Description
Technical field
The utility model belongs to mechanical fitting technical field, is related to a kind of connecting rod, in particular to a kind of link assembly.
Background technique
Connecting rod is a kind of middle transition part for connecting piston and crankshaft, active force suffered by piston can be transmitted to crankshaft, will
The reciprocating motion of piston is changed into the rotary motion of crankshaft, and link assembly is usually served as a contrast by gonnecting rod body, connecting rod cap, small end of connecting rod
The composition such as set, big end bearing shell and connecting-rod bolts, connection rod set bears the gas load that piston pin transmits and itself swings
With the effect of piston group reciprocal inertia force, the size and Orientation of these power be all it is periodically variable, therefore connecting rod compressed,
Alternate load effects, the connecting rods such as stretching are mainly used in engine, and the main movement machine for constituting engine is combined with crank
Structure.
Link assembly on existing market in order to realize the low friction of connecting rod in the running, be usually all by bearing shell come
It crosses, has the characteristics that cheap, structure is simple, but since bearing shell is all relatively thin in fabrication design, when link assembly is in
When the operating of high intensity, bearing shell can be because of stronger impact so that itself generation deformation, leads to the feelings for being likely to occur unbalance stress
The disadvantages of condition occurs, so that the whole degree of wear is inconsistent, has service life short, replacement trouble.
Summary of the invention
The purpose of this utility model be for the above-mentioned problems in the prior art, provide a kind of long service life,
Easy to maintain, the reasonable link assembly of design.
The purpose of this utility model can be realized by the following technical scheme: a kind of link assembly, including the body of rod and bar
Set, the body of rod is matched with rod set is formed with accommodating chamber, bearing retainer is provided in the accommodating chamber, feature exists
In the upper and lower ends of the bearing retainer offer fitting groove, are provided in the fitting groove for realizing bearing guarantor
Hold the locking mechanism that frame is mutually fixed with the body of rod, rod set, the locking mechanism includes locking push rod, clamping block and can assembled
The locking roller of horizontal sliding in slot, the side of the bearing retainer offers the push rod channel for locking push rod insertion, described
The tail end in push rod channel has to be set at access port with the access port that is connected outside fitting groove, the clamping block, one
End is located in push rod channel, and the other end is located at the outside of access port, and the middle part of the locking push rod to be formed with being recessed inwardly
Mating groove, the mating groove are caught in for clamping block inboard portion, the body of rod, rod set position corresponding with fitting groove
The place of setting is caught in the lock slots of locking with the plate rail slided for locking roller and for locking roller.
The technical effect of this link assembly are as follows: link assembly is formed using detachable form, is not dismounting the body of rod and bar
In the case where set, bearing retainer can be realized by locking mechanism and flexibly, quickly be installed, and locking mechanism includes locking push rod,
Clamping block and locking roller when locking roller inwardly slides into along plate rail, eventually stop in lock slots, are then pushed away by locking
The movement of bar rotates clamping block, so that clamping block exterior portion is resisted against locking roller and realizes bearing retainer and bar with this
Body, rod set it is relatively fixed.
In a kind of above-mentioned link assembly, transverse groove, the locking roller are offered on the end wall of the fitting groove two sides
Both ends there is the sliding block that matches with transverse groove.It prevents locking roller from occurring the phenomenon that clamping stagnation during sliding, improves
The fluency of operation.
In a kind of above-mentioned link assembly, has in the outer end wall at left and right sides of the bearing retainer and be recessed inwardly
It rises as high as the banks.Bearing retainer and the quick prepackage of the body of rod, rod set is facilitated to cooperate.
In a kind of above-mentioned link assembly, it is provided on the binding site at the rod set both ends for being inserted into the body of rod
The connecting column in portion is connected with fixing bolt between the connecting column and the body of rod.Improve the body of rod and rod set assembly stability with
Fastness.
In a kind of above-mentioned link assembly, the tail end in the push rod channel has thread segment, described to lock the outer of push rod
The motion thread matched with thread segment screw thread is machined on surface.Only thread segment is arranged in the tail end in push rod channel, facilitates lock
The installation for determining push rod is fixed.
Compared with prior art, this link assembly replaces bearing shell using bearing retainer, and it passes through locking mechanism reality
It now flexibly, quickly installs, so that link assembly integrally has the advantages that long service life, easy to maintain, design is reasonable.
