Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] figure 1 The gear box shown includes an input shaft, gears, a planetary gear set, a sun gear, an inner ring gear, an output shaft, and the like. Its specific structure is that there are two input shafts 1, and each input shaft 1 is equipped with a pinion 2, and each pinion 2 is meshed with the same large gear 10, and the large gear 10 is connected to the sun of the first-stage planetary gear mechanism. The gear 8 is connected, the sun gear 8 meshes with the planetary gear set 7 of the first-stage planetary gear mechanism, the planetary gear set 7 meshes with an inner ring gear 9, and the planet carrier 6 of the first-stage planetary gear mechanism meshes with the sun gear of the second-stage planetary gear mechanism 4 connection, the planet carrier 3 of the two-stage planetary gear mechanism is fixed on the base, the sun gear 4 of the two-stage planetary gear mechan...

Abstract

The invention discloses a gear transmission case. The gear transmission case comprises input shafts, gears, a planetary gear set, sun gears, an inner gear ring, an output shaft and the like. The gear transmission case comprises two input shafts, a small gear is mounted on each input shaft, each small gear is meshed with a same large gear, the large gear is connected with the sun gear of a first-stage planetary gear mechanism, the sun gear is meshed with a planetary gear of the first-stage planetary gear mechanism, the planetary gear set is meshed with the inner gear ring, a planet carrier of the first-stage planetary gear mechanism is connected with the sun gear of a second-stage planetary gear mechanism, the plant carrier of the second-stage planetary gear mechanism is fixed on a base, the sun gear of the second-stage planetary gear mechanism is meshed with the planetary gear set of the second-stage planetary gear mechanism, second-link inner teeth of the inner gear ring are meshed with the planetary gear set of the second-stage planetary gear mechanism, and torque is output through the inner gear ring. Compared with the prior art, the gear transmission case disclosed by the invention can solve the problems of small output torque and low output rotational speed of the traditional ordinary gear transmission case.

Description

technical field [0001] The invention relates to the technical field of ship machinery manufacturing, in particular to a gear box for marine crane hoisting winches and other large ship winches. Background technique [0002] When the traditional crane is working, the lifting speed requirement is relatively low, so the corresponding lifting winch only needs to be connected to the traditional common gear box to meet the lifting speed requirement. However, the lifting speed required by marine cranes is high, so the speed of the winch is also required to be high. It is difficult for the ordinary single-input gear box structure to meet the high speed requirements, so a new gear box needs to be designed to meet the speed requirements of the winch . [0003] The most typical gear box in the traditional gear box includes a single input shaft, a planetary reduction mechanism, an output shaft, etc., the single input shaft connected to the input motor is input through the sun gear of t...
