Description
Technical field
The utility model belongs to heavy-duty car component technical field, relates to a kind of large diesel engine flywheel casing particularly.
Background technique
Flywheel casing is built-in with fly wheel assembly, bear the impact of the factors such as gravity, external force and irregular vibration due to it in using process, flywheel casing needs higher intensity, and simultaneously flywheel casing also plays the effect of connecting engine and gearbox, is one of important component of motor.Traditional flywheel casing is generally ironcasting, common are gray cast iron, spheroidal graphite cast iron etc., ironcasting has higher intensity, but its weight is also larger simultaneously, along with car load reduces day by day highlighting of oil consumption demand, increasing car load reduces the target of oil consumption by reducing deadweight to play, and flywheel casing, as motor holds great good, also needs to reduce its deadweight.
At present, have part producer to adopt aluminum alloy casting flywheel casing, as Chinese utility model patent CN201706143U, disclosed a kind of flywheel shell of engine, as shown in Figure 3, adopts aluminum alloy casting, housing is also furnished with the stiffening rib in net-like frame structure.Adopt aluminum alloy can reduce the weight of flywheel casing, but intensity also can reduce simultaneously, although be furnished with stiffening rib on housing, but can not requirement of strength be met for high-mechanic region, or in order to meet, requirement of strength needs layout is complicated, a fairly large number of stiffening rib, adds casting difficulty.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, provide a kind of lightweight, intensity is high and be easy to cast large diesel engine flywheel casing.
The technical solution of the utility model is: a kind of large diesel engine flywheel casing, comprises the flywheel casing body become by aluminum alloy cast appearance, and described flywheel casing body comprises shot peening portion, and described shot peening portion is positioned at the high-mechanic district of flywheel casing body.
Adopt aluminum alloy casting flywheel casing, the deadweight of flywheel casing is less, light quality, can effectively reduce complete machine weight, reduce complete-vehicle oil consumption further; Adopt shot peening in the high-mechanic zone position of flywheel casing body, the bulk strength of flywheel casing can be ensured, effectively ensure that reliability and the durability of complete machine, and then flywheel casing is met quality is light, intensity is high usage requirement.
Preferably, described high-mechanic district is positioned at left bottom and the region, lower right of crankshaft rear oil seal mounting hole.Carry out shot peening in this region, shot-peening coverage scale 200% can be realized, to gain in strength.
Preferably, the side described flywheel casing body is connected with cylinder block is provided with stiffening rib.The bulk strength of flywheel casing can be strengthened.
Further, described stiffening rib comprises the radial stiffening rib being positioned at flywheel casing body lower part and the latticed stiffening rib being positioned at flywheel casing body upper part.According to structural feature and the stressing conditions of diverse location, multi-form stiffening rib is set, makes flywheel casing stressed more reasonable, improve the ability of bearing vibration and load under bad road surface.
Preferably, described flywheel casing body is provided with rear power takeoff mounting hole, starter motor mounting hole and crankshaft position sensor mounting hole.Integrated several functions, can simplify the design of engine body.
Further, described rear power takeoff mounting hole, starter motor mounting hole and crankshaft rear oil seal mounting hole are triangularly arranged.Reasonable Arrangement makes the compact to design of flywheel casing, is easy to install and maintenance.
Further, two side positions of described flywheel casing body are provided with motor rear support mounting hole, and the periphery of motor rear support mounting hole is provided with rear support stiffening rib.Can be convenient to install and can requirement of strength be met.
Preferably, the tapped hole described flywheel casing body is connected with gearbox is embedded with steel-wire screw-socket.Being dismounted for multiple times can be ensured.
The beneficial effects of the utility model are: first, and flywheel casing is cast by aluminum alloy and formed, and light quality, can effectively reduce complete machine weight, and then can reduce complete-vehicle oil consumption; Secondly, carry out shot peening in high-mechanic region, and at rational position optimal design stiffening rib, the bulk strength of flywheel casing can be ensured, improve whole aircraft reliability and durability; Again, the integrated several functions of flywheel casing can be made by the Integrated design of flywheel casing, and then simplify the design of engine body.In addition, flywheel casing of the present utility model has advantage compact to design, to be easy to installation and convenient for maintaining.
Accompanying drawing explanation

In figure, 1, flywheel casing body, 2, motor rear support mounting hole, 3, starter motor mounting hole, 4, crankshaft rear oil seal mounting hole, 5, steel-wire screw-socket, 6, crankshaft position sensor mounting hole, 7, rear support stiffening rib, 8, stiffening rib, 9, rear power takeoff mounting hole.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of large diesel engine flywheel casing of the present utility model, comprise the flywheel casing body 1 cast by aluminum alloy, adopt aluminum alloy casting to form, there is light quality, the advantage of the deadweight of flywheel casing and then reduction complete machine weight and complete-vehicle oil consumption can be reduced.
In order to avoid adopting the intensity of the flywheel casing after aluminum alloy to reduce, carry out shot peening at the high-mechanic zone position place of flywheel casing body 1.Particularly, high-mechanic district is positioned at left bottom and the region, lower right of crankshaft rear oil seal mounting hole, carries out shot peening, realizes shot-peening coverage scale 200%, to gain in strength in this region.
As shown in Figure 2, the side that flywheel casing is connected with cylinder block is provided with stiffening rib 8, particularly, be positioned at the stiffening rib of flywheel casing body lower part radially, the stiffening rib being positioned at flywheel casing body upper part is latticed, the design arrangement scheme of stiffening rib makes flywheel casing stressed more reasonable, improves the ability of bearing vibration and load under bad road surface.
As shown in Figure 1, on flywheel casing body 1, Integrated design has the crankshaft rear oil seal mounting hole 4 for installing crankshaft rear oil seal, be used for the rear power takeoff mounting hole 9 of rear power takeoff is installed, be used for the starter motor mounting hole 3 of starter motor is installed, be used for the crankshaft position sensor mounting hole 6 of crankshaft position sensor is installed, wherein, crankshaft rear oil seal mounting hole 4, rear power takeoff mounting hole 9 and starter motor mounting hole 3 are triangularly arranged.
Be provided with motor rear support mounting hole 2 in the both sides of flywheel casing body 1, the both sides of motor rear support mounting hole 2 are provided with latticed rear support stiffening rib 7, while integrated several functions, guarantee the intensity of flywheel casing.
The tapped hole that flywheel casing body 1 is connected with gearbox built with steel-wire screw-socket 5, thus can ensure being dismounted for multiple times, is convenient to maintenance.
