Abstract
The utility model discloses a device for connecting an extruder spindle and a reducer, comprising slider couplers. A cross plate-shaped slider is arranged in radial grooves at two side end surfaces of the slider couplers; and at least one slider coupler comprises first clamping shell and a second clamping shell which are combined together by a connection bolt. By adopting the scheme, the advantages of the two couplers are combined, and the technical effects of practicability and convenience for detachment are realized; in addition, when the couplers are used, if the cross slider in the middle is damaged, the connection bolt is detached, and the clamping shells are moved out in the radial direction, so that a certain dismounting and mounting space is provided, and further the device is convenient for dismounting and mounting.
Description
Technical field
The utility model relates to a kind of coupling arrangement, the coupling arrangement of particularly a kind of extruder main shaft and retarder.
Background technique
The coupling arrangement of extruder main shaft and retarder, commonly used have coupling arrangements such as oldham coupling and clamping coupling.Wherein, oldham coupling and clamping coupling are applicable to that all rotating speed is lower, and the connection of the axle that moment of torsion is bigger is particularly to use two kinds of coupling comparatively widely in the extruder in the building material machinery.
Oldham coupling is that the slide block of a cross plate-like in the middle of utilizing slides in the corresponding radial groove of both sides folder shell end face, with connection that realizes two folder shells and the ability that obtains the relative displacement of compensation diaxon.
Can know that by the structure of oldham coupling its diaxon that allows to connect has bigger radial displacement and allows little angular displacement.Because the working condition of extruder is poor, the based process of equipment is smooth inadequately, or equipment installs not too standard, or reason such as equipment underframe rigidity shortcoming, all can cause diaxon that coupling connects to not just, produces bigger radial displacement and certain angular displacement.
Oldham coupling in use can need to change because of the wearing and tearing or the breakage of crosshead shoe; But the restriction of its structure can't radially separate it; Can only separate dismounting vertically; At first need pull down the axle of a side when this just makes the dismounting coupling,, just need pull down speed reducer if side connection is speed reducer.So just strengthened the workload of device maintenance.
Clamping coupling is to utilize two folder shells (promptly pressing from both sides shell) of subdivision vertically, through tighting a bolt two folder shells is clamped on the cylindrical of axle, relies on frictional force and keyway between folder shell and the axle surface to come transmitting torque.
The characteristics of clamping coupling are convenient disassemblies, do not need to move vertically to carry out dismounting, because clamping coupling has these characteristics to make it on extruder, also obtain application.But clamping coupling requires the diaxon coaxality high, if when the diaxon coaxality is not high, will cause bigger additional load.So the use of clamping coupling has proposed high requirement to two-part processing in front and back and the assembly precision that coupling connects, thereby has increased manufacture cost and assembling difficulty.
Just because of the characteristics separately of oldham coupling and clamping coupling, they have all obtained application in tile machinery, but all can not satisfy application fully again.
The model utility content
In light of this situation, in order to overcome the defective of existing technology, the purpose of the utility model is to provide the coupling arrangement of a kind of novel extruder main shaft and retarder, has adjustable disposition; Overall compact is convenient to centering, and running steadily; Reliable performance, good rigidly, dismounting and change is characteristics easily.
It is following that the utility model solves the problems of the technologies described above the technological scheme that is adopted:
The coupling arrangement of a kind of extruder main shaft and retarder; Comprise that oldham coupling is provided with the slide block of a cross plate-like in the radial groove of the both sides end face of said oldham coupling; At least one of said oldham coupling comprises the first folder shell and the second folder shell, and it is combined through connecting bolt.
Further, preferred construction is that said folder shell is combined, and is fixed on above the periphery of axle.
Further, preferred construction is that said connecting bolt is set to two respectively in both sides.
The utility model is being taked such scheme, in conjunction with the advantage of two kinds of coupling, has reached the technique effect of practicability and convenient disassembly; And, when this coupling uses,, take connecting bolt apart if middle crosshead shoe damages, radially shift out two folder shells, can provide certain dismounting and installing space, for convenience detach and installation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 a is the structural representation of the coupling arrangement of the utility model extruder main shaft and retarder;
Fig. 1 b is the structural representation of the coupling arrangement of the utility model extruder main shaft and retarder;
Fig. 2 is the generalized section of the coupling arrangement of the utility model extruder main shaft and retarder.
Embodiment
Be described in detail below in conjunction with the structural principle and the working principle of accompanying drawing the utility model.
Fig. 1 a is the structural representation of the coupling arrangement of the utility model extruder main shaft and retarder;
As shown in the figure; The coupling arrangement of said extruder main shaft and retarder comprises, oldham coupling 7; Be provided with the slide block 6 of a cross plate-like in the radial groove of the both sides end face of said oldham coupling; The left side of said oldham coupling comprise first the folder shell and second the folder shell, its through connecting bolt with combine, its right side then is still the structure of a coupling.
Fig. 1 b is the structural representation of the coupling arrangement of the utility model extruder main shaft and retarder;
As shown in the figure, it has represented another embodiment's structural representation, among this schematic representation; More convenient in order to dismantle and to install, its both sides all are provided with and press from both sides the coupler structure that shell is formed, and said oldham coupling is set therebetween; And it is combined through connecting bolt 10 and 11, and; Said folder shell is combined, and is fixed on above the periphery of axle.
Fig. 2 is the generalized section of the coupling arrangement of the utility model extruder main shaft and retarder;
As shown in the figure, said folder shell 1 is combined through connecting bolt 10 with folder shell 2, and this connecting bolt has comprised bolt, nut and floor clip and formed.
The working principle of the utility model can be with reference to following description:
Be the advantage that the utility model has combined existing two kinds of coupling, allow the diaxon of its connection bigger radial displacement to be arranged and allow little angular displacement.And,, can not make transmission system produce bigger additional load even the front and back diaxon produces decentraction because of any reason or beats relatively.
And this coupling in use, if middle crosshead shoe damages, takes connecting bolt apart, radially shifts out two folder shells, can provide certain dismounting and installing space, for convenience detach and installation.
The utility model overall compact, but aligning are convenient to centering, and running is steady, reliable performance, and good rigidly, dismounting and change is convenient, has operability preferably for I&M especially, greatly reduces assembly precision and maintenance difficulty.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
