Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a one-way clutch/bearing integrated assembly structure used in a rotating shaft portion in which a one-way clutch and a bearing are necessarily used at the same time.

[Conventional technology]

Generally, when clutches and bearings are used in various industrial machines, they are often manufactured independently and as separate products, and depending on the machine, they may be installed adjacent to each other.

Conventionally, especially when the two are installed so close that they can be combined into one, it is either necessary to install the two, which are independent from each other, close to each other, or to design the main parts of the two as one unit. Special parts formed as one piece are used. An example of the latter is shown in FIG.

In the example shown in FIG. 5, the outer rings 1' and 2' of the bearing and the one-way clutch are joined by a joining member 3', and the inner ring 3'' is a common part and is formed as an integral part.

[The problem that the idea aims to solve]

However, if the bearing and the clutch are made up of separate and independent parts, it will take a lot of man-hours to assemble them into the device, making it impossible to reduce assembly costs.Also, since the bearings and clutches are made up of separate parts, the shape of the area around the mounting part may not be easy to assemble. It is necessary to take measures such as providing a special space for the mounting part, which results in problems such as the dimensions of the mounting part becoming large and the cost of materials not being saved.

In the example shown in Figure 5, since it is an integral part, it is easy to assemble it into the device, and it is possible to save space, but the part is not versatile and is very expensive unless mass produced. It becomes expensive. Furthermore, since the bearing and the inner ring of the clutch are shared, there is a problem in that even if friction occurs in the bearing, the bearing cannot be easily replaced.

This invention solves the problems of conventional bearings and clutches that are installed adjacent to each other or are integrated into one, and
The object of the present invention is to provide a one-way clutch/bearing integrated structure in which the bearing and the clutch are connected by a connecting ring made of resin or metal using the seal grooves of the clutch.

[Means to solve the problem]

Therefore, as a means to solve the above-mentioned problems, this invention proposes a bearing that rotationally supports the load of the rotating shaft and has a sealing groove or a connecting groove on at least one side of the bearing, and a bearing that supports the rotation of the rotating shaft in one direction. A one-way clutch consisting of a one-way clutch that transmits transmission only to the one-way clutch and has a sealing groove or connecting groove on at least one side of the clutch, and a connecting ring that fits into the sealing groove or connecting groove of both sides and connects them together.
The structure of the bearing is an integral assembly structure.

The connecting ring may be made of resin or metal, or may be made of other materials as long as they have elasticity necessary for connection. At least two protrusions are formed on both ends of the connecting ring. Alternatively, it may have a U-shaped cross section.
This protrusion or U-shaped cross section is forcibly fitted into a sealing groove or connecting groove on one side of the bearing and the one-way clutch, respectively, thereby connecting the one-way clutch and the bearing together.

[Effect]

In the one-way clutch/bearing integral assembly structure of the above configuration based on this invention, as described above, both sides of the connecting ring are forcefully press-fitted into the seal grooves of the one-way clutch/bearing, thereby making the two strong. Can be connected.

In this case, the two are connected by the connecting ring using a sealing groove or the like and a fitting force or frictional force. Therefore, the cross section of the connecting ring does not have to have a protrusion, and even if it has a U-shaped cross section, it is sufficient that the two can be fitted together.

The connecting ring of this integrally assembled structure, which connects the two together in this way, (1) can be easily connected by simply pushing the bearing and clutch outer ring from both sides, and (2) has a structure that fits both the bearing and the clutch. It is extremely versatile in that it has two sides, making it easy to assemble, and (3) has a function to prevent roller movement.

〔Example〕

Embodiments of this invention will be described below with reference to the attached drawings.

Figure 1 shows a one-way clutch based on this invention.
The main cross-sectional view of the integral assembly structure of the bearing is shown, and the second

As shown, bearing 1 is connected to one-way clutch 2.
and are connected by a connecting ring 3. In this case, the bearing 1 includes an outer ring 12 and an inner ring 13 that sandwich the balls 11.
The one-way clutch 2 includes an outer ring 22 and an inner ring 23 that hold a roller 21 therebetween, and a spring 24 that presses the roller 21, and the connecting ring 3 is fitted into the seal groove 4 on the sides facing each other.

As shown in FIG. 3 as an example, the cross section of the connecting ring 3 has protrusions 31 formed on both end faces thereof.
By forcibly inserting this protrusion into the open end of the seal groove 4, it is possible to fit and firmly connect the two.

In this embodiment, the connecting ring 3 is fitted to the outer rings 12 and 22 of the bearing 1 and the one-way clutch 2, respectively, through the open ends of the seal grooves 4, but on the contrary, the open ends of the seal grooves on the inner ring side It is obvious that the connecting ring 3 may be configured to fit into the connecting ring 3 (not shown).

The material of the connecting ring 3 is generally made of resin or metal, but any other material may be used as long as it has appropriate elasticity to firmly connect the two. It can be anything.

Note that FIG. 4 shows another embodiment of the connecting ring 3, in which the outer periphery has a U-shaped cross section.

〔effect〕

As explained in detail above, this invention utilizes the seal grooves between the bearing and the clutch, and by pushing the resin or metal connecting ring into the seal grooves, the tightening force or frictional force strengthens both. can be connected to.

Therefore, compared to conventional products, because the clutch and bearing are one unit, it is possible to save on labor, time, and facility space when incorporating this into equipment, and because ordinary bearings are used as parts, costs can be kept low. Furthermore, even if the torque capacity or radial and thrust loads are changed, it is only necessary to change the clutch parts or bearing portion, thereby reducing development costs and time. Furthermore, if the seal groove in the clutch outer ring is used, the clutch direction can be easily changed, and many other advantages are obtained.
