Deep groove ball bearing, lower part are the tapered roller bearing for bearing axially upwardly resistance of deformation, and middle cabinet is by main shaft, alignment bearing and master
Bearing installation is integrated, and is connected to press portion, separate section, deceleration part, constitutes a complicated structure, assembly installation
It is cumbersome, and base bearing is located at lower part, far from force part, makes biggish weakening to the intensity of main shaft.This double base main shaft
Structure is complicated for the Flat die granulating machine of structure, and main shaft stress is bad, and the more required precisions of process are high when assembly, be unfavorable for manufacturing and
Particle manufacture, to improve equipment dependability and energy-saving, improved there is an urgent need to the Flat die granulating machine to existing structure and
It improves.
Summary of the invention
The purpose of this utility model be directed to the inconvenience of raw material Flat die granulating machine main axle structure Complex Assembly problem problem, if
A kind of Flat die granulating machine of novel single-bearing supporting spindle structure type is counted
To realize the purpose of this utility model, using following technical solutions: single supporting spindle Flat die granulating machine, including
Chassis is connected with driving motor on chassis, and speed reducer is connected in the output of driving motor, during the top of speed reducer is connected with
Between cabinet, main shaft passes through middle cabinet up and down, connects speed reducer and press portion, hollow output shaft of the power by main shaft through speed reducer
Press portion is passed to across middle housing, the press portion includes the roller frame for being connected to main shaft top, and pressure roller is connected to
On roller frame, Flat die granulating machine is also configured with electric cabinet, and the output shaft of the speed reducer is hollow shaft, and the lower part of main shaft plugs
In hollow shaft, main shaft is concentric with hollow shaft, is connected by key in main shaft and hollow shaft, is provided in middle housing inner upper
Bearing block, base bearing are arranged in bearing block, and the base bearing is tapered roller bearing, on hollow shaft upper surface
There is a shaft shoulder portion on main shaft, be arranged with rubber pad on the main shaft between shaft shoulder portion and hollow shaft upper surface, rubber pad is pressed in axis
Between shoulder lower end surface and hollow shaft upper surface；Further；It is transition fit or gap between the main shaft and hollow shaft
Cooperation.
The positive advantageous effects of the utility model are: main axle structure is greatly simplified compared with original structure, not only optimizes
Stress more reduces processing cost；A base bearing is used only in drive mechanism, simpler in assembly, more efficient；Middle cabinet
Become tubular structure by simplifying, is not only convenient for producing, and cost also declines to a great extent；New construction has not only saved an axis
It holds, by structure optimization, main shaft stress is more preferable, and reliability improves；Manufacture assembly is simplified, and is significantly reduced and is produced into
This.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of former main axle structure.
Fig. 3 is the enlarged diagram for showing rubber pad position.
Specific embodiment
In order to more fully explain the implementation of the utility model, the embodiment of the utility model is provided.These implement real
Example is only the elaboration to the utility model, does not limit the scope of the utility model.
In conjunction with attached drawing to the further details of explanation of the utility model, respectively marked in attached drawing are as follows: 1: chassis；2: driving electricity
Machine；3: electric cabinet；4: main shaft；5: hollow shaft；6: speed reducer；7: middle housing；8: base bearing；9: rubber pad；10: pressure roller；11:
Bearing block；12: upper bearing support；13: lower support bearing.
Before the utility model is not transformed as shown in Fig. 2, originally using being duplex bearing supported freely supported structure, 12 in figure
For for original upper bearing support；13 be original lower support bearing.Upper bearing support is the deep groove ball bearing of centering, lower branch
Holding bearing is the tapered roller bearing for bearing axially upwardly resistance of deformation.
Single supporting spindle Flat die granulating machine of the utility model, including chassis 1, are connected with driving motor 2 on chassis 1,
