Under what circumstances is the reducer easy to be burned: Due to improper operation or carelessness in daily use, the reducer circuit will be abnormal and burned. What aspects should we pay attention to. 1. Long term overload and incorrect power selection will cause the machine itself to heat up, and the reducer will burn out after a long time. 2. Repeated operation is harmful to the reducer. When the reducer is opened and closed, the current is very large. Long term repeated operation is the cause of the reducer burning. ...

JZQ reducer JZQ reducer is widely used in hoisting, mining, chemical, textile, cement, transportation, pharmaceutical and environmental protection enterprises. ZQ is an involute cylindrical gear reducer, and ZQH is a single circular arc cylindrical gear reducer. Their overall dimensions, shaft extension assembly model, and installation dimensions are the same. JZQ series cylindrical gear reducer models include: 2503504005006507508501000 JZQ series cylindrical gear reducers have transmission ratios of 48.57, 40.17, 31.5, 23.34, 20.49, 15.75, 12.64, 10.35, 8.23 JZQ series cylindrical gear reducer has three shaft outlet forms: cylindrical shaft end, F is cross block shaft end, and C CA is tooth shaped shaft end Measurement of reducer temperature: The manufacturer shall test the temperature of the reducer at the position where the thermometer can contact the lubricating oil. As we all know, the reducer will slightly heat up after a period of operation during use. Although it is a normal phenomenon, it cannot always be heated. In order to test the accuracy of the results, the operating temperature and ambient temperature should be tested first. 1、 Determination of working temperature The temperature rise of the reducer is usually measured at the same time as its bearing capacity and transmission efficiency, or separately. When the reducer under test meets the requirements, the operating temperature at rated speed and rated input power is read. 2、 Environment 
GN (DTII) roller backstop GN (DTII) roller backstop is suitable for head pulley. It is driven by reducer. The belt conveyor with larger power, larger drum diameter and reducer above ZQ65 is more suitable for upward conveying. The inclination angle is ≤ 18 degrees. Its advantages are rapid backstop and small reverse distance. It is a backstop for large and medium-sized inclined conveyors. It is widely used in reducer matching, coking plant and transportation machinery, conveyor, elevator, electric drum and other mechanical equipment requiring backstop requirements. National regulations: The terms, basic parameters, technical requirements, test methods, inspection rules, marks, packaging and storage of backstop are specified in the backstop for belt conveyors JB/T 9015-1999 issued by the State Bureau of Machinery Industry on June 28, 1999 and implemented on January 1, 2000. Inner circle rotation direction - the direction that can rotate freely in the backstop. When looking directly at the steering indicator, the inner circle rotates clockwise with the code of S and counterclockwise with the code of N. 
ZLY hard tooth surface reducer ZLY series hard tooth surface reducer is an external involute helical cylindrical gear reducer manufactured according to the national standard JB/T8853-2001. This product is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields. The applicable range of the reducer is as follows: 1. The high-speed shaft speed is not more than 1500 rpm. 2. The peripheral speed of gear transmission is not more than 20m/s. 3. The working environment temperature is - 40~45 ℃. If it is lower than 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting. The reducer can be used for operation in both positive and negative directions. Boundary Dimensions of ZLY Series Hard Toothed Surface Reducers JB/T8853-2001 Requirements of reducer for lubricating oil: The normal use of the reducer is inseparable from the lubricating oil, and good lubrication is to ensure its better operation. However, there are certain requirements for the selection of lubricating oil before the lubrication of the equipment. Next, I will give you a detailed introduction. 1. Good abrasion resistance Wear resistance refers to the ability of reducer lubricating oil to form and maintain an oil film on the friction surface between moving parts, prevent metal to metal contact, and reduce wear. The anti-wear property of lubricating oil mainly depends on its oiliness and compressibility (shear resistance). Oiliness refers to the ability of gear oil to form oil film on the friction surface of parts to reduce friction and wear. Usually, when we say that gear oil has good oiliness, it means that it has strong adsorption capacity and can improve the anti-wear ability. Compressibility means that the contact pressure on the friction surface is very high, and the oil film is easy to break
