Abstract
The invention discloses a main-gear box which is applicable to the rotation of main workbenches of large vertical lathes with the height of 6.3-13 meters and the like.
Description
Technical field
Patent of the present invention is a Novel vertical lathe with two grades of gearboxes, is applicable to 20 meters main workbench transmissions that wait the large-sized multifunction vertical lathe of 6.3 meters-∮ of ∮.
Technical background
The gearbox that existing domestic large-scale vertical lathe uses is generally fourth gear.The four-speed gear shift box structure is complicated, and manufacturing cost is high, and when the vertical lathe cutting diameter increased, gear need be equipped with the transition case can satisfy the cutting requirement, has strengthened manufacturing cost, has added failure factor; The main transmission of two grades of gearboxes and motor are limit because of structure and placed the casing lower end, easily produce draining and maintenance difficulty, and be very inconvenient.In the case, I scientific research personnel of company organization tackles key problems, and adopts the CAD optimal design, combines the advantage of different gearbox designs, has created novel appearance design, transmission system simple in structure.Namely reduce cost, improved again the service life of lathe.Successfully solved the problems such as draining, maintenance difficulty, also reached the vary in diameter of large-scale vertical lathe main-gear box because of cutting workpiece, increased the problem of equipped transition mechanism, two grades of gearboxes reach the four-speed gear shift effect equally.
Summary of the invention
The novel large vertical lathe is comprised of direct current generator, I shaft gear axle, II axle, II shaft gear, III axle, III shaft gear, IV axle, IV shaft gear, shifting gear, V axle, V shaft gear, casing, bearing etc. with gearbox.
(1) reasonable in design, advanced person, very steady under the duty, can satisfy speed change again can heavy cut, is easy to assembling, maintenance.
(2) material selection is appropriate, selects Fine Steel Casting iron, adopts modified, Quenching Treatment, has namely reduced manufacturing cost, has improved service life again.Gear adopts hard flank of tooth roll flute gear, greatly reduces noise.
(3) main-gear box transmission table
Description of drawings
Fig. 1: the main-gear box structure chart, transmission principle is as follows:
Direct current generator drives I shaft gear axle by shaft coupling and rotates, I shaft gear axle drives the II axle by II axle lower gear and rotates, thereby the II axle cogs and drives the rotation of III axle lower gear drive III axle, two gears in III axle top drive respectively two gears of IV axle and rotate, shifting gear slides up and down respectively at lower gear on the IV axle by oil cylinder control and meshes to realize gearshift in the middle of the IV axle, IV axle shifting gear drives V axle lower gear and rotates, the rotation thereby drive V axle cogs, the V axle cogs and drives the rotation of vertical lathe base internal gear, thereby realizes that workbench rotates.
Fig. 2: main-gear box transmission table
Speed ratio: top gear is that 6.14-24.57 passes/divides
Low or first gear is that 0-6.18 passes/divides.
Claims (4)
1.6.3-13 meters vertical lathe workbenchs of rice rotate with main-gear box external form, inner structure form and speed ratio.
2. the main-gear box that requires according to right 1 is characterized in that:, parallel structure on main motor and the gearbox, and motor and gearbox are direct-connected.
3. the main-gear box that requires according to right 1 is characterized in that: the casing outward appearance.
