Bearing clutch: nu bearing noise going on

Because in addition to the cost, also need to set of oil supply device, so the total cost is higher, and the production process requirement is high also, need our self-control, use and maintenance more troublesome. First for motor cast iron stand, with manual with good, if the first note on the aluminum rotor manual to cooperate, please add the o-ring on the outer ring, avoid run laps. Crawl under the static and dynamic friction coefficient, low speed, so as to protect the mechanical working accuracy, can reduce the mechanical vibration, reduce noise, to prevent pollution, improve working conditions. Defects, due to the main valve automatically the jamming are not locked, unit caused by overspeed accident: the first is the turbine last stage blade fracture damage, and breakdown of low pressure cylinder for the first time, strong vibration unit, string shaft, shaft stability damage, and damage the generator seal. Followed by hydrogen gas overflow occurs in the first time and caught fire, and turbine turbine oil ignition and part of the cable; , instability of shaft system improvement, destroy all bearings, twisting spindle, make each activity turbo-generator set some serious touch grinding, impact, seriously damage the unit. Clearance eligibility is greater than the group under heavy load bearing, bearing and shaft, with the shell hole bearing inner ring with the spindle rotation, outer ring is installed in the shell does not turn, also includes the thrust tapered roller bearings, thrust angular contact bearings, air conditioning compressor working loop evaporation area ( Low pressure area) And the cooling area ( High) 。 Open stamping outer ring needle roller bearing ( Image for the company to film, rustling figure will investigate) Needle roller bearing needle roller bearing is a cylindrical roller of roller bearings, relative to its diameter, roller is thin and long. Early bearing improper installation, improper installation will cause bearing damage, lead to bearing cost is greatly increased, and the bearing improper installation will cause bearing torque during rotation on, cause a fever. However, when the diameter of the bearing in the machine direction is restricted, choose needle roller bearing, special light and ultra light series of ball or roller bearings; When the bearing in the axial position of the machine is restricted, can choose a narrow, narrow range of ball or roller bearings. For root cause analysis, a lot of people think or say is simply to use environmental protection oil, the personage inside course of study all know any ships to enter the United States waters requires the use of environmentally friendly oil, if you don't pass this oil performance, so, why there is no such accidents occurred frequently on other ships? And focus on this single point support series of ship, this view is obviously difficult to set up. Prevent method to restore the bearing radial clearance, decrease interference, prevent method: according to the running time of the motor, the environment temperature, load conditions, factors such as a grease, determine its oil and oil change time. Meters, demolition of abrasive tool after curing, can use saw blade, polishing machine, file and sand paper discharging groove tools such as squeeze out excess material, never allow rap materials, the following Ms, the bearing can withstand one-way load, it is bigger than the axial bearing capacity of thrust ball bearing, and large rigidity, axial space is little. Oil bath lubrication is used for common and simple way of lubrication, applies: oil bath, Oiled) Lubrication method suitable for low or medium velocity, use common on low speed bearings.
