Abstract
The utility model discloses a highly-centered coupling, which comprises a shaft rod with a shaft hole, wherein the inner wall of the shaft hole is provided with a key groove in the axis direction, the cross section of the key groove is in a cone shape, the outer wall of the shaft rod is provided with an annular flange, the end surface of the flange is flush with the end surface of the shaft rod, the flange is provided with a pin shafts which is are annularly distributed, the front end of the each pin shaft is provided with a thread connecting section, and the inner side of the pin hole is provided with an annular positioning groove. The highly-centered coupling has the advantages that the structure design is novel; by adopting the conical key groove, the pin shafts, the positioning groove and the like, the to-be-coupled shafts and the matched coupling are mutually connected, so the centering and the stability between the two coupled shafts are ensured, and the service life of the equipment is also prolonged.
Description
technical field:
The utility model relates to coupling manufacturing technology, relates in particular to a kind of high centering coupling.
background technique:
Coupling is mainly used in the connection between diaxon, and it also can be used for the connection between axle and reel, gear, belt wheel etc., and the main task of coupling is transmitting torque.
For being connected between axle and axle, all there is certain defect in most of coupling, although can be connected firmly, the centering between two axles after connecting is relatively poor, such as connection between high speed shaft, if centering is poor, affect the working life of equipment.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of high centering coupling, and reasonable in design can guarantee two stability and centerings after the connection between coupling shaft.
The technical solution of the utility model is as follows:
High centering coupling, comprise the axostylus axostyle with axis hole, it is characterized in that: the inwall of described axis hole is provided with along axial direction the keyway that cross section is taper, the outer wall of described axostylus axostyle is provided with annular flange, the end face of flange is concordant with the end face of axostylus axostyle, flange is provided with the bearing pin that prolongs annular spread, and the front end of bearing pin is provided with the section of being threaded, and pin-and-hole inner side is provided with annular locating slot.
Described high centering coupling, is characterized in that: described bearing pin is conical column.
Described high centering coupling, is characterized in that: the width of described locating slot reduces gradually from notch to bottom.
The utility model has the advantages that:
The utility model structural design novelty, the structures such as keyway by taper, bearing pin, locating slot, and between the coupling coordinating with it on the axle that needs connect, be coupled to each other, can guarantee to connect centering and the stability between rear two axles, also extended the working life of equipment.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
High centering coupling, comprise the axostylus axostyle 1 with axis hole 2, the inwall of axis hole 2 is provided with along axial direction the keyway 3 that cross section is taper, the outer wall of axostylus axostyle 1 is provided with annular flange 4, the end face of flange 4 is concordant with the end face of axostylus axostyle 1, flange 4 is provided with the bearing pin 5 that prolongs annular spread, and the front end of bearing pin 5 is provided with the section of being threaded 6, and pin-and-hole 2 inner sides are provided with annular locating slot 7.
Bearing pin 5 is conical column, and not only in connection procedure, stability and soundness improve, and have certain damping effect, meet user demand.
The width of locating slot 7 reduces gradually from notch to bottom, cooperatively interacts with the coupling of installing on other coupling shafts, and location rear stability is good, and the centering between two axles is guaranteed.
