For solving the problem, the utility model provides a kind of abrasion-proof adjustable crankcase body, described abrasion-proof adjustable crankcase body comprises casing and cylinder block, described cylinder block tilts to be fixed on the side of described casing, described cylinder block is provided with fixed component, described fixed component is provided with mounting hole, the top of described casing is arranged with two fixed components, each fixed component is provided with strip hole away from one end of casing, crankshaft hole is provided with in described casing, camshaft hole, camshaft hole seat, crankshaft hole seat and collection chamber, described crankshaft hole seat and crankshaft hole are coaxially arranged, circular ring metal is inlaid with nested in described crankshaft hole, described camshaft hole seat and camshaft hole are coaxially arranged, described camshaft hole seat is provided with breach, described breach is communicated with described collection chamber, the position that described camshaft hole seat is positioned at described breach both sides is connected with stiffening rib, inwall and the camshaft hole seat of described stiffening rib and described casing are connected to form collection chamber.
Further, described metal is nested is ironcasting, and passes through die cast with casing.
Further, the thickness that described metal is nested is 9.8-10.2mm.
Further, described two V-shaped distributions of fixed component, and the strip hole of two fixed components is parallel to each other.
Further, have certain angle between described two fixed components, the size of described angle is 45-50 °.
It is nested that the utility model abrasion-proof adjustable crankcase body sets up metal in crankshaft hole, avoids crankshaft bearing and directly contact with casing, but by inserts and pivot friction, wear resistance is better; Fixed component is set up at the top of casing, and bar hole is provided with on each fixed component, in cylinder block, be provided with fixed component simultaneously, fixed component is provided with mounting hole, adjusts the position of casing, more accurate positioning during installation by bar hole, avoiding cannot adjustment assembly position, easily occur that fuel tank assembles situation not in place, improve efficiency of assembling, usability is guaranteed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model abrasion-proof adjustable crankcase body better embodiment.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model abrasion-proof adjustable crankcase body 1 better embodiment comprises casing 1 and cylinder block 2, and described cylinder block 2 tilts to be fixed on the side of described casing 1.Described cylinder block 2 is provided with fixed component 3, and described fixed component 3 is provided with mounting hole 31.The top of described casing 1 is arranged with two fixed components 4, and each fixed component 4 is provided with strip hole 41 away from one end of casing 1.
Crankshaft hole 11 13, camshaft hole 12, camshaft hole seat 14, crankshaft hole 11 13 and collection chamber 15 is provided with in described casing 1, described crankshaft hole 11 13 and crankshaft hole 11 13 are coaxially arranged, and are inlaid with circular ring metal nested 5 in described crankshaft hole 11 13.Described camshaft hole seat 14 is coaxially arranged with camshaft hole 12, and described camshaft hole seat 14 is provided with breach 141, and described breach 141 is communicated with described collection chamber 15.The position that described camshaft hole seat 14 is positioned at described breach 141 both sides is connected with stiffening rib 16, and inwall and the camshaft hole seat 14 of described stiffening rib 16 and described casing 1 are connected to form collection chamber 15.Camshaft is rotated the oil droplet that sputters and will to gather in collection chamber 15 and be lubricated to the camshaft of motion and camshaft bearing by breach 141 water conservancy diversion, therefore splash lubrication is made to have stronger directionality, make lubrication more abundant, reduce the wearing and tearing of camshaft and camshaft bearing, extend the working life of casing 1.
Described metal nested 5 is ironcasting, and with casing 1 by die cast, the thickness of described metal nested 5 is 10mm, is convenient to coordinate with casing 1 and crankshaft bearing.In other embodiments, the thickness of described metal nested 5 is 9.8mm, also can be 10.2mm.
Described two V-shaped distributions of fixed component 4, and the strip hole 41 of two fixed components 4 is parallel to each other.Have certain angle α between described two fixed components 4, the size of described angle α is 48 °, and certainly, in other embodiments, the angle between two fixed components 4 can also be 45 °, or 50 °.
The utility model adopts two fixed components 4 to be combined with a fixed component 3, be connected and fixed by three points by Triangle-Profile and casing 1, such casing 1 is installed reliably, good stability, even if by engine operation influence of vibration, casing 1 also can not occur to loosen and come off; The mounting hole 31 that fixed component 4 is installed for casing 1 is long strip, when assembling casing 1, conveniently can regulate casing 1 position, casing 1 be installed more convenient, effectively can improve the efficiency of assembling of casing 1.On crankshaft hole 11 13, be provided with metal nested 5 simultaneously, and metal nested 5 and casing 1 die cast, manufacturing is easy on the one hand, on the other hand; Casing 1 does not directly contact with bearing, but by inserts metal nested 5 and pivot friction, wear resistance is better, the bearing hole hole wall on casing 1 can be avoided to wear and tear, effectively extend the working life of casing 1.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; directly or indirectly be used in the technical field that other are relevant, all in like manner within scope of patent protection of the present utility model.
