Ball Mill Pinion Gear needs to be very finely processed, and every process needs to pay attention to any details, without any defects.
Moreover, there are strict standard requirements for the running-in degree of the ring gear, and it needs to be strictly tested after processing before it can leave the factory.
After some unique heat treatment technology, the wear resistance of the ring gear can be improved, and a certain hardness can also be enhanced. It can have wear resistance and impact resistance during use, and prolong its service life during use.
With the continuous development of domestic science and technology, the technology of all walks of life has been improved now. Mill Girth Gear can often be seen in people’s lives, and it is also one of the main components of some equipment.
Such as rotary densities and ball mills and other equipment.
Among them, the ring gear in the rotary density is a very important part. The quality of the installation directly affects the stability of the transmission of the equipment system. Therefore, there are strict requirements in the production process. Then we will explain the large ring gear for you. manufacturing process.
Due to the high precision of the segmented ring gear, grinding must be performed first.
1. Ensure the runout of the positioning stop relative to the pitch circle
2. Ensure that each tooth can be ground
3. Ensure that the grinding amount is as small as possible to avoid excessive grinding of the quenched layer.
4. The roundness of the ring gear after splicing is particularly good, and the cutting seam is uniform at the same time
To meet the above requirements, to align the positioning stop, and grind the teeth. By synchronizing the tooth grinding accuracy with the accuracy of the outer circle alignment belt (installation reference), the assembly accuracy and efficiency can be improved, the gear accuracy loss caused by the indirect pitch circle alignment during installation is avoided, and the installation accuracy of the large ring gear is effectively guaranteed. .
The process and process guarantee of Ball Mill Pinion Gear processing, and the difficulties of normal segmented ring gear, are reflected in the following aspects
1. The accuracy of the gear is guaranteed, the length of the common normal line, the tooth jump, the roughness of the gear, as well as the tooth direction and tooth shape.
2. Gear deformation, difficult to control, expansion deformation, warping deformation, and various parameters after gear segmentation are no longer under control.
3. The processing of segmented large gears, tooth processing, tooth surface quenching, and grinding, all need to be fixed on the tire.
4. In the process of preparation, ensure that it is necessary to prevent deformation before and after heat treatment, tooth processing, and segmentation.
This is the top priority of this process. Many factories cannot meet the quality requirements after processing during the processing process, and most of the indicators are out of tolerance and have to be scrapped.
The processing technology of the segmented large ring gear, as well as the budget process, ensure that the processing process is always under control, the processing process is complete, and it cannot be directly segmented after tooth processing, otherwise the gear parameters, gear expansion deformation, and warping deformation cannot be guaranteed.
Through the optimization of processing technology and the design and application of special tooling, the accuracy error caused by the transfer of the reference plane during finishing is minimized, and the machining accuracy of each process of the ring gear is preserved to the limit.
Summarize the processing technology of the segmented large ring gear, as well as the budget process, to ensure that the processing process is always under control, the processing process is complete, and it cannot be directly segmented after the tooth processing, otherwise the gear parameters, gear expansion deformation, and warpage deformation cannot be guaranteed.
Stress relief is a key part of it, ensuring thermal insulation and stress relief in every process.
