Description
Technical field
The utility model relates to pressurized screen equipment technical fields more particularly to a kind of combined pressure to sieve spline structure.
Background technique
China largely uses waste paper pulp-making at present, and the large granular impurity content in raw material is high, increases to pulping equipment
Abrasion, reduce the service life of equipment.Therefore as early as possible to separate impurity from paper pulp, for improving equipment
Service life reduces installed power, guarantees that the key indexes such as quality of finished paper play an important role.
Combined pressure sieve uses commonly used in the tail sheet of scalping workshop section, and the big specification that can be effectively removed in paper pulp is miscellaneous
Matter reduces the loss to follow-up equipment, while reducing the fiber loss of slag removal.But common such combined type pressure in the market
Power sieve rotor lower end wheel hub is mostly pressed on flat key spindle nose by shaft end gland, and radial positioning, axis are done by cylinder roller bearing in upper end
To sliding.Such drive mechanism requires upper bearing room and lower part main shaft concentricity high, and dismounts inconvenience, needs first to remove bottom
Shaft end gland bolt increases the maintenance use cost of production cost and client.
Utility model content
The utility model in order to solve the problems in the prior art, provides a kind of combined pressure sieve spline structure, reduces
Concentricity requirement between rotor and main shaft, and safeguard convenient disassembly.
In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of combined pressure sieve spline knot
Structure, including main shaft, the main shaft are from top to bottom equipped with spline segment, thread segment and optical axis section, be arranged at the spline segment of main shaft with
Its spline housing matched, spline housing with rotor hub is detachable is fixedly connected；The optical axis section of main shaft is arranged with axle sleeve, main shaft
Thread segment be arranged with the locking nut being threadedly coupled with it, locking nut and axle sleeve upper end compression fit；The optical axis section of main shaft
It is upper that cutterhead, axle sleeve lower end and cutterhead compression fit are fixed at the lower section of axle sleeve.
The main shaft upper end is placed in rotor hub, and is equipped between rotor hub and axle sleeve and is surrounded spline segment and screw thread
The sealing dished cover of section, seal the upper end of dished cover with rotor hub is detachable is fixedly connected, seal dished cover lower end and the axis
Set is tightly connected.
Sealing ring is equipped between the upper end and rotor hub of the sealing dished cover.
It is realized and is tightly connected by oil sealing between the lower end and axle sleeve of the sealing dished cover.
The upper end of the sealing dished cover is fixedly connected with rotor hub by the way that bolt is detachable.
Sealing ring is equipped at the mating surface of the axle sleeve lower end and cutterhead.
Lock washer is also equipped between the locking nut and axle sleeve upper end.
The spline housing and rotor hub are by the pin that is arranged and bolt is detachable is fixedly connected.
The beneficial effects of the utility model：
The utility model optimizes the driving form of rotor, is fixed by traditional shaft end gland, flat key transmission, transformation
For without using the fixed activity cooperation of shaft end gland, spline drived form.Wherein spline housing and rotor hub are connected by bolt, are connect
Pin positioning, has detachability, replacement convenient for safeguarding.
Bolt is locked and is sealed with sealing ring between sealing dished cover one end and rotor hub, and the other end passes through oil sealing and axle sleeve
Sealing.It seals dished cover and rotor hub and axle sleeve rotates synchronously, sealing the oil sealing between dished cover and axle sleeve is static seal, is guaranteed
Sealing effect.
Main shaft top compresses axle sleeve by locking nut and lock washer, guarantees sealing ring between axle sleeve lower end and cutterhead
Sealing effect, and when adjusting cutterhead gap, the variation of axle sleeve height can also come by adjusting the locked position of locking nut
Compensation.
The spline structure of the utility model realizes spline slide connection, the concentricity between rotor top and main shaft be not necessarily to compared with
High request saves processing cost, and safeguards convenient disassembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of combined pressure of the utility model sieves spline structure, including upper end is placed in rotor hub
2 inner main axis 2, the main shaft 5 are from top to bottom equipped with spline segment, thread segment and optical axis section, be arranged at the spline segment of main shaft 5 and its
The spline housing 1 matched, spline housing 1 and rotor hub 2 are bolted, pin positions, and have detachability, convenient for safeguarding
Replacement.The optical axis section of main shaft 5 is arranged with axle sleeve 4, and the thread segment of main shaft 5 is arranged with the locking nut 7 being threadedly coupled with it, locking
Nut 7 and 4 upper end compression fit of axle sleeve are also equipped with lock washer 8 between 4 upper end of locking nut 7 and axle sleeve in the present embodiment.
Cutterhead 6,4 lower end of axle sleeve and cutterhead compression fit are fixed in the optical axis section of main shaft 5 at the lower section of axle sleeve 4, and this is matched
Conjunction face place is equipped with sealing ring.
5 top of main shaft compresses axle sleeve by locking nut 7 and lock washer 8, guarantees close between 4 lower end of axle sleeve and cutterhead 6
The sealing effect of seal, and when adjusting 6 gap of cutterhead, the variation of 5 height of axle sleeve also can be by adjusting the lock of locking nut 7
Tight position compensates.
Also, it is equipped with the sealing dished cover 3 for surrounding spline segment and thread segment between rotor hub 2 and axle sleeve 4, seals dished cover 3
Upper end and rotor hub 2 between bolt lock and sealed with sealing ring, sealing dished cover 3 lower end by oil sealing and axle sleeve 4 it is close
Envelope.Above-mentioned sealing dished cover 3 and rotor hub 2 and axle sleeve 4 rotate synchronously, and it is quiet close for sealing the oil sealing between dished cover 3 and axle sleeve 4
