For maintenance of JS gear reducer gears after they are worn, it is necessary to choose an appropriate treatment plan based on the severity of the wear. It can usually be divided into three situations: mild, moderate and severe wear: 1. Repair of mild wear If there are only slight scratches, burrs or excessive surface roughness on the tooth surface, but it does not affect the overall meshing accuracy, the following methods can be used: Grinding and polishing: Use oilstone, sandpaper or polishing machine to finely grind the tooth surface to remove burrs and tiny defects and restore the smoothness of the tooth surface. Note: The pressure must be controlled during the grinding process to prevent excessive wear from causing changes in tooth shape. After repair, it is necessary to check the distribution of contact spots on the tooth surface. 2. Repair of moderate wear. If the tooth surface has local wear, peeling, or even wear but has not damaged the core structure of the gear, the following methods can be used to restore size and performance: Overlay welding repair: first remove the oil and rust in the worn area, and select a material that matches the base material.

After the JS gear reducer gear is worn, no matter which repair method is used, reassembly and debugging are key steps to ensure the quality of repair: 1. Adjust meshing accuracy: The contact area and tooth side clearance of the gear must be carefully adjusted during assembly (usually the tooth side clearance is between 0.15-0.40mm, specifically determined according to the module) to ensure correct gear meshing and extend service life. 2. Sealing treatment: The processing joint surfaces of the upper and lower boxes should be thoroughly cleaned, apply a layer of oil-resistant sealant evenly, and then tighten the bolts evenly in diagonal order to prevent oil leakage. 3. Add lubricating oil: Inject the specified type of industrial gear oil (such as No. 150 industrial gear oil). The amount of oil is usually suitable for immersing 1/3 of the large arc bevel gear or reaching 1/2 to 2/3 of the oil level window. 4. No-load and load tests: (1) No-load test operation: Let the reducer run without load for about 30 minutes, and observe whether the operation is stable, and there must be no impact, Read More

To ensure the sealing of the FAB series planetary reducer in a dusty environment, systematic considerations need to be made from four levels: design, structure, protection and maintenance. The following is the specific implementation strategy: 1. Selection stage: When it is clear that the high protection level is Selection, the first task is to clarify that the reducer must have high standards of protection capabilities. Specify IP protection level: Make it clear to the supplier that you require a model with a high level of protection. Standard models are usually IP54, but for dusty environments, priority should be given to selecting or customizing reducers with IP65 or higher ratings to ensure they have excellent dust-proof capabilities. Confirm sealing configuration: In the technical agreement, the reducer is required to adopt a reinforced sealing configuration. This usually includes: Shaft end seal: Double lip fluoroelastomer skeleton oil seal. Fluorine rubber has excellent oil resistance, aging resistance and chemical corrosion resistance, and the double-lip structure can provide double protection to effectively prevent dust intrusion and lubricant oil leakage.

When Selection worm gear reducer, confirm that its self-locking function cannot be generalized, because not all worm gear reducers have reliable self-locking capabilities. You can follow the following steps to confirm: 1. Step 1: Consult the product manual. This is the most direct and reliable method. Regular manufacturers' product manuals usually clearly indicate whether the reducer has a self-locking function. Direct marking: Look for clear instructions such as 'with self-locking function', 'reverse self-locking' or 'static self-locking'. Parameter annotation: If there is no direct explanation in the manual, you can look for the parameter 'worm lead angle (λ)'. Generally, reducers with a lead angle less than 5° (especially less than 4°) are more likely to be self-locking. 2. Step 2: Judge through core parameters. If the manual information is incomplete, you can evaluate the possibility of self-locking through the following core parameters. The fundamental principle of self-locking is: the lead angle (λ) of the worm must be smaller than the worm gear mesh Read More

The center distance of the DBY type hardened bevel cylindrical gear reducer is selected not through free calculation, but based on the design requirements and from the standard specifications of this series of reducers Selection. The center distance is a core specification parameter of the reducer. The center distance of the DBY series reducer has been standardized. 1. DBY series standard center distance specifications There are 12 specifications of DBY reducer. The nominal center distances (referring to the center distance of the final cylindrical gear) are: 160, 180, 200, 224, 250, 280, 315, 355, 400, 450, 500, 560 mm 2. Detailed Selection Steps The detailed steps for selecting the appropriate center distance are as follows: 1. Determine the basic design parameters. First, it is necessary to clarify the specific working conditions and requirements of the reducer application, and collect the following key parameters: Input power (P): The motor power that drives the reducer, in kilowatts Read More

The SBD reducer makes abnormal noise when restarting after a long period of shutdown. This is usually caused by lubrication, corrosion or assembly problems. Please follow the steps below to troubleshoot and resolve the system. Important: Before performing any inspection or repair, be sure to cut off the power supply and ensure that the equipment comes to a complete stop to prevent safety accidents. 1. Steps to troubleshoot and deal with abnormal noise 1. Check the oil level and oil quality of the lubrication system: First, check whether the oil level of the lubricating oil is within the normal range (usually 1/2 to 2/3 of the oil window). Long-term shutdown may cause the lubricating oil to deteriorate, increase in viscosity, or be mixed with impurities, which will seriously affect the lubrication effect and cause abnormal noise due to dry grinding of gears and bearings. Treatment measures: If insufficient oil is found, the oil is black, turbid or has sediment, it should be replaced immediately with new lubricating oil that meets the specifications. It is prohibited to mix lubricating oils of different brands and models. 2. Manual turning inspection operation method: In the power-off state, try to Read More
