The design of conical refiner feed mechanism
Abstract: conical refiner feed mechanism is a drive mechanism can convert rotary motion to linear motion, Its main Function is to promote the main shaft axial movement. Conical grinding feed mechanism use the adjustable-speed motor as power and through the gear reducer drive shaft movement, so infinitely adjustable-speed function within the required range can be achieved.
This paper first introduced the conical refiner feed mechanism of the working principle, and then identified through the programme demonstrated its main structure and drive, and analysis of the structural characteristics of the transmission system . In this paper, the conical refiner feed mechanism of the main parts: feed shaft, planetary reducer, bearings carried out a detailed analysis, design, calculation and checking. The connection of a variety of forms of bearings are analyed and choice. The Key points and difficulties of this article is on the transmission system design calculation and checking. This article is also related to the lubrication system for analysis
Key words: conical refiner; feed shaft; adjustable-speed motor; planetary reducer
