Cylindrical gear reducer is a power transmission mechanism that uses gear speed converters to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque.
1. Introduction
Cylindrical gear reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque.
2. Application
The gears of the cylindrical gear reducer are processed by carburizing, quenching, and tooth grinding, with high carrying capacity and low noise; it is mainly used for belt conveyors and various transportation machinery, and can also be used in the transmission mechanism of other general machinery. It has the advantages of high carrying capacity, long life, small size, high efficiency, light weight, etc., and is used in transmission devices where the input shaft and the output shaft are arranged in a vertical direction. Cylindrical gear reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields.
3. Model
(1) ZQD type cylindrical gear reducer
The ZQD type reducer is to add a high-speed stage called a three-stage transmission under the premise of not changing the position and installation size of the input and output shafts of the ZQ type reducer as much as possible, and the increased high-speed stage is at the top.
ZQD type large transmission ratio cylindrical gear reducer has six specifications: ZQD350+100, ZQD400+100, ZQD650+150, ZQD850+250 and ZQD1000+250.
(2) ZSC type cylindrical gear reducer
Based on the design and manufacturing experience of similar products at home and abroad, ZSC reducer is a series of products that have been perfected and optimized, and are widely used in metallurgy, machinery, petroleum, chemical, construction, textile, light industry and other industries.
(3) ZQA type cylindrical gear reducer
The ZQA type reduction machine is an improved design on the basis of the ZQ type reducer. In order to improve the gear carrying capacity and facilitate the replacement of the ZA type reducer, the gear shaft material is changed under the condition that the shape, shaft end and installation dimensions remain unchanged. , The gear shaft is 42CrMo, the large gear is ZG35CrMo, the quenched and tempered hardness gear shaft is 291-323HB, and the large gear is 255-286HB. ZQA type reducer is mainly used in industries such as lifting, mining, general chemical, textile, light industry and so on.
