The main chain wheel fo the main chain wheel device is reasonably installed and the speed reducer of the main chain wheel device is not acted by a tensile force of a cantilever, so that the service life is prolonged and the pipe bending accuracy is improved.
Description
Technical field
The utility model relates to a kind of main chain wheel device, refers to especially a kind of tube bender main chain wheel device.
Background technique
The structure of the main chain wheel device of present tube bender generally is to comprise motor, this motor is fixed on the frame of tube bender, the output shaft of motor is connected with retarder, on the output shaft of retarder main chain wheel is installed, and this main chain wheel drives rotation by the output shaft of retarder, like this, the similar cantilever of the installation of main chain wheel is installed, and main chain wheel produces a cantilever moment to the output shaft of retarder, in bend pipe, retarder is subject to the cantilever pulling force and easily breaks down, and has also affected the bend pipe precision of tube bender.
The model utility content
Technical problem to be solved in the utility model is: a kind of tube bender main chain wheel device is provided, and the main chain wheel of this main chain wheel device is installed rationally, and the retarder of main chain wheel device is not subjected to the effect of cantilever pulling force, thereby increases the service life, and improves the bend pipe precision.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tube bender main chain wheel device comprises motor; The retarder that is connected with motor output shaft; The driving axle box that is fixedly connected with reducer shell; Be installed on the main chain wheel on the output shaft of retarder, this main chain wheel is positioned at driving axle box, and the auxiliary support apparatus that the described main chain wheel of supplemental support rotates is installed on the casing of described driving axle box.
As a kind of preferred scheme, described auxiliary support apparatus comprises the dunnage of the casing end of being fixed in driving axle box; Be fixed in the back shaft on the dunnage, this back shaft extend in the main chain wheel axis hole, is set with the spring bearing that supports main chain wheel on the described back shaft.
As a kind of preferred scheme, described auxiliary support apparatus comprises a flange bearing, and the bearing portion of described flange bearing extend into the main chain wheel axis hole and supports described main chain wheel, and the flange part of described flange bearing is connected with the casing end bolt of driving axle box.
As a kind of preferred scheme, described retarder is planetary reducer.
After having adopted technique scheme, effect of the present utility model is: because described main chain wheel device also comprises auxiliary support apparatus, this auxiliary support apparatus is owing to being mounted on the casing of driving axle box, and supporting main chain wheel, main chain wheel bears support force by auxiliary support apparatus, this support force acts on the casing of driving axle box, therefore, main chain wheel is by the output shaft of retarder not being produced radially pulling force, the output shaft of retarder and main chain wheel do not consist of cantilever structure, prolong the working life of retarder, and the bend pipe precision of tube bender improves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's structure sectional view;
In the accompanying drawing: 1. motor; 2. retarder; 21. output shaft; 3. driving axle box; 31. casing; 4. main chain wheel; 5. dunnage; 6. back shaft; 7. spring bearing; 8. chain.
Embodiment
Below by specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of tube bender main chain wheel 4 devices comprise motor 1, and this motor 1 is preferably actuating motor 1; The retarder 2 that is connected with motor 1 output shaft; The driving axle box 3 that is fixedly connected with retarder 2 housings; Be installed on the main chain wheel 4 on the output shaft 21 of retarder 2, this main chain wheel 4 comprises an axis hole, and this axis hole is installed on retarder 2 output shafts 21, and described retarder 2 is preferably planetary reducer 2.This main chain wheel 4 is positioned at driving axle box 3, and the auxiliary support apparatus that the described main chain wheel 4 of supplemental support rotates is installed on the casing 31 of described driving axle box 3.
Wherein, described auxiliary support apparatus comprises the dunnage 5 of casing 31 ends of being fixed in driving axle box 3; Be fixed in the back shaft 6 on the dunnage 5, this back shaft 6 extend in main chain wheel 4 axis holes, is set with the spring bearing 7 that supports main chain wheel 4 on the described back shaft 6.This spring bearing 7 is supporting the axis hole of main chain wheel 4, does not hinder again the rotation of spring bearing 7 when guaranteeing support force, and wherein, back shaft 6, spring bearing 7, main chain wheel 4, retarder 2 output shafts 21 all will guarantee concentric.Back shaft 6 can be to be welded on the dunnage 5, also can be that screw connects.
Certainly, dunnage 5, back shaft 6, spring bearing 7 these threes can be the members of an integral body.Be that described auxiliary support apparatus comprises a flange bearing, the bearing portion of described flange bearing extend into main chain wheel 4 axis holes and supports described main chain wheel 4, and the flange part of described flange bearing is connected with casing 31 end bolt of driving axle box 3.
Working principle of the present utility model is: motor 1 drives retarder 2 and rotates, 21 of the output shafts of retarder 2 drive main chain wheel 4 and rotate, can move with 8 on the chain of main chain wheel 4 engagements, because main chain wheel 4 is not cantilevered being installed on the output shaft 21, but utilize spring bearing 7 to support main chain wheel 4, this support force is finally born by the casing 31 of driving axle box 3, therefore, the output shaft 21 of retarder 2 can not be subject to the cantilever pulling force, prolong the working life of retarder 2, and the precision of bend pipe also guarantees to some extent.
