Abstract
The invention relates to a main shaft device for a roller polisher. A taper sleeve of the main shaft (6), a spline shaft (42) and the main shaft (51) are connected through a conical surface of 7:24. A left stay bolt (7) and a right stay bolt (31) are connected with the main shaft (51) respectively; a belt pulley combining piece (36) is arranged on a suspension seat (25) through a deep groove ball bearing (27); the suspension seat (25) is fixed with a main shaft frame (55); the belt pulley combining piece (36) is connected with an internal spline (34) through a first end-face key (30) and a screw (35); and the internal spline (34) is connected with the spline shaft (42). The main shaft device for the roller polisher has a simple structure. Due to the adoption of the main shaft in a 7:24 conical surface connection form, the main shaft is centered and arranged through conical surface combination and screw tensioning; the main shaft-borne radial load is reduced by unloading the belt pulley; and the rotating precision and rigidity of the main shaft are improved. Therefore, the polishing efficiency and quality of roller workpieces are improved.
Description
Technical field
The invention belongs to parts of polishing plant machinery, be specifically related to a kind of main shaft device for roller polisher.
Background technology
Roller is the special part product and the spare part of textile machine spinning frame, for spinning enterprise, belong to expendable parts, the huge market demand, it also is the support product of textile machine manufacturing enterprise profitability, day by day but market situation with keen competition proposes higher requirement to the surface of roller quality in recent years,, gloss appearance uniformity, the product that jerk value is little, the soft and moist property of feel is good could guarantee the quality of resultant yarn better, become the demand of spinning enterprise acquisition of technology progress.
At present, all kinds of polishing machines of supplying on the polishing Equipment Market, certain specialty characteristics is mostly arranged, be adapted to different product product and industry, be broadly divided into forms such as general polishing machine, through type continuous polisher, multistation polishing unit, but these polishing machines all show in various degree defective for the glossing of a large amount of part rollers, can not solve the polishing problem of toothed surfaces well, even tooth top chamfering and efficiency.
Summary of the invention
Technical problem to be solved by this invention provides a kind of main shaft device for roller polisher, adopt the main shaft of 7: 24 conical surface types of attachment, can make the main shaft installation of accurately feeling relieved by conical surface combination and stretching screw, utilize the off-load belt pulley to reduce main shaft and bear radial load, improve main axis rotation precision and rigidity, thereby improved the polishing efficiency and the quality of roller workpiece.
Technical scheme of the present invention: a kind of main shaft device for roller polisher, it mainly comprises main shaft tapered sleeve, left lever bolt, right stay-bolt, hanging seat, deep groove ball bearing, straight end-face key, internal spline, screw, belt pulley conjunction, splined shaft, main shaft and main shaft frame, the conical surface that adopted 7: 24 between main shaft tapered sleeve, splined shaft and the main shaft is connected, and left lever bolt 7 is connected with main shaft respectively with right stay-bolt; The belt pulley conjunction is arranged on the hanging seat by deep groove ball bearing, and hanging seat and main shaft frame are fixed, and the belt pulley conjunction is connected by first straight end-face key and screw with internal spline, and internal spline is connected with splined shaft.
The present invention compared with prior art has following beneficial effect: 1, main shaft drives end of the present invention adopts off-load toothed belt wheel and 7: 24 conical surface types of attachment, bears by single-row angular contact ball bearing and radially reaches axial load; The other end adopts 7: 24 conical surface types of attachment to form the fixed bearing end, does not bear axial load, has improved main axis rotation precision and rigidity; 2, simple in structure, make the main shaft installation of accurately feeling relieved by conical surface combination and stretching screw, machine works is respond well, and noise significantly reduces, and the main shaft stable working has improved the polishing efficiency and the quality of workpiece; 3, overcome main shaft and axially traversed the influence of the alternation radial load that produces when cam or connecting rod drive shaft are traversed at a high speed in the rotation by splined shaft.
Description of drawings
Fig. 1 is a front view of the present invention.
The specific embodiment
A kind of main shaft device for roller polisher, it mainly comprises main shaft tapered sleeve 6, left lever bolt 7, right stay-bolt 31, hanging seat 25, deep groove ball bearing 27, straight end-face key 30, internal spline 34, screw 35, belt pulley conjunction 36, splined shaft 42, main shaft 51 and main shaft frame 55, the conical surface that adopted 7: 24 between main shaft tapered sleeve 6, splined shaft 42 and the main shaft 51 is connected, and left lever bolt 7 is connected with main shaft 51 respectively with right stay-bolt 31; Belt pulley conjunction 36 is arranged on the hanging seat 25 by deep groove ball bearing 27, and hanging seat 25 is fixing with main shaft frame 55, and belt pulley conjunction 36 is connected by first straight end-face key 30 and screw 35 with internal spline 34, and internal spline 34 is connected with splined shaft 42.
As shown in Figure 1, right stay-bolt 31 tension splined shafts 42 and main shaft 51, left lever bolt 7 tension main shaft tapered sleeves 6 and main shaft 51; Splined shaft 42 is fixed on the main shaft frame 55 by single-row angular contact ball bearing 39, bears main radial load and axial load, and main shaft tapered sleeve 6 is fixed on the main shaft frame 55 by deep groove ball bearing 3 and bearing the first from left end cap 1, bears radial load.Belt pulley conjunction 36 is supported on the hanging seat 25 fixing with main shaft frame 55 by deep groove ball bearing 27, form the off-load belt transmissioning mode.Motor power is stirred main shaft 51 rotations by belt pulley conjunction 36, straight end-face key 30, internal spline 34, splined shaft 42, second straight end-face key 43.Common first flat key 45, second flat key 48 that are installed on the main shaft 51 drive left and right spacer 44,49 of main shaft and cloth wheel back-up ring 47 and clamping screw 46 and rotate together, thickness by the right spacer 44 of increase and decrease main shaft, left spacer 49, regulate the center of cloth wheel, and lock the positions of polishing wheel on main shaft 51 with round nut 50.Sealing ring 26 embeds belt pulley conjunction 36 and forms the contact sealing with hanging seat 25, protection deep groove ball bearing 27; Right seal cover 20 and the right bearing end cap 40 clampings second wool dust ring 21 contact sealing with splined shaft 42 formation, protect single-row angular contact ball bearing 39; The rotation of case 10 protection left lever bolts 7 heads, a left side first seal cover 14 and the left clutch shaft bearing end cap 1 clamping first wool dust ring 5, contact sealing with the formation of main shaft tapered sleeve 6 left ends, a left side second seal cover 16 and left second bearing (ball) cover, 53 clampings the 3rd wool dust ring 52, contact sealing with the formation of main shaft tapered sleeve 6 right-hand members, protect deep groove ball bearing 3 jointly.Bearing all adopts grease lubrication.Case 10 is removed, screwed off left lever bolt 7, on main shaft frame 55, integral body such as main shaft tapered sleeve 6 and left clutch shaft bearing end cap 1 are ejected, screw off right stay-bolt 31 then main shaft 51 to be pulled down with screw 15 tops; The order that main shaft 51 is installed is then opposite.During the mounting or dismounting polishing wheel, main shaft 51 is vertically erected, the right-hand member flange face is attached on the frock taper hole end face, unclamp nut 17, pull down the left side cloth wheel back-up ring 47 and first packing ring 18, second packing ring 19, promptly can make things convenient for the mounting or dismounting of polishing wheel.
