Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a one-way clutch bearing, and more particularly to a one-way clutch bearing having a reverse rotation function by using a position adjuster of a bearing holder.

[0002]

[Prior art]

 Generally, a one-way clutch bearing functions as a bearing when rotating in either direction, and when trying to reverse, the outer peripheral side and the inner peripheral side of the bearing are fixed to each other and function as a clutch. One-way clutch bearings are widely used as members that fulfill these functions, such as office equipment, daily necessities such as fishing reels, and parts for industrial machinery.

[0003]

[Problems to be solved by the device]

 However, for example, when it becomes necessary to reversely rotate a rotating shaft such as a sleeve fitted in a one-way clutch bearing when repairing office equipment, conventionally, the device is disassembled and the one-way clutch bearing is slid. It is extremely inconvenient because it cannot be reversed unless the work such as removing it from the plug is performed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a one-way clutch bearing which can make a reverse rotation possible by using a position adjusting tool of a bearing holder. There is.

[0005]

[Means for Solving the Problems]

 The one-way clutch bearing of the present invention to achieve the above object has a plurality of notches for moving the bearing formed on the inner wall of the bearing cover of the one-way latch bearing, and a notch for positioning the holder at the upper part of the bearing cover. The bearing cover is fitted with a bearing holder provided with a large number of roller accommodating parts and support springs, the rollers in contact with the moving notches are accommodated in the respective roller accommodating parts, and the upper surface of the bearing holder is A protrusion that engages with the holder positioning notch is formed, and the engagement between the protrusion and the holder positioning notch is released to move the relative position of the bearing cover and the bearing holder. The feature is that it is equipped with an adjusting tool.

[0006]

[Action]

 In such a one-way clutch bearing, when the holder positioning notch of the bearing cover and the protrusion of the bearing holder that are engaged with each other by the adjusting tool are disengaged, the bearing holder moves relative to the bearing cover. It becomes possible to rotate. When the bearing holder is rotated with respect to the bearing cover, the roller accommodated in the roller holder of the bearing holder is moved relative to the notch for movement of the bearing cover that abuts against this roller, and the gap between the roller and the sleeve. The contact pressure of changes. This changes the one-way clutch bearing from the one-way clutch state to the un-clutch state or vice versa.

【Example】

 Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional exploded perspective view showing a one-way clutch bearing of this embodiment. 2 is a partial vertical sectional view showing the one-way clutch bearing, and FIG. 3 is a plan view showing a partial cross section thereof. Further, FIG. 4 is a partial cross-sectional plan view showing a state in which the position of the bearing holder is moved.

As shown in FIG. 1, the one-way clutch bearing has a bearing cover 1, and an inner wall 1 a of the bearing cover 1 has a notch 2 for movement that allows movement of a roller 7 of a bearing described later. Are formed in plural. Further, holder positioning notches 3 which are rectangular recesses are formed at predetermined intervals on the upper end of the bearing cover 1.

As shown in the drawing, a bearing holder 4 having a plurality of roller accommodating portions 5 is mounted on the bearing cover 1 having such a shape, and each roller accommodating portion 5 has a roller 7 Is housed. Further, each roller accommodating portion 5 is equipped with a support spring 6 that elastically contacts the outer peripheral portion of the roller 7 to support the roller 7. On the other hand, on the peripheral portion of the upper end surface of the bearing holder 4, protrusions 4a are formed at predetermined intervals. By engaging the protrusion 4a with the holder positioning notch 3 of the bearing cover 1, the bearing cover 1 and the bearing holder 4 are positioned relative to each other. Further, an adjusting tool 8 used when adjusting the relative positions of the bearing cover 1 and the bearing holder 4 is formed on the upper end surface of the bearing holder. 1, 3 and 4, reference numeral "9" is a reference numeral for a guide guide piece of a bearing, which will be described later, and reference numeral "10" is a sleeve for rotating relative to the bearing cover 1a. It is the code | symbol shown.

Next, the operation of the one-way clutch bearing configured as described above will be described. In office equipment, fishing reels, or certain industrial equipment, which can rotate only in one direction and require a function to prevent reverse rotation by clutch operation, in order to obtain such a function, one-way The use of clutch bearings is as described above.

The roller 7 of the bearing is accommodated in a state in which it is contained by a moving notch 2 formed in the inner wall 1 a of the bearing cover 1 and a roller accommodating portion 5 formed in the bearing holder 4. When rotating in one direction, it is supported rotatably on the surface on the rotating side and functions as a roller of the bearing. Further, at the time of reverse rotation, the roller 7 comes into contact with the surface of the moving notch 2 of the inner wall 1a of the bearing cover 1 in sliding contact with the guide protrusion 9 formed inside the bearing holder 4 and is located inside the bearing. Pressed to 10. That is, at the time of reverse rotation, the sleeve 10 comes into close contact with the roller 7, the rolling of the roller 7 is prevented, and the sleeve enters the clutch state.

With the reverse rotation thus prevented, the engagement between the bearing holder 4 and the holder positioning notch 3 formed in the bearing cover 1 is released using the adjusting tool 8 of the bearing holder 4. When the bearing holder 4 is moved by a predetermined angle, the rollers 7 accommodated in the roller accommodating portion 5 of the bearing holder 4 move inward along the bearing guide protrusions 9 of the bearing holder 4 and come into close contact with the sleeve 10. It is released from the state. As a result, the clutch is disengaged, and the sleeve 10 is in the reverse rotatable state.

Further, the roller 7 accommodated in the roller accommodating portion 5 in the bearing holder 4 is pressed toward the inner side where the clutch operation of the bearing holder 4 is performed by the support spring 6 that adjusts the elasticity. It is supported smoothly and securely in a stable state.

Further, the support spring 6 is attached to the bearing holder 4 of the one-way clutch bearing, and the adjusting tool 8 used for adjusting the position of the roller 7 accommodated in the bearing cover 1 is attached to the upper surface of the bearing holder 4. As a result, the one-way clutch bearing can be rotated in the reverse direction, and when repairing office equipment, fishing reels, industrial machinery, etc., or when reverse rotation is required, it is possible to disassemble the equipment that uses the one-way clutch bearing. It is possible to reverse the rotation axis of the sleeve, etc.

As described above, the one-way clutch bearing, which functions as a bearing when rotating in one direction and functions as a clutch that blocks rotation when rotating in the reverse direction, can be rotated in the reverse direction by changing the position of the bearing holder. The invention facilitates the reversing work that occurs during repair and reverse adjustment, and is extremely useful industrially.

[0016]

As described above, according to the present invention, by operating the adjusting tool, it is possible to rotate the rotary shaft such as the sleeve in the direction in which the clutch cannot be rotated in the reverse direction. Therefore, it is possible to easily perform the reversing work of the rotary shaft that occurs during the repair or the reversing adjustment.
