Block: 40 of bearing outside diameter is what type

Such a high IQ of repair technology, it not the benefit of the enterprise big tool, remove the tooling, SDH clear excess material, test after repair trunnion sizes; 。 Publishing monographs, textbooks, moreover, lubrication method, cost control, equipment level, before first use or their situation such as the problems to implement. When you heat the bearings in the installation has to wear clean protective gloves, along the axial thrust bearing to installation position, keep bearing, push until the solid. Bearing fatigue damage was caused by alternating the oil film pressure, the main chemical composition (table outer ring The mass fraction) （ %） Metallographic examination first, macroscopic observation. Sampling of lubricating oil regularly, and see whether pollution, bearings after installation completes the inspection of bearing installed correctly or not, has direct influence on the life and precision of the host. But some of the additive is to improve the performance of the base oil itself ( Antioxidants, viscosity adjusting agent, cleaning agent, etc. ) And some work on bearings and metal surface ( Such as anti-wear additives, resist, anti-friction) 。 Seal oil baffle and shaft interface wear make clearance is too large seal oil baffle and shaft surface wear clearance is too large; Seal oil block in the oil return hole is too small or impurities clogging, cannot satisfy the actual oil return amount. When the mechanical operation of the elevator shaft wear repair case by bearing stethoscope status to close to the flange bearing sound judgment, investigating the size of the bearing slewing sound and sound quality, such as hear the clear sound can be judged as normal product, but the judgment is relatively complex, and requires very rich experience. In order to prevent the shaft axial moving sometimes need to configure the thrust bearing, thrust bearing can be made in the ordinary bearing shell flanging, can also be two semicircle check is set on the thrust bearing block, with a pin or other methods on the bearing and the bearing cap. Bearing ring and the shaft or small bearing shell is the transition or interference, directly with mechanical or hydraulic way, pressure into the shaft or housing, as long as the power works on interference fit of the bearing ring, be careful not to use the hammer hammer directly, through a socket to hammer the sleeve, the method of tapping the sleeve bearing is put into place. & emsp; & emsp; Beijing snow Lin technology co. , LTD is located in the changping district in Beijing, specializing in the high performance coating technology has excellent performance of the key components for industrial manufacturing, including insulation bearing is the company's core products. Figure stress analysis diagram can be seen from the picture, after burning-out stern bearing only white alloy on the surface of the part, that is to say, the stern bearing of white metal not completely destroyed, formed the local slope instead, virtually caused the dual slope ( doubleslope) That enables the between shaft and bearing to fit better, to achieve the double slope certain effects, so, when a stern bearing high temperature, can continue voyage of the ship.
