Abstract
The utility model discloses a gear with adjustable meshing side clearance, comprising a main gear (1) and a rotation displacement compensation auxiliary gear (2); the main gear is coaxially connected and mounted with the rotation displacement compensation auxiliary gear; the gear parameter of the rotation displacement compensation auxiliary gear is the same with the gear parameter of the main gear; the rotation displacement compensation auxiliary gear is mounted and staggered with a certain angle relative to the main gear. The tooth thickness of the gear set is increased due to the main gear and the rotation displacement compensation auxiliary gear which are mounted with the staggered angle; the meshing clearance is eliminated when the gear set is meshed with other gears.
Description
Technical field
The utility model relates to the structure of can regulate gear engagement sideshake, and particularly a kind of encoder that is applied to seamless electronic jacquard knitting machine-Hough dish and syringe is gathered the gear of gear transmission signal.
Background technique
In seamless electronic jacquard knitting machine knitting technology, need to detect the synchronous rotary state of syringe and Hough dish, most common way adopts encoder to gather the gear transmission aspect, promptly on encoder, add a gear and tested gear engagement, with the mode that increases velocity ratio,, improve the precision of the rotational displacement that records main shaft through certain magnification factor, detect the rotational velocity of tested gear, realize closed loop control.Common encoder is gathered gear transmission aspect (with reference to Fig. 5), is rotated by tested gear driven encoder gear, extracts the swing offset amount that tested gear rotates.Yet,, make the measured value of its spot speed still exist certain deviation because influence and the assembly error and the precision deficiency of gear own of the foozle in gear, spindle hole and encoder hole have caused the existence of gear engagement sideshake 9.
Along with the progress of seamless electronic jacquard knitting machine knitting technology, to detecting the lasting accuracy that syringe rotates, the rotational synchronization state of accurately measuring syringe and Hough dish has proposed new requirement.
In sum, the transmission because the direct geared of mainshaft gear drive encoder is meshing with each other, produce the problem of shock impacts easily by the between cog sideshake, so can in transmission process, produce noise, seriously influenced the extraction precision of turn signal, make moment output signal and the rotating speed of actual main shaft differ an angle, this will influence finishing of seamless electronic jacquard knitting machine knitting technology weave.
Summary of the invention
The purpose of this utility model is to propose a kind of gear train that can adjust meshing backlass, be applied to the signals collecting of the encoder gear of seamless electronic jacquard knitting machine, in order to eliminating the sideshake of gear engagement, to alleviate the influence of the destabilizing factor that vibrations and noise brought.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of gear train of can regulate meshing backlass, it comprises a master gear and a swing offset compensation pinion, master gear and the coaxial installation that links to each other of swing offset compensation pinion, the gear parameter of described swing offset compensation pinion is identical with master gear, and the master gear several angle installation of staggering relatively.
Swing offset compensation pinion is done centralized positioning with being connected by a hollow locating stud of master gear, has the attachment screw hole on the swing offset compensation pinion, the aperture in attachment screw hole is greater than the diameter of attachment screw, and attachment screw passes the attachment screw hole and swing offset is compensated pinion is fastened on the master gear.
Also be provided with Cock screw on the swing offset compensation pinion, this Cock screw passes swing offset compensation pinion and contacts with the end face of master gear.
The beneficial effects of the utility model are, the master gear of the angle that staggers and swing offset compensation pinion make the transverse tooth thickness of this gear train increase, and when it and tested gear engagement, can eliminate the sideshake of engagement; Again since the aperture in attachment screw hole greater than the diameter of attachment screw, so swing offset compensation pinion can rotate a little, also just can adjust transverse tooth thickness according to the state of reality engagement, thus the adjusting meshing backlass; Adopt the scheme of Cock screw, can utilize attachment screw tentatively to adjust transverse tooth thickness, tighten Cock screw then, guarantee the size of transverse tooth thickness exactly, avoid the transverse tooth thickness of adjusting being changed once more owing to tightening attachment screw.

Embodiment
Shown in Fig. 1～3, the gear of the utility model can regulate meshing backlass comprises a master gear 1 and a swing offset compensation pinion 2, master gear 1 and the 2 coaxial installations that link to each other of swing offset compensation pinion, the gear parameter (Base radius, Pitch radius, dedendum of the tooth, addendum, tooth pitch, modulus) of swing offset compensation pinion 2 is identical with master gear 1, and relative master gear 1 several angle that staggers.Has kingpin hole 3 on the swing offset compensation pinion 2, attachment screw hole 4 and set screw hole 5, swing offset compensation pinion 2 is to do centralized positioning by a hollow locating stud 6 with being connected of master gear 1, and it is fastening by attachment screw 7 and Cock screw 8, Cock screw 8 is screwed in the set screw hole 5 of swing offset compensation pinion 2 and passes swing offset compensation pinion 2 and contacts with the end face of master gear 1, tighten attachment screw 7 and swing offset can be compensated pinion 2 and draw close mutually, tighten Cock screw 8 and swing offset can be compensated pinion 2 and be separated with master gear 1 with master gear 1.Use attachment screw 7 and Cock screw 8 can accurately regulate the angle that staggers of swing offset compensation pinion 2 relative master gears 1 simultaneously.
Attachment screw and Cock screw can adopt socket head screw.
During assembling, earlier swing offset is compensated pinion 2 by hollow locating stud 6, be contained on the master gear 1, and swing offset compensated angle of pinion 2 rotation, with the transverse tooth thickness slide calliper rule measure survey transverse tooth thickness than standard transverse tooth thickness big about 8% after, suitably tighten attachment screw 7, in the structure with its engagement of packing into, adapt to engagement after, again the gear of can regulate meshing backlass is pulled down, twist firm Cock screw 8, swing offset can be compensated pinion 2 and be fixed into one with master gear 1.
Shown in Fig. 4,5, when two ordinary gears are meshing with each other,, make the measured value of its spot speed still exist certain deviation because influence and the assembly error and the precision deficiency of gear own of foozle have caused the existence of gear engagement sideshake 9.
As shown in Figure 6, adopt the gear of the utility model can regulate meshing backlass, eliminated gear meshing sideshake 9.
