Description

A kind of spring starter

Technical field

The utility model relates to ignitor of IC engine, is specially a kind of spring starter.

Background technique

At present, the spring starter that is used for 12～30 horsepowers of single cylinder diesels in the prior art is by the central shaft assembly, overcoat, starting dog, clutch shifting blocks etc. partly constitute, the central shaft assembly is plugged in overcoat, be targeting part, drive part, the coaxial successively overall structure that is formed by connecting of output, targeting part links to each other with starting dog, drive part and overcoat are in transmission connection, output cooperates with the clutch shifting block, by manually rotating a starting dog around handle, leaf spring is wound in overcoat, carries out energy storage, the drive part of overcoat and central shaft assembly adopts ratchet (very heavy), ratchet mechanism, with bonding to transmission, the output of central shaft assembly front end is connected by key with the clutch shifting block, and when energy discharged, the central shaft assembly drove diesel engine starting by the clutch shifting block, its deficiency is: adopt ratchet between the drive part of central shaft assembly and the overcoat, ratchet mechanism, inertia is big during starting, and impact force is strong, and ratchet damages easily, ratchet breaks easily, and working life is short; The surface of contact of outer casing inner wall and targeting part is close to, and frictional force is big during starting, and the heat of generation easily with targeting part and overcoat sintering together; In addition, the output of central shaft assembly is connected by key with the clutch shifting block, causes when starting operation insensitive, the clutch inconvenience, and difficulty of processing is big.

The model utility content

The purpose of this utility model be to provide a kind of simple in structure, safe in utilization, the life-span long, easy to operate spring starter.

The technical solution of the utility model is:

A kind of spring starter, comprise the central shaft assembly, overcoat, starting dog, the clutch shifting block, the central shaft assembly is plugged in overcoat, be targeting part, drive part, the coaxial successively overall structure that is formed by connecting of output, targeting part links to each other with starting dog, drive part and overcoat are in transmission connection, output cooperates with the clutch shifting block, the outer wall at overcoat and the central shaft assembly place of being in transmission connection has the slideway that slides for roller, roller is housed in the slideway, and the slideway bottom opening is equipped with spring in the hole, spring holds out against drive part internal surface at the central shaft assembly with roller, forms roller, the spring one-way driving mechanism.

The utility model slideway can be 1～5.

The utility model slideway can be formed by connecting for plane and arc surface, and roller places arc surface.

The output of the utility model central shaft assembly and cross section, clutch shifting block joint can be for square, and the clutch shifting block has the square hole that cooperates with the output of central shaft assembly.

Between the utility model outer casing inner wall and the targeting part bearing can be installed.

The number of bearings of installing between the utility model outer casing inner wall and the targeting part can be at least two.

Compared with prior art, advantage of the present utility model and beneficial effect are:

1, adopt roller, spring one-way driving mechanism between the drive part of overcoat of the present utility model and central shaft assembly, can reduce bump during starting, performance is safe and reliable, long service life.

2, between outer casing inner wall of the present utility model and the targeting part closed type bearing can be installed, not need lubricating oil filling, wear-resistant, manually during energy storage, time saving and energy saving.

3, the output of central shaft assembly of the present utility model and cross section, clutch shifting block joint can be for square, and the clutch shifting block has the square hole that cooperates with output, thereby make the slide relative sensitivity of output and clutch shifting block, and be easy to process.
