The conjugate cam transmission device of combing machine detaching roller
One, technical field:
The utility model belongs to a kind of transmission mechanism of combing machine detaching roller, is specifically related to a kind of conjugate cam transmission device of combing machine detaching roller.
Two, background technology:
At present, the kind of drive of the detaching roller of high-effect combing machine has two kinds: first kind is the mode that planar linkage mechanism combines with differential gear train, second kind is conjugate cam, the mode that linkage combines with differential gear train, see that from the effect that reality is used this dual mode can both satisfy the technological requirement that web separates combination, but they all have defective separately again, adopt first kind of mode, the number of connecting rod is more, the processing dimension error of each connecting rod can make the accumulated error of entire mechanism strengthen, thereby influence the kinematic accuracy of detaching roller, adopt the second way, structure is still complicated, and the geared head size strengthens.
Three, summary of the invention:
The utility model provides a kind of conjugate cam to combine the transmission mechanism of transmission combing machine detaching roller with differential gear train at existing problem in present combing machine detaching roller transmission mechanism and the technology.
The technical solution adopted in the utility model is: a kind of conjugate cam transmission device of combing machine detaching roller, it comprises casing 1, supporting seat 2, screw 3, pin 4, sliding bearing 5, screw 6, conjugate cam 7, roller 8, little axle 9, swing arm 10, screw 11, flange 12, gear 13, cylinder axis 14, differential gear train tie-rod 15, differential gear train planet carrier 16, screw 17, screw 18, supporting seat 2 is fixed on the casing 1 by screw 3, sliding bearing 5 usefulness pins 4 and screw 6 are fixed on the supporting seat 2, cylinder axis 14 and flange 12 interference fit joint, flange 12 is connected on the gear 13 by screw 18, conjugate cam 7 is placed on the cylinder axis 14, and be connected on the gear 13 by screw 17, conjugate cam 7 is arranged on the sliding bearing 5, roller 8 is installed in the swing arm 10 by little axle 9, two cams of two rollers 8 and conjugate cam 7 contact, swing arm 10 is fixed on the differential gear train tie-rod 15 with screw 11 with the Hough form, gear on the cylinder axis 14 and 16 engagements of differential gear train planet carrier.The eccentric throw in the axle center of differential gear train tie-rod 15 and swing arm 10 axle center is the 0.3-1 millimeter.Be carved with scale on the circumference of conjugate cam 7 ring flanges.
The utility model compared with prior art has following beneficial effect: simple in structure, accumulated error is little, installs easy to adjust.
