Abstract
The utility model discloses a kind of caterpillar-tractor winding displacement large pressuring roller, including rotating shaft and sleeve.Sleeve is arranged in the middle part of the rotating shaft, is welded and fixed between the rotating shaft and sleeve, the two ends of the rotating shaft are assembling end, the sleeve attenuates toward assembling end to both sides are stepped, it is described it is stepped be three section ladders.The utility model has the characteristics of simple in construction, service life is long.
Description
Technical field
The utility model is related to mechanical production devices field, more particularly, is big on a kind of caterpillar-tractor winding displacement
Pressure roller.
Background technology
Caterpillar-tractor is indispensable equipment in plastic pipe manufacturing process, and it can draw drive plastic pipe
Different processing are carried out by multiple production equipments, the speed of production and processing is improved, and then improve the production efficiency of tubing, when
When plastic pipe wall is very thin, during the pressure that the pressure of cylinder can bear beyond tubing, tubing will be deformed or even is subject to crushing,
In addition, cylinder is difficult to ensure that each cylinder on sustained height when mounted, therefore, can arrive causes the unbalance stress of tubing
Even, most of crawler belts outsides are sawtooth design to cylinder pair now simultaneously, and the contact surface between crawler belt and tubing is smaller, crawler belt pair
Pressure between tubing is concentrated on the contact surface, easily causes pipe deformations, while contact surface is smaller, is carried out under same pressure
Speed with transmission tubing will be substantially big with contact area slowly.
When actual use, crawler belt need to be changed often, it would therefore be highly desirable to a kind of caterpillar-tractor winding displacement large pressuring roller, existing pressure
Roller when in use between one metaboly will occur long afterwards, it is necessary to regularly replace pressure roller or pressure roller is repaired, serious shadow
Efficiency and cost have been rung, it is necessary to improve.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art, applicant improves by repeatedly practice, devises a kind of crawling traction
Machine winding displacement large pressuring roller, simple in construction, service life is long.
Technical scheme：In order to realize foregoing invention purpose, the technical scheme that the utility model is used for：A kind of crawler belt is led
Draw machine winding displacement large pressuring roller, including rotating shaft and sleeve.Sleeve is arranged in the middle part of the rotating shaft, welds solid between the rotating shaft and sleeve
Fixed, the two ends of the rotating shaft are assembling end, and the sleeve attenuates toward assembling end to both sides are stepped, it is described it is stepped be three sections
Ladder.
Further, sleeve described in the utility model is stainless steel sleeve, and the surface of the stainless steel sleeve sets anti-
Rusty scale.
Yet further, the utility model is further defined, and the rotating shaft is High wear-resistant steel, and the rotating shaft surface is set
Put chromium coating.
Further, the length of pressure roller described in the utility model is 1.9m, and the length sleeve of the pressure roller is 1.5m.
Beneficial effect：Compared with prior art, its advantage is the utility model：
1st, the utility model sets assembling end at the two ends of rotating shaft, and usage is prompted by the mark for assembling end.
2nd, rotating shaft described in the utility model is High wear-resistant steel, and the rotating shaft surface sets chromium coating, turns so as to extend
The service life of axle, and be unlikely to deform during use.
Brief description of the drawings
Fig. 1 is a kind of structural representation of caterpillar-tractor winding displacement large pressuring roller.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection of the present utility model
Scope is not limited to the embodiment.
As shown in figure 1, a kind of caterpillar-tractor winding displacement large pressuring roller, including rotating shaft 1 and sleeve 2.
The middle part of the rotating shaft 1 is arranged sleeve 2, is welded and fixed between the rotating shaft 1 and sleeve 2, the two ends of the rotating shaft 1
For assembling end 3, the sleeve 2 toward assembling end 3 attenuate to both sides are stepped, it is described it is stepped be three section ladders.
The sleeve 2 is stainless steel sleeve 2, and the surface of the stainless steel sleeve 2 sets antirust coat.
The rotating shaft 1 is High wear-resistant steel, and the surface of rotating shaft 1 sets chromium coating.
The length of the rotating shaft 1 is 1.9m, and the length of sleeve 2 is 1.5m.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
