Description

Straight line moving device using bamboo material

The present invention relates to a linear transfer device using a bamboo material to improve the quality characteristics of the product with a simple structure using a bamboo material and to significantly reduce the manufacturing cost.

The linear movement device, which is composed of a linear motion guide or a linear bush or the like and a guide means such as a rail, has a structure that reduces frictional resistance during movement of the mover.

Such a linear movement device is used in various fields, such as a simple conveyance that does not require a great deal of precision from an automation device that requires high precision.

Conventional linear mobile devices have a structure in which a plurality of balls installed in the mover are circulated along a circular trajectory and in point contact with guide means such as rails, and thus have a low allowable load, and a high load capacity is used even when a large number of balls are used. There is a problem that is difficult to do and the wear progresses quickly and the life is short.

In addition, there is a disadvantage that the number of parts and the assembly cost is excessive and the manufacturing cost is expensive due to a complicated structure in which a plurality of balls are circulated.

In addition, since the flow is generated when a large number of balls are moved, impact and noise are severely generated, resulting in noise pollution, and a short period of lubricating oil injection.

In addition, cost is wasted by using expensive and high-precision products unnecessarily even in the field of simple conveyance, which does not require much precision.

In addition, since the structure is complicated, as well as failure occurs because it is made of a metal material, when not used for a long time or when exposed to moisture corrosion occurs short life, there is a disadvantage that it is difficult to use underwater in corrosion problems.

The present invention is to solve the above problems,
