1.Sign JB/T 3574-1997 of the rolling bearing Roll the basic content of sign on bearing products, should generally include bearing code and factory's code or trade mark Two parts, can also increase the factory and subscriber common other signs approved if necessary. Can't separate ing type bearing: Should stamp basic contents shown on the terminal surface of circles. In order to distinguish the terminal surface of basis, allow to stamp the symbol sign of the craft in one set of circles is not the terminal surface of basis. Separating bearing: Basic content that should stamp the sign on one set ...

5. The bearing height bearing height Limit the axial distance between the back of bearing two high washers of thrust. 6. Envelope enclose Washer Pour the angle size ring washer chamfer dimension Envelope enclose Washer Pour the surface of angle in the radial or axial extension part. 7. Pour the angle size radial chamfer dimension in radial Sets of circle or the intersection of imagination and sharp horn of washer get suits of circle or the intersection of washer and terminal surface and pour the intersection of horn and the intersection of surface and distance to pay space. 8. Pour ...

Section three Basic production process of the rolling bearing Because the difference in type, structural grades of pattern, person on a public errand, technical requirement, material and batch for the rolling bearing,etc., its basic production process is not all the same. First, processing courses of different major parts of the bearing: 1. The processing course of one set of circles: It is formal and different and different to some extent that bearing inner circle and processing of the outer lane depend on raw materials or blanks, among them the process before processing of car can be ...

The bearing has definite influence in bearing performance with the choice of the materials of the steel. One set of circles and rolling body of the rolling bearing, suffers high and exposed to the pressure repeatedly on one side, one side goes on in company with having rolling contact slipping. Person who keep, one side and sets of circle and both sides to roll body, or the intersection of and one party its slip and keep in touch, side suffer pulling force and contractile force. Therefore, to one set of circles of the bearing, roll the body and maintain the materials, performance, importance ...

Five. Size associated with public errand 1. Nominal the internal diameter ' External diameter noninal bore diameter outside diameter Wrap up, it holds in place with a net to be basically cylindrical inner hole ' Cylindrical outer surface Diameter of the round cylinder on the surface of theory. In a radial level appointed, wrap up the diameter of the cone of holding the surface of taper hole theory in place with a net. Wrap up the sphere diameter of the surface of theory of holding the basic spherical surface in place with a net. Note: As to the nominal external diameter of nominal ...

Six. Moment, load and life-span 1. Start the square starting torque of strength Make a bearing one set of circles or washers begin the moment required to rotate to another fixed sets of circles or washers. 2. Rotate the square running torque of strength When a bearing one set of circles or washers rotates, moments needed of preventing another set of circles or washers from moving. 3. Load radial load of the radial Act on the load of the vertical bearing axis thread direction. 4. Axial load axial load Act on the load of the parallel bearing axis thread direction. 5. Quiet load static load ...

1,The bearing and cooperation of the axle adopt the base hole system, the bearing and cooperation of the outer cover adopt the base axle system. Bearing dimensional tolerance and rotating the number value of the precision according to the regulation of GB 307- 84. 2,The journal cooperating with bearing and inner hole of bearing case are according to the regulation of GB 1031- 83, journal roughness Ra value is less than 1.6μ m, the inner hole roughness Ra value of the bearing case is less than 2.5μ m. 3,Last bearing sets of circle and roll on the period of the day from 11 p.m. to 1 a.m. ...

3 One set of circles of bearing 1.Inner circle Roll in one set of circles of bearing on the outer surface. 2.Outer lane Roll in one set of circles of bearing of a surface inclusive. 3.Inner circle of taper The taper rolls in the inner circle of the sub bearing. 4.Outer lane of the taper Taper roll sub outer lane of bearing. 5.Pair rolls in inner circle of a taper There is pair to roll the taper of one rolls in the inner circle of sub bearing. 6.Outer lane of a taper that pair rolls Have pair roll taper of dish get away sub bearing outer lane. 7.Wide inner circle The bearing inner circle ...

1 Bearing part introduction 1.Part of the bearing Make up one of every parts of the rolling bearing, but exclude all attachments. 2.One set of circles of bearing Have one or several roll line to the intersection of heart and annular part of rolling bearing. 3.Bearing washer Have one or several the intersection of thrust and annular part of rolling bearing to roll dish. 4.It is flat to block and enclose Can separate each basically washer when is flat,it last its inside or outside some until bearing outer lane or the eaches of inner circles sub block to rolling heart cylinder. 5.Oblique to ...

1,Round degree of axle and seat hole and blocks the verticality of the shoulder the requirement comes according to the corresponding precision of the bearing. 2,Should accurate calculation rotate whom suits of circle cooperate, cross person who full of, want accurate the intersection of calculation and fixed suits of suitable cooperation amount of lap too. It should obtain smaller to burn the full ofing amount too within the possible range to rotate one set of circles. So long as guarantee conscientiously the thermal expansion under the working temperature influences, and the centrifugal ...
