Abstract

PURPOSE:To dispense with caulking work and easily and securely attach a counterweight to a rotary member, by applying a brazing material to the peripheral surface of the counterweight, inserting the weight into the rotary member and then applying electricity to melt the brazing material. CONSTITUTION:To attach a counterweight 2 to a rotary member 1 to eliminate its imbalance, a brazing material 5 such as silver solder is first applied to at least part of the peripheral surface of the counterweight and the weight is then screwed into the tapped hole 1a of the rotary member. Electricity is thereafter applied to the counterweight 2 to melt the brazing material 5 between the weight and the rotary member 1 to conjoin them to each other. According to this method, conventional caulking work is dispensed with so that the dropping- off of the counterweight due to insufficient caulking and the damage to a threaded part due to excessive caulking are avoided. The attachment of the counterweight 2 to the rotary member 1 is thus made easy and secure.

Description

【発明の詳細な説明】 本発明は回転体のバランシングを行なうだめのバランス
ウェイトの取付方法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for attaching a balance weight for balancing a rotating body.

縁部に重鍾即ちバランスウェイトを装着する。In general, a rotating body needs to be balanced around the center of its axis when it rotates, but in the finished state of a rotating body, it is usually not perfectly balanced around the center of its axis. For this reason, a heavy peg, or balance weight, is attached to the outer edge of the rotating body for the purpose of correcting this unbalance.

具合が生ずることが多々あった。Figure 1 shows a conventional method of mounting such a balance weight.
Give an example. That is, conventionally, the balance weight 2 is connected to the rotating body 1.
It was screwed in, and the end was tightened with a shark stick 8 and a hammer 4 to prevent it from coming out. However, with such a mounting method using tightening, problems such as the balance weight 2 not being pulled out due to the uneven tightening, and damage to the threaded portion due to the tightening life often occur.

本発明は上記に鑑みなされたもので、極めて簡単な手段
で以ってバランスウェイトを確実に回転体に装着する方
法を提供することを目的とする。The present invention has been made in view of the above, and it is an object of the present invention to provide a method for reliably mounting a balance weight on a rotating body using extremely simple means.

以下第２図を参照して本発明の１実施例につき説明する

ってもよい。The balance weight 2 is attached to the rotating body 1 by the following method. A brazing material 5 such as silver solder or solder is applied to all or part of the outer periphery of the balance weight 2 formed by machining, and then the balance weight 2 is screwed into the screw hole 1a of the rotating body 1. Next, electricity is conducted to the balance weight 2 to melt the brazing material at the joint part 9 by Joule heat, thereby fixing the two together. In the above embodiment, the balance weight 2 is screwed into the rotating body 1, but the balance weight 2 may be press-fitted and brazed without providing a screw.

と共に。The present invention is constructed as described above.9 According to the method of the present invention, the conventional tightening work can be omitted, so that problems such as falling off of the balance weight due to insufficient tightening and damage to the threaded part due to over tightening can be avoided. In addition to being able to eliminate problems caused by strangulation.

従来方法に較べ作業工数が低減される。The number of work steps is reduced compared to the conventional method.
