Specific embodiment
The embodiment provided with reference to the accompanying drawing is described in detail the utility model:
Only for convenience, in the following description, used specific direction term, for example, "upper", "lower",
"left", "right" etc. is limitations of the present invention can not to be considered, when drawing using corresponding attached drawing as reference
When definition direction changes, the direction that these words indicate should be construed as corresponding different directions.
Referring to Fig. 1-Fig. 6, it is a kind of can dynamic adjustment gear meshing backlass gear set, including driven gear 1 and adjusting tooth
Wheel 2；The teeth portion parameter of the adjustment gear 2 remaining parameter in addition to modification coefficient is identical as the teeth portion parameter of driven gear 1；It is described
Adjustment gear 2 and driven gear 1 are coaxially disposed, and the certain angle installation that is staggered.
The end face of the driven gear 1 is equipped with the mounting groove 4 of annular, is uniformly distributed three mounting holes 9 in mounting groove 4,
One pin 3 is installed, for pin 3 perpendicular to the end face of driven gear 1, pin 3 and mounting hole 9 use interference in each mounting hole 9
Cooperation.
Adjustment gear 2, which is equipped with, passes through adjustment hole 5 with the one-to-one adjustment hole 5 of pin 3, pin 3, and adjustment hole 5 is length
Arc-shaped hole, the both ends of long arc-shaped hole are arc surface 12, and the diameter of arc surface 12 is greater than the diameter of pin 3；In adjustment gear 2
Retaining wall 6, the end face that retaining wall 6 is located at adjustment gear 2 and driven gear 1 is bonded, the quantity of retaining wall 6 are nearby equipped with positioned at adjustment hole 5
Identical as the quantity of adjustment hole 5, the retaining wall 6 in adjustment gear 2 is using stamping.Compressed spring 7 is equipped in mounting groove 4, often
