Description

Technical Field

[0001] The invention belongs to the technical field of gear manufacturing, and in particular relates to a device for precision grinding gears. Background Art

[0002] Gear manufacturing is a very important field in mechanical manufacturing. Gears are widely used in various mechanical transmission systems to transmit power and rotation. The processing technology of gear manufacturing includes milling, turning, grinding, hobbing and other methods. Different processing technology selection depends on the type, size and precision requirements of the gear. Fine grinding is one of the important process steps to ensure the precision, surface quality and durability of the gear.

[0003] In the prior art, a Chinese patent with the announcement number "CN114101806B" discloses an automated fine grinding device for manufacturing transmission gears of a gearbox, in which the end face gear can be driven to rotate by a reversing motor to adjust the gear teeth processed by the end face gear, and each time the gear is changed, the end face gear is driven to move up and down by the telescopic cylinder to avoid the occurrence of jamming between the gear teeth of the end face gear and the grinding unit, thereby ensuring the stable reversal of the end face gear, improving the processing effect of the gear teeth of the end face gear, and solving the following problems that currently exist in the process of processing the gear teeth of the end face gear: the end face gear is prone to shaking during the processing of the gear teeth of the end face gear, affecting the processing effect of the gear teeth of the end face gear, and the gear teeth of the end face gear are prone to collision with the grinding unit during the reversing process to cause jamming, and the problem of low efficiency in grinding the gear teeth surface of the end face gear.

[0004] However, the above device still has the following problems during implementation:

[0005] Gear grinding will produce a certain amount of debris. Due to its large surface tension, the fine powder will be adsorbed on the surface of the gear to be processed. If the debris is not removed and continues to exist in the contact area of ​​the gear gap, it will cause premature wear of the gear, especially under high speed or high load conditions, which will directly lead to a decrease in the yield rate.
