Abstract
The utility model relates to a sealed single range bearing of a cylindrical roller and includes an outer ring, an inner locking ring and a supporting frame; wherein, the middle of the outer wall on the outer ring is provided with a ring shape stress flute; the outer wall of the outer ring is provided with lock shape locking flutes; and the shape and size of the locking ring is matched with that of the lock type locking flutes that are internally provided with the locking ring. The ring surface on the inner side of the outer ring and the corresponding place on the stress flue are provided with a guide groove for the ring shape supporting frame. The utility model has the advantages of easy assembly, large bearing load, high limit rotating speed, strong reliability and long service life.
Description
(1) technical field:
The utility model belongs to a kind of bearing.
(2) background technique:
Bearing is one of parts the most frequently used in the modern manufacturing mechanism, and bearing is of a great variety at present, but its outer ring all is an integral type, and riveting has many rivets on the retainer, and not only assembling is inconvenient, and bearing load is little, limit speed is not high, influences working life.Equipment such as disintegrator that present mine is used and vibrating sieve are badly in need of the bearing of big load and high limit rotating speed, and existing bearing can't address that need.
(3) summary of the invention:
The technical problems to be solved in the utility model provide a kind of outer ring be split type, retainer is not established rivet, load is big, limit speed is high, the closely packed single row roller bearing of long service life.
The technical solution adopted in the utility model is:
The closely packed single row roller bearing comprises outer ring, inner ring and retainer.The centre of the outer wall of outer ring is provided with the belt stress groove, and a plurality of annular locking slots are arranged on the outer wall of outer ring, is equiped with clamp ring in the annular locking slot.Be provided with the annular retainer steering channel with the corresponding position of stress groove on the anchor ring of outer ring inwall.Retainer is made by the bronze material of no rivet, and be an overall structure, be equiped with a plurality of rollers on it, before the assembling with the cold punching method along the stress groove the outer ring dimidiation, the retainer that a plurality of rollers are housed is installed between outer ring and the inner ring, and the periphery of retainer is installed in the annular retainer steering channel.After assembling finishes, clamp ring is embedded in the annular locking slot, clamp ring and annular locking slot interference fit are with upper and lower two-part locking of outer ring.
The utility model is because whole processing is adopted in the outer ring, when assembling, the outer ring is washed into upper and lower two-part with the cold punching method along the stress groove, and after having assembled, bearing locks with clamp ring, this not only makes smooth, the smooth unanimity of the upper and lower two ones raceway in outer ring, the surface quality height, and easy to assembly, improved bearing load greatly, also improved limit speed simultaneously.In addition,, make to be doubled in working life of bearing manyly, and improved reliability, satisfy the needs of equipment such as the disintegrator used in the mine and vibrating sieve fully big load and high limit rotating speed bearing because retainer cancelled rivet.
(4) description of drawings:
Fig. 1 is a kind of embodiment's of the utility model a structural representation, and Fig. 2 is the structural representation of the utility model outer ring.Fig. 3 is the structural representation of retainer, and Fig. 4 is the plan view of Fig. 3.
(5) embodiment:
The closely packed single row roller bearing comprises outer ring 1, retainer 2, inner ring 3 and 5 clamp rings 5.The centre of 1 outer wall is provided with belt stress groove 4 in the outer ring, evenly be provided with 5 annular locking slots 6 on the outer wall of outer ring 1, the shape of clamp ring 5 and size adapt with the shape and the size of annular locking slot 6, on the anchor ring of outer ring 1 inwall, be provided with annular retainer steering channel 7 (consulting Fig. 2) with belt stress groove 4 corresponding positions, the integrative-structure (consulting Fig. 4) of the no rivet that retainer 2 is made by bronze material, a plurality of rollers 8 are housed on it, before the bearing assembling, along belt stress groove 4 outer ring 1 is washed into two halves with the cold punching method, the retainer 2 that a plurality of rollers are housed is installed between outer ring 1 and the inner ring 3, and the periphery of retainer 2 is installed in the annular retainer steering channel 7 of outer ring 1, after assembling finishes, 5 clamp rings 5 are embedded in respectively in 5 annular locking slots 6, two-part that outer ring 1 is washed open are locked (consulting Fig. 1) in aggregates.
Claims (1)
