Abstract
The utility model discloses a kind of Combined unmanned machine crankshaft groups, include a crankshaft main body and a crankshaft mold insert, the crankshaft mold insert is separably connected with the crankshaft main body, the crankshaft main body is equipped with a seal mounting hole, one crankshaft mold insert mounting hole and a first longitudinal direction pin hole, one end of the crankshaft mold insert is equipped with an axial center hole and a second longitudinal direction pin hole, the crankshaft mold insert and the crankshaft mold insert mounting hole are connected by interference fit and form the oil sealing mounting groove of a left side direction, one pin passes through interference fit with the first longitudinal direction pin hole and second longitudinal direction pin hole, oil sealing is installed in the oil sealing mounting groove.Due to being closed after individually being processed using crankshaft and crankshaft mold insert by pin bank, the mode that oil sealing is installed after the sealing structure of direction on the left of being formed realizes operating, the requirement of unmanned plane crankshaft seal design is met while enhancing the sliding torque between crankshaft mold insert and crankshaft, it is fabricated simply, and practicability is good.
Description
Technical field
The utility model relates to a kind of unmanned planes, more precisely, being a kind of Combined unmanned machine crankshaft group.
Background technique
Crankshaft group is that engine realizes working cycles, completes the important moving component of energy conversion.In the prior art, nothing
It is man-machine to be integrated with crankshaft, it which is provided with two cranks and two crank throw structures, pass through two crank throws and crank bar portion structure
Cooperate with exterior part, realizes operating.Deficiency in the prior art is: bent for there is the unmanned machine crankshaft of seal request
Shank portion must be provided with the oil sealing installation slot structure of left side direction, still, the court on the left of the crank bar portion processing of integral piece crankshaft
To oil enveloping structure mode it is limited, oil enveloping structure cannot cause not to be able to satisfy Seal Design requirement, need by completing the process
It is improved from design.
Utility model content
The utility model mainly solves technical problem present in the prior art, to provide a kind of Combined unmanned machine
Use crankshaft group.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of Combined unmanned machine crankshaft group, which is characterized in that the Combined unmanned machine crankshaft group packet
Containing a crankshaft main body and a crankshaft mold insert, the crankshaft mold insert is separably connected with the crankshaft main body, described
Crankshaft main body is equipped with a seal mounting hole, a crankshaft mold insert mounting hole and a first longitudinal direction pin hole, the crankshaft mold insert
One end is equipped with an axial center hole and a second longitudinal direction pin hole, and the crankshaft mold insert passes through with the crankshaft mold insert mounting hole
Interference fit connects and is formed the oil sealing mounting groove of a left side direction, a pin and the first longitudinal direction pin hole and second longitudinal direction pin
Hole is equipped with oil sealing in the oil sealing mounting groove by being interference fitted.
The Combined unmanned machine of the utility model is had the advantage that with crankshaft group due to using crankshaft and crankshaft mold insert
It is individually closed after processing by pin bank, the mode that oil sealing is installed after the sealing structure of formation left side direction realizes operating, enhances song
The requirement of unmanned plane crankshaft seal design, processing and manufacturing letter are met while sliding torque between axis mold insert and crankshaft
Single, practicability is good.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the schematic perspective view of the Combined unmanned machine crankshaft group of the utility model；
Fig. 2 is the attachment structure schematic diagram of the Combined unmanned machine crankshaft group in Fig. 1；
Fig. 3 is the attachment structure schematic diagram of the Combined unmanned machine crankshaft group in Fig. 1, is at this time assembled state.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
As shown in Figure 1 to Figure 3, which includes a crankshaft main body 1 and a crankshaft mold insert 2 with crankshaft group,
The crankshaft mold insert 2 is separably connected with the crankshaft main body 1, which is equipped with a seal mounting hole 7, a crankshaft
One end of mold insert mounting hole 8 and a first longitudinal direction pin hole 9, the crankshaft mold insert 2 is equipped with an axial center hole 5 and a second longitudinal direction pin
Hole 6, the crankshaft mold insert 2 and the crankshaft mold insert mounting hole 8 are connected by interference fit and form the oil sealing installation of a left side direction
Slot 10, a pin 3, by being interference fitted, are equipped with the first longitudinal direction pin hole 9 and second longitudinal direction pin hole 6 in the oil sealing mounting groove 10
Oil sealing.
Due to being closed after individually being processed using crankshaft and crankshaft mold insert by pin bank, pacify after forming the sealing structure of left side direction
The mode of charge of oil envelope realizes operating, and unmanned machine crankshaft is met while enhancing the sliding torque between crankshaft mold insert and crankshaft
The requirement of Seal Design, processing and manufacturing is simple, and practicability is good.
Not limited to this, any change or replacement expected without creative work should all be covered in the utility model
Protection scope within.Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
