introduction：Needle roller bearing with inner ring and without inner ring difference IKONeedle roller bearings are roller bearings with cylindrical rollers，Relative to its diameter，The roller is thin and long。Depending on the occasion，Bearings without inner rings or needle roller and cage assemblies are available，At this time, the journal surface matched with the bearing and the surface of the housing hole are directly used as the inside of the bearing、Outer rolling surface，In order to ensure that the load capacity and operating performance are the same as that of the ring bearing，The hardness of the shaft or housing hole raceway surface，Machining accuracy and surface quality should be similar to the raceway of the bearing ring。Such bearings can only bear radial loads。

introduction：The main reasons for Siemens servo motor heating are: 1、overcurrent。Run with load due to prolonged exceeding rated current，The driver overcurrent protection value is set to exceed the rated value but lower than the current actual operating value and the driver does not alarm，Or disable overcurrent protection，The practical solution may be to find whether the motor bearing is normal，Whether the terminal of the three-phase power supply of the motor is securely connected，Whether the three-phase current is unbalanced，Whether the rotation direction of the motor changes too fast！

introduction：The principle of photoelectric speed sensor is shown in the figure，It consists mainly of light sources、condenser、Reflective transparent glass、Photosensitive tube and other components。The light beam produced by the light source is reflected through the transparent glass Onto the optical code disk，The optical code tray is installed on the rotating shaft of the measured speed。There are some on the surface of the optical code disk Radiant and spaced reflective surfaces and non-reflective fringes。So when the shaft rotates，The optical code disc emits an interval of reflected light onto a photodiode，Make the resistance value of the photodiode produce alternating changes。

introduction：TIMKENBearings are developed on the basis of rollingTIMKENbearing，itsTIMKENThe working principle of bearings is to replace sliding friction with rolling friction，Usually consists of two ferrule，The versatility of a group of rolling elements and a cage is very strong、standardization、Highly serialized mechanical base parts。Because various machines have different working conditions，Pair rollTIMKENbearingCapacity under load、Different requirements are put forward in terms of structure and performance。For this purpose，Rolling bearings require a variety of structures。however，The most basic structure is made up of inner rings、Outer ring、The rolling element and the cage are composed。
