Description
Technical field
This is bright relates to a kind of tooth through-drive formula main axle structure, particularly a kind of gear spindle structure for horizontal Machining centers.
Background technology
Existing main shaft 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 2000Nm) gear main shaft generally adopts the big retarding ratio, and main shaft appearance and size is large, 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 when 110mm, adopts grease lubrication main shaft maximum (top) speed below 4500 rev/mins at present, so existing gear spindle structure inefficiency, the scope of application is restricted.
Summary of the invention
This bright purpose is to provide a kind of high efficiency, the gear spindle structure that is used for horizontal Machining centers that the scope of application is wide, overcomes the deficiencies in the prior art.
the gear spindle structure that is used for horizontal Machining centers that this is bright, comprise main spindle box body and the driving shaft that be arranged in parallel that is bearing on main spindle box body, jackshaft, main shaft, be fixed with driving shaft the first gear and driving shaft the second gear on described driving shaft, be fixed with main shaft the first gear and main shaft the second gear on described main shaft, described jackshaft is provided with can be in axial sliding and jackshaft the first gear that is connected as a single entity along jackshaft, jackshaft the second gear and jackshaft the 3rd gear, described driving shaft the first gear can mesh with jackshaft the first gear, jackshaft the second gear can mesh with main shaft the first gear and driving shaft the second gear, jackshaft the 3rd gear can mesh with main shaft the second gear, described jackshaft the first gear, jackshaft the second gear and jackshaft the 3rd gear are accepted cylinder-pushed formula shift fork by declutch shift shaft.
The gear spindle structure that is used for horizontal Machining centers that this is bright, the lubricating system of the bearing of wherein said supporting spindle is oil-air lubrication.
Basis is bright compared with prior art to be had the following advantages: 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 appearance and size and the weight of main axle structure.
Description of drawings
Fig. 1 is the structural representation of this bright 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 main spindle box body by bearing, and above-mentioned three axles 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 the first gear 3 on driving shaft 4, is processed with driving shaft the second gear 10 on driving shaft 4;
Key is connected with main shaft the first gear 11 and main shaft the 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 parts of tooth, the left part of jackshaft the 3rd gear 7 outside key successively is connected with jackshaft the first gear 5 and jackshaft the second gear 6, makes be fixed as one structure and can endwisely slipping along jackshaft 8 of jackshaft the first gear 5, jackshaft the 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 the first gear 3 can mesh with jackshaft the first gear 5, and jackshaft the second gear 6 can mesh with main shaft the first gear 11 and driving shaft the second gear 10, and jackshaft the 3rd gear 7 can mesh with main shaft the second gear 12.
The bearing of supporting spindle 14 comprises that the lubricating system of the 5th bearing 19 that is positioned at left part, the clutch shaft bearing 15 that is positioned at successively right part, the second bearing 16, the 3rd bearing 17, the 4th bearing 18 is oil-air lubrication, namely be connected on the main shaft front support cover 22 on main spindle box body and be processed with front oil-air lubrication passage 20, be connected on the main shaft rear support cover 23 on main spindle box body and be processed with rear oil-air lubrication passage 21, front oil-air lubrication passage 20, rear oil-air lubrication passage 21 communicate and join with the fuel feeding device of air with corresponding bearing, form bearing lubrication system.
Promote shift fork 9 actions by three cylinders, when making jackshaft the first gear 5, jackshaft the second gear 6 and jackshaft the 3rd gear 7 be in leftmost bit, driving shaft the first gear 3 is meshed with jackshaft the first gear 5, and jackshaft the second gear 6 is meshed with main shaft the first gear 11, forms top gear; When being in rightmost position as jackshaft the first gear 5, jackshaft the second gear 6 and jackshaft the 3rd gear 7, driving shaft the second gear 10 and jackshaft the second gear 6 engagements, jackshaft the 3rd gear 7 main shaft the second gears 12 are meshed, and form low or first gear; When being in meta as jackshaft the first gear 5, jackshaft the second gear 6 and jackshaft the 3rd gear 7, driving shaft the second gear 10 and jackshaft the second gear 6 engagements, jackshaft the second gear 6 is meshed with main shaft the first gear 11 simultaneously, forms mid ranger; Above-mentioned three positions have formed three kinds of main shaft output revolutions, i.e. high, medium and low three revolutions.
