel, be processed with some grooves 13 on the boss inwall; The ratchet of starter is that metal pallets is made.

The utility model makes the ratchet of starter into metal pallets, simultaneously, changes cantilever structure into freely-supported mechanism.Strengthen the ability of starter ratchet transmitting torque, thereby, the reliability of starter device improved.

Four, specific embodiment

Implementing has an annular boss as shown in the figure on the driving wheel, be processed with 4 grooves 13 on the boss inwall; Be processed with 4 oblong aperture 14 on the starting cup; Ratchet is selected Common Straight Carbon Steel for use.

Five, description of drawings

Fig. 1 is the axonometric drawing of starting arrangement;

Axial sectional view when Fig. 2 is the work of starting arrangement;

Fig. 3 is that the A-A of Fig. 2 is to view;

Fig. 4 cuts open figure for starting cup axle.

Among the figure: on 1-ratchet unit, 2-bolt, 3-pressing plate chute, 4-spring, 5-ratchet, 6-knob spring, 7-driving wheel, 8-plane vortex ring spring, 9-starting cover, 10-stay cord, 11-starting cup, the 12-bent axle, oblong aperture, the 13-groove of 14-starting cup.
