Set is arranged in bearing block, and the baffle plate for blocking bushing that bends inwards of bearing block lower end, the upper end of bearing block is fixed with
The axle bush gland of bushing is covered, the both ends of axle sleeve reach the outside of bushing, and the both ends of axle reach the outside of axle sleeve, axle sleeve
Outer wall on uniformly offer some spiral channels, the lower end of axle sleeve offers lubricant medium inlet channel, upper end is provided with lubrication
Media outlet runner；
Keyway is offered on the outer wall of described axle；
Described axle sleeve is fixed on axle by axle sleeve trip bolt；
Described axle bush gland is fixed on bearing block by axle bush gland trip bolt；
Into a rectangle, spiral channel has spiral channel medial surface, spiral channel work for the cross section of described spiral channel
Face and three, spiral channel back side face；
The hand of spiral of described spiral channel and the direction of rotation of axle are oppositely arranged；
Described spiral channel is uniformly provided with 4 or 6；
Described spiral channel working face is provided with the outer rim molded line cornerite that cornerite is 60 ° or 90 °, spiral channel working face and spiral shell
The distance between spin slot road back side is 3-4 millimeters, and the depth of spiral channel is 2-3 millimeters, the axial length and axle of spiral channel
Set outside axial length is consistent；
Described spiral channel is formed by lathe grinding, spiral channel surface roughnessR aNo more than 5μm。
Beneficial effects of the present invention：Practicality, production cost is low, and structure is novel, passes through the sliding bearing in high-temperature melting salt pump
Several spiral channel is provided with axle sleeve, coordinates other structures, by the rotation of pump shaft, spiral channel is rotated and produces pumping work
With so that lubricant medium is full of runner and quickly flows, and realizes good lubrication effect, effectively prevent sliding bearing
Excessive wear, extend sliding bearing service life, it is ensured that high-temperature melting salt pump stable operation.
