High end manufacturing projects for bearing manufacturers require sufficient start-up funds and their minimum speed to achieve sufficient shutdown, ringing, and load operating rates. What are the important requirements for bearing usage? As a professional bearing manufacturer, Metalworking Bearings mainly lists two key requirements for customers.
The bearing cavity is not cleaned thoroughly or the grease added is not clean. For example, minor cleaning and wear inside the bearing cage, excessive tightness of the bearing seat hole, friction between the bearing seat and the raceway, causing a sharp increase in bearing temperature and burning.
The assembly quality of the bearing is poor, and the fit clearance between the shaft and the bearing seat hole is too small, which does not meet the requirements. If the quality of the bearing itself does not meet the requirements, or if too much lubricating grease is added, resulting in bearing damage.
The assembly flatness of the shaft and bearing seat holes, bearings, or rough or worn bearing chambers, as well as loose fit between the shaft and bearing sleeve.
The machining accuracy of the bearing end cover does not meet the requirements, or the bearing clearance is too small, the size of the machined parts is too large or too small, the installation of the bearing and bearing sleeve is too loose, and the fit between the bearing and bearing sleeve is too tight.
Reassembly of bearings requires high installation accuracy during installation. How to purchase ordinary motor brush processing.
Literally, there is a distinction in the power of the motor. For example, the motors of variable frequency air conditioners are usually used to increase energy conservation and reduce consumption (for example, for a child who uses them a lot).
A three-phase asynchronous motor is a collective term for driving one motor simultaneously. The power of the motor is determined in sequence by alternating current. The order is hierarchical. Alternating current is measured relative to two sets of coils.
The structure differentiation of three-phase asynchronous motors is composed of stator core, stator winding, rotor winding, and other parts. 1. Stator.
Three phase asynchronous motors should be stored in a dry and well ventilated place, and the temperature should be maintained between 60 ° C and+40 ° C. 2. Place in a dry warehouse. The temperature should be maintained at 5 ° C, the relative humidity should not exceed 80%, there should be no corrosive gas around, and the temperature should not be lower than 0 ° C. 3、 The motor of the rotor motor should be stored in a dry and well ventilated place. Compared with single-phase asynchronous motors, three-phase asynchronous motors have better operating performance and can save various materials. a. The three-phase asynchronous motor is made of electromechanical system (fan) actuator steel. The wind hood is a non explosion-proof structure, with an enclosure protection level of IP54 and equipped with an IP55 anti-corrosion layer. b. The rotor is made of aluminum cast or aluminum cast squirrel cage. The structure and installation types are IMB3, IMB5, and IMB35.
The insulation level of a 4-speed variable frequency motor is generally F, B, or F, and it adopts a damp heat belt type motor.
After installation, the measured bearing temperature is the lowest (the temperature of the user provided bearing is around 35 ° C). If the temperature exceeds the bed temperature+40 ° C, it is recommended to order and design separately.
