Whether the bearing device is correct or not; directly affects the accuracy, life and function of the bearing. Therefore, the device for drawing and the device part should be fully studied; according to the work specification. The operation specification items are usually as follows:
é€‘ é€‘ é€‘ å²¢ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Usually grease is smooth; does not remove the bearing; directly fills the smooth grease. When the oil is smooth; usually does not need to be removed; however; for instruments or high-speed bearings, etc.; to be cleaned with clean oil; remove the rust-proof coating on the bearing Agent. Remove the bearing of the rust inhibitor; easy to rust; so can not be placed at will.
Furthermore; bearings that have been sealed with smooth grease; do not clear directly.
Bearing device method; due to bearing layout, cooperation, conditions; because usually the shaft is rotated; so the inner ring needs to cooperate with the cooperation. Cylindrical hole bearing; multi-purpose press press; or hot-packing method. Cone hole occasion; Directly fixed on the tapered shaft; or with a tight sleeve device.
When the device is to the bearing seat; use the gap cooperation; when the outer ring has the interference; usually press with the press; or use the cooling method of the cooling device. Use dry ice as the coolant; cold shrink device; in the air The moisture will condense on the outer surface of the bearing. Therefore, it is necessary to adopt the anti-rust method.
