- Introduction of F series reducer
F series reducer, combined with international technical requirements, has high technical content, saves space, is reliable and durable, and has high overload capacity. The power of the reducer can be 90KW, the energy consumption high-speed mixer is low, the performance is superior, the speed reduction effect is up to 95%, the vibration is low, and the energy is high.
F series parallel shaft hardened gearbox adopts high-quality forged steel material, steel cast iron box body, the surface of the gear is subjected to high-frequency heat treatment, and precision machining ensures the parallelism of the shaft and the accuracy of positioning. All of these constitute the gear unit of the gear transmission assembly. The various types of electrodes form an electrode integration, which fully guarantees the quality of the product.
- Hardened surface reducer
Hardened gear reducers mainly include parallel shaft series and vertical shaft series. Parallel shaft hardened gearbox are produced according to national standards. The products have been optimized and have advanced international standards in the 1980s. It mainly includes ZDY (single-stage), ZLY (two-level), ZSY (three-level) and ZFY (four-level) four-column cancer series. Vertical shaft reducers are produced to national standards. The transmission device is arranged in the vertical direction of the input shaft and the output shaft, and mainly includes three series of DBY, dcy and DFY.
The main parameters such as center distance and nominal transmission ratio are optimized, and the main parts and parts are interchangeable. The gears are made of high-quality alloy steel by carburizing and quenching. The hardness of the tooth softener is 54-62HRC. The utility model has the advantages of small volume, light weight, high precision, large carrying capacity, high efficiency, long service life, high reliability, stable transmission and low noise.
Generally used oil pool lubrication, natural cooling, when the thermal power can not be met, can use circulating oil lubrication or fan cooling, coil cooling.
The nominal input power of the Parallel shaft hardened gearbox is stable according to the load. The working time per day is less than or equal to 10h, and the starting time is no more than 5 times per hour. The allowable starting torque is twice the working torque, one-way operation, single-pair gear The contact strength safety factor is about 1, and the failure probability is less than or equal to 1%.
When the Parallel shaft hardened gearbox is running in both directions, the PA should be multiplied by the coefficient of O.8-1.O according to the top ten brands of paint. When the reverse load is large, the commutation is frequent, and the reliability coefficient KR is low, the coefficient is compared. Small value. On the contrary, take a larger value. The permissible thermal power Pr of the parallel shaft series gearbox is suitable for ambient temperature 20 ° C, 100% continuous operation and power utilization per hour, and must be corrected if conditions are different.
- Overview of hardened surfaces
The bearing capacity of the gear tooth surface should be related to the hardness of the tooth surface. The higher the hardness, the higher the bearing capacity. According to the hardness of the tooth surface, people usually divide the gear transmission into two types, namely hard tooth surface gear transmission and soft tooth surface gear transmission. Usually, the tooth surface hardness of a pair of meshing gears is greater than 350HBS, which is called a hard tooth surface gear, otherwise it is called a soft tooth surface gear.
