Described orifice plate is mounted in the center hole entry position of jack shaft, has an aperture on the central position of orifice plate, and the lubricant oil that injection is entered to orifice plate is blocked in pipe, and flows in the other end ball cage of jack shaft steel ball is lubricated and is dispelled the heat.
Described lubricant oil is to enter nozzle carrier by the fuel supply line of lubrication oil supply system, enters nozzle by oil supply hole, sprays and enters in ball cage through spout.Wherein spout I has an inclined hole at vents face, and the lubricant oil ejecting directly sprays towards the steel ball position of ball cage coupling; Spout II is a straight hole of opening on vents face, and the lubricant oil ejecting is to spray towards the center hole of jack shaft up-hole plate, is used for the ball cage coupling steel ball of the other end of lubricated jack shaft.
The two ends of described ball cage coupling steel ball are all provided with ball cage lid, form respectively a lubricating cavity, cover steel ball to guarantee to spray the lubricant oil entering, and be designed with liquid flow hole in the central position of the ball cage lid of lubricating cavity apart from covering on steel ball position, the lubricant oil that exceeds liquid flow hole position is flowed into oil return sleeve pipe by liquid flow hole, and draw back lubricating oil tank by lubricating oil system, realize the circulation of lubricant oil by lubricating oil system.
Compared with prior art, the invention has the beneficial effects as follows:
Adopt the mode of jet lubrication oil, solved preferably the lubricated and heat dissipation problem of ball cage coupling, work 600 hours at 6000 revs/min to 9000 revs/min when the rotational speed of ball cage coupling driving shaft, jack shaft, working state is good.Carry out overhaul, do not find that abrasion condition appears in any component, respond well.
