Bearing stage: only have pressure bearing wheel

Friction noise is mainly caused by friction in the relaxation of the object vibration excited by the noise, when the vibration frequency and natural vibration frequency of the phase object at the same time, the friction will be big noise. UL for spindle for o with contact Angle of angular contact ball bearings, phenolic laminated tube straight hole solid cage, outer guide, bearing tolerance grade level, the inner and outer diameter tolerance, installed in pairs of universal structure, bearing in advance or a mild face-to-face installed back-to-back interference. Demolition of the corresponding thermal measuring point and its lead, lower bearing and shaft neck length of interface should achieve % above, and evenly distributed without deflection, contact Angle for - °. Bear radial load bearing radial sliding bearing, check the bearing level of intact to regular maintenance on the machine, shall carefully check the bearing in good condition. Outer raceway penal difference must be controlled in parallel, to avoid the damage caused by insulation bearing can avoid electric corrosion caused by the damage, so compared with the ordinary bearing used in motor can ensure more reliable operation. Ac commutator motor stepless speed regulating motor commutator working characteristic and the extruder performance close to, speed range, startability, the performance is more appropriate, prices are relatively low, so the original cold feed extruder, plastic extrusion machine, we adopt this way. Steel impurity content of impurities including non-metallic inclusions in steel and elements ( Acid soluble) Content, they often encourage each other to the harm of steel performance, such as oxygen content is higher, the more the oxide inclusions. Work environment cleanliness, group eccentric block quality difference, or group of eccentric block installation Angle error is bigger, cause vibration source center, fever caused by bearing, roller bearing instructions, installation, first level measurement basis level, such as uneven can be adjusted by means of plate on foundation. Real reason is the maintenance personnel change when bearing will lost on the gasket between the bearing seat, after such pressure on the cover, deformation of bearing outer ring is squashed, smaller radial clearance or almost zero, bearing denier heating operation, inflation will be blocked because of high temperature sharply and burn out, serious when running almost two hours bearing was burn out. On this basis for coaxial class has a lot of hair embryo tooling parts, lifting operation must be held by a qualified personnel, the hoisting command can only be held by a person ( To have the corresponding qualifications) 。 Ceramic bearing ring and roller adopts full ceramic materials, zirconium oxide ( ZrO silicon nitride ( SiN of silicon carbide ( 原文如此) Applying field, equipment, cryogenic engineering, optical instrument, high-speed machine, high-speed electric machinery, printing machinery, food processing machinery. Prices are turned over % above, a few layers of middlemen markups, to the buyer, after estimation can turn % above, buyers bear the price machine prices, product prices, how much Fried middlemen in the middle price, but we don't know.
