INAStainless steel 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 phenomenon that the size or shape of a member changes due to force is called deformation。The mechanical equipment in the production site is in bad condition due to the working condition,Often overloaded operation,Deformation of some bearings is very common。Their change

The advantages of single-board electromagnetic clutch are as follows: 1、High speed response Because it is a formula class so the torque transfer is very fast,Convenient movements can be achieved。 2、High durability Good heat dissipation,And they use high-grade materials,Even at high frequencies,High energy use,Also very durable。 3、assemble、Easy maintenance Ball bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is fixed and reduced during mechanical transmission
Stainless steel has a variety of surface processing to broaden its application field--Different surface processing makes the surface of stainless steel different,Make it unique in the application。 In the field of architectural applications,The surface processing of stainless steel is important for many reasons。 Corrosion environments require smooth surfaces because smooth surfaces are less prone to fouling。The deposition of dirt will cause rust and even corrosion of stainless steel。 In the spacious hall,Stainless steel is the most commonly used material for elevator decorative panels,The handprints on the surface can be erased, though,But it affects the beauty,So it is best to choose a suitable surface to prevent fingerprints。 Sanitary conditions for many
⑹.Innovative design of internal structure of cylinder beam; Early electrohydraulic hammer power heads were connected by a seamless tube from the main operating valve to the secondary valve seat,End weld。The tube is subjected to alternating loads during operation,The tube is loaded when the hammer head returns,The pipe is unloaded when the hammer strikes,Round and round,Therefore, for the hammer with bad working conditions, there will be pipe breakage and weld cracking。 Because this tube is inside the box with the cylinder beam,In case of failure,Hard to repair,Even repair is difficult to guarantee quality,So it becomes a big hidden danger,It is also the main factor affecting the life of the power head。To solve this problem,

The internal stress of metal during heating can be divided into thermal stress and structural stress。 1、Thermal stress Blank in the heating process,Temperature differences occur because the surface temperature is higher than the center temperature,Causes uneven expansion of the outer layer and the heart,The resulting stress is thermal stress。The magnitude of thermal stress and the properties of metals、temperature-dependent。The cut-off temperature depends on the temperature conductivity of the metal、Section size and heating rate。If the temperature conductivity of the metal is poor、Large section size、Fast heating speed,The cross section temperature difference is large,Therefore, the thermal stress is also high。conversely,The thermal stress is small。If the thermal stress is excessive
Motor reduction ratio、torque one、Deceleration ratio concept:That is, the transmission ratio of the reduction device,Its a kind of gear ratio,Refers to the instantaneous input speed and output speed in the deceleration mechanism Ratio of degrees,symbolically“i”expression。For example, the input speed is1500r/min,Output speed is25r/min,Then its deceleration ratio is:i=60:1。The general deceleration ratio of the deceleration mechanism is the actual deceleration ratio,However, some special reducers such as cycloidal reducers or harmonic reducers are sometimes rounded by rounding method,Without denominator,If the actual deceleration ratio may be28.13,And the annotation is generally annotated28。
