Abstract
The utility model relates to a gear speed changing device. The existing gear speed changing device changes the rotation speed by changing different ratios of tooth number, and stepless speed change can not be realized. The utility model comprises a driving wheel, a driven wheel, a speed adjusting wheel, and a rotation speed adjusting device, wherein the driving wheel and the speed adjusting wheel are positioned in an axial line, and the axial line of the speed adjusting wheel is vertical to the axial line of the driving wheel. The driving wheel and the speed adjusting wheel are engaged mutually, and the speed adjusting wheel and the driven wheel are engaged mutually. The driven shaft is vertically connected with a dynamic force output shaft. Accordingly, the rotation speed of the dynamic force output shaft can be adjusted at will in the range from zero to half of the rotation speed of the dynamic force input shaft by the rotation speed adjusting device. Accordingly, the function of stepless speed change is realized.
Description
The utility model relates to a kind of speed change gear.
In the prior art, gear-shift transmission generally adopts shift to pull out wooden fork, and the method that changes different gear ratios changes rotating speed, but its complex structure, the rotating ratio regulation range is little, and can not realize stepless change.
The purpose of this utility model provides a kind of simple in structure, the stepless speed change gear that the rotating ratio regulation range is big.
For achieving the above object, the technical solution of the utility model is:
A kind of speed change gear, its special way is: described speed change gear comprises driving wheel 2, follower 4, flywheel 5 and speed setting unit 6; The intersect vertical axis of described driving wheel 2 and follower 4, and intermesh; The intersect vertical axis of follower 4 and flywheel 5, and intermesh; Between follower 4 and the driven shaft 3 bearing is set; At the intersect vertical axis place of flywheel 5 with follower 4, driven shaft 3 and 7 vertical connections of pto; Pto 7 is positioned on the same axis with power input shaft 2; Speed setting unit 6 is set on flywheel 5.
On the above-mentioned circumference that is positioned at driving wheel 2 and flywheel 5 2-4 follower 4 is set evenly, it intersects at circle center.
Speed setting unit 6 on the above-mentioned flywheel is a wearing piece.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Referring to accompanying drawing, its drawing reference numeral is described as follows:
The 1-power input shaft, the 2-driving wheel, the 3-driven shaft, the 4-follower, the 5-flywheel,
The 6-speed setting unit, the 7-pto.
The utility model is to be made of driving wheel 1, flywheel 5 and two followers 4 (also can adopt three or four followers) and speed setting unit 6, the dead in line of driving wheel 1 and flywheel 5, the intersect vertical axis of the axis of follower 4 and driving wheel 1, each gear intermeshes, thereby constitutes a kind of " mouth " type tower structure.Follower 4 can rotate on the circumference of driving wheel 2 and flywheel 5, and around driven shaft 4 rotations, because of driven shaft 3 and pto 7 in axes intersect place vertical be connected of follower with flywheel, make pto 7 have active input shaft 1 rotating speed between 0～1/2 scope by speed setting unit 6, arbitrarily rotating speed.Its power input shaft and pto by bearing fixing on support 8.
When wearing piece did not have any friction to flywheel, power input shaft drove driving wheel 1 and rotates, and under the load effect of the drive of driving wheel and pto, rotation only took place, and the rotating speed of pto is zero.And flywheel is under the drive of follower, and flywheel and driving wheel are oppositely with the speed rotation.
When wearing piece is stopped when tight fully to flywheel, flywheel does not rotate, under the effect of the drive of driving wheel and flywheel, and follower rotation on around the driving wheel, thereby make pto rotation under the driven rotary of driven shaft drives, its rotating speed is 1/2 of a driving wheel rotating speed.
According to above-mentioned two states, above-mentioned wearing piece is a wheel hub braking device wearing piece, by its control to the speed governing wheel speed, thereby the rotating speed that makes pto the power input shaft rotating speed 0～1/2 between regulate arbitrarily in the scope.
The friction that above-mentioned wearing piece produces also can be electromagnetic damping power, and its structure adopts the electromagnetic type structure.
The utility model is with respect to other speed change gear, and it is simple in structure, speed adjustable range the driving wheel rotating speed 0～1/2 between, and can realize stepless shift function.
