Product display and advantages
Main Feature :
The TONGDA novel high-speed and high-performancesspindle adopts innovated designs of HPS-68 insert incorporatingboth a
roller neck bearing and a sphero-point (convex) footstep bearing the convex footstep bearing consisting of a radial bearingwhich
functions hydrodynamiclly and an axial plane-thrust bearing to absorb the axial forces, the diameter of the neck bearingbeing
reduced to 06.8mm, the distance between the neck bearingand the footstep bearing being reduced to 100mm, and furtherreduc
tion of the wharve diameter, and etc., has been granted a lot of patents for our technologies. Compared with the conventionnal
common spindle incorporating the cone-point (conical-tip,pointeed) footstep bearing, such innovated designs naturally have the struLe tural advantages of stable operation, no axial displacemerht, less friction wear, high load supporting capability,better consi:stency,etc. Tongda group has further developed the excellent perfor mances of these genes by means of advanced and applicable technical equipment and fine manufacture.
·Extremely stable operation,particularly applicable to high speed
·Less energy consumption, low noise oil and labour saving.yield increasing
·Long service life, stable performance and better consistency
·Simple and convenient installation use and maintenance.

TD4000 SERIES
The insert of TD4000 series spinning spindle according to advanced HF structure principle, connects metal elastictube and with lengthwise buffer component.It has good effects of longitudinal vibration buffer and lateraal self-adjusting center which keeps more loading. less vibration,lower noise,longer life.
The spindle adopts advanced connecting structure of upper part. The upper part has good rigidity and strong ability of deformation resistance. Production according to international manufacturing standards improves the performance of compplete spindle. The spindle operates more smoothly while full load or half load.
The smallest diameter of spindle pulley could be 18.5mm; this can make it adapt to high speed and low consumption. Spindle will be more stable when it operates with steel footstep.
Steel footstep avoids oil leakage and breakage caused by casting flaw. Clean lubricant prolongs spindle life. Advanced structure design keeps long periodof oil replenishment and low maintenance costs This series spinning spindle is suitable for auto-doffing.With quality bobbin, the max operating speed of bare spindle is 18000rpm, and the max operating speedof aluminum plug spindle is 20000rpm.
High-precision processing, advanced manufacturing technology and strict quality controlment ensures the accuracy of insert making. It makes the spindlea more stable and suitable for high speed.
Optimum structural design and reasonable manufacturingtechnologyensurehighrotation accuracy and less deformation of elastic tube for a long timne We can design and manufacture the spindle for other specfications suitable for various kinds of spinning frame according to customers' requirements. Footsteps can install with spindlle rail coordinately.

TD7000 SERIES
TD7000 series spinning spindle is a kind of high-speed and high-performance spindle, which is equipped with the novel HPS-68 insert independently developed by our companyThe HPS-68 insert incorporates both a roller neck bearing and a convex footstep bearing, the convex footstep bearing consistsof a radial bearing which functions hydrodynamiclly and an axijal plane-thrust bearing to absorb the axial forces. As the innerdiameter of the neck bearing is 6.8 mm, it has been possibleto reduce the whorl diameter to even smaller. The blade is very sshort and consequently extremely rigid. The forces acting radiaally in the area of the footstep bearing are absorbed by a genuine hhydrodynamic radial bearing. The sphero-point of the blade runson a free-sitting flat disc, which resists axial forcesCThe entire fopotstep bearing is housed in an elastic sleeve,even the slightest eccentric movements are damped by means of the oilcoil. Neck bearing geometry which has been modifiedd in the micro-range lends additional stability to spindle operation. The useof sophisticated new-type advanced and applicable production lines with mature modern equipment ensures a high degree of precision.Very little play, held to close tolerances, is provided in neck arnd footstep bearings,and this has a positive influence on spindle running.Such a footstep bearing design offers substantial advan tages in particular for high speeds and axial loards.
The aluminum rod made of high-strength and superhard aluminum alloy is hold by the spindle blade and the wharve from inside and outside,has good rigidity, can not loosen to move, and thuus can effectively resist external impact deformation. The spinddle insert adopts reliable axial overload protection to resist impactwithout subsidence and is suitable for push-down pipe insertieon of integral auto-doffing. The optimized design of the yarn cutter leads tohigh doffing yarn reserve rate. The use of a yarn gripper can realize doffing with zero winding and no end yarns.The accurate fit between the spindle bolster and the rail of the spinniing frame ensures good verticality of the spindle to realize non-correction installation The spindle is targeted at domestic and foreign high levelcustomers, is widely applied to high-speed spinning, spinnirng high-quality yarns,compact spinning, integral auto-doffing andspeed increase reform of a spinning frame, and the highest working speed of the spindle can reach to 25000rpm.The aluminum plug can be adjusted in type and size accordingto customer's requirements to allow customers to fit different types and sizes of bobbins.
