Abstract

PURPOSE:To smoothly rotate a main cover by laying a guide piece on the top of the main cover and fixing guide rollers to sandwich the guide piece to a gear case. CONSTITUTION:Since a guide piece 17 laid in the longitudinal direction of both side parts of a main cover 2 is constructed in such away that the guide piece can be sandwiched by guide rollers 16 from the top and the bottom, sufficient clearance is not required between the guide rollers 16 and the guide piece 17 and the main cover can be smoothly rotated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the main force tX? The present invention relates to a rotating device for a rotary machine, and in particular, it relates to a rotating device for a rotary whose main force I <-, which allows the main shaft to rotate smoothly around a rotary shaft.

[Prior Art] The main force <- rotation device in a conventional rotary of this type will be explained with reference to FIG. 5 attached hereto. In the same figure, (+
) is a rotary, and (2) is a main cover. At the top center of this main cover (2) is a gear case (3).
is disposed, and in order to enable the main cover (2) to rotate back and forth around the rotation axis of the rotary (+), it extends to the front and back of the central part of the main cover (2). A sliding hole (4) is bored near the side wall of the gear case (3), and the side wall of the sliding hole (4) is formed to be able to freely slide back and forth while abutting the side surface of the gear case (3). . Frames (5) are mounted on both left and right sides of the gear case (3).
(5) is provided protrudingly, and brackets (6) (6) are fixed to the ends thereof in the front and back direction. Furthermore, this bracket (6)
(6) has rollers (7) (7), (7) on the front and back of its outer surface.
) (7) are provided with rotating shafts (8) (8), (8) (8), and the rollers (η (No, (η(7)) is loosely fitted into the rotary die hole.

On the other hand, guide pieces (9) (9) are installed in the longitudinal direction of both the left and right measuring portions of the main cover (2). Moreover, both ends of this guide piece (9) (9) are hitch (In) (10
), Qo) (to), and is formed in an elliptical arc shape centered on the rotation axis of the rotary 0). Further, a guide hole 0000 is formed in the center of the guide piece (9) along its longitudinal direction, and the rollers (7) (7), (7) are formed in the guide hole 01)(lD). )(7
) are loosely fitted, respectively, and these rollers (7) (7), (
Washers 0 (02) and (1) are fixed to the outer surface of (7) (7) to prevent the rollers (7) (7) and (7) (7) from coming off.

[Problems to be Solved by the Invention] In the conventional type, the roller (7) ( 7), (7) (7) are fitted loosely, and the outer surfaces of the rollers (7) (7), (7) (7) are held between washers Q7JQ7J, (I), so A roller (7) (
7), (7) (7) roll to rotate the main force (2) back and forth around the rotation axis of the rotor (1), it is inevitable that the rollers (7) ( 7), (7
)(7) and the guide hole 0f)01) requires a considerable clearance. If this clearance is not maintained sufficiently, smooth rolling of the rollers (7), (η(η) cannot be expected. Therefore, as mentioned above, it is common to have sufficient clearance. However, this clearance also causes play in the rolling part, which impedes rotary workability.Therefore, it is necessary to create a clearance that does not cause play in the rolling part and allows the main cover to run smoothly. A technical problem that must be solved arises in order to achieve rotation, and the purpose of the present invention is to solve this problem.

[Means for Solving the Problems] The present invention has been proposed to achieve the above-mentioned object. Guide pieces are installed on the upper surface of both sides of the main cover of the rotary in the front-rear direction, and the guide pieces are installed on the upper and lower sides of the main cover of the rotary. A rotary main body characterized in that a guide roller that can be held tightly and rolls is provided, and a bracket for supporting the guide roller is fixed to the end of a frame protruding from both sides of a gear case. It is an object of the present invention to provide a rotation device for the cover.

[Function] This invention is configured so that the guide rollers can sandwich and roll the guide piece installed across both the measuring sections of the main cover in the front and back directions from the upper and lower surfaces, so that the relationship between the guide roller and the guide piece is There is sufficient space between them, and smooth rolling is possible without the need for rearance. Therefore, since the guide piece is held between the guide rollers not only on the upper and lower surfaces of the guide piece but also on its left and right sides, the rolling part of the guide roller due to vibrations generated during rotary work is not affected. Extremely smooth rolling motion can be expected without any play, and therefore the main cover can be rotated back and forth smoothly.
This improves rotary workability.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, conventionally known techniques will also be explained.

Components that are the same as those in the conventional example shown in FIG. 5 are designated by the same reference numerals.

In FIG. 1, (1) is the rotary, and (2) is the main cover. A gear case (3) is disposed at the center of the upper surface of the main cover (2). A rectangular sliding hole (4) is opened from the front central part of the main cover (2) toward the rear, and the gear case (
The main cover (2) is formed to be rotatable back and forth while the side wall of the main cover (3) slides against the hole wall of the sliding hole (4). Further, a rear cover (2) is provided at the rear end of the main cover (2), and the rear cover (2) acts as a leveling plate and also acts as a plowing depth sensor during plowing depth control.

Furthermore, frames (5) (
