Description
Technical field
A kind of transmission oil envelope assembly tool is the utility model is related to, is specially a kind of transmission input shaft oil seal pressing work
Dress.
Background technology
In the speed changer of automobile etc., prevent the fluids such as oil from protruding from outside speed changer using transmission input shaft oil sealing
The end leakage of the human transporting axle of shell to outside.
Transmission input shaft oil sealing is that vertical press fitting is installed in the oil sealing installation notch of speed changer, to be interference fitted,
It is required that oil sealing is vertically flattened in transmission input shaft oil sealing installation notch, oil sealing is not allowed to occur deforming and damage.Speed change at present
Device input shaft oil seal press-fitting tool easily damages oil sealing when assembling oil sealing, deforms oil sealing, and in assembling speed changer input
When shafting oil seals, due to artifact, the anti-loaded situation of input shaft oil seal is happened occasionally, input shaft oil seal is anti-loaded, causes speed change
The parts such as device and oil sealing damage and other parasitic losses.
The content of the invention
For in the prior art the defects of, the utility model provides a kind of work of transmission input shaft oil seal pressing, it is tied
Structure is simple and convenient to operate, oil sealing assembling quality it is good, anti-loaded from source prevention oil sealing, avoid oil sealing it is anti-loaded caused by parts
Damage and parasitic losses.
Technical solutions of the utility model are as follows:
A kind of transmission input shaft oil seal pressing frock, its key are：Including lead, the oil sealing sequentially coaxially connected
It is pressed disk and lever；The lead includes sequentially connected path section and major diameter section；The oil seal pressing disk is more than for diameter
The lead major diameter section diameter it is discoid, and be arranged circumferentially four along it in the oil seal pressing disk lower surface
Needle roller, the needle roller protrude from the oil seal pressing disk outer surface.
When being pressed U-shaped oil sealing, first by oil sealing assembling in frock described in the utility model.When oil sealing correctly assembles, U
Type oil sealing accommodates thimble, and under the action of oil sealing ring spring, the main lip of oil sealing is contradicted in the major diameter section outer surface of lead, from
And make it that oil sealing is correctly spacing, last vertical percussion lever end face exerts a force lever end face, so that oil seal pressing disk stress passes
Oil sealing is delivered to, makes oil sealing uniform stressed, oil is completed so as to oil sealing is correctly pressed into the oil sealing installation notch of transmission input shaft
The press fitting of envelope.Because oil sealing is correctly spacing, frock force surface and oil sealing stress surface are adapted, and external force direction perpendicular to force surface and
Stress surface, ensures to avoid oil sealing damage, deformation while oil sealing assembly precision.
Designed additionally by said mechanism, when assembling oil sealing, if oil sealing is anti-loaded, oil sealing plane is limited to thimble, oil sealing
Radially nothing puts forth effort to cause oil sealing free dropping, so that assembler has found that oil sealing is anti-loaded easily.Effective pre- preventing oil seal is anti-loaded,
Avoid oil sealing it is anti-loaded caused by parts damage and parasitic losses, from source play the role of assembling prevention.
During oil sealing is pressed into oil sealing installation notch, lead path section has the function that to be oriented to and positions, and is used for
Ensure the verticality of oil seal pressing.
Further, the lead, oil seal pressing disk, lever are structure as a whole.
Further, the path section of the lead and major diameter section pass through the round and smooth connection of a changeover portion.
Further, it is equipped with chamfer mechanism in the end of the lead path section.
Further, the lever is cylinder, and disk is also connected with the lever bottom, the disk and the oil
Envelope press fitting disk is coaxially connected, and has a diameter larger than the diameter of oil seal pressing disk.By said structure, the lever will by disk
Stress passes to oil seal pressing disk so that oil seal pressing disk is more uniformly stressed, and is further ensured that assembly precision.

Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiments are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality cannot be limited with this
New protection domain.
Transmission input shaft oil seal pressing frock as shown in Figure 1, including sequentially coaxially connect lead 1, oil sealing pressure
Sabot 2 and lever 3；The lead includes sequentially connected path section 11 and major diameter section 12；The path section 11 and major diameter section
12 pass through 13 round and smooth connection of changeover portion；The oil seal pressing disk 2 is more than the disk of 12 diameter of lead major diameter section for diameter
Shape, and four needle rollers 4 have been arranged circumferentially along it in 2 lower surface of oil seal pressing disk, the needle roller protrudes from described
2 lower surface of oil seal pressing disk.
When being pressed U-shaped oil sealing 5, oil sealing 5 is assembled in frock described in the utility model first.As shown in Fig. 2, oil sealing
During 5 correct assembling, U-shaped oil sealing accommodates thimble 4, and under the action of ring spring 51, the main lip 52 of oil sealing is contradicted in lead
Major diameter section outer surface, so that oil sealing 5 is correctly spacing, last vertical percussion lever 3, exerts a force lever 3, oil seal pressing disk 2
Stress is delivered to oil sealing 5, makes 5 uniform stressed of oil sealing, so that oil sealing 5 to be correctly pressed into the oil sealing installation notch of transmission input shaft
The interior press fitting for completing oil sealing.As shown in figure 3, during assembling oil sealing 5, if oil sealing 5 is anti-loaded, oil sealing plane is limited to thimble 4, oil sealing
5 radial directions are without putting forth effort to cause oil sealing free dropping.By the design of said structure, effective pre- preventing oil seal is anti-loaded, avoids oil sealing dress
Parts damage and parasitic losses caused by anti-, play the role of assembling prevention from source.
Chamfer mechanism 11a is equipped with the end of the lead path section.The lever 3 is cylinder, at 3 bottom of lever
Portion is also connected with disk 6, and the disk 6 and the oil seal pressing disk are coaxially connected, and have a diameter larger than oil seal pressing disk
Diameter.By said structure, stress is passed to oil seal pressing disk by the lever by disk so that oil seal pressing disk stress is more
Add uniformly, be further ensured that assembly precision.During oil sealing is pressed into oil sealing installation notch, lead path section 11, which has, to be led
To the effect with positioning, for ensureing the verticality of oil seal pressing.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
