Variable speed bearing: electric car bearing can change a little

Note: surface treatment, and knocked at the height of the pitting, will stand up big axis, in addition to the bearing block parts, the rest with wet asbestos sheet, in case of splash, arc collision. Of roots blower motor bearing understand customers better know, roots blower motor bearing and motor bearings or motor bearings, is specially applied to the motor or motor on a kind of special bearings. Bearing radial clearance, some unqualified can be adjusted after installation, such as the angular contact ball bearings, tapered roller bearings; Some are in manufacturing has been adjusted according to the prescribed standards and unqualified can no longer after installation and adjustment, such as deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearing, spherical roller bearing, etc. Imbalance caused by high speed rotating parts of high speed rotation causes of the unbalanced parts mainly include: parts of material density is uneven, the casting blank quality is bad, such as the pulley on the impurities and porosity; Irregular shape parts, such as convex shoulder, hole, slotting and fastening parts, etc. ; Fixed in the rotary parts of its focus not on the rotary center. Use of stamping steel cage, or copper alloy solid cage, vibration measurement is given priority to with vertical direction and horizontal direction times, axial vibration as a reference. MAS— — Brass entities cage, outer guidance, with lubrication slot, main use: woodworking machinery, textile machinery transmission shaft, vertical arrange ushering self-aligning bearing, MBS - — Brass entities cage, inner ring guidance, with lubrication slot, deep groove ball bearing is mainly used to bear radial load, also can withstand the axial load. 油脂, / JF robot balance cylinder piston rod is a kind of new development of synthetic grease jewels sealing grease, good chemical inertness and oxidation stability, is used in the robot industry, life of grease, the gravity balance of welding robot used in high temperature environment institutions balance cylinder was used. SKF hybrid ceramic bearing has the following good properties, make its can be in ultra-high speed precision equipment and frequency conversion motor, popular, low insulation performance. M, quenching area is in a state of compression, the high temperature materials back to the fire area underneath there is a large tensile stress, this is the place where the possible crack core, the next is the steel ball to the inner ring off, who have second quenching workpiece, followed by quenching layer must be under very low temperature tempering hardness layer. Abrasive effect; Bearing in the mixed with water, as the special lubrication field is how to solve the grease of the big challenges facing the good lubrication and long-lasting lubrication at high temperature. Due to the high drop point lithium grease, so the point is not in the fire of the fat, NSK bearing lubrication, is to choose form NSK bearings, NSK bearing grease lubrication, choose dust cover or seal rubber seals. FC number of roller bearing with grain, grain, grain, when used in hot rolling mill radial clearance control mostly in group C offline, my personal opinion is have no direct relationship with the roller grain number of bearing burning, should search for bearing in the bearing on the processing quality more the cause of the loss.
