Technical field
The utility model belongs to field of textile machinery, and is especially relevant with a kind of high-speed and energy-saving two-for-one twisting spindles that is used for yarn twisting equipment.
Background technology
Two-for-one twisting spindles is one of core key part of two-for-one twister.Be sliding friction between at present at the bottom of the lower end supporting construction ingot point of two-for-one twister spindle and the ingot, frictional resistance is big, to making ingot point frictional heating; Part mechanical energy is converted into heat energy and is consumed; Ingot speed is high more, and thermal energy consumption is big more, makes that the spindle energy consumption accounts for about 80% of equipment total energy consumption in the double twisting equipment operation; The serious wear of part has simultaneously reduced spindle service life; The power transmission shaft of wharve part and the two-for-one twister tengential belt frictional drive power that reclines; Make the spindle rotation, the power transmission shaft diameter is more little, and the rotating speed of spindle just can be high more; But last supporting mechanism is positioned at the friction mandrel inner chamber of wharve; The diameter of power transmission shaft is just bigger relatively, and the highest per minute 13000 that also can only reach of ingot speed changes, and has restricted the raising of production capacity.
The utility model content
The purpose of the utility model be exactly for solve existing ingot point with at the bottom of the ingot between be the defective that the two-for-one twisting spindles energy consumption is big, the life-span lacks, rotating speed is not high relatively of sliding friction, a kind of long service life is provided, energy consumption is low, rotating speed is high.
For this reason; The utility model adopts following technical scheme: the high-speed and energy-saving two-for-one twisting spindles; Comprise spindle blade, wharve and installation supporting mechanism, wharve comprises frictional disk and the power transmission shaft two parts that are connected as a single entity, and frictional disk partly is used to support the bobbin cover that spindle is installed and realizes twisting with the friction yarn; Power transmission shaft part and the two-for-one twister tengential belt frictional drive power that reclines; Wharve is loaded on spindle blade through its central through hole fixed cover, it is characterized in that: described installation supporting mechanism comprises spring bearing, lower supporting bearing and bearing holder (housing, cover), and last spring bearing and lower supporting bearing inner ring fixed cover are loaded on said spindle blade and are positioned at the part below the power transmission shaft; Last spring bearing and lower supporting bearing are spaced a distance, and bearing holder (housing, cover) is set in the outer ring of spring bearing and lower supporting bearing.
As to such scheme replenish and perfect, the utility model also comprises following technical characterictic:
Described installation supporting mechanism also comprises bearing block and rubber spacer, and the rubber spacer is arranged between inner hole of bearing seat wall and the described bearing holder (housing, cover) outer surface, and forms and to closely cooperate, and the relative axial position of bearing holder (housing, cover) and bearing block is fixed.
Described rubber spacer is made up of last rubber spacer and following rubber spacer in pairs, and last rubber spacer is positioned at the described spring bearing outside of going up, and following rubber spacer is positioned at the outside of described lower supporting bearing.
Described bearing holder (housing, cover) outer surface is provided with annular groove; Described inner hole of bearing seat be provided with up end face by the shoulder; The described rubber spacer of going up is set in described annular groove; Last rubber spacer upper end relies on the upper side wall of annular groove, and the lower surface of last rubber spacer is pressed against described end face by shoulder, can play better supporting role to spindle blade.
Described upward rubber spacer becomes to be provided with the Rotary-table shape of centre bore, and described inner hole of bearing seat upper end cover is equipped with end cap, and end cap is provided with central through hole; The end cap lower surface is provided with annular projection, protruding axial cross section in echelon, protruding inboard cross section trapezoidal side is a hypotenuse; The protruding insertion between described upward rubber spacer and the inner hole of bearing seat surface; To go up the rubber spacer toward bearing holder (housing, cover) extruding, and make to contact bottom the annular groove on rubber sleeve and the bearing holder (housing, cover) closelyr, better play a supporting role.
Use the utility model can reach following beneficial effect: to form supporting mechanism through lower supporting bearing and last spring bearing are set; Sliding friction between replacing at the bottom of bolster and the ingot with rolling friction has reduced frictional heating greatly, has reduced wearing and tearing; Prolong service life, also reduced energy consumption; Shift out friction mandrel through going up spring bearing, can reduce the friction mandrel diameter, making ingot speed reach as high as per minute 17000 changes; Through the rubber spacer is set, can play cushioning effect between bearing holder (housing, cover) and bearing block; The energy-saving effect of comparing with existing spindle is about 15%, and the spindle rotating speed improves about 30%.
