Description
Technical field
The utility model relates to a kind of disc mill for the preparation of wood fibre, relates in particular to the syndeton of main shaft and the Moving plate of disc mill, belongs to wood-based plate manufacturing equipment technical field.
Background technology
Disc mill be under certain steam pressure or condition of normal pressure with the chip raw material continuous separate from the special equipment that becomes fiber, chip raw material is separated into wood fibre by the lapping device of disc mill.Lapping device comprises Moving plate and price fixing, and abrasive disc is housed respectively on Moving plate and the price fixing, and Moving plate is fixed on main shaft one end, with the main shaft High Rotation Speed; Price fixing is fixed in the housing of mill chamber, has formed the mill chamber that certain grinding space is arranged between Moving plate and the price fixing.The repeated External Force Actings such as the mill of chip raw material between Moving plate and price fixing be indoor by compression, stretch, reverse, impact, friction finally are separated into wood fibre.In the wood fibre preparation process, the main shaft of disc mill also will bear and grind the axial propulsive thrust that Raw interacts and produces in transmitting torque, and can the firm Degree of Accord Relation that main shaft is fixedly connected with Moving plate work stably in a long term to disc mill.
Existing disc mill spindle end is fixedly connected with by lining with Moving plate, the endoporus of lining is taper hole, described taper hole and spindle end tapering match, the lining periphery is cylindrical, have some annular oil grooves on the taper hole inner peripheral surface, the radial direction oil hole of annular oil groove by spindle end with lead to the axial oilhole of spindle end and link to each other.During the assembling Moving plate, first lining is contained in the Moving plate central inner hole, again Moving plate together is enclosed within on the spindle end together with lining, then the Moving plate end face is exerted pressure, lining taper hole and spindle end tapering are fitted tightly.Meanwhile, apply hydraulic oil by the axial oilhole to spindle end, the elastic tapered bore distortion of lining is swollen, in the process that the Moving plate end face is further exerted pressure, Moving plate moves down along the spindle end axis, lining taper hole and spindle end close fit; After the hydraulic oil unloading, the lining taper hole restores to the original state, and Moving plate is tightly embraced spindle end by lining, realizes that by interference fit Moving plate, lining are connected with the tight of spindle end three.The process of dismounting Moving plate is identical with said process, also is to apply hydraulic oil by spindle end, so that lining taper hole and centre bore strain swell, eliminates the interference between Moving plate centre bore and the lining taper hole, can take off smoothly Moving plate.
Disc mill Moving plate after long-term the use is through repeatedly mounting or dismounting, and liner wear, distortion seriously cause the quality of fit of Moving plate and main shaft to reduce, and have had a strong impact on the installation and operation precision of disc mill, so that the wood fibre Quality Down that separates; And this lining is difficult for processing reparation.In addition, main shaft is long-term use after self precise decreasing, because the wall thickness of lining is thinner and have some distortion, when the needs reparation or when again making main shaft, the termination conical surface of its key position is difficult to guarantee the quality of fit with the lining internal taper hole, the user has to customize lining and main shaft to supplier specially, has increased maintenance cost, has prolonged the maintenance of equipment cycle.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, processing cost is low, mounting or dismounting are convenient, the disc mill main shaft of long service life and the syndeton of Moving plate.
The utility model is achieved by the following technical programs:
The syndeton of a kind of disc mill main shaft and Moving plate, comprise main shaft, Moving plate, ball seat oil film plane bearing, two journal bearings, locking nut and Moving plate bellmouth elasticity bearizing mechanisms, described ball seat oil film plane bearing two supporting sphericals relatively are supported near on main shaft one end of Moving plate, and two journal bearings are supported on respectively on the main shaft axle journal in a pair of ball seat oil film plane bearing outside; Spindle end is pyramidal structure, and the Moving plate center is provided with the Moving plate bellmouth that cooperates with spindle end, and spindle end and the Moving plate bellmouth interference fit by the bellmouth axle is fixedly connected with and is integral, and by locking nut Moving plate is positioned on the spindle end.
The purpose of this utility model can also further realize by following technical measures.
The syndeton of aforesaid disc mill main shaft and Moving plate, wherein said Moving plate bellmouth elasticity bearizing mechanism comprise the axial oilhole that is arranged on the spindle end, with the radial direction oil hole of the axially vertical perforation of oilhole and the cannelure on the spindle end side face, described radial direction oil hole and cannelure perforation.
The syndeton of aforesaid disc mill main shaft and Moving plate, wherein the spindle end of taper and Moving plate bellmouth also link into an integrated entity by flat key.
The syndeton of aforesaid disc mill main shaft and Moving plate, wherein said cannelure closed at both ends, the two ends of sealing lay respectively at the keyway both sides.
Compared with prior art, the utility model is not established lining in the syndeton of spindle end and Moving plate, the accuracy of manufacture of spindle end and Moving plate centre bore taper fit is guaranteed, solve original structure and had liner wear, distortion seriously, the problem that causes the quality of fit of Moving plate and main shaft to reduce has improved the installation centering precision of Moving plate.Simultaneously, the user does not need to customize lining and main shaft to supplier specially, has reduced maintenance cost, has shortened maintenance cycle.
Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
