introduction：The reducer is a power transmission mechanism，Speed converters using gears，Switch machine（motor）The number of turns slows down to the desired number of turns，And get a larger torque mechanism。The development of reducer in China has reached a considerable level，But with the international market changes，Many companies are also feeling the pressure，Many enterprises have changed the development history model，Seek a larger and more stable market as a major business growth point。 In the context of the global economic crisis，A number of original export reducer enterprises have turned to fight for domestic reducer market share，This will be the production of sales originally positioned in the domestic reducer

introduction： bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]It can be divided into different frictional properties according to the work of bearings：Plain bearings and rolling bearings。 Bearings that use the sliding motion of the shaft and bearing to bear the load are called plain bearings。According to the different oil film formation principles of the two relative moving surfaces of the sliding bearing。Divisible fluid

introduction：1. Illumination method On a fine day，Lift the lubricant with a screwdriver，With the horizontal plane45Degree Angle。Contrast sunlight，Observe the oil droplets，In the light，It is good to see clearly that there is no abrasive debris in the lubricating oil，Continuable action，If there are too many chips，Lubricating oil should be replaced。 2. Oil drop trace method Get a clean white filter paper，Drop several drops of oil onto the filter paper，After the oil leaks，If there is a black powder on the surface，It feels awkward to touch with the hand，It means that there are a lot of impurities in the lubricating oil，Good lubricating oil has no powder，Dry and smooth to the touch，And yellow marks。 3. Oil stream

introduction： The main goal of die roughing is to pursue the material removal rate per unit time，The geometric profile of the workpiece is prepared for semi-finishing。 During the cutting process, the metal area of the cutting layer changes，Causes the load borne by the tool to change，Make the cutting process unstable，Tool wear speed is not uniform，The quality of the machined surface decreases。Many are currently being developedCAMThe software keeps cutting conditions constant by the following measures，In order to obtain good processing quality。Constant cutting load。Constant cutting layer area and material removal rate were obtained by calculation，Keep the cutting load balanced with the tool wear rate，In order to improve
