Vertical circular circular cylindrical worm reducer has the advantages of circular circular cylindrical worm reducer,It also has the following characteristics:(1)The total gear ratio of the reducer can be adjusted flexibly ;The first1The stage adopts belt drive,The total transmission ratio can be adjusted by changing the diameter of the pulley.(2)The transmission belt is narrowVwith,High carrying capacity,The maximum number of tape roots is4The root,Reduction of The structure size is reduced。(3)The increase of span of worm-gear support,The stress condition of the output shaft is improved,The intermediate supporting link on the support can be eliminated,Raise the whole machine Significantly decrease。(4)Stud nuts are used to adjust the preload of the belt,Flexible operation,Simple and reliable。(5)
Aseptic cold filling equipment for different suppliers,There will be differences in the design of which stations? Difference one:Bottle transfer mode 1.Stainless steel bottle clamp clamp bottle mouth structure:Strong and durable,Do not touch the thread of the bottle,Avoid the bottle mouth secondary pollution,meanwhile,There is no need to adjust the equipment height when changing the bottle type,And guide、Wheel and other nylon parts,Greatly convenient operation; 2.Bottle bottom,Bottle body structure; 3.Stainless steel dial bottle mouth structure。 Difference two:The way the bottle sterilizes 1.Disinfectant soaking method:By setting the disinfectant concentration、wen
summarize The rotary flash dryer has reasonable design,Compact structure,novelty,Wide range of use。Be used as pigment、Fine chemical industry、pesticide、fertilizer、fodder、food、medicine、corpuscle、Chemical engineering、Light industry and other industries。Can achieve fast、Energy conservation、Large production of small equipment,Requirements for continuous operation,Be the first in China,It reached the advanced level in the 1990s。 Working principle Hot air inside inlet tube at suitable wind speed,follow
Check the bearing regularly[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 seal is to maintain the 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,To reduce power transmission
Worm gear reducer to lift rate,Generally, non-ferrous metal is used as worm gear,The worm is made of harder steel,Because it is sliding friction drive,During operation,It generates a higher amount of heat,The thermal expansion of the reducer parts and seals is different,Thus, gaps are generated on the mating surfaces,The oil becomes thinner as the temperature increases,Easy to leak。There are four main reasons,One is whether the material collocation is reasonable,The second is the surface quality of the meshing friction surface, The third is the choice of lubricating oil,Whether the amount added is correct,The fourth is the assembly quality and the use environment。
First of all,The structure design is reasonable and advanced at the same time,You have longer bearings[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。]Life span。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 machinery in the shaft
Stainless steel processing and construction DrawingDeep processing:Easy to produce friction heat, so use pressure resistance、High heat resistance stainless steel at the same time after the molding processing should remove the oil attached to the surface。 weld:Rust harmful to welding should be thoroughly removed before welding、oil、moisture、paint,Select the electrode suitable for the steel type。The spot welding interval is shorter than that of carbon steel,A stainless steel brush should be used to remove welding slag。After welding,To prevent local corrosion or loss of strength,The surface should be polished or cleaned。 Cutting and stamping:Because stainless steel is stronger than ordinary materials
Decelerating machinery manufacturing industry as the basic equipment industry of the national economy,It plays a strategic role in economic development,Its development is closely related to macro-economy。03、04With the rapid growth of macroeconomics in China,Chinas equipment manufacturing industry presents a good momentum of development,The growth rate has been refreshed all the way。05years,Machinery industry industrial production、sell、Product yield,Steady growth in export deliveries,But subject to fixed asset investment、Export slowdown and the impact of national macro-control policies,05The industry fell back to a certain extent last year。enter06years,The machinery industry has once again ushered in the spring of development,According to the National Development and Reform Commission economic operation
Domestic reducer industry manufacturers also coexist in various forms,Such as foreign-funded enterprises、Sino-foreign joint venture、State-owned enterprise、Joint-stock enterprises and individual enterprises,The scale has reached billions of yuan of annual output value,As small as a few million dollars。Foreign companies account for about a quarter of those sales。 In the manufacturing of reducer,At present, the number of domestic manufacturers is large,Such as Chongqing gearbox Co., LTD,Hangzhou forward gear box Co., LTD,Nanjing high precision gear Co., LTD,Xi an Heavy Machinery Research Institute,Luoyang heavy gear box Co., LTD,Jingzhou whale transmission machinery Co., Ltd. and other domestic mainstream products
