Problems solved by technology

[0008] However, in the method of attaching the sealing member to the synthetic resin member by pressing, it is difficult to ensure the bonding strength of the sealing member, and it is difficult to continuously use the bearing for a long time without replacing parts.
In addition, if the dimensional accuracy of the sealing member or the synthetic resin member is low, curls and gaps may occur, causing foreign matter to enter the storage space. Therefore, high-precision processing is required, and it is difficult to reduce the manufacturing cost.

Abstract

The present invention provides a bearing tray that can be manufactured at low cost and can be used continuously for a long period of time without replacing parts, a manufacturing method thereof, and a bearing using the bearing tray. A bearing tray capable of forming an annular space between the bearing cover and the bearing cover by overlapping the bearing cover therewith, characterized by comprising: a disc member containing a thermoplastic resin; and a sealing member having at least a seal against the annular space A sealing portion that seals either one of the outer peripheral side and the inner peripheral side, and has a fitting structure, which is composed of a convex portion and a concave portion, and the convex portion is provided on either one of the sealing member and the disc member , the concave portion is provided on the other member and fits with the convex portion.

Description

technical field [0001] The present invention relates to a bearing tray (a shaft receiving dish), a manufacturing method thereof, and a bearing using the bearing tray. Background technique [0002] As a bearing that rotatably supports a rotating shaft or the like, a bearing in which a bearing cover is overlapped with a bearing tray to form a space between the bearing tray and the bearing cover, and a sliding member is arranged in the space is known. However, when such a bearing is placed in an environment with foreign matter such as dust, mud, powder, and metal shavings for a long period of time, the frictional resistance may increase due to foreign matter adhering to sliding parts, etc., thereby hindering the smooth rotation of the bearing. [0003] As a method of preventing such a problem, a technique of sealing a space in which a sliding member is accommodated with a sealing member or the like is known. For example, in Patent Document 1 and Patent Document 2, it is descri...
