Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] see Figure 1-3 As shown, the present invention is a special flywheel for diesel engines that is easy to lift and assemble. The flywheel is composed of a front wheel 1 and a rear wheel 2. The front wheel 1 and the rear wheel 2 have the same structure. and the rear wheel disc 2 are provided with a number of fixing holes 3 on the outer periphery, and the fixing bolts 4 are inserted into the fixing holes 3 to fix the two wheel discs. The positioning hole 102 f...

The invention discloses a flywheel convenient to hoist and assemble and special for a diesel engine. The flywheel convenient to hoist and assemble and special for the diesel engine is composed of a front wheel disk and a back wheel disk. The front wheel disk and the back wheel disk are identical in structure. The periphery portion of the front wheel disk and the periphery portion of the back wheel disk are both provided with a plurality of fixing holes. Fixing bolts are inserted into the fixing holes, so that the two wheel disks are fixedly connected. The middle portion of the front wheel disk and the middle portion of the back wheel disk are each sequentially provided with a central shaft hole, locating holes and connecting holes from inside to outside. The front wheel disk and the back wheel disk are each provided with longitudinal hosting and assembling holes located besides the fixing holes, wherein the longitudinal hoisting and assembling holes and the fixing holes are alternately distributed. The middle portion of the front wheel disk and the middle portion of the back wheel disk are each symmetrically provided with a group of transverse hoisting and assembling seats and limiting grooves. The front end of each transverse hoisting and assembling seat is provided with a transverse hoisting and assembling hole, and the back end of each transverse hoisting and assembling seat is provided with a limiting portion. The flywheel convenient to hoist and assemble and special for the diesel engine is of a combined structure and provided with the multiple longitudinal hoisting and assembling holes and the two transverse hoisting and assembling holes, and the hosting and assembling demands can be met; and the transverse hoisting and assembling seats can be completely hidden in the limiting grooves after being assembled well, and normal operation of the flywheel cannot be influenced.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a special flywheel for diesel engines which is convenient for hoisting and assembly. Background technique [0002] The main function of the flywheel is to store the energy of the power stroke, overcome the resistance of the auxiliary stroke to maintain the uniformity of the crankshaft rotation, and make the internal combustion engine work smoothly. To this end, it must be able to store a certain amount of energy and release it when needed. When assembling a diesel engine for a vehicle, the flywheel needs to be hoisted, then installed in the flywheel housing of the diesel engine, and fixed on the crankshaft with multiple bolts. When lifting, it needs to be installed vertically (horizontal direction of the central hole axis). [0003] There are many flywheel spreaders at present, as the Chinese invention patent of application number 201610192632.1 discloses a kind of vehicle dies...
