Description

Technical Field

[0001] The invention relates to the technical field of motor noise reduction, and in particular to a noise reduction motor for warp knitted fabric production equipment. Background Art

[0002] Warp knitted fabric is also called warp knitted fabric. Warp knitting is a textile process in the field of knitting. It uses one or several groups of parallel yarns to Feed all the working needles of the machine and at the same time This method is called warp knitting, and the knitted fabric is called , the use of motors is indispensable in the processing of warp knitted fabrics;

[0003] The prior art patent CN110994905A discloses a noise reduction motor. When the airflow flows through an air flow channel with multiple air guide plates built in, a swirl flow is generated, which enhances the stability of air pressure fluctuations and effectively reduces the wind noise generated when the airflow flows through the air flow channel; in addition, the shock-absorbing rubber sleeve can reduce the vibration generated by the motor when it is working, further improving the noise reduction performance created by the present invention. The above scheme mainly improves the vibration and wind noise when in use, but when the motor is in use, in addition to the wind noise and vibration noise, it also generates electromagnetic noise and bearing noise. The electromagnetic noise can be adjusted and controlled by a frequency conversion controller. The bearing noise can only be replaced in time with the long-term use of the motor drive shaft. Lubrication can improve the noise and life of the motor bearing, but because the warp knitting machine is relatively large and the number of motors is large, manual oil drip lubrication is performed one by one, which is inefficient and has poor lubrication effect on the bearings inside the casing.

[0032] An external lubrication component is provided to lubricate the first bearing 4 and the second bearing 5, and the external lubrication component includes an adjusting mounting disk 12 and an oil box 13. The adjusting mounting disk 12 is threadedly plugged into one side of the bearing seat 2, and the oil box 13 is rotatably plugged into one side of the adjusting mounting disk 12. A pressure tube 14 and an oil drip tube 15 are horizontally arranged on the upper and lower sides of the oil box 13 close to the bearing seat 2, respectively. An annular thread groove 11 is provided on the side of the bearing seat 2 away from the warp knitting drive motor 1, and a thread ring is provided on one side of the adjusting mounting disk 12, and the thread ring is threadedly plugged into the annular thread groove 11. A rotation groove is provided at the center of one side of the adjusting mounting disk 12 close to the thread ring, and the oil box 13 is rotatably plugged into the rotation groove. The oil box 13 can be plugged into the rotation groove by bearing plugging, or it can be movably plugged by adding a limit ring to the edge, so that the oil box 13 can remain stationary when the adjusting mounting disk 12 rotates.

[0033] An annular oil chamber is provided in the oil box 13, and an air groove and an oil groove are provided at the upper and lower ends of the annular oil chamber respectively. A through-hole 10 is provided horizontally through the upper and lower ends of the fixed outer ring of the second bearing 5. The pressure tube 14 and the oil drip tube 15 respectively penetrate the two through-holes 10 through the sealing rubber sleeve and are inserted into the lubrication chamber. A spring groove 16 and a piston groove 17 are provided on both sides of the air groove of the pressure tube 14 in turn. The piston groove 17 is located between the spring groove 16 and the oil box 13. A spring groove 16 and a piston groove 17 are provided horizontally and movably inserted at the positions of the spring groove 16 and the piston groove 17 in the air groove. A reciprocating control rod 18 is provided with a pressure plate on one side of the reciprocating control rod 18 placed in the spring groove 16, a reciprocating spring 19 is sleeved on one side of the reciprocating control rod 18 close to the piston groove 17, and a piston 20 is provided on one side of the reciprocating control rod 18 placed in the piston groove 17. The lubricating oil in the annular oil chamber is collected at the bottom under the action of gravity, and the oil dripping pipe 15 is also designed at the bottom. When the air pressure above the annular oil chamber increases, the lubricating oil in the annular oil chamber will be pushed into the lubrication chamber surrounded by the first bearing 4, the second bearing 5 and the sealing ring 8 through the oil dripping pipe 15, so as to continuously lubricate the first bearing 4 and the second bearing 5.

[0034] Embodiment 2: On the basis of embodiment 1, a control component is set to control whether the oil drip tube 15 delivers oil for lubrication. The control component is arranged on the side where the motor output shaft 6 is placed in the bearing seat 2, and the control component includes a control plate 22. One side of the reciprocating control rod 18 passes through the air groove and is provided with a push block 21. The control plate 22 is arranged on the side of the lubrication groove cavity close to the first bearing 4.

The oil groove of the oil drip tube 15 is provided on one side close to the oil box 13. There is a one-way valve. When the connection state between the mounting plate 12 and the bearing seat 2 is adjusted to fit, the longer the length of the pressure pipe 14 and the oil dripping pipe 15 inserted into the lubrication cavity is, the higher the speed of the motor output shaft 6 can drive the control plate 22 to rotate synchronously. At this time, a number of push balls 23 can push the reciprocating control rod 18 to squeeze the reciprocating spring 19. Then, under the elastic action of the reciprocating spring 19, the piston 20 reciprocates, and the lubricating oil in the annular oil cavity of the oil box 13 pushes the one-way valve in the oil dripping pipe 15, and the lubricating oil drips from the oil dripping pipe 15 into the inner wall of the sealing ring 8 in the lubrication cavity;

[0035] On the contrary, when the distance between the adjustment mounting plate 12 and the bearing seat 2 is greater than the reciprocating distance of the reciprocating control rod 18, the push ball block 23 cannot contact the push block 21, and the lubricating oil in the annular oil chamber is stored and waits for use;

[0036] A plurality of diffusion brushes 24 are symmetrically provided on the outer peripheral side of the control disk 22, and one side of the diffusion brush 24 is in contact with the inner peripheral side of the sealing ring 8. When lubricating oil is adhered to the lower inner wall of the sealing ring 8, the high-speed rotation of the control disk 22 can bring up and splash the lubricating oil through the diffusion brush 24, so that the first bearing 4 and the second bearing 5 are evenly lubricated.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
