Abstract
The utility model belongs to automobile drive axle field, specifically a kind of tight lock construction of Novel reducer flange nut.The structure includes flange nut, bolt, O-ring and flange；The splined hole of the flange covers on the splined shaft of drive bevel gear；The O-ring is arranged on the groove between flange and drive bevel gear；The internal thread hole of flange nut is threadedly coupled with the external screw thread of drive bevel gear, and lower end surface and the end face of flange and O-ring fit；It is provided on the flange nut and bolted threaded hole.The utility model is a kind of simple tight lock construction of Novel reducer flange nut of structure, the structure promotes flange nut check reliability, reduce maintenance cost, it solves in existing drive axle, in use since the factors such as vibration, fatigue influence, and locking torque is lower, and collapsed position is caused to loosen, the problem of flange nut locking failure, reliability reduces.
Description
Technical field
The utility model belongs to automobile drive axle field, and specifically a kind of Novel reducer flange nut tightly locks knot
Structure.
Background technique
In domestic drive axle, the structure of drive bevel gear flange nut check is to mill gap in drive bevel gear end face, dash forward
The end face of edge nut is flattened, and the function of locking flange nut is realized in insertion milling gap position.Such structure, in use
Since the factors such as vibration, fatigue influence, and locking torque is lower, and collapsed position is easy to cause to loosen, and flange nut locking loses
The problem of effect, reliability reduces.Therefore after mostly using 100,000 kilometers of traveling, maintenance tightens that flange nut, locking is arranged again
It applies, increases maintenance cost.
Summary of the invention
The utility model provides a kind of simple tight lock construction of Novel reducer flange nut of structure, which is promoted prominent
Edge nut check reliability reduces maintenance cost, solves in existing drive axle, in use due to vibration, fatigue
Etc. factors influence, and locking torque is lower, and collapsed position is caused to loosen, and the failure of flange nut locking, what reliability reduced asks
Topic.
Technical solutions of the utility model are described with reference to the drawings as follows:
A kind of tight lock construction of Novel reducer flange nut, the structure include flange nut 1, bolt 2, O-ring 3 and flange
4；The splined hole of the flange 4 covers on the splined shaft of drive bevel gear 5；The setting of O-ring 3 is in flange 4 and actively
On groove between bevel gear 5；The internal thread hole of the flange nut 1 is threadedly coupled with the external screw thread of drive bevel gear 5, and
Lower end surface and the end face of flange 4 and O-ring 3 fit；The threaded hole connecting with bolt 2 is provided on the flange nut 1
6。
The tail portion of the splined shaft of the drive bevel gear 5 is using the multi-diameter shaft for installing O-ring 3.
The flange nut 1 uses radial groove structure, with the circle center line connecting perpendicular to threaded hole 6 and screwed hole of centre
Flange nut diameter be groove boundary, one end of groove is threaded hole 6, and the other end is through-hole.
The utility model has the following beneficial effects:
The flange nut of the utility model uses radially slotted structure, is slotted with bolt compresses, makes center screw thread and active
The screw-threaded coupling of bevel gear improves the reliability of locking；Relative to " drive bevel gear end face mills gap, the end of flange nut
Face flaser texture ", drive bevel gear reduce notching construction and optical axis gauge structure, reduce the axial dimension of drive bevel gear,
Mitigate weight, save the cost.

Fig. 3 is the structural schematic diagram of drive bevel gear.
In figure: 1, flange nut；2, bolt；3, O-ring；4, flange；5, drive bevel gear；6, threaded hole.
Specific embodiment
Refering to fig. 1, a kind of Novel reducer flange nut locking structure, including flange nut 1, bolt 2, O-ring 3 and prominent
Edge 4；The splined hole of flange 4 is packed into the splined shaft of drive bevel gear 5；O-ring 3 is packed into recessed between flange 4 and drive bevel gear 5
Slot；Flange nut 1 screws in the external screw thread of drive bevel gear 5, and tightens, and lower end surface is bonded with the end face of flange 4, and and O-ring
End face fitting；Bolt 2 screws in the threaded hole 6 of flange 4, and tightens, and keeps the both ends of the surface compression of fluting close.
Refering to Fig. 2 a, Fig. 2 b, the flange nut 1 uses screwed hole of centre, matches with the external screw thread of drive bevel gear 5
It closes；Using threaded hole 6, for connecting bolt 2；Using radial groove structure, with the circle perpendicular to threaded hole 6 and screwed hole of centre
The flange nut diameter of heart line is groove boundary, and one end of groove is threaded hole 6, and the other end is through-hole, when bolt 2 is tightened,
Two inner faces of groove are close, and the external screw thread of the internal screw thread and drive bevel gear 5 that make flange is locked；Using outer-hexagonal structure, use
In connection spanner.
Refering to Fig. 3, the tail portion of the splined shaft of the drive bevel gear uses multi-diameter shaft, for installing O-ring 3；Screw thread
Diameter uses full thread structure, cooperates with flange nut 1, without notching construction and optical axis gauge structure.
