Harmonic reducer bearings are produced for matching harmonic reducers. They are compact in shape and have mounting holes for easy installation. They are suitable for various types of harmonic reducers. Oil leakage from the end cover of harmonic reducer bearings is also common. In response to this problem, relevant personnel have summarized the causes and treatment methods of oil leakage, let’s take a look~

Causes of oil leakage from the bearing end cover of the harmonic reducer

1. For the oil leakage of the non-shaft extension cover, the main reason is that the gap between the end cover and the box body is relatively large.

2. The main reasons for the oil leakage of the end cover of the shaft extension are that the gap between the end cover and the box is large, the input or output shaft and the inner hole of the end cover are missing or the seal is damaged, the vent plug is blocked, and the oil level is too high.

The treatment method of oil leakage of the bearing end cover of the harmonic reducer

1. For the non-shaft extension cover, it can be reprocessed to reduce the gap. Before installation, apply even sealant on each connection surface and press it tightly. leak.

2. For the bearing cover of the shaft extension, in addition to ensuring the gap between the end cover and the joint surface of the box body, sealing elements and oil drainage plates should be added to the end cover.

3. Add a drainage plate on the inner side of the bearing close to the tank wall, so that the oil thrown on the drainage plate can be drained into the oil pool.

4. The rotation range of the drainage plate in the bearing may be very large. In order to further prevent leakage, a felt sealing ring can be added in the end cover, and the same drainage hole as the fish felt groove can be set on the end cover, even if the oil leaks Into the felt ring, the centrifugal effect can also drain it into the box through the drainage hole, thus effectively cutting off the leakage channel.

5. There is a ventilator installed on the harmonic reducer. If the vent hole is blocked, the temperature of the box will rise, the gas will expand, and the pressure will increase, which will aggravate the oil leakage. Therefore, it is necessary to ensure that the vent hole is not blocked, so that The internal and external pressure of the reduction box is balanced, which can effectively prevent leakage.

6. The increase of oil resistance will reduce the efficiency of the machine, so the amount of oil added must be appropriate, and the depth of the gear in the oil cannot exceed the height of another tooth, because the oil is stirred violently, which will increase the oil temperature and accelerate leakage.

The above article describes in detail the solution to the oil leakage of the bearing end cover of the harmonic reducer. It is worth noting that when selecting the felt ring, the size must be based on the size of the felt groove and the diameter of the shaft. Pay attention to ensure that The tolerance of the shaft and the content of the felt ring is matched, so that the oil leakage of the bearing end cover can be effectively prevented.

In daily life, oil tank truck is a very common means of transporting dangerous goods, because its transportation objects are mostly all kinds of flammable and explosive oil products, so the safe transportation of oil tanker is the key of every tanker driver. What should be paid attention to, what are the common oil tank truck faults, and how should we deal with these problems? The following is a tank truck manufacturer–CIMC LINYU, to analyze the common oil tank truck faults and solutions.

Oil Tank truck faults can generally be divided into indirect failures and sudden failures. When a failure occurs, we need to first determine the cause of the failure, and then carry out targeted treatment.

1. The oil absorption of the oil tank truck is abnormal

The reasons for the abnormal oil absorption of the tanker are generally: there is no oil in the oil pump; the oil absorption depth is more than 5m; the valve opening position is not correct. To solve this problem, we can fill the oil tank to at least 10L, and adjust the valve to the appropriate position That’s it. If the fuel tank of the tanker cannot discharge oil, it may be an impurity oil discharge pipe. In this case, just cleaning the oil pipe can solve the problem.

2. The oil tank truck cannot absorb oil or absorb less oil

The reasons for the oil tanker not being able to absorb oil or the amount of oil being absorbed are: the suction pipe part is not tightly sealed; the gap of the oil pump is increased. At this time, we only need to make the seal tight, and check and repair the oil pump.

3. The power take-off box of the oil tank truck is abnormal

The reasons for the abnormality of the power take-off box of the tanker are as follows:

(1) The pressure of the car is insufficient, and the power take-off box is not in gear;

(2) The air path is not tightly sealed, and the power take-off box is fooled;

(3) The air chamber is damaged, and the power take-off box is not hooked;

(4) Too little lubricating oil or impurities in the power take-off box;

(5) Wear of power take-off parts

For the above problems, we usually only need to have enough air in the pneumatic power take-off box, so that the reading of the air pressure gauge is above 0.6Mpa, the air circuit is strictly sealed, check the air chamber in time, refuel or update the lubricating oil, dismantle and inspect, clean and replace the worn parts. Can.
