Problems solved by technology
The more common mechanical transmission methods are mainly metal belt continuously variable transmissions. This type of transmission adopts friction transmission mode, which has poor acceleration ability, easy to slip during rapid acceleration, cannot bear too much torque, and has limited transmission power.

The invention discloses a chain type stepless speed change mechanism. The transmission shape of chains is coherently changed by synchronously and reversely adjusting transmission cone disc groups of a power input part and a power output part, the continuity of transmission ratio change is ensured, and stepless speed change is realized. Chain type transmission is adopted, two chains are arranged to form two transmission chain combinations, power transmission is carried out under cooperation of a bevel gear differential device between the two transmission chain combinations, and the situation that when a single chain is used, the chain and chain wheel teeth cannot be accurately engaged due to free rotation of a planetary chain wheel can be effectively avoided. Meanwhile, when the transmission conical disc groups rotate and after the variable-diameter adjustment, the chain wheel and the chains can be accurately engaged, so that the continuity and the stability of power transmission are ensured. Due to the fact that chain engagement transmission is achieved, compared with the prior art, the chain type stepless speed change mechanism effectively overcomes the defects that a friction transmission mode is poor in acceleration capacity, prone to slipping during rapid acceleration and incapable of bearing too large torque, and the transmission power is improved.
Description
Technical field [0001] The present invention relates to a mechanical transmission mechanism, and more particularly to a chain-constant speed mechanism. Background technique [0002] The shifting mechanism is a transmission for changing the speed and torque, widely used in various mechanical transmission systems, such as mechanical equipment such as belt conveyors and vehicles such as transit mechanisms. Currently, it is primarily classified into type variable speed, non-sedimentary speed and integrated speed. Among them, the non-sedentary transmission mechanism is a variable speed system that can continuously obtain any transmission ratio in the shift range. The best matching of the drive train and engine conditions can be obtained by stepless variable speed. In order to achieve stepless variable speed, three ways of liquid transmission, power transmission, and mechanical transmission can be used in transmission. More common in mechanical transmission mode mainly metal belt-type ...
