The output speed of SA47-15-1.5KW worm reducer is 'Transmission ratio''Motor input speed''Actual operating condition loss' It is determined by three core factors, among which the transmission ratio and motor input speed are the basis for theoretical calculation, and the working condition loss is the correction term in actual operation. The following is a disassembly analysis of specific influencing factors, combined with model parameters ('SA47' is the frame number, '15' is the nominal transmission ratio, '1.5KW' is the matching motor power) Explanation: 1. Core determinants: transmission ratio ('fixed coefficient' of theoretical output speed) The output speed of the worm reducer is essentially 'motor input speed ÷ transmission ratio', where the transmission ratio is fixed and determined by the mechanical structure of the reducer (number of worm heads, number of worm gear teeth), and is the core and most stable factor affecting the output speed. 1. Definition and calculation of transmission ratio Logical transmission ratio (i) is the reducer Read More

The operating loss of the SA67AM90-85.83-M1 worm reducer mainly includes the following aspects, and its mechanism of action is closely related to the characteristics of the worm gear transmission: 1. Mechanical friction loss 1. Tooth surface meshing friction When the worm meshes with the worm gear, the sliding friction coefficient is usually 0.08-0.12‌1, and friction loss accounts for 60%-70% of the total power. The equivalent friction angle (ρ) is directly related to the material combination (such as steel worm + bronze worm gear) and lubrication state. 2‌. Bearing friction loss‌ The friction loss of the worm shaft and output shaft bearing accounts for about 15%-20%. The friction coefficient of the deep groove ball bearing is 0.001-0.003. If the lubrication is poor (such as oil temperature >80℃) or the load exceeds the rated value, the loss can increase by 30%‌. 2. Fluid power loss ‌ Oil stirring loss ‌ The energy consumption caused by the stirring of lubricating oil by rotating parts accounts for 5%-10%, which is proportional to the depth of the oil pool, oil volume and the square of the rotation speed. example Read More

Common faults of the TPU315-25-1 worm gear reducer (center distance 315mm, transmission ratio 25) are mostly related to 'lubrication failure, load overload, installation deviation'. The treatment must follow the principle of 'first locate the fault point, and then solve it in a targeted manner' to avoid blind disassembly. Combined with its structural characteristics of large center distance and medium speed ratio, common faults can be divided into 4 categories. The specific manifestations, causes and treatment methods are as follows. 1. Fault 1: Abnormal operating noise (piercing noise, metal friction sound). This is the most easily detectable fault. It is mostly related to component wear or misalignment. If not handled in time, the damage will be aggravated. Common reasons: The worm gear is severely worn (tooth surface peeling, uneven tooth thickness), resulting in excessive meshing clearance or abnormal bite. The bearing is damaged (the rolling elements are worn, the cage is broken), and irregular vibration and noise are produced during operation. The concentricity deviation between the motor and the reducer, the reducer and the load is too large (more than 0 Read More

The impact of magnetic anomalies on the service life of the H3SH14 industrial gearbox is difficult to accurately quantify, but it may shorten its service life by 20%-50% or more, which mainly depends on the type and severity of the magnetic anomaly, the working environment of the gearbox and other factors. Magnetic anomalies usually affect the service life of the gearbox in the following ways: Leading to increased component wear: Magnetic components inside the gearbox (such as gears, bearings, etc.) may have residual magnetism during processing or testing. If magnetic anomalies lead to residual magnetism on the gear surface, magnetic particles such as iron filings in the oil will be absorbed. These particles act like abrasives and will intensify the wear of the gear tooth surfaces and bearing raceways. For example, normally a gearbox gear can be used 5 years, but in the case of magnetic abnormalities that are not handled in time, serious tooth surface wear may occur in 2-3 years, leading to gear failure. Causing increased vibration and noise: Magnetic anomalies may Read More

Reduce GSA77-Y3-4P-75.2-4KW worm reducer ('GSA77' is the frame number, 'Y3-4P' is a high-efficiency 4-pole motor, '75.2' is a precise transmission ratio, '4KW' (Rated power)), it needs to be combined with its characteristics of large transmission ratio (75.2), medium and high power (4KW), and high-efficiency motor adaptation, from the five dimensions of 'load optimization, lubrication upgrade, precise installation control, environmental protection, and operation monitoring' to solve core problems such as 'prominent sliding friction in large transmission ratios, concentrated heat generation in medium and high power, and high matching accuracy requirements for motors and reducers.' The following are specific measures that can be implemented: 1. Core direction: optimize load matching and reduce 'overload and impact losses' from the source. The rated output torque of GSA77-4KW is about 300~400N·m (refer to the manual), large transmission ratio (75.2) Read More

The alarm and shutdown threshold settings of the WPDKA80-40-1.5KW worm gear reducer need to comprehensively consider the operating parameters, load conditions, and manufacturer's recommendations of the equipment. The following are some common setting methods and reference values: Vibration threshold: The vibration status can be monitored by installing an acceleration sensor on the reducer housing. Generally speaking, the early warning value of vibration speed can be set to 4.5mm/s, when the vibration speed is greater than or equal to 11.2mm/s , it should be set as the shutdown threshold. You can also refer to the vibration intensity. Six times the safety limit is the allowable limit. When the detection value is greater than 80% of the allowable limit, shutdown for maintenance should be considered. Temperature threshold: It is usually necessary to monitor the oil temperature of the reducer and the bearing temperature. The alarm threshold of oil temperature can be set to 70°C. When the oil temperature reaches 90°C, it should be set to the shutdown threshold. For bearing temperature, the alarm threshold can be set to 85° Read More
