Abstract
Spindle is a key component for high speed rotation of spinning frames or twisting machines. The performance quality of the spindle influences the quality of the spinning or the twist directly. The utility model provides a kinetic pressure bearing spindle. A helical groove is arranged on the cone surface of the blade point. The damp dry friction state of the support of the original structure is changed to liquid lubrication state, and the oil film is provided with certain radial direction carrying capacity. Therefore, blade point grind can be reduced by avoiding direct contact, and vibrating stability can be improved. Amplitude is reduced.
Description
The utility model provides a kind of hydrodynamic bearing spindle, belongs to mechanical field.
Spindle is the critical component that rotates at a high speed on fine spining machine or the twisting machine, quality and output that the good and bad directly influence of its performance spins.At present, employed spindle on the reeler, upper support adopts rolling bearing, is rolling friction, and lower support is a sliding bearing, is half-dried abrasion state.It is big that this structure exists energy consumption, and the problem that the life-span is low, the power consumption of spindle about 80% of the reeler Overall Power Consumption that accounted for because of lower support is half-dried abrasion state, so often lost efficacy because of the lower support wearing and tearing make a whole set of spindle.In addition, radially bearing capacity is poor at spindle lower support position, thus when revolution amplitude bigger, the direct influence quality that spins.
The utility model provides a kind of hydrodynamic bearing spindle, and the half-dried abrasion state that becomes the original structure lower support has improved stability of vibration into the hydrodynamic lubrication state, has prolonged the service life of spindle.
The utility model is achieved in that under spindle blade on the taper seat of point (hereinafter to be referred as the ingot point) and engraves helicla flute, cause in use, the spindle bottom is dipped in the oil, according to the fluid lubrication theory, during the spindle rotation, because the spiral fluted effect, oil is rushed for the ingot point, oil pressure is formed at ingot point bottom, and upper part of spindle is held up, the ingot point with at the bottom of the ingot between the very thin oil film of formation one deck and reach the hydrodynamic lubrication state.
Description of drawings:
Fig. 1 is a hydrodynamic bearing spindle general assembly drawing.
Fig. 2 is an ingot point enlarged diagram.
Fig. 3 is the ingot point enlarged diagram with secondary tapering.
By accompanying drawing as can be seen, the hydrodynamic bearing spindle is made up of spindle blade 1, upper bearing (metal) 2, wharve 3, ingot point 4, and helicla flute 5 is arranged on the ingot point 4, and these helicla flutes 5 can be that some roads are symmetrically distributed.The cross section of the helicla flute 5 on the ingot point 4 can be made multiple shape, can be rectangle, can be trapezoidal, also can be triangle, can also be circular arc.Helicla flute 5 on the taper seat of ingot point 4, the shape of cross section can be the combinations of two or more shape arbitrarily in rectangle, trapezoidal, the triangle.The circular cone of ingot point 4 also can have repeatedly tapering, on a plurality of conical surfaces, can only carve helicla flute 5 on a conical surface, also can carve helicla flute 5 on several conical surfaces.On two conical surfaces, be carved with helicla flute 5 simultaneously exactly as Fig. 3.In use, because of the Lower Half of whole spindle is dipped in the lubricating oil, so when spindle rotates, because the spiral fluted effect is rushed for ingot point bottom with oil, forms oil pressure, the spindle upper part of spindle is held up, reach the hydrodynamic lubrication state forming the very thin oil film of one deck between 6 at the bottom of ingot point and the ingot.Because of this structure when spindle rotates, the ingot point separates with at the bottom of the ingot, the half-dried abrasion state that becomes the friction of original structure lower support is the hydrodynamic lubrication state, and oil film has certain radially bearing capacity, therefore both can avoid directly contacting and reducing wear, can improve the stability of vibration again, reduce amplitude, reduce the power consumption of spindle.
