Description

Technical Field

[0001] The utility model relates to a self-lubricating and vibration-proof reduction gear motor, and particularly belongs to the technical field of reduction gear motors. Background Art

[0002] A reduction gear motor, also known as a gear reduction motor or reduction motor, is a motor-driven closed-type transmission gear reduction device. It integrates a motor and gearbox to reduce speed and increase torque to meet the operational needs of mechanical equipment. Gear motors offer a combination of small size, high torque, and low noise, making them the lifeblood of automation and a top choice for transmission machinery companies. Long-term operation without lubricant will produce loud noises during dry gear rotation, shortening the lifespan of unlubricated gears. Therefore, self-lubricating reduction gear motors are essential.

[0003] Most of the existing self-lubricating reduction gear motors only drip lubricant between the gears. The lubricant may be thrown out during the rotation of the gears. The thrown lubricant will accumulate inside the equipment and cannot be reused. Therefore, it does not meet the existing needs. In this regard, we propose a self-lubricating and vibration-proof reduction gear motor. Utility Model Content

[0004] The purpose of the utility model is to provide a self-lubricating and vibration-proof reduction gear motor to ensure that the lubricating fluid can be reused by itself, avoid the lubricant from accumulating inside the equipment, and help to increase the service life of the reduction gear motor.

[0007] Furthermore, the gear motor is sealed and protected by the protective shell and the rear cover plate, and the reduction gear assembly of the gear motor is lubricated by the self-lubricating component, so as to avoid friction overheating of the reduction gear assembly, which is beneficial to improving the service life of the gear motor.

One end of the first rotating wheel is inserted into a rotating groove provided on the inner wall of the protective shell, and one side of the first rotating wheel is in contact with a friction rod;

[0014] Furthermore, the first rotating wheel can be rotated by a belt transmission assembly.

[0015] The self-lubricating assembly also includes a counterweight, an oil storage block and a pressurized membrane;

[0016] One end of the friction rod is fixedly connected to a counterweight block, the outside of the counterweight block is connected to an oil storage block, the oil storage block is fixedly arranged on the inner bottom surface of the protective shell, a pressure membrane is fixedly installed on the inner side of the oil storage block, and the top surface of the pressure membrane is connected to the counterweight block;

[0017] Furthermore, the counterweight block can be arranged to press the pressure membrane under its own weight, so that the lubricating oil flowing into the oil storage block can be reused.

[0018] The self-lubricating assembly also includes a one-way oil inlet valve and an oil drain pipe;

[0019] A one-way oil inlet valve is fixedly installed on the oil storage block. One side of the oil storage block is connected to an oil drain pipe, and the other end of the oil drain pipe is located between the drive gear and the reduction gear.

[0020] Furthermore, the lubricating oil accumulated inside the equipment can flow into the oil storage block through the one-way oil inlet valve, and the lubricating oil can be repeatedly discharged between the driving gear and the reduction gear through the oil drain pipe.

[0023] Furthermore, the push rod can drive the second rotating wheel close to the friction rod, so that the second rotating wheel cooperates with the first rotating wheel to drive the counterweight to move vertically upward, which is conducive to the reuse of the lubricating oil.

[0024] The beneficial effects of the utility model are:

[0025] 1. The gear motor can be driven by a reduction gear by meshing the driving gear with the reduction gear.

The friction rod will drive the counterweight block to move vertically, so that the counterweight block can press the pressure membrane under its own weight, thereby allowing the lubricating oil flowing into the oil storage block to be reused.

The output shaft of the gear motor 2 can drive the driving gear 4 fixedly installed on the outside to rotate synchronously. A rear cover plate 3 is fixedly installed on one side of the protective shell 1 by bolts. The self-lubricating component provided on the inner side of the protective shell 1 is used to lubricate the reduction gear assembly of the gear motor 2;

[0035] The bottom of the protective shell 1 is made of rubber material, so that the whole device has a vibration-proof function. The top surface of the protective shell 1 is provided with an oil storage tank 7, through which the lubricating oil can flow directly to the driving gear 4, thereby lubricating the driving gear 4;

[0036] The upper end of the driving gear 4 is meshed with a reduction gear 5, which can drive the reduction gear 5 to rotate. A driving rod 6 is fixedly provided inside the reduction gear 5, and the driving rod 6 is inserted from the outside to the inside into the rotation groove opened on the inner wall of the protective shell 1, so that the driving rod 6 can rotate at a reduced speed;
