Description
Technical field
The invention belongs to mechanical engineering technical field, disclose a kind of furnace top distributing gear, especially for the furnace top distributing gear of ironmaking.
Background technology
Top distributor of blast furnace is the nucleus equipment of ironmaking furnace roof.The distributor of present domestic use almost is overseas equipment, the especially large blast furnace of introducing.This distributor of domestic introduction is to adopt planet differential mechanism vertical direction to install, and concentric shafts output transmission reaches the transmission requirement; Its planet differential mechanism and gear, worm gear are vertically installed, the oiling system complexity; Its concentric output shafts structure is complicated, and the tubular shaft size is bigger, and sealing is difficult for; In order to satisfy the big speed ratio requirement that chute fascinates, the previous stage transmission of the center sun gear of its planet differential mechanism is the worm and gear transmission, and as the propulsion source that chute fascinates, transmission efficiency is lower; Its chute junction of fascinating adopts gear to add the transmission of big speed ratio worm and gear, and not only transmission efficiency is low, and transmitting ratio is less, make the swing bearing and the strength of gear of tilting mechanism bigger, cause swing bearing and gear to be had relatively high expectations, or adopt expensive introduction part, the involving great expense of swing bearing.
Summary of the invention
The purpose of this invention is to provide a kind of furnace top distributing gear, satisfy the needs of ironmaking roof material distributing.The present invention is that rotating machine and tilting motor are independent of respectively a cover box of tricks transmission, wherein, all gear system is adopted in box of tricks and previous stage transmission, the geartransmission of a pair of common transmitting ratio is adopted in the previous stage transmission of the center sun gear of box of tricks, adopts three-ring gear reducer during chute fascinates.This distributor can be realized the function that chute fascinates, chute rotates and chute not only rotates but also fascinates.
Purpose of the present invention realizes in the following way: this distributor is made up of rotating machine, tilting motor, step down gear, box of tricks, rotating mechanism, tilting mechanism, three-ring gear reducer and chute etc., rotating machine and tilting motor are independent of respectively a cover box of tricks transmission, start-stop by controls revolution motor and tilting motor, realize the synchronous and differential of rotating mechanism and tilting mechanism, reach the transmission requirement.Wherein, all gear system is adopted in box of tricks and previous stage transmission, has improved transmission efficiency; Utilized this box of tricks center sun to take turns to planet carrier characteristic than big speed ratio has been arranged, the previous stage transmission of the center sun gear of box of tricks adopts the geartransmission of a pair of common transmitting ratio to replace the worm and gear transmission, as rotating power source, can satisfy the requirement of rotation transmitting ratio; Because chute has adopted three-ring gear reducer in fascinating, directly pinion(gear) of engagement can satisfy the chute transmitting ratio requirement of fascinating as the chute source of fascinating on the box of tricks external toothing; Because the box of tricks previous stage does not adopt the worm and gear transmission, so these part component are arranged comparatively compactness; Box of tricks and prime gear level are installed, and each master wheel size is approaching, are convenient to lubricate by common horizontal step-down gear mode, improve lubricating efficiency; Rotating mechanism parallel with tilting mechanism input gear shaft (non-concentric) is installed, and is convenient to sealing; Utilized three-ring gear reducer to have than big speed ratio, big supporting capacity, compact construction and the high characteristics of efficient, adding the transmission of close steps worm and gear with big speed ratio three ring decelerations replaces original big speed ratio worm and gear to add the close steps geartransmission, because the efficient height of the efficiency ratio big speed ratio worm and gear of the worm and gear of close steps, therefore, not only improve transmission efficiency but also increased transmitting ratio, solved the swing bearing and the big problem of strength of gear of tilting mechanism.
Characteristics of the present invention are that it can satisfy the normal cloth of iron-smelting furnace, the cloth in the time of also satisfying special operation condition.Its compact construction, stable drive, reliable operation, the transmission efficiency height, Maintenance and Repair are simple, save construction cost and maintenance cost.Be the desirable and practical structure of present iron-smelting furnace cloth, can be used for various iron-smelting furnace engineering, perhaps the place of other bulk material distribution.
