Abstract
The utility model discloses a kind of bearing support adopting labyrinth ring seal ring, comprises lubricating cup, pedestal base, upper bearing bracket, step, bearing, bearing both sides connect labyrinth ring seal ring respectively, connect lubricating cup above upper bearing bracket, arrange pedestal base below step.Labyrinth ring seal ring is made up of interior labyrinth ring and outer labyrinth ring, and interior labyrinth ring and outer labyrinth ring cooperatively interact and arrange, and outer labyrinth ring is connected with the some bolts of bearing support.The utility model uses labyrinth ring seal ring, does not produce high temperature during axle High Rotation Speed, avoids the high temperature using skeleton oil seal to produce, and extends bearing working life.
Description
Technical field
The utility model relates to the bearing support in a kind of horizontal centrifuge.
Background technique
Bearing in horizontal centrifuge plays the effect supporting bowl.Bearing support in traditional horizontal centrifuge, employing be that skeleton oil seal circle carrys out stuffing box bearing, bearing High Rotation Speed, outside framework oil seal produce high temperature, the working life of bearing is had a greatly reduced quality.There is outside framework oil seal and produce high temperature in the bearing support in traditional horizontal centrifuge, thus affects bearing working life.
Model utility content
The purpose of this utility model is to provide a kind of bearing support adopting labyrinth ring seal ring, solves outside framework oil seal in prior art and produces high temperature, thus affects bearing working life.
The technological scheme that the utility model adopts is: a kind of bearing support adopting labyrinth ring seal ring, comprise lubricating cup, upper bearing bracket, bolt, step, pedestal base, bearing, bearing both sides connect labyrinth ring seal ring respectively, lubricating cup is connected above upper bearing bracket, below step, pedestal base is set, labyrinth ring seal ring is made up of interior labyrinth ring and outer labyrinth ring, interior labyrinth ring and outer labyrinth ring cooperatively interact and arrange, setting that tooth on labyrinth ring seal ring is square with the axis, outer labyrinth ring is connected with the some bolts of metal (upper seat.
As the further improvement of technique scheme, lubricating cup is screw-down type grease cup, is fixedly connected with upper bearing bracket.
The utility model compared with prior art tool has the following advantages: use labyrinth ring seal ring, avoids the high temperature using skeleton oil seal to produce, and extends bearing working life.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure, 1 upper bearing bracket, 2 outer labyrinth rings, labyrinth ring in 3,4 labyrinth ring seal rings, 5 pedestal bases, 6 lubricating cups, 7 bolts, 8 steps, 9 bearings.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to a kind of bearing support adopting labyrinth ring seal ring of Fig. 1, comprise lubricating cup 6, pedestal base 5, upper bearing bracket 1, step 8, bearing 9, bearing 9 both sides connect labyrinth ring seal ring 4 respectively, lubricating cup 6 is connected above upper bearing bracket 1, pedestal base 5 is set below step 8, labyrinth ring seal ring 4 is made up of with outer labyrinth ring 2 interior labyrinth ring 3, interior labyrinth ring 3 cooperatively interacts with outer labyrinth ring 2 and arranges, setting that tooth on labyrinth ring seal ring 4 is square with the axis, outer labyrinth ring 2 connects with the some bolts 7 of metal (upper seat 1,8.
Lubricating cup 6 is screw-down type grease cup, is fixedly connected with upper bearing bracket 1.
Labyrinth seal is the belt sealing tooth establishing several to be arranged in order around rotating shaft, forms a series of gap and expansion cavity of damming between tooth and tooth, and sealed medium produces throttle effect when the gap by tortuous labyrinth and reaches the object of Drain Resistance.Owing to there is gap between the rotor of labyrinth seal and casing, without solid contact, needn't lubricate, and allow thermal expansion, adapt to the occasion of high temperature, high pressure, high speed-frequency.
The utility model uses labyrinth ring seal ring, does not produce high temperature when axle High Rotation Speed, avoids the high temperature using skeleton oil seal to produce, and extends bearing working life.
It should be noted last that, above embodiment is only unrestricted for illustration of the technical solution of the utility model, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
