The preload method can effectively reduce the noiseListen to the sound and judge the motor bearing problem. Raceway sound The raceway sound is caused by the rolling elements rolling in the raceway when the bearing rotates, and a kind of smooth and continuous noise is excited. The preload method can effectively reduce the noise and reduce the radial clearance of the be...2021.06.16 03:28nmrbearing.com
Attention in mechanical structure design Increase the number of supporting bearings of the drive shaPay attention when using: eliminate the factors that cause the pump to overload, such as blockage of the flow passage; appropriately extend the start time of the pump, reduce the disturbance to the drive shaft, reduce the collision and friction between rotating parts and stationary parts, and the resultingFor water-lub...2021.05.26 02:06nmrbearing.com
A heat treatment process for metals and glassProcess: Reheat the quenched steel to a temperature below A1 for holding, and then cool (generally air cooling) to room temperature. Quenching, a heat treatment process for metals and glass. Annealing, normalizing, quenching, and tempering are the 'four fires' in the overall heat treatment. Isothermal annealing. I...2021.04.29 02:26nmrbearing.com
Different production lines use different types of clinker crushersThis article mainly summarizes the problems and solutions in the production process of the hammer crusher. In order to further reduce the impact load of the axial movement of the baffles at both ends of the hammer shaft, and prevent the hammer shaft from axial movement, the welding iron on the hammer plate can prevent ...2021.04.21 02:24nmrbearing.com
High bearing temperature is a common and harmful fault of rotating equipmentIf the cooler is not properly selected and the cooling effect is poor, and cannot meet the requirements of use, it should be replaced in time or a new cooler should be installed in parallel. Therefore, to quickly determine the cause of the failure and take appropriate measures to solve it is the guarantee for the conti...2021.03.22 03:38nmrbearing.com
