Is cycloid pinwheel reducer explosion-proof?
Explosion proof of cycloid pin gear reducer: advantages and disadvantages of cycloid pin gear reducer and planetary gear reducer?
The main feature of worm gear reducer is that it has reverse self-locking function and can have large reduction ratio. The input shaft and output shaft are not on the same axis or plane. However, the general volume is large, the transmission efficiency is not high, and the accuracy is not high.
The harmonic drive of the harmonic reducer uses the controllable elastic deformation of the reducer elements of the flexible reducer to transmit motion and power. It has small volume and high precision, but the disadvantage is that the flexible wheel has limited service life, is not resistant to impact, and its rigidity is poor compared with the metal parts. The input speed cannot be too high.
Planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly expensive.
Gear reducer has the characteristics of small volume and large transmission torque. The gear reducer is designed and manufactured on the basis of module combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is graded carefully to meet different service conditions and realize mechatronics. Gear reducer has high transmission efficiency, low energy consumption and superior performance.
Cycloid pin gear reducer is a transmission model based on the principle of cycloid pin tooth meshing planetary transmission. It is an ideal transmission device. It has many advantages, has a wide range of uses, and can run forward and backward
Explosion proof of cycloidal pinwheel reducer: what is the difference between bwes and BWD of cycloidal pinwheel reducer
These two cycloidal pinwheel reducers are two types of reducers, taking the (B Series) model as an example:
Bwd1 (Shanghai standard reducer) is equivalent to B series reducer.
(standard reducer of Ministry of chemical industry) reducer equivalent to B series model.
For the model mentioned: bwd1 is also equivalent to, and also equivalent to bwd5.
All dimensions of the two reducers are different, including size, center height, anchor bolt hole, output shaft diameter, matched motor power, etc.
Bwes shall be a two-stage horizontal cycloidal pinwheel reducer, and BWD shall be a single horizontal cycloidal pinwheel reducer.
Cycloid pin gear reducer is a new transmission machine designed based on the principle of cycloid pin tooth meshing and planetary transmission with small tooth difference. It has been widely used in metallurgy and mining, petrochemical industry, construction, lifting and transportation, textile printing and dyeing, engineering machinery, food industry, etc
