Abstract
The utility model discloses a cooling device for a heavy-load high-speed spindle. The cooling device comprises the spindle, wherein one section of a driving end of the outer surface of the spindle is provided with a protruding step section, a groove serving as an oil channel is formed in the step section, a cooling jacket is sleeved on the spindle and connected with one section of a driven end of the spindle through two or more bearings, and a spacer bush is arranged between the bearing and the step section. An oil inlet and an oil return port are formed in the outer surface of the cooling jacket, the oil return port is connected with the groove in the step section of the spindle, an annular jacket with an oil hole is arranged between the two bearings, and the oil inlet is connected with a gap between the bearings through the oil hole of the annular jacket. Compared with the prior art, the cooling device for the heavy-load high-speed spindle can solve the problem that increase of rotation speed is influenced by poor cooling lubrication of the existing spindle.
Description
Technical field
The utility model relates to engineering machinery processing technique field, especially a kind of cooling unit for big machinery heavy duty high-speed main spindle.
Background technique
The main shaft of existing big machinery heavy duty is because its volume and weight is larger, guarantee again good coaxality, generally all adopt nature cooling, the mode of grease lubrication, allow main shaft pass through natural wind cooling, inject lubricant oil with lubrication in outerface of spindle timing.This lubricating system is simple and easy to do, do not need optional equipment, its shortcoming is that applicable rotating speed is lower, simultaneously owing to not adopting special cooling method, brought difficulty also to the further raising of spindle speed, thereby the high-speed main spindle of big machinery heavy duty is cooling and one of the lubricated technical bottleneck that becomes the sector.
Model utility content
Problem to be solved in the utility model is to provide a kind of heavily loaded high-speed main spindle cooling unit, bad to solve existing heavily loaded main shaft cooling and lubricating, and then affects the problem that rotating speed improves.
In order to address the above problem, the technical solution of the utility model is: this heavily loaded high-speed main spindle cooling unit comprises main shaft, one section of described outerface of spindle drive end is provided with protruding step section, described step section is provided with the groove as oil duct, at described spindle jacket, one coolant jacket is housed, one section of the driven end of described coolant jacket and described main shaft is connected by bearing, the intersegmental spacer that is provided with of described bearing and described step, described coolant jacket outer surface offers filler opening and return opening, described return opening is connected with the groove in described fast headstock stage, described bearing has two at least, between described two bearings, be provided with the ring set with oilhole, described filler opening is connected by the space between oilhole and the described bearing of described ring set.
In technique scheme, more specifically scheme can be: described coolant jacket outer surface is provided with the thread section of repairing screw thread point.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, increased this heavily loaded high-speed main spindle cooling unit, can use cold oil, main shaft has been carried out to cooling and lubricating, guaranteed, in the good situation of working condition that main shaft rotates, to improve rotating speed.Use after written or printed documents heavy duty high-speed main spindle cooling unit, its revolution of heavily loaded main shaft is brought up to 800 to 1000 revs/min from 600 revs/min of original left and right;
2, this heavily loaded high-speed main spindle cooling unit adopts special oil circuit setting, makes cold oil then enter coolant jacket along pipeline through oil cooling machine fuel feeding, bearing outer ring is carried out cooling, then has bearing outer ring return opening, oil return, and simple in structure, cooling and lubricating is effective;
3, the thread section structural design of this heavily loaded high-speed main spindle cooling unit coolant jacket outer surface, design guarantees that coolant jacket rotates arbitrarily angled all to the cooling increase cooling effect that impacts of bearing outer ring around axis.

Fig. 2 is the plan view of the utility model embodiment coolant jacket;
Fig. 3 is the left view of the utility model embodiment coolant jacket.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This heavily loaded high-speed main spindle cooling unit as shown in Figure 1, Figure 2, Figure 3 shows, comprise main shaft 1, one section of the outer surface drive end of this main shaft 1 is provided with protruding step section 2, step section 2 is provided with the groove 6 as oil duct, outside main shaft 1, be set with a coolant jacket 3, one section of the driven end of coolant jacket 3 and main shaft 1 is connected by bearing 8, between bearing 8 and step section 2, is provided with spacer 7, coolant jacket 3 outer surfaces offer filler opening 5 and return opening 4, in filler opening 5 and return opening 4, are provided with seal ring 9.Described return opening is connected with the groove 6 in described fast headstock stage 2, bearing 8 has two at least, here have three bearings 8 to be arranged side by side, wherein between one of centre and one, left side bearing 8, be provided with the ring set 10 with oilhole, filler opening 5 is connected by the space between oilhole and the bearing 8 of ring set 10.Make cold oil then enter coolant jacket 3 along pipeline through oil cooling machine fuel feeding, carry out cooling to bearing 8 outer rings, then there is bearing outer ring return opening, oil return, like this, can use cold oil, main shaft is carried out to cooling and lubricating, guarantee, in the good situation of working condition that main shaft rotates, revolution to be brought up to 800 to 1000 revs/min from 600 revs/min of original left and right.Coolant jacket 8 outer surfaces are provided with the thread section of repairing screw thread point, guarantee that coolant jacket rotates and arbitrarily angledly all impacts bearing outer ring is cooling around axis.Its spiral number of turns is 10 circles, and coolant jacket Thickness Ratio traditional come thin like this can be as much as possible with the heat of bearing outer ring.Coolant jacket 3 is also provided with lubrication hole 11.
Claims (2)
1. a heavily loaded high-speed main spindle cooling unit, comprise main shaft, it is characterized in that: one section of described outerface of spindle drive end is provided with protruding step section, described step section is provided with the groove as oil duct, at described spindle jacket, one coolant jacket is housed, one section of the driven end of described coolant jacket and described main shaft is connected by bearing, the intersegmental spacer that is provided with of described bearing and described step, described coolant jacket outer surface offers filler opening and return opening, described return opening is connected with the groove in described fast headstock stage, described bearing has two at least, between described two bearings, be provided with the ring set with oilhole, described filler opening is connected by the space between oilhole and the described bearing of described ring set.
