The adjustment of the blade structure of the gear hobbing machine mainly includes three main steps: adjusting the pitch, gear, and guide.

Adjust pitch

Pitch adjustment is the first and most critical step in the debugging of gear hobbing machines. The pitch is directly related to the gear module, and it is 

necessary to calculate the pitch according to the required gear module of the product, and then adjust the gear to the corresponding position.

If the hobbing machine is not a new machine, it is necessary to check the wear of the hobbing gear and replace it if necessary.

Adjust gears

The gear of the gear hobbing machine is an important component to ensure the correct tooth profile and needs to be matched with the working load, that is, 

the modulus and number of teeth of the gear must be matched with the working load. If the gears are not properly matched, there may be incorrect tooth profiles, which can affect product quality.

Therefore, when debugging the gear of the gear hobbing machine, attention should be paid to whether the parameters such as the modulus and number of teeth of the gear match.

Adjust direction

Guidance adjustment is the final step in the debugging of the gear hobbing machine. Guidance affects the accuracy of the cutter, so it is necessary

 to adjust the guidance to ensure that the position and direction of the cutter are accurate. Attention should be paid when adjusting the direction,

The position and direction of the guide must meet the design requirements of the blade, otherwise incorrect tooth profile may occur.

Power on preparation and inspection

Before starting up, it is necessary to obtain a dispatch ticket, and according to the dispatch ticket, obtain drawings, processes, and prepare the required fixtures, hanging wheels, cutting tools, etc. 

Check the position of the operating handle and the position of each button and knob on the electrical control panel.

After connecting the power, check whether each lubricating oil circuit is unobstructed and adjust the oil volume of each lubricating oil circuit to the appropriate position.

 Jog the spindle to check the direction of rotation of the crankshaft, gradually increasing the speed for idle running.

Background information and precautions

The design and adjustment of the cutting mechanism of the gear hobbing machine are crucial for improving production efficiency and product quality.

 Some new designs of blade adjustment mechanisms, such as oblique blade adjustment mechanisms and conjugate dual cam blade adjustment structures,

By driving the ball screw and nut with a motor to replace bulky manual operation, not only can the labor intensity of operators be greatly reduced and production efficiency improved, 

but the structural design is also simple and easy to assemble.
