Abstract
The invention provides a leather roller central spindle. The leather roller central spindle comprises a housing with an inner chamber, and a fixing shaft rotatingly arranged in the inner chamber of the housing via clamping connection; the wall surface of the inner chamber of the housing is a spherical surface; the fixing shaft comprises a spherical part, and a shaft rod connected with the spherical part; and the spherical part is arranged in the inner chamber, and cooperation rotating of the spherical part with the spherical surface of the inner chamber is realized. The structure of the leather roller central spindle is simple; rotation is flexible; abrasion is not easily caused; service life is long; and application prospect is promising.
Description
Technical field
The present invention relates to Weaving device field, relate more specifically to a kind of roller mandrel.
Background technology
In Weaving device field, roller mandrel is a kind of conventional accessory, in existing roller mandrel, formed by two in-line gears spelling groups side by side, in long-term use procedure, bearing wear is more severe, service life is short, thereby need often to change, increase production cost, and greatly reduced operating efficiency, thereby need to improve the roller mandrel of this kind of design, overcome its existing shortcoming.
Summary of the invention
For overcoming the problems referred to above of the prior art, the invention provides a kind of roller mandrel, it is simple in structure, by with fixed axis clamping, reduced wearing and tearing, long service life.
The present invention has adopted following technical scheme:
A kind of roller mandrel, comprises the fixed axis in the inner chamber that has the shell of inner chamber and be located at shell, and fixed axis is connected in the inner chamber of shell rotationally.
Further, the wall surface of the inner chamber of shell is spherical, and fixed axis comprises spherical portion and the axostylus axostyle being connected with spherical portion, and spherical portion is arranged in inner chamber, and can coordinate rotation with the spherical wall of inner chamber.
Further, spherical portion can be around 360 ° of rotations of its axial line in inner chamber.
Further, when spherical portion is rotated, its axial line tiltable 1-15 °.
Preferably, when spherical portion is rotated, its axial line tiltable 10-15 °.
Due to spherical portion and shell sphere-contact the rotation of main shaft, thereby can within the scope of certain angle, do banking motion, the slight direction spinning can adapt to Weaving device work time changes.
Beneficial effect of the present invention:
The invention provides a kind of roller mandrel, it is simple in structure, and main shaft and shell rotate by sphere clamping, rotates flexibly, and has avoided the heavy wear of in-line gears of the prior art, and durable, has a good application prospect.
Brief description of the drawings
Fig. 1 is the structural representation of roller mandrel of the present invention.
Fig. 2 is the cross-sectional schematic of roller mandrel of the present invention.
Fig. 3 is the schematic top plan view of roller mandrel of the present invention.
In figure: 1, shell; 2, fixed axis; 21, spherical portion; 22, axostylus axostyle.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is described in further detail.
Consult Fig. 1-Fig. 3, shown a kind of roller mandrel in figure, comprise the fixed axis 2 in the inner chamber that has the shell 1 of inner chamber and be located at shell 1, fixed axis 2 is connected in the inner chamber of shell 1 rotationally. The wall surface of the inner chamber of shell 1 is spherical, and fixed axis 2 comprises spherical portion 21 and the axostylus axostyle 22 being connected with spherical portion 21, and spherical portion 21 is arranged in inner chamber, and can coordinate rotation with the spherical wall of inner chamber. Spherical portion 21 can be around 360 ° of rotations of its axial line in inner chamber. When spherical portion 21 is rotated, 15 ° of its axial line tiltables. That is, rotate simultaneously in shell 1 at fixed axis 2 around 360 °, himself axis, can also tilt in any one position, like this, what just can adapt to spin slightly beats.
In the present invention, by the rotation that coordinates of the spherical portion 21 of fixed axis 2 and the spherical surface inner chamber of shell 1, fixed axis 2 can tilt slightly in the inner chamber of shell 1, rotate flexibly, and the wearing and tearing of coaxial two gears of the prior art are avoided, greatly extend service life, reduced operating cost, and greatly improved operating efficiency.
Above specific embodiment of the present invention is illustrated; but protection content of the present invention is not only limited to above embodiment; under of the present invention, in technical field, the common knowledge of a GPRS just can be carried out diversified change within the scope of its technology main idea.
The invention provides a kind of roller mandrel, comprise the fixed axis in the inner chamber that has the shell of inner chamber and be located at shell, fixed axis is connected in the inner chamber of shell rotationally. The wall surface of the inner chamber of shell is spherical, and fixed axis comprises spherical portion and the axostylus axostyle being connected with spherical portion, and spherical portion is arranged in inner chamber, and can coordinate rotation with the spherical wall of inner chamber. Roller core shaft structure of the present invention is simple, rotates flexibly, and not easy to wear, long service life, has a good application prospect.
