Abstract

PURPOSE: A protecting method for a rotation machinery is provided to improve durability and life span of the rotating apparatus through eliminating abrasion and breakage of the apparatus caused by excessive rotating force through operating the rotating apparatus under a proper rotating force. CONSTITUTION: A drive coupling(7) is engaged with a passivity coupling(8). Circular seats(14) are arranged on an engaged surface of the couplings for locating a steel ball(9). To adjust attaching force of the couplings, a spring(3) is inserted to the drive coupling. To adjust compressing force of the spring, an adapter screw(5) is formed on an outer surface of an adapter(4). Moreover, a body screw(6) is formed on an inner surface of a body(1). Therefore, height of the body screw is adjusted. Herein, components are formed in the body for being protected from external circumference. A flange is formed at a lower end portion of the body for being conveniently combined with a rotation machinery. Moreover, a rotation shaft of the rotation machinery and the passivity coupling are conveniently connected through forming the passivity coupling in a cylinder shape.

Description

Safety Catch For Rotation Machinery}

The present invention relates to a device for protecting a device that transmits power by rotational movement, which can be used in all industries, and more particularly, by adding the present invention to a device operated by a force generated by an electric motor or a manpower. Invented for the purpose of prolonging the life by preventing wear and damage of the device, the device is driven by receiving external power (motor or manpower) directly. It was designed to separate the drive shaft so that it could be driven and then to block the excessive force before the device was worn or damaged when any external excessive force was transmitted to the device driven by normal force.

In particular, the manual operation of valves and floodgates related to water and sewage facilities does not have safety facilities as in the present invention, causing problems such as twisting of the rotating shaft, wear and damage of the equipment due to excessive force, and thus causing huge losses. It was brought.

In recent years, some safety devices have been attached to devices using electric motors, but there are few protection devices in the more widely installed manpower devices. Therefore, it is bad for the life of the device and other equipment to take measures to protect such devices. It is very important with regard to affecting.

The present invention has been made to solve such a problem, by separating the power transmission shaft of the device for transmitting power in the rotational movement, by using a spring (3) and presser (4) to adjust the force to connect the separated shaft Its purpose is to increase the durability and lifespan of the equipment by eliminating elements such as wear and damage of the equipment caused by excessive rotational force by enabling it to operate only under the proper rotational force of the device.

The configuration of the present invention described above is divided into a drive shaft connecting plate (7) and a drive shaft connecting plate (8) to which the power is transmitted by engaging the drive shaft connecting plate (7) and the transmission shaft of the drive shaft connecting plate (7) directly to receive power; On the surface of the driven shaft connecting plate 8 which is engaged therewith, the connecting plate seats 13 and 14 on which the metal sphere 9 is to be placed are symmetrically formed, and the driving shaft connecting plate 7 and the driven shaft connecting plate 8 are formed symmetrically. It consists of a spring (3) and the presser (4) for adjusting the engaging force of the), characterized in that the power can be transmitted only by the proper rotational force required for the device to rotate.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, FIGS. 1, 1-1, 2, 2-1, 3, 4, and 5.

1 is a cross-sectional view schematically showing the configuration of a rotating machine protection device according to the present invention, Figure 1-1 is a cross-sectional view comparing the state in which the driven shaft connecting plate 8 is co-rotated due to excessive force. 2 is an assembled outline view of FIG. 1. 3, 4, and 5 are parts of the main parts shown in FIG.

In Fig. 1 there is a drive shaft connecting plate 7 which receives external power directly, and a driven shaft connecting plate 8 which meshes with the connecting plate 7, and the power transmission is reliably transmitted without slipping and each of them is rotated. In order to prevent the detachment of the metal spheres, the circular-shaped seats 14 and 15 of the ball shape are formed on the surface where the connecting plates 7 and 8 meet, so that the positions where the metal spheres 9 will be located are symmetrical.

In addition, a high-elastic spring (3) is inserted on the drive shaft connecting plate (7) to adjust the force for bringing the two connecting plates (7) (8) into close contact, and the presser (4) to adjust the compression force of the spring (3) The presser screw 5 is formed on the outer side of the body, and the body screw 6 is also formed on the inner side of the body, and the screw presser 5 and the body presser 6 engage with each other to raise the height of the presser presser 6. It is structured to control. This is to adjust the compression force of the spring (3) is to shape the upper portion of the body presser 6 in a square so that it is possible to easily adjust the body presser 6 only with a simple mechanism. All parts related to power transmission are structurally formed in the body (1) to protect from external environmental conditions, and the international standard (ISO) at the bottom of the body (1) to facilitate the connection to the rotary machine (15) ), The joining flange was shaped. In addition, in order to facilitate the connection between the shaft 16 of the rotary machine 15 and the driven shaft connecting plate 8, the driven shaft connecting plate 8 is shaped into a cylindrical shape, and the connecting bundle 11 is detached from the cylinder. Easily sandwiched, the connecting bundle lid 12 was formed in a prefabricated manner so that the connecting bundle 11 is not separated.

Briefly summarized above, the spring to adjust the close contact force of the driven shaft connecting plate 8, the two connecting plates (7) (8) to rotate in engagement with the drive shaft connecting plate (7) that receives external power directly (3) and presser (4), metal sphere (9) and connecting plate grooves (13) and (14) to maximize the engagement of the two connecting plates (7) (8) and the like are the main components of the present invention.

According to the present invention described above, by combining the components for separating and connecting the drive shaft connecting plate 7 and the driven shaft connecting plate 8 in a compact structure so as to protect the rotary machine from excessive transmission of power. Excessive loss of tangible and intangible due to wear and breakage of the rotary device 15 due to excessive transmission of power can be prevented and prevented in advance, thereby maximizing the life of the device as well as maximizing the management of the device.
