The specific embodiment
Core of the present utility model provides a kind of screw shaft, and this screw shaft can reduce the maintenance cost of conveyor screw, shortens the maintenance time of conveyor screw.Another core of the present utility model provides a kind of conveyor screw with above-mentioned screw shaft.
In order to make those skilled in the art understand the technical scheme that the utility model provides better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the screw shaft that the utility model embodiment provides is used for papermaking or wood-based plate manufacturing, and it comprises axle drive shaft 11, middle part axle 14 and tailing axle 18, and blade 15 is arranged on the middle part axle 14, one end and the axle drive shaft 11 of middle part axle 14 removably connect, and the other end and tailing axle 18 removably connect.Particularly, middle part axle 14 can be hollow shaft, and axle drive shaft 11 and tailing axle 18 then can be set with and be connected in the two ends of middle part axle 14 by bolt, make axle drive shaft 11 and tailing axle 18 be fixed on the middle part axle 14.Axle drive shaft 11 is connected with actuating device, and axle drive shaft 11 and tailing axle 18 rotate with respect to the casing of conveyor screw.
During the work of above-mentioned screw shaft, axle drive shaft 11 drives middle part axle 14 and rotates under the propulsive effort of actuating device, makes blade 15 apply application force, the conveying of realization material to material.During this screw shaft work, situations such as the wearing and tearing that take place according to middle part axle 14, axle drive shaft 11 and tailing axle 18 or fracture, changing corresponding part targetedly gets final product, content described in the background technology, keeping in repair this screw shaft makes and need not to change whole axle, and then reduced the maintenance cost of conveyor screw, shortened the maintenance time of conveyor screw.
During concrete enforcement, middle part axle 14 also can be connected by the first flange group with axle drive shaft 11, this first flange group comprises first flange of fixing with axle drive shaft 11 12 and second flange of fixing with middle part axle 14 13, first flange 12 and second flange 13 so just can be fixed together middle part axle 14, axle drive shaft 11 and tailing axle 18 by the bolt relative fixed.This scheme is born application force between middle part axle 14 and the axle drive shaft 11 by the first flange group, and then has reduced the possibility that middle part axle and axle drive shaft 11 generations are ruptured.Simultaneously, with respect to by bolt with above-mentioned three's ways of connecting, the above-mentioned first flange group can improve the Joint strenght of whole screw shaft, increases the transferable moment of screw shaft.Particularly, first flange 12 can weld with the end face of axle drive shaft 11, and second flange 13 is socketed on axle 14 inside, middle part.
In like manner, middle part axle 14 is connected by the second flange group with tailing axle 18, this second flange group comprises the 3rd flange of fixing with tailing axle 18 17 and the 4th flange of fixing with middle part axle 14 16, the 3rd flange 17 can weld with the end face of tailing axle 18, and the 4th flange 16 is socketed on axle 14 inside, middle part.Can strengthen above-mentioned technique effect by such scheme.
Further in the technical scheme, first flange 12 and axle drive shaft 11 hot chargings and welding, during concrete enforcement, realize the socket of first flange 12 and axle drive shaft 11 by the mode of hot charging, be arranged so that so first flange 12 is compacter with being connected of axle drive shaft 11, both Joint strenghts are higher simultaneously.In like manner, the 3rd flange 17 also can be connected by the mode of hot charging and welding with tailing axle 18.
Further in the technical scheme, in the screw shaft that the utility model embodiment provides, an end of middle part axle 14 is connected with the mode of second flange 13 by boring plug welding behind the hot charging.With respect to the mode that connects second flange 13 and middle part axle 14 by a plurality of bolts, such scheme makes that by the mode of hot charging the internal action power between axle 14 and second flange 13 of middle part is bigger, thereby both Joint strenghts have been improved, mode by plug welding then makes both Joint strenghts further promote again, transmits bigger moment with this.In like manner, also the other end of middle part axle 14 can be connected with 16 plug weldings of the 4th flange.
In the optimized technical scheme, one in first flange 12 and second flange 13 is provided with first shoulder, and both are by the first shoulder free-running fit, that is, at the first shoulder place, first flange 12 and second flange 13 adopt the mode of suit.When axle drive shaft 11 and middle part axle 14 are installed, carry out Primary Location by above-mentioned first shoulder, further adjust the position of first flange 12 and second flange 13 then, guarantee the right alignment of axle drive shaft 11 and middle part axle 14 with this.In like manner, one in the 3rd flange 17 and the 4th flange 16 is provided with second shoulder, and both are by the second shoulder free-running fit, to reach the purpose of the right alignment that guarantees middle part axle 14 and tailing axle 18.
The conveyor screw that the utility model embodiment provides comprises casing and is installed on the interior screw shaft of casing that this screw shaft is the described screw shaft of above-mentioned arbitrary scheme.Because above-mentioned screw shaft has above-mentioned technique effect, the conveyor screw with this screw shaft also should have corresponding technique effect, repeats no more herein.
More than screw shaft provided by the utility model and conveyor screw are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
