Abstract
The invention discloses a hub bearing for a farming machine. A left sealing ring and a right sealing ring are fixedly clamped between an outer ring and an inner ring. Lubricating grease is injected into a space formed by the outer ring and the inner ring between the left and right sealing rings. Two inner channels are formed on the outer ring, and a half waist-shaped channel is formed on the inner ring. Steel balls are densely clamped between the waist-shaped channel of the inner ring and the two inner channels of the outer ring. A ploughing blade mounting hole and an annular groove are formed on the right end face of the outer ring, and the right end face of the outer ring comprises a planar section end face and an inclined section end face. An O-shaped ring is elastically tensioned in the annular groove. An oil sealing component is arranged between the outer ring and the inner ring, and is pressed against the left sealing ring. The hub bearing is high in load bearing performance and waterproofness and long in service life.
Description
Technical field:
The present invention relates to technical field of bearings, the installation of using more specifically to a kind of agricultural ploughing machine hub bearing that blade is used that plows.
Background technique:
A kind of agricultural ploughing machine is arranged at present on the market; It is that the blade that plows is installed on hub bearing, and there is certain defective in this hub bearing in design, and mainly show: 1, its water-proof performance is relatively poor; After using a period of time; Because its working environment is more abominable, when plowing, often has water and be splashed on the hub bearing, thereby cause the hub bearing water inlet to scrap.2, the end face of its hub bearing is designed to a plane, makes the globule that splashes more be prone to get in the hub bearing.3, its load-bearing property is relatively poor, in the agricultural ploughing machine working procedure, because the environment that plows is comparatively complicated, the bearing of hub bearing is had relatively high expectations.
Summary of the invention:
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of agricultural ploughing machine to use hub bearing, its load-bearing property is good, and water-proof performance is good, long service life.
The scheme that the present invention solve the technical problem is:
A kind of agricultural ploughing machine is used hub bearing; Comprise outer ring, inner ring and steel ball; Blocking is fixed with left seal ring and right seal ring between outer ring and the inner ring, is injected with lubricant grease in the space that outer ring between left seal ring and right seal ring and inner ring are constituted, and forms two interior raceway grooves on the outer ring; Form waist shape raceway groove on the inner ring half, steel ball is covered with between two interior raceway grooves of the waist shape raceway groove that is clamped in inner ring and outer ring;
Form plow blade mounting hole and annular groove on the right side of outer ring, the right side of outer ring is shaped to planar section end face and bevel phase end face, and 0 type circle elastic tension is in annular groove; Oil sealing assembly is installed between outer ring and the inner ring and is pressed against on the left seal ring.
Said Oil sealing assembly is made up of first Oil sealing assembly and second Oil sealing assembly; The first Oil sealing assembly lip elasticity of first Oil sealing assembly is pressed on second Oil sealing assembly; The second Oil sealing assembly lip elasticity of second Oil sealing assembly is pressed on first Oil sealing assembly; Form step on the first Oil sealing assembly body of the bottom of the second Oil sealing assembly lip and the first Oil sealing assembly contacting point, fill with grease between first Oil sealing assembly and second Oil sealing assembly.
Outstanding effect of the present invention is: 1, its adopts two row's steel balls to be covered with to be arranged on inner ring and the outer ring, so its load-bearing property is good.
2, it has the bevel phase end face, helps in the course of the work that the globule flies out from this bevel phase after being splashed to the present invention, can not get into hub bearing, thereby alleviates the pressure of right seal ring water inlet.
3, its O type circle helps anti-sealing from anterior entering the of the present invention, and it can reduce the chance that the globule that splashes contacts with right seal ring.
4, its Oil sealing assembly good seal performance.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is the enlarged view at Oil sealing assembly place among Fig. 1
Among the figure: 1, outer ring; 11, interior raceway groove; 12, the blade mounting hole that plows; 13, annular groove; 14, bevel phase end face; 15, planar section end face; 2, inner ring; 21, waist shape raceway groove; 3, steel ball; 4, left seal ring; 5, right seal ring; 6, O type circle; 7, Oil sealing assembly; 71, first Oil sealing assembly; 72, second Oil sealing assembly; 71a, the first Oil sealing assembly lip; 71b, step; 72a, the second Oil sealing assembly lip.
Embodiment:
Embodiment sees that like Fig. 1, shown in 2, a kind of agricultural ploughing machine is used hub bearing; Comprise outer ring 1, inner ring 2 and steel ball 3; Blocking is fixed with left seal ring 4 and right seal ring 5 between outer ring 1 and the inner ring 2, is injected with lubricant grease in the space that outer ring 1 between left seal ring 4 and right seal ring 5 and inner ring 2 are constituted, and forms two interior raceway grooves 11 on the outer ring 1; Form waist shape raceway groove 21 on the inner ring 2 half, steel ball 3 is covered with between two interior raceway grooves 11 of the waist shape raceway groove 21 that is clamped in inner ring 2 and outer ring 1;
Form plow blade mounting hole 12 and annular groove 13 on the right side of outer ring 1, the right side of outer ring 1 is shaped to planar section end face 15 and bevel phase end face 14,0 type circles 6 elastic tensions in annular groove 13; Oil sealing assembly 7 is installed between outer ring 1 and the inner ring 2 and is pressed against on the left seal ring 4.
Said Oil sealing assembly 7 is made up of first Oil sealing assembly 71 and second Oil sealing assembly 72; The first Oil sealing assembly lip 71a elasticity of first Oil sealing assembly 71 is pressed on second Oil sealing assembly 72; The second Oil sealing assembly lip 72a elasticity of second Oil sealing assembly 72 is pressed on first Oil sealing assembly 71; Form step 71b on first Oil sealing assembly, 71 bodies of the bottom of the second Oil sealing assembly lip 72a and first Oil sealing assembly, 71 contacting points, fill with grease between first Oil sealing assembly 71 and second Oil sealing assembly 72.
Working principle: form two interior raceway grooves 11 on the outer ring 1, form waist shape raceway groove 21 on the inner ring 2 half, steel ball 3 is covered with between two interior raceway grooves 11 of the waist shape raceway groove 21 that is clamped in inner ring 2 and outer ring 1; Its adopts two row's steel balls to be covered with to be arranged on inner ring and the outer ring like this, so its load-bearing property is good.
