Abstract
The utility model discloses a kind of sprocket wheel axle construction for preventing from skidding, sprocket shaft (4) is connect with sprocket wheel (1), sprocket wheel (1) is equipped with sprocket hole (2), the shape of sprocket hole (2) are as follows: a part of its side is the anti-rotation plane (3) of rectangle；On the cross section of sprocket hole (2), curved portion and straight line portion, straight line portion are the string on circle to sprocket hole (2) respectively, and curved portion is the major arc on circle；Sprocket wheel (1) covers on sprocket shaft (4)；The shape of sprocket shaft (4) and the shape of sprocket hole (2) are adapted and form cooperation.By adopting the above technical scheme, it is arranged to distinctive structure by centre of sprocket hole and with the sprocket shaft of its this cooperation, prevents sprocket wheel from skidding on sprocket shaft rotation；This mode structure is simple, at low cost.
Description
Technical field
The utility model belongs to the technical field of Vehicle Engine Structure design and development, is related to timing of engine system
System.More specifically, the utility model relates to a kind of sprocket wheel axle construction for preventing from skidding.
Background technique
Sprocket wheel guarantees sprocket wheel by the clearance fit of size in engine operation rotation, to influence engine at present
Performance.The sprocket gear size requirement of this mode is more stringent, and processing is more stringent, thus increased costs.
Utility model content
The utility model provide it is a kind of prevent skid sprocket wheel axle construction, the purpose is to prevent sprocket wheel on sprocket shaft from
Turn.
To achieve the goals above, the technical solution that the utility model is taken are as follows:
The sprocket wheel axle construction for preventing from skidding of the utility model, the sprocket shaft are connect with sprocket wheel, and the sprocket wheel is set
There are sprocket hole, the shape of the sprocket hole are as follows: a part of its side is the anti-rotation plane of rectangle；In the sprocket hole
On cross section, the sprocket hole difference curved portion and straight line portion, the straight line portion are the string on circle, the song
Line part is the major arc on circle；The chain wheel case is on the sprocket shaft；The shape of the sprocket shaft and sprocket hole
Shape is adapted and forms cooperation.
The arc transition that the string and arc intersection is R0.5.
The intersection of the sprocket hole and end plane is the arc transition of R0.5.
The diameter of the sprocket hole circular arc camber part is Φ 12mm.
The utility model by adopting the above technical scheme, is arranged to peculiar by centre of sprocket hole and with the sprocket shaft of its this cooperation
Structure, prevent sprocket wheel from skidding on sprocket shaft rotation；This mode structure is simple, at low cost.
Detailed description of the invention
Label is briefly described as follows in content and figure shown in attached drawing:
Fig. 1 is the chain sprocket structure schematic diagram in the utility model；
Fig. 2 is the schematic diagram of the amplification of the part A in Fig. 1；
Fig. 3 is the structural schematic diagram of the sprocket shaft in the utility model.
In the figure, it is marked as
1, sprocket wheel, 2, sprocket hole, 3, anti-rotation plane, 4, sprocket shaft, 5, cut flat face.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, with help those skilled in the art to the inventive concept of the utility model, technical solution have it is more complete, accurate and
Deep understanding.
The structure of the utility model as shown in Figure 1, Figure 2 and Figure 3, it is described for a kind of sprocket wheel axle construction for preventing from skidding
Sprocket wheel 1 is equipped with sprocket hole 2.
In order to overcome the shortcomings of the prior art, realizing the goal of the invention for preventing sprocket wheel rotation on sprocket shaft, this reality
With the novel technical solution taken are as follows:
As shown in Figure 1, Figure 2 and Figure 3, the sprocket wheel axle construction for preventing from skidding of the utility model, the sprocket shaft 4 and chain
1 connection of wheel, the shape of the sprocket hole 2 are as follows: a part of its side is the anti-rotation plane 3 of rectangle；In the sprocket hole 2
Cross section on, the sprocket hole 2 distinguishes curved portion and straight line portion, and the straight line portion be the string on justifying, described
Curved portion be circle on major arc；It is characterized by: described 1 set of sprocket wheel on the sprocket shaft 4；The sprocket shaft
4 shape and the shape of sprocket hole 2 are adapted and form cooperation.
Centre of sprocket hole is arranged to distinctive structure by the mode for preventing sprocket wheel rotation of the utility model；This mode knot
Structure is simple, at low cost.
The particular technique parameter of the utility model are as follows:
The arc transition that the string and arc intersection is R0.5.
The arc transition that the intersection of the sprocket hole 2 and end plane is R0.5.
The diameter of the 2 circular arc camber part of sprocket hole is Φ 12mm.
Above-mentioned technical parameter can satisfy the technical requirements of automobile engine totality.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
