Bearing and gear repair what are the way you know

A 1, sliding bearing, bearing repair repair commonly used have integral sliding bearings and split two kinds. The repair of integral sliding bearing, the average with a change in the bush and after a boring, reaming, or fitter scraping method to repair, can also use plastic deformation which reduce bushing length diameter to repair. Split of the sliding bearing repair of thin wall bushing repair and repair two thick wall bushing. Thin wall bushing is often used in high speed, high movement precision request of the parts, such as a machine crankshaft main journal bearings and big end bearing, etc. When the thin wall bushing wear lighter, can be used to remove bearing the shim between the two convolution surface and press journal distribution method to repair. Change in thin wall bushing commonly used selection method. 025 - 5 mm, in order to assure cylindrical bushing and bearing hole wall stick close. Thick wall bushing is commonly used in medium and small construction machinery, can reduce the two bush involution flat gasket between the convolution surface to reduce the aperture or file, and then according to the journal stop skiving, make it to match the request. Hao machinery is the rotary plunger, titanium screw screw, machine tool spindle, the shaft processing, CNC lathe processing, the handle bar, chuck jaw for the company's flagship product, professional quality guarantee! Because professional, so excellent! 2, after repair of rolling bearings of rolling bearing wear and damage, rarely stop to repair, ordinary should switch to a new bearing the original model. But some conditions will also be able to stop repair: tapered roller bearing can be adjusted gland nut or increase ( Reduce) Gasket to reduce bearing clearance; When the bearing inner ring and shaft neck to cooperate or bearing outer ring and bearing hole with loose, usable electroplating solution of bearing outer ring or stop bearing hole repair, but electricity lost interchangeability. The use of the rolling bearing life and device correctly or not, reasonable use of it or not, and goes to have a close relationship. Second, the repair of the wheel gear reversing repair measures, insert, and changing the gear ring, plastic deformation and welding repair method, etc. A lot of gear is often a one-way transmission, thus form a lopsided wear. When the construction complete symmetry, flip 180 directly. After the device can be used. If asymmetry, can will first gear annealing, then cut asymmetric local, welded to the other side of the gear, and then to stop heat treatment of gear. Gear on little load and rotating speed is not high, when individual tooth was badly damaged, can put the bad tooth root ministry on a milling machine or planer processing out of the trapezoidal channel, and the gear blank to a certain degree of pressure into the groove and then welding or with pin fastening, with forming cutter finally finishing the right tooth on the milling machine. Change gear ring method, first gear annealing, car to all tooth, and make up a gear ring being connected, and then use welding or pin fastening, the last stop heat treatment. Plastic deformation method, the gear heated to 800 - After 900 ℃ in the teeth of the pressure, make its produce plastic deformation, the other parts of the metal extrusion to the tooth wear surface after plastic heat treatment. Light split parts with fine sand grinding of gear to the imperfect tired layer and after welding repair. Welding stoppage time should put the gear into the water, stop first hot back disposal, about steel carburized gear, 20 or 45 steel wire welding weld repairs are available, and can also fill with low hydrogen type electrode welding, welding repair after machining or manual model after finishing tooth shape, the final heat treatment again using abrasive refinement or use abrasive for research. Crack of gear rim, spokes, wheels available welding, riveting, adhesive to repair.
