Used For Agricultural Machinery Accessories Gears
Product Description
A very important part of agricultural machinery is gears. In agricultural machinery, gear transmission is the most important transmission mode. There are many factors that affect gears. From the overall composition, there are mainly gearboxes, bearings and shafts. In terms of the manufacturing accuracy and assembly accuracy of the parts, the design of the parts is related to the selection of materials and heat treatment, and the use is related to the maintenance and lubrication of the gears. The gear transmission rate of agricultural machinery is relatively large, and it often runs under heavy load and low speed. The working conditions are relatively harsh, and the maintenance is not standardized enough, which can easily lead to gear transmission failure and failure.
First of all, the problems that should be paid attention to when installing the gear:
When installing the gear, check the backlash and the end face swing of the gear. The gear clearance should ensure the minimum clearance under the condition of ensuring smooth transmission and no jamming. Excessive clearance can easily cause transmission shock and noise, and it is easy to damage the gear. Excessive swinging of the end face of the gear will cause the transmission to be unstable and the phenomenon of tooth punching.
In addition, other inspections are also necessary, which are of great help to the installation. To check the backlash, measure its thickness with a thickness gauge or with a lead piece passing between the meshing gear teeth.
Use the imprint method to check the meshing parts of the gears and the installation quality of the gears. Proper meshing is where the color length of the impression is not less than 70% of the length. The width is not less than 50% of the tooth height, and it is required to be at the middle pitch circle position of the tooth. Various impressions can roughly reflect the quality of the installation.
The Correct Maintenance Method Of The Transmission Gear
1 Choose the correct lubricant
In the transmission of gears, lubricating oil is an indispensable lubricating medium, which can protect the gear teeth and avoid damage. The transmission gear has special requirements on the viscosity of the lubricating oil. If the viscosity is too low, the protective film will not be formed, and the meshing surface of the gear teeth will not be protected. If the viscosity is too high, the transmission gear will lose friction and the temperature will be too low. can't start up. In addition, in the case of high-speed operation under heavy load, the oil temperature on the surface of the gear is too high, which can easily lead to oxidation and deterioration. In the case of high temperature, the gear oil has good anti-oxidation and stability properties, and must use standard lubricating oil to ensure the gear oil. of antioxidant properties.
2 Make sure the gear surface is clean
When using agricultural machinery and large-scale agricultural equipment, it is necessary to avoid overloading and ensure the sealing of the gear transmission system, thereby preventing hard objects and dust from entering the gear box.
3 Replacement parts should choose original parts
Due to different processing methods, production standards and selected materials, the non-original parts cannot meet the requirements of the factory parts, and the original effect cannot be achieved after maintenance, and it is very likely that there will be failures during use. When selecting gears, be sure to pay attention to the roughness of the gear surface. Relevant studies have found that the roughness of the gear surface at low speed and heavy load will cause greater wear on the surface of the gear, and the higher the roughness of the initial part surface. The probability of wear is also higher, be sure to choose gears with smooth surfaces.
