Identification, zero class bearing counterfeit bearings by

& emsp; & emsp; Increase the cost of materials: when using oxygen heating, heating uneven heating, spare parts will be installed to a half, not can't get down through the lift on the situation, such as coupler motor connection plate, appear such circumstance, can only be forced to scrap. Fast installation bearing to reserve position and fixed; , under normal circumstances, after just lubrication or lubrication bearing will have natural temperature rise and the last day or days. Due to the strength is too large, the teacher be afraid to use inside the ball cage with gearbox is damaged, so the teacher decided to pull down the fixed screw of the claw connected shock absorption to inside the ball cage set some larger space, and then tap. Gear speeder with gear transmission, some of the heat and noise is inevitable; But European products, don't like Japan and South Korea product need special downtime cooling time; 。 How on earth the problem appeared in where? When checking bearing cooling water bearing shell in conduit for ℃ temperature difference, the hub and bearing water temperature reached to go in and out. In with wheeled transmission machinery and equipment, both in driving wheel and driven wheel is working with wheel is given priority to, work with round the hole and shaft are connected, should be based on mutual cooperation to achieve the result of fixed condition. Scratch after seal seat to handle the rotation shaft bearing, if rotating bearing resistance and friction, mostly after seal cut journal, understands, and machinery used in the rolling bearing because of the low speed, and there is always load act on it, rarely appear skid phenomenon. This reduces surface and greatly reduce the service life of bearing, in the process of work, when the roller press bearing is the main power transmission parts, and machinery maintenance of the device. Mm, so that the ink roller transfer to the rubber roller printing ink was homogeneous, and reflected onto the plate printing roller has the same effect, printed products make people feast for the eyes, if not, will appear the phenomenon such as ink, ink way. It is to allow clearance or interference quantity, the change of shows, same as like the shaft basis; Plain surface, the average diameter of DMP tolerance zone, the upper deviation is zero ( Figure, equivalent radial load also affects the size of the outer ring of choice, - centripetal bearing ( Except for circular cone roller bearings) Accuracy is divided into Equivalent to GB/T. Investigate its reason, two kinds of generator is a big difference between oil and oil discharge way, after the death of former generator bearing, for the burning oil quantity is less, is not bearing the front-end of the generator to produce larger fire, to avoid such accidents. Precision heat treatment has two aspects: the meaning of heat treatment is according to the requirements of the parts to use, material, structure, size and the use of physical metallurgy knowledge and advanced computer simulation and testing technology, optimization of process parameters, to achieve the required performance or bring the potential of materials; The other aspect is fully guaranteed the stability of the optimization process, implement quality dispersion is small ( Or zero) And heat treatment distortion is zero.
