Abstract
The utility model discloses a jigger device, which comprises a supporting shell of which the structure and size are matched with those of an engine motor, wherein a gear shaft is rotationally connected in the supporting shell; a gear which can be meshed with a gear ring of an engine flywheel is arranged on the gear shaft; and a notch which is exposed out of the gear and is conveniently meshed with the gear ring of the engine flywheel is formed on the supporting shell. The structure and size of the supporting shell are matched with those of the engine motor, so the device can be fixed by directly utilizing a start motor mounting hole of the engine, the gear is meshed with the gear ring of the flywheel, the gear shaft and a turning gear are rotated, the gear ring is driven, the engine is turned in a small transmission ratio driving mode, the time and labor are saved, and the jigger has high angle precision.
Description
Technical field
The utility model relates to a kind of barring gear.
Background technique
Motor needs motor is carried out jiggering when assembling, maintenance, adjustment, inspection, as: when being installed, should crankshaft disk to suitable angle be assembled piston rod part and gear chamber wheel module; When inspection, adjustment port timing, valve clearance, mechanical plunger oil pump feed advance angle, need jiggering, and higher to jiggering angle precision prescribed.Present branch motor is not suitable, effective, the labour-saving device is used for jiggering; Especially when keep in repair motor in electric dynamometer stand test and service station; Tester or on-site service personnel carry out jiggering with easy instrument such as bottle opener, crowbar to the motor peripheral accessory or to the coupling shaft that is connected with motor, and be poor to the control accuracy of jiggering angle, operator's technical ability required high; Damage motor and coupling easily; Time-consuming, effort, instrument is tried to shirk responsibility easily, causes personal injury.
Summary of the invention
The technical problem that the utility model will solve provides a kind of time saving and energy saving and barring gear that the jiggering angle precision is high.
For solving the problems of the technologies described above; The utility model comprises the support shell that adapts with engine cranking motor structure, size; Sprocket drive spindle is rotationally connected in the support shell; Be equipped with on the gear shaft can with engine flywheel gear ring meshed gears, have on the support shell and expose the breach that gear makes things convenient for the engagement of gear and engine flywheel gear ring.
After adopting said structure, the structure of support shell, size and engine cranking motor adapt, so can directly utilize motor self starting motor mounting hole to fix this device; Realize the engagement of gear and flywheel ring gear; Turning gear wheel shaft, dish moving gear, and then drive gear ring, adopt the close steps driving mode that motor is carried out jiggering; Time saving and energy saving, the jiggering angle precision is high.
Support shell is stretched out in the rear end of said gear shaft, through back-up ring is set at the gear shaft front end, that the gear shaft rear end is provided with baffle plate is spacing to support shell, baffle plate is through being bolted on the support shell.
Between said gear shaft and the support shell bearing is installed.
Said bearing is a deep groove ball bearing, not only can bear bigger thrust load, and its friction factor is very little, and using effect is good.
Said gear shaft rear end is provided with the square hole that is used for the plug-in mounting ratchet wrench, and instrument is difficult for landing during the dish moving gear, guarantees personal safety.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the sectional view of Fig. 2 along the A-A line.
Embodiment
Extremely shown in Figure 3 like Fig. 1; Barring gear comprises the support shell 1 that adapts with engine cranking motor structure, size; The sprocket drive spindle 2 that is rotationally connected in the support shell 1, be equipped with on the gear shaft 2 can with engine flywheel gear ring meshed gears 3, gear shaft 2 rear ends are provided with the square hole 7 that is used for the plug-in mounting ratchet wrench; Instrument is difficult for landing during the dish moving gear, guarantees personal safety.Have on the support shell 1 and expose the breach that gear 3 makes things convenient for gear 3 and engine flywheel gear ring to mesh.Support shell 1 is stretched out in the rear end of gear shaft 2, through back-up ring 9 is set at gear shaft 2 front ends, that gear shaft 2 rear ends are provided with 5 pairs of support shell 1 of baffle plate is spacing, said here rear end is meant that barring gear is installed in an end that is exposed behind the motor.The front end sealing of support shell 1; The rear end is provided with fastening flange 12; Fastening flange 12 is provided with the bolt hole 13 that matches with motor self starting motor mounting hole; On the gear shaft 2 in the support shell 1 from the front end to the rear end adjacent successively lining 11, back-up ring 9, gear 3, spacer 10 and the bearing 6 of being provided with, bearing 6 is installed on the shaft shoulder 8 of gear shaft 2, the baffle plate 5 adjacent shaft shoulders 8 are provided with and are fixed on through bolt 4 realizes spacing to support shell 1 on the support shell 1.Its middle (center) bearing 6 is a deep groove ball bearing, not only can bear bigger thrust load, and its friction factor is very little, and using effect is good.
The structure of support shell 1, size are corresponding with engine cranking motor; So can directly utilize motor self starting motor mounting hole to fix this device, realize gear 3 and flywheel ring gear engagement, turning gear wheel shaft 2, dish moving gear 3; And then driving gear ring; Adopt the close steps driving mode that motor is carried out jiggering, time saving and energy saving, the jiggering angle precision is high.Realize that the object of the invention is not only limited to above-mentioned this a kind of structure, also following structure can be arranged: directly at engine free end Design and Machining barring mechanism, as cast or install the jiggering nut in the boring of belt pulley cylindrical, in the crank pulley center of circle; Design special barring hole on flywheel casing is made and the similar jiggering frock of the specifically described device of this paper; Install coupling additional at the motor output terminal and can carry out jiggering, the focusing on of the utility model uses the close steps driving mode to carry out jiggering, realizes High Accuracy Control jiggering angle.
