Abstract

The invention discloses a connecting shaft bearing used for a shaft of a chemical fiber high-speed spinning winding head chuck. The connecting shaft bearing is characterized in that a core shaft (1) is directly provided with a standard bearing, the standard bearing is positioned through a shaft shoulder (12) of the core shaft and a clamp ring (10), a check ring (7), an outer sleeve (6) and the like, and the processing difficulty of the core shaft is reduced; and meanwhile, a chuck shaft of a chemical fiber high-speed spinning winding head can rotate at a high speed with high precision, and the chaining reliability and working stability of the whole connecting shaft bearing are guaranteed.

Description

A kind of axle that is used for chemical fibre high-speed spinning wrapping head chuck is used Coupling bearing

Technical field

The present invention relates to a kind of bearing, particularly a kind of axle that is used for chemical fibre high-speed spinning wrapping head chuck is used Coupling bearing, belongs to the mechanical transmissioning technology field.

Background technique

Piece bearing is widely used in spinning equipment on a chuck, and initial structure is that inner ring raceway directly is processed on the mandrel, and processing is relatively more difficult like this.

As improvement; Patent of invention " piece bearing mandrel " like patent No. ZL200520107450.7 its objective is through standard rolling bearing to be sleeved on the mandrel, has simplified the difficulty of production and processing technology; Thereby guarantee that operation technique requires to make such import commonly use product under the consistent situation and can domesticize; Though but its deficiency is to only depend on a locating piece can satisfy the rotation needs, can not guarantee highi degree of accuracy, high speed rotating, and the reliability of its connection, working stability is all relatively poor.

The patent of invention of patent No. ZL200720122920.6 discloses a kind of " chemical fibre high-speed spinning wrapping head chuck axis is used the Coupling bearing assembly "; Though it remedies the deficiency of " piece bearing mandrel "; But bring " piece bearing mandrel " settled problem, increase and produce and the processing technology difficulty.

Summary of the invention

Technical problem to be solved by this invention provides a kind of axle that is used for chemical fibre high-speed spinning wrapping head chuck and uses Coupling bearing, this Coupling bearing can not only guarantee reliable work stability, and can also reduce the processing technology difficulty.

In order to solve above-mentioned technical problem; Technological scheme of the present invention is: a kind of axle that is used for chemical fibre high-speed spinning wrapping head chuck is used Coupling bearing; Comprise mandrel and be sleeved on the standard rolling bearing on the mandrel; Said standard rolling bearing is divided into first standard rolling bearing and second standard rolling bearing; Said first standard rolling bearing, second standard rolling bearing are installed in the shaft shoulder place at mandrel two ends respectively, and the two ends of the first standard rolling bearing inner ring are fixed through the clamp ring and the shaft shoulder, and the two ends of the second standard rolling bearing inner ring are fixed through the back-up ring and the shaft shoulder; Arranged outside at mandrel, first standard rolling bearing and second standard rolling bearing has outer sleeve; At mandrel shaft shoulder place; The outer sleeve inboard is provided with protuberance; Both sides, the first standard rolling bearing outer ring are fixed through the first axle head end cap and protuberance, and both sides, the second standard rolling bearing outer ring are fixed through the protuberance and the second axle head end cap.

Be provided with disk spring and adjustment pad between said first standard rolling bearing outer ring and the protuberance.

The present invention has reduced the processing technology difficulty of mandrel through using standard rolling bearing, and the shaft shoulder that makes full use of mandrel is located the outer ring of standard axle with the axle head end cap, makes this Coupling bearing can satisfy the requirement of highi degree of accuracy, high rotating speed, stable working, and simple in structure.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.

Accompanying drawing is a structural representation of the present invention.

Embodiment

Existing Coupling bearing precision is low, rotating speed is slow and processing technology is difficult; For overcoming this problem; Coupling bearing of the present invention comprises mandrel 1 and is sleeved on the standard rolling bearing on the mandrel 1 that said standard rolling bearing is divided into first standard rolling bearing 4 and second standard rolling bearing 8 shown in accompanying drawing; Said first standard rolling bearing 4, second standard rolling bearing 8 are installed in the shaft shoulder 12 places at mandrel 1 two ends respectively, and first standard rolling bearing 4, second standard rolling bearing, 8 inner rings replace raceway in the standard rolling bearing that original mandrel bearing itself provided.

The two ends of first standard rolling bearing, 4 inner rings are fixing with the shaft shoulder 12 through clamp ring 10, and the two ends of second standard rolling bearing, 8 inner rings are fixing with the shaft shoulder 12 through back-up ring 7; Arranged outside at mandrel 1, first standard rolling bearing 4 and second standard rolling bearing 8 has outer sleeve 6; At mandrel 1 shaft shoulder 12 places; Outer sleeve 6 inboards are provided with protuberance 13; Both sides, first standard rolling bearing, 4 outer ring are fixing with protuberance 13 through the first axle head end cap 3, and the first axle head end cap 3 can also carry out fastening through Cock screw 2.Both sides, second standard rolling bearing, 8 outer ring are fixing through the protuberance 13 and the second axle head end cap 9.

Be provided with disk spring 5 and adjustment pad 11 between said first standard rolling bearing, 4 outer rings and the protuberance 13, can suitably regulate the displacement between first standard rolling bearing, 4 outer rings and the protuberance 13.

The foregoing description does not limit the present invention in any way, and every employing is equal to the technological scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
