Abstract
The utility model discloses a single-row full-complement full-locating sealing cylindrical roller bearing and belongs to the technical field of bearings. The bearing is composed of an outer ring, an inner ring, a roller, a loose rib and a spiral elastic sealing ring, wherein the inner ring is in an L shape, the outer ring is provided with a groove, the outer ring is connected with the loose rib and the inner ring through the spiral elastic sealing ring to form a cavity, and the roller is arranged inside the cavity. An outer protrusion of the groove of the outer ring is connected with one end of the loose rib, which is close to the outer ring, through the spiral elastic sealing ring in a sealing mode, and the outer protrusion of the groove of the outer ring is connected with one end of the inner ring, which is close to the outer ring, through the spiral elastic sealing ring in the sealing mode. By the aid of the unique spiral elastic sealing ring structure, the sealing effect of the bearing is guaranteed, so that the service life of the bearing is guaranteed, and the safety and the reliability of hoisting devices can be guaranteed.
Description
Technical field
The utility model relates to the full location of a kind of single-row full dress sealing cylinder roller bearing, and it belongs to technical field of bearings.
Background technique
Along with fields such as domestic and international harbour, mine, engineering machinery are fast-developing, the large-tonnage crane gear also develops rapidly, for adapting to the requirement of crane gear high-mechanic, high reliability, for its supporting lifting device bearing demand seems more and more important.At present, domestic lifting device self-contained bearing generally adopts open bearing, and the crane gear long-term work under field conditions (factors); Often receive the erosion of dust, rainwater,, also be difficult to guarantee the sealing of bearing though main process equipment also has seal arrangement; Often owing to seal unreliable causing, simultaneously, this series bearing also will guarantee high bearing capacity to the damage of bearings form; And can bear bi-directional axial load, and develop a kind of new structure for this reason, have the bearing of high-mechanic, full location, reliable sealing performance; Be the crane lifting matched with devices, be applied to fields such as truck crane, engineering machinery, become the task of top priority.
Summary of the invention
To above deficiency, the purpose of the utility model provides the full location of a kind of single-row full dress sealing cylinder roller bearing, with common NUP type open bearing, is designed with the structural type of sealing function, high-mechanic.
The technological scheme that the utility model adopted is the full location of an a kind of single-row full dress sealing cylinder roller bearing; Form by outer ring, inner ring, roller, loose rib and spiral elasticity seal ring; Inner ring is the L type; The outer ring has groove, and the outer ring is connected through the spiral elasticity seal ring with loose rib, inner ring, the built-in roller of the cavity of formation.The outer lug of said outer ring groove and loose rib are connected sealing near an end of outer ring through the spiral elasticity seal ring, and the outer lug of outer ring groove and inner ring are connected sealing near an end of outer ring through the spiral elasticity seal ring.
The beneficial effect of the utility model is: common NUP type roller bearing structure diagram, form no sealing configuration by outer ring, inner ring, roller, loose rib; The utility model changes common NUP type roller bearing inner ring rib, and the loose rib structure, and making bearing increase sealing becomes possibility; Unique spiral elasticity ring structure; Guarantee the sealing effect of bearing, thereby guaranteed the working life of bearing, and then guaranteed the safe and reliable of crane gear.Be widely used on the crane gear in fields such as harbour, mine, engineering machinery, runnability is good, and steady quality satisfies user's usage requirement fully.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, the outer ring, 2, inner ring, 3, roller, 4, loose rib, 5, the spiral elasticity seal ring.
Embodiment
As shown in Figure 1; The full location of a kind of single-row full dress of the utility model sealing cylinder roller bearing; Be made up of outer ring 1, inner ring 2, roller 3, loose rib 4 and spiral elasticity seal ring 5, inner ring 2 is the L type, and outer ring 1 has groove; Outer ring 1 is connected through spiral elasticity seal ring 5 with loose rib 4, inner ring 2, the built-in roller 3 of the cavity of formation.The outer lug of said outer ring 1 groove and loose rib 4 are connected sealing near an end of outer ring 1 through spiral elasticity seal ring 5, and the outer lug of outer ring 1 groove and inner ring 2 are connected sealing near an end of outer ring 1 through spiral elasticity seal ring 5.
Change common NUP type roller bearing inner ring rib, and the loose rib structure, making bearing increase sealing becomes possibility; Unique spiral elasticity ring structure; Guarantee the sealing effect of bearing, thereby guaranteed the working life of bearing, and then guaranteed the safe and reliable of crane gear.Be widely used on the crane gear in fields such as harbour, mine, engineering machinery, runnability is good, and steady quality satisfies user's usage requirement fully.
