Abstract

A method of manufacturing bearing seal for use in a roller bearing is provided. A steel coil of a preselected width is fed into a ring rolling machine to form a closed coil ring. The closed coil ring is then welded along the butted joint. The welded closed coil ring is then fed to a series of pre-forming machines wherein the desired profiles of the final bearing seal are formed.

Claims (35)

1. A method of manufacturing a bearing seal comprising the steps of:

feeding a steel coil of a preselected width into a ring rolling machine,

cutting a divided length of the steel coil and

rolling the length of steel coil into a closed coil ring having a butted joint,

the butted joint of the closed coil ring is welded to form a welded steel coil ring,

transferring the welded steel coil ring to a weld bead removal station, then

transferring to a weld flattening machine

wherein any weld bead at the butted joint between the two cut ends of the steel coil ring is flattened to form a flattened steel coil ring,

transferring the flattened steel coil ring to a first pre-forming machine wherein a first profile is formed in the flattened steel coil ring to form a first profiled steel coil ring,

transferring the first profiled steel coil ring to a second pre-forming machine wherein a second profile is formed in the first profiled steel coil ring to form a second profiled steel coil ring, transferring the second profiled steel coil ring to a third pre-forming machine wherein a third profile is formed in the second profiled steel coil ring to form a third profiled steel coil ring,

and transferring the third profiled steel coil ring to a final forming machine wherein a final profile is formed in the third profiled steel coil ring to form a final profiled steel coil bearing seal, further comprising a step wherein the second profiled steel coil ring is transferred to a third pre-forming machine wherein a third profile is formed on the second profiled steel coil ring to form a third profiled steel coil ring prior to forming the first profile.

2. The method of claim 1

wherein the first profile formed in the flattened steel coil ring is formed at an angle of about 90°.

3. The method of claim 1

wherein the second profile formed in the first profiled steel coil ring is formed at an angle of about 90°.

4. The method of claim 1

wherein the final profiled steel coil bearing seal and the closed coil ring comprise eventually an identical amount of steel.

5. The method of claim 1

wherein the first profile forming the final profiled steel coil bearing seal results in a final profiled steel coil bearing seal ready to install as part of a complete bearing seal assembly.

6. A method of manufacturing a bearing seal comprising the steps of:

feeding a steel coil of a preselected width into a ring rolling machine,

cutting a desired length of the steel coil and rolling the length of steel coil into a closed coil ring having a butted joint, welding the butted joint to form a welded closed coil ring transferring the welded closed coil ring to a weld bead removal station, where excess weld bead is removed, transferring the welded closed coil ring to the weld bead. flattening station, where the weld bead is flattened;

transferring the welded closed coil ring to a first pre-forming machine wherein a first profile is formed in the welded closed coil ring to form a first profiled steel coil ring,

transferring the first profiled steel coil ring to a second pre-forming machines wherein a second profile is formed in the first profiled steel coil ring to form a second profiled steel coil ring, transferring the second profiled steel coil ring to a third pre-forming machine wherein a third profile is formed in the second profiled steel coil ring to form a third profiled steel coil ring,

and transferring the third profiled steel coil ring to a final forming machine wherein a final profile is formed in the third profiled steel coil ring to form a final profiled steel coil bearing seal, further comprising a step wherein the second profiled steel coil ring is transferred to a third pre-forming machine wherein a third profile is formed on the second profiled steel coil ring to form a third profiled steel coil ring prior to forming the first profile.

7. The method of claim 6

wherein the first profile formed in the welded steel coil ring is formed at an angle of about 90°.

8. The method of claim 6

wherein the second profile formed in the first profiled steel coil ring is formed at an angle of about 90°.

9. The method of claim 6

wherein the final profiled steel coil bearing seal and the closed coil ring comprise eventually an identical amount of steel.

10. The method of claim 6

wherein the first profile forming the final profiled steel coil bearing seal results in a final profiled steel coil bearing seal ready to install as part of a complete bearing seal assembly.

11. The method of claim 6

wherein the welded steel coil ring is transferred to a weld flattening machine wherein any weld bead at the butted joint of the welded steel coil may be flattened.
