Abstract
A speed-adjustable gearbox device is a slab rolling matching device for thick slabs in a rough production line and a fine production line in the steel smelting industry. The gear box body is internally provided with high-speed shaft teeth and a low-speed shaft, the high-speed shaft teeth are provided with a high-speed shaft gear, the low-speed shaft is provided with a low-speed gear I and a low-speed gear II, and the low-speed shaft is sleeved with an outer borrowing wheel, an inner borrowing wheel and a special shifting fork for a shifting gear. Because set up high-speed shaft tooth, low-speed axle in the gear box, drive and borrow the wheel through adjusting the special shift fork of gear shifting gear when needing the speed governing, start high-speed shaft tooth or low-speed axle operation, obtain different rotational speeds for single gear box possesses two kinds of speed ratios of height, and the adjustable change of drive ratio can satisfy different rolling slab thickness requirements, need not to change the gear box, can prolong the life of the relevant equipment of rolling copper wire, improvement production efficiency.
Description
Technical field
The utility model relates to a kind of smelting iron and steel industry that is used for, the supporting gear box device of using of thick, smart production line slab rolling of heavy slab.
Background technology
In the existing domestic and international smelting iron and steel industry, thick, finishing mill transmission system supporting uni-drive gear box unit speed reducing ratio immobilize, can not speed governing because rolled slab thickness is several kinds of fixing.When market has different order to require to rolling thickness of slab, just need to change the corresponding gear-box of answering speed ratio of transmission, cost of idleness and shutdown replacing time influence the performance of enterprises.Do not utilize former machine speed will reduce greatly than its production efficiency of rolled slab if do not change, influence the production output of steel mill, relevant device does not match the service life of meeting reduction equipment in addition.Order the gear-box complete machine spare unit of different speed ratios.
Summary of the invention
In order to solve above-mentioned existing problems, the utility model provides a kind of transmission gear means of governing speed as required, and this device is applicable to the adjustable speed travelling gear case apparatus of the thickness of producing different rolled plates.
The purpose of the utility model realizes through following technical scheme: adjustable speed travelling gear case apparatus; It is characterized in that: in gear housing, be provided with high speed shaft tooth, slow-speed shaft; On the high speed shaft tooth, be provided with the high speed shaft gear; On slow-speed shaft, be provided with low speed power shift gear I, low speed power shift gear II, suit wheel for public use, interior wheel and the special-purpose shift fork of power shift gear borrowed on slow-speed shaft.
The beneficial effect of the utility model: because high speed shaft tooth, slow-speed shaft are set in gear-box; Drive by means of wheel through the special-purpose shift fork of adjustment power shift gear when needing speed governing, start the running of high speed shaft tooth or slow-speed shaft, obtain different rotating speed; Make the separate unit gear-box possess two kinds of speed ratios of height; The gearratio adjustable speed changes and can satisfy different rolled slab thickness requirements, need not to change gear-box, can prolong the steel rolling line relevant device service life, enhance productivity.
