Abstract

PURPOSE:To aim at improvement in the setting efficiency of rolling elements, by holding the requisite number of rolling elements is a support in advance and after these rolling elements are assembled together with the support, melting this support. CONSTITUTION:A support 1 consisting of thin water soluble polyvinyl material is formed so as to hole the requisite number of rolling elements 2 to be set as coded into an insetting form. These rolling elements 2 are holded in this support 1 in advance, and these rolling elements 2 are inset in an insetting part 4 of a bearing body 3 together with the support 1 like ordinary assembling. Afterward, when this assembled bearing body 3 is dipped in a water tank, this water soluble support 1 is melted away into the water, thus the desired bearing is securable.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for assembling rolling elements in rolling bearings or swivel casters.

(Prior Art) Generally, rolling bearings or swivel casters require the incorporation of a large number of rolling elements such as balls, rollers, needles, etc.

Conventionally, rolling elements in rolling bearings or swing casters have been assembled by assembling the necessary number of rolling elements one by one.

In other words, when assembling, the required number of rolling elements such as balls, rollers, needles, etc. are taken out one by one and assembled into a race, etc., although there are differences in whether they are stored separately or in a row. .

Some rolling bearings use cages, but rolling elements are assembled one by one into the cage.

(Problems to be Solved by the Invention) A single rolling bearing or swing caster requires a large number of rolling elements, but if the rolling elements are installed one at a time, work efficiency is poor.

In addition, when assembling thrust ball bearings, swivel casters, or rolling bearings that can be disassembled and assembled freely, it is easy to assemble just one rolling element, but it is extremely difficult to assemble all the required number of rolling elements. However, it is necessary to apply grease to the races and the like in advance to hold them until all the rolling elements are assembled, resulting in problems such as poor work efficiency.

(Means for Solving the Problems) In order to solve these problems, according to the present invention, a rolling element that is a ball, roller, or needle in a rolling bearing or a rolling element for swinging in a swing caster is provided. The assembly method includes forming a holder to match the shape, holding a required number of rolling elements in advance on the holder, and assembling the rolling elements together with the holder; A method for assembling a rolling element in a rolling bearing or a swivel caster is provided, characterized in that the holder is then melted.

In the above configuration, the holding body is made of a water-soluble material,
After assembly, it can be removed by dissolving it with water or hot water.

Further, in the above configuration, the holder is made of a lubricant, and after assembly, it can be melted by heating or the like and used to lubricate the assembled rolling elements.

Further, in the above configuration, the holding body is made of a material that is soluble in chemicals outside the waterside, and after assembly, it can be dissolved by the chemicals and removed.

Furthermore, in the above structure, the holding body can be formed into a net shape having a large number of holes.

(effect) The above technical means works as follows.

The rolling elements, which are originally separate, are formed into a continuous shape that matches the shape of the assembly by being placed in the holding body in advance.

As a result, first, the assembly works so that the quantity control, handling, storage, etc. of the rolling elements are facilitated in the previous state.

That is, the assembly can be prepared in advance in the units of quantity required for assembly, and the quantity control can be performed by the number of holding bodies containing rolling elements, or by the number of holding bodies containing rolling elements, or by the number of holding bodies containing rolling elements, etc. Many types of rolling elements can also be managed for each holder.

Next, in some cases, the required number of rolling elements can be assembled at once, and complex assembly is also possible, such as when mounting upwards or on an inclined surface, or when rolling elements are assembled in multiple stages. Since the rolling elements can be handled in units of the required number, each individual rolling element functions so that it can be easily assembled without falling off.

After assembly, the holder becomes unnecessary; for example, if the holder is made of water-soluble material, it can be immersed in a water tank, etc. to dissolve the holder and remove it together with the water. The rolling elements function as if they perform their functions without any problems.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. FIGS. 1 and 2 show one embodiment.

(1) is a holder made of thin water-soluble polyvinyl, and the holder (11) is shaped so that it can hold the required number of rolling elements (2) to be incorporated in a manner that conforms to the shape of the assembly. There is.

A rolling element (2) is attached to this holder (1) in advance as shown in Figure 1.
, and assemble the rolling element (2) together with the holder (1) into the assembly portion (4) of the bearing body (3) as shown in FIG. 2 in the same manner as in normal assembly.

Then, if the assembled bearing body (3) is immersed in a water tank (not shown), the water-soluble holder (1)
is dissolved in water and removed, yielding a bearing similar to a conventionally known bearing.

FIGS. 3 and 4 show other embodiments of the present invention.

(5) is a holding body made of grease, which is a lubricant;
The holder (5) holds the necessary number of rolling elements (6) for assembly.
The grease is solid at low temperatures so as to enclose it, and is formed to match the shape of the installation part.

This holder (5) is assembled into the swivel part (8) of the swivel caster body (7) as shown in Fig. 4 in the same manner as in normal assembly, and then the caster body (7) is left at room temperature or If the solid holder (5) is melted by heating at a temperature slightly higher than room temperature, the holder (5) becomes a lubricant (5a), and the same rolling element (6
) is obtained.

It should be noted that the present invention is not limited to the above-mentioned embodiments. For example, it is possible to use a holding body that combines a lubricant and a water-soluble material, and remove only the water-soluble portion with cold water after assembly. Often optional.

(Effects of the Invention) As explained above, the present invention allows separate rolling elements to be managed or handled in units of the number required for assembly, making it easy to manage the quantity, manage inventory, or transport the rolling elements. Of course, complicated assembly has the advantage that rolling elements can be assembled easily and reliably during work.
