Abstract
The invention discloses a rotary driving shaft coupling, which comprises two connected separate structures, the side of the connected surface of each separate structure is provided with an annular boss, the side of the boss is provided with bolt holes, and the two separate structures are connected and locked by bolts; the upper part of each separate structure is provided with a key groove, the key grooves of the two separate structures communicate with each other, a long key is mounted in the key groove of one of the separate structures, a short key is mounted in the key groove of the other separate structure, and the long key is mounted in the key grooves of both separate structures. Since the rotary driving shaft coupling adopts the combination of the long key and the short key for connection and fixation, a driving shaft can be prevented from being deflected, and the fixing effect is better; because set screws are adopted to fix the lower part of each separate structure, the set screws further ensure that mutual torsional displacement cannot be produced between the driving shaft and the coupling; the whole structure is simple, and the use effect is good.
Description
Technical field
The present invention relates to a kind of swing rotational moulding machine equipment, wave the live axle coupling device on the rotational moulding machine specifically.
Background technique
The power output of the output shaft of existing swing rotational moulding machine generally need install coupling, coupling device additional.Owing to wave the rotational moulding machine in the process of work; The receive force direction and the size of working portion are constantly to change; The warping force that shaft coupling on the rotational moulding machine bears is not stable just also; So the requirement to shaft coupling is higher, common coupling can not satisfy intensity and the stability requirement of the output shaft of swing rotational moulding machine to shaft coupling.Based on foregoing, a kind of output shaft stability in swing rotational moulding machine working procedure that guarantees swing rotational moulding machine is provided, and itself has the coupling device of sufficient intensity, be the technical problem that the present invention will solve.
Summary of the invention
The objective of the invention is to design a kind of rotating driveshaft shaft coupling, guarantee the stability of swing rotational moulding machine in the process of work, and shaft coupling itself has enough intensity.
The object of the invention comes concrete the realization through following technological scheme:
A kind of rotating driveshaft shaft coupling comprises two branch body structures of butt joint, divides the sidepiece of the interface of body structure to be provided with the boss part of hoop at each, has bolt hole in the side of said boss part, through bolt two branch body structures is connected and locking; Divide the top of body structure to be respectively equipped with keyway at each; The keyway of two branch body structures communicates; In the keyway of a branch body structure long key is installed therein, short key is installed in the keyway of another minute body structure, said long key is installed in the keyway of two branch body structures simultaneously.
On the lower sides of each branch body structure, have two bolts hole, each bolt hole inside is equipped with and holds out against screw, and each screw holds out against on transmission shaft respectively.
Rotating driveshaft shaft coupling according to the invention, the mode that adopts long key, short key to combine connects fixing, can prevent that deflection from appearring in transmission shaft, and its fixed effect is better; Fix and divide the bottom employing of body structure to hold out against screw at each, so just further guaranteed can not produce between transmission shaft and the shaft coupling mutual torsional displacement, total is simple, and using effect is good.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural drawing of the said rotating driveshaft shaft coupling of the embodiment of the invention.
Embodiment
As shown in Figure 1; The described rotating driveshaft shaft coupling of the embodiment of the invention; Two branch body structures 1 that comprise butt joint; Divide the sidepiece of the interface of body structure 1 to be provided with the boss part 2 of hoop at each, have bolt hole 3, two branch body structures 1 are connected and locking through bolt 4 in the side of said boss part 2; Divide the top of body structure 1 to be respectively equipped with keyway 5 at each; The keyway 5 of two branch body structures communicates; In the keyway 5 of a branch body structure long key 6 is installed therein, in another minute body structure keyway of 1, short key 7 is installed, said long key 6 is installed in the keyway 5 of two branch body structures simultaneously.
On the lower sides of each branch body structure 1, have two bolts hole 8, each bolt hole 8 inside is equipped with and holds out against screw 9, and each screw 9 holds out against respectively on transmission shaft 10.
Rotating driveshaft shaft coupling according to the invention, the mode that adopts long key, short key to combine connects fixing, can prevent that deflection from appearring in transmission shaft, and its fixed effect is better; Fix and divide the bottom employing of body structure to hold out against screw at each, so just further guaranteed can not produce between transmission shaft and the shaft coupling mutual torsional displacement, total is simple, and using effect is good.
Claims (2)
1. rotating driveshaft shaft coupling; Comprise two branch body structures of butt joint, it is characterized in that, divide the sidepiece of the interface of body structure to be provided with the boss part of hoop at each; Side in said boss part has bolt hole, through bolt two branch body structures is connected and locking; Divide the top of body structure to be respectively equipped with keyway at each; The keyway of two branch body structures communicates; In the keyway of a branch body structure long key is installed therein, short key is installed in the keyway of another minute body structure, said long key is installed in the keyway of two branch body structures simultaneously.
