Carding machine for cotton roller bearing modification Abstract: FMS intelligent monitoring and control system development EDMMap software makes the tool more sharply threaded thread processing Introduction Industrial "advanced" boosts Shenyang machine tool skills across the EDM machining effect on the workpiece Four new products of the company limited to fill the domestic gap How to carry out numerical control education "Production and Research" AutoCAD skills in tunnel construction Pro/ENGINEER Wildfire version 3. 0 sheet metal parts depict milling, milling and milling machine mechanical CAD /CAM skills use to study the environmental conditions of machining sites Cimatron software post-disposal procedures and the use of slewing bearing device operating instructions industrial robots in automotive welding Beijing Zhengke Technology launched KW2-HS electric spindle type 2-axis continuous interpolation all-round view Grinding wheel product common sense International several kinds of new coordinate measuring machine products Mitsubishi Heavy Industries launched large gantry five-sided processing middle Kanedi CNC new K1000TII/MII advanced CNC system transformation bearing damage Rolla refueling found a strict guarantee equal to the car normal flat car often Encounter the severe appearance of the card bearing roller bearing The inner bearing replacement uniformity two-cycle replacement investigation found that the bearing is locked and will exhibit the kneading deformation. The strong mechanical effect is broken. The wear is severe. The inner tail presents an external needle grinding groove. The roller bearing damage increases the level of the labor force of the car. Analyze it.
In the normal flat car; we often encounter the appearance of the card holder to the cotton roller bearing and the inner cover lock or wear and tear. The replacement rate of the cotton roller inner sleeve and the bearing (94.35) is very high; According to the investigation, the bearing will be deformed due to kneading when the bearing is locked; the needle is broken or worn under the strong mechanical effect; a boss is present at the tail of the inner sleeve; The groove that the needle grinds. The damage to the bearing and the inner sleeve of the cotton roller not only increases the labor intensity of the flat car, but also adds the material cost of the machine.
After analysis, the boss that occurs in the wear is the real cause of the damage to the cotton roller bearing. In the work of the machine; wear is inevitable; when the inner sleeve occurs, the bearing will be supported. Severe kneading to make it damaged; once the frame is damaged; the needle will change in disorder; it is very simple to damage. It is also found in the flat car; the inner bosses hinder the disassembly of the bearing; it is difficult to refuel.
Align the above conditions; repeat the experiment; find that changing the bearing installation orientation can handle these problems. The specific method is: (1) firstly remove the end cap of the cotton roller bearing seat; turn the front part of the end cap to the turning; length Depending on the condition; about 5mm, (2) after installing the bearing on the end cap; knock the bearing back again; make it close to the end cap. At this time, the bearing is flush with the rear end of the inner sleeve; the needle is parallel to Inner sleeve appearance; needle roller wear will make it difficult to damage the bearing.
In production practice; we also found that this change can not only reduce the damage to the bearing; but also add the smoothness of the bearing. After the bearing orientation is moved; form an annular groove with the front end; the remaining oil will be added to the bearing Outflow; the groove at this moment just becomes an oil reservoir; in the bearing transition, the needle roller will be smoothed in succession; then the wear will fall.

Nickel-based alloy wire owns good resistance to high reactive gases, caustic resistance medium and acid corrosion performance, and also owns high strength, good capability of shaping, hot and cold forming and welding deformation. Therefore it is widely used in petroleum chemical industry, metallurgy, atomic energy, ocean development, aviation, aerospace to solve the problem that general industry, stainless steel and other metals, non-metallic materials engineering corrosion problems could not be solved,it is a very important kind of corrosion resistant metal materials. Nickel based alloys are nickel based alloys that contain alloy elements and which can be resistant to corrosion in a number of media. To classify the chemical composition characteristics, mainly nickel, nickel copper alloy, nickel alloy, nickel chromium molybdenum (Nie Mutie) (iron nickel alloy), nickel chromium molybdenum (including Ni Cr Mo alloy and Ni Cr Mo Cu alloy) and nickel iron chromium (both iron nickel alloy) and other types of. Pure nickel welding wire ERNi-1 for welding of 200, 201 nickel alloy and nickel plated steel plate; steel and nickel dissimilar materials welding; steel surface surfacing.
