Description

Technical Field

[0001] The present invention belongs to the technical field of bearings, and specifically relates to a lightweight one-way bearing that can effectively reduce the weight of the one-way bearing without affecting the strength of power conduction, and can achieve the effects of easy processing and cost reduction in manufacturing, and relates to a one-way bearing.

Background Art

[0002] Generally seen one-way bearings, as shown in FIGS. 1 and 2, the one-way bearing 10 is used between an input member 20 and an output member 30, and the input member 20 can selectively drive the output member 30 in one direction by using the one-way bearing 10. Among them, the one-way bearing 10 includes a conduction ring seat body 11, and the conduction ring seat body 11 is provided with a plurality of accommodation grooves 12 formed at equal intervals corresponding to the peripheral edge of the input member 20. Shallow groove portions 121 and deep groove portions 122 are respectively provided at both ends of the inner bottom surface of the plurality of accommodation grooves 12. Rollers 15 are installed in the plurality of accommodation grooves 12. Further, an elastic member 16 is provided between the plurality of accommodation grooves 12 and the deep groove portions 122 opposite to the rollers 15. The plurality of rollers 15 can be held to be pressed toward the positions of the plurality of shallow groove portions 121 most quickly to generate one-way drive, and a plurality of semi-circular bar grooves 18 are provided at equal intervals on the outer edge portion of the conduction ring seat body 11, and a regulating action is generated on the output member 30 in combination with a plurality of positioning pins 19.

[0003] The aforementioned existing one-way bearing 10 has a single-member structure. In order not to affect the resistance during conduction, processing is carried out on the conduction ring seat 11, and it is necessary to incorporate the plurality of rollers 15. Moreover, in order to generate the conduction force with respect to the output member 30 by directly contacting the plurality of rollers 15 with the input member 20, the strength of the conduction ring seat 11 of the one-way bearing 10 to withstand the resistance must be increased. In order to prevent its fracture or rupture, the thickness of the conduction ring seat 11 must be increased, which increases the overall weight and processing difficulty in an invisible form, making it not in line with the trend of lightweight design. In addition, the one-way bearing 10 uses the plurality of small-diameter semi-circular bar grooves 18 and the plurality of positioning pins 19 to produce a regulating effect on the output member 30, but it is difficult to continuously receive force and continue to conduct and output. If used for a long time, it may lead to the fracture of the plurality of positioning pins 19 and the rupture of the conduction ring seat 11, affecting its service life.

[0004] That is, the existing one-way bearing is not perfect in terms of structural design and has problems such as insufficient weight reduction and insufficient force that can be received. Therefore, there is still a need for improvement, and the problem of how to improve the above problems is the subject of the present invention.

Best Mode for Carrying Out the Invention

[0015] As shown in FIGS. 3, 4, and 5, the one-way bearing 50 of the present invention is used between an input member 80 and an output member 90. The one-way bearing 50 is composed of a plastic mounting seat body 60, a plurality of rollers 65, and a metal conduction seat body 70. The input member 80 can selectively operate the output member 90 and operate it in one direction on the driving side.

[0016] As shown in FIGS. 3, 4, and 5, the detailed configuration of the one-way bearing 50 is such that the plastic mounting seat body 60 is formed by injection molding a plastic material. The plastic mounting seat body 60 is provided with a plurality of mounting grooves 61 penetrating in the radial direction at equal intervals, and the rollers 65 can be accommodated in the plurality of mounting grooves 61. Arc concave surfaces 62 corresponding to the peripheral edges of the plurality of rollers 65 are respectively formed on the opposite inner wall surfaces on both sides of the plurality of mounting grooves 61, increasing the operating space of the plurality of rollers 65. Further, among the inner wall surfaces on both sides of the plurality of mounting grooves 61, step grooves 63 are formed on the inner wall surface corresponding to the side where the plurality of rollers 65 do not perform a pressing operation, and elastic members 66 that can abut against the outer edges of the corresponding rollers 65 can be respectively accommodated. Further, a first braking arc surface 64 is formed on the side of the inner wall surfaces on both sides of the plurality of mounting grooves 61 of the plastic mounting seat body 60 opposite to the metal conduction seat body 70. By coupling, the plastic mounting seat body 60 and the metal conduction seat body 70 are positionally regulated. The input member 80 is installed on the side of the plastic mounting seat body 60 where there is no metal conduction seat body 70, and the input member 80 can be brought into contact with the plurality of rollers 65 in the plastic mounting seat body 60 and driven.

