Abstract
The utility model discloses a split self-positioning connecting rod, which comprises a connecting rod body. The connecting rod body consists of a crank mounting seat and a connecting rod cover which are mounted together, a first combination surface and a second combination surface are disposed among two ends of the crank mounting seat and two ends of the connecting rod cover, a first pair of arc-shaped positioning jaws is arranged on the first combination surface, a second pair of arc-shaped positioning jaws is disposed on the second combination surface, the first pair of positioning jaws is not concentric to the second pair of positioning jaws, and each pair of positioning jaws consists of arc positioning convex teeth and an arc positioning concave groove which match with each other. The arc positioning convex teeth and the arc positioning concave grooves which match with each other are disposed on the combination surfaces of the connecting rod, and can simultaneously restrain radial movement and axial movement of the crank mounting seat and the connecting cover along a crank hole, load-bearing capacity, shearing resistance and assembly quality are higher, simultaneously the first pair of positioning jaws is not concentric to the second pair of positioning jaws so that relative rotation between the crank mounting seat and the connecting rod cover is avoided, and positioning effect is guaranteed.

Technical field
The utility model relates to the engine fittings field, relates in particular to a kind of connecting rod.
Background technique
Connecting rod comprises and is positioned at crank hole that connecting rod shank one end forms by crank fitting seat and connecting rod cap and the piston pin hole that is positioned at the connecting rod shank the other end, connecting rod is located between piston and the bent axle, with the stressed bent axle that passes to of piston, thereby make the to-and-fro motion of piston change rotatablely moving of bent axle into.Connecting rod is bearing very high periodic shock power, bending force and inertial force in the course of the work.This just requires connecting rod to have high intensity, toughness and fatigue behaviour.The crank fitting seat of existing connecting rod and the location tooth embedding between the connecting rod cap, only can retrain crank fitting seat and connecting rod cap along described crank hole moving radially, to the required precision height of screw between crank fitting seat and the connecting rod cap, Location accuracy is poor, has influenced the performance of connecting rod.
The model utility content
Technical problem to be solved in the utility model provides a kind of bearing capacity, shear resistance is strong, and the higher self-align connecting rod of split of assembly quality.
For solving the problems of the technologies described above, the technical solution of the utility model is: the self-align connecting rod of split, comprise connecting rod shank, one end of described connecting rod shank is provided with the crank fitting seat, on the described crank fitting seat connecting rod cap is installed, described crank fitting seat and described connecting rod cap form the crank hole of connecting crank, the other end of described connecting rod shank is provided with the piston pin hole that connects piston, be provided with first junction plane and second junction plane between described crank fitting seat and the described connecting rod cap two end part, described first junction plane is provided with first pair of location tooth embedding, described second junction plane is provided with second pair of location tooth embedding, described first pair of location tooth embedding and described second pair of location tooth embedding are circular arc, described first pair of location tooth embedding and described second pair of location tooth embedding decentraction, described first pair of location tooth embedding and described second pair of location tooth embedding comprise that the circular arc that cooperatively interacts locatees protruding tooth and circular arc positioning groove.
As optimized technical scheme, described first pair of location tooth embedding and described second pair of location tooth embedding are the tooth embedding of dome arc location, and the center of circle of two pairs of described dome arc location tooth embeddings lays respectively at the outside of described connecting rod shank.
Owing to adopted technique scheme, the self-align connecting rod of split, comprise connecting rod shank, one end of described connecting rod shank is provided with the crank fitting seat, on the described crank fitting seat connecting rod cap is installed, described crank fitting seat and described connecting rod cap form the crank hole of connecting crank, the other end of described connecting rod shank is provided with the piston pin hole that connects piston, be provided with first junction plane and second junction plane between described crank fitting seat and the described connecting rod cap two end part, described first junction plane is provided with first pair of location tooth embedding, described second junction plane is provided with second pair of location tooth embedding, described first pair of location tooth embedding and described second pair of location tooth embedding are circular arc, described first pair of location tooth embedding and described second pair of location tooth embedding decentraction, described first pair of location tooth embedding and described second pair of location tooth embedding comprise that the circular arc that cooperatively interacts locatees protruding tooth and circular arc positioning groove; The connecting rod junction plane is provided with the circular arc that cooperatively interacts and locatees protruding tooth and circular arc positioning groove, can retrain simultaneously crank fitting seat and connecting rod cap along described crank hole radially move and along axial the moving of described crank hole, bearing capacity, shear resistance and assembly quality are higher, described first pair of location tooth embedding of circular arc simultaneously and described second pair of location tooth embedding decentraction, avoid relatively rotating between crank fitting seat and the connecting rod cap, guaranteed locating effect.
