INAImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]It is a widely used mechanical support。Its function is to ensure that the bearing has sufficient life conditions，To support the shaft and the parts on the shaft，And rotate relative to the frame、Oscillating motion，Minimize the friction between the rotating pairs，To obtain higher transmission efficiency。Commonly usedINAImported bearing[Imported bearing:Simply put, imported bearing agent refers to engaging in a certain imported bearing
Text combinationCAMApplication of software in high speed machining，Some considerations and typical problems in NC programming for high speed machining and their treatment in programming environment are described。The software environment involved in this paper is the intelligent CNC programming system developed by British Path Engineering Systems Company，EdgeCAM。The writer is in1998Began to engage in high-speed machining programming work，He wants to share his years of programming experience with everyone here。 High speed machining，Fast feed rate、The high spindle revolution is the phenomenon that everyone sees on the surface。The current mainstream of high-speed processing equipment
Process control of mold finishing Machining of mold parts，A general guideline is for different materials，Different shapes，Different technical requirements for adaptive processing，It has a certain degree of plasticity，Through the control of processing，Achieve good processing effect。 According to the appearance of the part shape is different，Parts can be roughly divided into three categories：Class of axes、Plates and special-shaped parts，Their common process is roughly：Rough finish——Heat treatment(quench、tempering)——finishing——electromachining——tongman(Surface treatment)——Combination processing。 Heat treatment of parts Heat treatment of parts
The principle of meshing transmission of cycloidal pin wheel with less tooth difference。Cycloidal pin wheel planetary transmission ensures constant transmission ratio，Number of pin teeth（The number of teeth of the needle wheel）The number of teeth different from the number of teeth of the cycloidal wheelZ2-Z1=1，The transmission ratio is：i13=W1/W3=Z/（Z1-Z2）=-Z1。The shortcomings of cycloidal pin wheel planetary reducer with small tooth difference：Boom 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
As everyone knows，Heat treatment is a process in which mechanical parts or products obtain the desired properties and ensure safe and reliable use by changing the material organization，It is an important part of mechanical manufacturing engineering。Because of the quality characteristics of heat treatment, the results can not be fully verified by subsequent inspections and tests，And once the heat treatment quality problems caused by the negative impact and economic losses are great，So in...GB／T19000In series standard，Heat treatment is recognized as“Special technology”，Special measures are needed，Implementation staff、comprehensive、Quality control of the whole process。Due to the domestic enterprises heat treatment equipment、Human element
Edge detection，Segmentation of the image，We use edge-based Image segmentation technology ，The technology is characterized by high efficiency，Image segmentation and edge detection are carried out simultaneously。How images are connected The heuristic search algorithm is adopted，Hough transform is used to obtain the best matching of edge fracture。In practice，Were on the split The minimum amount of information required to conduct the study，The practicability of the method is improved。The detection accuracy of edge detection technology is the difficulty in image processing，As a result of1)Complex marginal origin。(2)Both noise and edge are high frequency signals，Difficult to distinguish by frequency band，After smoothing and filtering, it appears as fuzzy，shadow
The process of making parts by precise forming，Also known as less chip processing。Traditional production processes ultimately apply cutting methods to produce parts with precise size and shape requirements，Billet quality during production30％The above becomes chips。This not only wastes a lot of materials and energy，And it takes up a lot of machine tools and manpower。Adopting precise forming process，The workpiece can become a mechanical part without or with only a small amount of cutting，Can greatly save materials、Equipment and manpower。The machining process with less cutting includes precision forging、stamping、Precision casting、Powder metallurgy、Pressure molding and injection molding of engineering plastics。type
INAbearing[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。]The disassembly should be carried out as carefully as the installation。Be careful not to damageINAbearing[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 are on the shaft
First up is the， Size limitation。usualIKOThe space in which bearings can be installed is limited。In most cases，Shaft diameter（OR-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。]Inside diameter）Is based on mechanical design or other design limitations。So bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”
