Problems solved by technology

[0003] The processing of conventional gears is usually carried out in accordance with the accuracy grade of the national standard. According to the requirements of use, all the accuracy can meet the design requirements. For individual gears with special needs, the method of improving the gear accuracy can be used to meet the requirements. The corresponding production cost of improving the gear accuracy is times up

Embodiment

[0021] In this example, the teeth of the large and small gears of the electric scooter are modified to reduce the noise of the gear pair. The modification of the pinion is mainly to modify the helix of the tooth part. The modification scheme is as follows: figure 1 Shown: In the direction of the helical line of the tooth surface, outside the control of the total helical line error, the amount of drumming is gradually gentle in the middle of the helix line to 0-0.006mm,

[0022] The modification of the large gear is mainly to modify the helix and tooth profile of the tooth. Helical line modification scheme such as figure 2 Shown: In the direction of the helical line of the tooth surface, except for the control of the total helical line error, the 80% area in the middle of the helix line is gradually gentle and the drum shape repairing amount is 0.012-0.018mm; the tooth profile modification scheme is as follows image 3 Shown: It is on the tooth profile surface, from the mesh...

Abstract

The invention discloses a machining method for reducing gear noise of an electric scooter. The method comprises the following steps that a main gear and a pinion of the electric scooter are shaped toachieve the purpose of reducing the noise of a gear pair, a spiral line of a toothed part is shaped during pinion shaping, and a spiral line and tooth profile of the toothed part are shaped during main gear shaping. According to the method, the main gear and the pinion of the electric scooter can be shaped, the contact friction surface of the tooth surfaces of the gear pair during moving is reduced on the premise that the manufacturing cost is not increased, parts producing interference are reduced, the transmission balance is improved, and the purpose of reducing the noise of the gear pair isachieved. The method is especially suitable for low-cost products, but in the case of aged electric scooters with severe requirements on gear transmission noise, the noise of the aged electric scooters can be reduced, and the comfort of the aged electric scooters is improved.

Description

technical field [0001] The invention relates to a processing method for reducing the gear noise of an electric scooter, and belongs to the technical field of gear processing. Background technique [0002] With the continuous improvement of people's living standards and the aging of China's population, the demand for electric scooters is increasing, and the product categories are becoming more and more abundant. Electric scooters are most commonly used in homes, quiet residential areas and leisure places, and are most used by the elderly and people with limited mobility. Due to the particularity of the users and the environment, the requirements for the noise and vibration of the product are relatively high. Gears are one of the core components of electric scooter, and their transmission noise and vibration directly affect the comfort of scooter users. Therefore, it is necessary to study the processing method of reducing the gear. [0003] The processing of conventional ge...
