Description

Technical Field

[0001] The present invention relates to the technical field of electric motors, and more particularly to an electric motor that is convenient for adding lubricant. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil, also known as the stator winding, to generate a rotating magnetic field and act on the rotor, such as a squirrel-cage closed aluminum frame, to form a magneto-electrical rotational torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the electric motors in the power system are AC motors, which can be synchronous motors or asynchronous motors: the speed of the motor's stator magnetic field and the speed of the rotor rotation do not maintain synchronous speed. The electric motor is mainly composed of a stator and a rotor. The direction of the force on the energized conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is the effect of the magnetic field on the force on the current, causing the motor to rotate.

[0003] Most electric motors currently on the market utilize a sealed design. While this offers certain advantages in terms of dust and water resistance, it also introduces numerous inconveniences during actual use, particularly with regard to lubrication and maintenance. Due to the sealed structure, it's difficult to regularly add or replace lubricants to moving parts such as bearings within the motor. This can lead to insufficient lubrication after prolonged operation, exacerbating wear and reducing service life. Furthermore, even where oil filling ports are provided, they are often obscured or restricted by the structure, making refilling difficult and impacting maintenance efficiency. Summary of the Invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide an electric motor that is convenient for adding lubricant and can achieve uniform oil filling of the electric motor.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] The cam is connected to the motor body by a toothed connection, and the toothed connection is connected to the gear train of the motor and the gear train, and the toothed connection is connected to the gear train of the motor.

[0007] A second spring is fixedly installed between the second wedge block and the fixed tube, and the second wedge block is slidably connected to the shell.

[0008] Coating plates are fixedly mounted on both ends of the transmission frame. The coating plates are arranged in an arc shape and are arranged corresponding to the driving shaft.

[0009] A sleeve is fixedly mounted on the inner wall of the shell, an end portion of the sleeve is slidably connected to a sliding rod, and the sliding rod is fixedly connected to the transmission frame.

[0010] The wedge block 1, the wedge block 2, the spring 2, the fixing piece, the transmission frame, the sleeve, the sliding rod and the coating plate are respectively provided in two groups and are symmetrically arranged.

[0011] The slot on the outer shell is provided with a cover. When oiling is required, the cover is manually removed, and then the plug on the injection dropper containing lubricating liquid inside is inserted into the slot. When the plug is inserted into the slot, it will resist the transmission tube that is slidably connected to the inside of the slot. The plug is pushed forward manually to lower the transmission tube. The transmission tube simultaneously carries the cross bar and the wedge blocks 1 at both ends of the cross bar down, and squeezes the spring 1. When the wedge block 1 descends, the wedge block 1 will contact the wedge surface of the wedge block 2 on the transmission frame and slide, causing the wedge block 2 to move inward. Both sets of wedge blocks 2 will carry the transmission frame inward through the fixing parts, and the coating plate fixedly installed on the transmission frame will approach the drive shaft.

[0012] An inner cavity is provided inside the coating plate, and a threaded hose is provided to connect two adjacent groups of the inner cavities.

[0013] A threaded hose 2 is provided between the fixed pipe and one group of the threaded hose 1, and the threaded hose 1 and the threaded hose 2 are both arranged in a threaded folded shape.

[0014] A plurality of spray holes are provided on the inner side of the coating plate, and the plurality of spray holes are communicated with the inner cavity.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This solution provides an auxiliary oil injection structure, which enables lubricating oil to be injected into the motor more conveniently and quickly, improving the oil injection efficiency while avoiding the problems of spillage or waste that may occur in traditional methods. The structure is reasonably designed, the oil injection process is simple to operate, and the lubrication operation can be completed without disassembling the equipment, reducing maintenance difficulty and labor costs. It not only ensures the full lubrication of the bearings and other components inside the motor, but also effectively extends the service life of the equipment. It is suitable for the daily maintenance and maintenance of various sealed motors. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] At present, most electric motors on the market adopt a closed structural design. Although it has certain advantages in dustproof and waterproof, it also brings many inconveniences during actual use, especially in terms of lubrication and maintenance. Due to the structural sealing, it is difficult to regularly add or replace lubricants to the moving parts such as the bearings inside the motor, which leads to insufficient lubrication after long-term operation, thereby increasing wear and reducing service life. In addition, even if some electric motors are equipped with oil filling ports, they are often difficult to fill due to hidden locations or structural limitations, affecting maintenance efficiency. Therefore, this solution sets up an auxiliary oil filling structure to enable lubricating oil to be injected into the motor more conveniently and quickly, thereby improving oil filling efficiency and avoiding the problems of spillage or waste that may occur in traditional methods. The structural design is reasonable, the oil filling process is simple to operate, and the lubrication operation can be completed without disassembling the equipment, reducing maintenance difficulty and labor costs. It not only ensures sufficient lubrication of the bearings and other components inside the motor, but also effectively extends the service life of the equipment. It is suitable for the daily maintenance and maintenance of various closed motors. Instructions for use: A cover is provided on the slot 6 on the housing 3. When oiling is required, the cover is manually removed, and then the plug 5 on the injection dropper 4 containing lubricating liquid is inserted into the slot 6. When the plug 5 is inserted into the slot 6, it will abut against the transmission tube 7 that is slidably connected to the inside of the slot 6. The plug 5 is manually pushed continuously to lower the transmission tube 7. The transmission tube 7 simultaneously carries the cross bar 21 and the wedges 8 at both ends of the cross bar 21 to descend, and squeezes the spring 9. The wedge 8 descends, and the wedge 8 contacts the wedge surface of the wedge 2 11 on the transmission frame 15 and slides, causing the wedge 2 11 to move inward. The two sets of wedges 2 11 will carry the transmission frame 15 to move inward through the fixing piece 16, and the coating plate 17 fixedly installed on the transmission frame 15 will approach the drive shaft 2. The oiling personnel then squeezes the injection dropper 4, and discharges the lubricating liquid inside the injection dropper 4 into the transmission tube 7 through the long plug 5, and finally enters the inner cavity 18 of each group through the fixed tube 10, the threaded hose 2 20 and the threaded hose 1 19, and then evenly sprays it onto the drive shaft 2 through the spray hole opened on the inner side of the coating plate 17, completing the oiling operation of the drive shaft 2; after the oiling is completed, the injection dropper 4 is pulled out, and under the action of the elastic deformation of the spring 1 9 and the spring 2 12, the various groups of structures inside the shell 3 are restored to their original state, and the cover plate is used to seal the slot 6.
