Lathe spindle bearings: starter bearing a noise can be washed

In addition to the conventional overhaul cycle change bearing, a normal run time never failure, light, medium and heavy shall choose a ball bearing, bearing a column, the pole motor bearings should be placed on the shaft extension end. Maintenance costs, splash lubrication, rely on the fuel tank in the rotating parts of panting and splash up bearing lubricating oil supply, suitable for high speed bearing, low noise operation, the actual bearing lubrication state often to dynamic and static pressure, dynamic, extrusion, static, and dynamic, static, extruding mixed lubrication status form. Motor does not work, independent research and development of minxin shares currently have a number of varieties of powder metallurgy, and the institute of powder metallurgy, central south university cooperation, boost manufacturing precision power. Bearing gland cap too tight and must have a fixed gap between bearing outer ring, in order to protect the bearing of normal heat dissipation and axial channeling move, the gap between the end cover and the bearing seat gasket to adjust. Misuse of ac voltage to measure dc voltage, or the misuse of dc voltage to measure ac voltage, the display will show '', or low Numbers appear on the beat. To the bearing chamber parting surface cleaning, this is very trouble, also is very easy to overlook, operators use kerosene in bearing chamber completely parting surface cleaning time, not only can prevent the bearing chamber will not be against, and after cleaning, can put the bearing chamber was the remains of the release agent or other dirt jam exhaust slot through, is conducive to injection cavity gas discharge in the process of improving the quality of the product. Tank capacity should be and the size of the heated bearing and oil amount, if the container is too small, in continuous operation, into the bearing oil temperature will drop quickly, the effect is bad. When rotating too tight, Set set of tighten too far) ； Bearing noise ( The roller face or steel skid) ； Excessive axial thermal elongation ( Axial additional load bearing is statically indeterminate) ; Shoulder is too big, The bearing seal and friction) ； Holes of the block shoulder is too big, Send the bearing seal touch misrepresenting) ； Labyrinth seal gap is too small ( With the shaft friction) ； Lock washer tooth bending ( The bearings and friction) ； Left the position of the oil ring is not appropriate ( The flange cover and friction) ； On the ball or roller pressure pit ( Installed with a hammer bearing caused by) ； Bearing noise ( There are foreign source interference) ； Bearing and deformation (heated Use the spray heat sealed bearing caused by) ； Shaft is too coarse to make actual fit too tight ( Cause the bearing temperature too high or noise) ； Small diameter of hole, Cause high bearing temperature) ； Bearing hole diameter is too large. Deviation adjustment and coupling calculation conclusion table speed reducer is used for driving equipment of low speed high torque, the motor, internal combustion engine, or other high speed operating of power on the input shaft of the reducer gear of big gear on the output shaft gear mesh less to achieve the purpose of deceleration, ordinary there is few on the same principle of gear reducer and achieve ideal cut fruit, the size of the ratio of the number of teeth on the gears, transmission ratio. Fault has the following several ways: as a vibrator under heavy load start suddenly shut down due to production or other equipment failure, makes the screen box full of mineral aggregate, vibrator, such as in the case of heavy load again started easily to universal coupling vibrator and other damaged parts. Cage badly worn or loose rivet, countermeasures: improve housing material or processing steel bushing to squeeze into the hole, and then processing bushing hole to the correct size. Among them, the shape of the rolling element common has the ball, cylindrical and conical, such as the classification of rolling bearings rolling bearing according to the stress distribution can be divided into categories: centripetal ball bearings, mainly bear radial load.
