Bundle boring machine bearing wear what should be done? No need to repair welding, brush plating, new methods to repair

Bundle boring machine equipment in operation, the rotor on both ends of the bearing support, one end is fixed bearing, one end being comfortable, thermal contraction. And at the time of the stop working this kind of equipment is the most common bearing wear, distance set of gear wear condition, in order to let you have more understanding of the situation, China bearing network on the basis of understanding, a good way to share out the repair. Many companies often maintenance master when encounter this situation, will use the way to stop the repair, such as repair welding, brush plating that actually also can form secondary injury of equipment, thus we find the reason in detail, measures for the maintenance of a more appropriate talents to bundle boring machine bearing wear better repair. Form bearing wear reason: analyze the thought formed after the cause of the bearing and distance set position wear for gear pressure plate and set loose casing pressure plate or lack of form the set set of prestressing force and distance shaft with relative motion and dynamic, incur trunnion wear. Bearing wear a better way to repair the bundle boring machine: according to this kind of transmission parts wear problem, traditional repair process is often after removal to repair welding repair workshop stop machining equipment disposal, down time is longer, and repair welding disposal is easy to form thermal stress from shaft bending deformation, formation of irreversible damage. And traditional brush plating treatment of common has the request to the coating thickness, cannot reach the thickness of the centimeter level. Other than no matter use what kind of repair technology can't boot operation conditions in the short term to complete equipment, thus the above several plans are clearly not the boring machine axis wear appropriate repair request. Against the axis wear condition, separation of several traditional repair process must be the scene of the use of polymer composite materials to repair plan. Polymer composite materials for bearing a wear problem can be based on the equipment parameters such as speed, bearing type, use the request to choose different equipment repair process, one of the most commonly used for mould repair process ( See image below) , the repair process application characteristics, separation field practice in processing repair tools, is the moulding method according to the positioning parts repair worn parts of a process at the site, a short time to repair, repair of high precision, low repair capital, no secondary damage to equipment, easy operation and other characteristics. Repair bundle boring machine bearings wearing the detailed steps of: 1, the position of the auxiliary repair process is mainly used in wear relatively average size, running speed is not high under the condition of equipment parts, in order to meet the normal operation of equipment; 2, the preparation work before construction, such as tools, information and need to change the spare parts ( The axial adjustment tools, oxygen - ring, remove device Acetylene gas cutting tools, micrometer, gasket, anhydrous ethanol, harmonic board) And so on; 3, repair, completes the personnel safe measures; 4, check the shaft end before remove the bearing wear conditions, wear and tear of the axial and radial relations are detailed measurement. Application of feeler gage to wear such as position to stop serious measurement, on the basis of the wear condition must repair plan; 5, on the basis of the axial and radial wear condition must be the orientation of the axial and radial auxiliary method, maximum limit to ensure alignment to ensure the use of fixed effects; 6, test and bearing, bearing inner ring at room temperature application specification size, after add anchor point to reach the bearing assembly requests; 7 and gas welding gun baked into the wear appearance of grease, carbide to Mars, grease. With sand or open tool to repair parts with metal nature, wash clean thoroughly with anhydrous ethanol. To ensure the appearance clean, dry, rough and hard; 8, bearing inner ring appearance after wash clean with anhydrous ethanol, brush release agent for standby; 9 and severe proportionally mixed 2211 f metal repair materials and stir until there is no color difference on average. The temperature low, want to use iodine tungsten lamp heating material, in order to reconcile. Reconcile the data to the harmonic board she into slices, and immediately daub, harmonic data should be used in 20 minutes after the end, prevent data curing. 10, using 2211 f metal repair data will wear position filled and slightly bigger than the wear volume. 11, and mold assembly, waiting for the data of curing; When the environment temperature 24 ℃ fully and reach the mechanical properties of not less than 24 hours, but every progress 11 ℃ temperature curing time by half. Pay attention to, not with open direct contact information, and the heating temperature beyond material shall be the highest temperature, don't let the data of temperature and substrate temperature difference is too large, rising and dropping drastically to prevent. Remove the bearing inspection after repair parts with and without defects, coating materials for fastening bearing again. 12, the taper bearings required quick hot charging bearings, prevent form the initial curing temperature and time affects the diameter size of the effect after repair. Wary of the bearing assembly process to control the bearing axial runout to prevent the formation of anchor point of damage. Bearing inner ring in the process of installation and repair of composition between bearing a compacted fill out and make sure they have redundant data. 13, on the basis of the bearing assembly process request fixed bearing, bearing in axial positioning. 14, the late application downtime when check in time in the process of pressure plate, found loose status timely. After the repair, once again proved that high polymer composite material collocation mould can very good processing equipment of transmission parts wear problem, proved that the use of polymer composite materials repair process has high repair precision, good meet the precision request of equipment, has the fixed asset is low, the repair time is short, no secondary damage to equipment, simple operation and other advantages.
