Miter Gearbox Quality Is More Stable
The gearbox is the role of matching speed and transmission torque between the prime mover and the working machine. Therefore, the normal operation of the gear box affects the normal operation of the whole system, Miter Gearbox and its various aspects of the characteristics are also important. Miter Gearbox At present, the domestic production of mechanical products with foreign machinery products, there are still gaps, these gaps are mainly reflected in the basic components, such as hydraulic components, large capacity and low performance, Miter Gearbox serious leakage of oil. While the introduction of foreign mechanical products, the quality of the hydraulic system is more stable, after a long period of use of small oil leakage. Because of the lack of attention to mechanical products and production process of cleanliness caused by poor quality, low product delivery rate, short life and other issues. Miter Gearbox Domestic introduction of foreign advanced technology at the same time, not on the product processing and assembly process cleanliness caused enough attention, resulting in the same technology, but the performance of the product produced with a lot of difference from abroad. Miter Gearbox The cleanliness of the gear box is mainly reflected in the parts in the process of assembly and assembly of iron and other impurities, lubricating oil cleanliness and other issues. Miter Gearbox The cleanliness problem is simple, but the problems or failures are multifaceted. The following is a description of the reasons for the cleanliness, the impact and improvement.
(1) The clarity of the lubricating oil used in the gear box is poor. This is the direct cause of poor cleanliness. The main consequences are: when the gearbox starts to run, the lubricating oil enters the lubrication line to each lubrication point (generally the gear meshing area and the bearing area), where the impurities also reach the meshing zone and the bearing, thus affecting Their service life. Therefore, Miter Gearbox it is recommended that you use a special oil filter to filter before using the lubricant.
(2) parts of the machine produced when the iron is not clean. Miter Gearbox On the one hand is the next process of processing workers due to careless parts of the iron to clean up, resulting in the surface of the parts of the pit or scratches and other defects; the other is the presence of iron in some locations is not easy to clean, such as (See Figure 1) The iron filings in the gear box after the work will be through the oil into the work area, and then damage to the parts.
(3) pickling after the oil and welding and other processing. Miter Gearbox After the acid pickling circuit is not allowed to be welded, or welding impurities will enter the pipeline, and with the oil into the gear box cycle.
(4) assembled on the finished product for some parts of the post-processing processing. Principle with (3).
(5) after cleaning the parts do not pay attention to preservation, Miter Gearbox free to put. Such as dust and other impurities into the important parts of the parts, affecting the size of the fit.
(6) poor sealing effect. From the design considerations, you can use the input and output shaft V-type dust seal; from the processing point of view, you can improve the surface roughness of the shaft.
(7) paint can not withstand high temperatures. When the gear box in high temperature conditions, Miter Gearbox the box wall paint can not withstand high temperature, paint peeling fall into the lubricating oil; box outside the wall of the paint affect the appearance.
(8) sealant falling box. When the gear sub-box surface or other bonding surface smear sealant too much, Miter Gearbox when the box or lid, the sealant will be squeezed into the box, into the oil
