Precautions for gear reducers

2021-04-12 14:49:15   |  Precautions for gear reducers

The gear reducer is an independent closed transmission device between the prime mover and the working machine. It is used to reduce the speed and increase the torque to meet the needs of work. In some cases, it is also used to increase the speed and is called a speed increaser.

Precautions for gear reducers

Precautions:

Reason for leakage:

1. The pressure in the fuel tank rises

In a closed reducer, each pair of gears meshing and friction will generate heat. According to Boyle Mario’s law, as the operating time increases, the temperature in the reducer will gradually increase, and the volume inside the reducer No change, so the pressure in the box will increase, and the lubricating oil in the box will be splashed on the inner wall of the reduction box. Due to the relatively strong oil permeability, under the pressure in the tank, where the seal is not tight, the oil will leak out from where.

2. Unreasonable structure design of reducer causes oil leakage

If the reducer is designed without a vent hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box and oil leakage.

3. Too much fuel

During the operation of the reducer, the oil pool is greatly agitated, and the lubricating oil splashes everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil will accumulate on the shaft seal, joint surface, etc., resulting in leakage.

4. Improper maintenance process

During equipment maintenance, due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of the seal, and failure to replace the seal in time, oil leakage may also occur.

What is the normal temperature of the gear reducer
READ MORE

What is the normal temperature of the gear reducer?The working temperature of the gear reducer is generally within 80 degrees Celsius. Gear reducers are used in all areas of our lives. They are generally used for low-speed and high-torque transmission equipment. With the continuous development and growth of the reducer industry, more and more industries use the reducer, so the reducer is normal Will it be affected by temperature while working? Let me explain it to you.

Performance characteristics and classification of gear reducers
READ MORE

1. Performance characteristics:The gear reducer is an independent closed transmission device between the prime mover and the working machine, used to reduce the speed and increase the torque to meet the needs of work.Gear reducer is a combination of reduction motor and large reducer. No couplings and adapters are required, and the structure is compact. The load is distributed on the planetary gears, so the carrying capacity is higher than that of the general helical gear reducer. Meet the needs of high torque output in a small space.
