Description

The high-speed and energy-saving spindle

[technical field]

The utility model relates to a kind of spindle of yarn twisting mill, and is relevant with a kind of high-speed and energy-saving spindle, belongs to the spindle technical field of yarn twisting mill.

[background technology]

Spindle comprises ingot sleeve pipe and spindle blade axis body, the ingot sleeve pipe is fixed on the frame plate of yarn twisting mill (as two-for-one twister) by two nuts up and down, the needle roller sliding bearing is housed in the top of spindle blade axis body, and be equipped with in its underpart the band opening columniform sliding sleeve, the spindle blade axis body is inserted in the ingot sleeve pipe, needle roller sliding bearing, sliding sleeve all cooperate with the spindle blade axis body is movable, then conflict with the sliding sleeve base plate in the bottom of spindle blade axis body, and whole spindle is supported by this sliding sleeve base plate.

By the tengential belt transmission spindle blade axis body is rotated, be sliding friction between spindle blade axis body and needle roller sliding bearing, the sliding sleeve, resistance is relatively large, power consumption is higher, the spindle blade axis body is high-speed rotary body, work temperature rise during running in its 24 hours, because sliding sleeve and spindle blade axis body fit clearance are little, more be unfavorable for heat radiation, need in the ingot sleeve pipe, to fill lubricating oil for this reason and safeguard, but its rotating speed of spindle still be in below the 11000r/min, so output is limited, greasy dirt also easily pollutes the yarn raw material, in case the short time is lost oil, namely can burn out sliding sleeve, spindle blade axis body bottom.

Spindle blade axis body bottom adopts sliding sleeve to cooperate, and operation stability is relatively poor, has restricted the further lifting of spindle rotating speed.

Its sliding sleeve base plate machining accuracy of integral type shift sleeve structure is low, in 24 hours long-time running processes of spindle blade axis body, spindle blade axis body bottom easy burn-out, the spindle blade axis body is consumable accessory, need periodic inspection to change, the spindle of a yarn twisting mill also has tens ingots hundreds of ingot at most less, and maintenance workload is big, the operating cost height.

[utility model content]

The deficiency that the utility model exists at above-mentioned prior art and provide that the rotary resistance of a kind of spindle blade axis body is little, operation stability is good, the work temperature rise is low and exempt from the high-speed and energy-saving spindle of lubricating maintenance.

For reaching above-mentioned purpose, solution of the present utility model is as follows:

The high-speed and energy-saving spindle, it is used for the yarn twisting mill, comprise the twisting dish, jockey pulley, spindle blade axis body and ingot sleeve pipe, jockey pulley is fixed in the twisting tray bottom, the spindle blade axis body passes jockey pulley, the twisting dish, and arrange with the jockey pulley tight fit, and the spindle blade axis body is removable to be loaded in the ingot sleeve pipe, its special improvement is: described ingot sleeve pipe upper end has tops bar, and a deep groove ball bearing is housed in its underpart, spindle blade axis body bottom deep groove ball bearing therewith is to roll and cooperates, on the described spindle blade axis body therewith corresponding position, the position tight fit of topping bar of ingot sleeve pipe another deep groove ball bearing is arranged, this another deep groove ball bearing is installed on this tops bar.

The periphery circle also is provided with the elasticity locking device inconsistent with above-mentioned another deep groove ball bearing in above-mentioned ingot sleeve pipe upper end, this elasticity locking utensil has two to handle knob, an axial line approximate vertical of handling knob with elasticity locking device, another is handled knob and then departs from the axial line of elasticity locking device.

After elasticity locking device was set, upwards string was moving to prevent the spindle blade axis body to play on the one hand locking spindle blade axis body, and spindle is unlikely when high speed rotating and flies out and the generation of contingency, the safe and reliable property of spindle height occur; On the other hand, turn on elasticity locking device, can easily easily spindle blade axis body and ingot sleeve pipe be realized separating, the convenient spindle blade axis body that detects.

The bearing holder (housing, cover) inconsistent with its inwall also is equipped with in above-mentioned ingot sleeve pipe bottom, and this bearing holder (housing, cover) has locating slot, and an above-mentioned deep groove ball bearing is restrained in this locating slot.

The ingot sleeve pipe is set up the bearing holder (housing, cover) that has locating slot in the bottom, and an above-mentioned deep groove ball bearing is fixing reliable, thereby has improved the rotational stabilization of long its bottom of spindle blade axis body.

Above-mentioned ingot sleeve pipe offers in its bottom and gets out of a predicament or an embarrassing situation, and above-mentioned getting out of a predicament or an embarrassing situation upward fixedly has bearing plate, and its bottom, above-mentioned spindle blade axis body bottom is supported on this bearing plate.

The independent bearing plate that arranges, simple in structure, easy to process, accuracy guarantee, spindle blade axis body bottom is easy burn-out not.

The utlity model has following beneficial effect:

1, spindle blade axis body and two deep groove ball bearings are to roll and cooperate, the quality of fit height, abandoned the traditional slip transmission of spindle blade axis body accordingly, replacing becomes the rolling transmission, reduce friction, reduce temperature rise and energy consumption, rotating speed significantly improves, and is suitable for long-time running under the high-speed working condition, because rotational resistance is minimum, has reached efficient, energy-conservation effect;

2, the spindle rotating speed carries out productivity running reposefully more than 16000r/min, thereby increases output, cut down the consumption of energy.Its speed of production can improve more than 35% than old-fashioned spindle under equal status of energy consumption, and energy consumption reduces more than 20%;

3, design bearing plate separately, need not fill lubricating oil in the ingot sleeve pipe of the present utility model, thoroughly stop waste oil to the opportunities for contamination of yarn, and the ingot sleeve pipe is interior because no sliding sleeve exists, ingot sleeve pipe heat-dissipating space is conducive to heat radiation greatly.
