Description
Technical field
The present invention relates to a kind of gear of milling machine, relate in particular to a kind of progressive gear structure.
Background technology
The gear shift of general lathe is by porose disc or gear change hand lever control shift fork or shifting block; Then control the engagement and the disengagement of travelling gear; To realize what speed change was handled; These two kinds of manipulation process, a gear change hand lever can only be handled a shift fork or shifting block, realizes the engagement and the disengagement of a pair of duplex or nest; Porose disc is through the hole on it tooth bar to be promoted, through tooth bar rubbing gear, afterwards again by the gear plectrum carry-over bar; Tooth bar promotes engagement and disengagement that shift fork carries out gear is carried out and operates, more than two kinds of maneuverability patterns only be applicable to that general gearratio changes little transmission mechanism, for the bigger occasion of gearratio requirement; It is very big that gear will become; Carry out speed change if stir bigger gear again, the difficulty that will become relatively is because the speed change control crank is when promoting the gear wheel speed change; The resistance of operation can be very big, and the wearing and tearing between gear spline and the axle are also big especially; And stir the quantity that pinion will increase control crank, increase the unreliability of operation and the complexity of casing.
Summary of the invention
The purpose of this invention is to provide the good progressive gear structure of a kind of result of use.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: a kind of progressive gear structure, comprise casing, and have fixing hole on the casing; Be designed with revolving sleeve on the fixing hole, revolving sleeve is rotatably connected with casing relatively, it is characterized in that: the inner surface of revolving sleeve has the revolving sleeve arc groove; Be combined with handle set on the revolving sleeve, handle set is rotatably connected with revolving sleeve relatively, is fixedly connected handle on the handle set; Be designed with locating slot on the handle set, alignment pin is housed in the locating slot, be fixed with gyroaxis in the handle set; Have the gyroaxis arc groove on the gyroaxis, the left part of gyroaxis is connected with lower shake-changing arm and location-plate through key, is fixedly connected shifting shaft down on the lower shake-changing arm; Be plugged with second pinion on the following shifting shaft, second pinion is combined with second largest gear, and following shifting shaft is positioned at the second shifting shaft slot; The revolving sleeve left part is connected with upper rocker arm through key, is fixedly connected with shifting shaft on the upper rocker arm, and last shifting shaft is plugged with first pinion; First pinion is combined with first gear, and last shifting shaft is that the left end of revolving sleeve is fixedly connected with gland through screw in the first shifting shaft slot with first pinion.
Advantageous effect of the present invention is: because this structure of the present invention; So use the present invention only can carry out sequential operation to two pairs of gear meshing and disengagement, and can not produce maloperation, in the speed change of big speed ratio with an operating grip; Make operation to gear wheel or duplicate gear; Change the operation to pinion into, the power of can reducing friction on the one hand makes operation more convenient, flexible; Avoided the wearing and tearing that parts caused because of big frictional force that the gear stirred produces too greatly simultaneously, make simultaneously operate more convenient.
