Description
Technical field
The utility model relates to a kind of conveying machinery of micron mill, is specifically related to a kind of New Superfine Powder climbing upset end structure.
background technology
In the conveying machinery of daily micron mill, helical feed is one of conventional means.Conventional helical structure is simple, and what the sealing of axle head was generally used is packing_seal, and what bearing adopted is self-aligning roller bearing, can meet the level of coarse particle material to conveying.
But conventional conveyor screw uses in the time that the climbing of superfine powder is carried, and in material, the less fine powder of grain order can frequent direct-axis direction enter in bearing seat from lower end, causes the damage of bearing.Material fine powder spills the working environment that affects that can be serious simultaneously, causes dust airborne dust, like this for a long time, and staff's health is caused to very big infringement.When in material, a grain order less fine powder bleeds in bearing and gap of main reinforcement, self-aligning roller bearing friction is excessive, and can not bear very large axial force, is very easy to damage so conventional conveyor screw uses on climbing spiral.My company improves for conveyor screw for this reason, is mainly design is improved in the lower end of conveyor screw.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of New Superfine Powder climbing upset end structure, compact conformation, reasonable in design, between mass transport chamber and bearing, be designed with cavity, the structure that is covered with dust is set between cavity and bearing, ensure the leak tightness of bearing, increase detouchable oil enveloping structure at the cavity other end, not only can lubricating screw axle, can also be in material before the less fine powder of grain order enters cavity, the grease adhesion in most of sealed structure, can prevent by periodic oil change the damage that large area skimming wear causes.
To achieve these goals, the technical solution of the utility model is as follows:
New Superfine Powder climbing upset end structure, comprise conveyer housing, screw shaft, flange assembly, bearing seat, bearing, in conveyer housing, be provided with screw shaft, screw shaft termination is provided with flange assembly, it is characterized in that, described flange assembly comprises body flange, bearing block flange and be arranged on the flange support tube between body flange and bearing block flange, between flange support tube and body flange, be provided with oil enveloping structure, between oil enveloping structure and bearing block flange, form a cavity that can store material fine powder, bearing block flange one side and bearing seat are connected by screw, bearing block flange opposite side is provided with the circle that is covered with dust, the outer gland that is covered with dust that is provided with of the circle that is covered with dust, in bearing seat, be provided with thrust baring, between thrust baring and screw shaft, be provided with end ring.
Described oil enveloping structure comprises oil sealing flange, seal ring, seal cover cap, valve piston, elastic element, bolt, O type circle, lubricating cup, in oil sealing flange, be provided with annular oil duct, oil duct is provided with two openings at oil sealing flange sidewall, in an opening, be provided with lubricating cup, in another opening, be provided with valve piston, valve piston peripheral hardware has elastic component, and elastic element is provided with bolt outward; Oil sealing flange middle part is also provided with two hydraulic fluid ports, and oil port is provided with seal disc, forms an oil pocket between seal disc and oil sealing flange, is provided with O type circle in oil pocket, between seal disc and oil sealing flange and screw shaft, is equipped with seal ring.
