Abstract
The utility model discloses a special bearing for a cold-rolled sheet supporting roller. The special bearing is mainly formed by assembling two outer rings, two inner rings, a middle spacer ring, two outer baffle rings, four groups of rolling bodies and four retaining frames, wherein annular oil grooves and a plurality of equidistantly distributed oil filling holes are formed in the middles of the two outer rings and the middle spacer ring; an oil nozzle is formed in each oil filling hole; a first annular groove is formed in the upper side wall of each oil nozzle; a first O-shaped seal ring is mounted in each first annular groove; second annular grooves are formed in the two sides of each annular oil groove in each outer ring respectively; a second O-shaped seal ring is mounted in each second annular groove; a first retaining frame gasket is mounted at one end of each supporting column of each retaining frame; a second retaining frame gasket is mounted at the other end of each supporting column of each retaining frame; and the first retaining frame gaskets and the second retaining frame gaskets are fixedly connected with the supporting columns respectively. The special bearing is easy to manufacture, low in cost, high in production efficiency, convenient to mount and dismount, high in rotary speed, good in reliability, long in service life and remarkable in social and economic benefits, and meets the need of low-carbon economy development.
Description
Technical field
The utility model relates to a kind of bearing, specifically the flat cold-rolled sheet support roll special bearing of a kind of highi degree of accuracy, high reliability.
Background technique
Be installed at present the bearing on highi degree of accuracy, high reliability flat cold-rolled sheet back-up roll, mostly be imported bearing, price is high, and there are a lot of deficiencys, as bearing bracket and a welding of retainer packing ring employing, other end is threaded, and this connecting means is in use easily snapped.And lubrication system flow of lubrication deficiency, bearing easily heats up, and affects the bearing reliability.In addition, bearing outer ring end face and inner ring end face, friction easily cracks relatively.
The model utility content
The purpose of this utility model, be to provide a kind of flat cold-rolled sheet support roll special bearing, and greasy property is good, and Safety performance is high, long service life.
The technological scheme adopted is:
A kind of flat cold-rolled sheet support roll special bearing, mainly by two outer rings, two inner rings, two outer back-up rings, spacer ring, four groups of rolling elements and four retainers are assembled in one, are known technology, it is characterized in that:
Two outer rings and middle spacer ring middle part offer respectively annular oil groove and a plurality of oil hole, in each oil hole, are equiped with oil nozzle, and the shape of oil nozzle and size adapt with oil hole, on the sidewall of oil nozzle upper end, annular groove are arranged, and are equiped with the O RunddichtringO in annular groove.Oil nozzle is made by ZCuZn40Pb2 brass, and the O RunddichtringO is nitrile butadiene rubber O RunddichtringO.In the bearing outer ring oil hole, the band oil nozzle, can effectively guarantee lubrication pressure, bearing inside obtained full and uniform lubricated, reduces bearing temperature rise, improves the bearing reliability, also saves lubricant oil simultaneously.
The retainer packing ring of each pillar two ends installing of retainer connects with corresponding cage pin solid welding respectively.(pillar of known bearing and retainer packing ring are a welding, and other end is threaded).Avoid easily snapping problem in large rolling load and large impact power lower supporting rod, guarantee bearing reliability and working life.
The retainer packing ring is circular arc nest (being the circular cone nest originally) with an intercolumniation welding nest, has increased the effective area of contact of welding, has improved weld strength, guarantees bearing reliability and working life.
Outer ring is lubricated offers respectively the seal ring annular groove with the annular oil groove both sides, is equiped with nitrile butadiene rubber O RunddichtringO in the seal ring annular groove.Bearing outer ring is lubricated guarantees the bearing lubrication oil pressure with annular oil groove both sides band O RunddichtringO, guarantees again lubrication flow, also can prevent that impurity from entering in bearing race with lubricant oil simultaneously, improves the bearing reliability, also saves lubricant oil simultaneously.
The utility model is easy to manufacture, and cost is low, and manufacturing efficiency is high, and economic environmental protection meets the low-carbon economy development need; Installation, convenient disassembly, speed capability is high, good reliability, long service life, social economic benefit are remarkable.
The utility model is a kind of FCDP138196750/HCC9YA6/P5 bearing, and bearing boundary dimension is φ 690X, φ 980X750, belongs to four-line column roller bearing.
The utlity model has following advantage:
1. adopt two welding manner (be a welding originally, other end is threaded) between shaft column and retainer packing ring, avoid easily snapping problem in large rolling load and large impact power lower supporting rod, guarantee bearing reliability and working life.
2. the retainer packing ring is circular arc nest (being the circular cone nest originally) with an intercolumniation welding nest, has increased the effective area of contact of welding, has improved weld strength, guarantees bearing reliability and working life.
3. bearing outer ring lubrication groove both sides band O type seal ring, guarantee the bearing lubrication oil pressure, guarantees again lubrication flow, also can prevent that impurity from entering in bearing race with lubricant oil simultaneously, improves the bearing reliability, also saves lubricant oil and environmental protection simultaneously.
4. band nozzle component in the bearing outer ring lubrication hole, can effectively guarantee lubrication pressure, bearing inside obtained full and uniform lubricated, reduces bearing temperature rise, improves the bearing reliability, also saves lubricant oil and environmental protection simultaneously.
