It is its shape as a tower, so being called " pagoda tooth ".
Bolt currently used for intermediate shaft locking is generally the model of M8 or M10, but M8 bolt under normal circumstances
Ultimate torque is only 50Nm or so, and the clamping force provided not enough locks intermediate joint fork, and alternating load is carried in durability experiment
Shi Rongyi failure.Increase annular knurl design in the lower section of the bolt the brim of a hat, cooperation corner tightens method, can be improved frictional force, provide foot
Enough clamping forces.
It needs a kind of raising frictional force, enhancing clamping force, band annular knurl under the bolt the brim of a hat of a certain amount of Flexible change can be born
Intermediate joint pitch fixed structure.
Utility model content
The purpose of the utility model is to provide a kind of raising frictional force, enhancing clamping force, a certain amount of Flexible change can be born
The bolt the brim of a hat under intermediate joint with annular knurl pitch fixed structure.
A kind of intermediate joint under the bolt the brim of a hat with annular knurl pitches fixed structure, comprising:
Intermediate joint fork, it is axocoel that the intermediate joint, which pitches one end, and the other end is section entry, and the axocoel is matched with gear shaft
It closes, setting section plug on the section entry, the axial direction of the axocoel, axocoel side is arranged axocoel and stitches, and is arranged radially locking hole, institute
It states locking hole and bolt cooperates, axocoel locking, the bolt column and locking hole of the bolt is threadedly engaged, the bolt head of the bolt
With the lower deep gouge cooperation of intermediate joint fork, annular knurl is arranged in the bolt head and lower deep gouge contact position.
The axocoel is circle, is equipped with serrated slot.
The locking hole is divided into two up and down by axocoel seam, is respectively equipped with internal screw thread.
The quantity of the section plug is two, is oppositely arranged.
The bolt head is interior hexagonal.
The annular knurl is arranged radially along bolt column, is diverging shape, is uniformly arranged on bolt head bottom surrounding.
It is axocoel that joint, which pitches one end, among the utility model, and the other end is section entry, and axocoel and gear shaft cooperate, and saves entry
Upper setting saves plug, the axial direction of axocoel, and axocoel side is arranged axocoel and stitches, and is arranged radially locking hole, and locking hole and bolt cooperate, axis
Chamber locking, the bolt column and locking hole of bolt are threadedly engaged, the lower deep gouge cooperation of the bolt head of bolt and intermediate joint fork, bolt
Annular knurl is arranged in head and lower deep gouge contact position.The utility model improves frictional force, enhancing clamping force, can bear a certain amount of elasticity change
Change.
Detailed description of the invention
Fig. 1 is the exploded perspective figure of the utility model;
Fig. 2 is the cross-sectional view of the utility model;
Fig. 3 is the perspective view of the utility model bolt.
In figure: 1, intermediate joint fork, 2, bolt, 3, gear shaft, 11, axocoel, 12, axocoel seam, 13, locking hole, 14, sinking
Slot, 15, section entry, 16, section plug, 21, bolt column, 22, bolt head, 23, annular knurl.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Referring to Fig. 1 to Fig. 3, the intermediate joint under a kind of bolt the brim of a hat with annular knurl pitches fixed structure, comprising: intermediate joint fork
1, it is axocoel 11 that intermediate joint, which pitches 1 one end, and the other end is section entry 15, and axocoel 11 and gear shaft 3 cooperate, save and set on entry 15
Section plug 16, the axial direction of axocoel 11 are set, 11 side of axocoel is arranged axocoel and stitches 12, is arranged radially locking hole 13, locking hole 13 and spiral shell
Bolt 2 cooperates, and axocoel 11 is locked, and the bolt column 21 and locking hole 13 of bolt 2 are threadedly engaged, the bolt head 22 and jackshaft of bolt 2
The lower deep gouge 14 of section fork 1 cooperates, and annular knurl 23 is arranged in bolt head 22 and lower 14 contact position of deep gouge.
Axocoel 11 is circle, is equipped with serrated slot.Locking hole 13 is divided into two up and down by axocoel seam 12, is respectively equipped with interior spiral shell
Line.The quantity for saving plug 16 is two, is oppositely arranged.Bolt head 22 is interior hexagonal.Annular knurl 23 is set along the radial direction of bolt column 21
It sets, is diverging shape, is uniformly arranged on 22 bottom surrounding of bolt head.
Increase the design of annular knurl in bolt the brim of a hat bottom, is that bolt generates more frictional force in application process, provides
