Description
Technical field
The utility model belongs to Special Parts for Spinning Frames technical field, is specifically related to the spindle structure that a kind of lower support is rolling bearing.
Background technology
Along with textile industry industrial upgrading, technological progress is accelerated, market competition is aggravated, textile enterprise proposes requirements at the higher level to fine spining machine, and spindle is the critical component of high speed rotary on fine spining machine, it is the critical piece of fine spining machine twisting winding, therefore the performance of spindle and the quality of life-span decision spinning, efficiency, energy consumption and cost, China is a weaving big country, the high speed of spindle, efficiently, steadily, low-loss and energy-saving seems even more important, the lower support of current spindle mainly contains two kinds of forms: a kind of be bottom spindle blade be taper taper ingot at the bottom of support, another kind is supporting construction at the bottom of the flat ingot adopting plane thrust and bush(ing) bearing to form, easily axial float is there is in taper ingot bottom structure spindle in operation process, spindle blade departs from center and causes low-frequency vibration, the problems such as high stability difference, ingot speed can only at below 18000r/min, energy consumption high efficiency is low, and flat ingot bottom structure fixes tile-type hydrodynamic bearing due to the simgle oil wedge adopted, the dynamic pressure oil film bearing capacity of generation is little, discontinuous, and centering precision is low, and lubrication is in the semi-liquid lubrication state of incomplete lubrication, and friction and wear is larger.
Utility model content
The utility model overcomes the deficiency that prior art exists, and aims to provide a kind of energy-conservation, long-life, the fine spining machine spindle of high reliability.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: adopt the New spindle that deep groove ball bearing supports at the bottom of a kind of ingot, rise in bolster Elastic pipe at the bottom of the ingot of lower support and have rolling bearing successively from top to bottom, prop up block and spring formation, the lower cone point of spindle blade is inserted on the inner ring of described rolling bearing, under the effect of block 5 spring 6 elastic force below, its top annular boss withstands on the outer ring of bearing bottom, ensure to keep suitable compact stress with the lower ingot point of spindle blade on the upside of bearing cone hole, main feature is that the lower cone point of spindle blade is inserted on rolling bearing inner ring hole, namely spindle blade lower cone point and bearing cone top be linear contact lay, under elastic tube and the gravity of spindle blade and the acting in conjunction of spring force, the lower cone point of spindle blade remains with rolling bearing inner ring and contacts, prevent from skidding, owing to adopting roller bearings, greatly reduce frictional dissipation, make full use of the automatic centering function in spindle blade lower cone and bearing cone hole, and the accuracy of manufacture of boring point under spindle suitably reduces spindle blade can be reduced, hardness and roughness, the adaptation high speed of spindle can be realized, high reliability, energy-conservation, long-life.Because the support component bottom spindle blade adopts rolling bearing, greatly reduce frictional dissipation and the power consumption of spindle, decrease the consumption of spindle lubricant simultaneously, extend the maintenance cycle, achieve the high speed of spindle, energy-conservation and long-life, extend the maintenance period of spindle, reduce maintenance workload, the overall performance of fine spining machine spindle is had very large improving.
Described block is the disc-shaped part that annular boss is arranged at top, and its lower plane directly contacts with spring, and described upper, annular boss withstands on the outer ring of rolling bearing under the elastic force effect of spring.
Described block is a stepped cylindrical component, annular boss above this part large diameter portion, the path of described cylindrical component is enclosed within the endoporus of spring, and the annular boss in the large footpath of described cylindrical component withstands on the outer ring of rolling bearing under the elastic force effect of spring.
Described rolling bearing is common high speed light loading deep groove ball bearing.
In addition, according to the needs of actual production, rolling bearing is preferably common underloading high speed deep groove ball bearing, standard, good economy performance, long service life.
The utility model make spindle blade lower cone point and bearing cone top be linear contact lay, under elastic tube and the gravity of spindle blade and the acting in conjunction of spring force, the lower cone point of spindle blade remains with rolling bearing inner ring top and contacts, prevent from skidding, make full use of the automatic centering function on the upside of the lower cone of spindle blade and rolling bearing inner ring circular hole, the automatic aligning of spindle can be realized, minimizing spindle blade alters problem, improve the running accuracy of spindle, and under spindle can be reduced, bore precision and the roughness of point.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 to be block be stair-stepping cylindrical time structural representation.
Detailed description of the invention
Be described in further detail the utility model by reference to the accompanying drawings now, accompanying drawing is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of fine spining machine spindle, rise in bolster 3 Elastic pipe 1 at the bottom of the ingot of lower support and have rolling bearing 4 successively from top to bottom, block 5 and spring 6 are formed, the lower cone point of spindle blade 2 is inserted on the inner ring of rolling bearing 4, the lower cone point of spindle blade 2 is inserted on the inner ring hole of rolling bearing 4, namely spindle blade 2 lower cone point and rolling bearing 4 inner ring top be linear contact lay, under elastic tube 1 and the gravity of spindle blade 2 and the acting in conjunction of spring 6 elastic force, the lower cone point of spindle blade 2 remains with rolling bearing 4 inner ring and contacts, prevent from skidding, make full use of the automatic centering function on the upside of the lower cone of spindle blade 2 and rolling bearing 4 inner ring circular hole, the automatic aligning of spindle can be realized, reduce the upper string problem of spindle blade 2, improve the running accuracy of spindle, and precision and the roughness of spindle blade 2 times cone points can be reduced, rolling bearing 4 form is adopted owing to supporting, greatly reduce spindle frictional dissipation and power consumption, the loss of bobbin oil can be reduced, the aspects such as maintenance are had greatly improved, the realization high speed of spindle can be realized, high reliability, energy-conservation, long-life, the performance of fine spining machine spindle is made to improve a lot in addition, the utility model makes full use of the automatic centering function between the hypocentrum of spindle blade 2 and rolling bearing 4 inner ring circular hole, the automatic aligning of spindle can be realized, reduce the upper string problem of spindle blade 2, improve the running accuracy of spindle.
Block 5 has the disc-shaped part of annular boss for top, and its lower plane directly contacts with spring 6, and upper, annular boss withstands on the outer ring of rolling bearing 4 under the elastic force effect of spring 6, or
Propping up block 5 is a stepped cylindrical component, annular boss above this part large diameter portion, the path of cylindrical component is enclosed within the endoporus of spring 6, and the annular boss in the large footpath of cylindrical component withstands on the outer ring of rolling bearing 4 under the elastic force effect of spring 6.
