Abstract
The utility model provides a zanjon ball and tapered roller combination bearing, includes deep groove ball bearing, interior clamping ring, outer clamping ring, inner split ring, outer spacer ring and tapered roller bearing. Two single -row tapered roller bearing and inner split ring, outer spacer ring constitute back -to -back formula and pair tapered roller bearing, and clamping ring, external pressure linkage connect in the rethread, constitute combination bearing with deep groove ball bearing. Because the mounted position has the close restraint, this is just high to a whole set of combination bearing's assembly to and deep groove ball bearing has the strict demand with tapered roller bearing internal diameter looks mutual deviation and external diameter looks mutual deviation. Combined bearing outer clamping ring be the step, avoided during operation and tapered roller bearing's holder to take place to interfere. The utility model discloses can enough bear the radial force, can bear certain axial force again, satisfy spatial position's needs moreover, easily installation, the precision is high, smooth operation, bearing long service life.
Description
Technical field
The utility model relates to bearing mnanufacture technical field, particularly relates to a kind of deep-groove ball and tapered roller combination bearing.
Background technique
At present, because combination bearing product structure is various informative, wide adaptability, installs the features such as simple and easy, is more and more adopted.In field of petroleum exploitation, extensive employing be controlled pressure drilling technology, this proposes certain requirement with regard to needing to the bearing on well head pressure control device, except bearing except radial force, also to bear certain axial force, and have strict restriction to the space mounting position of bearing.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of can bearing to bear certain axial load while high radial load very much, and the deep-groove ball of meeting spatial mounting point and tapered roller combination bearing.
The technological scheme adopted is:
A kind of deep-groove ball and tapered roller combination bearing, comprise deep groove ball bearing, inner pressure ring, outer press ring, inner split ring, outer spacer ring and tapered roller bearing.Described tapered roller bearing is two, and two back-to-back settings of tapered roller bearing, are provided with inner split ring between two tapered roller bearings and are connected with outer spacer ring, forms back-to-back formula matched cone roller bearing.Described deep groove ball bearing is connected on the tapered roller bearing of back-to-back formula pairing side by inner pressure ring, outer press ring, forms combination bearing with deep groove ball bearing.
Outer press ring in above-mentioned combination bearing is step type, when can avoid work and the retainer of tapered roller bearing interfere.
The utility model has following advantages:
1. the utility model adopts back-to-back formula matched cone roller bearing, and point of action is far away, good rigidly.
2. the utility model can bear certain axial load while high radial load very much bearing, and rotating speed is high.
3. the utility model outer press ring have employed staircase structural model, when avoiding work and tapered roller bearing retainer interfere.
4. the utility model inner pressure ring, outer press ring, inner split ring and outer spacer ring all adopt quenching with Subsequent tempering, and intensity is higher, improve the rub proofness to both sides deep groove ball bearing and tapered roller bearing, thus improve the working life of combination bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of deep-groove ball and tapered roller combination bearing, comprise deep groove ball bearing 1, inner pressure ring 2, outer press ring 3, inner split ring 4, outer spacer ring 5 and tapered roller bearing 6.Described tapered roller bearing 6 is two, two back-to-back settings of tapered roller bearing 6, is provided with inner split ring 4 and is connected with outer spacer ring 5 between two tapered roller bearings 6, forms back-to-back formula matched cone roller bearing.Described deep groove ball bearing 1 is connected on the tapered roller bearing of back-to-back formula pairing side by inner pressure ring 2, outer press ring 3, forms combination bearing with deep groove ball bearing.Outer press ring 3 in described combination bearing is step type, when can avoid work and the retainer of tapered roller bearing interfere.For ensureing a whole set of bearing accuracy, all to strictly control deep groove ball bearing and tapered roller bearing internal diameter phase mutual deviation and external diameter phase mutual deviation.Combination bearing decapacitation is born outside radial force, can also bear axial force, and the axial internal clearance of matched cone roller bearing is less than the axial internal clearance of deep groove ball bearing, bears thrust load mainly through tapered roller bearing.Outer press ring described in combination bearing is step type, when avoiding work and the retainer of tapered roller bearing interfere.Because inner pressure ring, outer press ring, inner split ring and outer spacer ring do not stress, its dimension of inner and outer diameters relevant to installation is slightly compacter than bearing dimension of inner and outer diameters, makes all to keep certain interval with axle and bearing support.Due to the restriction of bearing space mounting point, this just requires tight especially to a whole set of bearing assemble high tolerance range.
Claims (2)
1. a deep-groove ball and tapered roller combination bearing, comprise deep groove ball bearing (1), inner pressure ring (2), outer press ring (3), inner split ring (4), outer spacer ring (5) and tapered roller bearing (6), it is characterized in that described tapered roller bearing (6) is two, the back-to-back setting of two tapered roller bearings (6), be provided with inner split ring (4) between two tapered roller bearings (6) to be connected with outer spacer ring (5), form back-to-back formula matched cone roller bearing; Described deep groove ball bearing (1) is connected on the tapered roller bearing of back-to-back formula pairing side by inner pressure ring (2), outer press ring (3), forms combination bearing with deep groove ball bearing.
2. a kind of deep-groove ball according to claim 1 and tapered roller combination bearing, is characterized in that the outer press ring (3) in described combination bearing is step type.
