The swing shaft is mounted in a swing shaft of the pentagonal frame by the aid of an upper end angle bearing and a lower end angle bearing, the cross arm is connected with the swing shaft and the grinding roll assembly, each angle bearing includes an upper ring and a lower ring, filleted angles manufactured on the tops of the lower ring form lower ring rails, filleted angles with the same size with those of the filleted angles of the tops of the lower rings are manufactured on inner orifices of the upper rings and form upper ring rails, steel balls arranged between each upper ring rail and the corresponding lower ring rail match with each other in size and are evenly distributed, and the steel balls are exposed among the upper rings and the lower rings. The bearings for the swing shaft adopts the form of angle bearings with the exposed rails, dust can enter the angle bearings without being accumulated as the open structures of the angle bearings, the entered dust is smoothly discharged along with rotation of the angle bearings, and the angle bearings rotate smoothly, thereby guaranteeing stable work of the grinding roll assembly.

Description

The suspension arrangement of pitch formula grinding roller of wheat flour-milling assembly and plum blossom frame

(1) technical field:

The utility model relates to the flour mill parts, is the suspension arrangement of a kind of pitch formula grinding roller of wheat flour-milling assembly and plum blossom frame specifically.

(2) background technology:

In the pitch formula flour mill, the suspension arrangement of grinding roller assembly and plum blossom frame comprises balance staff and transverse arm, and balance staff is installed in the pendulum axle sleeve of plum blossom frame by two ends gum cover or bearing, and transverse arm connects balance staff and grinding roller.The grinding roller assembly is subjected to centrifugal action and drives balance staff to swing during work, and balance staff then rotates in the pendulum axle sleeve of plum blossom frame, and the grinding roller concora crush rolls material on bull ring.

Dust from flying in mill chamber during work, the environment very severe, dust enters between the pendulum axle sleeve axis hole of balance staff gum cover and plum blossom frame, increase friction, cause the gum cover wearing and tearing, balance staff and axis hole gap increase, the vertical oscillation axis deviation of grinding roller, solution are frequently to change gum cover; Perhaps dust enters in the balance staff bearings at both ends by bearing cap, and to cause balance staff to rotate dumb owing to the accumulation of dust, influence the abrasive dust effect, and solution is to change bearing, and this is that cost is higher than the more hard work of replacing gum cover.

(3) utility model content:

At the deficiencies in the prior art, the purpose of this utility model is to have designed the suspension arrangement of a kind of non-maintaining pitch formula grinding roller of wheat flour-milling assembly and plum blossom frame.

Can realize the pitch formula grinding roller of wheat flour-milling assembly of above-mentioned purpose and the suspension arrangement of plum blossom frame, comprise transverse arm and balance staff, balance staff is installed in the pendulum axle sleeve of plum blossom frame by two ends rotatable support up and down, transverse arm connects balance staff and grinding roller assembly, different is that described rotatable support is the angle bearing of particular design, angle bearing comprises Shang Quan and Xia Quan, Xia Quan top rounding forms down the circle track, the upward circle inner orifice corresponding with the Xia Quan top fillet of same size forms down the circle track, tiltedly right going up is provided with size 1 coupling between circle track and the following circle track, equally distributed steel ball, the part spheroid of steel ball bottom expose between the Shang Quan and following circle of angle bearing.

Described angle bearing can not only bear axially, radial load, particularly open track can make the dust that enters discharge along with the rotation of steel ball, and enter systematic collection with the mill chamber negative pressure, can not cause the accumulation of dust in angle bearing, guarantee the operate as normal of balance staff.

The mounting means of described angle bearing is: the circle of going up of the following circle of upper corners bearing and lower end angle bearing tightly fits in the upper and lower port of pendulum axle sleeve, and the upper corners bearing down the following circle track of circle be higher than the port of pendulum axle sleeve, avoid the accumulation of dust in pendulum axle sleeve.

For preventing that big slightly material particles from entering the upper corners bearing, the upper corners bearing is provided with dust ring, and dust ring is taken in from angle bearing and is filled to the pendulum axle sleeve end face.

As a same reason, enter the lower end angle bearing for preventing big slightly material particles, the lower end angle bearing is provided with dust cap, and with the port setting that circle exceeds pendulum axle sleeve of going up of lower end angle bearing, dust cap is filled to from snare under the angle bearing and encloses to the pendulum axle sleeve end face.

Described balance staff has dynamic and static two kinds of set-up modes:

The one, balance staff swing, this moment balance staff the bearing installation position respectively with the following circle tight fit that goes up circle, lower end angle bearing of upper corners bearing.

The 2nd, balance staff is fixed, this moment balance staff the bearing installation position respectively with the following circle of upper corners bearing, lower end angle bearing go up the circle tight fit, the turning set that is placed in the balance staff two ends tightly fits in that circle and lower end angle bearing enclose down on the upper corners bearing.

Advantage of the present utility model:

In the suspension arrangement of the utility model pitch formula grinding roller of wheat flour-milling assembly and plum blossom frame, the angle bearing form that the balance staff bearing adopts track to expose, though dust can the entering angle bearing, but because the angle bearing track has adopted Open architecture, the dust that enters can not produce accumulation, but discharge smoothly along with the rotation of angle bearing, rotate the steady operation that angle bearing has smoothly guaranteed the grinding roller assembly.

The utility model is applicable to 3R, 4R, 5R, 6R type pitch formula flour mill.
