Device for Lubricating Bearings

The device for lubricating bearings, e.g., gas-blast, by surrounding the shaft with oppositely directed threads which supply oil to the bearings is distingusished by the fact that in order to provide lubricant to the low-speed shaft without increasing the dimensions and weight of the part, a sealing ring is placed on the high-speed shaft; this sealing ring limits the supply of oil to one of the bearings by forming a forcing chamber during rotation together with the threads and the housing of the bearings. The forcing chamber is connected by a channel with a cavity located between the threads of the low-speed shaft. (Author)
