Abstract
A chemical fiber high speed winding head holding chuck axle shaft bearing assembly; which solves the deficiency of the present technology; namely only one bearing connection hole is used to transmit power, support and rotate, the winding head holding chuck high precision high speed rotation can not be guaranteed. The utility model is characterized in that the dish-shaped spring 13 and adjusting gasket 14 are arranged inside the outer cover 6, the inner ring of the bearing 5 is sleeved on the axle 12. a ''O'' shaped sealing ring 4 is pressed between the end cover 2 and the bearing 5. A locking ring 3 is closely attached to the inner ring of the bearing 5; and an end cover (10)is attached to the outer ring (8). A key slot 1 can be made on the left end of the hollow or solid axle 12. Because of the dish-shaped spring 13 and the adjusting gasket 14, the force on the bearing can be adjusted, the bearing outer ring can be guaranteed to float within the outer cover with a minimum space, and without rotation; then the bearing part rotating precision is improved, the work rotating speed can reach 18000 r/min, and can continuously operate for over 9000 hours. The two bearings form two rotating support points, which are reliable and stable. The dish-shaped spring 13 eliminates the clearance of the two bearings. The bearing assembly is applicable to chemical fiber high speed winding head holding chuck axle.
Description
Technical field
The utility model relates to a kind of Coupling bearing assembly, particularly a kind of chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly.
Background technology
Chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly of the prior art, as the patent No. be: 00222417.8, utility model patent " chemical fibre high-speed spinning winding head chuck axis special-purpose Coupling bearing ", its objective is to guarantee that chemical fibre high-speed spinning winding head chuck axis rotates with high-precision high-speed.Its structure is that " place steel ball 7 off-centre in the nylon cages 11 to place between outer ring 8 and the axle 12, rubber seal 9 places that nylon cages is 11 outer, between the outer ring 8 and spools 12.In axle 12, be provided with internal thread cylinder connecting hole ".Though it also can satisfy the rotation needs of chemical fibre high-speed spinning winding head chuck axis, but its weak point is internal thread cylinder connecting hole transferring power, support and the rotation that only depends in a bearing and the axle 12, can not guarantee that chemical fibre high-speed spinning winding head chuck axis is with high accuracy, rotation at a high speed; Its connection reliability, job stability, functional reliability are all relatively poor in addition.
Summary of the invention
In order to solve above-mentioned weak point of the prior art, the purpose of this utility model provides a kind of chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly.Technical solution of the present utility model is:
1. the nearly left end at overcoat 6 is built-in with disk spring 13 and adjusting pad 14, and the inner ring of bearing 5 is placed on the axle 12.Between end cap 2 and bearing 5, be pressed with " O " RunddichtringO 4.Clamp ring 3 is fitted with the inner ring of bearing 5.Left end at axle 12 has keyway 1.End cap 10 is fitted with outer ring 8.This is the chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly of real core, band keyway 1;
2. the nearly left end at overcoat 6 is built-in with disk spring 13 and adjusting pad 14, and the inner ring of bearing 5 is placed on the axle 12.Between end cap 2 and bearing 5, be pressed with " O " RunddichtringO 4.Clamp ring 3 is fitted with the inner ring of bearing 5.End cap 10 is fitted with outer ring 8.This is real core, not with the chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly of keyway 1;
3. the nearly left end at overcoat 6 is built-in with disk spring 13 and adjusting pad 14, and the inner ring of bearing 5 is placed on the axle 12 of hollow.Between end cap 2 and bearing 5, be pressed with " O " RunddichtringO 4.Clamp ring 3 is fitted with the inner ring of bearing 5.Left end in air-cored axis 12 has keyway 1.End cap 10 is fitted with outer ring 8.This is the chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly of hollow, band keyway 1;
4. the nearly left end at overcoat 6 is built-in with disk spring 13 and adjusting pad 14, and the inner ring of bearing 5 is placed on the axle 12 of hollow.Between end cap 2 and bearing 5, be pressed with " O " RunddichtringO 4.Clamp ring 3 is fitted with the inner ring of bearing 5.End cap 10 is fitted with outer ring 8.This is hollow, not with the chemical fibre high-speed spinning winding head chuck axis Coupling bearing assembly of keyway 1.
The advantage that the utility model is had compared to existing technology is: owing to be built-in with disk spring 13 and adjusting pad 14 at the nearly left end of overcoat 6, put on the adjustable size of the pretightning force of bearing, and can be constant, can guarantee simultaneously that bearing outer ring floats in overcoat with minimum gap, but can not rotate at work, improved the running accuracy of bearing assembly, working speed can reach per minute 18000 to be changeed, and can run well continuously more than 9000 hours.Two bearings are formed two pivot points, reliably stablize.Disk spring 8 is eliminated the two bearings play, and is simple in structure.
