The method of extending the forklift disperser from the bearing life summary: Considering the statistical analysis of the mechanical reliability of the repair. The domestic CNC machine tool holder specification Mitsubishi Heavy Industries launched the large-scale gantry type five-face machining machine pressure welding skills, the new development of the differential shell inside the spherical surface CNC tool depicting the "Dalian machine tool representation" caused by the consideration of the trial of the round thread pile machine. The new mold forming skill processing has three holes of the part programming source program bearing failure guess and prevent the machining process system and the grinding and detection of the error aspheric lens Gear measuring machine related parameters tool compensation function new camshaft grinding analysis skill safety light curtain and switch--the method of the human body bearing bearing device used in mechanical safety and the clamping principle of disassembling the rapid speed clamp Small mobile wind turbine numerical control drilling machine--milling process life number method separate extension bearing gathering damage smooth overflow initiator machine extension forklift gatherer separately from bearing life method internal combustion forklift gatherer away from bearing operation frequent damage times forklift problem Share the driver's operation, protect the timely use of the bearing, and change the time to repair the new division. The skill level of the machine is to control the forklift. It is almost every case that the bearing is damaged or damaged. The parts are not far from the levers.
The method of extending the forklift disperser away from the bearing life is frequent; the number of damages is a large part of the forklift; if the driver is operating properly; the protection is timely; the bearing can be used for 3 months. Left and right; but also need to be replaced in the middle of repair. If the driver's skill level is low; the forklift that is being driven will be damaged from the bearing every month; other parts will be damaged after the damage; for example, the lever and the diffuser Sheets, etc.; then the material costs for equipment repairs have significantly improved.
Where is the cause of the loss of the collector from the bearing? In theory; although the driver is strictly required to give the oil every day to the bearing; this is not only cumbersome to operate; and the bearing is still often damaged. It is analyzed; because the high temperature of the initiator is transmitted to the bearing; in addition, the bearing also rotates at high speed; Under such conditions, it is difficult for the oil to remain in the bearing; the bearing is operated in a high temperature state; and the smooth condition is not good; this is the reason for the frequent damage.
Aligned with the above problems; it has also been experimentally placed in the smooth grease to heat; smooth grease penetrates into the bearing; after this treatment; smooth grease can fill the bearing; but because of the smooth grease layout after high temperature treatment; The effect of this method is not ambition; the service life of the bearing is not extended. We have also used the sharp-mouth grease gun to directly inject the butter from the bearing. Then we put it on the vehicle; after investigation and investigation; the service life of the bearing is greatly increased. Extends. This method of oiling has received a satisfactory effect; but the operation is more complicated. Then it is explored in the situation that the initiator does not collapse; the butter is added; the trial is successful on the 475 C-type initiator; the latter is in the 475C. And the 480, 492 type of trial on the machine; have received a very good role. After repeated theory, improvement; summed up the experience; the end formed a relatively simple oil filling operation; the detailed process is as follows:
(l) The oil injection method in which the initiator does not collapse firstly open the cover of the collector; observe the wear condition of the bearing; if it is recognized that the bearing is not damaged or the wear is not exceeded; then remove the collector pedal; adjust the connecting rod pin ; to leave the bearing and its seat back to the final position; use a grease gun to fill the hole in the bearing housing; until the bearing has oil spill; then slightly change the bearing; refill the oil; repeat the above work; until the bearing is around There is a small amount of butter overflowing; the bearing is changed again; the oil quantity is investigated; if there is resistance to the bearing change; the bearing is filled with butter. Then remove a small amount of butter that overflows from the bearing seat; remove the pin and the diffuser The cover is assembled from the head.
(2) The fuel injection method of the initiator crash will cause the initiator to crash to reveal the assembly of the bearing and the bearing housing; use a grease gun to grease the small oil hole below the inner ring of the bearing housing; the bearing will change the bearing when the butter overflows; There is butter overflow in one turn of the bearing.
After the above two methods are disposed of; the oil can not be refueled within half a year. This set of oil injection method is tested at Hengshui Railway Station; the mechanical integrity rate is significantly improved; significant economic benefits have been achieved. Material costs can be saved, and the loading and unloading capacity can be improved. Each unit can be loaded and unloaded by 30t per month. This method has also been implemented at other railway stations; both have achieved a more ambitious role.
