In example, the number of teeth taking the first bevel gear 51 is 46, and the number of teeth of the second bevel gear 52 is 50, third hand tap
The number of teeth of gear 53 is 47, and the number of teeth of the 4th bevel gear 54 is 47, i.e. M is 46, and N is 4, then
The ratio of power shaft 20 and output shaft 60 rotating speed that described cone tooth swings bidentate difference speed change gear is:
As it is shown in figure 1, when described power shaft 20 is driven by motor (not shown) and rotates,
Power shaft 20 drives the first bevel gear 51 and the second bevel gear by oblique deflection wheel 30 and the second bearing 42
52 roll the meeting while revolving round the sun of engagement, the first bevel gear 51 and third hand tap gear 53 with power shaft 20
Rotation is produced around the center of the second bearing 42.Meanwhile, described third hand tap gear 53 is by boring with the 4th
The rolling engagement of gear 54 drives the 4th bevel gear 54 to rotate, and is driven output by the 4th bevel gear 54
Axle 60 rotates, and the transmission after speed change is exported.
Taking this, this utility model swings bidentate difference structure by cone tooth and achieves the big speed change of single-stage speed change
Compare speed change so that the volume of speed change gear, weight significantly reduce, and transmission efficiency is substantially improved.
Although this utility model being disclosed by above example, but protection of the present utility model
Scope is not limited thereto, under conditions of conceiving without departing from this utility model, to above each component institute
The deformation done, replacement etc. all will fall in right of the present utility model.
