Abstract
The utility model provides a spindle with a spindle blade in contact with bearing outer circles, and belongs to the field of spinning machine components. A supporting bearing of an existing spindle can be damaged easily. The spindle comprises the spindle blade, a spindle whorl, a belt wheel and a supporting mechanism, wherein the supporting mechanism comprises a bearing seat, a lower supporting bearing and at least three upper supporting bearings. The lower supporting bearing is arranged at the lower end of the spindle blade in a sleeved mode and mounted at the lower end of an inner cavity of the bearing seat, the belt wheel is mounted on the spindle blade in a sleeved mode, the spindle whorl is arranged at the upper end of the spindle rod in a sleeved mode, the upper supporting bearings are mounted on the top of the bearing seat through small shafts in a supporting mode, the axis of each small shaft is parallel to the axis of the spindle blade, the small shafts are arranged with the spindle as the center in the circumference direction, and the out circles of the upper supporting bearings abut against the spindle blade. According to the spindle, operation speed of the bearings is greatly lowered, and the service life of the upper supporting bearings is prolonged.
Description
Technical field
The utility model belongs to spinning machine part device field, especially relevant with a kind of spindle.
Background technology
Spindle is one of core key part of spinning machine.Spindle comprises spindle blade, wharve and supporting mechanism, be set in the upper end of spindle blade with the wharve of frictional drive axle, the lower end of spindle blade is fixed by supporting mechanism, make the spindle blade upper end that is set with wharve be cantilevered, supporting mechanism comprises upper support bearing, lower supporting bearing and bearing block, spindle blade supports and is installed in bearing block by upper support bearing and lower supporting bearing, because spindle blade is to be installed in bearing cone.Compress the frictional drive axle by tengential belt and drive the spindle blade rotation, the spindle blade upper end is produced to radial load, make the upper support bearing be subject to larger radial load, the frictional force of bearing is also just relatively large, in the spindle operation process, the spindle blade rotating speed is generally very fast, and bearing is also followed High Rotation Speed, under larger frictional force effect, runs up, can reduce the service life of bearing, thus the running of bearing indirectly limited the exploitation speed of spindle blade can not be too fast.The upper support bearing holder (housing, cover) is loaded on spindle blade, changes bearing as need and need to pull down whole spindle blade, changes inconvenience, often occurs just need scrapping whole spindle after the upper support bearing damage, improves the use cost of equipment.
The utility model content
The purpose of this utility model is intended to overcome existing spindle upper support bearing and holds flimsy defect, provides a kind of and can extend the bearing bearing outer ring contact spindle blade formula spindle in service life.
For this reason, the utility model is by the following technical solutions: a kind of bearing outer ring contact spindle blade formula spindle, comprise spindle blade, wharve, belt wheel and supporting mechanism, supporting mechanism comprises bearing block, upper support bearing and lower supporting bearing, lower supporting bearing is set in the spindle blade lower end and is installed on the lower end of bearing block inner chamber, belt wheel is set on spindle blade, wharve is set in the upper end of spindle blade, it is characterized in that, described upper support number of bearings is at least three, the upper support bearing supports and is installed on the bearing block top by little axle, the axis of little axle is parallel with the axis of spindle blade, little axle circumferential array centered by spindle blade, outer ring and the spindle blade of upper support bearing are inconsistent.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic.
Quantity the best of described upper support bearing is three.
Described upper support bearing circumference equal dividing centered by spindle blade is arranged.
Described bearing block top is provided with opening up groove as the bearing installation cavity, and described upper support bearing is arranged in this bearing installation cavity, and the bottom that is installed on this bearing installation cavity is supported in the lower end of described little axle by shock-absorbing sleeve.
The top of described bearing installation cavity, by seal cap sealing, makes the upper support bearing in sealing state.
Described belt wheel is between upper support bearing and lower supporting bearing, and the sidepiece on bearing block is provided with the opening connected with the bearing block inner chamber, and belt wheel has the part more outstanding than described open bottom, and the outstanding part of belt wheel can be reclined mutually with tengential belt.Be arranged between upper support bearing and lower supporting bearing by the position by belt wheel, make shaft strength even up and down.
Described bearing block is axial double split-type structural, and two parts of bearing block are fixedly connected with by screw, only need unclamp screw during maintenance and take bearing block apart, convenient for maintaining.
Use the utility model can reach following beneficial effect: the utility model has changed the supporting way of upper support bearing, outer ring and spindle blade by bearing are inconsistent, be converted to bearing outer ring and contact with spindle blade because the inner ring of bearing contacts with spindle blade, the running speed meeting decrease of bearing, the service life of having improved the upper support bearing; Be arranged between upper support bearing and lower supporting bearing by the position by belt wheel, make shaft strength even up and down, improved the stability of spindle.
