The hard tooth surface gear reducer is mainly a type of reducer produced according to the national standard, and is mainly used for the transmission device with the output shaft arranged in the vertical direction.In industrial production, hard tooth surface gear reducers are mainly used for belt conveyors and various transportation machinery, and can also be used for transmission machinery of various general machinery such as coal, metallurgy, chemical industry, building materials, light industry, petroleum, etc. middle.Sealing requirements and functions of the hardened gear reducer: 1. No gaskets are allowed between the box split surfaces of the hardened gear reducer, but sealant or water glass can be applied to ensure the seal.2. When assembling the reducer, before tightening the box bolts, use a 0.05mm feeler gauge to check the tightness between the hard-toothed reducer case cover and the joint surface of the box seat.3. The shaft extension seal should be coated with grease, and the seals of the hard tooth surface reducer should be assembled in strict accordance with the requirements.Only when the sealing of the hard tooth surface reducer is done well can it ensure its smooth operation, prevent the oil leakage of the reducer, and effectively improve the reduction rate.

Hard tooth surface reducer is a kind of reducer, which is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other industrial sectors.The main classification focuses on two types, namely: QJY type hardened gear reducer and QY type hardened gear reducer.1. QJY type hard tooth surface reducer QJY type hard tooth surface reducer is a crane reducer with hard tooth surface (carburized and quenched tooth surface) developed by the factory according to the requirements of domestic and foreign markets, including three basic types and 12 basic types, respectively Yes: QJY2, QJYD2, QJYA2, QJY3, QJYD3, QJYA3, QJY23, QJYD23, QJYA23, QJY34, QJYD34, QJYA34.QJY series reducers are suitable for the various operating mechanisms of cranes, and are also widely used in the transmission mechanisms of various mechanical equipment such as transportation, metallurgy, mining, chemical industry, and light industry.Two, QY Read More

Precautions before installation of Taixing reducer: The installation shaft of the machine should be cleaned before use.And check whether the installation shaft has any bruises and dirt, and if there are any, they should be cleaned up.The operating temperature of the reducer is 0-40°C.Check whether the matching size of the hole connected with the reducer meets the requirements, and the tolerance of the hole should be H7.Before use, the blockage at the high position should be replaced with an exhaust screw plug to ensure that the gas in the body is discharged when the reducer is running.For the installation of Taixing reducer, the reducer can only be installed on a flat, shock-absorbing, torsion-resistant support structure.Under no circumstances is it allowed to hammer pulleys, couplings, pinions or sprockets, etc. into the output shaft, as this will damage the bearings and shaft.Operation and maintenance, after the reducer is installed, check whether it is flexible.For official use, please carry out no-load test. Under the condition of normal operation, gradually load the operation.It is strictly forbidden to use the reducer beyond the rated load.The reducer should check whether the oil level is normal before use and during operation.

The hard tooth surface reducer has been developed in our country for nearly 40 years, and it is widely used in various fields of the national economy and national defense industry.The use of hard tooth surface reducers has accelerated the growth of industries such as metallurgy, electric power, construction machinery, building materials, and power. Therefore, the market demand for reducers has gradually expanded.1. The peripheral speed of gear transmission is not more than 20 m/s.From the perspective of the development of enterprises in the industry, in recent years, private enterprises in Jiangsu and Zhejiang have grown rapidly and have become a new force in the industry.2. The working environment temperature is -40-45°C. If it is lower than 0°C, the lubricating oil should be preheated to above 0°C before starting. The gear reducer can be used to work in both positive and negative directions.They keep up with market innovations, adjust product layout in real time, and their requirements for product quality are constantly improving.

In recent years, there are many types of reducers, and reducer manufacturers of various sizes have gradually poured into the market, which has caused certain troubles for many buyers.So, how should we choose a suitable reducer manufacturer in a mixed environment? Read More

On the surface, it may seem that gears are being “reduced” in quantity or size, which is partially true. When a rotary machine such as an engine or electric motor needs the output speed reduced and/or torque increased, gears are commonly used to accomplish the desired result. Gear “reduction” spec Read More
