Abstract
The utility model relates to a split crankshaft gear of a high-power diesel engine. The split crankshaft gear of the high-power diesel engine comprises a crankshaft and a spacer flange, wherein the spacer flange and the crankshaft are formed into a whole; the crankshaft is provided with a crankshaft gear; the crankshaft gear comprises a first split gear and a second split gear; the first split gear and the second split gear are assembled in the manner of butt joint to form the crankshaft gear; and the first split gear and the second split gear are connected with the end face of the spacer flange through connecting bolts. According to the split crankshaft gear of the high-power diesel engine, the first split gear and the second split gear are assembled in the manner of butt joint to form the crankshaft gear arranged on the crankshaft, and thus, the problem that the assembling is difficult because the diameter of the inner bore of the crankshaft gear of the high-power diesel engine is less than the outer diameter of a crankshaft flywheel flange is solved, so that the crankshaft gear and the crankshaft are simpler and more reasonable in disassembling and assembling. Moreover, the crankshaft gear and the spacer flange are connected to be locked by using the connecting bolts, and thereby, the work reliability of the crankshaft gear of the high-power diesel engine is greatly improved.

Technical field
The utility model relates to a kind of diesel engine, particularly a kind of high-power diesel engine split type crankshaft gear.
Background technique
At present, the spacer flanger of high-power diesel engine and bent axle basically all are the integral type designs on the market, and crankshaft gear is all-in-one-piece metal gear, is sleeved on the axial plane of bent axle, and adopt interference fit, are driven the rotation of crankshaft gear by bent axle.But this structure some problems can occur unavoidably in the process of installing and using.For example, the diameter of bore of integral one-piece crankshaft gear is less than the crankshaft-flywheel flange outer diameter, and crankshaft gear can't pass the crankshaft-flywheel flange and is enclosed within on the bent axle in the installation process, and can only be loaded into from the other end of crankshaft structure relative complex; Because crankshaft gear and bent axle interference fit, dismounting all needs special tool, the quite trouble that not only operates, and also its dismounting all can bring damage to bent axle and gear; The rotation of crankshaft gear is to rely on the friction of bent axle axial plane to come transferring power, and the damage of the damage of axial plane or crankshaft gear endoporus all can affect to the reliable delivery of power.
The model utility content
In order to overcome the problems referred to above, the utility model provides a kind of high-power diesel engine split type crankshaft gear.
The technological scheme that the utility model adopted is:
A kind of high-power diesel engine split type crankshaft gear; Comprise bent axle, with the spacer flanger of bent axle one; Crankshaft gear is installed on the bent axle, and said crankshaft gear comprises first and second subdivision gear, forms said crankshaft gear after first and second subdivision gear butt joint assembly unit; Said first and second subdivision gear is connected with the spacer flanger end face through connecting bolt.
As the further improvement of the utility model, the sign indicating number that said crankshaft gear is provided with first and second subdivision gear assembly unit locking closes bolt.
As the further improvement of the utility model, the said first subdivision gear is provided with breach, and the bolt head that sign indicating number closes bolt is positioned the breach upper surface, and screw rod penetrates first and second subdivision gear successively and both are locked.
As the further improvement of the utility model, said sign indicating number closes bolt respectively has 2 at the front and back of crankshaft gear.
As the further improvement of the utility model, said crankshaft gear is provided with the locating stud that is used to locate first and second subdivision gear.
As the further improvement of the utility model, said connecting bolt on first and second subdivision gear the symmetry respectively be equipped with 8.
The beneficial effect of the utility model is: formation was installed in the crankshaft gear on the bent axle after the utility model docked assembly unit with first and second subdivision gear; Solved the assembling difficult problem of the diameter of bore of high-power diesel engine crank axle gear less than the crankshaft-flywheel flange outer diameter, make crankshaft gear and bent axle dismounting more simply, more reasonable; In addition, crankshaft gear is connected locking with spacer flanger, has improved the functional reliability of high-power diesel engine crank axle gear greatly with connecting bolt.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial cutaway schematic of the utility model crankshaft gear.
Embodiment
As shown in Figure 1, a kind of high-power diesel engine split type crankshaft gear comprises bent axle 1, spacer flanger 2, and spacer flanger 2 is one-body molded with bent axle 1, and links with bent axle 1.The low order end of bent axle 1 is the crankshaft-flywheel flange that is used to install and fix crankshaft-flywheel.
As shown in Figure 2, crankshaft gear 3 is installed on the bent axle 1.Crankshaft gear 3 comprises first and second subdivision gear 31,32, and in the present embodiment, these two subdivision gears are actually material, modulus, half gear that the number of teeth is identical, have identical thickness and diameter of bore.Form complete crankshaft gear 3 after the two and half gears butt joint assembly unit, and the crankshaft gear after the assembly unit 3 is set in closely on the axial plane of bent axle 1 just.
First and second subdivision gear the 31, the 32nd closes bolt 5 assembly units lockings through sign indicating number.Wherein the first subdivision gear 31 is provided with breach 6; The bolt head that sign indicating number closes bolt 5 is positioned breach 6 upper surfaces; Screw portion penetrates in first and second subdivision gear 31,32 from top to bottom successively, and the tail end of screw rod is threaded with the second subdivision gear 32, realizes both lockings.Sign indicating number close bolt 5 and breach 6 the front and back symmetry of crankshaft gear 3 respectively have 2, totally 4, promptly close bolt two subdivision gear locks fastened with 4 sign indicating numbers, make the more secure that is connected of subdivision gear and bent axle.
The location that first and second subdivision gear 31,32 is corresponding has pin-and-hole, locating stud 7 to pack into and realize two subdivision gears in the pin-and-hole.
First and second subdivision gear 31,32 assembly units, fit on the bent axle 1 after, connect together with spacer flanger 2 end faces through connecting bolt 4 again, with bent axle 1 and spacer flanger 2 unitary rotation.For the dynamic balancing that guarantees that crankshaft gear 3 and bent axle 1 rotate, such connecting bolt on first and second subdivision gear 31,32 symmetry respectively adorn 8, and the axle center of each connecting bolt is all on the circular arc of a concentric, isodiametric circle.
