Description
Technical field
The utility model relates to a kind of motor link, particularly a kind of crankshaft after oil seal seat.
Background technique
Crankshaft after oil seal seat is as the supporting member of crankshaft of diesel engine main-bearing oil seal, it is attached on the front and rear cover plate of diesel-engine body with screw after loading onto oil sealing again, require crankshaft after oil seal seat to connect reliable, inside and outside circle keeps coaxality, end face and crankshaft hole is installed is kept certain perpendicularity.Complicated structure due to crankshaft after oil seal seat, existing crankshaft after oil seal seat adopts mechanical type mostly, and the mach surface of needs is more, more time-consuming, cost is higher, and many size machinings are not very accurate, can directly have influence on the sealing effect of crankshaft after oil seal seat.
The model utility content
The purpose of this utility model is to overcome that existing crankshaft after oil seal seat design in prior art is complicated, processing trouble, above-mentioned deficiency that cost is higher, provides a kind of simplicity of design, easily manufactured, cost is lower, seal crankshaft after oil seal seat preferably.
In order to realize above-mentioned model utility purpose, the utility model provides following technological scheme:
A kind of crankshaft after oil seal seat comprises hollow body, and described body surface is provided with the mounting hole that body can be connected on diesel-engine body, the described body back side be provided with can be adaptive with crankshaft rear oil seal groove, described body is integrated molding and forming.
Preferably, described body is aluminium alloy castings.
The crankshaft after oil seal seat of integrated injection molding does not need to have reduced production process through just moulding of machining, can be mass, and has improved manufacturing efficiency, has saved cost, has one-body moldedly further alleviated quality, has reduced cost with aluminium alloy castings.
Preferably, mounting hole on described body comprises seven mounting holes, described body comprises annular end and horizontal ends, wherein said annular end surface is provided with six mounting holes, be counterbore one, counterbore two, counterbore three, counterbore four, counterbore five, counterbore six, described horizontal ends bottom surface is provided with two mounting holes, i.e. through hole one, through hole two.
Preferably, described counterbore one, counterbore two, counterbore three, counterbore four, counterbore five, counterbore six are evenly distributed on described annular end surface.
Preferably, be connected with stiffening rib between described counterbore one, counterbore two, counterbore three, counterbore four, counterbore five, counterbore six.
Connection strengthening rib between five counterbores can strengthen the join strength of one-body molded aluminium alloy castings crankshaft after oil seal seat, and when bent axle was worked, crankshaft after oil seal seat connected more firm, not easy oil leakage.
Compared with prior art, the beneficial effects of the utility model:
Crankshaft after oil seal seat described in the utility model by the design integrated injection molding, has reduced machining processes, has improved manufacturing efficient, has saved cost, can manufacture easy accessibility; Five counterbores of crankshaft rear oil seal seating face evenly distribute and between stiffening rib is set, strengthened the installation strength of crankshaft after oil seal seat.
