Bearings are one of the indispensable components in today's major machinery. For different functions and actuators, there are different types of bearings, which are mainly installed between the shaft and the base, and use the positioning of the bearings. Provides the function of relative motion, so that the shaft can rotate smoothly on the base; however, the user who knows the bearing on the market also knows that its alias is also called Palin. The variety of bearings is quite difficult to classify. Now it is a one-way bearing that is common on the market and belongs to the special purpose classification of bearings.

Generally, the one-way bearing used in the market has the function of anti-reverse transmission, so it is widely used in power machines such as bicycles, and its structure is composed of a collar (inner and outer rings), a rotating body (balls, springs), and The structure of the retainer is mainly composed of two sets of rings, and a plurality of rotating bodies are installed and kept at a distance to avoid mutual contact, and the retainer maintains a smooth rolling, thereby when the one-way bearing is rotating forward, As a single-direction transmission; if the one-way bearing rotates in the opposite direction, it will form an idling state, and its function is to prevent the unintended reverse rotation of the one-way bearing, and also to avoid the work object from reversing or carding when there is no power source. Living and causing injuries or mechanical damage.

Please refer to the Republic of China Patent Bulletin No. M398579 "One-way bearing knot a plurality of rolling bodies are disposed on an outer ring body and a ring gear to cause relative movement between the outer ring body and the ring gear; the ring gear, the plurality of balls and the plurality of elastic bodies form a latching device, The ring gear is disposed in the receiving groove of the outer ring body, and the plurality of balls and the plurality of elastic bodies are respectively disposed in the plurality of perforations of the outer ring body; when the ring gear is rotated in one direction by the original moving member, A plurality of spheres are clamped in a plurality of slots provided in the ring gear to produce a transmission follower effect; if the original member drives the ring gear to rotate in the opposite direction, the bevel is caused by a bevel of the slot to push the ball It will only be idling, so it will not have the effect of transmitting power; therefore, the above simple components make the creation easy to assemble, not easy to lock, high service life and high torque.

The above-mentioned "unidirectional bearing structure" is the shaft commonly used in the market today. One of the bearings, although effectively providing the smoothness of the shaft and the base of the stable machine in the mutual rotation, and achieving the advantages of simple assembly, cost reduction, volume reduction, and increased torque and service life, The structure is more complicated, which makes the maintenance work extremely laborious, and the details of the parts are too large, so the cost and weight of the whole bearing are too high compared with the general bearing. Therefore, the relevant industry must further think about how to improve, in order to meet the user's use. .

In order to explain in a preferred embodiment, and not to make any shape for this creation. Limitation of the formula, as shown in the first to fourth figures, a bearing structure is provided, which comprises: an outer ring shell 1 having a set of holes 11 at a central position thereof; and an inner ring member 2 A plurality of holes 21 are formed in the group hole 11 and disposed at a central position. The inner ring member 2 is provided with a plurality of limit sliding holes 22 on one side of the inner wall of the group hole 11 , and the limit sliding holes 22 are respectively The slanting assembly 3 is provided with a swaying assembly 3, and the slewing assembly 3 includes a spring 31 and a ball 32. The ball 32 is mounted in the limiting sliding hole 22, and the ball 32 is mounted in the limiting sliding hole 22. One end of the spring 31 is elastically biased against the hole wall of the limit sliding hole 22, and the other end is biased against the ball 32, and the elastic load is used to drive the resetting of the ball 32; a brake member 4 is mounted on the sleeve of the inner ring member 2 twenty one.

The foregoing is the main technical feature of the present invention, which corresponds to the content of the first item of the patent application scope of the present application, and the purpose and implementation of the present invention are known in detail, and the technical features described in the remaining subsidiary patent scopes are The detailed description or additional technical features of the first content of the patent application scope, and not to limit the scope of the first paragraph of the patent application scope, it should be noted that the first item of the patent application scope of the present application does not necessarily include the scope of the remaining subsidiary patents. Technical characteristics.

Before the operation of the present invention is described, the second embodiment is further described in the second figure. The inner ring member 2 is annular in design and is disposed on the inner ring member. Each of the limiting slide holes 22 of the two-week side penetrates the inner ring member 2 and has an open opening on both sides. Each of the limit sliding holes 22 further includes a large diameter section 221 and a connecting end of the large diameter section 221 The small diameter section 222 and one of the other ends of the large diameter section 221 The large-diameter section 221 is embedded in the groove 223, and the spring 31 is inserted into the recessed groove 223, and one end of the spring 31 corresponding to the ball 32 is exposed to the inset groove 223 and is biased against the ball 32. 2 the length corresponding to one side of the outer ring shell 1 to the side corresponding to the brake member 4 is greater than the length of the small diameter section 222 from the side of the inner ring member 2 corresponding to the outer ring shell 1 to the side corresponding to the brake member 4, and The small diameter section 222 is designed to be tapered from one end to the other end of the large diameter section 221; in addition, the opening of the small diameter section 222 corresponding to the outer ring shell 1 is formed by connecting one end of the large diameter section 221 to the other end. After being gradually expanded and tapered, the limit sliding holes 22 are designed in such a manner that the balls 32 can be stably restrained inside, and when the braking member 4 rotates and the inner ring member 2 rotates, the balls 32 can be reliably displaced and rolled by the braking members. 4 is clamped to the outer ring shell 1 or is in a state of rotation.

