The present invention relates to a grease injection device for injecting grease into a bearing widely used in industrial machinery, and more specifically, to automatically inject grease into a bearing using a pneumatic press that is advanced by pneumatic pressure. Rather, the present invention relates to an automatic grease injection device for bearings capable of injecting grease regardless of the size of the bearing.

In general, bearings such as ball bearings and roller bearings, which are used as main parts in industrial machines, are filled with a grease for lubricating grease, which is a gel-type oil, to allow the bearings to rotate smoothly.

The method of filling grease inside the bearing is, for example, by putting the bearing inside a grease container containing a large amount of grease, and then moving the grease on the surface of the bearing by an operator floating the grease by hand. Many methods of filling grease are used.

However, this method has a large amount of grease was wasted because a large amount of grease is buried in the hands or gloves of the worker as it is not used, and a large amount of grease is wasted so that there is an uneconomic problem.

In addition, there is a problem in that grease is applied to places such as a worker's hand or clothes, and the clothes or gloves are always changed and worn, and there is a problem in that the grease is not washed well by soap or the like.

In order to solve this problem, various devices for injecting grease into a bearing have been devised.

As an example, 'Bearing grease injection device', Utility Model Application No. 193-21360, has been conceived and disclosed, and according to the claims of the published publication, a handle bar installed below the lower end cap of the grease container, and the handle It consists of a grease compression device that compresses grease in the grease cylinder in conjunction with a stand, and a bearing landing device that lands a bearing on the upper end cap of the grease cylinder. The grease cylinder is formed of a cylindrical tube with a predetermined length, In the upper and lower threads, upper and lower stoppers are screw-assembled and shaft holes are formed in the center of the lower stopper, and the lower end of the rotating shaft penetrating the inner center of the grease barrel is freely installed on the upper side, and the lower side is the above. The handle bar is connected to the lower part of the rotating shaft and the high information wool. The upper end of the rotating shaft is equipped with a shaft pin. Rotated freely in the center of the bottom surface, the left side of the outer circumference is formed with a square piston is screw-assembled compression piston in the outside of the pressure ring pressed against the inner wall of the grease tube, the upper end cap is a disc-shaped stopper with a concave upper surface in the center The fixed shaft formed with the threaded part is installed vertically, and is circumferentially penetrated in the circumference of several ejection holes, and the bearing is inserted into the fixed shaft by screwing a bearing landing hole having a conical bottom surface onto the fixed shaft to press the bearing. It is configured to screw-assemble a lid that covers the outer side of the upper cap above.

Therefore, after the bearing is seated on the fixed shaft, the bearing seated using the bearing seating hole is fixed to the fixed shaft, and the grease filled in the inside of the grease cylinder is ejected through a plurality of ejection holes by turning the handle bar. By filling the inside of the bearing, it is easy to fill the inside of the bearing with grease.

In this case, however, in order to fill the grease inside the bearing, the grease compressor is raised by turning the handle bar with the other hand while holding the outside of the grease container with one hand so as to raise the grease compressor. By ejecting the grease, a lot of force is applied and the worker is easily tired.

Moreover, due to the nature of slippery grease, the outer circumferential surface of the grease can only be slippery, which causes a lot of difficulties in gripping the grease. The grease barrel is detached from the operator's hand, and the bearing seated has dirt or other injuries. I am always exposed to the problem.

As another example, 'Bearing grease automatic injection device', which is registered utility model No. 171389, was devised. As can be seen from the claims in the registered publication, the device for uniformly and automatically injecting and applying a certain amount of grease uniformly to the inner ball of a bearing comprises a rotary workbench, a support, and a storage container controlled by a control device. The rotary worktable is formed with a plurality of sheets having through holes corresponding to the number of balls of the bearing formed at corresponding positions, and is configured to be rotatable by an angle corresponding to an arrangement interval of the seats by the shaft, and the support is a rotary worktable. A cylinder having an injection disk installed at the front end of the injection disk at a position corresponding to the upper and lower seats is provided, and injection pins corresponding to the number of balls of bearings are installed at corresponding positions on the surface circumference of the injection disk, which faces the rotary worktable, Storage container is connected, and to supply grease to the injection disk by hose on the cylinder outlet side Consists of.

Therefore, grease is automatically injected into the inside of the bearing to solve some of the problems caused by the grease injection by the conventional manual method.

However, the conventional bearing grease injection device has a problem in that its components are complicated, leading to an increase in production cost. Also, when it is fixedly installed in one place, for example, to move the work space to another place. There is a problem in that the cost of re-installation as well as the delay of the work time, because the complex installation of the device must be removed after moving to remove.
