Deep groove ball bearings on the outer ring processing two grooves, and then add two aprons play what role?
The two aprons act as an oil seal.The bearing operation will have friction, will generate heat, causing damage to the bearing wear, reduce friction, ensure the normal life of the bearing, the bearing operation need lubrication, lubricating oil heating after thinning, if there is no oil seal oil blocking oil will flow away, so to install oil seal at the ends of the bearing.There are some bearing does not own seal, such as automobile gear box bearing, but some of them are soaked in oil in the oil pump work or keep hydraulic lubrication to them, so they do not need to seal. In addition, some machinery, such as parts of the motor, the ends of these motors are equipped with metal oil seals, and then the bearings do not need to bring their own oil seal.Another function of the oil seal is to block the outside debris into the bearing (track), such as sand, iron particles into the bearing track, it is easy to cause damage to bearings.
I can't make myself understood.The inner recesses of the outer race must be ball oriented.The outer ring is mainly used to cooperate with the external ring, when the General Assembly Design of the bearing outer ring is designed with shaft, theoretically will use the assembly slightly interference, so when the general assembly must heat the bearing seat, with hot charging way to smooth assembly.But the hot charge will be very troublesome, so in production, is not very strict for the general requirements of the bearing assembly, can be matched with a transition, but in order to ensure the bearing outer ring can not rotate in the bearing seat, give him added two ring for fixing.The groove was designed for rubber rings.
