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 for the speed-changing gear box of marine crane hoister winch with the large-scale winch of other boats and ships.
Background technology
When traditional hoisting crane works, lifting velocity requires lower, therefore the ordinary gear change speed gear box that corresponding hoister winch only need connect tradition conventional can meet lifting velocity requirement.But the lifting velocity that marine crane requires is higher, therefore requires that the rotating speed of winch is also higher, common single input gear change box structure is difficult to the requirement meeting high speed, so need to design new speed-changing gear box to meet the rate request of winch.
In traditional speed-changing gear box, most typical a kind of speed-changing gear box comprises single input shaft, planetary gear speed reducing mechanism, output shaft etc., the described single input shaft being connected with input motor is inputted by the sun wheel of planetary gear speed reducing mechanism, planetary gear set exports 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 below 75000 Ns of rice, even and if input motor when being in maximum speed of revolution, its output speed neither be very high, and the workload of whole speed-changing gear box is very large.Therefore, this speed-changing gear box cannot meet the requirement to output torque and output speed of marine crane hoister winch and the large-scale winch of other boats and ships.
Summary of the invention
The object of the present invention is to provide a kind of speed-changing gear box simultaneously possessing high output torque and high output speed.
In order to solve the 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, input shaft described in each is provided with a miniature gears, each described miniature gears all engages with same big gear wheel, described big gear wheel is connected with the sun wheel of primary planet pinion mechanism, described sun wheel engages with the planetary gear set of primary planet pinion mechanism, described planetary gear set engages with an internally toothed annulus, 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 engages with the planetary gear set of secondary planetary gear mechanism, second internal tooth of described internally toothed annulus engages with the planetary gear set of described secondary planetary gear mechanism, by described internally toothed annulus Driving Torque.
Owing to adopting 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 more than 10 tons of rice, and output speed is than existing fast more than 20%.
2. volume of the present invention is relatively small and exquisite, and structure comparison is compact.
Accompanying drawing explanation
Fig. 1 is transmission schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
This speed-changing gear box shown in Fig. 1, includes input shaft, gear, planetary gear set, sun wheel, internally toothed annulus, output shaft etc.Its concrete structure is for being provided with two input shafts 1, each input shaft 1 is provided with a miniature gears 2, each miniature gears 2 all engages with same big gear wheel 10, big gear wheel 10 is connected with the sun wheel 8 of primary planet pinion mechanism, sun wheel 8 engages with the planetary gear set 7 of primary planet pinion mechanism, planetary gear set 7 engages with an internally toothed annulus 9, the pinion carrier 6 of primary planet pinion mechanism is connected with the sun wheel 4 of secondary planetary gear mechanism, the pinion carrier 3 of secondary planetary gear mechanism is fixed on pedestal, the sun wheel 4 of secondary planetary gear mechanism engages with the planetary gear set 5 of secondary planetary gear mechanism, second internal tooth of internally toothed annulus 9 engages with the planetary gear set 5 of secondary planetary gear mechanism, by internally toothed annulus 9 Driving Torque.
