Embodiment Construction

[0050] Figure 1A is a side view of the support disk base 1 . Its inner area forms a hub shape, while the base body 1 with the hole 2 can be pushed or pressed onto the shaft. Grooves 3 , 4 , 5 , 6 , 7 are formed in the axial direction on the outer circumference of the base body 1 . The grooves 3 , 4 , 5 , 6 , 7 shown on the base body 1 represent the actual axial grooves of various embodiments as best examples here, these grooves have different cross-sectional shapes and in the circumferential direction There are different spacings. like in Figure 1B Shown in section, a support ring 8 is mounted on the outer circumference of the base body 1, after which the shaft of the spinning rotor of the spinning machine is spread out in a known manner.

[0051] exist Figure 1A Among them, the outer circumferential section of the base body 1 indicated by a is provided with an axial groove 3 with a hexagonal cross section. The sides of the hexagon are open towards the outer circumferen...

Abstract

The invention relates to a support disc and a support base for supporting the rotor of an open-end spinning device, wherein a support ring with a reasonable shape is fixedly installed on the outer circumference of the base of the support disc. According to the invention, a plurality of axially extending grooves are provided on the outer circumference of the base body of the support disk. When mounting the support disk on the base body, the grooves increase the adhesion of the support ring that is inserted later in order to counteract the centrifugal forces that occur. In addition, a method of producing such a support disk base is also provided.

Description

technical field [0001] The invention relates to a support disc base body for supporting a support disc of a rotor of an open-end spinning device, in which a support ring of rational shape is attached to the outer circumference of the support disc base body. Background technique [0002] In a known support disc (DE 41 36 794 A1), the base body of the support disc consists of two parts: an inner hub ring and a hub with a carrier ring clipped on the hub. On the outer circumference of the carrier ring there is a T-shaped projection running through the circumference, which T-shaped projection is subsequently surrounded by the carrier ring part mounted on the carrier ring. When the support disc is inserted, a high centrifugal force is exerted on the support ring while the ends of the support ring are clamped around the raised T-shaped ends, thus providing a support against the centrifugal force. In order to further improve the support body, some spaced holes are provided on the c...
