Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing grease filling equipment, and more specifically to a bearing grease filling machine. Background Art
[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings often need to be used in conjunction with lubricating grease. In the process of filling lubricating oil, an oil gun similar to a syringe is usually used to push the lubricating oil in with force to achieve injection. However, since there is often lubricating oil injected last time in the bearing, the lubricating oil becomes waste lubricating oil after long-term use. In the process of injecting lubricating oil again, it is necessary to overcome the resistance brought by the internal waste lubricating oil and squeeze out the waste lubricating oil injected last time before the injection can be completed. A lot of force is required during the injection process, and the labor intensity of the staff is relatively high.
[0003] The existing announcement number is CN219796849U, and its name is a bearing lubricating oil filling device, comprising a cylinder and a cylinder cover, one side of the cylinder cover is connected to an oil filling pipe, the other end of the oil filling pipe is connected to an oil outlet, and a bracket mechanism is also provided under the cylinder, a threaded sleeve is penetrated through the surface of the cylinder, a screw is threadedly connected to the surface of the threaded sleeve, and a push plate is slidably provided inside the cylinder, and the rotating rod is driven to rotate by turning the knob, so that the rotating rod rotates the screw through the second gear and the first gear, and the screw and the threaded sleeve convert the rotational motion into linear motion and convert the torque into thrust, thereby achieving a labor-saving effect, and the second gear drives the large first gear with a small gear, which can also achieve a labor-saving effect, thereby facilitating the staff to fill the oil and saving the staff labor.
[0004] However, when the above-mentioned bearing is filled with grease, the oil outlet and the oil filling port of the bearing are mostly squeezed by a needle-shaped mouth to fill the grease into the bearing. This results in a smaller contact area between the oil outlet and the oil filling port of the bearing. The existing bearing grease filling device lacks a pressing and fastening device. When filling, manual force is required to press the oil outlet and the oil filling port of the bearing to make close contact, so as to avoid the reaction force of the grease entering from pushing the oil outlet out, causing grease overflow, resulting in inconvenience in filling the bearing with grease.
