Problems solved by technology

Therefore, there are problems in that it is very difficult to process the cylindrical body, a separate bracket must be prepared according to each radial bearing to be mounted, and the number of parts and the generation of errors are increased
[0008] But, above all, the conventionally known radial bearing screw conveying equipment has a big problem: it is impossible to recognize the state of contact between the radial bearing and the screw shaft with the naked eye
Therefore, it is equally difficult to adjust for maintaining proper preload between all radial bearings and the screw shaft

Abstract

The present invention relates to a contact-exposing-type screw conveying apparatus using a radial bearing. The screw-conveying apparatus using a bearing comprises: a screw shaft; a nut coupled to the screw shaft via a screw, wherein said nut comprises a plurality of rod-shaped bearing holders, each of which has a rod shape extending in the direction of the screw shaft, and which are spaced apart from each other in a circumferential direction along the outer surface of the screw shaft; a plurality of radial bearings arranged in the lower portion of each of the rod-shaped bearing holders along a helical path formed in accordance with the pitches of male screws of the screw shaft; and spacers for fixing both ends of each of the rod-shaped bearing holders, such that each of the rod-shaped bearing holders can maintain a predetermined distance from the center of the screw shaft and maintain a predetermined distance from each other in the circumferential direction of the screw shaft.

Description

technical field [0001] The present invention relates to a screw conveying device using a radial bearing, and more particularly, to a contact-visible bearing screw conveying device using a radial bearing in such a manner that the radial bearing is formed as an internal thread. Turn at regular locations in the inner surface of the nut attached to the screw shaft. Background technique [0002] A variety of screw conveyors are disclosed, each of which is used to threadably couple a screw shaft to a nut and then connect a power unit to either of the screw shaft and the nut, thereby allowing Either the nut (and the load connected to the nut) or the screw shaft (and the load connected to the screw shaft) move linearly. [0003] In this case, the nut has internal threads formed therein corresponding to external threads formed at the screw shaft, and the internal threads have various structures and shapes. Internal threads are formed by cutting threads into the inner surface of the...
