Abstract
The utility model relates to a support bearing which comprises a bearing seat, wherein one side of the bearing seat is provided with an oil groove; an oil hole is formed inside the bearing seat corresponding to the oil groove; an outer ring and an inner ring which are matched with each other are arranged in the bearing seat; both ends of the outer ring and the inner ring are respectively provided with a seal ring; steel balls and rolling needles are arranged in the outer ring and the inner ring; each steel ball is provided with a steel ball holder; both ends of each rolling needle are respectively provided with a rolling needle holder; and the outer side of each rolling needle holder is provided with a retaining ring. By changing the traditional installation design of two bearings into one composition bearing, the utility model can avoid the early failure of the bearing, caused by the difference between different bearings, in the working process. Because of the integral bearing design, the lubrication of the bearing is improved, and lubricating grease can directly enter the working ball race through the oil groove of the outer ring and the oil hole.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of block bearing.
Background technique
The purposes of bearing is widely, and its form also is diversified.Form by two cover deep groove ball bearings as the bearing configuration on the existing Weaving device, separate with lining at the inner ring place of bearing.Two cover bearings are installed in the bearing support, and carry out axially locating and carry axial force with back-up ring.Oilhole is arranged on the bearing support, and repairing is by oilhole lubricating grease to be squeezed in the space during maintaining, enters in the bearing again.
Existing bearing is configured under the operating mode of general light load and can meets the demands, but along with the number of spindles of spinning frame strengthens, the machine lengthening, situation-F that the load of bearing obviously strengthens, the not competent work of bearing shows as the bearing beginning of fatigue failure.Its reason is: 1, bearing has born very large radial and axial combined loading at work, because textile industry, bearing is to work uninterruptedly, has caused the fatigue damage on bearing working surface and has caused bearing failure.2, bearing is a grease lubrication, lubricating grease is to enter two cavitys that overlap between the bearings by the oilhole on the bearing support, just can enter on the working surface of bearing then, like this for the working surface that makes bearing has enough lubricating grease, just must at first after filling up lubricating grease in the cavity, lubricating grease be entered in the bearing.Because in the bearing support full lubricating grease is arranged, lubricating grease is driven stirring and can be produced very big heat at work, the effect that influence is lubricated, and be easy to produce lubricated stuffing situation not in place, make bearing failure.3, owing to be the configuration of two cover bearings, therefore require the size of two cover bearings and the conformity of beating very high, and this is difficult to accomplish under actual conditions.Bearing inconsistent makes bearing carrying inequality at work, also is the reason of bearing premature failure.
The model utility content
The purpose of this utility model provides a kind of block bearing, in order to overcome the problems referred to above of prior art, can bear very big radial and axial power, and is lubricated convenient and reliable, and the block bearing of high conformity.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of block bearing, comprise bearing support, one side of bearing support has oil groove, the inside of bearing support and oil groove corresponding section are provided with oilhole, and the inside of bearing support is provided with outer ring and the inner ring that cooperatively interacts, and the two ends army of outer ring and inner ring is equipped with seal ring, the inside of outer ring and inner ring is provided with steel ball and needle roller, wherein steel ball is provided with ball retainer, and the two ends of needle roller are respectively equipped with cages for needle, and the outside of cages for needle is equipped with back-up ring.
The beneficial effects of the utility model are: the utility model is joined arm to the installation of existing two cover bearings and is designed to a cover combination bearing, has avoided because the early failue in the bearing working that the difference between the different bearings causes; Adopt the design that ball bearing bears axial force and needle bearing comes bearing radial force, utilized their work characteristics to satisfy the usage requirement of bearing well; Because whole design bearing also makes the lubricated of bearing be improved, the work raceway that lubricating grease can directly enter bearing by the oil groove and the oilhole of outer ring.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the sectional view of the described a kind of block bearing of the utility model embodiment.
Among the figure:
1, bearing support; 2, oil groove; 3, oilhole; 4, outer ring; 5, inner ring; 6, seal ring; 7, steel ball; 8, needle roller; 9, ball retainer; 10, back-up ring; 11, back-up ring.
Embodiment
As shown in Figure 1, the described a kind of block bearing of the utility model embodiment, comprise bearing support 1, one side of bearing support 1 has oil groove 2, the inside of bearing support 1 and oil groove 2 corresponding sections are provided with oilhole 3, the inside of bearing support 1 is provided with outer ring 4 and the inner ring 5 that cooperatively interacts, the two ends of outer ring 4 and inner ring 5 are equipped with seal ring 6, the inside of outer ring 4 and inner ring 5 is provided with steel ball 7 and needle roller 8, wherein steel ball 7 is provided with ball retainer 9, the two ends of needle roller 8 are respectively equipped with cages for needle 10, and the outside of cages for needle 10 is equipped with back-up ring 11.
The internal surface of bearing outer ring 4 is provided with two: the work raceway, and one is the circular arc raceway, and another is the lineal shape raceway, and corresponding bearing inner race 5 outer surfaces also have two raceways, and one is the circular arc raceway, another is the lineal shape raceway.In the middle of the circular arc raceway of inside and outside lasso, arrange one group of steel ball 7, steel ball 7 is evenly separated at 9 circumferencial directions by ball retainer: arrange one group of needle roller 8 in the middle of the lineal shape raceway of inside and outside lasso, needle roller 8 is separated equably by cages for needle, both sides at the lineal shape raceway of outer ring are provided with two back-up ring doors, in order to the axial dipole field of restriction needle roller and cages for needle.Near the endoporus both sides on planes seal groove is arranged at bearing outer ring 4, sheet seal ring 6 respectively is installed in seal groove, seal ring 6 plays the lubricating grease that prevents bearing inside and leaks and prevent the effect that outside dust or titbit enter bearing inside.Also be provided with oil groove 2 and oilhole 3 at bearing outer ring, can directly dose lubricating grease on the work raceway of bearing by oil groove 2 and oilhole 3.
