Jiaxing bearing small make up exclusive parsing engine lathe spindle bearing of the related knowledge

There is rotational, have HRB bearing ( ) Against the knowledge of ordinary lathe spindle bearing, jiaxing bearing group co. , LTD. The author want to speak today greatly, also don't hurry to my dear friends. Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. A, bearing combination design as shown is a common lathe spindle bearing structure. Support for the fixed end before. By double row cylindrical roller bearings with tapered bore and two one-way thrust ball bearings. Two one-way thrust ball bearings, respectively in two directions under axial load, the spring constant pressure preload, to eliminate the bearing clearance. Double row cylindrical roller bearing radial load. Can borrow the taper hole in shaft neck movement, to adjust bearing radial clearance, and can realize radial preload, in order to improve the stiffness of the main system. After bearing selection with cone hole of double row cylindrical roller bearings, inner ring and roller relative to the movement of the outer ring to fit axial thermal elongation, and can adjust the clearance and preload. This lathe spindle, because will work near the front bearing as a fixed end, bear the axial load of two directions, and other parts of the shaft is not affected by the effect of axial load. Both bearing adopts double row cylindrical roller bearings with tapered bore, can realize the radial preload, so the shaft bearing stiffness is larger. The bearing clearance can be adjusted, so the axis of rotation accuracy is higher. 2, cooperate with installation due to the cylindrical roller bearing outer ring by local load street is, therefore, should be the shell hole machining accuracy as a K6. Following the h5 level precision of the thrust bearing, cooperate with thrust bearing shell hole, shall be processed to H6 level precision. Three, lubrication and sealing lathe spindle bearing adopts the circulating oil lubrication, if directly with gear oil lubricated bearing at the same time, should be set filter unit. Lathe main shaft seal. General using w-shaped gap sealing device. When speed is high, do not contact seal should be adopted. Lest sealing ring friction heat diffusion, affect the machining accuracy of machine tool. If you are looking for the above jiaxing bearing group co. , LTD.
