Spheroidal graphite cast-iron is cast, after forging casting is machined, and the crank high to some required precisions carries out grinding again or fine grinding adds
Work.In once low use occasion low to crank required precision or requirement of mechanical strength, the difficult processing of this processing mode
Degree is high, nor is easy to bent axle part to carry out cooperation installation with specific shaft portion.
The content of the invention：
The technical problems to be solved by the invention are：The assembly type crankshaft connecting rod system of reduction difficulty of processing is provided.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of assembly type bent axle connects
Linkage, including first end axle, the second end axle, the first axle bed, the second axle bed, the 3rd axle bed, bent axle, axis and connecting rod, it is described
First end axle and the second end axle are respectively and fixedly installed to two the first axle bed outer ends, and the axis is fixedly mounted on two the 3rd axles
Between seat, the axis of the first end axle, the second end axle and axis three is located on the same line, adjacent one group first
It is fixedly installed between several bent axles, and two bent axles and is fixedly connected by the second axle bed between axle bed and the 3rd axle bed, each
The axis of bent axle is respectively positioned on the face of cylinder coaxial with axis, and the link rotatable is arranged on bent axle.
Preferably, the connecting rod is rotatably installed on bent axle by bearing, and fixation is set on the axis body of the bent axle
It is equipped with bearing positioning sleeve.
Preferably, first axle bed, the second axle bed, the 3rd axle bed are disposed as hooping structure.
Between first end axle, the second end axle and the first axle bed, between the axis and the 3rd axle bed, the bent axle and first
Coordinate to install by flat key keyway arrangements between axle bed, the second axle bed, the 3rd axle bed and fix.
Preferably, being provided with positioning mark on the axis body of the first end axle.
Preferably, being provided with tail end block on the second end axle outer face.
Compared with prior art, usefulness of the present invention is：This toggle by by bent axle, axis, end axle
And axle bed is individually processed, processing technology difficulty and processing cost are reduced, the position high to required precision is ground
More convenient in place with fine grinding, mechanism also has the advantages that easy to assembly in addition, is easy to connecting rod and bearing being arranged on bent
On axle.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the axonometric drawing of schematic structural view of the invention.
