Analysis of deep groove ball bearing cage rivet Fracture

  Deep groove ball clutch bearing are bearing the most common type. Basic deep groove ball bearing is composed of an outer ring, an inner ring, a set of balls and a group holding structure into. Deep groove ball bearing type has two kinds of single and double row, single row deep groove ball bearing type code 6, double row deep groove ball bearing code is 4. Its structure is simple, easy to use, is the production of the most common, the most widely used class bearings.
Deep groove ball bearings usually consists of four main components parts, namely the inner sleeve, jacket, rolling element cage. The role of the cage is kept running deep groove ball bearing rolling elements in the correct position, bearing cage once the damage usually occurs as a whole will cause bearing failure. Sometimes due to cage breaking the rolling crushing, even bearing locking will cause accidents. Visible in the bearing retainer role can not be ignored. As the link rivet holder, it is a reliable operation of the protection cage, if broken will cause damage to the cage. Deep groove ball bearings delivered to customers after 300h, rivets cage fracture occurs, the customer will be returned to the manufacturer bearing failure analysis of its cage rivet fracture causes.
(1) deep groove ball bearings, coat ring and ball materials meet GB/T18254-2002 national standards set forth in GCr15 steel composition, heat treatment quality in line with JB1255 requirements.
(2) deep groove ball bearings work appear unusual axial vibration impact is caused by bearing failure and rivet fracture the root causes.
