Abstract
The invention relates to a special bearing for a rotor spinner, mainly used in the textile machinery, and belongs to the technical field of the textile machinery. The special bearing comprises an outer ring, ball rolling elements, a mandrel, a sealing ring and a retainer. The outer ring and the mandrel are respectively provided with a corresponding channel, two columns of ball rolling elements are uniformly distributed in the channels, the outer ring is connected with the mandrel through the ball rolling elements, the ball rolling elements are fixed through the retainer to form a whole assembly, the sealing ring is installed between the outer ring and the mandrel, and the sealing ring is fixed through the outer ring to form an integral body. The mandrel is provided with a step, and is also provided with a first oil injecting through hole and a second oil injecting through hole. Oil can be injected through the above oil injecting through holes, so the replacing time and cost can be saved; and the number of the ball rolling elements is increased, so the load of each of the ball rolling elements and the axial forces of an inner ring and the outer ring are reduced, the bearing capability of the special bearing for the rotor spinner is improved, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to a kind of steam flow Spinning Machinery special bearing, be mainly used in above the textile manufacturing machine, belong to the frame field of mechanical technique.
Background technique
Being used for the Spinning Machinery bearing mainly is made up of outer ring, inner ring, rolling element, retainer, seal ring, grease etc.Employing is installed rolling element between outer ring and inner ring, rolling element adopts spherical, is evenly distributed between outer ring and the inner ring, is fixed up with two retainers, and seal ring plays dustproof and prevents that leaking outside effect of grease, grease from playing the lubricated effect such as formation oil film that reaches.Former being assemblied in of this bearing needs two covers to install side by side on the textile manufacturing machine, be not suitable for bearing bigger load during work, changes inconvenience, influences the working life of working efficiency and bearing.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of steam flow Spinning Machinery special bearing is provided, saved replacing time and cost, increase work efficiency, prolong the working life of bearing.
According to technological scheme provided by the invention, a kind of steam flow Spinning Machinery special bearing comprises outer ring, ball rolling element, mandrel, seal ring and retainer etc.Be respectively equipped with corresponding raceway groove on described outer ring and the mandrel, two row ball rolling elements are evenly distributed in raceway groove inside, connect by the ball rolling element between outer ring, the mandrel, and by retainer fixedly the ball rolling element form the assembly parts of an integral body, described seal ring is installed between outer ring and the mandrel, described seal ring is fixed by the outer ring, thereby forms an integral body.
Further, be shaped on step above the described mandrel, and be provided with the first filling oil hole and the second filling oil hole.The described second filling oil hole and first is annotated, and oil hole is vertical to be arranged and is interconnected.
The present invention compares with original structure and has the following advantages:
Bearing structure of the present invention changes double row bearing into, two original covers is installed side by side transformed for an entire combination part, and the filling oil hole that mandrel is provided with can inject grease, has saved replacing time and cost; Increase ball rolling element quantity, thereby the axial force of the load that each ball rolling element is subjected to and Internal and external cycle reduces, and has improved the bearing capacity of steam flow Spinning Machinery special bearing, has prolonged the working life of bearing.
Description of drawings
Fig. 1 partly cuts open figure for structural representation of the present invention.
Fig. 2 is the structural representation sectional view of mandrel of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action by reference to the accompanying drawings is further described:
As depicted in figs. 1 and 2, the present invention includes outer ring 1, ball rolling element 2, mandrel 3, seal ring 4, retainer 5 etc., described outer ring 1 is respectively equipped with corresponding raceway groove with mandrel 3, two row ball rolling elements 2 are evenly distributed in raceway groove inside, connect by ball rolling element 2 between outer ring 1, the mandrel 3, and by the fixing assembly parts of an integral body of ball rolling element 2 formation of retainer 5, described seal ring 4 is installed between outer ring 1 and the mandrel 3, described seal ring 4 is fixing by outer ring 1, thereby forms an integral body.
This compound mode has strengthened the surface of contact of mandrel raceway groove and outer ring raceway, has improved the bearing capacity of steam flow Spinning Machinery special bearing, and increased the working life of Rotor spinning frames special bearing.
On mandrel 3, be shaped on step, and be provided with the first filling oil hole 6 and the second filling oil hole 7.The described second filling oil hole 7 and first is annotated, and oil hole 6 is vertical to be arranged and is interconnected.The first filling oil hole, 6 right-hand members are made tapped hole.
Can when grease is not enough, can add grease by the filling oil hole like this, increase the quantity of rolling element simultaneously, improve bearing because being subjected to axial force, on the other hand because the increase of rolling element can increase bearing capacity by more uniform bearing load.
The base dimension of described outer ring 1 and mandrel 3 is as follows: described outer ring 1 outside dimension is φ 72mm, and width dimensions is 46mm; Described outside diameter of mandrel is of a size of φ 46.8mm, and the step outside dimension is φ 40mm, and the mandrel width dimensions is 76mm, and mandrel 3 end faces are of a size of 49mm to step, and the little external diameter groove width of mandrel is of a size of 1.7mm, and external diameter is φ 37.5mm; The right-hand member tapped hole of the first filling oil hole 6 is M8 * 12; The left end bore dia of the second filling oil hole 7 and the first filling oil hole 6 is φ 3 mm.
The present invention has widened the width of outer ring 1, also the inner ring with former use is replaced as mandrel 3, is provided with the filling oil hole in the mandrel 3, and the tapped hole of its filling oil hole setting can supportingly arrange screw bolt or other threaded accessories, in order to the sealed oil-filling passage, prevent that grease from leaking.The present invention installs conversion for the assembly parts of an integral body side by side with two original cover bearings, and changed the shape of outer ring and inner ring, on mandrel, added the oiling through hole, increased the quantity of rolling element, strengthen the surface of contact of mandrel raceway groove and outer ring raceway, improved the bearing capacity of steam flow Spinning Machinery special bearing, prolonged the working life of Rotor spinning frames special bearing.
