Abstract
The utility model discloses a centrifuge comprising a main shaft (1) and fixed bearings. The centrifuge is characterized in that the three fixed bearings includes a sliding bearing (2) at the upper end of the main shaft (1), a thrust bearing (4) at the lower end of the main shaft (1), and a radial bearing (3) between the sliding bearing and the thrust bearing. The centrifuge has a good balance performance.
Description
Technical field
The utility model relates to a kind of centrifugation apparatus, particularly a kind of link-suspended basket centrifuge.
Background technology
Link-suspended basket centrifuge is a centrifugation apparatus commonly used in the existing industrial production, how improving separation factor in centrifuge production is the key problem of centrifuge design, the diameter and the rotating speed of separation factor and centrifuge have relation, separation factor is high more, the diameter of centrifuge and rotating speed are high more, but centrifuge vibrations just can't reduce more, and centrifuge principal axis Yin Wendu its stroke that raises is just big more under high speed rotating, and axial restraint is just difficult more.The fixed form of prior art centrifuge principal axis is that duplex bearing is fixed, axial restraint is fixed for utilizing gravity, be and utilize gyro principle to realize the raising of rotating speed, but because of material in producing often inhomogeneous, particularly therefore the material of solid-liquid mixing causes dynamic balancing very easily to change, and the result who causes is destroyed for dynamic balancing, centrifuge produces strenuous vibration, and machine breakdown takes place when serious.
Summary of the invention
The purpose of this utility model is to solve the prior art deficiency, provides a kind of dynamic balance performance good centrifuge.
The utility model is realized by the following technical solutions: a kind of centrifuge, comprise main shaft and rigid bearing thereof, and this rigid bearing comprises three, is respectively the sliding bearing that places the main shaft upper end, the thrust bearing and the marginal radial bearing of main shaft lower end.
The adjacent setting of this radial bearing and thrust bearing.
Compared to existing technology, the utility model is improved to three bearing fixing modes with the main shaft fixed form, sliding bearing and radial bearing have been increased, better solved at material and the difficult problem that dynamic balancing is very easily destroyed when inhomogeneous occurred, do not reduce simultaneously separation factor again, through actual motion, effect is obvious.Centrifuge after the improvement has adaptability widely, more is applicable to than ropy material.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, main shaft, 2, sliding bearing, 3, radial bearing, 4, thrust bearing.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described.The rigid bearing of the utility model main shaft 1 comprises three, be respectively the thrust bearing 4 of the sliding bearing 2 that places main shaft 1 upper end, main shaft 1 lower end and fall between and with the radial bearing 3 of thrust bearing 4 adjacent settings.Three bearings play different effects respectively, thrust bearing 4 plays the effect of axial restraint, solve the downward active force of main shaft in the rotation process 1, radial bearing 3 plays and overcomes the upwards effect of play of main shaft 1, sliding bearing 2 solves main shaft 1 and produces the problem of axial stretching because of temperature raises, and three bearings are used and preferably resolve main shaft 1 dynamic balancing problem of unstable.
Claims (2)
1. centrifuge, comprise main shaft (1) and rigid bearing thereof, it is characterized in that: this rigid bearing comprises three, is respectively the sliding bearing (2) that places main shaft (1) upper end, the thrust bearing (4) and the marginal radial bearing (3) of main shaft (1) lower end.
2. centrifuge according to claim 1 is characterized in that: this radial bearing (3) and the adjacent setting of thrust bearing (4).
