Abstract
The utility model relates to a special bearing for a steam flow spinner, and the special bearing is mainly used in textile machineries and belongs to the technical field of spinner machineries. The special bearing for the steam flow spinner comprises an outer ring, ball rolling elements, a mandrel, a seal ring, a retainer and the like, wherein channels are respectively and correspondingly arranged on the outer ring and the mandrel, two lines of ball rolling elements are uniformly distributed in the channels, the outer ring and the mandrel are connected through the ball rolling elements, the ball rolling elements are fixed through the retainer so as to form an integral assembly unit, the seal ring is installed between the outer ring and the mandrel, and the seal ring is fixed by the outer ring so as to form a whole; steps are arranged on the mandrel, and a first oil filling through hole and a second oil filling through hole are also arranged on the mandrel. Grease can be injected through the oil filling through holes, so that the replacing time and cost can be saved; the number of the ball rolling elements are increased, so that the load on each ball rolling element and the axial force of the inner ring and the outer ring are reduced, the bearing capacity of the special bearing for the steam flow spinner is improved, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of steam flow Spinning Machinery special bearing, is mainly used in above textile manufacturing machine, belongs to frame field of mechanical technique.
Background technique
For Spinning Machinery bearing, mainly by outer ring, inner ring, rolling element, retainer, seal ring, grease etc., formed.Employing is installed rolling element between outer ring and inner ring, and it is spherical that rolling element adopts, and is evenly distributed between outer ring and inner ring, with two retainers, is fixed up, and seal ring plays dustproof and prevents that leaking outside effect of grease, grease from playing and lubricate and the effect such as formation oil film.Former being assemblied on textile manufacturing machine of this bearing needs two covers to install side by side, is not suitable for bearing larger load during work, changes inconvenience, affects the working life of working efficiency and bearing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of steam flow Spinning Machinery special bearing is provided, and has saved replacing time and cost, increases work efficiency, and extends the working life of bearing.
The technological scheme providing according to the utility model, a kind of steam flow Spinning Machinery special bearing, comprises outer ring, ball rolling element, mandrel, seal ring and retainer etc.Described outer ring with on mandrel, be respectively equipped with corresponding raceway groove, two row ball rolling elements are evenly distributed in raceway groove inside, between outer ring, mandrel, by ball rolling element, connect, and by retainer fixedly ball rolling element form a whole assembly parts, described seal ring is arranged between outer ring and mandrel, described seal ring is fixed by outer ring, thereby forms an integral body.
Further, above described mandrel, be shaped with step, and be provided with the first filling oil hole and the second filling oil hole.Described the second filling oil hole and first is annotated, and oil hole is vertical to be arranged and is interconnected.
The utility model is compared and is had the following advantages with original structure:
The utility model bearing structure changes double row bearing into, makes two original covers install and transform for an entire combination part side by side, 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 subject to and Internal and external cycle reduces, and has improved the bearing capacity of steam flow Spinning Machinery special bearing, has extended the working life of bearing.
Accompanying drawing explanation
Fig. 1 is that figure is partly cutd open in structural representation of the present utility model.
Fig. 2 is the structural representation sectional view of mandrel of the present utility model.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As depicted in figs. 1 and 2, the utility model comprises 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, between outer ring 1, mandrel 3, by ball rolling element 2, connect, and by the fixing whole assembly parts of ball rolling element 2 formation of retainer 5, described seal ring 4 is arranged between outer ring 1 and 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 with step, and be provided with the first filling oil hole 6 and the second filling oil hole 7.Described the 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 filling oil hole like this, increase the quantity of rolling element simultaneously, improve bearing because being subject to axial force, the increase due to rolling element can increase bearing capacity by more uniform bearing load on the other hand.
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 outer diameter of step is of a size of φ 40mm, and 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 utility model has been widened the width of outer ring 1, also the inner ring of former use is replaced as to mandrel 3, is provided with filling oil hole in mandrel 3, the tapped hole of its filling oil hole setting can supportingly arrange screw bolt or other threaded accessories, in order to sealed oil-filling passage, prevent that grease from leaking.The utility model is installed two original cover bearings side by side and is transformed for a whole assembly parts, and changed the shape of outer ring and inner ring, on mandrel, added 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, extended the working life of Rotor spinning frames special bearing.
