Spherical bearing

Claim 2

A spherical bearing comprising: (a) an inner ball having an opening for receiving a shaft and a spherical outer surface; (b) a circular outer race having an inner surface that is complementary in shape with said spherical outer surface of said inner ball; (c) said circular outer race including a plurality of circumferentially spaced sections which extend around said inner ball snugly receiving said inner ball; and (d) a groove extending circumferentially around said race defining a thin wall portion, said thin wall portion being substantially less than 1/2 the thickness of said race, which permits flexing about said thin wall portion of the outer portions of the race relative to said ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of said ball.

Claim 3

The spherical bearing as set forth in claim 1 wherein said circular outer race includes three sections.

Claim 4

The spherical bearing as set forth in claim 2 further comprising a wire extending through said grooves around said race for securing said segments together.

Claim 5

The spherical bearing as set forth in claim 1 wherein a plurality of grooves extend circumferentially around said race of permitting flexing of the race relative to the ball.

Claim 6

A bearing assembly comprising: (a) an inner ball having an opening for receiving a shaft and a spherical outer surface; (b) a circular outer race having an inner surface that is complementary in shape with said spherical outer surface of said inner ball; (c) said circular outer race including a plurality of circumferentially spaced sections which extend around said inner ball snugly receiving said inner ball; (d) a groove extending circumferentially around said race defining a thin wall portion, said thin wall portion being substantially less than l/2 the thickness of said race, which permits flexing about said thin wall portion of the outer portions of the race relative to said ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of said ball; (e) a pillow block having a circular opening therein corresponding in shape with said race for carrying said race therein, an inner surface of said pillow block being chamfered; and (f) an outer surface of said race being chamfered for mating with said chamfered surface of said pillow block for preventing movement of said race within said pillow block.

Claim 7

A bearing assembly comprising: (a) an inner ball having an opening for receiving a shaft and a spherical outer surface; (b) a circular outer race having an inner surface that is complementary in shape with said spherical outer surface of said inner ball; (c) said circular outer race including a plurality of circumferentially spaced sections which extend around said inner ball snugly receiving said inner ball; (d) a groove extending circumferentially around said race defining a thin wall portion, said thin wall portion being substantially less than l/2 the thickness of said race, which permits flexing about said thin wall portion of the outer portions of the race relative to said ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of said ball; (e) a pillow block having a circular opening therein corresponding in shape with said race for carrying said race therein, an inner surface of said pillow block being chamfered; and (f) an outer surface of said race being chamfered for mating with said chamfered surface of said pillow block for preventing movement of said race within said pillow block.

Claim 8

A bearing assembly comprising: (a) an inner ball having an opening for receiving a shaft and a spherical outer surface; (b) a circular outer race having an inner surface that is complementary in shape with said spherical outer surface of said inner ball; (c) said circular outer race including a plurality of circumferentially spaced sections which extend around said inner ball snugly receiving said inner ball; (d) a groove extending circumferentially around said race defining a thin wall portion, said thin wall portin being substantially less than 1/2 the thickness of said race which permits flexing about said thin wall portion of the outer portions of the race relative to said ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of said ball; (e) a pillow block having a circular opening therein corresponding in shape with said race for carrying said race therein; and (f) spaced radially extending flanges provided on said pillow block for holding said race within said circular opening.

Claim 9

A bearing assembly comprising: (a) an inner ball having an opening for receiving a shaft and a spherical outer surface; (b) a circular outer race having an inner surface that is complementary in shape with said spherical outer surface of said inner ball; (c) said circular outer race including a plurality of circumferentially spaced sections which extend around said inner ball snugly receiving said inner ball; (d) a groove extending circumferentially around said race defining a thin wall portion, said thin wall portin being substantially less than 1/2 the thickness of said race which permits flexing about said thin wall portion of the outer portions of the race relative to said ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of said ball; (e) a pillow block having a circular opening therein corresponding in shape with said race for carrying said race therein; and (f) spaced radially extending flanges provided on said pillow block for holding said race within said circular opening.
