Bearing installation tool

This creation is about an installation tool, especially a bearing installation tool used to assist in the mounting of bearings.

The bearing is used to support the shaft and reduce the frictional resistance of the shaft, so that the shaft can be smoothly operated, which is a common necessary part of the transmission. However, if the bearing fails to provide an average pressure, it may cause problems such as bearing wear, skew, poor adhesion, etc., and easily affect the bearing life and the smooth operation of the shaft.

In this regard, a manufacturer has developed a bearing positioning tool set such as the Republic of China Invention Patent Publication No. I294813, comprising: a grip bar, at least one positioning block and a joint member, wherein the positioning block is coupled with the joint member. The grips are sleeved and fixed to each other, whereby the inner end edges of the bearings can be pressed against the inner end edges of the bearings to average the force applied during the tapping, so that the bearings can be positioned in the perforations of the axles.

However, when the positioning clamp of the above tool is disposed on the bearing, the skew of the positive shaft hole may not be surely caused, resulting in failure to provide the average pressure of the inner diameter edge of the bearing, which affects the stability of the bearing installation.

In order to further improve the stability of the bearing installation, the present inventors propose a bearing installation tool for mounting a bearing, the bearing comprising a shaft hole and a ring body located at a periphery of the shaft hole, the bearing installation tool comprising: The gripping rod includes an insertion end and a mounting portion adjacent to the insertion end; a positioning ring is mounted on the shaft hole, and includes a socket and a ring surface located at a periphery of the jack, the jack The insertion end is correspondingly inserted, the ring faces the shaft hole; and an impact member is detachably mounted on the mounting portion, and includes a pressing edge corresponding to the ring body of the bearing to be impacted by the impact The pressure of the piece moves over the ring.

Further, the mounting portion has a latching member for chucking the impact member.

Further, the latch member is a ball, and the impact member has a hole and a ring groove adjacent to the sleeve hole, so that the ball is correspondingly embedded when the sleeve of the impact member is sleeved on the mounting portion. The ring groove.

Further, the positioning ring has a blocking portion adjacent to the annular surface to abut the bearing side when the positioning ring is mounted on the shaft hole.

Further, a diameter of the insertion end is substantially the same as a diameter of one of the insertion holes.

Further, one of the apertures of the shaft hole has substantially the same diameter as one of the toroids.

Further, the diameter of one of the impact members is substantially the same as the diameter of one of the bearings.

The present invention is also a bearing installation tool for mounting a bearing, the bearing comprising a shaft hole and a ring body located at a periphery of the shaft hole, the bearing installation tool comprising: a grip bar comprising an insertion end and a mounting portion; The mounting portion is adjacent to the insertion end; a positioning ring includes a socket and a ring surface located at a periphery of the socket, and an aperture of the one of the holes is substantially the same as a diameter of the insertion end for the insertion The end corresponding to the insertion, the diameter of one of the annular faces is substantially the same as the diameter of one of the shaft holes, so as to be correspondingly mounted on the shaft hole; and an impact member is detachably mounted on the mounting portion, including a pressing edge The diameter of one of the pressing edges is substantially the same as the width of the ring of the bearing to provide a pressure of the ring body by the pressing edge of the impact member.

According to the above technical features, the following effects can be achieved:

1. The insertion end of the grip can be assisted by the positioning ring without shaking to improve the stability of the bearing installation.

2. Since the force can be applied to the grip bar, the installation efficiency can be improved without damaging the impact member, and the product durability is better.

3. The impact member is detachably coupled to the grip to replace the impact members of different specifications.

4. It is convenient to disassemble and assemble by using the ring groove of the ball and the impact member.

The detachment of the mounting portion (12) during the installation process is not limited thereto, and may be a combination means of reversible detachment such as magnetism. The impact member (3) comprises a pressing edge (33), wherein a diameter (L5) of the pressing edge (33) is substantially the same as a diameter (L6) of the ring body (A2) of the bearing (A) .

In the case of use, please refer to the third figure and the fourth figure. First, the bearing (A) is placed on the shaft seat (B) and corresponds to the bearing groove (B1), and the bearing (A) specification is corresponding. The impact member (3) is detachably mounted to the mounting portion (12) of the grip (1). In addition, the positioning ring (2) corresponding to the shaft hole (A1) specification of the bearing (A) is fitted into the shaft hole (A1). Then inserting the insertion end (11) of the grip (1) into the insertion hole (21) of the positioning ring (2) to assist the positioning of the grip (1) without shaking, and the impact member (3) can be The pressing edge (33) corresponds to the ring body (A2) of the bearing (A). Continue to refer to the fourth and fifth figures, and then the user can tap the grip (1) by a tapping tool (such as a hammer) to make the pressing edge (33) of the impact member (3) smoothly. Move the ring body (A2) of the bearing (A) to the appropriate mounting position of the shaft seat (B). Continued, please refer to the sixth figure. The positioning ring (2') and the impact piece (3') can be supplied in different sizes, so that the user can replace the bearing (A') according to different sizes to enhance the product. applicability. Continued Referring to the seventh figure, it is shown that the bearing installation tool of the present invention can provide a plurality of positioning rings (2) and impact members (3) of different specifications, and can be collected together with the aforementioned grip (1) in a tool box ( D) for easy collection, carrying or display.
