Abstract
An internal combustion engine crank shaft assembly comprises a first crank shaft block, a second crank shaft block, and a shaft pin used for connecting the first crank shaft block and the second crank shaft, wherein the shaft pin is sleeved with a bearing, and the bearing is sleeved with a connecting rod; a first connecting shaft is arranged at one end of the first crank shaft block, a first connecting head is arranged at the tail end of the first connecting shaft, and external threads are formed on the first connecting head; a second connecting shaft is arranged at one end on the second crank shaft block, a second connecting head is arranged at the tail end of the second connecting shaft, external threads are formed on the second connecting head, and external diameter from the second connecting shaft to the second connecting head reduces in a stepped manner, a clamping groove is further formed in the second connecting shaft, and a supporting rod is further arranged at the tail end of the second connecting head; a first correcting hole and a second correcting hole are oppositely formed in the positions of the axes of the first crank shaft block and the second crank shaft; each of the first correcting hole and the second correcting hole has a hole part with a section of smooth columnar inner surface.
Description
Technical field
The utility model relates to a kind of I. C. engine crankshaft parts.
Background technique
The appearance of internal-combustion engine, make mankind's industrial civilization progressive greatly, and general internal-combustion engine all comprises a bent axle, and bent axle connects connecting rod, and connecting rod connects piston, and piston is promoted crankshaft rotating by the detonation gas-powered, thereby realizes the output of bent axle arbor.Prior art particularly organize rotatable crank assemblby, higher to the concentricity requirement of two of left and right the first bent axle piece and the second bent axle, and existing crank assemblby concentricity calibrating is more inconvenient.
Summary of the invention
In order to overcome existing internal combustion engine crank shaft assembly coaxality verification identity distance from greatly, more do not put deficiency just, the utility model provides a kind of I. C. engine crankshaft coaxality verification internal combustion engine crank shaft assembly easily.
The technical scheme in the invention for solving the technical problem is: a kind of internal combustion engine crank shaft assembly, comprise first a bent axle piece, the second bent axle piece, the pivot pin that connects the first bent axle piece and the second bent axle piece, be arranged with a bearing on described pivot pin, described bearing outside is provided with connecting rod; On described the first bent axle piece, an end is provided with the first connecting shaft, and described the first connecting shaft end is provided with the first connecting head, and described the first connecting head is provided with outside thread; On described the second bent axle piece, an end is provided with the second connecting shaft, described the second connecting shaft end is provided with the second connecting head, described the second connecting head is provided with outside thread, and described the second connecting shaft dwindles to the second connecting head external diameter cascade, also be provided with a draw-in groove on described the second connecting shaft, described the second connecting head end also is provided with a strut; Hole is corrected in described the first bent axle piece be provided with first rectification hole and second relative to the second bent axle piece central axis position; Described first corrects hole and second corrects the hole section of one section smooth column of internal surface of hole existence.
The utility model is consistent with the internal combustion engine crank shaft assembly of existing technology in use, just when the verification coaxality, thereby can realize the rectification of combustion motor Y-axis by testing the first error of correcting hole and the second rectification hole inwall circle central axis, effect is apparent in view.
The beneficial effects of the utility model are: thus can realize by testing the first error of correcting hole and the second rectification hole inwall circle central axis the rectification of combustion motor Y-axis, verification is got up extremely low to the equipment requirement,, as long as a T-shaped probe that can stretch gets final product the verification coaxality, adjust easily simultaneously.
Description of drawings
Fig. 1 is an embodiment's of the utility model schematic diagram.
Fig. 2 is an embodiment's of the utility model horizontal schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
By reference to the accompanying drawings 1 to 2, a kind of internal combustion engine crank shaft assembly, comprise first a bent axle piece 1, the second bent axle piece 2, connects the pivot pin 3 of the first bent axle piece 1 and the second bent axle piece 2, is arranged with a bearing 4 on described pivot pin, the outer connecting rod 5 that is arranged with of described bearing 4; On described the first bent axle piece 1, an end is provided with the first connecting shaft 6, and described the first connecting shaft 6 ends are provided with the first connecting head 7, and described the first connecting head 7 is provided with outside thread; On described the second bent axle piece 2, an end is provided with the second connecting shaft 8, described the second connecting shaft 8 ends are provided with the second connecting head 9, described the second connecting head is provided with outside thread, and described the second connecting shaft dwindles to the second connecting head external diameter cascade, also be provided with a draw-in groove 10 on described the second connecting shaft, described the second connecting head end also is provided with a strut 11; Hole 13 is corrected in described the first bent axle piece be provided with first rectification hole 12 and second relative to the second bent axle piece central axis position; Described first corrects hole 12 and second corrects hole 13 one section cylinder hole section that internal surface is smooth of existence.
The utility model is consistent with the internal combustion engine crank shaft assembly of existing technology in use, just when the verification coaxality, thereby can realize the rectification of combustion motor Y-axis by testing the first error of correcting hole 12 and the second rectification hole 13 inwalls circle central axis, effect is apparent in view.
Thereby the beneficial effects of the utility model are to realize by testing the first error of correcting hole and the second rectification hole inwall circle central axis the rectification of combustion motor Y-axis, verification is got up extremely low to the equipment requirement,, as long as a T-shaped probe that can stretch gets final product the verification coaxality, adjust easily simultaneously.
