    摘要: The present invention achieves construction for a seal ring-equipped ball bearing (1a) that allows the outer-diameter dimension of a load-bearing surface (35a) to be made large, allows a large contact area with a transmission gear (16) to be secured, and allows dynamic torque to be reduced. Seal lips (14a) of seal rings (4a) that cover opening sections on both sides of the seal ring-equipped ball bearing (1a) have a substantially horizontal V-shaped cross-section and are configured so that an outer-diameter-side inclined section (25) and an inner-diameter-side inclined section (26) are connected by a continuous portion (27). The inner-circumferential edge section of the inner-diameter-side inclined section (26), which is the tip-end edge of the seal lip (14a), is made to slide over the entire circumference of the outer peripheral surfaces of both end sections of an inner ring (8a), the end sections being cylindrical surfaces (30) without seal grooves. The angle (α 1 ) of an inside-continuous surface (29) of the continuous portion (27) is at least 104°, and the overall length of the inner-diameter-side inclined section (26) is kept long by the continuous portion (27) entering radially inward into a wave-shaped retainer (10a).

    摘要: A bearing seal is provided which can be easily fitted into a seal groove formed in an outer race, and be kept firmly mounted to the outer race. First detent ribs (44) and second detent ribs (45) are formed on both surfaces of one side of a seal base plate (42) made of rubber and having the shape of a stripe. When one side of the seal base plate (42) is fitted into the seal groove (3) formed in the inner diameter surface of the outer race (1), the first and second detent ribs (44), (45) come into elastic contact with the side surfaces (3a, 3b) of the seal groove (3), respectively, so as to prevent the bearing seal from being pulled out of the seal groove (3). Thus, it is possible to keep the bearing seal stably mounted to the outer race.

    摘要: Construction of a rolling bearing with seal ring can be achieved in which, while securing the required seal performance, the rotation support portion can be made more compact by shortening the dimension in the axial direction of the installation space for an inner ring 3a, and torque can be lowered. A sliding contact edge 23 of a seal lip 12a that is provided around the inner-circumferential edge portion of a seal ring 5a on one end side in the axial direction comes in sliding contact with one end surface 24 of the inner ring 3a. The tip-end edge of a protruding portion 20 closely faces the surface of the inner ring 3a, forming a labyrinth seal 19 in this portion. With this construction, a stopper ring 17 for regulating the position in the axial direction of the inner ring 3a with respect to a shaft 15 is located so as not to protrude from the end surface in the axial direction of the rolling bearing 1a with seal ring. The problem can be solved because the diameter of the sliding contact portion is kept small.

    摘要: A ball bearing with seals on both sides is provided which is configured such that the pressure in the bearing interior is less likely to drop when a belt guide ring cools after it has been formed by resin molding, thus preventing the inwardly extending lip of each rubber seal from being pressed against the inner side surface of the seal groove. The belt guide ring (21) is formed on the radially outer surface of an outer race (2) of the bearing. Seal fitting grooves (8) are formed on the radially inner surface of the outer race (2) at its respective end portions. A rubber seal (10) has its radially outer portion fitted in each seal fitting groove (8). The rubber seal (10) has an inwardly extending lip (12) formed at its radially inner portion and having its tip elastically kept in contact with an inner side surface of one of two seal grooves (9) formed on the radially inner surface of an inner race (3) of the bearing, thereby sealing the bearing interior, and having an inwardly extending lip (12) having a tip which is kept in elastic contact with an inner side surface (9a) of the corresponding seal groove (9), thereby sealing the bearing interior. The contact surface of the inwardly extending seal lip (12) which is in elastic contact with the inner side surface (9a) of the seal groove (9) is formed with a recess (18) extending a limited circumferential range of the contact surface and defining a minute gap in cooperation with the inner side surface (9a) of the seal groove (9). With this arrangement, when the temperature and thus the pressure in the bearing interior rises when the belt guide ring (21) is formed by resin molding, the pressure is released to the exterior of the bearing through the gap defined by the recess (18). The pressure in the bearing interior is thus kept constant when the guide ring cools down after resin molding. This prevents the inwardly extending lip (12) from being pressed hard against the inner side surface (9a) of the seal groove (9) of the inner race (3).
