Description

A kind of energy saving fuel-economizing speedy cotton spindles of bidirectional elastic

Technical field

The utility model relates to a kind of energy saving fuel-economizing of textile machine equipment technical field more particularly to bidirectional elastic high speeds Cotton spinning spindle.

Background technique

Cotton spinning spindle is one of main twisting winding component on spinning machine, is accustomed to the spinning spindle quantity to possess in the industry To measure the equipment scale and production capacity of spinning enterprise.Since entering international market with China's textile industry, in face of foreign countries The continuous impact of the labor cost and new product, new technology of developing country, the competition in product market are domestic The cotton spinning spindle of old model is no longer satisfied requirement of the client to product quality and production efficiency, current to hinder China's spinning frame High speed be first " light quantitative, slow train speed, high-quality " the inveteracy ideology problem of process management theory, with The continuous development of textile technology, high-speed automated is inexorable trend.

Therefore, the further innovation to cotton spinning spindle performance is also urgently pursued by textile enterprise.It is shown according to test data, mesh Preceding China's spinning speed generally maintains 16000r/min-22000r/min or so, and cotton spinning spindle energy consumption accounts for about spinning frame and always consumes 40% or so of energy, although the country has developed the novel flat ingot butt bolster structure using YD61, JW68, TXD51 type as representative Spindle has adapted to the requirement of frame high speed to a certain extent, but high-speed cruising still will appear Gao Zhen under actual condition Dynamic and high energy consumption issues, practical driving speed cannot still reach 25000r/min, therefore domestic and international major spindle manufacturing enterprise is Exploitation high speed, energy conservation, maintenance cost type spindle are classified as strategic objective.

Numerous textile enterprise have also done a large number of experiments, test, product type selection and administration of energy conservation to spindle spinning energy consumption and have worked, To reduce product cost, enterprise competitiveness is promoted.Under the joint efforts of many years of major textile enterprise, the machinery of cotton spinning spindle Performance achieves very big breakthrough and progress: cotton spinning spindle changes ingot from separate type tip spindle to elastic tube-type tip spindle Mechanical structure of the son from separate type to monoblock type, ensure that the concentricity of spindle, improve the unbalance dynamic under high speed；From bullet Property tubular type tip spindle to the flat ingot butt spindle of elastic tube-type change spindle high speed under axial ingot butt on alter vibration problem.Improve The high-speed resistance state of spindle pivot.But there is also following some not foot points:

1, that there are fuel consumption is big, single ingot power consumption is big for spindle；

2, stability of driving at a high speed under actual condition is poor, end breakage rate is high, spinning quality cannot be guaranteed；

3, spindle bearing lubricates under mist of oil cannot be guaranteed, easily cause dry friction, increase power consumption and noise；

4, unbalance dynamic of the spindle shaft disk engaging member under complicated power system causes to vibrate；

5, maintenance cost is high, service life is short；

6, the noise that spindle operation generates is big, and factory working environment is poor, influences worker's health.

In conclusion the high vibration under the flat ingot butt cotton spinning spindle high speed of the elastic tube-type being commonly used, high energy consumption etc. Instability problem still affects spinning quality and production efficiency.Therefore, a kind of stable high speed, energy saving cotton spinning spindle are developed With critically important realistic meaning.
