Large-scale bearing surface crackle reason analysis


27th September 2010 Bearing Technology 0 Comments
Summary: The superficial crackle of one set of circles is analyzed to importing in the large-scale bearing. The result indicates, the reason why the crackle produces and rubs and pare the craft improperly and relevantlying, it is burnt that the high-temperature flash back happens in the course of rubing and paring, make the fracture intensity of surface of material lower and produce the crackle. Keyword: Bearing; Crackle; Analyze One cold calender group of cold-rolled factory imports and supports the bearing of the roller, the external diameter of one set of circles inside ...

The quenching system designs to forge the steel ball automatically


27th September 2010 Bearing Technology 0 Comments
The broken ball mill has a good adaptability, can produce to the supplies continuously, production capacity is great, break it than the advantage such as being great, extensive adoption while crushing the course in the ore. Its principle is mainly utilized and forged mutual striking and friction between steel ball and ore to crush the ore, so it is essential to improve the wearability of the steel ball. The production process of the steel ball generally improves its superficial hardness and increases its wearability by forging and shaping, quenching the method to deal with. Quality of quality ...

The magnetism is played to France –Check the surface of the spare part and rub and pare the new method to burn


25th September 2010 Bearing Technology 0 Comments
In the machinery products, a lot of important spare parts such as bearing, gear, bent axle, camshaft, piston pin and universal joint,etc., need to pare processing after the heat treatment through rubing. By contrast, rub while paring the unit cuts the power consumption on the area to far exceed other preparation methods, the majority of the heat transformed will enter the surface of the work piece, so is apt to cause the change of processing the surface metallography and organizing. In a situation that it is improper to choose in technological parameter, cooling method and abradant state, the ...

” a perfect pair ” Dismantle the bearing ‘ [Fig. ]


25th September 2010 Bearing Technology 0 Comments
The main shaft of the gear box is led to the bearing and inlaid on the tip of bent axle ' Fig. 1 ,Because the working environment is not good, it is apt to get rusty. If you want to pull down the bearing, it is not a very easy thing. The general bearing dismantling device can't be used either. This is because the dismantling device of the bearing depends on two or three small claws to hook the bearing overcoat to dismantle the bearing, and the main shaft bearing can't dismantle after being fixed within the bent axle. Generally speaking, the maintenance personal often adopts the small bar of ...
