Description

The anti-assembling structure of engine starter

Technical field

The utility model is related to engine starting techniques fields, and in particular to a kind of installation knot of starter on the engine Structure.

Background technology

As shown in Figure 1, Figure 2, when existing starter is used for engine start, flywheel ring gear when to adapt to engine start The rotation direction of 2 fixed rotation directions, flywheel driving gear 4 is also changeless, at the same its installation site also can be only installed at it is winged Wheel shell 3 is on the flange of the side of engine cylinder body 1, this traditional starter mounting means, referred to herein as " formal dress side Formula ".

But often there is limited space needed for starter, cause starter body 5 that radial interference occurs with engine cylinder body 1 (in interference region such as Fig. 1 shown in part A), eventually leading to starter can not install or be installed again after cutting off interference portion scarce It falls into.

Utility model content

In view of the above technical problems, the utility model is intended under the premise of not changing available engine cylinder body, passes through change The installation site of starter avoids starter body that radial interference occurs with engine cylinder body.

For this purpose, technical solution used by the utility model is：A kind of anti-assembling structure of engine starter, including engine Cylinder body, flywheel ring gear, bell housing, flywheel driving gear and starter body, the flywheel ring gear is mounted in bell housing, and position Side far from engine cylinder body on the rear end of engine cylinder body, the bell housing is provided with anti-dress flange, the starter Body is mounted on anti-dress flange, and drives flywheel ring gear rotation by flywheel driving gear, described to fly to start engine Wheel drive gear is external toothing mode with flywheel ring gear.

As a preferred embodiment of the above solution, in terms of engine rear end, the anti-dress flange is located at the side position of keeping right of bell housing Place, flywheel driving gear are promoted from rear end forward end and are engaged with flywheel ring gear, and when starting engine, flywheel driving gear is clockwise Rotation, and flywheel ring gear is driven to rotate counterclockwise.

The utility model has the beneficial effects that：In such a way that formal dress changes counter fill, thoroughly solve starter body and hair Motivation cylinder body leads to the problem of radial interference, avoids the defect of formal dress mode limited space, simple in structure, ingenious in design.

Specific implementation mode

By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：

In conjunction with shown in Fig. 3, Fig. 4, a kind of anti-assembling structure of engine starter, wherein engine cylinder body 1, fly at flywheel ring gear 2 Wheel shell 3 is the component part of engine, and flywheel driving gear 4 and starter body 5 are the component parts of starter, dynamic by disk Starter, to start engine.

Flywheel ring gear 2 is mounted in bell housing 3, and positioned at the rear end of engine cylinder body 1, the rotation of flywheel gear 2 is by The flywheel driving gear 4 of motivation drives.Described above consistent with existing structure, details are not described herein.

Side far from engine cylinder body 1 on bell housing 3 is provided with anti-dress flange 6, and starter body 5 is mounted on anti-dress method On orchid 6, to realize the anti-dress of engine and starter.Starter drives 2 turns of flywheel ring gear by flywheel driving gear 4 Dynamic, to start engine, flywheel driving gear 4 is external toothing mode with flywheel ring gear 2.In short, traditional formal dress mode, Engine cylinder body 1 is respectively positioned on the front of bell housing 3 with starter body 5；And it is counter fill mode, engine cylinder body 1 is located at bell housing 3 Front, starter body 5 is located at the rear of bell housing 3, as shown in Figure 5.

Preferably, in terms of engine rear end, the anti-flange 6 that fills is located at the side position of keeping right of bell housing 3, certainly, also unlimited In right side, the circumferential any position far from 1 side of engine cylinder body on bell housing 3 can be set.Setting is accorded in right side, height Ergonomic is closed, and vacates enough operating spaces on the left of operator, is more convenient disk mechanical starter.Flywheel driving gear 4 from Rear end forward end propulsion is engaged with flywheel ring gear 2, and when starting engine, flywheel driving gear 4 rotates clockwise, and drives flywheel Gear ring 2 rotates counterclockwise.

It is usually fixed due to the rotation direction of engine flywheel ring gear, is also answered using the starter output rotation direction of anti-dress mode It is oppositely oriented with the starter output of formal dress mode, so also needing internal mechanism the rising in a manner of complying with and instead fill of transformation starter It is dynamic to require.

The anti-internal mechanism transformation for loading motivation：For all traditional formal dress starters, flywheel driving gear Rotation direction be only adapted to match flywheel ring gear under formal dress mode.Such as to adapt to not change after anti-dress mode the inside of traditional startup machine Structure, then (flywheel ring gear rotation direction is fixed not when all engine starts for the rotation direction of flywheel driving gear and the rotation direction of flywheel ring gear Become) on the contrary, cannot achieve the purpose that drive flywheel ring gear to rotate and then start engine.So anti-the starter of dress mode needs It to be transformed on the basis of traditional startup machine, the matched mesh of rotation direction of the rotation direction and flywheel ring gear that reach flywheel driving gear 's.

For existing disk spring energy-storage starter, when using formal dress, operation principle is as follows：Disk moving axis 11 is as schemed Show that 6 directions rotate, distal end disk moving gear 16 is driven to rotate, the helicla flute by geared sleeve 12 with movable snail sleeve 14 along main shaft 13 revolves Turn, while being compressed axially disc spring 17 and carrying out energy storage.Then ratchet 15 is discharged, disc spring 17 axially moves and driven by swivel nut 14 Main shaft 13 rotates, and main shaft 13 drives flywheel driving gear 4 to rotate and transfers torque on flywheel ring gear 2, it is made to rotate and rise Dynamic engine, engine cylinder body 1 are arranged with starter homonymy.

After anti-dress mode, 7 direction rotating disk moving axis 21 as shown simultaneously drives proximal disk moving gear 16 to rotate, by anti- Revolving geared sleeve 22 drives derotation swivel nut 24 to be rotated along the helicla flute of derotation main shaft 23, while being compressed axially disc spring 17 and being stored up Energy.Then release derotation ratchet 25, disc spring 17 axially move and drive derotation main shaft 23 to rotate by derotation swivel nut 24, derotation Main shaft 23 drives flywheel driving gear 4 to rotate and transfers torque on flywheel ring gear 2, it is made to rotate and start engine, sends out Motivation cylinder body 1 is separately positioned on the both sides of bell housing 3 with starter.

Disk spring energy-storage starter is mechanical starter, and in addition to this, the starter for engine further includes gas Dynamic formula, fluid pressure type or electrodynamic type, it is no longer exhaustive one by one herein.
