Abstract
The invention relates to a transmission mechanism of a detaching roller on a combing machine which is provided with a non-circular planetary gear train. The mechanism comprises two sun gears, a tie bar and an even number of planetary gears. The transmission mechanism outputs variable motions including natural rotation, stop and reversion in every working circle (which means the 360 degree rotation of a cylinder), drives the detaching roller to change the speed and the direction of the rotation in accordance with the requirements of the process when the tie bar is rotating at the constant speed driven by a single power source by constructing a pitch curve of the non-circular gear.
Description
Technical field
The present invention relates to the transmission mechanism of combing machine detaching roller, especially the non-circular planetary gear train transmission mechanism of combing machine detaching roller.
Background technology
For combing machine detaching roller can be moved by technological requirement, reach the effective length of delivery (total clockwise amount is poor with total reversing amount) of expection, the transmission of existing combing machine detaching roller adopts following two kinds of patterns to realize; 1) combination of planar linkage mechanism and differential cyclic train realizes; 2) by conjugate cam, the combination of one group of four connecting rod and differential cyclic train realizes.Owing to be to synthesize the iso-variable velocity that realizes just changeing, stops, reverses, break-in campaign by the motion of box of tricks.Therefore, the number of components is more, the designing and calculating difficulty is big, kinematic accuracy is low, cost increases.
Summary of the invention
The objective of the invention is for the drive control precision that improves combing machine detaching roller, simplify the internal structure of an organization, reduce cost.
The technical scheme that the present invention solves its technical problem employing is: adopt non-circular planetary gear train, by making up the pitch curve of non-circular gear, realize just changeing, stop, reversing.
Beneficial effect
The invention has the advantages that simple in structurely, reliable, reduce by 50% parts than existing mechanism approximately.Minimumly utilize four gears just can be implemented in the working cycles to realize just changeing, stop, reverse iso-variable velocity, break-in campaign once.For the drive control precision, the operating rate that improve combing machine detaching roller with separate bond quality, important meaning is arranged.
Below in conjunction with drawings and Examples, the present invention is carried out detailed presentations

Non-circular planetary gear train mechanism (14) contains sun gear (1), planetary gear (2), planetary gear (3), sun gear (4), tie-rod (H), axle (D1), axle (D1).Gear (6), gear (7), gear (8), gear (10), gear (11), gear (12), axle (9), belt pulley (5), detaching roller (13).
Specific embodiments
As shown in Figure 1, through gear (6), gear (7) drives cylinder axis (9) by belt pulley (5).Gear (8) the drive tie-rod (H) that is fixed on the cylinder axis (9) is done uniform rotation around axle (D1).When planetary gear (2), planetary gear (3) are done at the uniform velocity revolution with tie-rod (H) around axle (D1), do rotation around axle (D2) axis again.
Sun gear (1) is fixed on the frame (not drawing) and does not rotate, and planetary gear (2), planetary gear (3) are rigidly connected with axle (D2).The spin velocity of planetary gear (2), planetary gear (3) is identical, and constantly changes, and does speed change, break-in revolution thereby drive sun gear (4).And then gear (11) driven gear (10) by being connected with sun gear (4), (12) rotate speed change, break-in and pass to detaching roller (13).
Figure 3 shows that transmission ratio curve, Figure 4 shows that the angle relation curve, Figure 5 shows that the angular acceleration curve.Independent variable among these figure (abscissa) is the corner of tie-rod (H), and it and cylinder axis (9) corner are linear relationships.This shows,, under the single movement input, can realize simply, accurately that detaching roller (13) satisfies the motion of technological requirement by making up the pitch curve of non-circular gear.
