Gear reducer common fault solution

The gear reducer is very high in the transmission, and many of our common motor equipment can basically see the figure of the gear reducer.

For a device with such high usage rate, it will inevitably encounter various problems, such as excessive noise, damage to parts, etc. These faults require the technician to find a solution to repair the gear reducer equipment. Now, Xinghai summarizes the following common gear reducer solutions based on years of experience in gear reducer production and feedback from customers.

1.Gear wear
The gear wear problems of gear reducers are subdivided into the following aspects: tooth surface wear, gear shaft hole or keyway wear. Generally, for the case of less severe wear, plating can be used to restore the accuracy of the part.

2. Broken teeth
If the gears of the gear reducer are broken, then only new parts of the same model can be replaced.

3. Bearing hole screw hole thread wear failure
When the gear hole of the gear reducer of the gear reducer is damag…

How to solve the wear fault of gear reducer

Gear reducers are generally used in low-speed, high-torque transmission equipment, but in fact gear reducers are often used in high-speed mechanical environments, so it is inevitable to withstand multiple types of friction. If not protected, wear failures are likely to occur. Such problems often occur, so we should learn to deal with these wear and tear.

There are three kinds of wear faults of the gear reducer. One is the wear of the bearing chamber of the gear reducer, which includes the wear of the bearing housing, the bearing housing of the housing, and the bearing housing of the transmission. The second is the shaft diameter of the gear reducer gear shaft wear, the main wear parts are in the shaft head, keyway and so on. The third is the bearing wear of the gear reducer drive shaft.

For the wear failure of the gear reducer, the traditional solution is repairing after repair welding or brush plating, but both have certain drawbacks. Generally, the thermal stress generated by the hi…

Planetary gear reducer features

Planetary gear reducers are often used in transmission equipment with low speed and high torque. Generally, the power of high-speed operation such as electric motor is transmitted through the gears on the input shaft of the planetary gear reducer to mesh the large gears on the output shaft. Reach the purpose of deceleration.

The characteristics of the planetary gear reducer are mainly reflected in the following two points:
1. The planetary gear reducer will increase its output torque while reducing the speed. The torque output ratio is proportional to the motor output and the reduction ratio. Here, we need to pay attention to a detail. The torque output ratio should not exceed the rated torque of the planetary gear reducer.

2. The planetary gear reducer will reduce its load inertia while reducing the speed. The reduction of inertia is the square of the reduction ratio. In general, the motor will have an inertia value.
The planetary gear reducer is characterized by compact structure, s…

Common Use of Gear Reducer

The gear reducer functions as a matching precision and transmission torque between the prime mover and the working machine or the actuator. It is a relatively precise machine that is used to reduce the speed and increase the torque. Due to the great role of the gear reducer and its wide variety, it has a wide range of applications in our lives.

At present, food light industry, electric machinery, construction machinery, metallurgical machinery, cement machinery, environmental protection machinery, electronic appliances, road construction machinery, water conservancy machinery, chemical machinery, mining machinery, transportation machinery, building materials machinery, rubber machinery, petroleum machinery and other industries The field has strong demand for gear reducer products.

In terms of the range of people's frequent contact, in our lives, the common use of gear reducers is in various fields of industry and people's daily life, such as small machine tools, power tools, m…

Introduction to the reason why the reducer is broken

It is a common problem that the shaft of the reducer breaks the shaft. This problem is caused by the fact that the output shaft of the reducer is broken, except that the shaft of the reducer is broken due to the poor concentricity of the output of the reducer. Several reasons:

First, in the process of accelerating and decelerating, if the torque of the output shaft of the reducer is more than twice the torque of the extra output, and the acceleration and deceleration are too frequent, then the reducer will eventually Broken shaft. I think that this kind of appearance is less, so I will not introduce it further here.

Second, the selection of the fault caused the output of the gearbox to be insufficient. Some users mistakenly believe that only the additional output torque of the selected reducer can satisfy the operation demand. In fact, the first is that the additional output torque of the motor is multiplied by the reduction ratio, and the obtained value is in principle smaller than T…

Wear reduction notes for gear reducers

The gear reducer is the key equipment of the vertical mill system. Because the mission of the gear reducer is particularly harsh, it must be continuously subjected to shock, vibration and overload, and the service life requirement is more than 15 years. The reliability requirement is particularly high. Therefore, the use of the vertical mill puts higher demands on the design and manufacture of the gear reducer.

During the repair process, the parts of the gear reducer are always in the normal temperature state, no internal stress, no thermal deformation, crack, annealing, softening, no potential impact of cracks and cracks. The bonding strength is high, no falling off phenomenon, no hard point, high surface finish and adjustable hardness. Low carbon steel and low carbon alloy steel, medium carbon steel and medium carbon alloy steel, high carbon steel and high carbon alloy steel, high strength alloy steel, stainless steel, cast steel, cast iron, copper and copper alloy, aluminum and alu…
