Is the interference fit or interference or transition, there is interference in this way of cooperation? What do you mean? Ask someone to explain it!
The gear on the shaft must transmit torque, so the shaft must be connected with the gear.The big gear adopts the key cooperation, the small and medium-sized gear adopts the interference fit, the tightening sleeve, etc. the small gear and the shaft are made into an integral whole.
In actual assembly, only the 2 combinations of clearance and interference are easy to understand. The transition fit is the possibility of both clearance fit and interference fit. Only after the parts are machined, the mating form can be decided at the time of assembly. The transition fit can be properly chosen, such as the transition coordination with larger gap coordination, or the transition fit with larger interference fit
In general, the load is small and smooth, and the clearance fit can be used, H7/h6. Large load and impact, use transition fit, H7/k6; H7/m6. The above 2 are the common form of coordination. If it is heavy load or severe shock, we should consider the interference fit.
The fixed gear on the shaft, with the shaft in the form of depending on the specific situation is different.To consider the use of circumstances, such as transmission power size, load stability, impact and so on. Also consider the manufacturability of the assembly