In addition, please continue to refer to the second figure. In addition to the design of the limit slide hole 22 to provide smooth movement of the ball 32 in the rolling displacement, the design of the outer ring shell 1 and the brake member 4 also increases the rolling of the ball 32. The smoothness of the displacement and the tightness of the clamping ball 32, the inner wall surface of the group of holes 11 of the outer ring shell 1 is further surrounded by a main arc groove 111, and the braking member 4 corresponds to the side of the limiting sliding hole 22. A pair of arc grooves 41 are provided around the recess. By the arrangement of the main arc grooves 111 and the auxiliary arc grooves 41, the balls 32 can be more reliably determined in rolling displacement, and the outer ring shell 1 and the brake member 4 are clamped against the balls 32. When the braking member 4 and the inner ring member 2 are rotated in the forward direction, the rotation of the outer ring casing 1 can be stably driven.

Continuing the above description, in the design of the brake member 4, in order to reliably interlock the rotation of the inner ring member 2, the design of the brake member 4 is hexagonal or twelve-angled, and the inner ring member 2 is The sleeve hole 21 is also designed in the same shape as the shape of the brake member 4. Please refer to the second figure (the design of the shape of the brake device 4 is preferably a hexagonal type and a twelve-corner type, but it is not It is used to limit the number of sides of the brake member 4 and the sleeve hole 21, and may also be a design of a common multiple of two and three, for example, an eighteen-sided type, etc., which mainly corresponds to the multiple of the two sides, and the three The side of the multiple is formed by one of three points. The heart point is designed by the common multiple of two and three, so that the inner ring member 2 can be surely and stably interlocked by the action of the brake member 4, and the figure is illustrated by a hexagonal embodiment.

Referring to the fifth figure, when the present invention is mounted on the shaft and is operated in the forward direction, the brake member 4 will rotate together with the inner ring member 2 due to the hexagonal design, and the brake member 4 will be driven in the forward direction. When the ring member 2 rotates, the ball 32 will roll in the opposite direction due to the rotation of the brake member 4, and will be displaced in the opposite direction to the position of the spring 31. When the brake member 4 and the inner ring member 2 are opposite to each other, the outer ring shell 1 When the rotation is continued in the forward direction, the ball 32 is moved from the large diameter section 221 to the small diameter section 222. At this time, the distance between the braking member 4 and the outer ring housing 1 is narrowed by the width of the limiting sliding hole 22, so The ball 32 is gradually changed by the distance and is tightly fitted in the space between the main arc groove 111 and the sub-arc groove 41, and the outer ring case 1 is further rotated in synchronization.

In contrast, in the sixth figure, when the braking member 4 interlocks the inner ring member 2 to rotate in the reverse direction, the balls 32 located in the limiting sliding hole 22 roll in a forward direction and are displaced toward the set position of the spring 31. When the ball 32 is displaced to the large diameter section 221, the clamping relationship between the brake member 4 and the outer ring casing 1 is released, and the ball 32 is only rotated by the brake member 4 in the limit sliding hole 22, and does not rotate. Will be in contact with the outer ring shell 1, at this time only the brake member 4 drives the reverse rotation of the inner ring member 2, which is commonly referred to as the idling state. After the above-described forward and reverse actuation, the setting of the swaying assembly 3 not only stabilizes the stability of the bearing in the forward direction, but also reduces the weight and maintenance problems caused by too many parts. It can increase the torque when it is used.

In addition, it is worth mentioning that the design of the main arc groove 111 and the auxiliary arc groove 41 can also be designed in a semi-arc shape according to the shape of the ball 32, and can also be designed in a semi-rectangular shape. As shown in the seventh figure, the design of the primary arc slot 111 and the secondary arc slot 41 is mainly to provide a clip between the ball 32 and the brake member 4 and the outer ring shell 1 when the forward movement is mainly provided. The tightness is achieved by the increase of the clamping area to stabilize the forward movement, so as to avoid the situation where the prior art is easily detached due to the insufficient area of the clamping, which will cause the mechanical stagnation in operation, and serious Problems such as the twisting of the shaft occur, so the creation of this method achieves the advantages of being lighter in weight, easier to maintain, and lower in cost. In addition, when one end of the spring 31 is biased against the ball 32, the ball 32 can be arbitrarily moved in the limit sliding hole 22, and hits the inner ring member 2 and the outer ring shell 1, thereby generating foreign matter such as debris and dust. The operation of the integral bearing is affected, and the spring 31 is surrounded by a coil and is matched with the ball 32 in a spherical shape, so that the ball 32 can be firmly pressed against the end of the spring 31 to be rebounded and stabilized.

Referring to the eighth figure, the design of the inner ring member 2 can be formed in an integrally formed manner as shown in the second figure, and then the swaying assembly 3 is guided by the limit sliding hole 22. The inner ring member 2 can be assembled into a two-piece assembly, and the inner ring member 2 can be formed by a center along its circumference to form a left-right symmetry and equal size, and the inner ring member 2 is two pieces. The assembly method is convenient for the maintenance and replacement of the component 3 in the future.

The above description is only a preferred embodiment for explaining the present creation, and is not intended to impose any form limitation on the creation, so that any modification related to the creation in the same creative spirit is made. Or the changer, other types that can be implemented according to the same effect, should still be included in the scope of protection of this creative intention.

In summary, the "bearing structure" of this creation is practically and cost-effectively in line with the needs of industrial development, and the disclosed structural creation is also an unprecedented innovative structure, so it has "novelty" It should be undoubtedly considered that this creation can be more effective than the conventional structure. Therefore, it is also "progressive". It fully complies with the requirements of the application requirements for new patents in the Patent Law of China, and is a patent application in accordance with the law. Please check with the bureau for an early review and give it affirmation.
