Without understanding this situation, excessive improvement in the accuracy of the mounting surface will increase the overall manufacturing cost。
one、NSKbearing[NSKbearing:Seiko Co., LTD(NSK LTD.)Be established in1916years,It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together,Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]Installation of: NSKbearing[NSKbearing:Seiko Co., LTD(NSK LTD.)Be established in19
Development history of heat treatment (1)Cleaning heat treatment Waste water from heat treatment production、Exhaust gas、Waste salt、dust、Noise and electromagnetic radiation will cause pollution to the environment。Solve the environmental pollution problem of heat treatment,Perform clean heat treatment(Or green heat treatment)It is one of the directions of the development of heat treatment technology in developed countries。To reduceSO2、CO、CO2、Dust and cinder discharge,The use of coal as fuel has been virtually eliminated,Less heavy oil is being used,Most have switched to light oil,Natural gas remains the most desirable fuel。 The waste heat utilization of combustion furnace has reached a high level
Heat treatment of die is an important process to ensure the performance of die。It has a direct impact on the following properties of the mold。 Mold manufacturing accuracy:The tissue transformation is not uniform、Incomplete and excessive residual stress caused by heat treatment cause mold processing after heat treatment、Deformation during assembly and mold use,Thus reducing the accuracy of the mold,Even scrap。 Strength of die:Heat treatment process is not properly formulated、The heat treatment operation is not standard or the heat treatment equipment is not in good condition,Causes the strength of the mold being treated(hardness)Not up to design requirements。 The working life of the mold:Structural disconformity caused by heat treatment
Rolling 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。]The ferrule and the rolling body,Repeatedly subjected to high contact pressure on one side,One side makes rolling contact accompanied by sliding。retainer,One side with the ferrule and both sides of the rolling body,Or one of them sliding contact,One side withstands tension and compression。therefore,For bearing rings,Roller and cage
FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]Whether the installation is correct,Affect the accuracy、Life span、property。therefore,Design and assembly department forFAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]The installation should be fully researched。It is expected to be installed according to operating standards。The operating standard items are usually as follows: (1)、cleanseF

Nowadays, the competition of enterprises is concentrated in the product style、New product development cycle and product production scale。Mold as a new product production of the key tooling,Its design and production are increasingly determining factors in the new product development cycle。In the automobile industry,The development cycle for new models used to be ten years,Now its two to three years,Ford and Toyota develop new models in just a year and a half,All this benefits from the improvement of the level of mold design and manufacturing。 With the development of NC machining equipment and high performance machining tool technology, high speed machining technology is becoming more and more mature,Greatly improve the mold processing speed,decrease
1、Finished 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。]Dimensions and rotation accuracy tolerances shall be metGB/T307.1、JB/T10336 And the relevant requirements of this Agreement。 2、Residual magnetic requirements should be metJB/T6641 Standard requirement 3、Bearing clearance requirements:We demand inspection
Some users have broken the output shaft of the drive motor after several months of operation of the equipment。Why did the reducer break the output shaft of the drive motor?For this purpose we looked at the output shaft cross section of the drive motor,It is found that the cross section of the output shaft of the reducer is almost exactly the same。The outer ring of the cross section is brighter,And the more toward the axis of the section color darker,It breaks at the end of the shaft!figure2Its a cross-sectional photo。This fully shows that the main reason for the broken shaft of the output shaft of the drive motor is that the motor and the reducer are assembled differently! When the concentricity between the motor and the reducer is guaranteed to be very good,Motor output bearing[bearing:
