Description
Technical field
The utility model relates to a kind of spiral sub-material drive unit, particularly relates to a kind of spiral sub-material drive unit that is used for asphalt paver and Slipform Concrete Paver.
Background technology
Asphalt paver and Slipform Concrete Paver all belong to the pavement construction machinery in the engineering machinery, and the spiral distributor on the paver is its important equipment.The spiral distributor of existing paver is driven by the following extension case that is fixed on the frame.Because sub-material spiral axial dimension is big, following extension case and axle end bearing seat all are fixed on the frame, and axiality is difficult to guarantee.For this reason, following extension case and bearing support all adopt transfers terminal pad to hold, and perhaps the extension case adopts non-accent terminal pad to hold but increases by a cover cross groove shaft coupling between the case output shaft at helical axis and following the extension down.The maximum problem of this design is: (1) can not realize two-way sub-material; (2) hanging case down transfers the oil sealing at the terminal pad place of holding to damage easily; (3) cross groove shaft coupling is owing to the obstruction of the material that paves loses the aligning effect; (4) hang the case major part down and bear very big combined stresses effect, especially the radial load on the helical axis is easy to cause down the damage of hanging case to the moment of flexure and the radial load of hanging the generation of case output shaft down.
The utility model content
Technical problem to be solved in the utility model is the defective at existing structure, provides a kind of and can significantly improve down extension case sealing performance, reduces to hang case major part stress level down, can realize two-way sub-material and simple in structure, easily manufactured paver spiral sub-material drive unit.
In order to solve the problems of the technologies described above, the paver spiral sub-material drive unit that the utility model provides, comprise frame, under hang case and helical axis, described helical axis is made up of three parts: first is the sub-material spiral, second portion is for hanging the output shaft of case down, described output shaft and the described sub-material spiral of hanging case down is rigidly connected, third part is a terminal pad, the shaft extension of described terminal pad and oscillating bearing interference fit, the disk end of described terminal pad is rigidly connected in helical axis axis centre position and the described box body of hanging down, described whole helical axis is supported on the left shaft holder and right bearing seat that is fixed on the frame, described left shaft holder is self-aligning bearing and leaves certain axial stretching amount, described right bearing seat is for can bear the joint bearing block of bi-directional axial load, and described case one upper lateral part of hanging down inserts in the described frame by pin.
Be provided with a flexible guard circle at the described neutral place that hangs case and described joint bearing block down.
Adopt the paver spiral sub-material drive unit of technique scheme, whole helical axis is made up of three parts: first is the sub-material spiral; Second portion is for hanging the case output shaft down, and its shaft extension and sub-material helical axis are rigidly connected; Third part is a terminal pad; the shaft extension of terminal pad and oscillating bearing interference fit; and the disk end is rigidly connected in helical axis axis centre position and the following box body of hanging. and whole helical axis is supported on the left shaft holder and right bearing seat that is fixed on the frame. and left shaft holder is self-aligning bearing and leaves certain axial stretching amount; the right bearing seat is for can bear the joint bearing block of bi-directional axial load; the bi-directional axial power that produces during the spiral sub-material is born by joint bearing block fully. and the following extension case of this design and frame are unfixing; only upper design one pin in the one side inserts in the U-lag of frame; stop the rotation of hanging box body down; the moment of torsion of helical axis is delivered on the frame. therefore hang the only transfer torque driving helical axis rotation of case output shaft down; need not to adopt self-aligning bearing. because terminal pad that cooperates with oscillating bearing and the following box body of hanging are for being rigidly connected; so oscillating bearing has only the swing that nonconcentricity causes and does not rotate. can design a flexible guard circle at the neutral place that hangs case and joint bearing block down, the material that prevents to pave enters in the joint bearing block.
The beneficial effects of the utility model are: (1) realizes the two-way sub-material of spiral; (2) the reliable sealing difficult problem of hanging case down that solves; (3) save helical axis and the following cross groove shaft coupling of hanging between the case; (4) hang the reasonable long service life of case load down.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
Slip form paver spiral distributor for adopting the utility model patent to design shown in Figure 1, its right side is the screw drives device.Helical axis is made up of three parts: first is a sub-material spiral 12; second portion is for hanging the output shaft 11 of case 6 down; the output shaft 11 of hanging case 6 down is rigidly connected with sub-material spiral 12; third part is a terminal pad 10; the shaft extension of terminal pad 10 and oscillating bearing 8 interference fit; the disk end of terminal pad 10 is connected with following case 6 gear housing rigidities of hanging in helical axis axis centre position; whole helical axis is supported on the left shaft holder 1 and right bearing seat 9 that is fixed on the frame; left shaft holder 1 is for self-aligning bearing and leave certain axial stretching amount; right bearing seat 9 is for can bear the joint bearing block of bi-directional axial load; be provided with a flexible guard circle 7 at the neutral place that hangs case 6 and joint bearing block 9 down; hang case 6 one upper lateral parts down and insert in the U-lag of frame 5 by pin 4, following extension case 6 is provided with motor 2.
Referring to Fig. 1, be three parts with existing Function Decomposition of hanging case 6 down: (1) adopts the following extension case 6 of unique design.Its output shaft 11 is rigidly connected as a whole with sub-material spiral 12, under to hang case 6 fixing with frame 5, only design in the U-lag that a pin 4 inserts frames 5 hanging case 6 one upper lateral parts down, stop the rotation of hanging case 6 casings down, the moment of torsion of helical axis is delivered on the frame 5.Therefore hang the only transfer torque driving sub-material spiral rotation of output shaft 11 of case 6 down, need not to adopt self-aligning bearing.(2), joint bearing block 9 independently.This right bearing seat 9 is positioned at the rightmost of sub-material spiral 12.Be connected with the gear housing rigidity of hanging case 6 down in helical axis axis centre position with the terminal pad 10 of oscillating bearing 8 interference fit.Therefore, sub-material spiral 12, output shaft 11 and the terminal pad 10 of hanging case 6 down are same axises, but are bearing on the left shaft holder 1 and right bearing seat 9 of aligning at two ends, and the bi-directional axial power that produces during sub-material is born by joint bearing block 9 fully; (3), flexible guard circle 7.Hang flexible guard circle 7 of neutral place design of case 6 and joint bearing block 9 down, the material that prevents to pave enters in the joint bearing block 9.It is fixing that flexible guard circle 7 usefulness are pricked hoop, safeguards that replacing is convenient.
