What should I do when the micro gear reducer motor generates heat and vibration?

I believe that many people are not unfamiliar with micro gear reducer motors. In many equipment, they need to be used to increase torque and reduce speed, but what should we do when there are faults such as heat and vibration?

The first is the heat problem. If the product is hot, you need to connect the cause of the heat first, which can be mainly divided into two cases.

One is that the product has serious heat but no abnormal noise. It is generally caused by too much lubricating oil. If there is a sound of metal parts rubbing inside the product while heating, it is mainly caused by the lack of lubricating oil. Noise, and the noise is getting heavier and heavier, and the corresponding load current is also increasing, which means that the product is in an overload state. At this time, it needs to stop running immediately.

The other is the tooth surface problem. The tooth surface problem is a common fault of the product, mainly because

The tooth surface clearance is worn, the tooth surface is pitted, or the new and old gears are not well meshed. Gear clearance wear is mainly manifested in that the product will have a knocking sound when the car is empty, but when it is under load, the sound will become smaller, and there is even no knocking noise. At this time, it is necessary to turn off the worn size. If there is no new gear for a while, the worn gear can be turned over and used. When the gear is just replaced, it is often accompanied by loud and uneven sound, especially when the old and new gears are used at the same time, because the tooth surfaces of the new and old gears have not been fully contacted, and they will run after a period of use. The sound will return to normal. If debris enters the gear, it will also cause uneven noise during operation. If such a situation occurs, it should be solved in time to avoid the product being scrapped after long-term use.

If there is pitting corrosion on the tooth surface, there will also be a "boom boom" sound during operation. At this time, it is necessary to stop the operation of the product immediately, and timely check whether the product is overloaded, the oil surface is too high, and the tooth surface is severely worn. problem, and according to the problem, the solution is given.

There are many users who are concerned about the problem of vibration. The common reasons for vibration during the use of the product are that the bolts are loose or broken, and the rolling bearing has been severely worn.

For the vibration caused by the bolt problem, it is necessary to check the connection part of each bolt to determine the bolted connection. If the bolt is rusted or broken, it needs to be replaced with a new bolt.

For vibration problems caused by bearing wear and excessive clearance, it is necessary to open the hole cover, inspect each bearing, and repair or replace the bearing according to the condition of the inspection.

In addition, the rotation of the prime mover shaft but the main shaft does not rotate will also cause the micro gear motor to vibrate. This is mainly because the gears lose their meshing ability due to cracked gears or damage to the roller keys. Repair or replace.
