Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a lubricating oil adding mechanism for a bearing part of a motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In the process of industrial production and processing, the motor is one of the indispensable power components. Therefore, the safe and correct use of the motor is also very important. When the motor is working, the internal bearing parts rotate for a long time, so they need to maintain a good lubrication state. Therefore, lubricating oil needs to be added regularly. Lubricating oil can ensure a good lubrication state.

[0003] The existing motor bearing lubricating oil adding mechanism is specifically a syringe-type lubricating oil adder. The nozzle length of the syringe-type lubricating oil adder cannot be adjusted during use. Therefore, it is convenient to add lubricating oil to the bearings outside the motor, but it is inconvenient to add lubricating oil to the internal bearings. In addition, the push-pull rod on the syringe-type lubricating oil adder lacks an effective limiting mechanism, and the push-pull rod is easily touched by mistake, causing the lubricating oil to be accidentally sprayed out.

Therefore, it is convenient to add lubricating oil to the bearings outside the motor, but it is inconvenient to add lubricating oil to the internal bearings, and the push-pull rod on the syringe-type lubricating oil adder lacks an effective limiting mechanism, and the push-pull rod is easily touched by mistake, resulting in the problem that the lubricating oil is accidentally sprayed out.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lubricating oil adding mechanism for the bearing part of the motor, comprising a lubricating oil storage cylinder, a cylinder cover is threadedly installed at the opening position of the upper surface of the lubricating oil storage cylinder, two operating handles are fixed to the outer surface of the cylinder cover, a push-pull rod is slidably installed on the cylinder cover, a push-pull handle is fixedly installed on the top of the push-pull rod, a piston disk is fixedly installed on the bottom end of the push-pull rod, the piston disk is sealingly fitted and slid on the inner wall of the lubricating oil storage cylinder, a slideway is opened on the cylinder cover and a locking plate is slidably installed in the slideway, an operating plate is fixedly installed on one end of the locking plate, and the push-pull rod The outer surface of the cylinder is provided with a plurality of locking grooves for the locking plate to be locked in, the upper surface of the locking plate is provided with a groove, and a locking plate is movably arranged in the groove, and the surface of the cylinder cover is provided with two locking holes used in conjunction with the locking plate, a connecting hose is installed through the bottom of the lubricating oil storage cylinder, one end of the connecting hose is connected and installed with an outer nozzle, an inner nozzle is slidably installed in the outer nozzle, a sliding plate is slidably installed on the outer surface of the outer nozzle, an adjusting rod is fixedly installed on the side of the sliding plate, the outer nozzle is provided with a through hole for the adjusting rod to pass through, and the outer surface of the inner nozzle is provided with a plurality of adjusting grooves used in conjunction with the adjusting rod.

By setting a locking plate for use in combination with a locking plate, when the locking plate is disengaged from the locking groove, the push-pull rod can slide up and down to add lubricating oil. After adding, the locking plate can be reset and snapped into the locking groove to lock the push-pull rod, thereby preventing the push-pull rod from being accidentally touched and causing the lubricating oil to be accidentally sprayed out.

The oil is added, and after adding, the locking plate 9 is pressed again so that the locking plate 9 enters the groove here. At this time, the elasticity of the spring 16 will drive the locking plate 7 to reset and snap into the locking groove on the surface of the push-pull rod 4, thereby locking the push-pull rod 4 to prevent accidental touch.
