introduction： 1.Raceway sound The raceway sound is due toIKOWhen the bearing rotates, the rolling element rolls in the raceway and generates a smooth and continuous noise，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，Of high quality6203bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，It is used to reduce the coefficient of friction in the process of power transmission and maintain the center position of the shaft

introduction：FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]The generation of vibration in general，Rolling bearings themselves do not produce noise。Commonly felt“Bearing noise”In fact, the bearing directly or indirectly produces a sound effect of vibration with the surrounding structure。This is why many times the noise problem can be viewed as a vibration problem involving the entire bearing application。 （1）Excitation due to changes in the number of loaded rolling elements：When a radial load is loaded on somethingFAGbearing[FAGbearing:The main

introduction： Centrifugal separator for separating suspension components by centrifugal sedimentation。The suspension added to the drum forms a ring liquid layer under the action of centrifugal force(figure1 Sedimentation centrifuge diagram )﹐The solid particles in it settle to the drum wall﹐Sludge formation。The clarified liquid is discharged through the drum overflow port or suction pipe﹐Weighing fluid。The sediment is removed manually or mechanically at the end of the separation。Solid particles in the process of settling towards the drum wall﹐It also moves axially with the liquid flow﹐When the amount of feed is too large﹐Flow with the liquid to the overflow port﹐The fine particles that have not settled to the drum wall are discharged with the separation liquid﹐Make the separation liquid cloudy。Density of solid and liquid

introduction： one、Type selection In the building plumbing system，The valve serves to control the fluid。Because of the difference in structure and material，As a result, different valves are produced。 To ensure that the piping system can achieve the highest efficiency，Lowest cost and longest service life，The correct selection of valves is essential。 two、Feature Valves have four main functions： 1. Start and stop media flow 2. regulate（throttle）Dielectric flow

introduction：This paper mainly introduces the identification and quality inspection methods of some parts of medium speed flat sewing machine。 1.Needle plate and feed teeth The needle plate and feed teeth of the medium speed flat sewing machine are double rows,The back half has more force，When the operator does the reverse feeding operation on the sewing machine with the reverse feeding wrench，Its easy to get a shot。If there is injection phenomenon，The needle board fell down。If the quality of the needle plate is not easy to appear this phenomenon。Inspection method：Put the screwdriver into the feed groove on the needle plate，And shake from side to side，Carefully observe whether the force deformation，If deformed, it is inferior quality。 2.Press foot test method：You can clamp the press foot with pliers，see

introduction：Reduction ratio=Servomotor speed/Speed of output shaft of reducer Torsion calculation： For the life of the reducer,Torque calculation is very important,And pay attention to the maximum torque value of acceleration(TP),Whether it exceeds the maximum load torque of the reducer. The applicable power is usually the applicable power of the servo machine on the market,The applicability of the reducer is very high,The working coefficient can be maintained at1.2above,But in the selection can also be determined by their own needs: There are two main points: A.The output shaft diameter of the selected servo motor should not be greater than the maximum used shaft diameter on the table.
