Lubricated pinion shaft group receives lubricant through shaft axial bore tube whose radial bores lead out to lubricating point of bearing roller.

摘要

A connection in the shaft (4) leads to the bearings (6,7) lubricating point and consists of a tube (5) led axially through the connection in the shaft. The connection has radial bores (8) connected by axial bore (3) and so out to the bearings, preferably roller bearings. The bearing has a holding disk (11) to take the axial forces and the connection is linked to the bearing points from between the fitted additional roller bearing (9) and the guide edge (10). The gear consists of housing (1) and lubricant intake channel (2) to lead the lubricant into the pinion shaft (4) as required. The channel (14) should be a rotary passage.
