All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
FIG. 1 is a schematic illustration of a locking structure for a right angle contact bearing according to an embodiment of the present invention. As shown in fig. 1, an angular contact bearing locking structure according to an embodiment of the present invention includes: the shaft 1, the angular contact ball bearing 5 that overlaps on the shaft 1 is used for fixed angular contact ball bearing 5's bearing frame 6 to and the backing ring 2. The mounting manner of the angular ball bearings 5 can be selectively determined according to the actual situation, for example, two angular ball bearings 5 mounted back-to-back or face-to-face can be sleeved on the shaft 1.
As shown in fig. 2, the outer peripheral surface of the shaft 1 is provided with a first axial chute 11 extending in the axial direction of the shaft 1, and a first circumferential chute 12 provided in the extending direction of the first axial chute 11 and communicating with the first axial chute 11; a first bulge 13 is formed between two adjacent first axial sliding grooves 11 and a first circumferential sliding groove 12 between the two adjacent first axial sliding grooves;
as shown in fig. 3, the outer ring of the retainer ring 2 abuts at least a part of the end face of the angular ball bearing 5; the inner ring of the retainer ring 2 is provided with a second circumferential runner 21 extending inward from an end of the retainer ring 2, and a second circumferential runner 22 provided in an extending direction of the second circumferential runner 21 and communicating with the second circumferential runner 21; a second protrusion 23 is formed between two adjacent second axial sliding grooves 21 and a second circumferential sliding groove 22 between the two second axial sliding grooves;
the second protrusion 23 is slidable into the shaft 1 in the extending direction of the first axial chute 11 and rotatable relative to the shaft 1 along the first circumferential chute 12 to be engaged with the first protrusion 13.
In the embodiment of the invention, the grooves on the shaft 1 (including the first axial sliding groove 11 and the first circumferential sliding groove 12) are complementary to the grooves on the baffle ring 2 (including the second axial sliding groove 21 and the second circumferential sliding groove 22). During assembly, the second protrusions 23 on the baffle ring 2 slide into the shaft 1 along the grooves of the first axial sliding grooves 11 on the outer peripheral surface of the shaft 1, and then rotate along the first circumferential sliding grooves 12 communicated with the first axial sliding grooves 11, so that the second protrusions 23 in the baffle ring 2 are aligned with the first protrusions 13 on the shaft 1 to be clamped, and the clamping connection of the baffle ring 2 and the shaft 1 is realized. The invention effectively realizes the purpose of reducing the axial dimension by adopting a blocking ring locking mode with a complementary groove, and does not need to turn threads on a shaft, thereby avoiding the reduction of the strength of the shaft due to the turning of the threads, and having simple and easy structure and convenient and time-saving assembly and adjustment.
In some embodiments, each first axial runner 11 communicates with one first circumferential runner 12, and no communication exists between two adjacent first circumferential runners 12. For example, two first axial sliding grooves 11 extending along the axial direction of the shaft 1 are arranged on the shaft 1, a first circumferential sliding groove 12 extending along the circumferential direction of the shaft 1 from the extending end of each first axial sliding groove 11 is arranged at the extending end of each first axial sliding groove 11, an L-shaped structure is formed between each first axial sliding groove 11 and each first circumferential sliding groove 12, and the corresponding first circumferential sliding grooves 12 of the two first circumferential sliding grooves 12 are not communicated. In this way, the structure of the shaft 1 reduced by the grooving can be reduced, and the reduction in strength of the shaft itself due to the grooving can be reduced.
In other embodiments, any two adjacent first circumferential runners 12 communicate with each other. For example, the shaft 1 is provided with three first axial sliding grooves 11 extending along the axial direction of the shaft 1, the extending end of each first axial sliding groove 11 is provided with a first circumferential sliding groove 12 extending along the circumferential direction of the shaft 1 from the extending end of the first axial sliding groove 11, and an L-shaped structure is formed between the first axial sliding groove 11 and the first circumferential sliding groove 12. The first circumferential sliding grooves 12 corresponding to the three first circumferential sliding grooves 12 are connected and communicated together in an end-to-end mode to form an annular groove. In this way, the rotation angle range of the baffle ring 2 relative to the shaft 1 can be improved, and the processing, the assembly and the disassembly are convenient.
The baffle ring 2 can be provided with a threaded hole 24; the angular contact bearing locking structure may further include: the adjustment screw 4 corresponding to each screw hole 24 is inserted through the screw hole 24 and then the adjustment screw 4 abuts against the end face of the angular ball bearing 5. The pretightening force of the angular contact ball bearing 5 can be adjusted by adjusting the screwing depth of the adjusting screw 4, thereby achieving the purposes of locking the angular contact ball bearing and improving the rotation precision of the shafting. The number of the threaded holes 24 on the baffle ring 2 can be selectively determined according to practical situations, for example, 2, 3, 6, etc. are arranged. In an alternative embodiment, the baffle ring 2 is provided with at least two threaded holes 24, and the at least two threaded holes 24 are uniformly distributed along the circumferential direction of the baffle ring 2. Adopt a plurality of screw holes, the pretightning force of the angular contact ball bearing 5 of being convenient for accurate adjustment, a plurality of screw holes evenly distributed can improve angular contact ball bearing 5's pretightning force distribution homogeneity.
Fig. 4 is a schematic structural view of an anti-loose wave plate in an embodiment of the present invention. In an alternative embodiment, the angular contact bearing locking structure may further include: a locking wave plate 3 is arranged between each adjusting screw 4 and the baffle ring 2. The anti-loose wave plate 3 is arranged, so that the contact tightness between the adjusting screw 4 and the baffle ring 2 can be improved.
An exemplary angular contact bearing locking arrangement according to an embodiment of the present invention is described below with reference to fig. 5-10.
During assembly, the blocking ring 2 with the complementary groove is first slid in along the groove of the shaft 1. Specifically, the second protrusions 23 on the retainer ring 2 slide into the shaft 1 along the grooves of the first axial sliding grooves 11 on the outer peripheral surface of the shaft 1, as shown in fig. 5 and 6.
Then, the retainer ring 2 is rotated in the extending direction of the first circumferential runner 12 communicating with the first axial runner 11, so that the second projection 23 in the retainer ring 2 is caught in alignment with the first projection 13 on the shaft 1, and the catching of the retainer ring 2 with the shaft 1 is achieved, as shown in fig. 7 and 8.
Then, 6 adjusting screws 4 with anti-loose wave plates 3 are installed at the positions of 6 threaded holes 214 of the baffle ring 2, and the pretightening force of the angular contact ball bearing 5 is adjusted by adjusting the screwing depth of the 6 adjusting screws 4, so that the purpose of locking the bearing and improving the rotation precision of the shafting is achieved, as shown in fig. 9 and 10.
The first axial chute 11 on the shaft 1 may extend from the end of the shaft 1 into the shaft 1, and may extend in the axial direction or at an angle to the axial direction from other positions on the outer peripheral surface of the shaft 1. When the first axial sliding groove 11 on the shaft 1 extends from other positions on the outer peripheral surface of the shaft 1 along the axial direction or forms a certain angle with the axial direction, the locking structure of the angular contact bearing can realize the locking of the non-shaft-end angular contact ball bearing.
In summary, the locking of the angular contact ball bearing is realized by adopting the baffle ring with the complementary groove, the shaft, the screw and the anti-loose wave plate, and the structure shortens the axial dimension and avoids the weakening of the strength of the shaft due to the processing of the screw thread.
