Abstract
The invention discloses a barring gear for engine crankshafts, which is used for adjusting a dead center on an air valve so as to rotate a crankshaft. The concrete structure of the barring gear is as follows: the front end of a flywheel housing flange sleeve is inlaid with a small bearing, the outer end of a flange plate is inlaid with a large bearing, and the two axial sides of the flywheel housing flange sleeve are respectively provided with an opening window; the front end of a drive shaft is arranged in the inner ring of the small bearing, a driving gear is nested into the cross spline section of the drive shaft, and the outer end of the driving gear is arranged outside the opening window of the flywheel housing flange sleeve; and a positioning sleeve is arranged between the driving gear and the drive shaft, the butt end of the drive shaft is inlaid in the inner ring of the large bearing, and a driving handle is assembled at the mesh end of the drive shaft. By using the barring gear for engine crankshafts disclosed by the invention, a piston of an air valve can be stopped at any position so as to facilitate the adjustment on valve clearances; meanwhile, the indirect damage on other parts on a gear ring or an engine in the process of maintenance performed by using other tools can be avoided, and the maintenance time is saved; and because the driving gear can be removed, the barring gear can satisfy the requirements for valve clearance adjustment of engines in various types.
Description
Technical field
The invention belongs to the engine assembly repair kit, be specifically related to a kind of for adjusting the manual jiggering instrument that the valve top dead center position makes crankshaft rotating.
Background technology
In the engine assembling process, need turning crankshaft when adjusting the valve clearance, so that determine top dead center position.Because after the engine entrucking, be subjected to spatial constraints can only be on bell housing the position of through hole stir flywheel ring gear with screw tap and come turning crankshaft, this method very easily causes the destruction of gear ring except very dangerous, and also be not easy to control the anglec of rotation of bent axle, not only time-consuming but also require great effort.If a kind of engine crankshaft jiggering instrument can be provided, solve car load limited space system can not be freely clockwise and rotate counterclockwise bent axle, the institute of accurately locating the top dead center position problem and then be the industry asks.
Summary of the invention
The object of the present invention is to provide a kind of jiggering instrument that engine crankshaft is rotated with manual mode.
The object of the present invention is achieved like this (as Fig. 1 and Fig. 2): constituted fixture with flywheel shell joint dish and be used for being connected with the crankshaft-flywheel of engine by little bearing, big bearing; Driven wheel, positioning sleeve, driving shaft are used for jiggering as the machine driving sub-assembly.Concrete syndeton is: the front end of flywheel shell joint dish cover is inlayed little bearing, and big bearing is inlayed in the ring flange outer end of flywheel shell joint dish cover, and the axial both sides of flywheel shell joint dish cover are provided with open window.The driving shaft front end places little bearing inner race, and driving shaft is provided with crossing spline, and driven wheel is nested in the crossing spline section of driving shaft, and the outer end of driven wheel is positioned at the open window outside of flywheel shell joint dish cover.Positioning sleeve places between driven wheel and the driving shaft, and the thick shaft part of driving shaft is embedded in the inner ring of big bearing, and driving handle is assembled in the end of engagement of driving shaft.Large and small bearing fixing is equivalent to two strong points on flywheel shell joint dish.Starter on the engine is used to drive flywheel at ordinary times, and the present invention utilizes the fixing flywheel shell joint dish of starter interface on the flywheel shell of engine, promptly saves the space and also guarantees whole stability.Large and small two bearings not only play the effect that reduces to rub, and can also guarantee axiality preferably.Driving shaft is main power transmission shaft, front end is that crossing spline also cuts down finished cost in proof strength, the rear end be multiple tooth spline can multi-angle, rotate along contrary twocouese, driven wheel inside is that the cruciate flower keyway cooperates with driving shaft, the driving shaft front end cooperates with little bearing inner race, and locate with positioning sleeve the driving shaft rear end.
Characteristics of the present invention and beneficial effect are, use engine maintenance jiggering instrument, can make the valve piston be parked in the optional position makes things convenient for the valve clearance to regulate, avoid simultaneously when maintenance, using of the indirect damage of other instrument, also saved the working time of maintenance simultaneously other parts on gear ring or the engine.And because driven wheel is detachable, all are applicable to the adjustment requirement of polytype model engine valve clearance.

The specific embodiment
Below by specific embodiment structural principle of the present invention is described further.Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
Engine crankshaft jiggering instrument comprises flywheel shell joint dish 1, little bearing 2, driven wheel 3, big bearing 4, positioning sleeve 5, driving shaft 6 and driving handle 7 etc.Structural group becomes: the front end of flywheel shell joint dish cover 1 is inlayed little bearing 2, and big bearing 4 is inlayed in the ring flange outer end of flywheel shell joint dish cover 1, and flywheel shell joint dish overlaps 1 axial both sides and is provided with open window.Driving shaft 6 front ends place little bearing 2 inner rings, and the thin shaft part of driving shaft 6 is provided with crossing spline, and driven wheel 3 is nested in the crossing spline section of driving shaft, and the outer end of driven wheel 3 is positioned at the open window outside of flywheel shell joint dish cover.Positioning sleeve 5 places between the thick shaft part of driven wheel 3 and driving shaft 6, and the thick shaft part of driving shaft 6 is embedded in the inner ring of big bearing 4, and driving handle 7 is assembled in the end of engagement (as Fig. 1 and Fig. 2) of driving shaft 6.In order to be adapted to the crankshaft-flywheel of different model engine, and the requirement of different centre-to-centre spacing, driven wheel 3 is detachably changed.Ring flange and starter interface on the flywheel shell joint dish 1 install and fix.
Flywheel shell joint dish is an ironcasting.Driving shaft is divided into three sections, and first section is the thin axle that has crossing spline, an axle front end places and is used for the location in the little bearing, and the crossing spline section is used for assembling (stirring flywheel ring gear) driven wheel; Second section is thick shaft part, is used to assemble big bearing location; The 3rd section axle head headband has gear wheel, is used for and the driving handle engagement, as (manually) power source.The driven wheel center is provided with the cruciate flower keyway and cooperates with the respective drive axle, and the effect of positioning sleeve is to prevent driving shaft axial float (as Fig. 2).Needs are adjusted the valve clearance so that when determining piston top dead center position, starter flange 9 on ring flange on the flywheel shell joint dish and the engine crankshaft bell housing 8 is installed and fixed.The outer end of driven wheel protrudes in the open window outside of flywheel shell joint dish cover, its objective is with engine crankshaft on flywheel ring gear 10 mesh (as Fig. 3).By the rotating drive handle, manually jiggering can make flywheel 11 clockwise and rotate counterclockwise, and the valve clearance just can accurately be located.
During use, operator's right hand is held driving handle, and left hand reclines flywheel shell joint dish cover to flywheel, make the good engagement of flywheel on driven wheel and the bent axle, the assurance left hand position is motionless, and the right hand is the rotating drive handle up or down, drives flywheel ring gear by driving shaft and driven wheel and rotates.Not influencing under the assembly process situation, for more laborsaving, driving handle can be longer slightly.
