Split bearing, high speed wire rod guide bearing optimization design and test

On the issue of the mechanical equipment noise, imbalance is due to the mechanical equipment operation, mechanical shaft concentricity deviation, the dimensional deviation between components or surface defects and the alternating mechanical force generated by the mutual collision and friction equipment sheet metal, bearings, gears and other moving parts vibration and radiation noise source called machinery noise. Maintenance and dismantling vibrator should pay attention to the following: when disassembling vibrator shall be conducted in a clean area; All parts must be cleaned before assembly, remove the burr; Tapping bearing inner and outer circle cannot be directly; All assembly surface coated with lubricating oil before assembly, such as lithium base grease; Carefully check the sealing ring, if you have aging or damage, change in time; Into the right amount of lubricating oil such as lithium base grease, etc. Assembly must be noticed when Y type sealing ring end face itself; All bolt fastening according to regulations, every fastening the next day at the beginning of installation, more times in a row, after check once every two days. If the bearing and shaft or cooperate with tight cover and sleeve bearing diameter ( Small tolerance) , strongly pressed when installation or install the bearing cover partial, will make bearing by external effect, the bearing due to the tight fever, affect the normal operation of the motor. And because the linear expansion coefficient of polymer is much bigger than steel, therefore, polymer bearings and steel shaft neck should be larger than the metal bearing clearance, clearance in addition, the strength of the polymer materials and the yield limit is lower, so when he worked in assembly and can withstand the load is limited. MHT bearing steel is added in the SAE, taper groove of automatic self-aligning ball bearing and spherical roller bearing under the help of shaft sleeve, also simplifies the installation program. For bearing is lubricated by lubricating oil, the oil should be added to the rules, companies contact outsourcing personnel understand the repair methods, no enterprise can give its cannot keep using traditional techniques to repair effect. ） ； Mobil half barrel; Angle grinder; Sand paper several; Flat to down size each; Torque wrench NM - NM） And with matching set of head; Of the instrument; The tooling/set; The tape measure; Connection with screwdriver, wire clamp, diagonal cutting pliers. Failure analysis of the phenomenon and reason of some iron and steel enterprise reducer bearing is a bearing fracture caused by bearing wear, trunnion, mm, bearing a mm, wear traditional repair mode and f the blue field repair technical analysis. And chrome steel is a common bearing material, as for the flange seal (in a way, you said on the aircraft engine is no good, want to use a, and the gap to stagger, under the high temperature of ℃, through enormous deformation and bearing load decreases, and cooperate with both sides blackened the yan LED headlight, very is to identify the degree of recognition. Results according to the test result of the optical and thermal pickling, bearing gasket material and heat treatment had no obvious abnormal quality, comply with relevant standards and technical requirements. Bearing the load distribution & amp; emsp; & emsp; Through MESYS shaft calculation module can be realized according to the standard DIN the whole shafting and the components of the bearing and deformation, strength calculation, at the same time also can analyze installed on multiple connection shaft bearing service life. Requires the aid of electric welding machine, keep the bearing and the surrounding environment clean even tiny dust into the bearing of invisible to the naked eye, also will increase the wear of bearings, vibration and noise.
