With the development of our industry,The domestic gear motor market has shown a very prosperous development scene of supply and demand。The gear motor is a device that integrates the gear reducer and the motor,Because the gear motor combines the two into one,Relatively small size,The design is simple and space-saving,Therefore, it is widely used in various industrial builders in China。 More than 60 percent of Chinas total industrial power consumption is the consumption of various types of motor electric energy,therefore,Promoting the energy-saving development of Chinas gear motor is an important link to promote Chinas energy saving and emission reduction。Gear motor as a general mechanical product,The market demand is very high。China is the production of gear motor
Equipment overview: GK(H)Horizontal scraper discharge centrifuge is an intermittent centrifuge operated at constant speed。feed、separate、abstersion、Unloading and other processes can be automatically cycled at full speed according to the program。The filter cake treated by the centrifuge is dry,The range of solid particles can be processed is large(≥0.01mm)。 ↑ GKHHorizontal scraper discharge centrifuge ↑ GKHHorizontal scraper discharge centrifuge Working principle: When the machine works,Feed valve opens automatically,The suspension flows along the feed tube into a full-speed rotating drum,
At present, large and medium-sized hot runner system(Mainly used in the automotive industry)The world famous Shengvanti Injection Molding Industry Co., LTD,Will expand its product range downstream,Keep the injection volume to a minimum0.1g。For automobiles、A large number of multi-cavity molds for component manufacturing in the electrical and packaging industry and medical technology,Most have been delivered as hot half molds including temperature controllers。 The expansion of the product range,The determining factor was the development of four new nozzle families,There are two brand new ones03series,And two kinds04series,03and04The series are equipped with diameters of3.5and4.0Millimeters of standard runner straight
Tongs hot forging die shape inch150mm×95mm×110mmoriginal5CrMnMoSteel fabrication,The service life after conventional heat treatment is only0.4~0.5Ten thousand pieces。Primary failure formation:Early brittle fracture---The crack source occurs at the bottom corner of the stress concentration in the cavity;The thermal fatigue crack occurs at the edge of the cavity boss where the shock heat is most intense。The second is soft cavity collapse、Early failure such as plastic deformation and wear。The test shows that,Select and use4Cr2NiMoVThe electroslag steel of new type hot working die is subjected to composite enhanced heat treatment after being reformed and forged,Its service life4~5Ten thousand pieces,enhance9~10times,Have significant technical experience
Gear measuring tool for measuring involute tooth profile(See Length measuring tool)。There are two common single-disc and universal types。 Single-disk involute measuring instrument The base disc straightedge mechanism is adopted﹐To develop into a method(See gear measurement)Make a measurement(figure1 Single-disc involute measuring instrument )。The maximum diameter of the measurable gear is generally not greater than 600millimeter。When measuring gears of different diameters﹐It needs to be matched with the corresponding base disc。It is suitable for measurement in mass production5~6Grade precision gear﹐High accuracy can be measured3~4Grade precision gear。
Electromagnetic clutch to increase the lubricant Lubricant is often added to the moving part of the electromagnetic clutch。Check the length of armature stroke regularly。Because during the operation of the clutch,Due to abrasion of the split surface,The travel length of the armature will increase。When the armature stroke length does not reach the normal value,Adjustments must be made,To restore the minimum clearance between the brake surface and the turntable。If the armature stroke length increases above the normal value,The suction may be greatly reduced。If a worn brake surface is replaced,The brake surface should be properly adjusted between the turntable and the brake surface
