The noise of reducer is caused by the periodic change of the force of change caused by the gear tooth in the human body during the whole operation process on the rolling bearing and the housing. The noise value of the reducer is an important standard of its quality level. With the intelligent of national standard of commodity, the noise value of reducer is also regulated strictly. The following is a discussion on the noise causes and treatment of the reducer, which is only for the reference of the group.
1. The harm of machining precision of cover hole to noise of reducer the accuracy of shell hole refers to the accuracy of diameter, error of center moment, flatness and inclination of motor reducer at the center line of each hole. The clearance between the two sides of the rolling bearing and the bore of the reducer housing is very important to the noise of the rolling bearing. When the clearance between the hole and the rolling bearing is less than or equal to 0.01mm, the noise damage of the rolling bearing to all the machine equipment can be reduced.
2. The harm of gear shaft production and processing to the noise of reducer the overall design of gear design is particularly important to noise. The design scheme is to improve the bending strength of gear, adopt large displacement mark value and appropriate spiral angle to improve the gear joint standard value and ensure the purpose of reducing noise. Compared with the Huaihe commodity series transmission reducer, the manufacturing accuracy of gear lies in its noise value. The impact accuracy of gear is harmful to noise. The comprehensive index to evaluate the precision of gear contact is to touch black spot, and the noise of hard gear reducer gear of R series helical gear must be high.
3. The harm of installation precision to noise installation quality has immediate harm to noise control of reducer.
Therefore, the following three points shall be paid attention to in all installation equipment: ① all gears are normal, ensuring the backlash of gear, high quality of motor shaft teeth, paying attention to the fixed parts of precise positioning, avoiding the vibration and swing of internal thread of gear. ② When installing rolling bearing, it is necessary to avoid improper knocking, and avoid collision during the whole process of rolling bearing transportation and installation. ③ Remove the pre-made components of the reducer drive device according to the requirements, and avoid bumps and trips to the pre manufactured components of the transmission device during the whole installation process. The manufacturing accuracy and installation accuracy are two important reasons for noise caused by the reducer. Only by improving the production and manufacturing process, designing and developing excellent machining and manufacturing process and strictly implementing the relevant regulations of standard Huaihe machine can the quality of reducer be improved and the service life can be improved.
