Description
Technical field
The present invention relates to engine component technical field, specially a kind of shockproof thrust clamping device of bearing shell.
Background technology
At present, thrust bearing shell is the internal combustion engines such as diesel engine, gasoline engine and the conventional accessory of some gearings, is also easy
Damage part, with automobile, engineering machinery, agricultural machinery development, the demand of internal combustion engine is increasing, especially heavy-duty car
Use and develop, to the technical requirements more and more higher of thrust bearing shell.At present common thrust bearing shell be mainly overall flanging type and
Fringing riveted.The thrust bearing shell of overall flanging type has the advantages that rigidity is good, installation is convenient, technology acuracy is high, but production
Cost highest, and due to its rigidity characteristic, the distance between two thrust plates is fixed, and the small meeting of the distance between thrust plate
Cause assembling difficult, gap between the distance between thrust plate big end for then reducing thrust shoe and bent axle, radiating effect is bad.Edge
The thrust bearing shell of side riveted, is that the thrust plate that will have convex shoulder is bumped into the groove of thrust bearing shell body end, then carries out riveting
Close and fix, then will artificially be loosened at riveted, be referred to as activating in the industry, so that thrust plate has certain scope of activities in the axial direction, just
In assembling and increase the service life.The final finished cost of this mode of production is more lower slightly than the thrust bearing shell of overall flanging type, but
Technique is complex, and the burr that riveting, activation are produced has to pass through after-treatment, can otherwise influence using effect.Including this
Bearing shell of the flanging type bearing shell in interior some other detachable thrust side is planted, another defect is because riveted operation causes thrust
Piece can not be split after installing with bearing shell body, and some flaws that thrust plate occurs in process of production can cause whole countershaft watt to be reported
It is useless, increase the risk and cost of loss.
The content of the invention
It is an object of the invention to provide a kind of shockproof thrust clamping device of bearing shell, to solve to be proposed in above-mentioned background technology
Problem, had an advantageous effect in that；Concave shape is fixed into using thrust plate and bearing shell to be stuck on thrust main bearing seat, it is to avoid
Because of the risk dropped on thrust plate after pin abrasion, and Shockproof gasket is provided with, improves the reliability of engine.
To achieve the above object, the present invention provides following technical scheme：A kind of shockproof thrust clamping device of bearing shell, including under
Thrust bearing shell and upper thrust bearing shell, the lower thrust bearing shell and upper thrust bearing shell are fixed by screws in bearing cap, and under
Thrust bearing shell and upper thrust bearing shell and the top and bottom that thrust plate is an overall stamping parts, lower thrust bearing shell and upper thrust bearing shell
It is respectively arranged with bayonet socket, lower thrust bearing shell and upper thrust bearing shell are internally provided with Shockproof gasket, and the lower thrust bearing shell is just
The top left and right sides is provided with into oilhole, and the front left and right sides of lower thrust bearing shell is provided with oil-through hole, the upper thrust
The left and right sides of bearing shell is provided with main oily passage, and main oily passage is connected into oilhole.
Preferably, the outside of the bearing cap is provided with housing.
Preferably, it is provided with protective layer on the inside of the lower thrust bearing shell and upper thrust bearing shell.
Preferably, the oil-through hole is semicircle.
Compared with prior art, the beneficial effects of the invention are as follows：Process for machining and manufacturing of the present invention is simple, advantageously reduces and adds
Work cost, convenient disassembly is easy to maintenance, and bearing shell and thrust plate are fixed together with breach by opening, constitutes one
Assembly, registration during assembling and facilitate, after there is abrasion after use, can as needed change wearing part, reduce maintenance
Cost, reliability is high, eliminates the fixing pin of conventional crankshafts thrust plate, and is fixed into concave shape card using thrust plate and bearing shell
On thrust main bearing seat, it is to avoid because of the risk dropped on thrust plate after pin abrasion, and be provided with Shockproof gasket, improve
The reliability of engine.
