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
The present invention relates to ship machinery manufacturing technology field, particularly a kind of speed-changing gear box for marine crane hoister winch and the large-scale winch of other boats and ships.
Background technology
When traditional hoisting crane was worked, lifting velocity required lower, can satisfy the lifting velocity requirement so corresponding hoister winch only need connect tradition ordinary gear change speed gear box commonly used.But the lifting velocity that marine crane requires is higher, therefore requires the rotating speed of winch also higher, and common single input gear gearbox designs is difficult to satisfy high-speed requirement, so need the new speed-changing gear box of design to satisfy the rate request of winch.
Most typical a kind of speed-changing gear box comprises single input shaft in traditional speed-changing gear box, planetary gear speed reducing mechanism, output shaft etc., the described single input shaft of input motor that is connected with is by the sun wheel input of planetary gear speed reducing mechanism, planetary gear set is exported this mode, utilizes three grades of identical planetary gear speed reducing mechanism cascades to reach certain output torque and output speed.This speed-changing gear box output torque is less, generally at 75000 Ns below the rice, even and input motor when being in maximum speed of revolution, its output speed neither be very high, the workload of whole speed-changing gear box is very large.Therefore, this speed-changing gear box can't satisfy marine crane hoister winch and the requirement of the large-scale winch of other boats and ships to output torque and output speed.
Summary of the invention
The object of the present invention is to provide a kind of speed-changing gear box that possesses simultaneously high output torque and high output speed.
In order to address the above problem, the technical scheme of this speed-changing gear box is: this speed-changing gear box includes input shaft, gear, planetary gear set, sun wheel, internally toothed annulus, output shaft etc.This speed-changing gear box has two input shafts, a miniature gears is installed on each described input shaft, each described miniature gears all meshes with same big gear wheel, described big gear wheel is connected with the sun wheel of primary planet pinion mechanism, the planetary gear set engagement of described sun wheel and primary planet pinion mechanism, described planetary gear set and an internally toothed annulus engagement, the pinion carrier of primary planet pinion mechanism is connected with the sun wheel of secondary planetary gear mechanism, the pinion carrier of secondary planetary gear mechanism is fixed on pedestal, the sun wheel of described secondary planetary gear mechanism and the engagement of the planetary gear set of secondary planetary gear mechanism, the planetary gear set engagement of the second internal tooth of described internally toothed annulus and described secondary planetary gear mechanism is by described internally toothed annulus output torque.
Because adopt technique scheme, the present invention compared with prior art has following beneficial effect:
1. the present invention possesses high output torque and high output speed simultaneously, and the output torque of this speed-changing gear box can reach 10 tons more than the rice, and output speed is faster more than 20% than existing.
2. volume of the present invention is relatively small and exquisite, and structure is compact.
