Abstract
A mount construction for a bearing seal is capable of easily and surely installing the bearing seal in a bearing and, after installation, developing a stable seal performance by suppressing an extracting force. The bearing seal, formed by disposing an elastic member having a lip part on one side face of a reinforcement ring, is press-fitted into a ring body or radially reduced ring body in a state where the lip part is bent in a direction away from the outer peripheral edge of the reinforcement ring on the elastic member side of the bearing seal. While maintaining this state, the bearing seal is extruded from the inside of the ring body or the radially reduce ring into the bearing with care so that the lip part is not caught between the reinforcement ring and the bearing is installed on the bearing.
Claims15
A mounting arrangement for mounting a bearing seal, comprising:
- a bearing seal comprising:
- a reinforcing ring, and
- an elastic element disposed on one side of said reinforcing ring and having a lip projecting radially outwardly beyond an outer peripheral edge of said reinforcing ring;
- and
- a mounting ring having an inner diameter that is greater than an outer diameter of said reinforcing ring, said bearing seal being pressed into said mounting ring such that said lip of said elastic element is bent in an axial direction away from said outer peripheral edge of said reinforcing ring and on a side of said bearing seal at which said elastic element is located such that, when said mounting ring is brought into engagement with a bore of an outer race of a bearing with said lip bent in said direction away from said outer peripheral edge of said reinforcing ring and toward the inside of the bearing and the side of said bearing seal at which said elastic element is located directed toward the inside of the bearing, said bearing seal can be pushed out of said mounting ring in said direction away from said outer peripheral edge of said reinforcing ring and into the bearing so that said lip can be brought into engagement with a fitting groove on an outer race of the bearing.
A mounting arrangement for mounting a bearing seal, comprising:
- a bearing seal comprising:
- a reinforcing ring, and
- an elastic element disposed on one side of said reinforcing ring and having a lip projecting radially outwardly beyond an outer peripheral edge of said reinforcing ring;
- a bearing that includes an outer race having a fitting groove;
- a mounting ring having an inner diameter that is greater than an outer diameter of said reinforcing ring and no larger than a bore diameter of said outer race, said bearing seal being pressed into said mounting ring such that said lip of said elastic element is bent in an axial direction away from said outer peripheral edge of said reinforcing ring and on a side of said bearing seal at which said elastic element is located such that, when said mounting ring is brought into engagement with a bore of said outer race of said bearing with said lip bent in said direction away from said outer peripheral edge of said reinforcing ring and toward the inside of said bearing and the side of said bearing seal at which said elastic element is located directed toward the inside of the bearing, said bearing seal can be pushed out of said mounting ring in said direction away from said outer peripheral edge of said reinforcing ring and into said bearing so that said lip can be brought into engagement with said fitting groove on said outer race of said bearing.
