Abstract
The utility model relates to a pulley bearing, which comprises inner rings, an outer ring and rollers. The pulley bearing comprises two sets of inner rings and rollers, and the outer ring is integral. The pulley bearing has the innovation points that loose ribs are connected between the end surfaces of the inner rings and the outer ring; steel cable baffle rings are also inlaid between the loose ribs and the outer ring; the inner sides of the two inner rings are respectively provided with annular grooves; and coupling collars for fixedly connecting the two inner rings are buckled on the annular grooves. The utility model has the advantages that the common steel loose ribs are used as main seal, and therefore, the pulley bearing resists abrasion, and the steel cable baffle rings are inlaid between the outer ring and the loose ribs to take the strengthening effect. The two inner rings are connected and fixed by the coupling collars so that the structure of the pulley bearing is more stable and reliable.
Description
Technical field
The utility model relates to a kind of pulley bearings, comprises inside and outside circle and roller, and described inner ring and roller are two groups, and the outer ring is an integrated type.
Background technique
Pulley bearings is the full roller structure of biserial, can bear certain axial instantaneous load, is widely used in the industrial machinery of heavy-duty low-speed motion.The outer ring of tradition pulley bearings is an integrated type, and inner ring is made up of two unitary part, is provided with roller between each inner ring and the outer ring, and connects the dustproof rubber ring of using between the inside and outside circle of roller both sides.It exists shortcoming to be: the long-term back rubber ring that uses is easy to wear, and high-low temperature resistant is poor, and easily comes off after the wearing and tearing, causes inner lubricant grease contaminated.
The model utility content
The technical problems to be solved in the utility model provides good, the stable and reliable for performance pulley bearings of a kind of sealing property.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pulley bearings, comprise inside and outside circle and roller, and described inner ring and roller are two groups, and the outer ring is an integrated type; Its innovative point is: be connected with loose rib between the end face of described inside and outside circle, also be embedded with Steel Cable Baffle Ring between described loose rib and the outer ring; Described two inner ring inboards all have circular groove, and fastening on the described circular groove has the clasp that two inner rings are fixedly connected.
Advantage of the present utility model is: use common steel loose rib as main sealing, wear-resistant, Steel Cable Baffle Ring is entrenched between outer ring and the loose rib and plays reinforcement effect.Two inner rings are connected and fixed by clasp, make structure more reliable and more stable.
Description of drawings
Accompanying drawing uses the structural representation of novel pulley bearings for this.
Embodiment
As shown in drawings, the utility model relates to a kind of pulley bearings, and it comprises inner ring 1, outer ring 2, roller 3, loose rib 4, Steel Cable Baffle Ring 5, circular groove 6, clasp 7.
Above-mentioned inner ring 1 is two groups, places side by side, and its outer outer ring 2 that is with global formation all is covered with roller 3, and is marked with lubricant grease between every group of inner ring 1 and outer ring 2.Be connected with between described outer ring 2 both sides end faces and the inner ring 1 and prevent dust, and between loose rib 4 and outer ring 2, be embedded with reinforcing Steel Cable Baffle Ring 5 with loose rib 4.The inboard adjacent of two inner rings 1 all has circular groove 6, and fastening on the described circular groove 6 has the clasp 7 that two inner rings are connected as one, and makes structure more reliable and more stable.
