Abstract
The utility model is a kind of diesel engine oil pan of vibration and noise reducing, including oil sump housing, the inner chamber body of the oil sump housing includes deep cavity, shallow cavity body, without interval between deep cavity and shallow cavity body, shallow cavity body sidewall is provided with fuel feed hole, and deep cavity bottom is provided with oil outlet, and oil sump housing upper has overhanging oil sump side, oil sump side is equipped with bolt hole, and oil sump housing internal layer is that foam aluminium alloy casting shell, outer layer are the heat-resisting sound insulating layers of high temperature resistant.Beneficial effect：By the use of structural member of the foam aluminium alloy as oil sump is cast, the weight of existing oil sump can be effectively reduced.Using foam aluminium alloy damping characteristic and and the unconfinement type vibration-proof structure of foam aluminium alloy and macromolecule damping rubber, can effectively weaken the vibration of diesel engine, reduce the noise of engine.
Description
Technical field
It the utility model is related to diesel-engine equipment field, and in particular to a kind of diesel engine oil pan of vibration and noise reducing.
Background technology
Diesel engine has high compression ratio, and the high thermal efficiency, has high dynamic property and economy, power bracket
Extensively, size is small light-weight, and mobility is good, and reliability is high, long lifespan, is widely used in some farm machineries, on heavy-duty machinery, but
It is to restrict it to lead to be applied high mainly due to its fuel efficiency, shock loading is big, causes that its vibration is big, and noise is ear-piercing；
At present, the oil sump as one of diesel engine critical piece, mainly by aluminium alloy or cold-rolling steel-plate punch
Form, or aluminium alloy or cast steel casting form, these materials are although easy to process, of low cost, but weight is big, subtract
Effect of shaking is bad, it is impossible to effectively reduces the noise of diesel engine.
Utility model content
The purpose of this utility model is to provide a kind of diesel engine oil pan of vibration and noise reducing, to solve existing oil sump weight
Greatly, the technical problem of effectiveness in vibration suppression difference.
For this reason, the utility model adopts the following technical solution：A kind of diesel engine oil pan of vibration and noise reducing, including oil sump
Housing, the inner chamber body of the oil sump housing includes deep cavity, shallow cavity body, without interval, shallow cavity body between deep cavity and shallow cavity body
Side wall is provided with fuel feed hole, and deep cavity bottom is provided with oil outlet, and oil sump housing upper has an overhanging oil sump side, on oil sump side
Equipped with bolt hole, for oil sump housing exterior walls by having two layers, internal layer is that foam aluminium alloy casting shell, outer layer are the heat-resisting sound insulation of high temperature resistant
Layer.Foam aluminium alloy casting shell is cast by melt casting method.
Preferably：The heat-resisting sound insulating layer of high temperature resistant is macromolecule damping rubber layer, is bonded by high temperature resistant binder
Outside foam aluminium alloy casting shell.
The beneficial effects of the utility model are：
（1）By the use of structural member of the foam aluminium alloy as oil sump is cast, the weight of existing oil sump can be effectively reduced.
（2）Utilize the damping characteristic and and the unconfinement type of foam aluminium alloy and macromolecule damping rubber of foam aluminium alloy
Vibration-proof structure, can effectively weaken the vibration of diesel engine, reduce the noise of engine.
