Definitions
- the invention relates to a shaft system for use in a chuck of a winding head, with at least one drive or output shaft and at least one axis or further shaft, which is arranged coaxially to the drive or output shaft, wherein at least one of these components designed as a hollow shaft or hollow shaft and in which the other component is at least partially received and supported relative to the hollow shaft or hollow axle by means of at least one bearing.
- the invention further relates to a chuck for winding heads of spinning machine and a winding head of a spinning machine and a spinning plants for synthetic fibers with such a shaft system.
- Shaft systems of the type discussed here such as those used in a chuck of a winding head for a synthetic fiber spinning machine, usually have deep groove ball bearings, roller bearings and / or spindle bearings for supporting the drive or output shaft.
- a generic shaft system is known, in which the local spool shaft is supported by means of deep groove ball bearings against an axis with housing function, wherein the axis is arranged coaxially to the spool shaft.
- the axle is designed as a hollow axle, in which the spool shaft is at least partially received.
- the invention has for its object to provide a shaft system with the features mentioned, which despite its limited space in the radial direction has a high radial load capacity and its storage is relatively inexpensive. Furthermore, a corresponding chuck for a spinning machine and a winding head with such a chuck to be proposed.
- the shaft system according to the invention is particularly suitable for use in a chuck of a spinning machine winding head, in particular a high-speed winding head, as used, for example, in spinning devices for man-made fiber production.
- the shaft system has at least one drive or output shaft and at least one axis or further shaft, which is arranged coaxially with respect to the drive or output shaft.
- at least one of these components is designed as a hollow shaft or hollow axle and at least partially accommodated in the other component and is supported relative to the hollow shaft or hollow axle by means of at least one bearing.
- Such an arrangement of the drive or output shaft relative to the axle or further shaft is in the sense of Invention referred to as a nested wave arrangement or nested Wellensys- system.
- the at least one bearing is designed as a ball roller bearing.
- the storage of the shaft system has a significantly higher load capacity in the radial direction than the previously used bearings, so that a shaft system with relatively high rigidity can be realized.
- Due to the narrower rolling element of a ball roller bearing over the balls of a conventional ball bearing is more grease space available at the same bearing width, so that the grease life of such storage is significantly extended, especially in fast-rotating nested shaft systems.
- the use of ball roller bearings of the same size allows the realization of radially loaded shaft systems or, if the load is the same, a so-called downsizing of existing structures.
- a machine element which serves for the forwarding of rotational movements and torques and for the storage of rotating parts.
- an axle is understood to mean a machine element which serves for carrying and supporting rotatable components. Unlike the shaft, however, the axle does not transmit torque.
- the ball roller bearing has a one-piece cage for the ball rollers.
- the shaft system is particularly suitable for high speeds.
- the cage should be designed as a steel cage, as this cage is particularly stable and thus far a further measure to improve the storage, especially at particularly high speeds, is realized.
- the ball roller bearing has a snap cage for the ball rollers.
- the snap cage made of a suitable plastic, such as polyamide.
- the ball roller bearing is arranged radially inwardly on the outer circumference of the rotatable shaft and radially outwardly on the inner circumference of a stationary axle.
- the ball roller bearing has a contact angle between about 5 ° and about 30 °. As a result, a high degree of smoothness of the drive or output shaft to be stored is realized.
- the ball roller bearing should have a pressure angle of about 15 °. As a result, an operation of the shaft system can be realized with very high smoothness.
- An improvement of the smoothness also aims the embodiment of the invention, according to which the ball roller bearing is axially biased.
- the shaft system is exposed to the highest radial loads, it makes sense that the ball roller bearing is multi-row, for example, two rows, is formed.
- the ball roller bearing is formed without a separate inner ring, and that the respective radially inwardly arranged respective track for the ball rollers on the radially inner rotatable shaft is arranged.
- the ball roller bearings in X- or O-arrangement to each other. This measure also aims to withstand forces acting on the shaft system in the radial and axial direction, so that the shaft system has sufficient life even with such a stress. It is advisable that the ball roller bearings form a support bearing with respect to the drive or output shaft. As a result, the axial play of the bearing can be set or adjusted accordingly to ensure optimum function.
- the ball roller bearings are arranged in a fixed-floating bearing.
- the hollow shaft or hollow shaft is supported by means of damping elements against a radially outer hollow cylindrical holding axis
- the shaft system according to the invention is preferably part of a chuck.
- the chuck is a component of a winding head of spinning machines, preferably a high-speed winding head for the manmade fiber production.
- a winding head is preferably used in spinning plants for the manufacture of man-made fibers.
- Figure 1 shows a possible embodiment of a nested shaft system with a ball roller bearing in a schematic longitudinal sectional view
- Figure 2a an alternative ball roller bearing for use in the
- FIG. 2b shows another alternative ball roller bearing for use in the shaft system according to FIG. 1
- FIG 3 shows a chuck of a winding head of a spinning machine with a nested shaft system according to Figure 1 in plan view.
- Figure 1 shows a schematic representation of a so-called nested wave system 100 having a central output shaft 1, which is rotatably connected at its one end to an output element 2, such as a socket.
- the shaft system 100 also has a stationary axle 3 in the manner of a carrier bush, which is arranged coaxially to the output shaft 1 and the output shaft 1 receives at least partially coaxially in the axial direction.
- the shaft system 100 has at least two roller bearings 4, 5, which are arranged in the axial direction at a distance from each other, are supported with their outer circumference against the axle or support bushing 3 and wear the output shaft 1 with its inner circumference.
- the carrier bush 3 is supported radially on the outside via elastomeric damping elements 6 against a further non-rotatable shaft 7, which is arranged coaxially to the output shaft 1.
- the non-rotatable shaft 7 is formed as a hollow shaft and surrounds the carrier bushing 3 coaxially.
- the non-rotatable shaft 7 is preferably arranged fixed to the housing and performs a holding function for the carrier bushing 3.
- the non-rotatable axle 3 or carrier bush and the axle 7 are preferably arranged stationary.
- the roller bearings 4, 5 are each formed as ball roller bearings.
- the ball roller bearings 4, 5 form a support bearing for the output shaft 1.
- the ball roller bearings 4, 5 are formed in a single row.
- the ball roller bearings 4, 5 can also be designed in two rows, with the ball rollers 8 of the one Row to the ball rollers 9 of the other row at the same pressure angle (Figure 2a) or the ball rollers 10 of a row to the ball rollers 11 of the other row in the opposite pressure angle ( Figure 2b) can be arranged to each other.
- the shaft system 100 can be realized according to an alternative embodiment in the X or O arrangement of the ball roller bearings.
- FIG. 3 shows a possible installation example of the shaft system 100 according to FIG. 1.
- the shaft system 100 is part of a chuck 110 of a spinning machine winding head 120.
- Such spinning machines are used, for example, for man-made fiber production and enable take-up speeds of up to 8000 meters per minute.
- the winding heads are so-called high-speed winding heads, in which the chuck is a fast-rotating rotor system, which undergoes considerable weight gain during winding.
- the winding head 120 a plurality of coils 130 are arranged one behind the other in the axial direction and rotatably coupled to the output element 2, so that the coils 130 are driven via the output shaft 1 and the output element 2.
