Imported bearing the correct installation and maintenance methods

1. The installation environment of imported bearings bearing in a dry, clean the environment to the preparing work before installation: the & # 8226; According to the different bearing size and application environment, use different installation method; • Ready to install the necessary parts, tools and equipment; • Ready for all the parts need to be installed and thoroughly cleaned before installation; • For all parts need to be installed according to the drawing size and shape accuracy check. Note: before installation preparation work not completed, don't unpack the imported bearing, lest make the pollution of bearing. 2. Installation of cylindrical hole bearing pressure into laws across surplus with small bearings, can use mechanical or hydraulic method will import bearing pressed into the shaft or housing. The heating method for large size bearings or interference quantity is large, can be installed by the use of principle of heat bilges cold shrink. Commonly used oil bath heating or electric induction heating method. Electric induction heating advantage: the & # 8226; Clean pollution-free & # 8226; Timing and constant temperature & # 8226; Simple operation 3. Cone bearing installation of inner hole for the taper hole of bearing is always installed by interference fit. 4. Bearing installation clearance adjustment for cylindrical hole of bearing, the radial clearance after its installation size tolerance of hole and shaft are chosen by the shell, the greater the amount of interference between them, after the installation of radial clearance. Therefore, the correct choice to match the imported bearings of the shaft and the hole tolerance is very important. For the installation of the cone bearing, the interference is like cylindrical hole of bearing inner hole, determined by the tolerance of the selected axis, and depends on the bearing on the conical journal or conical set into the distance on the set of length. Initial radial clearance of bearing in the process of into reduced gradually, and pushed into the amount of size decide to cooperate. Prior to installation, therefore, must first measure the initial import bearing radial clearance. In the process of bearing push, continuously measure the radial clearance, until meet the requirements of radial clearance is reduce the amount and range of the ideal. 1, first of all the imported bearing in gasoline cleaning, wipe the residues of sludge and dust on the bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel. 2, use dry cloth after cleaning the bearing wiped dry, soaked in the anti-rust oil again. In this process, will fully contact with the anti-rust oil bearing, don't stop rotating bearing, so that the rust-proof oil forming oil film covering on the surface of bearing, achieve the goal of rust. 3, the next with lithium base grease, butter, evenly coated on the surface of bearing, including inside and outside the circle, wheels, cage. And wipe while rotating bearing, makes the butter into the real bearing internal, sufficient lubrication effect. 4, the last procedure is packaging. In order to save costs, we 'waste', scrapping of cement bags in the warehouse, the packing bag of cut into appropriate size, package, wrapped tight will import bearing, with good bearing specifications after back on the store shelves. 5, the use of thermal monitoring at any time the bearing temperature. If the imported bearing in more than 125 ℃ temperature for a long time even move to reduce the bearing life.
