How to assemable transmission needle bearings?
Installing a fully loaded transmission needle bearings is usually done using an auxiliary sleeve. At this point, the auxiliary roller or auxiliary sleeve supports the needle roller to prevent it from falling out. The shaft neck lifts the needle roller with its own chamfer, and as the transmission needle bearings slowly moves inward on the shaft neck, the auxiliary roller or auxiliary sleeve slowly exits until it is installed in the working position.
The outer diameter of the auxiliary roller and auxiliary sleeve should be 0.1-0.3mm smaller than the shaft diameter.
Then, push the auxiliary roller or sleeve that replaces the journal or transmission needle bearings inner ring into the outer ring hole, and align its end face with the installation shaft end face or the bearing inner ring end face already installed on the shaft. Then, use a press or hammer to tap and apply pressure.
Transmission needle bearings can also be installed in this way, by applying a thin layer of lubricating oil to the outer diameter of the auxiliary sleeve, inserting it into the outer ring of the bearing, so that the auxiliary sleeve and the outer ring of the bearing form an annular hole, and then installing the needle in the annular hole. After installing the needle roller, use the working shaft to push out the auxiliary sleeve.
For transmission needle bearings without inner or outer rings, a thin layer of lubricating grease can be applied to the rolling surface of the shaft or housing hole during installation, and the needle rollers can be tightly pressed against the lubricating grease at the installation site in sequence. When pasting the last needle roller, there should be a gap, and the size of the gap should be 0.5mm on the circumference of the transmission needle bearings.
