The use of large machinery bearing what ?
Generally used in large-scale mechanical bearings , have the following characteristics:
A larger structural pieces , popular thing is that the volume will be larger machinery . Because the human equivalent bearing joints, large joints will be larger then the person's head .
Second, the speed of the mechanical axis was unhappy , low-speed heavy , because the most significant advantage is its big head bearings can withstand greater loads.
Third, there is generally a large bearing harsh environment. Because bearing big for small dust particles and impurities , it is not so easy to destroy bearings.
Meet the above criteria machinery: cranes, excavators, shield machine , mill , converter, wind power gearboxes, wind power spindle , crusher, cement mill , cement roller press , a large low-speed gearbox shaft and so on.
What heating large bearings
Large bearings there are two installation methods :
1 . Bearing diameter cylindrical hole , you can use hot charging method, such as electromagnetic induction heater or heating oil bath is . Electromagnetic induction heater can be used SKF, heating oil bath must pay attention to keep clean , pay attention to the purity of the oil.
2 inner diameter of tapered bore bearings can be installed using a hydraulic method , hydraulic pump , hydraulic nuts and other tools.
What method of bearing large demolition ?
When the shaft and the bearing is damaged in the process of dismantling the bearing , the general loss of time and material costs on to occur. In addition , using the wrong tools and technologies for dismantling operations may also make the operator at risk , especially the risk caused by the excessive force .
Introduce the necessary preparatory work and demolition methods applicable to cylindrical and conical base . Methods include mechanical , heating and hydraulic technology
