CHC type gear linked gear reducer with small tooth difference is a new generation of deceleration transmission device independently designed and developed by our company (the product has obtained two national patents, patent No.: ZL 952 01831.4, ZL 200720084515. X). The reducer has obtained the product type test certificate issued by the national quality supervision and inspection center of lifting and transportation machinery.
CHC type gear reducer with small tooth difference is composed of two parts: the high speed light load part of the involute cylindrical gear transmission and the low speed heavy load part of the chain small tooth difference transmission. The power is input from the high-speed light load gear transmission system. Through the high-speed small gear split deceleration to the intermediate transition gear shaft, the torque is transmitted to the low-speed and heavy-duty part with a small tooth difference. The two eccentric supporting shafts of the ring gear plate input torque at the same time, driving the ring gear plate to make planar chain reciprocating motion. The meshing with the inner gear ring of the ring gear plate is that multiple teeth enter the meshing area at the same time Through the principle of less tooth difference transmission, the output external gear shaft transmits the torque to the working machinery, so as to realize the purpose of high speed light load to large speed ratio, low speed and heavy load.
Compared with the traditional reducer, CHC type gear ring reducer with small tooth difference has large transmission ratio (maximum speed ratio up to 20000), large bearing capacity (maximum transmission torque up to 1000KN. M), strong overload resistance and large load ratio (load ratio refers to the ratio of bearing capacity to self weight of reducer, It has the advantages of compact structure, light weight, high transmission efficiency, long service life, convenient maintenance and high performance price ratio.
At present, the reducer has formed a series of products. It can replace planetary gear reducer, cycloid pin gear reducer, cylindrical gear reducer, worm gear reducer and three ring reducer. It can be widely used in water conservancy and hydropower, lifting and transportation, metallurgy, mining, construction machinery, petroleum, chemical, national defense engineering, port and ship, light industry and other major industrial fields.
