Model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and the coupling arrangement of a kind of countershaft-gear and jack shaft is provided, and this device can effectively solve the problem that the countershaft-gear that causes due to tool withdrawal groove can not connect with jack shaft.
For achieving the above object, the coupling arrangement of countershaft-gear described in the utility model and jack shaft comprises jack shaft, second gear wheel and jump ring, on described jack shaft, be provided with successively one grade of wheel, positioning step, external splines, jump-ring slot and tool withdrawal groove, the inwall of second gear wheel is provided with the internal spline matching with the external splines of jack shaft; Second gear wheel is connected on the external splines of jack shaft by inner spline housing, and is axially fixed on jack shaft by positioning step and jump ring.
The large footpath of spline of described external splines is less than the outside diameter circle of one grade of wheel;
Described one grade of wheel shaft is to extending to dress second gear wheel place, and one grade of wheel prolongation is cut to part tooth top and uses as external splines;
Described second gear wheel endoporus processes the internal spline that the external splines that cuts part tooth top with one grade of wheel prolongation matches;
Described external splines is provided with jump-ring slot, and jump ring is contained in jump-ring slot, by loading jump ring axially locating two gear wheels in jump-ring slot.
The utlity model has following beneficial effect:
The coupling arrangement of countershaft-gear described in the utility model and jack shaft is by outwards shifting out tool withdrawal groove, and the part that tool withdrawal groove is outwards shifted out arranges external splines, the inwall of second gear wheel is provided with the internal spline matching with the external splines of jack shaft simultaneously, thereby adopt connecting mode that internal spline matches with external splines to substitute interference, add woodruff key connecting mode and be connected second gear wheel and jack shaft, and then the countershaft-gear that causes due to tool withdrawal groove of the solution problem that can not connect with jack shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of jack shaft 1 in the utility model;
Fig. 3 is the structural representation of second gear wheel 2 in the utility model.
Wherein, 1 for jack shaft, 1.1 for tool withdrawal groove, 1.2 for jump-ring slot, 1.3 be that one grade of wheel, 1.4 is taken turns, 3 is jump ring for second gear for external splines, 2 for positioning step, 1.5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1, Fig. 2 and Fig. 3, the coupling arrangement of countershaft-gear described in the utility model and jack shaft comprises jack shaft 1, second gear wheel 2 and jump ring 3, on described jack shaft 1, be provided with successively one grade of wheel 1.3, positioning step 1.4, external splines 1.5, jump-ring slot 1.2 and tool withdrawal groove 1.1, jump ring 3 is installed in jump-ring slot 1.2, and the inwall of second gear wheel 2 is provided with the internal spline matching with the external splines 1.5 of jack shaft 1; Second gear wheel 2 is connected on the external splines 1.5 of jack shaft 1 by inner spline housing, the left end of second gear wheel 2 positions by jump ring 3, the right-hand member of second gear wheel 2 is located by positioning step 1.4, thereby by positioning step 1.4 and jump ring 3, second gear wheel 2 is axially fixed on jack shaft 1.In addition, the large footpath of the spline of described external splines 1.5 is less than the outside diameter circle of one grade of wheel 1.3; Described one grade of wheel 1.3 axially-extending are taken turns 2 places to filling second gear, and one grade of wheel 1.3 prolongation is cut to part tooth item as external splines 1.5 uses; Described second gear is taken turns 2 endoporus and is processed with one grade of wheel 1.3 prolongation and cut the internal spline that the external splines of part tooth top matches; Described external splines 1.5 is provided with jump-ring slot 1.2, and jump ring 3 is contained in jump-ring slot 1.2, by loading jump ring 3 axially locating two gear wheels 2 in jump-ring slot 1.2.
The course of working of the coupling arrangement of countershaft-gear described in the utility model and jack shaft is:
In described jack shaft 1, the parameter of one grade of wheel 1.3 is identical with external splines 1.5, and external splines 1.5 and one grade of wheel 1.3 are used same parameters cutter to process at one time, and both differences are that the large footpath size of external splines 1.5 is less than the tip diameter of one grade of wheel 1.3.Processing one grade of wheel 1.3 rear cutter continues to be moved to the left, movable length is greater than withdrawing after second gear wheel 2 and jump-ring slot 1.2 width sums, form tool withdrawal groove 1.1, the difference of the tip diameter size of the large footpath size of external splines 1.5 and one grade of wheel 1.3 has formed positioning step 1.4.
Described second gear is taken turns 2 internal spline parameters and is matched with one grade of wheel 1.3 parameter, be that second gear is taken turns 2 inner rings and is designed to internal gear, its parameter is identical with one grade of wheel 1.3, after increasing internal gear path, as internal spline, use, after increasing, internal gear path is greater than the large footpath size of external splines 1.5, guarantee that internal spline can be inserted in external splines 1.5, in forming, external splines 1.5 connects, transmitting torque.
