PURPOSE: To easily fit an installing with one step without damaging a member to be installed. CONSTITUTION: A fitting member 2 covered with a shell-shaped thin guide member 7 made of the elastic material is fitted in a shaft 11 of a gear assembly 10, and the gear assembly 10 is inserted into an oil seal part 15 of an installing member 10 in the condition that the assembling auxiliary jig 1 is positioned at the head of the gear assembly 10 so as to easily install the gear assembly 10 without breaking the oil seal part 15, and this auxiliary jig 1 can be removed by drawing a handle 9 from the opposite side after installing the gear assembly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component assembling aid used for assembling components by inserting them into a bearing member.

[0002]

2. Description of the Related Art For example, in the case where a gear assembly is inserted and attached from the opening of an engine case of a motorcycle, the shaft end of the gear assembly may not be visible from the outside.
This causes a problem that the shaft end collides with the oil seal of the bearing and causes crimping and galling.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its object is to:
An object of the present invention is to provide a new auxiliary tool for assembling parts, which can smoothly assemble the parts without damaging the oil seal or the like.

[0004]

That is, according to the present invention, as an auxiliary tool for assembling parts for achieving the above object, a fitting portion for fitting with a shaft end of a mounting side member is provided at a rear end. At the tip of the mounting member, a shell-shaped guide member made of an elastic thin material that is guided by the bearing member on the mounted side at the time of assembly is mounted so as to cover the mounting member, and the tip of the guide member is mounted. Is clamped by the tip of the mounting member and the knob member.

[0005]

EXAMPLES Examples of the present invention will be described below. The drawing shows an embodiment of the present invention configured as an auxiliary tool used for assembling a gear assembly.

In the drawings, reference numeral 1 is a main assembly assisting tool,
The main body 1 includes a mounting member 2 for the gear assembly 10,
It is composed of a guide member 7 for assembling and a knob 9 for removing from the gear assembly 10.

The mounting member 2 is provided with a flange portion 3 having substantially the same diameter as the shaft 11 of the gear assembly 10 at the rear end thereof, and fitted at the outer end thereof into the inner hole 12 of the shaft 11. A cylindrical insertion portion 4 that frictionally engages with this portion is formed,
Further, this tip forms a shaft portion 5 that supports the guide member 7, and the end surface of the bulging head portion 6 forms a holding surface that fixes the guide member 7 in cooperation with the knob 9.

On the other hand, the guide member 7 is formed in a thin shell shape made of a flexible synthetic resin material such as polypropylene or a rubber material, and has a knob 9 on the bulging head 5 of the mounting member 2. It is configured to be integrally fixed, and the skirt portion 8 is configured to be circularly held by the flange portion 3 of the mounting member 2 and to be attached to the insertion portion 4 side while slightly protruding. Has been done.

In the embodiment constructed as described above, in order to assemble the gear assembly 10 to the oil seal portion 15 of the engine case, first, the gear assembly 1 is first assembled.
The insertion portion 4 of the auxiliary body 1 is fitted into the inner hole 12 provided at the end of the shaft 11 of 0.

As a result, as shown in FIG. 1, the auxiliary body 1 is fixed to the end of the shaft 11 of the gear assembly 10 with the outer peripheral surface of the shaft 11 covered with the skirt portion 8 of the guide member 7. Then, when the gear assembly 10 is inserted into the inside of the engine case with the auxiliary body 1 facing forward in this state, first, the shell-shaped guide member 7 made of an elastic material has an oil seal inside. It contacts the edge of 15 and is guided to its center.

Therefore, when the gear assembly 10 is further pushed in this state, the skirt portion 8 of the guide member 7 is pushed.
Since the shaft 11 covered by the oil smoothly fits into the oil seal 15 without damaging the oil seal 15, finally, by grasping and pulling the knob 9 projecting to the opposite end side of the oil seal 15, the assembly can be done. The auxiliary body 1 can be easily removed from the end of the shaft 11 of the gear assembly 10.

Although the present invention has been described above with reference to the example of the auxiliary assembly for mounting the gear assembly in the engine case, other shaft members and the like may be mounted on the bearing by hand. The auxiliary tool according to the present invention can be applied to the assembly of various devices.

[0013]

As described above, according to the present invention, a mounting member provided at the rear end with a fitting portion for fitting with the shaft end of the mounting side member covers the mounting member and is mounted. The elastic shell-shaped guide member guided by the bearing member on the side is attached, and the shaft member on the mounting side is mounted on the bearing member on the mounted side via this assembly aid, so that the mounting member can be mounted by blind touch. Even when fitted to the mounted member, the elastic guide member does not damage the mounted member, and the mounting member can be mounted on the mounted member very easily by being guided by the elastic guide member. Instead, by attaching a knob to the tip of these members, you can easily remove this assembly aid from the opposite side by attaching the knob to the mounted member and then attach this kind of member to each other. Efficient assembly It is possible.
