Problems solved by technology

In addition, because there is no clutch, the vehicle cannot be towed at high speed when it needs to be towed;
[0006] In hoisting machinery, because the hook has a certain weight, whether it is lifting heavy objects or not, the gear shifting of the hoisting mechanism is a load shifting, and the hook is not allowed to have any weight during the gear shifting process. The phenomenon of slipping, not to mention the phenomenon of out-of-gear during the working process, which makes it more difficult to realize the shifting of the mechanism

Abstract

The present invention provides a planetary transmission shifting mechanism capable of shifting gears, which includes a shifting device and a planetary transmission mechanism. The planetary transmission mechanism is provided with an input shaft and an output end. The planetary transmission shifting mechanism includes two or more The gears, the output ends of each gear are connected as a whole, and the input shaft input power can be either the output of the ring gear or the output of the planetary carrier. This planetary transmission shift mechanism is widely used in construction machinery, petroleum machinery, and chemical machinery. , construction machinery, mining machinery, ship machinery, etc., the planetary gear shifting mechanism uses a planetary mechanism to realize multi-gear gear shifting. Using a planetary transmission drive mechanism, etc., the shift mechanism has the advantages of convenient and reliable gear shifting, a wide range of transmission ratios, high load-bearing capacity, and the ability to achieve large speed ratio shifts.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a planetary gear shift reducer. Background technique [0002] Planetary transmission is widely used in construction machinery, construction machinery, ship machinery, petroleum machinery, chemical machinery and mining machinery and so on. The existing hoisting mechanism, traveling mechanism, power head, etc. have not realized multi-gear gear shifting, which affects work efficiency. [0003] For example, the planetary drive hoisting mechanism used in truck cranes has no gear shifting function and is still at the same speed. Therefore, the speed cannot be changed under the empty hook, when lifting or under light load, and when lifting, which affects the working efficiency of the hoisting mechanism. Accelerate the speed of lowering or lifting the hook within the controllable speed range, and the efficiency of the hoisting mechanism will be greatly improved when working with light loads and ...
