Description
Technical field
The utility model relates to technical field of engines, is specifically related to a kind of linking mechanism for motor.
Background technique
Motor be a kind of can being converted into of other form another kind of can machine, normally be converted into mechanical energy to chemical energy.Motor both had been applicable to power generating apparatus, also can refer to comprise the whole machine of power plant.
Engine link is one of vitals of motor, and the effect of this engine link is that the power that piston bears is passed to bent axle, and makes the to-and-fro motion of piston change rotatablely moving of bent axle into.Connecting rod is comprised of parts such as connecting rod shank, connecting rod cap, connecting-rod bolts and connecting rod bearing shells.Connecting rod shank and connecting rod cap can be divided into connecting rod small end, thick stick body and connnecting rod big end.Connecting rod small end is connected with piston.Shaft is made " worker " or " H " shape section usually, in the hope of reduce quality under the prerequisite that satisfies the strength and stiffness requirement.Connnecting rod big end links to each other with the rod journal of bent axle.Generally make split, half of cutting with shaft is called connecting rod cap, and the two connects as one by connecting-rod bolts.Connecting rod bearing shell is installed in the crank pin end pore seat, is combined with rod journal on bent axle dress, and be one of most important matching pair in the motor.Antifriction alloy commonly used mainly contains white metal, copper lead alloy and acieral.
Conventional linkage is because wearing and tearing can be very fast aging, so need regularly connecting rod to be changed.How to design a kind of simple in structurely, easy to assembly and long-lived bar linkage structure is the problem that those skilled in the art need to solve.
Summary of the invention
Primary and foremost purpose of the present utility model just is to overcome the existing deficiency of existing bar linkage structure, thereby a kind of linking mechanism for motor is provided.
Linking mechanism for motor of the present utility model, the microcephaly of the connecting rod of this linking mechanism comprises and is connected and fixed structure and contacts fixed structure, describedly be connected and fixed the centre that structure is arranged at the microcephaly, described contact fixed structure is arranged at microcephaly's end, describedly be connected and fixed structure and piston is fastenedly connected, described microcephaly's end is fastened in the outside of piston.
The described structure that is connected and fixed is fastenedly connected by the wrist pin on bolt and the piston, and the wrist pin that described microcephaly's end is fastened on the piston is outside.
The described structure that is connected and fixed is to be provided with a cavity in microcephaly's centre, and described bolt is connected in series wrist pin and cavity, two of described bolt be individually fixed in the cavity and wrist pin on.
Described contact fixed structure cooperates with wrist pin is outside, contacts the outside of fixed structure contact piston pin and fixes wrist pin, makes contact fixed structure and wrist pin without relatively moving.
Described contact fixed structure is the arcuate structure of mirror image symmetry, and the radian of the circular arc that line becomes of this arcuate structure tail end section is identical with the radian of wrist pin.
The utility model is secured together wrist pin and connecting rod by bolt; the microcephaly of this connecting rod adopts arc to cooperate with wrist pin; make connecting rod and wrist pin without relatively moving; that is to say; when engine running; connecting rod all the time not can with other component generation relative movement, eliminated dexterously the wearing and tearing of connecting rod, so the high component of this importance degree of connecting rod have obtained good protection.After the normal wear such as wrist pin, bearing shell, during maintenance, only need replacing wrist pin, bearing shell to get final product, do not need connecting rod is changed, not only save time, more reduced maintenance expenses, Security is largely increased.
The utility model is simple in structure, be easy to process, thinking is novel, effectively eliminated the wear problem of connecting rod, at the piston structure that has satisfied particular design simultaneously, more make the assembling of connecting rod and piston become easy, and the piston rod group of reliability ratio conventional engines is higher, when satisfying performance requirement, save maintenance cost.Because there are friction in conventional connecting rod and wrist pin place, bring the harm such as wearing and tearing, vibrations and noise to component, will inevitably reduce the NVH performance of whole motor, and motor is lacked competitiveness.Adopt the connecting rod of this structure to solve well above problem.
Connecting rod of the present utility model is less than wearing and tearing, and in the whole life cycle of product, connecting rod does not need to change, only need to change connecting rod bearing shell, wrist pin and piston, the most direct impact is not only to save a large amount of time, reduction factory and user's maintenance expenses.From whole development situation, economical with materials and manufacture cost, more effective resource of having utilized.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.
As depicted in figs. 1 and 2, linking mechanism for motor of the present utility model, the microcephaly 1 of the connecting rod of this linking mechanism comprises and is connected and fixed structure 2 and contacts fixed structure 3, describedly be connected and fixed the centre that structure 2 is arranged at microcephaly 1, described contact fixed structure 3 is arranged at microcephaly 1 end, the described structure 2 that is connected and fixed is fastenedly connected with piston 4, and described microcephaly's 1 end is fastened in the outside of piston 4.
The described structure 2 that is connected and fixed is fastenedly connected by the wrist pin 41 on bolt 5 and the piston 4, and described microcephaly's 1 end is fastened in wrist pin 41 outsides on the piston 4.
The described structure 2 that is connected and fixed is to be provided with a cavity in microcephaly 1 centre, and described bolt 5 is connected in series wrist pin 41 and cavity, two of described bolt 5 be individually fixed in the cavity and wrist pin 41 on.
