注油器是汽轮机润滑系统中的主要部件,其扩散管的内孔呈锥形,设计规定,不但光洁度要求较高((?)抛光),而且内锥孔深度均较长(约1米左右),在一般车床上小拖板的自动行程较短,不能进行车削,为此必须具备能将小拖板扳一角度和大拖板一起联动行走刀的车床上加工,(我厂一般安排在小拖板和大拖板传动比为1:2.5714的捷克斯柯达5米大车上加工),这样在车削工艺中须要解决两个问题,刀杆的设计和小拖板所扳角度的计算。1 刀杆的设计由于内锥孔的深度长,因此刀杆必须设计成锥形(图1),为了增加刀杆的强度,刀杆
Lubricator is the main component of the turbine lubrication system, the inner diameter of the diffuser pipe is tapered, the design requirements, not only higher finish requirements ((?) Polishing), but also longer cone bore depth (about 1 meter) , In the general lathe small carriage short automatic travel, can not be turning, for which must be able to pull the angle of a small board and a large pallet move together with the lathe machining, (I plant generally arranged in a small The carriage and the large carriage drive ratio of 1: 2.5714 Czech Kodak 5-meter car), so in the turning process to solve two problems, the design of the arbor and the calculation of the angle of the small carriage. 1 Arbor design As the depth of the tapered bore, the arbor must be designed to be tapered (Figure 1), in order to increase the strength of the Arbor, arbor
