Guide hole is put, the openend of gland can be set on positioning disk；And
Bolt, when positioning disk is fixed on the end face of bent axle and the openend of gland is set on positioning disk, the spiral shell of bolt
Post can pass through the guide hole of gland to arrive in the screwed hole of positioning disk and is threadedly coupled with screwed hole, and the nut pressure holding pressure of bolt
Set makes gland drive pressure ring to follow the stud of bolt to move, so that pressure ring pressure holding oil sealing realizes press fitting of the oil sealing on bent axle.
As the further improvement of such scheme, the bulge loop coaxial with gland be set on the outer wall of gland, on bulge loop with pressure
The surface of ring the same side is confined planes.
Further, bulge loop and gland are formed in one structure.
As the further improvement of such scheme, bulge loop and gland are formed in one structure.
As the further improvement of such scheme, fastener is screw.
It is rounded as the further improvement of such scheme, positioning disk.
As the further improvement of such scheme, positioning disk is fixed on the end face of bent axle and the openend of gland is set in
When on positioning disk, pressure ring is with regard to pressure holding on oil sealing.
The utility model meets the oil sealing installation of the bent axle of end face unthreaded hole, while the more common press mounting tool of efficiency is high,
Certainly efficiency is somewhat low compared with special charge of oil seals pressing machine, but during online assembling rear end crankshaft center can be met without internal thread
The installation of the crankshaft rear oil seal in hole, and possess the characteristics of light, easy to operate, cost is low.
Brief description of the drawings
Fig. 1 cuts open for the application structure of the oil seal pressing instrument of the bent axle of the present utility model for center unthreaded hole to be shown
Figure.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Designed referring to Fig. 1, oil seal pressing instrument of the present utility model is the bent axle 7 for being directed to center unthreaded hole, it is bent
Envelope 8 of draining the oil is covered on the end face of axle 7 in advance, oil sealing 8 is enclosed on bent axle 7 and waits to be pressed.
Oil seal pressing instrument includes gland 1, fastener 2, positioning disk 3, bolt 4.The centrally disposed screwed hole 6 of positioning disk 3,
Positioning disk 3 is preferably with circle.
Fastener 2 is used for the end face that positioning disk 3 is fixed on to the bent axle 7 for covering envelope 8 of draining the oil in advance, and fastener can be
Screw or bolt.
One end of gland 1 is that pressure ring 9 is set on openend and end face, and its opposite other end is blind end and end face center is set
Guide hole is put, the openend of gland 1 can be set on positioning disk 3.It can be set on the outer wall of gland 1 and coaxial convex of gland 1
Ring 10, the surface on bulge loop 10 with the same side of pressure ring 9 is confined planes 5.Bulge loop 10 is preferably integrally formed in the openend of gland 1
On end face, it is formed in one structure with gland 1, bulge loop 10 can also be formed in one structure with gland 1.
When positioning disk 3 is fixed on the end face of bent axle 7 and the openend of gland 1 is set on positioning disk 3, the pressure holding of pressure ring 9
On oil sealing 8, the stud of bolt 4 can pass through the guide hole of gland 1 arrive in the screwed hole 6 of positioning disk 3 and with the screw thread of screwed hole 6
Connection, and the nut pressure holding gland 1 of bolt 4 makes gland 1 drive pressure ring 9 to follow the stud movement of bolt 4 to remove pressure holding oil sealing 8 with reality
Existing press fitting of the oil sealing 8 on bent axle 7.
Pressure ring 9 on oil sealing 8, can also can exist in ability pressure holding during gland 1 is close to bent axle 7 in pressure holding at the very start
On oil sealing 8.
Positioning disk 3 is connected with the end face of bent axle 7 by lag bolt 2, positioning disk 3 by modifier treatment surface by processing with
The rear end face of bent axle 7 is harmonious.Oil sealing 8 is first mounted on bent axle 7.Gland 1 is mounted on bent axle 7 by the positioning of positioning disk 3, so
Gland 1 is connected with positioning disk 3 with bolt 4 afterwards.When rotating bolt 4, bolt 4 acts on power on positioning sleeve 3, drives gland
1 moves downward, so that oil sealing 8 is pressed downwards.When the confined planes 5 of gland 1 reach flywheel shell surface, oil sealing 8 is press-fit into place, complete
Into the oil seal pressing of the bent axle 7 of rear end face non-stop layer internal thread hole.
The utility model replaces the end face center internal thread of bent axle 7 using a positioning disk 3 in middle tapped hole
Hole, the depth of this screwed hole and the thickness of positioning disk 3 can adjust as needed.Fastener 2 is used simultaneously by positioning disk 3 and song
The end face connection of axle 7.Positioning disk 3 has higher hardness, Surface Machining by modifier treatment.Gland 1 is fixed with positioning sleeve 3
Position, oil sealing 8 is placed on the front end of the confined planes 5 of the leading portion of gland 1, is connected gland 1 with positioning disk 3 by bolt 4.Limiting stand
The confined planes 5 of rank are requiring to reach 1.6 by working process roughness.The limited step (i.e. bulge loop 10) of gland 1 can be according to need
Seek design.Gland 1 and the joint face Quenching Treatment of bolt 4, increase the wearability of gland, and service life.Such the utility model
Technical ability meets the oil sealing installation of the bent axle 7 of rear end non-stop layer screwed hole in use.
The utility model can optimize design according to each enterprise product type, instrument is adapted to all products of this enterprise
The requirement used.
