Technical field
The utility model belongs to Rapier looms, is specifically related to wefting insertion in a kind of Rapier looms, connects the adjusting device of latitude gear-box gear drive centre-to-centre spacing.
Background technology
At present, the reciprocating motion of sword belt in the Rapier looms relies on wefting insertion, connects gear in the latitude gear-box and carry out periodic forward and reverse engagement and realize.Usually the structure that adopts circumferentially uniform three double crosslinking gear shafts and central gear to mesh simultaneously in casing guarantees accurate forward and reverse transmission between gear.This structure is higher to the requirement on machining accuracy of gear and gear housing, mechanism's relative complex, in process of production often because wefting insertion, the circumferentially equal portion hole that connects installation double crosslinking gear shaft on the latitude gear-box and the form and position tolerance between the centre bore are overproof, and gear common normal average length and deviation are overproof, and influence the motion of sword belt in the installation of gear and the weaving process.
Summary of the invention
Technical problem to be solved in the utility model is in order to overcome existing mechanism processing and manufacturing cost height, big, the baroque deficiency of manufacture difficulty, original structure is improved, and wefting insertion in a kind of Rapier looms is provided, connects the adjusting device of latitude gear-box gear drive centre-to-centre spacing.Structure after the improvement has not only reduced manufacturing cost, processing and manufacturing difficulty, and can the transmission centre-to-centre spacing to gear regulate among a small circle, thereby guarantees the accurate transmission and the engagement of gear.
The technical solution of the utility model: wefting insertion, connect in the latitude gear-box 2 circumferentially uniform, change one into three double crosslinking gear shafts of change speed pinion axle 1 engagement; At wefting insertion, connect latitude gear-box (2) and go up the installing hole place of double crosslinking gear shaft 6 and increase bearing block bottom outlet and several bearing block installing hole; At wefting insertion, connect and be provided with double crosslinking gear shaft 6 in the latitude gear-box 2, speed change gear wheel 4, change gear shaft 1, bearing block 3, a pair of angular contact radial ball bearing 7, eccentric adjusting sleeve 5, at each wefting insertion, connect and be provided with a double crosslinking gear shaft 6 in the latitude gear-box, a speed change gear wheel 4, a change gear shaft 1, wherein the axle head of doubly-linked gear shaft 86 is provided with a pair of angular contact radial ball bearing 7 and bearing block 3, bearing block 3 is by bolt 8 and wefting insertion, connecing latitude gear-box 2 connects, have at least a connecting hole that rotatable eccentric adjusting sleeve 5 is housed in the bearing block bottom outlet of bearing block and casing, the eccentric throw of eccentric adjusting sleeve 5 is 1～2mm.Between the bearing block bottom outlet of bearing block and casing adjustable slight clearance is arranged, the gap is 0.2-0.5mm.It is 05-0.8mm that adjustable slight clearance gap is arranged between the unthreaded hole of wearing bolt on bolt and the casing.
The beneficial effects of the utility model: simplify Rapier looms wefting insertion, connect the structure of latitude gearbox parts, reduce the processing and manufacturing cost, and can reach the requirement of adjusting gear transmission centre-to-centre spacing, to guarantee the accurate forward and reverse cycle transmission between gear.

The specific embodiment
Further specify by embodiment below in conjunction with accompanying drawing.
Wefting insertion, connect in the latitude gear-box 2 circumferentially uniform, change one into three double crosslinking gear shafts of change speed pinion axle 1 engagement; At wefting insertion, connect latitude gear-box (2) and go up the installing hole place of double crosslinking gear shaft 6 and increase bearing block bottom outlet and several bearing block installing hole; At wefting insertion, connect and be provided with double crosslinking gear shaft 6 in the latitude gear-box 2, speed change gear wheel 4, change gear shaft 1, bearing block 3, a pair of angular contact radial ball bearing 7, eccentric adjusting sleeve 5, at each wefting insertion, connect and be provided with a double crosslinking gear shaft 6 in the latitude gear-box, a speed change gear wheel 4, a change gear shaft 1, wherein the axle head of doubly-linked gear shaft 86 is provided with a pair of angular contact radial ball bearing 7 and bearing block 3, bearing block 3 is by bolt 8 and wefting insertion, connecing latitude gear-box 2 connects, have at least a connecting hole that rotatable eccentric adjusting sleeve 5 is housed in the bearing block bottom outlet of bearing block and casing, the eccentric throw of eccentric adjusting sleeve 5 is 1.5mm.Between the bearing block bottom outlet of bearing block and casing adjustable slight clearance is arranged, the gap is 0.3mm.It is 06mm that adjustable slight clearance gap is arranged between the unthreaded hole of wearing bolt on bolt and the casing.
Spoon wefting insertion, the kind of drive that connects the latitude gearbox parts are: speed change gear wheel 4 drives double crosslinking gear shafts 6 rotations, and double crosslinking gear shaft 6 drives 1 rotation of change speed pinion axles.In Fig. 1, after 3 assemblings of double crosslinking gear shaft 6, a pair of angular contact radial ball bearing 7, bearing block, by bolt 8 with this assembly with wefting insertion, connect latitude gear housing 2 and be connected.During connection at wefting insertion, connect the bolt 8 of packing in the bearing block installing hole on the latitude gear housing 2, in the installing hole (A place among Fig. 3) of maximum, pack in advance behind the regulating sleeve 5, reinstall bolt 8.Because bearing block 3 and wefting insertion, connect between the bearing block bottom outlet that latitude gear housing 2 matches, bolt 8 and wefting insertion connect the gap that reservation is arranged between the corresponding unthreaded hole on the latitude gear housing 2, behind four bolts, 8 pretensions, wear the off-centre rotation of bolt hole in the time of can utilizing regulating sleeve 5 rotations, realize the microdisplacement of double crosslinking gear shaft 6, the centre-to-centre spacing that reaches adjusting gear transmission transmission is regulated.
