First, the appearance of special bearings for oscillation:
1) The diameter of the roll body is increased; the length of the roll body is increased.
2) Persist the frame to guide the roller by the outer ring rib; reduce the force on the roller.
3) Use the inner ring rib to guide the roller; improve the roller operation.
4) Cylindrical roller bearing retaining frame adopts integral layout; the strength is greatly improved.
5) The outer diameter of the aligning bearing is marked with oil groove oil hole; smooth effect is good.
Usually bearings:
1) The roller body diameter and the roll length are both small.
2) Adhere to the roller or inner ring guide.
3) Cylindrical roller bearing brackets use rivet layout; simply loose and cover.
4) The outer diameter of the aligning bearing has no oil groove oil hole; the smoothing effect is poor.
Second, select the special bearings for data oscillation:
1) The inner and outer rings and the rolling body are vacuum degassed bearing steel; the fatigue resistance is good.
2) The aluminum-iron-manganese bronze material is selected for the frame; the strength is high; the elasticity is good; the wear-resisting function is better.
Usually bearings:
1) The inner and outer rings and the rolling body are usually made of bearing steel.
2) adhere to the selection of zinc brass raw materials; low strength; poor elasticity.
Third, the heat treatment method oscillating special bearings:
1) The inner and outer rings are selected from Bay-Machine mixed quenching or Martens quenching + high temperature tempering; the hardness is uniform; the internal stress is 蝗 茫豢 茫豢 茫豢 寤骱 寤骱 寤骱 寤骱.
2) When working within 150C temperature; good stability.
Usually bearings:
The inner and outer rings are usually quenched; the resistance is poor; the impact resistance and oscillation function are poor; the thermal stability is not good.
4. Special bearings for public service and production process oscillation:
1) Strictly made according to P6 precision specification; special inner and outer diameter public service is very small.
2) The roll scales are different from each other ≤ 0. 0023. The outer diameter of the cylindrical roller has a convexity; the stress is prevented.
4) Super-fine treatment of tumbling appearance; high finish.
Usually bearings:
1) Usually PO level precision public service (some P6 level specifications) production.
2) Roller grouping ≤ 0. 005.
3) Cylindrical roller without convexity practice.
4) Some raceways are only polished; the finish is low.
5. Special bearings for internal clearance oscillation:
The clearance is produced according to the demand of the oscillating machinery; the scale control is on a small scale; the consistency is good.
Usually bearings:
The play is usually produced according to the specification group or the C3 group; the clearance or the 蚴 段 螅 螅 螅 肷 (12) source.
Sixth, the use of special bearings for oscillation:
Low noise; temperature rise. 榷ㄐ院茫皇褂 倜ぃ 倜ぃ 倜ぃ 缙谄 缙谄 窒 窒 @ drag 窒.
Usually bearings:
High noise; elevated temperature; poor stability; short service life; early fatigue appearance.
