What is the purpose of gear modification?
The main purpose of gear shifting is two. One is to gather the center distance, and the two is to change the pinion gear to improve the gear strength and the tooth surface contact strength of the pinion.
Several gear purposes are: first, together with the center distance, the transmission due to gear, and restricted by space, some gear center distance need changes even for structure, the variable named displacement angle. Second, the pinion is shifted, the large gear negative displacement, and thus tend to gear life design, this change is called high displacement. Third, the size of the gear because of the structure, there is not a convenient disassembly, another convenient disassembly, easy disassembly can reduce the negative shift, the relative life is relatively fragile, the variable named high displacement. The fourth, second gears, one made of special rare metals, are expensive and can only be used to increase their life.
The main purpose of the gear to be corrected is that:1 、 apply the gear shift to reduce the size of the mechanism;2, the use of variable gear drive to improve the bearing capacity of gear;3, with variable gears to match the center distance;4. Repair the worn gear by using the gear shifting principle.
