Description
Technical field
The utility model relates to a kind of tooth through-drive formula main axle structure, particularly a kind of gear main axle structure that is used for horizontal Machining centers.
Background technology
The existing main shaft that is used for machining center is mainly electric main shaft and two kinds of forms of gear main shaft, and electric main shaft can be realized high rotating speed, and the gear main shaft can be realized high-power, high pulling torque.The above gear speed of mainshaft of existing moment of torsion 2000 (Nm) 4500 (rev/min) below, limited the scope of application as the machining center of general process equipment, production efficiency is low.Reason is the gear drive scheme that high pulling torque (more than the 2000Nm) gear main shaft generally adopts the big retarding ratio, and main shaft appearance and size is big, weight is heavier, and this makes the feed speed of lathe lower; The gear main shaft bearing adopts grease lubrication in addition, also limited main shaft gyration speed, the main shaft bearing diameter adopts grease lubrication main shaft maximum (top) speed below 4500 rev/mins when 110mm at present, so existing gear main axle structure inefficiency, the scope of application is restricted.
Summary of the invention
The purpose of this utility model provides a kind of high efficiency, the gear main axle structure that is used for horizontal Machining centers that the scope of application is wide, overcomes the deficiencies in the prior art.
The gear main axle structure that is used for horizontal Machining centers of the present utility model, comprise main shaft casing and the driving shaft that be arranged in parallel that is bearing on the main shaft casing, jackshaft, main shaft, be fixed with driving shaft first gear and driving shaft second gear on the described driving shaft, be fixed with main shaft first gear and main shaft second gear on the described main shaft, described jackshaft is provided with can be in axial sliding and jackshaft first gear that is connected as a single entity along jackshaft, jackshaft second gear and jackshaft the 3rd tooth axle, described driving shaft first gear can with jackshaft first gears engaged, jackshaft second gear can with main shaft first gear and driving shaft second gears engaged, jackshaft the 3rd gear can with main shaft second gears engaged, described jackshaft first gear, jackshaft second gear and jackshaft the 3rd tooth axle are accepted cylinder driving shift fork by declutch shift shaft.
The gear main axle structure that is used for horizontal Machining centers of the present utility model, the lubricating system of the bearing of wherein said supporting spindle is an oil-air lubrication.
The utility model compared with prior art has following advantage: maximum speed of spindle increases, high efficiency, the scope of application is extensive, and range of spindle speeds is between 35～6000 rev/mins, the main shaft peak torque can reach 2045Nm, has farthest reduced the appearance and size and the weight of main axle structure.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in the figure: 4 is driving shaft, and 8 is jackshaft, and 14 is main shaft, all is bearing on the main shaft casing by bearing, and above-mentioned three are arranged in parallel.The left end head of driving shaft 4 joins by shaft coupling 2 and motor 1.
Key is connected with driving shaft first gear 3 on driving shaft 4, is processed with driving shaft second gear 10 on driving shaft 4;
Key is connected with main shaft first gear 11 and main shaft second gear 12 on main shaft 14;
Being connected with by the spline mode on jackshaft 8 can axially movable jackshaft the 3rd gear 7, the right-hand member of jackshaft the 3rd gear 7 is a parts of tooth, the left part of jackshaft the 3rd gear 7 outside key successively is connected with jackshaft first gear 5 and jackshaft second gear 6, makes be fixed as one structure and can endwisely slipping along jackshaft 8 of jackshaft first gear 5, jackshaft second gear 6 and jackshaft the 3rd gear 7.The left end of breast wheel the 3rd gear 7 is connected with shift fork 9 by shift fork bearing 13, and shift fork 9 is three cylinder drivings.
Driving shaft first gear 3 can mesh with jackshaft first gear 5, and jackshaft second gear 6 can mesh with main shaft first gear 11 and driving shaft second gear 10, and jackshaft the 3rd gear 7 can mesh with main shaft second gear 12.
The bearing of supporting spindle 14 comprises the 5th bearing 19 that is positioned at left part, is positioned at clutch shaft bearing 15, second bearing 16, the 3rd bearing 17 of right part successively, the lubricating system of the 4th bearing 18 is an oil-air lubrication, promptly be connected on the preceding support set 22 of main shaft on the main shaft casing and be processed with preceding oil-air lubrication passage 20, be connected and be processed with back oil-air lubrication passage 21 behind the main shaft on the main shaft casing on the support set 23, preceding oil-air lubrication passage 20, back oil-air lubrication passage 21 communicate with corresponding bearing and join with the fuel feeding device of air, form bearing lubrication system.
Promote shift fork 9 actions by three cylinders, when making jackshaft first gear 5, jackshaft second gear 6 and jackshaft the 3rd gear 7 be in leftmost bit, driving shaft first gear 3 is meshed with jackshaft first gear 5, and jackshaft second gear 6 is meshed with main shaft first gear 11, forms top gear; When being in rightmost position as jackshaft first gear 5, jackshaft second gear 6 and jackshaft the 3rd gear 7, driving shaft second gear 10 and 6 engagements of jackshaft second gear, jackshaft the 3rd gear 7 main shafts second gear 12 is meshed, and forms low or first gear; When being in meta as jackshaft first gear 5, jackshaft second gear 6 and jackshaft the 3rd gear 7, driving shaft second gear 10 and 6 engagements of jackshaft second gear, jackshaft second gear 6 is meshed with main shaft first gear 11 simultaneously, forms mid ranger; Above-mentioned three positions have formed three kinds of main shaft output revolutions, promptly high, medium and low three revolutions.
