Description
Technical field
The utility model belongs to a kind of turbine, relates to a kind of planetary long-life gear-hobbing machine.
Background technology
Gear-hobbing machine is a legacy equipment of making gear, uses extensively.The gear blank is installed on the gear-hobbing machine to be processed, as shown in Figure 1, the tradition gear-hobbing machine comprises rotary table and the upright slide rail that is installed on the base, the workpiece detent mechanism is installed on the described rotary table, the work arbor of this workpiece detent mechanism is fixed on down the upper end of round platform, this work arbor straight up, the top of work arbor is smooth cylinder, the bottom has screw thread, and be set with union (screwed)bonnet (UB and nut, work arbor and following round platform are used for Positioning Gear blank center, and nut and union (screwed)bonnet (UB are pressed on the gear blank on the work arbor.
Simultaneously, suit sliding platform on upright slide rail again, install on the sliding platform awl point downward press down circular cone, sliding platform drives and presses down circular cone and push down work arbor downwards.
When rotary table is made horizontal time rotational, nut and union (screwed)bonnet (UB have guaranteed that the gear blank can rotate synchronously with rotary table, press down bigger axial compressive force of circular cone generation simultaneously and press to work arbor, keep the stability and the rigidity of work arbor, guaranteed whole rotary table and the steady rotation of gear blank.
But its shortcoming is, want a bigger axial compressive force owing to press down the circular cone generation, this axial compressive force is delivered to rotary table downwards, cause rotary table under heavy load, to be worked for a long time, cause rotary table bearing-surface wearing and tearing aggravation, the gap increases, and influences equipment precision at last and reduces the lost of life of gear-hobbing machine.
And workpiece is fixed by the top connector that adds, because axiality control aspect has than large deviation, influences the quality of gear hobbing; Top axle journal position radial dimension is little, so tail spindle neck position rigidity is poor, yielding, and adds the easy workpiece skew longitudinal center line that takes place in man-hour, is difficult to satisfy the requirement of machining accuracy.
The utility model content
The purpose of this utility model provides a kind of long-life gear-hobbing machine, can eliminate axial compressive force straight down, avoids rotary table and base excessive friction, the service life of significantly improving rotary table.
For achieving the above object, a kind of long-life gear-hobbing machine described in the utility model, comprise the rotary table and the upright slide rail that are installed on the base, the workpiece detent mechanism is installed on the described rotary table, the work arbor of this workpiece detent mechanism straight up, be set with sliding platform on the described upright slide rail, its key is: on the described sliding platform sliding bearing is installed, the interior ring through hole of this sliding bearing is over against described work arbor, and the inner ring of this sliding bearing and described work arbor cross section match.
After sliding bearing moves down into the top of work arbor with sliding platform, the sliding bearing kink is lived work arbor, and no matter how work arbor rotates, and all is subjected to the constraint of sliding bearing, maintain the stability of work arbor, guaranteed whole rotary table and the steady rotation of gear blank.Simultaneously, eliminate axial compressive force, avoided rotary table and base excessive friction, the service life of significantly improving rotary table.
Owing to eliminated downforce, also just cancelled the hydraulic system of existing equipment, significantly reduced the manufacturing and the maintenance cost of gear-hobbing machine.
Lubricating cup also is installed on the described sliding platform, and the oil seepage port of this lubricating cup is towards described sliding bearing.
The lubricating cup oil impregnate has improved the lubricant effect of sliding bearing.Eliminate the friction between sliding bearing and the work arbor.
The lower end of described rotary table is connected the top of power transmission shaft, the rotation of power transmission shaft driven rotary workbench level.
Power transmission shaft can be by driven by motor.
Described workpiece detent mechanism comprises round platform down, and this described work arbor is fixed on the upper end of this time round platform, and the top of this work arbor is smooth cylinder, and the bottom has screw thread, and is set with union (screwed)bonnet (UB and nut.
The circumferencial direction of following round platform is provided with the key axle, when the thrust of union (screwed)bonnet (UB and nut is not enough, can fix the gear blank of processing by key.
Remarkable result of the present utility model is: a kind of long-life gear-hobbing machine is provided, has eliminated axial compressive force straight down, avoided rotary table and base excessive friction, the service life of significantly improving rotary table.Simultaneously,, also just cancelled the hydraulic system of existing equipment, significantly reduced the manufacturing and the maintenance cost of gear-hobbing machine owing to eliminated downforce.
