Abstract
A ball support includes a cup having a passage formed through the cup and communicating with the chamber of the cup, and having a peripheral flange for attaching to an object. A rotary member and a number of balls are received and retained in the chamber of the cup. The cup includes an outer cut-off portion communicating with the chamber and the passage of the cup for allowing a cleaning agent to flow into the chamber of the cup to clean the ball support. The peripheral flange includes a recess communicating with the passage and the cut-off portion of the cup.
Description
- 1. Field of the Invention
- The present invention relates to a ball support, and more particularly to a ball support having a cleaning structure for cleaning the ball support.
- 2. Description of the Prior Art
- Various kinds of typical ball supports or ball units have been widely developed and used today. U.S. Pat. No. 4,696,583 to Gorges and U.S. Pat. No. 4,732,490 to Masciarelli disclose two of the typical ball supports and include a large ball and a number of small balls rotatably received in an enclosed housing which are enclosed for retaining the balls therein. U.S. Pat. No. 4,996,738 to Tifre disclose the other typical ball support also having a large ball and a number of small balls rotatably received in a housing. The housing includes an access hole formed therein for receiving a tool which may be used to disengage the large ball from the housing. However, the typical ball supports have no cleaning structure formed therein such that the ball supports may not be suitably cleaned. Dirt or the like may enter into the ball support and may damage the ball support if the ball support may not be suitably cleaned.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional ball supports.
- The primary objective of the present invention is to provide a ball support including a cleaning structure for cleaning the ball support and for maintaining the bearing effect of the ball support.
- In accordance with one aspect of the invention, there is provided a ball support comprising a cup including a peripheral portion having a peripheral flange laterally extended outward therefrom, and including a chamber formed therein, and including a passage formed through the cup and communicating with the chamber of the cup, and including an outer peripheral portion having a cut-off portion formed therein and communicating with the passage of the cup, a rotary member received in the chamber of the cup, a plurality of balls received in the chamber of the cup and engaged between the rotary member and the cup, and means for retaining the rotary member and the balls in the cup. The passage and the cut-off portion of the cup are communicating with the chamber of the cup for allowing a cleaning agent to flow into the chamber of the cup to clean the ball support.
- The peripheral flange of the cup includes a recess communicating with the passage and the cut-off portion of the cup.
- An object includes a cavity formed therein for receiving the cup, and includes a port communicating with the cavity thereof for receiving the cleaning agent and for allowing the cleaning agent to flow into the chamber of the cup via the passage and the cut-off portion of the cup.
- Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
- FIG. 1 is an exploded view of a ball support in accordance with the present invention;
- FIG. 2 is a cross sectional view of the ball support; and
- FIG. 3 is a cross sectional view illustrating the attachment of the ball support to an object.
- Referring to the drawings, and initially to FIGS. 1 and 2, a
ball support 30 in accordance with the present invention comprises acup 31 including a substantially semi-spherical shape and including aperipheral flange 301 extended laterally outward from the bottom peripheral portion of thecup 31. A rotary member, such as a cylindrical member or alarge ball 34 is rotatably received in thechamber 32 of thecup 31, and a number ofsmall balls 33 are also rotatably received in thechamber 32 of thecup 31 and engaged between thecup 31 and therotary member 34 for forming a ball bearing structure. - A
ring 35 is engaged on therotary member 34 and engaged with theballs 33. Acover 36 is secured to thecup 31 with fasteners 23 (FIG. 3) and includes anorifice 39 formed therein for receiving therotary member 34 and arranged for allowing therotary member 34 to be partially extended outward of thecover 36. Theorifice 39 of thecover 36 includes a diameter smaller than that of therotary member 34 such that therotary member 34 may be rotatably retained in thecup 31 by thecover 36. Thecup 31 and thecover 36 may be received in acavity 21 of an object 20 (FIG. 3), such as a working machine, a working table or the like, and may be secured to theobject 20 with thefasteners 23. - Referring next to FIG. 3 and again to FIG. 2, the
peripheral flange 301 of thecup 31 includes arecess 303 formed therein, and thecup 31 includes apassage 37 formed therein and formed through thecup 31 and communicating with or between thechamber 32 of thecup 31 and therecess 303 of theperipheral flange 301 of thecup 31. Thecup 31 includes a cut-offportion 38 formed therein and communicating with thepassage 37 of thecup 31 and therecess 303 of theperipheral flange 301 of thecup 31, for communicating thechamber 32 and thepassage 37 of thecup 31 with thecavity 21 of theobject 20. Theobject 20 includes aport 22 for coupling to a cleaning water or fluid or agent reservoir via ahose 24 or the like. - In operation, as shown in FIG. 3, the cleaning water or the cleaning detergent may be supplied into the
cavity 21 of theobject 20 via theport 22 and may be forced to flow through the cut-offportion 38 and thepassage 37 and thechamber 32 of thecup 31 and may thus be used to cleaning the interior of the ball support. The cleaning water or detergent may flow out through theorifice 39 of thecover 36. After the ball support is cleaned, the oil or grease may also be filled into the ball support via theport 22 and thecavity 21 of theobject 20 and the cut-offportion 38 and thepassage 37 and thechamber 32 of thecup 31 for lubricating the ball support. - Accordingly, the ball support in accordance with the present invention includes a cleaning structure for cleaning the ball support and for facilitating or maintaining the bearing effect of the ball support.
- Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
