The roller polishing machine main shaft device with simple structure adopts the main shaft with a connection mode of the 7:24 conical surface, enables the main shaft to be accurately centered and installed through conical surface combination and tightly pulling the screw nail, reduces bearing radial load of the main shaft by an unloading belt wheel and increases rotating accuracy and rigidity of the main shaft, thereby increasing polishing efficiency and quality of a roller workpiece.
Description
Technical field
The utility model belongs to parts of polishing plant machinery, is 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 in the utility model 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.
The technical solution of the utility model: 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 utility model compared with prior art has following beneficial effect: 1, the utility model main shaft drives end 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.
