Abstract
The invention discloses a cast aluminum paper leading rope pulley device for papermaking machinery, which comprises a paper leading rope pulley main body, a bearing and a fastening bolt. The paper leading rope pulley main body consists of a pulley edge, a spoke and a hub; the paper leading rope pulley main body has a cast aluminum structure; a position fixedly sleeved with the bearing in the hub is ductile cast iron; and the ductile cast iron is fixed in the hub, and the cast aluminium is one-step molding. The embodiment can effectively prevent deformation, lighten weight, save materials and energy and improve paper leading precision.
Description
Technical field
The present invention relates to a kind of leading rope pulley device, particularly a kind of cast aluminum paper leading rope pulley device for papermaking machinery.
Background technology
Paper machinery is when new start of paper machine or the disconnected paper with leading rope pulley device, and the guiding carrier rope is drawn to paper in a kind of devices that draw paper such as drying cylinder, paper carrying roll, sizing applicator, calender.More than 100 this device will be arranged on the paper machine.All the time, papermaking equipment adopts steel welding construction with leading rope pulley device more both at home and abroad, and papermaking equipment steel welding construction leading rope pulley device is big, yielding owing to weight, and result of use is not good.In addition, reasons such as steel welding construction leading rope pulley device welding produce distortion, directly influence paper injection efficient and produce paper quality, because the steel welding construction leading rope pulley device of distortion easily paper is drawn partially or paper is torn, cause the paper injection failure and the paper injection again of having to.Under high speed of a motor vehicle high-quality required, the problem of steel welding construction leading rope pulley device was particularly outstanding.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of cast aluminum paper leading rope pulley device for papermaking machinery, and this cast aluminum paper leading rope pulley device for papermaking machinery can effectively prevent distortion, weight reduction, saving material and the energy and improve the paper injection precision.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of cast aluminum paper leading rope pulley device for papermaking machinery; Comprise leading rope pulley main body, bearing and fastening bolt, the leading rope pulley main body is made up of wheel rim, spoke and wheel hub, and the leading rope pulley main body is the cast aluminium structure; Position with the solid socket of bearing in the wheel hub is a spheroidal graphite cast-iron, and spheroidal graphite cast-iron is fixed in the wheel hub; The cast aluminium structure is one-shot forming.
Further technical scheme of the present invention is:
Spheroidal graphite cast-iron is QT500-7.
The angle towards the drying cylinder end face that spoke radial centre lines and axis form is an acute angle.
The invention has the beneficial effects as follows: adopt alloy cast aluminium leading rope pulley material of main part, more reasonable structure; Position with the solid socket of bearing in the wheel hub is spheroidal graphite cast-iron QT500-7, and material property is good, and intensity is higher, and its wall thickness reduces, and manufacturing cost reduces, and weight reduces; The one-shot forming of cast aluminium material of main part casting technique has overcome the shortcoming of steel welding construction modification, has improved paper injection precision and efficient.
Description of drawings
Fig. 1 is a sketch map of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Embodiment: a kind of cast aluminum paper leading rope pulley device for papermaking machinery; Comprise leading rope pulley main body, bearing 4 and fastening bolt; The leading rope pulley main body is made up of wheel rim 1, spoke 2 and wheel hub 3, and the leading rope pulley main body is the cast aluminium structure, like this axial width of wheel rim original attenuation; Position with the solid socket of bearing in the wheel hub is a spheroidal graphite cast-iron, and spheroidal graphite cast-iron is fixed in the wheel hub, and intensity is high like this; High-strength alloy cast aluminium structure is one-shot forming.
Spheroidal graphite cast-iron is QT500-7.
The angle towards the drying cylinder end face that spoke radial centre lines and axis form is an acute angle, can make wheel rim be positioned as close to the drying cylinder end face like this.
