Description
Technical field
The utility model belongs to connecting rod apparatus technical field, relates in particular to a kind of connecting rod for diesel engine transmission system.
Background technique
Connecting rod is for connection for transmission use, and the connecting rod of diesel engine transmission system is connected with bent axle.Connecting rod bears the periodicity gas pressure that transmitted by piston and the reciprocal inertia force of piston rod group.The current connecting rod for diesel engine transmission system is because design is unreasonable, thereby cause when in use due to stressed inhomogeneous, connecting rod is easier to come off with bent axle ratio, and wearing and tearing between connecting rod and bent axle are comparatively severe, serious impact service time of connecting rod of diesel engine transmission system.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of rational in infrastructure, and difficult drop-off between connecting rod and bent axle can be good at the connecting rod for diesel engine transmission system that extends its service time, and its technological scheme is as follows:
For the connecting rod of diesel engine transmission system, it is characterized in that the left bar head of the described connecting rod for diesel engine transmission system and right bar head are connected by bar axle between described left bar head and right bar head; Described left bar head comprises rectangular plate, and the upper-end surface of described rectangular plate is provided with plush copper, and the middle of described plush copper offers sunk structure, and described sunk structure comprises cone shape hole and cylindrical hole, and the tapering of described cone shape hole is 10 degree; On the upper-end surface of described rectangular plate, offer cylinder shape groove, cylinder shape groove communicates with cylindrical hole, and the diameter of cylinder shape groove is greater than the diameter of cylindrical hole; Described right bar head is cylinder, and the middle of described right bar head upper-end surface offers hemispherical groove; Arc transition between described bar axle and left bar head and right bar head.
The connecting rod for diesel engine transmission system that the utility model provides, when in use, described left bar head comprises rectangular plate, the upper-end surface of described rectangular plate is provided with plush copper, the middle of described plush copper offers sunk structure, described sunk structure comprises cone shape hole and cylindrical hole, and the tapering of described cone shape hole is 10 degree; .The sunk structure of plush copper makes whole left bar head more stable with being connected of bent axle, makes bent axle be connected to difficult drop-off on connecting rod.On the upper-end surface of described rectangular plate, offer cylinder shape groove, cylinder shape groove communicates with cylindrical hole, and the diameter of cylinder shape groove is greater than the diameter of cylindrical hole.The cooperation of cylinder shape groove and sunk structure can make connecting rod further stable with being connected of bent axle, and the motion of the bent axle that is also on connecting rod more flexible simultaneously, difficult wearing and tearing.Described right bar head is cylinder, and the middle of described right bar head upper-end surface offers hemispherical groove.Hemispherical groove can make connecting rod more flexible with coordinating of miscellaneous part, reduces kinetic friction, extends its service time.
The beneficial effects of the utility model are: rational in infrastructure, difficult drop-off between connecting rod and bent axle, can be good at extending its service time.
