Description
Technical field
The present invention relates to a kind of main shaft devices for powder concentrator, are suitable for the row such as building materials, chemical industry, metallurgy, power plant, mine
In the powder concentrator of the grinding system of industry.
Background technique
Powder concentrator is important one of grinding system equipment, and material enters powder concentrator from chute, is imported material by chute
Grinding unit, material entered powder concentrator with internal gas flow direction after levigate, in the guide vane and rotation cage wheel of powder concentrator
Double action issue it is estranged from.Fine powder continue rise from air outlet of powder concentrator flow out, via select powder dust-precipitator, bag collector collect
Get off.Coarse powder settles under cage wheel centrifugal force and self gravitation effect, enters grinding unit grinding again via powder concentrator ash bucket.
Powder concentrator cage wheel needs to apply centrifugal force to granular material by rotation at work, and cage wheel is rotated around main shaft,
The driving torque of powder concentrator driving motor is passed to the rotation that cage wheel realizes cage wheel by main shaft.Main shaft is played the part of important in powder concentrator
Role is the important dynamic component of powder concentrator, needs to bear huge distorting stress.Traditional powder concentrator main shaft is usually solid
The defect of main shaft, this design is: because main shaft is important stressed member, being transmitted by powder concentrator driving motor by speed reducer
The torque effect to come over, main shaft twists damage inactivation in order to prevent, and main shaft generally uses high duty alloy Steel material to manufacture, and
And the diameter of axle be generally arranged it is larger, to make main shaft obtain biggish Torsion Section coefficient, be easy to cause in this way high-quality steel compared with
The big difficulty put into and fabricate.Main shaft and cage wheel are usually arranged to an entirety by traditional powder concentrator main shaft, are not easy to
Main shaft, cage wheel transport, be installed on maintenance.Usually the upper of main shaft is arranged in the upper and lower bearing of main shaft by traditional powder concentrator main shaft
End, main shaft lower part and cage wheel are easy to happen swing when operating, cause unfavorable shadow to upper and lower bearing and entire powder concentrator equipment
It rings.
Summary of the invention
It is an object of the invention to: in view of the deficiencies of the prior art, one kind is provided and is obtained under the premise of not increasing steel investment
Obtain the novel main shaft device of bigger torsional property.
The purpose of the present invention is realized by following technical proposals:
A kind of hollow main shaft device for powder concentrator, including axis (one), axis (two), Seamless Steel Structural Tubes (one), knot
Structure seamless steel pipe (two), flange (one), flange (two), the major part of main shaft are hollow structure, the shaft parts (one), method
Blue (one) is fixed by welding on Seamless Steel Structural Tubes (one), forms the top half of main shaft.The shaft parts (two),
Flange (two) is fixed by welding on Seamless Steel Structural Tubes (two), forms the lower half portion of main shaft.The main shaft it is upper
Cage wheel is installed between half part and lower half portion, passes through the company of matching flange on the flange (one), flange (two) and cage wheel
Cage wheel is fixed in connecting bolt, to form the main shaft device of complete set.
It is preferred that the main shaft in addition to upper and lower end, is in belly shirt.
In above scheme, the main shaft is not being increased using hollow design structure according to Torsion Section coefficient formulas
Under the premise of steel investment, bigger torsional property can be obtained.
It is preferred that company of the main shaft by matching flange on the flange (one), flange (two) and cage wheel
Cage wheel is fixed in connecting bolt, forms the main shaft device of complete set.
In above scheme, facilitate the main shaft, the transport of cage wheel, installation and maintenance.
It is preferred that the axis (one) and the Seamless Steel Structural Tubes (one), the axis (two) and the structure
With seamless steel pipe (two) by being welded and fixed.
In above scheme, facilitates the simplicity of the corresponding part of the main shaft, is reliably fixed.
It is preferred that the upper and lower bearing of the main shaft is separately positioned on the both ends of the main shaft, i.e. shaft parts
(1), at the axle journal of axis (two).
In above scheme, facilitates the main shaft and obtain better mechanical property at work, reduce the swing of main shaft.
Beneficial effects of the present invention: since the solid main shaft for having abandoned traditional uses hollow spindle, so that main shaft is identical
Under the premise of steel are put into, bigger Torsion Section coefficient can be obtained, the requirement of main shaft material can be thus reduced, use inferior grade
Steel replace high-grade steel, i.e., replace alloy steel products with the Seamless Steel Structural Tubes that can directly purchase in steel market
Expect the main material as main shaft, reduces purchase cost, decrease the machining workload of main shaft, reduce and be processed into
This.Meanwhile the design scheme of hollow spindle reduces steel investment in other words under the premise of not increasing steel investment, obtains bigger
Torsion Section coefficient, improve the torsional property of main shaft.Main shaft is connected by flange with cage wheel, and main shaft and cage wheel are increased
Detachability energy, main shaft, cage wheel can no longer be an entirety other than working condition, can be convenient to main shaft, cage wheel
Carry out separately machined manufacture, transportation, installation, maintenance.Each part of main shaft, which is connected by welding, becomes whole, ensure that main shaft works
When stability, simultaneous processing is simple and convenient, easily operated.Upper and lower bearing is set to the both ends of main shaft by main shaft, has abandoned biography
Upper and lower bearing is set to the upper end of main shaft and hang is used to install the scheme of cage wheel by system main shaft, and this avoid masters
Axis is during operation because the swing that load unevenly generates, improves the stress of bearing, improve the centering of main shaft
Performance.Mechanism concision and compact of the present invention, convenient disassembly are easy repair and maintenance, improve the anti-torsion performance of main shaft, improve axis
The stress held reduces the manufacturing cost of main shaft.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is scheme of installation of the present invention；
Label in figure is respectively: 1 axis (one), 2 Seamless Steel Structural Tubes (one), 3 flanges (one), 4 structure seamless steels
Manage (two), 5 flanges (two), 6 axis (two), 7 keys, 8 upper bearing (metal)s, 9 cage wheels, 10 lower bearings.
Specific embodiment
