Description
Technical field
The utility model relates to the transmission device fields of double-stage vacuum extruding machine, and in particular to a kind of double-stage vacuum extruding machine
Junior's hitch bar.
Background technique
Double-stage vacuum extruding machine is our factory according to the practical national conditions in China, the flourishing state such as assimilate Germany, Italy, the U.S.
The advanced technology of family uses for reference the novel brick equipment that domestic and international advanced experience manufactures and designs.With it is structurally reasonable, sturdy and durable,
The features such as easy to maintain, adaptable.It is to be produced using the various raw materials such as clay, flyash, gangue, shale, river silt
The ideal equipment of various hollow brick solid bricks.
The junior of existing double-stage vacuum extruding machine is squeezed out using the conveying that a main shaft drives reamer carries out raw material, main shaft
It will receive the biggish resistance from raw material in use process, often the size and quality of main shaft are very big, so that the operating of main shaft
Biggish power is needed to input.The power of main shaft is usually to be directly output to main shaft by shaft coupling after speed reducer adjusts,
Since the quality of main shaft is excessive, existing shaft coupling uses rear generally existing angular displacement, radial displacement and axial displacement, makes winner
Exist in axis operation process and swing, operates unstable problem.
Utility model content
The utility model is intended to provide junior's hitch bar of double-stage vacuum extruding machine, is squeezed out with improving existing two-stage vacuum
Junior's main shaft of machine there are problems that swinging.
In order to achieve the above objectives, the basic technology scheme of the utility model is as follows: junior's shaft coupling of double-stage vacuum extruding machine
One side of device, including ring gear and external gear, external gear is offered integrally formed with coaxial axle sleeve, another side
Multiple along middle part equally distributed blind hole in a ring, there are two external gears, and two external gears are inserted into from the both ends of ring gear respectively
And engaged with ring gear, safety pole is plugged between the blind hole of two external gears, a blind hole is respectively inserted at the both ends of safety pole,
It is connected with end cap on the end face of ring gear, the site of engagement of external gear and ring gear is respectively positioned between two end caps.
The principle of this programme is: the connection and power transmission unit of ring gear and external gear as two axis, axle sleeve is for outer
The connection of gear and axis, can be processed keyway or spline structure inside axle sleeve, two external gears respectively with the output shaft of speed reducer and
Junior's main shaft of extruder connects, and carries out the connection between two axis by the synchro-meshing of two external gears and ring gear and moves
Power transmission, end cap are limited and are closed to the connection end of ring gear and external gear, and blind hole is used for installation insurance column.It is multiple blind
Uniform array is distributed between two external gears and forms radial connection reinforcement knot in a ring in the middle part of external gear for hole and safety pole
Structure, the safety pole that the radial displacement and angular displacement that main shaft is subject in use process had both passed through annular array undertakes, further through internal tooth
The tie point of circle upper end cover is shared, and using inside and outside dual bearing structure, the safety pole of annular array is connected outside two by blind hole
Gear, the radial displacement power between two external gears are undertaken by the safety pole of annular array, and radial displacement trend is by annular array
Safety pole limitation, radial load transmits between multiple safety poles in rotation process, avoids the connection between two external gears
Failure.Equally, the angular displacement being subject to carried by the safety pole of array, and partial insurance column is by tensile stress, position corresponding thereto
Safety pole is by compression, and the two makes safety pole, and there are curved trend, but limited at safety pole both ends by blind hole
Under the conditions of, the trend of angular displacement is prevented from.
The advantages of this programme, is: 1, can be effectively improved existing double-stage vacuum extruding machine junior transmission coupling structure use process
The radial displacement and angular displacement of middle appearance improve the swing easily occurred in double-stage vacuum extruding machine junior main shaft use process and ask
Topic；2, using inside and outside dual connection and bearing structure, the density of load of shaft connection place is higher, and long-time use process axis is not
It is also easy to produce swing；3, in the blind hole and safety pole of the middle part of the external gear of connecting shaft setting circular array as main supporting part
Position, compared to the structure that carrying is bolted in two ring gears of traditional use, end cap in this programme under same load condition
The torque that connection with ring gear is born is smaller, is less susceptible to be destroyed, the longer life expectancy of connection structure.
Further, the middle part of ring gear is equipped with the positioning plate of inwardly protruded annular, the inside of positioning plate be equipped with thickness and
The identical spacing board of positioning plate, spacing board are equipped with multiple through-holes corresponding with blind hole, and positioning plate and spacing board are respectively positioned on two
Between external gear, safety pole passes through the through-hole on spacing board.As preferred orientation plate and spacing board for separation while and internal tooth
The external gear of engagement is enclosed, and insertion depth of the external gear wheel in ring gear is positioned, so that ring gear internal structure is distributed
Uniformly rationally, it can also further the angular displacement of external gear wheel be defined by positioning plate, and spacing board is independently of ring gear,
Structural strengthening is carried out to the middle part of the safety pole of annular array between two external gears, limits the deflection of safety pole, reduces diameter
A possibility that generating to displacement and angular displacement, also avoids causing ring gear excessive load to cause to damage.
Further, the surface of positioning plate and safety pole is equipped with buffer coat, and the buffer coat for positioning plate surface is equipped with
Grid lines.Buffer coat as preferred orientation plate and safety pole surface is used to the phase generated between two external gears of buffering
To load, grid lines can increase the friction between external gear and positioning plate, be conducive to the mill for controlling radial displacement and external gear
Damage, the buffer coat on safety pole surface can increase the fatigue life of safety pole, so that safety pole bears radial load and distortion carries
The service life is longer in the case where lotus, buffer coat can also contact environment between external gear, ring gear and safety pole, reduction carries
Collision, friction noise under lotus.
Further, the engagement place of external gear and ring gear is equipped with threaded hole, and threaded hole half is located on ring gear, the other half
On external gear.As the connection that can be preferably further strengthened on the outside by bolt in this way between ring gear and external gear,
And it prevents from generating axial displacement between ring gear and external gear by screw thread.
Further, end cap is equipped with mounting hole, is equipped with bolt in mounting hole, is bolted in threaded hole.As preferred
Can carry out that external gear connect with ring gear while connection end cap in this way further strengthens, and dual by end cap and bolt
Carry out preventing for axial displacement.
Further, bolt uses coarse thread.As preferably use coarse thread can bear bigger axial load forces.
