Abstract
The utility model relates to a bearing, in particular to a two-direction thrust combined bearing, which comprises an upper shaft collar, a lower shaft collar and two sets of bearings formed by a pedestal ring positioned between the two shaft collars. The utility model is characterized in that a spherical aligning roller is arranged between one of the shaft collars and the pedestal ring. In the condition of no change of the outside measurement, the technical proposal can effectively enhance the carrying capacity of the bearing, and at the same time, due to adopting the albronze solid open retainer, the proposal is favorable for improving the strength and the wearing capacity of the retainer and enhances the lubricating property of the bearing; the volume of the retainer is lightened and the weight of the retainer is greatly reduced, thereby being favorable for improving the rotating flexibility of the bearing. The utility model has the advantages of high reliability, long service life and low cost.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of bidirectional propulsion combination bearing.
Background technique
Bidirectional angular contact thrust ball bearing, by two blowout patches up and down, forms at seat ring between two blowout patches and retainer and steel ball up and down, last blowout patche, angular contact thrust ball bearings are overlapped in blowout patche and seat ring formation two down.Because will being used for the carousel supports part of oil drilling machine, uses this class bearing, and the applied load of drilling equipment is big, service condition is disliked slightly, at present mainly there is the problem of the aspects such as greasy property difference of the big revolution flexibility that influences steel ball of lower, the closed retainer weight of the dynamic and static load of the end thrust of bearing, bearing in bidirectional angular contact thrust ball bearing, can't satisfy the needs of drilling equipment.
Summary of the invention
The purpose of this utility model provides a kind ofly to be compared with bidirectional angular contact thrust ball bearing, and bearing capacity height, greasy property are good, and has the bidirectional propulsion combination bearing of certain aligning effect.
The technical solution of the utility model is: a kind of bidirectional propulsion combination bearing, comprise up and down two blowout patches, at formed two groups of bearings of a seat ring between two blowout patches up and down, what it is characterized in that therein installing between a blowout patche and the seat ring is the spherical aligning roller.
Above-mentioned retainer is open retainer.
Above-mentioned open retainer is the aluminum bronze solid cage.
Characteristics of the present utility model are: 1, under the situation of profile size constancy, change the angular contact thrust ball bearing on top into the self-aligning thrust roller bearing structure, the angular contact thrust ball bearing of bottom is constant, in the time of in working order, can play certain aligning effect; 2, retainer adopts the Open architecture of aluminum bronze entity, helps improving the intensity and the wear resistance of retainer, has strengthened the greasy property of bearing, and the minimizing of the volume of retainer, and weight is alleviated greatly, helps improving the flexibility of revolution of bearing; 3, owing to change steel ball into the spherical aligning roller, bidirectional propulsion combination bearing of the present utility model is compared with original bidirectional angular contact thrust ball bearing, and bearing capacity improves nearly 80%.
Description of drawings
Accompanying drawing 1 is a sectional view of the present utility model;
Accompanying drawing 2 is the open retainer structural representation of the utility model;
Accompanying drawing 3 is the A-A sectional view of the utility model accompanying drawing 2.
Embodiment
As shown in Figure 1, 2, 3, the bidirectional propulsion combination bearing is by last blowout patche 1, seat ring 4, be installed in retainer 2, spherical aligning roller 3 and following blowout patche 7, seat ring 4 between blowout patche and the seat ring, be installed in down the two cover bearings up and down that retainer 5 between blowout patche and the seat ring, steel ball 6 form and combine, retainer 2 is open retainer.Because this model utility is guaranteeing under the constant and immovable situation of overall volume of boundary dimension, when being used for oil-well drilling equipment, do not increasing under the volume and weight situation of main frame, can bear higher load, the 5000m of drilling depth when using bidirectional angular contact thrust ball bearing are brought up to 9000 meters, have possessed high reliability, long lifetime, using effect cheaply.
Claims (3)
