Distance, temperature of charge are high, material performance is special, and underslung bearing is extensively applied in conveying worm.General lifting
The version of bearing has three kinds:
(1) the hanger bearing body in underslung bearing and axle use oil seal type to be tightly connected.
(2) axle in underslung bearing and helical axis end flange rely on boss and the groove phase contract on flange of shaft end
Close, connected by articulation bolt.
(3) underslung bearing assembling back support rod is fixed relative to position with supporting seat so that underslung bearing setting height(from bottom) cannot
Regulation.
There is defect and the problem of the following aspects in practical work process:
(1), when the hanger bearing body in underslung bearing and axle use oil seal type to be tightly connected, chance high-temperature material, raw meal particle size are low
Etc. under some other more severe condition of work, material can penetrate into inside underslung bearing, causes sliding bearing abrasion and spiral shell
The clamping stagnation of spin axis is even shut down.
(2) underslung bearing axis and helical axis end flange are only boss and groove fit, when using articulation bolt to connect,
It is relatively difficult to ensure the linearity of card underslung bearing two ends helical axis.
(3) when conveying worm is installed, longitudinal straightness error exceedes License Value, and during long-play, radial centrifugal force makes
There is flexural deformation in helical axis, causes the interference of helical blade and housing, thus produces noise pollution, and housing and blade
Abrasion, motor load increases.
Utility model content
The purpose of this utility model is the defect existing for above-mentioned prior art, provides a kind of novel labyrinth centering to hang
Dress bearing, this bearing can effectively prevent material from entering inside underslung bearing, and then ensure helical axis straight line operationally
Degree.
In order to realize above-mentioned technical characteristic, what the utility model was used technology is characterized in that a kind of novel labyrinth is fixed
Heart underslung bearing, it includes axle, and the outer cover of described axle is equipped with sliding bearing, and the outer cover of described sliding bearing is equipped with hanger bearing
Body, described hanger bearing body coordinates with sealing ring and carries out end face seal to sliding bearing, and described seal ring set is contained in the outside of axle, institute
The outer cover stating sealing ring is provided with support bar equipped with pressure ring, the top of described hanger bearing body, and described support bar passes through double nut
Being fixedly mounted on support seat, described support bar uses hollow-core construction, is provided with lubricating cup at the termination position of support bar.
Described sealing ring uses multilayer circular step to match with the annular groove on hanger bearing body, is formed multi-layer sealed.
The position that described axle matches with helical axis end flange is provided with centralized positioning step, centralized positioning step with in
Match in heart positioning hole.
Centre bore within described support bar matches with the outer wall of sliding bearing, and described sliding bearing is machined with oiling
Hole, match with the centre bore of support bar like oil filler point.
The utility model has the advantages that:
1st, hanger bearing body and sealing ring are designed to mazy fit form, effectively prevent at high temperature, raw meal particle size
Under the adverse circumstances such as low, dust enters inside underslung bearing.
2nd, by increasing double nut on support bar, adjustable under hanger bearing is designed on the whole, it is ensured that two ends spiral shell
Spin axis connected by underslung bearing after on the same line.
3rd, the two ends of underslung bearing axis being designed with centralized positioning step, during assembling, this step embeds the end of helical axis
Portion's flange, accurate positioning, it is ensured that the linearity of two sections of helical axis after connection.
Brief description
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the utility model integral installation distribution structure schematic diagram.
Fig. 2 is that the utility model sealing ring forms seal ring structure schematic diagram with hanger bearing body.
Fig. 3 is the utility model centralized positioning ledge structure schematic diagram.
In figure: hanger bearing body the 1st, sliding bearing the 2nd, pressure ring the 3rd, sealing ring the 4th, axle the 5th, screw the 6th, helical axis end flange the 7th, nut
8th, seat the 9th, support bar the 10th, termination the 11st, lubricating cup the 12nd, centralized positioning step 13 is supported.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
Seeing Fig. 1-3, a kind of novel labyrinth centering underslung bearing, it includes axle 5, and the outer cover of described axle 5 is equipped with cunning
Dynamic bearing 2, the outer cover of described sliding bearing 2 coordinates to sliding axle with sealing ring 4 equipped with hanger bearing body 1, described hanger bearing body 1
Holding 2 and carrying out end face seal, described sealing ring 4 is sleeved on the outside of axle 5, and the outer cover of described sealing ring 4 is equipped with pressure ring 3, described
The top of hanger bearing body 1 is provided with support bar 10, and described support bar 10 is fixedly mounted on support seat 9 by double nut 8, described
