Abstract
The utility model discloses an indexing mechanism for a heavy-duty spiral bevel gear shaving machine, which belongs to the field of spiral bevel gear shaving machines, and comprises a worm gear which is fixed on a workpiece main shaft, the worm gear is meshed with a worm, one end of the worm is connected with a motor, the workpiece main shaft is fixed with a damping wheel, and at least a damping block is arranged between the damping wheel and a workpiece box. In the indexing mechanism for the heavy-duty spiral bevel gear shaving machine, the damping wheel is fixed on the workpiece main shaft, the damping block is arranged between the damping wheel and the workpiece box, the operation of workpiece is steadier through the mutual action of the damping wheel and the damping block, the indexing is more accurate, thereby increasing the process precision of gears.
Description
Technical field
The utility model belongs to spiral bevel gear tooth-shaving machine field, is specifically related to a kind of indexing mechanism.
Background technology
Gear Production is occupied critical role in modernized machinery manufacturing industry, along with China's development of economic construction, production of China bevel gear and demand are also increasing rapidly.Teeth directional, profile of tooth, the tooth pitch equal error that will guarantee gear in the Gear Processing process require within the specific limits, just can guarantee processed tooth transmission accuracy height.In the Gear Processing process, lathe work spindle precision is low, the cage chair worm screw is inhomogeneous etc. for pitch error, overproof common the having of reason.Wherein, the work spindle precision is low is the one of the main reasons that causes that the backlash variable quantity is overproof.In the prior art, work spindle is set in the workpiece box, fixation workpiece chuck on the work spindle of the outer corresponding side of workpiece box, fixedly dividing worm wheel, worm gear and the worm engaging of the work spindle other end that workpiece box is outer with cutterhead.This workpiece box only is fit to the less gear of processing dimension, and when processing the gear of big specification, when surpassing 1600mm such as gear diameter, because this gear quality is big, inertia is big, can influence the accuracy of gear compound graduation, the machining accuracy of corresponding influence wheel.Along with the development of technology, more and more to the quantity required of large-scale high-precision gear, quality requirement is also more and more higher, and workpiece box indexing mechanism precision has been hanged down one of key factor into restriction large gear quality and quantity.
The utility model content
The technical problems to be solved in the utility model is that existing workpiece box indexing mechanism precision is low, provides a kind of precision the high indexing mechanism that is used for heavy spiral bevel gear tooth-shaving machine.
The technical solution of the utility model realizes with following method:
A kind of indexing mechanism that is used for heavy spiral bevel gear tooth-shaving machine comprises the worm gear that is fixed on the work spindle, worm gear and worm engaging, and worm screw one end connects motor, and fixing damping wheel on the work spindle is provided with at least one damping block between damping wheel and the workpiece box.
Described damping block is three, is separately positioned on the top, damping wheel outer ring and the left and right sides.
Being centered close on the same circumference of described three damping blocks.
In the utility model, fixing damping wheel on work spindle is provided with damping block between damping wheel and the workpiece box, by the interaction between damping wheel and the damping block, makes the operation of workpiece more steady, and calibration is more accurate, thereby improves the precision of Gear Processing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to cross-sectional schematic.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises the worm gear 1 that is fixed on the work spindle 10, worm gear 1 and worm screw 4 engagements, worm screw 4 one ends connect motor, fixing damping wheel 9 on the work spindle 10, be provided with between damping wheel 9 and the workpiece box in damping block 11. the utility model, adopt the high accuracy worm gear as indexing mechanism. worm screw 4 of processing is as 1 pair of parent that grinds of machining worm wheel earlier, by to grinding contact area being reached more than 75% after the worm gear gear hobbing, then to be that parent comes machining worm 4 that contact area is reached more than 75% to the worm gear 1 that ground, advanced the worm gear of grinding as the workpiece indexing mechanism
Be provided with thrust bearing 5 and cylinder roller bearing 2 between worm screw 4 and the worm gear case 3, worm screw 4 one end adpting flanges 6, flange 6 connection reducers 7, decelerator 7 connects motor 8.During work, motor 8 drives worm screw 4 and rotates, worm screw 4 and worm gear 1 engagement, and worm gear 1 drives work spindle and rotates.The accurate engagement of worm gear 1 and worm screw 4 has guaranteed that the processed gear position of work spindle end is accurate, and tooth pitch is accurate.Work spindle 10 is provided with damping wheel 9, and damping wheel 9 is provided with damping block 11, by the interaction between damping wheel 9 and the damping block 11, makes the operation of workpiece more steady, and calibration is more accurate.The effect that described damping wheel 9, damping block 11 play is equivalent to the effect of brake in the bicycle: be equivalent to brake locking but not locked state.Frictional force between dependence damping wheel 9, the damping block 11 has been offset the inertia force of workpiece and dividing worm wheel, makes calibration more accurate.
Described damping block 11 is three, is separately positioned on the damping wheel top, 9 outer ring and the left and right sides.Being centered close on the same circumference of described three damping blocks 11.Other is with embodiment 1.
