Description

The actuating unit of jacquard weaving machine
[technical field]
The utility model relates to a kind of actuating unit of jacquard weaving machine, is used for giving the jacquard weave tap with the loom transmission of power, belongs to jacquard weaving machine power transmission technical field.
[background technology]
Patent No. ZL201020294433.X discloses a kind of jacquard weave tap transmission device of high speed jet jacquard weaving machine, comprise loom main shaft, belt pulley, shaft coupling (horizontal universal drive shaft), (descending) jacquard weave tap transmission case, power shaft, output shaft, (the band universal joint) transmission vertical shaft, bearing, the wallboard of described bearing end and jacquard weaving machine is fixed, described jacquard weave tap transmission case is fixed on the bearing, be provided with a pair of angular wheel that is meshed in this jacquard weave tap transmission case, power shaft is held tightly with two angular wheels respectively with output shaft and is connected, described loom main shaft and belt pulley are rigidly connected, power shaft passes through active joint, shaft coupling and belt pulley are rigidly connected, output shaft is connected with transmission vertical shaft one end by active joint, and the described transmission vertical shaft other end is connected with the jacquard weave faucet device.
Furtherly, jacquard weave tap transmission device in the prior art also disposes jacquard weave tap transmission case and trunnion axis (all not drawing among the figure), last jacquard weave tap transmission case is to be installed on the bottom framework of jacquard weave tap, the described transmission vertical shaft other end (i.e. upper end universal joint) links to each other with the axle head that stretches out in jacquard weave tap transmission case below by active joint, and trunnion axis one end links to each other with the axle head that stretches out in the horizontal side of jacquard weave tap transmission case by shaft coupling, the trunnion axis other end then links to each other with final drive shaft one end of jacquard weave tap by another shaft coupling, by between the final drive shaft of jacquard weave tap and balance staff, eccentric wheel connecting rod mechanism being set, and griffe between frame and the balance staff elevating lever to be set at two groups, swing arm, the continuous gyration of jacquard weave tap final drive shaft could finally be converted into two groups of doing relatively reciprocating motion up and down of griffing.
Yet there is following weak point in this device:
1, transmission link is many, transmission efficiency is low: shaft coupling (horizontal universal drive shaft) is along with the gyration of loom main shaft is rotated together, be converted into the vertical gyration of transmission vertical shaft by (descending) jacquard weave tap transmission case, the transmission vertical shaft makes the final drive shaft of jacquard weave tap follow rotation together by the gyration that last jacquard weave tap transmission case is converted into trunnion axis again, and, two groups of doing relatively reciprocating motion up and down of griffing need be the swing of balance staff with the conversion of motion by the final drive shaft that the jacquard weave tap is set, therefore, the loom transmission of power gives the required power consumption of jacquard weave tap big.
2, the transmission vertical shaft that disposed last jacquard weave tap transmission case, has a universal joint occupied the jacquard weave tap the totle drilling cost price 15%; And in the totle drilling cost price of loom, disposed (descending) jacquard weave tap transmission case, shaft coupling (horizontal universal drive shaft) and also be occupy a certain proportion of, so for jacquard weaving machine with family, the equipment input cost is higher relatively.
3, installation is loaded down with trivial details: because the axle head of the final drive shaft of jacquard weave tap, trunnion axis and the horizontal side of last jacquard weave tap transmission case is that three axles link together, so need to solve the concentricity problem with the levelness of jacquard weave tap transmission case, trunnion axis and final drive shaft in the level meter adjustment, moreover, the levelness that also needs to regulate (descending) jacquard weave tap transmission case.
4, use, safeguard inconvenience: because high-order the last jacquard weave tap transmission case of installing operates under vibration operating mode, the hot environment, exist accelerate that oil sealing is aging, easy oil leakage and service life weak point deficiency, the operating cost height.
In view of above-mentioned analysis, existing transmission device is demanded urgently improving.
[utility model content]
The technical problems to be solved in the utility model be to overcome the deficiencies in the prior art and provide that a kind of deployment cost is low, drive mechanism is succinct, the actuating unit of power consumptive province, jacquard weaving machine convenient for installation and maintenance.
