Description

Technical Field

[0001] The utility model relates to the technical field of gearbox manufacturing, and specifically, the utility model relates to an oiling device for gearbox oil seals. Background Art

[0002] During the production process of the gearbox assembly, it is necessary to install oil seals. Since there will be a situation where the surface of the oil seal rubs against the workpiece housing during the equipment press-fitting of the oil seal, a large frictional force will cause the oil seal to be trimmed or cut, resulting in poor airtightness of the workpiece. It is necessary to disassemble and install the oil seal again, which is likely to waste a large amount of manpower and material resources for repairing the workpiece. It is necessary to perform an oiling operation before pressing the oil seal. Currently, manual oiling is mostly used in production, which is inconvenient to operate, has a long oiling time cycle, and affects production capacity.

It includes a glue bucket and also includes a dispensing tooling. An air pressure valve for connecting to a gas source to form air pressure in the bucket to extrude the lubricating grease is provided on the glue bucket. The dispensing tooling is provided with a grease inlet and a grease outlet. The grease inlet is connected to the glue bucket through a pipeline, and the position of the grease outlet on the dispensing tooling is correspondingly set opposite to the oiling position of the oil seal. The method for oiling the oil seal includes the following steps: connecting the glue bucket and the dispensing tooling through a rubber hose; sleeving the oil seal on the protruding cylinder of the dispensing tooling, and a group of grease outlets provided on the circumference of the cylinder correspond to the bending part of the oil seal; the gas source controls the pressurization of the glue bucket through the air pressure valve, and the grease in the glue bucket is pressed into the dispensing tooling through the air pressure, and then the oiling operation of the oil seal is completed through the grease outlet.
