Abstract
Oil blanket of usheing to seat, it is constituteed including oil blanket seat, metal framework. The oil blanket seat is equipped with oil blanket hole, locating hole, mounting hole, oil blanket hole one side arch has rubber, and rubber is formed with dust lip and seal lip, the downthehole rubber that is equipped with of oil blanket, rubber is formed with dust lip and seal lip, the metal framework that tells of institute describes for the ring admittedly, connects the opposite side that has rubber in oil blanket hole arch, rubber, dust lip and seal lip bond on the oil blanket seat, the working face of seal lip sets up the screw thread line. Take behind the bent axle of oil blanket seat the oil blanket assembly easily the installation with demolish, failure analysis carried out to the turning test machine to installation that can be once more, reduce since repeated installation with demolish the damage of oil blanket in -process to the oil blanket substance.
Description
Technical field
The utility model belongs to seal arrangement, and particularly one is usherd to seat oil sealing.
Background technique
General crank shaft oil seal needs to be arranged in oil sealing bore, then is assembled on engine crankshaft by whole oil sealing base.Need be arranged on oil sealing base, operation is many.After installation, easily there is the phenomenon of leakage of oil in oil sealing place.Therefore, we need oil sealing again to remove; In the process of removing, easily cause the deformation and damage of oil sealing, causing producer like this cannot be installed on rotation test machine by described oil sealing again, verifies the quality problems of oil sealing.
Summary of the invention
For solving the problem, the utility model provides oil sealing of usheing to seat.The crankshaft rear oil seal assembly composition of described band oil sealing base comprises oil sealing base, metal frame.Oil sealing base is provided with oil sealing hole, positioning hole, mounting hole; Oil sealing hole side is raised with rubber, and rubber is formed with dust excluder lips and sealing lip; Be provided with rubber in oil sealing hole, rubber is formed with dust excluder lips and sealing lip; Institute's metal frame of telling, admittedly for circular, is connected to the opposite side that oil sealing hole is raised with rubber; Described rubber, dust excluder lips and sealing lip are bonded on oil sealing base; The working surface of described sealing lip arranges threaded line.Further, the crankshaft rear oil seal assembly of described band oil sealing base, its oil sealing hole be raised with rubber opposite side install metal frame, metal frame is fixed by bolts on oil sealing base.In order to the oil sealing in the crankshaft rear oil seal assembly of check strap oil sealing base is in the sphere of activities of installing or in demolishing process, described metal frame is close to the rubber in oil sealing hole and metal frame inner ring radius is greater than axle radius 2mm-4mm.
Further, oil sealing, under the restriction of oil sealing base and metal frame, is installed or decreases the substantive damage to oil sealing in demolishing process, again can be installed to rotation test machine and carry out demonstration test, reducing producer and claim damages inefficacy oil sealing.
Relative to prior art, the beneficial effects of the utility model are:
1. the utility model, oil sealing and oil sealing base are removed as a whole, can reduce the dismounting difficulty of oil sealing.
2. the utility model, the opposite side that sealing of hole is raised with rubber is provided with metal frame, can repeatedly remove oil sealing, and does not cause substantial damage to oil sealing.
3. the utility model, oil sealing again can be installed to rotation test machine and carry out demonstration test.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crankshaft rear oil seal assembly of band oil sealing.
Embodiment
Embodiment 1
Usher to seat oil sealing, its composition comprises oil sealing base, metal frame.Oil sealing base is provided with oil sealing hole, positioning hole 4, mounting hole 1 and mounting hole 3; Oil sealing hole side is raised with rubber 2, and rubber 2 is formed with dust excluder lips and sealing lip; Be provided with rubber 2 in oil sealing hole, rubber 2 is formed with dust excluder lips and sealing lip; Institute's metal frame of telling, admittedly for circular, is connected to the opposite side that oil sealing hole is raised with rubber 2; Described rubber 2, dust excluder lips and sealing lip are bonded on oil sealing base.Above-mentioned model utility is provided with 5 mounting holes 1 for the crankshaft rear oil seal assembly of band oil sealing base is arranged on pedestal; Be provided with 8 mounting holes 3 for metal frame is fixed on oil sealing base; Be provided with installation or the dismounting of the crankshaft rear oil seal assembly of 2 positioning holes 4 convenient band oil sealing base.
In the utility model, rubber 2 is in dismounting, and the sphere of activities perpendicular to axial direction is limited to 2mm to 4mm by metal frame, decreases oil sealing substantial damage to oil sealing in demolishing process.Oil sealing under can again removing herein is like this installed on rotation test machine and carries out demonstration test.
Claims (2)
