Background technology
The spinning rotor of modern free-end spinning machine is worked in the mode of rotation at a high speed, and its per minute can change about 100000min at present
-1On most free-end spinning machines, spinning rotor is installed in the rotor subject by means of a kind of special long double row ball bearing apart from ball distance ring that has.Inner ball distance ring is arranged on the axostylus axostyle of spinning rotor, and simultaneously, outside ball distance ring is arranged in the cavity of the axle sleeve that forms the external shaft carrier ring.
The external shaft carrier ring with respect to the main body of spinning rotor by means of various springs and damping element and install with elastic type.
For example according to CZ238202, CZ248192, CZ248820, CZ249724, CZ256305, CZ265584, CZ266602, CZ272096, CZ278878, CZ285560, DE102004007758, the installation that the common structure feature of many solutions is external shaft carrier rings in further tubular sleeve, tubular sleeve are generally the turn of rectangular cross sectional profile and are installed in the cavity of spinning rotor main body by means of various near their ends.Yet further tubular sleeve has increased production cost and the gross weight that is installed in the spinning rotor in the bearing uncomfortablely.
According to the solution of CZ248824, by means of the tubular body of making by elastomeric material the bearing of spinning rotor is installed, the length of tubular body is corresponding with the length of external shaft carrier ring, and possesses on its end the axle collar is arranged.These axle collars are between between spring support, and the tubular middle portion of main body is divided and only had influence on spring support minimum level.This elastic component part also can increase the gross weight that is installed in the spinning rotor in the bearing, and in addition, the shape of the relative complex of the elastic component of this compactness derives from the production and cost is higher in price.
According to CZ17947U1, flexible member is made for the elastic annular thing.On their inner surface, be provided with the annulus projection, it is meshed with corresponding ring groove, and ring groove is located on the outer surface of the known double-row bearing outer ring in the support of spinning rotor.Externally the rough shape of the formation of bearer ring upper groove and elastic annular thing has increased the expense of installing.
The purpose of the technical program is to provide a kind of support, and from the viewpoint of cost and functional aspect, it will overcome the defective in the background technology.New solution should satisfy the requirement in identical service life of the expectation of bearing self and its spring support as much as possible.Integral unit formula carriage spring support is always done as a whole and is replaced, without any risk, and for example its bearing portions undue wear.
Summary of the invention
The purpose of the technical program is the identical service life that reaches the expectation of bearing self and its spring support as far as possible.This purpose is that the spring support by a kind of spinning rotor of the free-end spinning machine of realizing by means of double row ball bearing reaches, the interior ball distance ring of double row ball bearing is arranged in the axostylus axostyle of spinning rotor spaced reciprocally, and outer ball bearing circle is spaced apart and arranged in the surrounding jacket with cylindrical outer surface separately, simultaneously, the surrounding jacket in the cavity of the main body of spinning unit is by means of being positioned near two annular, resilient, member its tail end and installed.The principle of the technical program is that it is installed in the cavity of spinning unit main body by means of two annular, resilient, member, and its principle is that elastic component is connected with the outer surface of non-removable mode with the external shaft carrier ring on internal diameter.
This solution is cheaply, because it does not need to form axle sleeve to form any element for its shape is connected with elastic component on the surface of bearer ring externally.The non-removable feature of assembly has been guaranteed that bearing shaft is enclosed within and has been stablized fasteningly in the elastic component, and guaranteed that after elastic component or bearing self have damaged it always does as a whole the replacement.This makes and a new bearing can not be installed in the damaged elastic component that vice versa.
If the internal diameter of elastic component is connected by means of the mode of cohering with the outer surface of outer bearing axle sleeve, then also be favourable; And consider the characteristic of modern glue, this means low cost and the non-removable quality that is connected.
If near the elastic component that is positioned at the spinning rotor can have bigger elastic deformation amount than near the elastic component the free end of the axostylus axostyle that is positioned at spinning rotor, then also is favourable.
Because near the elevated pressures of the end of the bearing the known rotating band of spinning rotor, different rigidity is desirable in the support.
Can preferably realize the performance of different distortion amount of two elastic components of same size, thereby make that the elastic modelling quantity that is positioned near the elastic component material the spinning rotor is lower than near the elastic modelling quantity of the material of the elastic component the axostylus axostyle free end that is positioned at spinning rotor.The equal length of elastic component increases their quantity-produced possibilities.
Can also realize the performance of different distortion amount, thereby make, two elastic components all use identical materials, are positioned near the spinning rotor elastic component and have the littler section modulus of section modulus than near the flexible member of the elastic component the axostylus axostyle free end that is positioned at spinning rotor.Preferably, the flexible member that is positioned near the elastic component the spinning rotor has the shorter length of length than near the flexible member of the elastic component the axostylus axostyle free end that is positioned at spinning rotor.This solution is fit to consider the uniformity of elastomeric material.
If elastic component comprises inside and outside tubular portion, and these parts all are coaxial and interconnect by means of a beam that tangentially extends in inner tubular part, and, the adjacent anchor ring surface of following between inside and outside tubular portion with the end of double row ball bearing is sealed, and then also is favourable in this case.Therefore, the space between elastic component is sealed in the dustproof mode, and simultaneously, the tangential beam of use diverse location and/or shape can reach the different elastic deformation amounts of two elastic components.
