Common fault causes and troubleshooting methods of worm gear reducer?

1. Reducer heating and oil leakage. In order to improve efficiency, the worm gear reducer is generally made of non-ferrous metal, and the worm is made of harder steel. Because it is a sliding friction transmission, more heat will be generated during operation, which will produce differences in thermal expansion between various parts and seals of the reducer, thus forming a gap on each mating surface, and the lubricating oil will become thinner due to the increase in temperature, which is easy to cause leakage.

There are four main reasons for this situation, one is that the combination of materials is unreasonable; second, the quality of the surface of the meshing friction surface is poor; Third, the selection of lubricating oil addition is incorrect; Fourth, the assembly quality and use environment are poor.

2. Worm gear wear. The worm gear is generally made of tin bronze, and the paired worm material is hardened to HRC45 55 with 45 steel, or 40CR hardened HRC50 55 and then ground to roughness by a worm grinder. The reducer wears out very slowly during normal operation, and some reducers can be used for more than 10 years.

If the wear rate is fast, it is necessary to consider whether the selection is correct, whether it is overloaded, and the material, assembly quality or use environment of the worm gear.

3. The transmission small helical gear is worn. It generally occurs on vertically installed reducers, which are mainly related to the amount of lubricating oil added and oil varieties. When the reducer stops running, the transmission gear oil between the motor and the reducer is lost, and the gear can not get the due lubrication protection.

When the reducer starts, the gears are not effectively lubricated, resulting in mechanical wear and even damage.

4. The worm bearing is damaged. In the event of a failure, even if the gearbox is well sealed, it is often found that the gear oil in the reducer is emulsified, and the bearing is rusted, corroded, and damaged. This is because after the reducer has been running for a period of time, the condensate produced after the gear oil temperature rises and cools down is mixed with the oil.

Of course, it is also closely related to the quality of the bearing and the assembly process.

Reasons for slippage: First, the matching accuracy of the reducer input shaft hole and the servo motor shaft is not enough, and the second is that the unilateral bolt is fixed, and the row differential balance is not reached. The solution is to replace the reducer input shaft hole.

The input shaft hole of our Zhuochuang Transmission Chunchan adopts an integrated design, and the twin bolts of the gear are symmetrically distributed to achieve dynamic balance, and at the same time, the motor shaft is effectively prevented from slipping through the double bolts, and the power transmission with high precision and zero backlash is realized.

Summary. What is the cause of worm gear reducer track slippage.

Hello dear, 1. The belt model does not match the center distance, that is, the belt is too long.

2. The wrapping angle of the small pulley is too small, and the friction cannot be reached.

3. The load is too heavy.

If the adhesion of the car tires is insufficient, slippage will occur. The method of coping with front wheel slippage depends on the front wheel or rear wheel drive; Depending on the method of coping with rear-wheel slippage or rear-wheel drive; There is no difference in how to deal with rear wheel slippage. The most "natural" response to skidding is to slam on the brakes, which is actually the most dangerous.

What to do after slipping.

When the rear wheels slip, the rear of the car slides to one side, and even the body spins violently. This often happens when driving into a curve at a speed that is too high. Driving on smooth, rough or high arch roads, the brakes are too hard and the rear wheels will slip.

Rear wheel slippage is the most prevalent in front-wheel drive cars. Whether it's a front-wheel drive or a rear-wheel drive car, the way to deal with it is the same.

What is the cause of worm gear reducer track slippage.

This often happens when driving into a curve at a speed that is too high. Driving on smooth, rough or high arch roads, the brakes are too hard and the rear wheels will slip.

The frequent failure or short service life of the pro-worm gear reducer may be due to the following reasons:1Excessive load:

The worm gear reducer can only withstand the specified rated torque, and if the load is too large, it will accelerate the wear and damage of parts, which will lead to a significant reduction in the life of the reducer in serious cases. 2.Potential structural issues:

Some reducers have structural defects in the design or manufacture, such as improper coordination of worm gear and worm, insufficient elasticity of the transmission chain, etc., which will lead to various faults and affect the service life under long-term use. 3.Potential Material Issues:

The engineering plastics or alloy materials selected for some products have poor strength and wear resistance, cannot effectively withstand long-term working loads, are easy to wear and deform, and will break in serious cases. 4.Improper maintenance:

If you use it for a long time without any maintenance, the grease and dirt will accumulate, and the moving parts will be seriously worn but not replaced in time, which will greatly reduce the service life of the reducer and cause frequent failures. 5.Harsh environment of use:

In the dusty, high humidity, vibration and temperature drastic use environment, the reducer is prone to various failures, and the service life will be short. It is necessary to choose a product with a high level of protection. The measures to change Zen and return to good grasp are as follows:

1.Choose a reducer with appropriate rated torque and speed, and avoid overload. 2.

Choose products with reliable quality, reasonable material and structural design. You can choose a product with a higher level of protection. 3.

Increase maintenance, regularly inspect lofts and replace worn and damaged parts in a timely manner. 4.Select the appropriate protection level according to the harshness of the use environment, and carry out additional protection if necessary.

5.Ensure that the input and output axes of the reducer are properly aligned to minimize stress concentration and vibration. 6.

Use grease or liquid wisely to ensure that the moving parts are fully lubricated. Replace the grease during the fixing period.
