Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1, according to the bent axle oil pressure coupling of a kind of motor of the utility model embodiment, comprise coupling body 8 (see Fig. 4), it has the crankshaft installed hole 3 with the termination interference fit of bent axle 9, in the present embodiment, crankshaft installed hole 3 is cone shape hole (cone angle shown in Fig. 1 is X °).The hole wall in crankshaft installed hole 3 is provided with helical oil groove, helical oil groove has entrance point and clearing end, in the present embodiment, helical oil groove comprises main oil groove 4 and secondary oil groove 5, together with main oil groove 4 meets at the entrance point of secondary oil groove 5, the clearing end of main oil groove 4 and secondary oil groove 5 is separated from one another, and when coupling body 8 is assembled together with bent axle 9, the helical oil groove in crankshaft installed hole 3 and the outer wall of bent axle 9 surround closed ring shaped oil passage.In addition, the sidewall of coupling body 8 is provided with the jiont treatment hole 2 of high pressure oil, jiont treatment hole 2 is communicated with (see Fig. 2) with the entrance point of helical oil groove, in the present embodiment, jiont treatment hole 2 can be communicated with, in the present embodiment with the entrance point of main oil groove 4 with secondary oil groove 5 simultaneously, jiont treatment hole 2 is screw, connect high pressure oil joint when jiont treatment hole 2 is dismantled for oil pressure coupling, by jiont treatment hole 2, can reality simultaneously to main oil groove 4 and secondary oil groove 5 fuel feeding.
As a kind of preferred embodiment, the cross section of secondary oil groove 5 is V-arrangement (see Fig. 3).
As another kind of preferred embodiment, the inner end of coupling body 8 has flange (unmarked in figure), flange is provided with silicon oil shock absorber installation screw 1 (see Fig. 1), and silicon oil shock absorber installation screw 1 is for installing silicon oil shock absorber 7 (see Fig. 4).
