Abstract
The invention discloses a straight tooth and end tooth connecting structure of a three-jaw connecting-rod disk of a high-speed locomotive, which the shaft end circumferences at the corresponding positions of three force transferring jaws on a six connecting rod disk are equidistantly divided at an angle of 120 degrees; three groups of straight tooth groups are uniformly arranged on the shaft end circumference; and bolt holes are respectively formed on three plane regions on the shaft end circumferences of the three groups of straight tooth groups. A driving hollow shaft end is also equidistantly divided at an angle of 120 degrees; another three groups of straight tooth groups are uniformly arranged on the driving hollow shaft end and correspond to the driving hollow shaft end on the six connecting rod disk; and bolt holes matched with the bolt holes on the six connecting rod disk are also arranged on the circumference of the driving hollow shaft. The straight tooth and end tooth connecting structure has a compact structure; by combining the characteristic of a three-jaw structure of the traditional six connecting rod disk, the space positions of the end teeth and pre-tightening bolt holes are reasonably distributed and the damage to the shape of the end teeth is avoided, thereby effectively improving the stressed state of the end teeth and improving the connecting reliability of the end teeth. The invention has the advantages that the straight tooth and end tooth connecting structure has favorable self-aligning function and is convenient to manufacture, assemble and disassemble; and the larger torsion can be effectively transmitted.
Description
Technical field
Patent of the present invention belongs to railway locomotive, especially high-speed locomotive steering frame manufacturing technology field.
Background technology
The high speed railway engine truck adopts wheel that hollow shaft is added two six connecting bar disk type of drive, with the frame mode of realizing that drive rack is outstanding.For the actuating device of speed 200km/h high power AC transmission, its drive torque needs to connect by end tooth, and the moment of driven gear is passed to drive sleeve by end tooth.Two end tooth faces apply axial pre tightening force by pretension bolt, rely on the profile of tooth carry-over moment of annulus end face; This structure connection mode, but its compact conformation transfer larger torque, easy assembly and disassembly.It is the right-angled crossing formula that the end tooth of six connecting bar disks that existing express locomotive is used is often arranged, this kind end tooth is arranged and is easy to make, but because three power transmission pawls of six connecting bar disks are by 120 degree five equilibriums, a plurality of end tooth profiles of tooth will be destroyed in its axial pretightening bolt group hole, the stress concentration phenomenon may appear in the intersection place of passing through mutually at the bolt hole and the flank of tooth, reduce the intensity of end tooth.
Summary of the invention
In view of the above shortcoming of prior art, the purpose of this invention is to provide a kind of three-jaw connecting bar disk linear end tooth connecting device of proposition, make it the locus of reasonable distribution end tooth and bolt hole, the centering performance is good, avoids profile of tooth to destroy, and improves the force-bearing situation of end tooth.
The objective of the invention is to realize by following means.
High-speed locomotive steering frame three-jaw connecting bar disk straight-tooth end tooth connecting structure, adopt and take turns the type of drive that hollow shaft is added two six connecting bar disks, apply the axial pretightening locking by pretension bolt behind the end tooth tabling of the end tooth of six connecting bar disks and drive sleeve and constitute power chain.Evenly arrange three groups of straight-tooth groups by 120 degree five equilibriums on the axle head circumference of three power transmission pawl position correspondence positions on six connecting bar disks, three plane areas on its axle head circumference are arranged bolt hole respectively; Correspondingly, the end tooth of the end tooth of drive sleeve also arranges evenly that by 120 degree five equilibriums three groups of straight-tooth groups are corresponding with three groups of straight-tooth groups on six connecting bar disks, and its end circumference also is provided with the bolt hole that matches with six connecting bar disk upper bolt holes.
Adopt structure as above, compact conformation of the present invention is in conjunction with three power transmission pawl constructional features of existing six connecting bar disks, the locus in reasonable distribution end tooth and pretension bolt hole, avoid the end tooth profile of tooth to destroy, thereby improved the end tooth strained condition effectively, improved end tooth bonded assembly reliability.The present invention also has good in the centering effect, can transmit bigger moment effectively, conveniently make, is convenient to the advantage of assembly and disassembly.
Description of drawings
Fig. 1 high-speed locomotive steering frame three-jaw connecting bar disk straight-tooth end tooth connecting structure cutaway view.
Fig. 2 is the birds-eye view of the present invention six connecting bar disk end tooth portions.
The specific embodiment
Below in conjunction with drawings and Examples structure of the present invention is described further.
Among the figure, 1-drive sleeve, 2-drive sleeve end tooth group, 3-six connecting bar disks, 4-pretension bolt, 5-six connecting bar disk power transmission pawls, 6-six connecting bar disk end teeth, 7-end tooth plane area, 8-pretension bolt hole.
Each position component relation of the present invention be can see in conjunction with Fig. 1 and Fig. 2, by 120 degree five equilibriums, three groups of end tooth groups 6 and three plane areas 7 evenly arranged on the axle head circumference of six connecting bar disks 3.Three protruding pawls of three groups of end teeth 6 and six connecting bar disks, 5 positions are corresponding, arrange 3～4 bolts hole 8 on the plane area 7.The end of drive sleeve 1 also is provided with the end tooth group 2 with end tooth group 6 tablings.The end tooth of drive sleeve 1 and six connecting bar disks 3 is with axis location and chimeric mutually; Realize that with pretension bolt 4 axial pretightening end teeth two parts are rigidly connected.
Claims (2)
