Abstract
The utility model discloses a kind of high speed shaft; High speed shaft mill frictional loss little elongate member working life is solved by fixing part, main shaft part, headstock portion, main pulley portion.For solving the problems of the technologies described above, the technical solution of the utility model is: comprise fixing part, main shaft part, headstock portion, main pulley portion, described fixing part is connected with main shaft part right-hand member, described main shaft part runs through whole headstock portion, described main shaft part is installed bearing supports main shaft portion to be connected with headstock portion, described main shaft part right-hand member is connected with main pulley portion.
Description
[technical field]
The utility model relates to a kind of high speed shaft, particularly relates to centrifuge principal axis.
[background technique]
Because centrifuge principal axis directly contacts with bearing, motor belt motor moving axis high-speed rotary will produce friction therebetween has friction to produce wearing and tearing, and the operating time, longer wearing and tearing were more serious.Therefore the wearing and tearing between axle and bearing will be reduced; the oil mass added between present centrifuge principal axis and bearing can only maintain in maintenance man hours; due to assembly precision maintenance personnel quality in factory's operation; overheated ability maintenance down causes bearing and bearing wear seriously to cause axle and bearing to occur, and lack of lubrication is the Frequently Asked Questions causing axle and bearing wear.
In view of above-mentioned defect, be necessary the high speed shaft designing a kind of continuous lubrication in fact.
[summary of the invention]
The utility model discloses a kind of high speed shaft; High speed shaft mill frictional loss little elongate member working life is solved by fixing part, main shaft part, headstock portion, main pulley portion.
For solving the problems of the technologies described above, the technical solution of the utility model is: comprise fixing part, main shaft part, headstock portion, main pulley portion, described fixing part is connected with main shaft part right-hand member, described main shaft part runs through whole headstock portion, described main shaft part is installed bearing supports main shaft portion to be connected with headstock portion, described main shaft part right-hand member is connected with main pulley portion.
Further, described fixing part comprises through hole.
Further, to comprise through hole some uniform for described fixing part.
Further, described fixing part comprises two bearings.
Further, described main shaft part comprises two oil grooves.
Further, described main shaft part comprises two annular grooves.
Further, described headstock portion comprises oil transportation hole.
Effectively lubricating effect is played in operating conditions by oil groove, the longer effective minimizing service time of its lubrication effect is made to extend bearing working life, the frictional loss of effective minimizing main shaft part and gear, effectively reduces the friction texturizing of main shaft part and the main shaft that brings and bearing wear.
[accompanying drawing explanation]
Fig. 1 shows galvanoscopic plan view partial sectional view.
Fig. 2 shows and galvanoscopicly opens oil groove partial view.
Following embodiment will in conjunction with the further the present invention of above-mentioned accompanying drawing.
[embodiment]
As shown in Figure 1, a kind of high speed shaft, comprise fixing part 1, main shaft part 2, headstock portion 3, main pulley portion 4, described fixing part 1 is connected with main shaft part 2 right-hand member, adopt interference fit to connect, described main shaft part 2 runs through headstock portion 3 really, installation shaft 5,6 supports main shaft portion and headstock portion 3 clamping in described main shaft part 2, and described main shaft part 2 right-hand member is connected with main pulley portion 4.Motor is rotated by drive main spindle portion of main pulley portion 42, fixing part 1 is driven to rotate by main shaft part 2, the bearing 5 that main shaft part 2 is installed, 6 with headstock portion 3 interference fit, the main shaft part 2 be included in headstock 3 drives oil groove 7, 8, exposed main shaft part 2 outside headstock portion 3 comprises annular groove 9, 10 main shaft part 2 are rotated and are driven the lubricant oil in headstock portion 3 to be main shaft part 2 and bearing 5, 6 provide lubrication, a lubricant oil part of splashing when main shaft part 2 is rotated can be trapped in lubrication in oil groove 7 and arrive the effect of bearing inner race and main shaft part, drive the oil lubrication bearing in headstock portion 3 effectively to extend main shaft part 2 by main shaft part 2 rotation and improve working efficiency working life with bearing.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
