Roller bearing parts by using two center hole positioning installation

Wafangdian bearing - Bearing - comfortable and durable On June 28, the authors explain for you: roller bearing parts by using two center hole location to install a: general with important cylindrical surface as a rough reference positioning, machining center hole, take the positioning precision of shaft center hole at the ends of the benchmark. Unified benchmark as far as possible do spherical roller bearing, datum coincidence, as the benchmark, and implement the installation processing multiple surface at a time. Center hole is workpiece machining unified benchmark locating datum and inspection, its quality is very important, its preparation is relatively complex, often with supporting shaft neck positioning, car ( Drill) The center cone hole. Again with central hole location, outside circle; Outside the circle positioning, coarse grinding taper hole; With central hole location, fine grinding cylindrical; Finally, supporting shaft neck cylindrical positioning, fine grinding, Blow grind or grinding) Cone hole, make the precision of the taper hole of the requirements. Roller bearing parts by using two center hole location 2: for the hollow axis and short axis of center hole location, available axis of the cylindrical surface positioning, clamping and torque. Generally USES three jaw chuck, four jaw chuck and other common fixture, or various kinds of high precision automatic centering special fixture, such as liquid plastic thin-wall centralizer, diaphragm chuck, etc. When machining cylindrical surface of the hollow shaft, commonly used with a central hole plug or rod spindle to install artifacts. Often used small taper hole plug; Large taper hole often used with a plug mandrel bar. At the same time bearing reminder note: clean the bearings, bearing a rough washing and fine washing, cleaning points can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil rotating thin-walled deep groove ball bearings, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly rotating bearings in the oil, must be carefully. Bearing comfortable and durable, )
