Explanation.
In the present embodiment, fluted disc tooth 31 is full-height tooth, and No. ten tooth, that is, centre tooth 421 in sliding block tooth 42 is standard
Tooth, the sliding block tooth 42 of remaining 40 both sides of sliding block center line is deformation tooth." full-height tooth " mentioned here refers to：Fluted disc initial design
The tooth form of sizing, tooth form angular dimension are determined according to factors such as fluted disc diameter, the high size of required tooth, the quantity of circumferential teeth.It should
Fluted disc tooth form angle is generally set in 65 ° -75 °, due to it for the prior art i.e. it be well-known to those skilled in the art, therefore
No longer specifically describe.Described " deformation tooth " refers to：When once fluted disc determines the tooth form of full-height tooth, such as fluted disc profile angle
Degree is set as 70 °, then for fluted disc because the tooth of whole circumference is completely the same, the tooth form angle of fluted disc slot is also all 70 °；And
The tooth of sliding block center line both sides suitably makees tooth form angle some finishing deformations to promote the performance locked.
In the present embodiment, sliding block tooth form angle is α, and fluted disc slot tooth form angle is β, wherein：Its center tooth 421 is mark
Quasi- tooth, sliding block tooth form angle are deformation tooth tooth form angle for α 10, remaining α 1- α 9 and α 11- α 19.
Sliding block tooth 42 modify principle be allow 40 both sides of sliding block center line tooth crown（Such as crown 422）Toward sliding block center line 40
Direction deviates a distance, and ensures that interference cannot be generated with fluted disc slot 32 during engagement；Method is to ensure that each tooth form close to sliding
The serrated edge of line side is constant in block, and the serrated edge away from line side in sliding block turns an angle and deviates an angle, final to increase
The method of big sliding block tooth form angle is realized, and the tooth more remote from sliding block center line 40 needs increased angle bigger.Therefore,
The deformation tooth on described left and right both sides is as away from sliding block center line 40 i.e. centre tooth 421, each pair, which deforms the increased angle of tooth, is
The process of one reflected gradient.
It should be noted that as needed each pair deformation tooth increase angle amplitude be not necessarily it is constant, according to crown
The size of offset is needed to determine, it is certainly, constant also possible.Therefore, tooth is not interfered with to the variation for deforming tooth at this time
The diameter of disk 3 namely the diameter of fluted disc 3 will not change because of the variation of deformation tooth；Once the tooth form angle-determining of full-height tooth
Afterwards, fluted disc diameter is unrelated with deformation tooth.

Sliding block tooth 42 is on the basis of centre tooth 421, and deformation tooth 43 its all right edge 430 in the left side are i.e. close to line side in sliding block
Serrated edge it is constant, left side deformation tooth 43 its all left side are gradually pulled open on the basis of centre tooth 421 to its left side to be made
Tooth form angle [alpha] gradually increases, i.e., the serrated edge away from line side in sliding block turns over an angle；And the right its all left side of deformation tooth 44
Side 440 is that the serrated edge of line side in close sliding block is constant, and the right its all right edge of deformation tooth 44 are base with centre tooth 421
Standard is gradually pulled open to its right edge makes tooth form angle [alpha] gradually increase, so that sliding block tooth 42 is made to be nibbled into corresponding fluted disc slot 32
It closes.In the present embodiment, deformation its left side 439-431 of tooth 43 in the left side is gradually drawn on the basis of centre tooth 421 to its left side
Opening makes gradually 1 ° -9 ° of the increases of tooth form angle [alpha] 9- α 1；The right deform its right edge 441-449 of tooth 44 on the basis of centre tooth 421 to
Its right edge, which is gradually pulled open, makes gradually 1 ° -9 ° of the increases of tooth form angle [alpha] 11- α 19.In this way, sliding block 4 will not block with fluted disc 3 during use
Firmly, they can all be engaged in any position of work to same direction." being engaged to same direction " mentioned here refers to：If with
The left side is front, each sliding block tooth 42 is engaged to the fluted disc slot 32 of the front.
In addition, if left side deformation tooth 43 and the right deformation tooth 44 its tooth form angle are not naturally also can by steady state value increase
With.For example, the tooth form angle [alpha] 10 of centre tooth 421 is 70 °, 12=71 ° of 11=70.5 ° of 9=α of α, 8=α of α, 13=72 ° of 7=α of α, 6=α of α
14=73 °, 16=76 ° of 15=74 ° of 5=α of α, 4=α of α, 18=78.5 ° of 17=77 ° of 3=α of α, 2=α of α, 19=81 ° of 1=α of α.
