Many friends can't tell the difference between a reducer and a motor. In fact, they are still very different. A reducer refers to a reducer and a motor, that is, an integrated body of a motor. This integrated body is usually called a gear motor or a gear motor.Geared motors have high technical requirements and high technological content. They are usually used in steel, machinery and other industries: the geared motor is a relatively precise machine. As the name implies, its purpose is to reduce the speed and increase the torque.The types of reducers and geared motors are also divided into various types. The reducers are divided into vertical direct-type gear reducers, vertical double-shaft gear reducers, horizontal direct-type gear reducers, and horizontal double-shaft gears. Reducer: The reducer motor is divided into three-phase asynchronous motor, horizontal three-phase gear reducer motor, and vertical three-phase gear reducer motor, which can be selected according to needs.The geared motor is characterized by simplified structure, space saving, reliability and durability, and high overload capacity. The geared motor adopts a new type of sealing device, which has good protection performance. Read More

Now there are various types of reducers on the market. Today, let’s talk about the difference between single-stage reducer and double-stage reducer.Single-stage reducer is also called single-stage reducer. It can be divided into single-stage worm gear reducer, single-stage gear reducer and single-stage RV reducer. The installation type is divided into horizontal type and vertical type.Double-stage reducer, also known as double-stage worm gear reducer, is divided into two-stage cast iron worm reducer and double-stage RV worm reducer. Compared with single-stage reducer, it has one more transmission device.The single-stage reducer is composed of a gear or a worm gear transmission. The latter is a single mechanism that is used to transmit the power of the prime mover to the working machine and make the working machine work at the required speed.The double-stage reducer has an additional intermediate transition gear. The left side of the driving vertebral gear meshes with the bevel gear of the intermediate gear. The bevel gear has a small-diameter spur gear on the same axis, and the spur gear meshes with the driven gear.Single-stage reducers are widely used in many fields, including transportation Read More

1. Selection of lubricating oil When the peripheral speed of the high-grade gear in the reducer is greater than 2.5m/s, or when the ambient temperature exceeds 35-50 degrees Celsius, it is recommended to use No. 320 medium-duty industrial gear oil.If the reducer manufacturer has requirements or other regulations for the oil used in the reducer, it should be selected according to the requirements or regulations of the reducer manufacturer.2. Replacement of lubricating oil After 300-600 hours of operation for the first time, the lubricating oil should be replaced.After that, replace the lubricating oil every time the reducer works for about 4000 to 6000 hours.3. The starting oil supply reducer has been placed for more than one day (that is, the time without working state) and it is a reducer that starts with full load. It should be lubricated with circulating oil, and the lubricating oil should be supplied to the place that needs to be lubricated before starting.If it is oil-immersed lubrication in the oil pool, it is recommended to manually supply the upper half of the gear with lubricating oil from the window before starting.Fourth, the size of the oil injection Read More

Worm gear reducers are active in various mechanical rotation systems. They can be used in large power transmission, small loads, and precise angle transmission, such as ships, automobiles, locomotives, and heavy-duty vehicles for construction. Machine tools, processing tools and automatic production equipment used in the machinery industry.Another point is that the worm gear reducer has many models, and different models correspond to different production environments. The relevant staff will more or less encounter certain problems in the equipment during normal operation, such as how to solve the fatigue production of the reducer , first of all, we need to know the reason, and then we can solve it in a more targeted manner.Long-term fatigue production may cause wear and damage. How is this caused?One is due to the quality problems that occurred during the manufacturing process of the reducer, and the other is that the process equipment Selection is wrong, and the thermal power cannot meet the requirements of the production process, resulting in a large load during actual operation and hidden defects gradually exposed.

The big difference between general reducer and special reducer design Selection method is that the former is applicable to various industries, but the reduction can only be designed according to a specific working condition, so users need to consider different requirements according to their own requirements when selecting. For the correction coefficient, the factory should use the actual motor power (not the rated power of the reducer); the latter should be designed according to the special conditions of the user. The coefficient that should be considered has generally been considered during the design. When selecting, as long as the power used is less than or equal to The rated power of the reducer is sufficient, and the method is relatively simple.The rated power of the general-purpose reducer is generally based on the use (working condition) coefficient KA=1 (the motor or steam turbine is the prime mover, the load of the working machine is stable, the work is 3~10h per day, the number of starts per hour is ≤5 times, and the allowable starting torque is 2 times the working torque), contact strength safety factor SH≈1, failure probability of a single pair of gears≈1%, and other conditions are calculated and determined.The rated power of the selected reducer should meet P Read More
