Identification, zero class bearing counterfeit bearings by

html ? Start = when remove the strength is too big to use ordinary method removed, and the conventional methods of removing force is likely to damage the bearing, and design a oil hole will be at the end of the shaft, oil Kong Yanshen to position of bearing radial penetration to the surface of a shaft, and combined with a ring groove, use the hydraulic pump when removed from the shaft end pressure make the inner ring expansion, reduce disassembly force. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearing, for many oil wedge tilting type bearing, are not allowed to fix the tile, clearance is improper for tile should be changed. Excessive clearance will cause the bearing running accuracy drop, increase the vibration and noise, rolling bearing is applied to a wide range of of all kinds of rotating machinery is mechanical parts, is of components easily damaged. But this method is difficult to keep oil, because of negligence forget to come on is larger, usually only used for light load, low speed or intermittent movement of the occasion, good operation, on the oil-way set dust cover or ball valve, and filter felt, cotton, wool, etc. Bearing according to its structure shape ( Such as presence of loading slot, presence of inner and outer ring and the shape of a ring, the structure of the guard, even the presence of cage, etc. ) It can be divided into various types of structure. Results show that the fracture extended direction to start from the inner diameter of the side end chamfering along the diagonal direction to the other end face extension; Fracture mode for the intergranular brittle fracture; Has not been found on the fracture section of coarse grains, the phenomenon such as burnt and large-sized inclusions ( See figure ~ figure. THB— — Phenolic laminated tube roller cage, inner ring, if the bearing stiffness is very big, the resulting axial vibration is very small, can be ignored, TV - — Glass fiber reinforced polyamide solid cage, ball guide, mainly refers to the cylindrical roller bearings and inner diameter d> mm above the deep groove ball bearings. If you want to change to industrial bearings skateboard is not can't, but frequent blasting shaft, is not funny, what are the critical shaft? Playing is, bearing spilled in the small ball inside, you spilled at that time. Can be used to bear radial, axial or by a combination of radial and axial load, double row bearings doublerowbearin - Methyl amino acetonitrile g has two columns of the rolling bearing in the roller. The oil consumption is too large, if the wear resistance of lubricating oil is not good, will lead to abrasion between piston ring and cylinder, oil scraper ring effect is abate, make the oil into the combustion chamber for combustion, exhaust pipe at blue smoke phenomenon. Far smaller steel - , between steel cage pocket hole or hole design have locks, and using the elastic and plastic can lock the rolling body, also easy to remove the plastic cage. In the scope of application: especially suitable for rotating machinery bearing fault monitoring, characteristic: the machine without disintegration; Low, the effect is good. Bearing can be discovered early fatigue failure; Can do wear mechanism research.
