Description
Technical field
The present invention relates to Gear Processing field, be specially the processing of helical gear.
Background technology
It is good that helical gear has engagement property, the advantage that stable drive, noise are little.Further, its registration is large, reduces the load of often pair of gear, improves the bearing capacity of gear.And it is few not produce the minimum teeth number that root cuts.Because its field of conjugate action is by little,---greatly---little, steadily, impact little, noise is little in engagement; Therefore there is large bearing capacity, gear life and stationarity can be improved; And volume is little.Helical gear drive is meshed by two helical gears and forms.Purposes transmits the motion between the crossed axis of space two.But, making trouble of helical gear, and be difficult to the teeth groove accuracy of form and position ensureing processing.
In particular, in some embody rule fields, such as flexible material (as plastics) processing, traditional intermetallic composite coating mode reduces costs being difficult to meet and improving the requirement of process velocity and precision.
Summary of the invention
The object of the invention is the processing mode in order to provide a kind of helical gear, it has the high advantage of the single teeth groove precision that is succinct, processing of process equipment.Further, can meet in some flexible materials for the requirement that processing cost (especially tooling cost) reduces.
According to aspects of the present invention, a kind of by motor-driven helical gear organisation of working, for using when processing blank, it comprises: pedestal, rotatable inner thread piece, external thread piece and columned Workpiece carrier part, wherein, rotatable inner thread piece comprises cylindrical portion and lower chambers portion, described lower chambers portion by bearing arrangement and pedestal circumference can rotate and axial restraint be connected, external thread piece is cylindric, its outer circumference surface is provided with external screw thread to engage with the internal thread in described upper cylindrical portion, upside at pedestal in lower chambers portion is provided with drive motors, drive motors is connected with the lower end of the first axle, described first axle is provided with first gear and the first pinion from bottom to up successively regularly, the inside circumference face in described lower chambers portion is fixedly installed ring gear, first gear engages with described ring gear, described rotatable inner thread piece can be driven when drive motors is rotated to rotate relative to pedestal, the bottom end face left-hand portion place of described external thread piece is provided with the cylindric extension in a left side to downward-extension regularly, the top of the first axle is inserted in described cylindric extension, and can coordinate rotationally with described cylindric extension,
Described columned Workpiece carrier part all overlaps with the axial line of external thread piece and described upper cylindrical portion, its upper end is provided with blank clamping structure, middle part, lower end is provided with the middle circle column extension to downward-extension regularly, the bottom of described columned Workpiece carrier part is connected with external thread piece by lower bearing, top is connected with ring-type capping by upper bearing (metal), described ring-type capping and external thread piece are fixed, thus, described columned Workpiece carrier part can rotate relative to described external thread piece; Second axle is installed the middle part axial restraint of described pedestal, the lower end of described second axle is connected with described pedestal, top is inserted in described middle circle column extension, and the axial line of described second axle overlaps with the axial line of described columned Workpiece carrier part, described second axle all can coordinate rotationally with described pedestal and described middle circle column extension; The bottom of described second axle is provided with enlarged diameter portion, to increase the rigidity of described second axle; The position of described second axle above its enlarged diameter portion is installed with second largest gear and the second pinion from bottom to up successively, and second largest gear engages with the first pinion;
Described pedestal is provided with the 3rd axle on the right side of described second axle with going back axial restraint, the lower end of described 3rd axle is connected with described pedestal, top is inserted into the blind hole of the right side wall being arranged in described external thread piece, and described 3rd axle all can be coordinated rotationally with described pedestal and described blind hole; The bottom of described 3rd axle is also provided with enlarged diameter portion, to increase the rigidity of described 3rd axle; Described 3rd position of axle above its enlarged diameter portion is installed with the third-largest gear and third pinion from bottom to up successively, and the third-largest gear engages with the second pinion; Third pinion is cylindric; The outer circumference surface of described middle circle column extension is installed with the fourth-largest gear, and the fourth-largest gear engages with described third pinion;
Thus, it is non-rotatable under described external thread piece is located while described first axle and described 3rd axle, when described drive motors rotates, described upper cylindrical portion drives external thread piece to move up and down, thus drives described columned Workpiece carrier part and blank to move up and down relative to pedestal; Meanwhile, drive motors can also be rotated relative to pedestal by Workpiece carrier part columned described in described gear drive and blank; And then, under the shear action of cutter, spiral alveolar can be processed on blank; When described columned Workpiece carrier part and blank rise to extreme higher position, the top of described first axle with between the cylindric extension in a described left side, the top of described second axle with between described middle circle column extension, the top of described 3rd axle with all still keep between described blind hole coordinating rotationally, described the fourth-largest gear still keeps engaging with cylindric described third pinion.
Pass through such scheme, owing to have employed the transmission of the gears at different levels of the fixing number of teeth, when thread pitch is certain, can ensure that the proportionate relationship between rotational angular velocity and riser speed is constant, therefore, which ensure that the precision of slot form in processing spiral alveolar process; And by specific vibrational power flow, the rotation that can realize circumferential angular speed slows down as far as possible, namely relative to the linear velocity risen, rotary speed is as far as possible slow, thus meets the shape need of helical gear.Meanwhile, what utilize power transmission shaft to rotate external thread sleeve is fixing, therefore, it is possible to ensure that it is not followed inner thread sleeve and rotates; And the central axes of middle power transmission shaft and the miscellaneous part of rotation, which ensure that the rotation of power transmission shaft can have nothing to do with the rotation of plummer, thus can rotate independently.What utilize uniqueness stretches out structure and blind hole structure, can ensure that basic fixed structure is constant while rising, thus can not affect the transmission of power transmission shaft and fix in the rotation of screw shell.Upward system tightly uses a drive motors, two kinds of motions that just can realize the rotation of Gear Processing is risen drive, ensure that the proportional precision between two kinds of motions simultaneously, therefore, the requirement of manufacturing equipment cost control can be met, the antagonism requirement of the cutting force for particular process material can be met simultaneously, and the form accuracy requirement of gear tooth slot can be met, it by the impact of processing environment confusion, does not all have for the maintenance of process equipment, the workflow management of process the tolerance degree increased.
