Abstract

PROBLEM TO BE SOLVED: To facilitate attaching/detaching work by providing each divided ring with a plurality of fitting holes along the circumference, and providing at least one of the fitting holes at the joint part of the divided ring. SOLUTION: A stop ring 10 is composed of two divided rings 11 formed by bisecting a ring member formed of a plate, and each divided ring 11 is provided with a plurality of fitting holes 12, 13 along the circumference. At least one of the fitting holes 12, 13 is provided at each joint part of the divided ring 11, and one to three other fitting holes are provided at intermediate parts so as to be four to eight fitting holes in all. Ring inner edge parts 11a are provided in such a way as to be fitted into a groove of a fixed member. With this constitution, the stop ring 10 can be easily mounted without enlarging or contracting a diameter at the time of fitting, and since the joint parts of the divided rings 11 are fixed by set screws, joint end parts are prevented from being twisted or deformed after fitting, and detachment is also facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a stop ring.

[0002]

2. Description of the Related Art A stop ring is widely used because it is fitted in an annular groove formed in a shaft or a hole to prevent movement of the shaft or a component inserted in the shaft.

A conventional stop ring is fitted in an expanded state when mounted on a shaft, and is fitted in a reduced diameter state when mounted on a hole, so that the mounting operation is not easy.
Once installed, removal was not easy. For this reason, the handling of the conventional stop ring was not always good.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stop ring which can be easily attached or detached.

[0005]

According to a first aspect of the present invention, a ring-shaped member made of a plate member is divided into a plurality of divided rings, and each divided ring is provided with a plurality of mounting holes along a circumference. Wherein at least one of the mounting holes is provided at a junction of the split rings.

The mounting hole can be formed by selecting either the outer peripheral edge or the inner peripheral edge from the center line of the ring depending on whether the mounting position of the stop ring is the inner edge portion or the outer edge portion. And

[0007]

FIG. 1 shows an example in which a stop ring is used to attach a bearing.
Reference numeral 1 denotes a machine or other frame to which a pulley 2 is rotatably mounted as an example. The pulley 2 is provided integrally with the rotating shaft 3, and
Is rotatably mounted via a bearing 4.

FIG. 2 is an enlarged view of a portion A in FIG. 1, and FIG. 3 is a perspective view of a stop ring of the present invention. The stop ring 10 is composed of two divided rings 11 obtained by dividing a ring-shaped member made of a plate material into two. Each divided ring 11 is provided with a plurality of mounting holes 12 and 13 along the circumference.

In this embodiment, the mounting holes 12 and 13 are
At least one of the joints (the holes 1
In addition to 2), 1 to 3 (holes 13) are provided in the intermediate portion, and the total is 4 to 8 holes. In the embodiment, since the inner edge 11a of the ring is fitted into the groove of the fixing member, the mounting holes 12, 13 are formed near the outer edge of the ring. In the case of fitting into the ring, the mounting holes 12 and 13 are formed near the inner peripheral edge of the ring.

Referring to FIG. 2, the outer race 5 of the bearing 4 is provided with an annular groove 50, and the frame 1 and the pulley 2
The stop ring 10 fitted in the annular groove 50 of the outer race 5 is fixed to the frame 1 by a set screw 14.

As described above, the stop ring 10 is attached by fitting the split ring 11 divided into two into the annular groove 50. Therefore, the diameter of the stop ring 10 is increased or reduced at the time of attachment like a conventional stop ring. The joint can be easily mounted without being attached, and the joint of the split ring 11 is fixed with the set screw 14, so that the joint end can be prevented from being twisted and deformed after the attachment.

In the embodiment, a round screw or a pan screw is used as the set screw 14. However, if a flat screw or a round flat screw is used, the ring surface will not be flat. it is obvious.

[0013]

The stop ring of the present invention is constituted by a split ring obtained by dividing a ring-shaped member into two parts, so that it is not necessary to increase or decrease the diameter when attaching to a shaft or a hole. There is an effect that the attaching or detaching operation is easy.