[0017] In addition, the metal conductive seat body 70 is manufactured from a metal material with resistance, and the metal conductive seat body 70 can be installed outside or inside the plastic mounting seat body 60. In the present invention, the main embodiment is that the metal conductive seat body 70 is installed outside the plastic mounting seat body 60, and the input member 80 is installed inside the plastic mounting seat body 60. Further, a plurality of conductive inclined surfaces 71 corresponding to the plurality of mounting grooves 61 are formed at the peripheral edge of the surface corresponding to the plastic mounting seat body 60 on the metal conductive seat body 70. As shown in FIG. 5, a deep groove portion 72 is formed at one end corresponding to the non-driving side among both ends of the plurality of conductive inclined surfaces 71, and a shallow groove portion 73 is formed at one end corresponding to the driving side. When the input member 80 operates and the plurality of rollers 65 move to the plurality of shallow groove portions 73 of the plurality of conductive inclined surfaces 71, a pressing drive action is generated (see FIG. 6). On the contrary, when the input member 80 moves the plurality of rollers 65 to the plurality of deep groove portions 72 of the plurality of conductive inclined surfaces 71, an idling action can be generated (see FIG. 5). Further, between the plurality of shallow groove portions 73 and the plurality of deep groove portions 72 of the plurality of adjacent conductive inclined surfaces 71 of the metal conductive seat body 70, second braking arc surfaces 74 corresponding to the first braking arc surface 64 of the plastic mounting seat body 60 are respectively formed, and the metal conductive seat body 70 and the plastic mounting seat body 60 are positionally regulated by the connection. Furthermore, at least one first engaging surface 75 is formed at the peripheral edge of the metal conductive seat body 70 corresponding to the output member 90, and a second engaging surface 95 corresponding to the first engaging surface 75 is formed at the opposite peripheral edge of the output member 90, so that the output member 90 can be driven synchronously with the metal conductive seat body 70, and the resistance area between the metal conductive seat body 70 and the output member 90 can be increased.

[0018] Thereby, the plurality of rollers 65 are used to selectively press the metal conductive seat body 70 in one direction against the plastic mounting seat body 60, and an action of driving the output member 90 in one direction through the one-way bearing 50 against the input member 80 is generated, so that a lightweight and damage-resistant one-way bearing can be configured.

[0019] During the actual operation of the one-way bearing of the present invention, as shown in FIGS. 5 and 6, when the input member 80 rotates toward the non-driving side (such as stationary or clockwise), the plurality of rollers 65 on the plastic mounting seat 60 of the one-way bearing 50 are located on one side of the plurality of deep groove portions 72 of the plurality of conductive inclined surfaces 71 of the metal conductive seat 70. The plastic mounting seat 60 does not move the metal conductive seat 70 through the plurality of rollers 65, and an idle rotation is formed between the input member 80 and the output member 90.

[0020] When the input member 80 rotates toward the driving side (such as counterclockwise), the plurality of rollers 65 on the plastic mounting seat 60 are driven synchronously, and the plurality of rollers 65 are moved to the plurality of shallow groove portions 73 opposite to the plurality of conductive inclined surfaces 71 of the metal conductive seat 70. The input member 80 and the plurality of conductive inclined surfaces 71 of the metal conductive seat 70 are opposed to sandwich and compress the plurality of rollers 65, and the input member 80 can drive the output member 90 in one direction through the one-way bearing 50.

[0021] As described in the above design and explanation, in the one-way bearing of the present invention, the plurality of mounting grooves 61 penetrating in the radial direction at equal intervals are formed in the plastic mounting seat 60, and the rollers 65 are respectively accommodated in the plurality of mounting grooves 61. The metal conductive seat 70 is provided with a plurality of conductive inclined surfaces 71 corresponding to the plurality of mounting grooves 61 on the surface corresponding to the peripheral portion of the plastic mounting seat 60. The plurality of rollers 65 on the plastic mounting seat 60 can utilize the opposing metal conductive seat 70 to generate a driving action in one direction. By using a plastic material for the plastic mounting seat 60, the weight is reduced, and at the same time, the area of the resistance strength is increased through the plurality of first engaging surfaces 75 of the metal conductive seat 70, making it difficult to cause fracture or rupture, effectively extending the service life, and effectively achieving the purpose of weight reduction without affecting the strength of power transmission. In addition, it is easy to process, suppresses the manufacturing cost, and can greatly improve its practicality.
