Abstract
The utility model discloses a hollow spherical gasket. The hollow spherical gasket is characterized in that the hollow spherical gasket is defined by a ring-shaped flat pipe body; the upper surface of the flat pipe body is provided with a spherical cambered surface to form an outer sphere of the spherical gasket; the lower surface of the flat pipe body is also provided with a spherical cambered surface to form an inner sphere of the spherical gasket; through holes communicated with the inner cavity of the flat pipe body are formed on the upper or lower surface or upper and lower surfaces of the flat pipe body; and the diameters of the through holes are not more than 0.5mm. The hollow spherical gasket can achieve self-lubrication, improve the lubricating property of the gasket contact surface, reduce the friction of the gasket contact surface and prolong the service life.
Description
Technical field
The utility model relates to a kind of pad, is specifically related to a kind of spherical pad.
Background technique
Spherical pad is the pad that a kind of both ends of the surface are sphere, spherical pad in some special occasions use, need guarantee has good lubricated assurance, but, present employed spherical pad, do not possess self-lubricating function, so can not guarantee good lubricating, the surface of contact of spherical pad is lubricated not ideal enough, surface of contact can produce bigger friction, so just causes pad than quick-wearing easily, and fricative in addition impurity is understood on a little end face that accumulates in pad, sphere contact to pad causes wearing and tearing and destroys the working life of shortening pad.
Summary of the invention
The purpose of this utility model is to be to provide a kind of selflubricating that realizes, improves the greasy property of pad surface of contact, reduces the friction of pad surface of contact, the hollow spherical pad that increases the service life.
The utility model is implemented by the following technical programs:
A kind of hollow spherical pad, it is characterized in that: surround by annular flat tube body, the upper surface of flat tube body has the outer spherical surface that spherical arc forms spherical pad, the lower surface of flat tube body also has the inner ball surface that spherical arc forms spherical pad, and the upper surface of flat tube body or lower surface or upper and lower surface are provided with the open-work that is communicated with the flat tube intracoelomic cavity.The diameter of described open-work is not more than 0.5mm.
The hollow spherical pad that the utility model provides, surround by the flat tube body, the inner chamber of flat tube body plays the effect of holding oil, make spherical pad can realize selflubricating, because spherical pad has been realized selflubricating, so can guarantee good lubricating, thereby improve the greasy property of pad surface of contact, reduce the friction of pad surface of contact; The inner chamber of flat tube body can store the fricative impurity of pad by open-work in addition, and impurity can not accumulated on the end face of pad, avoids the sphere contact of pad is caused wearing and tearing and destruction, thereby prolongs the working life of pad.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Come the utility model is described in detail below by specific embodiment:
As shown in the figure, a kind of hollow spherical pad of the present utility model, surround by annular flat tube body, the upper surface 1 of flat tube body has the outer spherical surface that spherical arc forms spherical pad, the lower surface 2 of flat tube body also has the inner ball surface that spherical arc forms spherical pad, the upper and lower surface of flat tube body is provided with the open-work 3 that is communicated with flat tube intracoelomic cavity 4, and the diameter of described open-work 3 is not more than 0.5mm.
Hollow spherical pad of the present utility model, the inner chamber of flat tube body play the effect of holding oil, make spherical pad can realize selflubricating, improve the greasy property of pad surface of contact, reduce the friction of pad surface of contact; The inner chamber of flat tube body can store the fricative impurity of pad by open-work in addition, and impurity can not accumulated on the end face of pad, avoids the sphere contact of pad is caused wearing and tearing and destruction, thereby prolongs the working life of pad.
