【 Jiaxing bearing common sense 】 The deformation of cylindrical roller bearing cage lock claw causes and solutions

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. 1, bearing retainer lock jaw fracture, crack, and the analysis of the causes of abnormal contact traces through the screening of retainer lock claw processing and analysis, confirm the cage lock claw crack, fracture, or pocket hole of abnormal contact has nothing to do with material performance factors, and with chopping claw, improper control of machining process pre splitting claw, punch Angle chosen unreasonable and punch stroke is infinite and other factors. 1) , improper control of pre split positions of pre split in the process of the claw are formed by milling cutter, milling cutter with the center line of the lock claw overlap, appeared deviation, lead to lock claw thickness have obvious differences on both sides, in the subsequent assembly broken claws on both sides of the lock claw inconsistent deformation, thin on one side of the large deformation and contact roller, roller in the working process of the collision with the lock point, produce crack or break. 2) Punch Angle chosen unreasonable usually cage after pre splitting claw, claw Angle between general 45 & deg; ~50° And cage assembly chopping claw punch Angle for 120 & deg; And the Angle difference between 70 & deg; ~75° Deformation, the Angle of the too big difference on the one hand make claw span too big too quickly make brittle material is easy to appear crack, deformation, on the other hand also easily lead to split claw and punch Angle of punch center appeared deviation, and make the split claw inconsistent deformation on both sides, appear asymmetric phenomenon. 3) In splitting claw uneven force, punch force inconsistent chopping claw processing are relying on experience by manual operator hammer to punch force f, make the lock claw at the top of the lock open on both sides to produce certain deformation roller. Deformation of lock claw shall not influence the bearing assembly, the operation does not produce interference of bearing, but if the operator in the process of splitting claw force is too large, punch into the lock claw completely contact with lock claw root, under the action of impact, cause a deformation of the lock claw root, thus promote the pocket hole beam area is deformation accordingly, appear uneven phenomenon, make the beams produces abnormal contact traces. 2, 1) solutions When pre splitting claws, to control the consistency of the milling cutter and the lock claw center, make sure both sides lock jaw position of symmetry and the thickness of consistency. 2) Reduce the punch Angle, will punch Angle by 120 & deg; Down to 90 & deg; To lock claw thicker cage can be respectively using 70 & deg; And 90 & deg; Angle of the punch to secondary splitting, in order to avoid too much deformation cracks or lock claw on the roller run interference. 3) Will be split claw hand percussion punch way instead of the fixed mold pneumatic way to punch force f, ensure that the size of the force application consistency, to control the stroke of the punch, avoid applying too ambassador lock claw in deformation, but also can ensure the quality of the lock point processing of consistency. 4) After splitting claw to lock claw Angle & theta; And thickness of S1, S2, S1, S2 thickness difference of the two is not greater than zero. 1 mm, shown in testing area; Also required by the fluorescent magnetic particle penetrating crack defects by way of checking the lock claw movable easily.
