The bushing gland is fixed on by bushing gland trip bolt on bearing block；
The cross section of the spiral channel has spiral channel medial surface, spiral channel into a rectangle, spiral channel
Working face and three, spiral channel back side face；
The hand of spiral of the spiral channel and the direction of rotation of axis are oppositely arranged；
The spiral channel is uniformly provided with 4 or 6；
The spiral channel working face is provided with the outer rim molded line cornerite that cornerite is 60 ° or 90 °, spiral channel working face
The distance between spiral channel back side is 3-4 millimeters, and the depth of spiral channel is 2-3 millimeters, the axial length of spiral channel
It is consistent with axial length on the outside of axle sleeve；
The spiral channel is formed by lathe grinding, spiral channel surface roughnessR aNo more than 5μm。
The beneficial effects of the utility model：Practicality, production cost is low, structure novel, passes through the slip in high-temperature melting salt pump
Several spiral channel is provided on bearing axle sleeve, coordinates other structures, by the rotation of pump shaft, spiral channel rotation is made to generate pumping
Effect so that lubricant medium is full of runner and quickly flows, and realizes good lubrication effect, effectively prevents sliding bearing
Excessive wear, extend sliding bearing service life, it is ensured that high-temperature melting salt pump stable operation.

Specific embodiment
A kind of high-temperature melting salt pump self-lubricating bearing device, including axis 9, axle sleeve 8, bushing 6 and bearing block 4, the axis 9
Outside is arranged fixed hub 8, and axle sleeve 8 is mounted in bearing block 4, and bushing 6 is set between bearing block 4 and axle sleeve 8, and bushing 6 is installed
In the outside of axle sleeve 8, bushing 6 is mounted in bearing block 4, the gear for blocking bushing 6 that bends inwards of 4 lower end of bearing block
Plate, the upper end of bearing block 4 are fixed with the bushing gland 3 for covering bushing 6, and the both ends of axle sleeve 8 reach the outside of bushing 6, axis 9
Both ends reach the outside of axle sleeve 8, be uniformly provided with several spiral channels 2 on the outer wall of axle sleeve 8, the lower end of axle sleeve 8 opens up
There are lubricant medium inlet channel, upper end to be provided with lubricant medium outlet flow.
During high-temperature molten salt pump operation, 9 high speed rotation of axis, lubricant medium enters from 8 lower end lubricant medium inlet channel of axle sleeve
