Power Transmission Device of Jacquard Loom

Abstract

The present invention discloses a jacquard loom power transmission apparatus, and belongs to the technical field of jacquard loom power transmission. The jacquard loom power transmission apparatus comprises a loom main transmission shaft, a jacquard cock main shaft, a speed reduction transmission wheel and a connection rod, wherein the speed reduction transmission wheel and the connection rod are positioned on the same side of a loom wall plate and a jacquard cock wall plate, the loom main transmission shaft can be continuously and rotatably arranged on the loom wall plate in a penetrating manner, the jacquard cock main shaft is arranged on the jacquard cock wall plate in a penetrating manner, the jacquard cock main shaft is a swing shaft, movement of the loom main transmission shaft is transmitted to the speed reduction transmission wheel, the lower end of the connection rod forms a hinged connection on an eccentric hole arranged on the speed reduction transmission wheel, and the upper end forms a hinged connection with a connection rod swing arm fixedly connected on the jacquard cock main shaft. The jacquard loom power transmission apparatus has characteristics of low configuration cost, less transmission links, low transmission load, and low movement resistance so as to provide high transmission efficiency and substantially reduce power consumption. In addition, installation and maintenance of the apparatus are convenient, and operation cost of the Jacquard loom provided with the apparatus is low.

Description

【Technical field】 [0001] The invention relates to a power transmission device of a jacquard loom, which is used to transmit the power of the loom to a jacquard faucet, and belongs to the technical field of jacquard loom power transmission. 【Background technique】 [0002] Patent No. ZL201020294433.X discloses a jacquard faucet transmission device for a high-speed air-jet jacquard loom, including a main shaft of the loom, a pulley, a coupling (transverse cardan shaft), (lower) jacquard faucet transmission box, input shaft, output Shaft, (with universal joint) transmission vertical shaft, support, the end of the support is fixed with the wallboard of the jacquard loom, the jacquard faucet transmission box is fixed on the support, and the jacquard faucet transmission box is provided with a For the meshing bevel gears, the input shaft and the output shaft are respectively tightly connected with the two bevel gears, the main shaft of the loom is rigidly connected with the pulley, ...

AI Technical Summary

Problems solved by technology

[0005]1. There are many transmission links, and the transmission efficiency is low: the coupling (horizontal cardan shaft) rotates with the rotary motion of the main shaft of the loom, and passes through (below) The transmission box of the jacquard faucet is converted into the vertical rotary motion of the transmission vertical shaft, and the transmission vertical shaft is converted into the rotary motion of the horizontal axis through the upper jacquard faucet transmission box, so that the main drive shaft of the jacquard faucet rotates together. The relative reciprocating motion needs to be converted into the swing of the pendulum shaft by setting the main drive shaft of the jacquard faucet. Therefore, the power consumption required for the power transmission of the loom to the jacquard faucet is large.

[0006]2. The upper jacquard faucet transmission box and the transmission vertical shaft with universal joints account for 15% of the total cost price of the jacquard faucet; In the total cost price, the configuration (lower) jacquard faucet transmission box and coupling (horizontal cardan shaft) also occupy a certain proportion, so for jacquard loom users, the equipment investment cost is relatively high

[0007]3. The installation is cumbersome: because the main drive shaft of the jacquard faucet, the horizontal shaft and the shaft end on the lateral side of the upper jacquard faucet transmission box are connected by three shafts, so It is necessary to solve the problem of concentricity and use a level to adjust the levelness of the upper jacquard faucet transmission box, horizontal shaft and main drive shaft. Furthermore, it is also necessary to adjust the levelness of the (lower) jacquard faucet transmission box

[0008]4. Inconvenient use and maintenance: Since the transmission box of the upper jacquard faucet installed at a high position is operated under vibration and high temperature environment, there are accelerated oil seal aging and easy leakage Insufficient oil and short service life, high operating costs
