Description

Technical Field

[0001] The utility model belongs to the technical field of one-way bearings, and in particular relates to a cylindrical roller wedge type one-way bearing. Background Art

[0002] One-way bearings are a special type of bearing that allows the shaft to rotate freely in only one direction, while locking the shaft in the other direction to prevent reverse motion. They are widely used in a variety of industrial sectors, including the automotive industry, where they are used in transmission systems such as automotive transmissions, clutches, and differentials to efficiently transmit and control torque, improving vehicle performance and reliability. The aerospace industry, where they are used in key components such as aircraft landing gear, flywheels, and aircraft engines to withstand high speeds and high temperatures. The machine tool industry, where they are used in spindles and feed systems to achieve high-precision motion control and stable operating conditions. And the textile machinery industry, where they are used in key components such as spinning machines, looms, and textile equipment to meet high-speed and high-precision operating requirements.

[0003] Load capacity is a key performance parameter of one-way bearings. Under high loads, one-way bearings are subject to shear forces, making the inner and outer rings susceptible to unseating. Furthermore, to achieve unidirectional motion, the bearings are often designed with separate rotating and locking components, further complicating the bearing structure. To address these issues, the present invention provides a cylindrical roller wedge-type one-way bearing. Utility Model Content

[0004] The purpose of the present utility model is to provide a cylindrical roller wedge type one-way bearing to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A cylindrical roller wedge-type one-way bearing comprises an inner ring and an outer ring, wherein a rotating component is provided between the inner ring and the outer ring, wherein the rotating component comprises a plurality of wedges, a plurality of rollers and a ring spring, wherein the plurality of wedges are arranged in an annular array around the inner ring, and the plurality of rollers are arranged in an annular array around the inner ring, the plurality of rollers and the plurality of wedges are evenly interspersed, and the ring spring simultaneously surrounds the plurality of rollers and the plurality of wedges.

[0007] Preferably, a plurality of planetary shafts are provided at the outer ring, and the planetary shafts are evenly distributed at the outer ring in a ring array.

[0008] Preferably, an annular groove is provided at the waist of the roller, and the annular spring is embedded in the annular groove.

[0009] Preferably, the wedge block is cylindrical as a whole, one side of the wedge block is a circular arc side wall, and the other side of the wedge block is a wavy side wall; the protrusion of one side of the wavy side wall is greater than the protrusion of the other side of the wavy side wall; a ring spring groove is provided at the waist position of the wavy side wall of the wedge block.

[0010] Preferably, a positioning notch is provided on the wavy side wall of the wedge block.

[0011] Preferably, a first limiting groove is provided on the outer wall of the inner ring, and a second limiting groove is provided on the inner wall of the outer ring; the rotating component is embedded in both the first limiting groove and the second limiting groove.

[0012] Preferably, the outer ring includes an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are riveted together to form the outer ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The utility model provides a cylindrical roller wedge-type one-way bearing, which adopts a ratchet-type wedge. The wedge can rotate while avoiding reverse rotation. The rotating structure and locking structure are integrated to simplify the bearing structure.

[0015] (2) The utility model provides a cylindrical roller wedge-type one-way bearing, which adopts a roller and wedge structure. Compared with the ball structure, the roller and wedge have a stronger load-bearing capacity, are not easy to fall off between the inner ring and the outer ring, and have better load performance;

[0016] (3) The utility model provides a cylindrical roller wedge type one-way bearing, which uses a ring spring to converge the rollers and wedges.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A cylindrical roller wedge-type one-way bearing comprises an inner ring 1 and an outer ring 2. A rotating component 3 is positioned between the inner and outer rings 1 and 2, enabling relative rotation between the two rings. A retaining groove 1 4 is provided on the outer wall of the inner ring 1, and a retaining groove 2 5 is provided on the inner wall of the outer ring 2. The rotating component 3 engages both retaining grooves 1 4 and 2 5. The cylindrical rotating component 3 secures the outer ring 2 and the inner ring 1, further stabilizing the connection between the two rings and preventing them from falling out, thereby improving load-bearing performance. To facilitate installation, the outer ring 2 includes an upper cover plate 15 and a lower cover plate 16. Furthermore, the rotating component 3 is secured by riveting the upper and lower cover plates 15 and 16 together, securing the rotating component 3 within the retaining grooves 1 4 and 5, ensuring the overall load-bearing performance of the bearing.

[0026] The rotating component 3 comprises fifteen wedges 6, three rollers 7, and a ring spring 8. The fifteen wedges 6 form a circular array tightly surrounding the inner ring 1, while the three rollers 7 form a circular array surrounding the inner ring 1, with the three rollers 7 evenly interspersed between the fifteen wedges 6. To ensure that the rollers 7 and wedges 6 only encircle the inner ring 1, the ring spring 8 simultaneously surrounds the rollers 7 and the wedges 6. An annular groove 9 is located at the waist of the rollers 7, into which the ring spring 8 fits. The wedge 6 is cylindrical in shape, with a circular sidewall 10 on one side and a wavy sidewall 11 on the other. The wavy sidewall 11 is more convex on one side than on the other side. This design ensures that the circularly arranged wedges 6 can rotate in only one direction. A ring spring groove 12 is located at the waist of the wavy sidewall 11 of the wedge 6, into which the ring spring 8 fits. The ring spring 8 is tightened to the wedge 6, and the presence of the ring spring 8 can make the fifteen wedges 6 keep rotating synchronously as far as possible. In order to facilitate installation and make the wedge 6 correctly assembled, a positioning notch 13 is provided at the wavy sidewall 11 of the wedge 6.

[0027] In order to facilitate the installation of the device, three planetary shafts 14 are provided at the outer ring 2 , and the planetary shafts 14 are evenly distributed at the outer ring 2 in a ring array.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
