Description
Technical field
The utility model is related to checknut manufacture field, specifically a kind of wedge-shaped checknut blade.
Background technology
30 ° of wedge-shaped checknuts are currently the standard configuration in Chinese machinery industry, and maximum specification is M39 in professional standard,
But with expanding economy, its screw thread specification, which can not be met, to be actually needed, especially in car industry.
The content of the invention
The utility model designs a kind of wedge-shaped checknut blade, can manufacture application to overcome the deficiencies in the prior art
In the spindle nose and the stop nut at bevel gear position of the compression bearing of the propons, jackshaft and back axle in vehicle key, make these portions
Potential energy reaches good locking effect.
To achieve the above object, a kind of wedge-shaped checknut blade of design, including cutter, blade, it is characterized in that：The knife
Tool is triangular in shape, and one piece of blade is respectively equipped with the triangle of cutter, and the top of the blade is described provided with prominent form of thread
The top of form of thread is provided with tapered ramp, angle is provided between the tapered ramp and the axis of thread, the angle is 30 degree.
The left low right high setting of the tapered ramp.
Centre bore is offered in the middle part of the cutter.
The left and right sides side angle of the form of thread is in 60 degree.
The utility model is compared with the existing technology, simple in construction, easy to use；Do not limited by screw tap specification, threaded
The screw thread of what size；Its tooth form structure be Bottom of Thread have one with the axis of thread into 30 ° of tapered ramp, threaded screw thread has
Good anti-loosening property.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Bottom of Thread in the utility model.
Referring to Fig. 1~Fig. 2, wherein, 1 is cutter body, and 2 be tapered ramp, and 3 be blade, and 4 be centre bore, and 5 be ridge
Type.
Embodiment
The utility model is described further below according to accompanying drawing.
As shown in Fig. 1~Fig. 2, the cutter 1 is triangular in shape, and one piece of blade 3 is respectively equipped with the triangle of cutter 1, described
The top of blade 3 is provided with tapered ramp 2, the tapered ramp 2 provided with prominent form of thread 5, the top of the form of thread 5
Angle is provided between the axis of thread, the angle is 30 degree.
The left low right high setting of tapered ramp 2.
The middle part of the cutter 1 offers centre bore 4.
The left and right sides side angle of the form of thread 5 is in 60 degree.
The utility model by the specification of blade 5 in use, can not be limited, as long as pitch is the same, you can threaded any size
Screw thread, while it is threaded go out thread pitch be 0.5~5mm, screw thread specification be M33 × 1.5mm or M55 × 1.5mm or M60 ×
1.5mm.Also, with it is threaded go out the external screw thread tolerance that is engaged of screw thread be more than 6g.
The utility model blade is in screw cutting, and tooth bottom is braked to be formed with 30 ° of locking inclined-planes, and externally threaded cusp is withstood on
On the tapered ramp of internal thread, very big coupling mechanism force is produced, having reached prevents the purpose of nut loosening.
