Tianjin Lianxing Transmission: High quality cycloidal reducer, suspended gear reducer, dedicated reducer for mixing station, feeding belt reducer, mining reducer, enveloping worm gear reducer, hard tooth surface gear reducer, large non-standard reducer.
The possible faults that may occur during the use of the gearbox include oil leakage, overheating of the bearing area, loud noise, excessive temperature of the gearbox oil pool (above 70 degrees), abnormal noise of the gearbox, shifting of the driving shaft, bearing fragmentation, gear damage, etc. The causes and preventive measures are analyzed.
A reducer is a power transmission mechanism that uses a speed converter of gears to reduce the rotation of the motor to the desired number of revolutions and obtain a larger torque.
There are many types of reducers, which can be divided into gear reducers, worm reducers, planetary reducers, and their combined reducers according to the transmission type;
According to the number of transmission stages, it can be divided into single stage and multi-stage reducers; According to the shape of the gears, they can be divided into cylindrical gear reducers, conical gear reducers, and conical cylindrical gear reducers;
According to the layout of the transmission, it can be divided into deployable, split, and coaxial reducers.
Gears adopt two forms of lubrication: oil pool lubrication and circulating lubrication.
The lubricating oil should be regularly checked and replaced. When a newly installed reducer is first used, it must be replaced with new oil after 10-15 days of operation. In the future, the quality of the oil should be checked regularly (2-3 months), and if it does not meet the requirements, it should be replaced immediately. Generally, the oil should be changed at least every six months.
What are the reasons for the pitting and peeling of the gearbox gear?
1. Material, hardness, and defects.
The material of the gear does not meet the requirements; The main factor affecting the contact fatigue strength of gears is the low hardness after heat treatment, which cannot guarantee the expected contact fatigue strength of gears. In addition, defects on the surface or inside of the teeth are also one of the reasons for insufficient contact fatigue strength.
2. Poor gear accuracy.
The gear processing and assembly accuracy do not meet the requirements, such as poor meshing accuracy and motion accuracy. There is also a large error in the center distance of the shell of the circular arc gear.
3. The lubricating oil does not meet the requirements.
The grade of the lubricating oil used is incorrect, and the viscosity of the oil is low, resulting in poor lubrication performance.
4. The oil level is too high.
If the oil level is too high, the temperature of the oil increases, which reduces the viscosity of the lubricating oil, damages the lubrication performance, and reduces the working thickness of the oil film.
Could you please briefly analyze the reason for the gearbox shaft coupling?
1. It is due to a broken tooth that causes the input shaft to lose axial restraint and cause shaft string.
2. It is caused by the loose fastening between the driven gear on the intermediate shaft and the shaft. In actual transmission, often due to insufficient interference between the driven gear and the intermediate shaft, the driven gear produces axial displacement relative to the intermediate shaft, resulting in axial displacement of the input shaft. Therefore, insufficient interference is the main reason for the gearbox shaft string.
3. The steering of the gearbox also has a certain impact on the tandem shaft.
Could you please briefly analyze the reasons for the high temperature of the gearbox oil?
1. The lubricating oil is unqualified or has been used for too long.
2. Excessive lubricating oil is not conducive to the heat dissipation of the gearbox mechanism.
3. Damaged parts. Damaged parts
