Definitions
- the present invention has a structure in which a conveyed object is directly received by a single ball that can rotate in all directions.
- the present invention relates to a pole bearing suitable for use in an article conveying device and the like.
- a transport device for transporting materials, parts, semi-finished products, products, and other articles at production plants, etc.
- ball bearings with a single ball that rotates freely in all directions and directly contacts the transported product also known as ball transfer
- a transport device is configured by arranging a large number of such items to smoothly transport the articles.
- This type of pole bearing is used for various other purposes.
- a large number of small balls are formed on the hemispherical concave surface 2a of the ball receiver 2 having the hemispherical concave surface 2a. 3 are arranged in a free manner, and one large ball 4 is placed thereon, and the large ball 4 is held so as to be rotatable in all directions.
- a structure housed in a casing 5 is generally used.
- the present invention provides a ball receiver having a hemispherical concave surface; a large number of small balls freely arranged on the hemispherical concave surface; A ball having an opening for projecting an upper portion of the large ball, and a casing for accommodating the ball receiver, the small ball, and the large ball.
- the ball is provided with a ball bearing including: a main ball for supporting a large ball which comes into contact with the large ball; and an auxiliary ball which is smaller than the main ball for supporting a large ball and does not contact the large ball.
- the present invention not only the main sphere contacting the large sphere but also the auxiliary small sphere smaller than the main sphere exists on the concave hemispherical surface of the ball receiver. It is not always the case that the contact occurs, and there may be cases where auxiliary balls intervene between the main balls. In that area, there is enough space around the main globules, so that the garbage that has entered inside collects in that space. Therefore, it is possible to prevent dust from adhering to the small ball and hindering the rotation of the small ball. In addition, it is possible to prevent the dust from directly adhering to the large sphere or intervening with the small sphere, thereby preventing the rotation of the large sphere. As a result, the performance of the ball bearing can be prevented from being reduced.
- dust may be rubbed and broken into small pieces by the main and auxiliary balls, but if a hole is drilled at the bottom of the ball receiver, the reduced dust can easily escape from the hole. Because it is discharged to the garbage, the garbage inside can be reduced. Also in this respect, the performance of the ball bearing can be prevented from deteriorating as much as possible.
- the ball receiver has a through hole for discharging dust at a lowermost portion thereof.
- the diameter of the auxiliary globules is preferably in the range of 0.6 D to 0.95 D, and 0.7 D to 0.9 D. More preferably, it is in the range of 85 D.
- the number of the main globules is N
- the number of the auxiliary globules is preferably in a range of 0.2 to 0.4 N, and is preferably in a range of 0.25 1 ⁇ to 0.4. More preferably, it is in the range of 35 N.
- FIG. 1 is a diagram showing a ball bearing according to one embodiment of the present invention divided into a front view and a cross-sectional view.
- FIG. 2 is a diagram for explaining the operation of the ball bearing of FIG. 1, and is an enlarged view of a main part of FIG.
- FIG. 3 is a diagram showing a conventional ball bearing divided into a front view and a sectional view.
- FIG. 1 is a diagram showing a ball bearing 11 of one embodiment of the present invention divided into a front view and a sectional view.
- FIG. 2 is an enlarged view of a main part of FIG.
- this ball bearing 11 is provided with a large number of main small balls 13 a and auxiliary small balls 13 on the hemispherical concave surface 12 a of the ball receiver 12 having a hemispherical concave surface 12 a.
- b is arranged freely.
- one large ball 14 is placed on top of it, and this large ball 14 is rotatably held in all directions, and a casing having an opening 15a for projecting the entire top of the large ball 14 is provided. It is a structure housed in 15. In addition, a hole 12b (through hole) for discharging dust is formed in the center, which is the lowest part of the ball receiver 12.
- Reference numeral 16 is a washer.
- main small balls 13a and the auxiliary small balls 13b are shown alternately in the figure, a large number of small balls are simply placed in the hemispherical concave surface Since the small balls are arranged by shining 4, the main small balls 13a and the auxiliary small balls 13b are not necessarily arranged alternately, but the main small balls 13a and the auxiliary small balls The sequence aspect of 13b is indeterminate. However, if the number of trapped small balls 13b is at least a certain ratio with respect to the number of main small balls 13a, an auxiliary is provided between the main small balls 13a and the main small balls 13a. It can be said that the rooster sequence in which the small balls 13b intervene appears.
- the hemisphere concave surface 1 2 a of the ball receiver 1 2 Is not only the main globule 13a that contacts the large globe 14, but also the auxiliary globules 13b that are smaller than this main globule 13a, as shown in FIG.
- the auxiliary ball 13 b may be interposed between the main ball 13 a.
- there is a sufficient gap around the main globule 13a so that dust (indicated by reference numeral 17) that enters inside collects in the gap. Therefore, it is possible to prevent dust from adhering to the main ball 13a and hindering rotation of the main ball 13a. Further, it is possible to prevent the dust from directly adhering to the large ball 14 or the dust being interposed between the large ball 14a and the rotation of the large ball 14 from being hindered. This can prevent the performance as a ball bearing from being reduced.
- the rotation direction of the two main globules 13 a in contact with the large globe 14 becomes the same direction, and the two main globules 13 a become the large globe 14 Makes a rotation that does not have the same force as the direction of rotation (does not hinder the rotation of the large ball 14). Therefore, it has a certain effect in that the rotation of the large ball 14 is performed smoothly.
- the diameter of the auxiliary small ball 13b with respect to the main small ball 13a can be set according to various conditions.
- the diameter of 13b is preferably in the range of 0.6 D to 0.95 D, and more preferably in the range of 0.7 D to 0.85 D.
- the ratio of the number of auxiliary globules 13 b to the number of main globules 13 a also depends on various conditions.
- the number of auxiliary globules 13 1 ⁇ is preferably in the range of 0.2 N to 0.4 N, where N is the number of main globules 13 a, and 0 More preferably, it is in the range of 0.25 ⁇ [to 0.35N.
- the ball bearing of the present invention can be used as a transfer device for transferring materials, parts, semi-finished products, products, and other articles in a production factory or the like.
