Description
Technical field
The utility model belongs to gearing field, more particularly to a kind of anti-dropout spline pair.
Background technology
In industrial production and numerous areas, it is often necessary to which the device of torsion is transmitted in connection between devices, due to spline
Pair has the characteristics that transmission moment of torsion is big, transmission efficiency, positioning accuracy are high, net synchronization capability is good, service life is long, therefore extensive
Applied to fields such as automobile, metallurgy, space flight and aviation, boats and ships heavy industries, wherein universal coupling with spider is exactly a kind of typical
Spline pair type of attachment.
The flexible spline pair of existing universal coupling with spider, when splined shaft spends part set to be stretched to maximum position relatively
When, splined shaft is easily mutually disengaged with spline housing, and very big security risk is brought to production, time-consuming and laborious when ressembling, and
And influence production.
Utility model content
Above-mentioned in order to solve the problems, such as, the utility model proposes a kind of spline pair for preventing from surprisingly coming off, the flower
Key pair can prevent splined shaft from surprisingly coming off between each other with spline housing, ensured safety in production, improved work efficiency, and tie
Structure is simple, easy to operate.
To achieve these goals, the utility model uses following scheme, including：
Splined shaft, be sleeved on the spline housing being axially movable on splined shaft, and the left end of the splined shaft is circumferentially uniformly set
Some block pieces are put, the block piece is with spline positioned at same axial horizontal line；The left end of the spline housing is uniformly arranged in the circumferential direction
Some first tapped through holes, first tapped through hole and spline positioned at same axial horizontal line, first tapped through hole with
The block piece corresponds, and block piece can be adjusted by the first tapped through hole, first tapped through hole is screwed into outside first
Screw；The right end of the spline housing is uniformly arranged in the circumferential direction some second tapped through holes, second tapped through hole and the first spiral shell
Line through hole mirror symmetry, second tapped through hole are screwed into the second male screw thread.
The block piece is inner bolt, and the diameter of the inner bolt is slightly less than the diameter of the first tapped through hole, the inner bolt
It is threadedly coupled splined shaft.
The block piece is a block, and the block is embedded in groove, and the both ends of the block are equipped with adjusting screw, described
The middle part of block is equipped with trip bolt, and the adjusting screw, the diameter of trip bolt are slightly less than the diameter of the first tapped through hole.
The block piece, the first male screw thread, the second male screw thread are two or more.
In use, making the height of block piece be less than the height of spline, in order to which splined shaft stretches into spline housing, treat that splined shaft is stretched
After entering spline housing, block piece is directed at the first tapped through hole, the first tapped through hole on spline housing passed through using allen wrench,
Block piece is adjusted, block piece is slightly above the height of splined shaft spline, then screws on the first male screw thread, when disassembly is desired, is only needed
Splined shaft is pulled to low order end, at this moment the internal spline of spline housing blocks block piece, and the second male screw thread aligns with block piece, pulls down outside second
Screw can carry out block piece by the second tapped through hole moving down adjusting, so as to extract splined shaft out.
The utility model can prevent splined shaft from surprisingly coming off between each other with spline housing, ensure safety in production, improve
Work efficiency, and it is simple in structure, it is easy to operate.
Brief description of the drawings
Fig. 1 is the utility model section view schematic front view.
Fig. 2 is partial enlarged view when the utility model uses inner bolt.
Fig. 3 is partial enlarged view when the utility model uses block.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, Figure 2, Figure 3 shows, the utility model uses following scheme, including：
Splined shaft 1, be sleeved on the spline housing 2 being axially movable on splined shaft 1, and the left end of the splined shaft 1 is circumferentially equal
Even to set some block pieces, the block piece is with spline positioned at same axial horizontal line；The left end of the spline housing 2 is circumferentially uniform
Some first tapped through holes are set, and first tapped through hole leads to spline positioned at same axial horizontal line, first screw thread
Hole and the block piece correspond, and block piece can be adjusted by the first tapped through hole, and first tapped through hole is screwed into the
One male screw thread 3；The right end of the spline housing 2 is uniformly arranged in the circumferential direction some second tapped through holes, second tapped through hole with
First tapped through hole mirror symmetry, second tapped through hole are screwed into the second male screw thread 4.
The block piece is inner bolt 5, and the diameter of the inner bolt 5 is slightly less than the diameter of the first tapped through hole, the interior spiral shell
Nail 5 is threadedly coupled splined shaft 1.
The block piece is a block 6, and the block 6 is embedded in groove, and the both ends of the block 6 are equipped with adjusting screw
7, the middle part of the block 6 is equipped with trip bolt 8, and the adjusting screw 7, the diameter of trip bolt 8 are slightly less than the first screw thread and lead to
The diameter in hole.
