The main shaft of the pipe bender comprises a first shaft part, two chain wheel parts for installing chains to transmit the power, a second shaft part and a shaft-pressing part, wherein the two chain wheel parts are arranged at intervals in an axial direction and connected by a connecting shaft part; both of the two chain wheel parts are arranged between the first shaft part and the second shaft part; the first shaft part, the two chain wheel parts, the connecting shaft and the second shaft part are arranged integrally; and the shaft-pressing part is detachably installed on the first shaft part or the second shaft part, and a slot for installing a bearing ring of the main shaft is arranged between the end surface of the shaft-pressing part and the end surface of the first shaft part or the end surface of the second shaft part.
Description
Technical field
The present invention relates to a kind of main shaft, be meant the bending machine main shaft on a kind of bending machine especially.
Background technology
The main shaft of bending machine is an important components on bending machine, and its effect is: as the center of rotation of the bend pipe arm of bending machine, be used to install the bend pipe arm 1.; 2. be connected transferring power with chain.The main shaft of right present bending machine and with the sprocket wheel of chain transmission be the branch body structure, drive a keyway at first again on the main shaft, then sprocket wheel is installed through key and spindle, drive a keyway on the sprocket wheel again, then with chain through key and chain gear transmission installation.It mainly transmits this structure through two keyways and key, keyway and key easy abrasion and make transmission of power unreliable; Key and main shaft divide body structure in addition, therefore when assembling, bother very much complex operation.
Summary of the invention
Technical problem to be solved by this invention is: the bending machine main shaft that a kind of transmission of power is reliable, be convenient to the bending machine installation is provided.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of bending machine main shaft; Comprise the first axle part, be used to install two sprocket wheel portions, the second axle part and the last item portion of chain transferring power; Said two sprocket wheel portion axially spaced-aparts are provided with and connect through connecting axial region, and two sprocket parts are not arranged between the first axle part and the second axle part, and said the first axle part, two sprocket wheel portions, connection axial region and the second axle part are wholely set; This last item portion detachably is installed on the first axle part or the second axle part, is provided with the draw-in groove that is used to install main shaft load-bearing ring between the end face of this last item portion and the first axle part or the second axle part.
As a kind of preferred scheme, said last item portion and the first axle part or the second axle part screw thread are detachably installed.
As a kind of preferred scheme, said two sprocket wheel portions are the smooth sprocket wheel portion of side face, and said sprocket wheel portion is provided with axial keyway.
As a kind of preferred scheme, said keyway extends to the outer shaft end face of another sprocket wheel portion by the outer shaft end face of one of them sprocket wheel portion, and said shaft with key way is to running through the connection axial region.
After having adopted technique scheme, effect of the present invention is: owing to said the first axle part, two sprocket wheel portions, connection axial region and the second axle part are wholely set, therefore; Omit key and keyway between original sprocket wheel and the main shaft, make transmission of power more reliable and more stable, durability is better; This last item portion detachably is installed on the first axle part or the second axle part in addition; Be provided with the draw-in groove that is used to install main shaft load-bearing ring between the end face of this last item portion and the first axle part or the second axle part, therefore, sprocket wheel be installed in the sprocket wheel portion through key; Only need when mounted two installing plates of bend pipe arm are sleeved on the first axle part and the second axle part; Utilize main shaft load-bearing ring to be stuck in the draw-in groove then main shaft is carried out load-bearing, installation process is very simple and easy, has saved installation time.
Again because said keyway is extended to the outer shaft end face of another sprocket wheel portion by the outer shaft end face of one of them sprocket wheel portion; Said shaft with key way is to running through the connection axial region; Therefore; This keyway then is to be worked into another sprocket wheel portion from a sprocket wheel portion is directly disposable, and need not in two sprocket wheel portions, to open respectively, has saved process time like this.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the partial structurtes cutaway view of the embodiment of the invention;
In the accompanying drawing: 1. the first axle part; 2. sprocket wheel portion; 3. connection axial region; 4. the second axle part; 5. last item portion; 6. main shaft load-bearing ring.
The specific embodiment
Through specific embodiment the present invention is made further detailed description below.
As shown in Figure 1; A kind of bending machine main shaft comprises the first axle part 1, is used to install two sprocket wheel portions 2, the second axle part 4 and the last item portion 5 of chain transferring power, said two sprocket wheel portions 2 axially spaced-apart settings and connect through connecting axial region 3; Two sprocket wheel portions 2 are arranged at respectively between the first axle part 1 and the second axle part 4; Said the first axle part 1, two sprocket wheel portions 2, connect axial region 3 and the second axle part 4 is wholely set, it is cast as one, sprocket wheel portion 2 and connect and need not between the axial region 3 to install; Save installation steps and installing component, transmission of power is stable; This last item portion 5 detachably is installed on the first axle part 1 or the second axle part 4, is provided with the draw-in groove that is used to install main shaft load-bearing ring 6 between the end face of this last item portion 5 and the first axle part 1 or the second axle part 4.Said last item portion 5 and the first axle part 1 or the second axle part 4 screw threads are detachably installed.Said two sprocket wheel portions 2 are the smooth sprocket wheel portion 2 of side face, and said sprocket wheel portion 2 is provided with axial keyway.Said keyway extends to the outer shaft end face of another sprocket wheel portion 2 by the outer shaft end face of one of them sprocket wheel portion 2, and said shaft with key way connects axial region 3 to running through.Wherein the outer shaft end face is meant the end face near the first axle part 1 and the second axle part 4 that two sprocket wheel portions 2 are opposing; And in corresponding axial end be meant two sprocket wheel portions 2 adjacent near the end face that connects axial region 3.And why keyway is arranged to extended to by the outer shaft end face of a sprocket wheel portion 2 the outer shaft end face of another sprocket wheel portion 2; Said shaft with key way connects axial region 3 to running through; Its main cause is to consider the processing problems of keyway, to the main shaft keyseat time, directly from a sprocket wheel portion 2 to another sprocket wheel portion 2 disposable completion; And need not twice processing, save operation and time.
Operation principle of the present invention is: at first, two sprocket wheel portions 2 are that integrally casting forms with other positions of main shaft, have save the connected mode of a keyway and key, and rigidity and intensity all increase; Secondly, two gripper shoes of the bend pipe arm of bending machine are installed in respectively on the first axle part 1 and the second axle part 4, and utilize main shaft load-bearing ring 6 fix chucking, the installation of completion main shaft, installation process is easy and simple to handle.
