Abstract
The utility model relates to a modified bent axle right side crank and an idol geared sleeve connection structure, the bent axle comprises left crank, crank pin, bearing, connecting rod, right crank, and the connecting rod passes through the big -end of connecting rod hole and bearing installs on the crank pin, and the external splines has been opened on one's body to right cranked rod, open in the idol geared sleeve have with right cranked rod body external splines matched with internal spline, through above -mentioned spline fit, an idol geared sleeve suit on one's body the cranked rod of the bent axle right side, its characterized in that: right side cranked rod also has an excircle step in the root of external splines, the internal spline one end of an idol geared sleeve also has interior round platform rank, and the length on above -mentioned interior round platform rank equals with the length of excircle step that the radius equals. The utility model discloses an increase by two stair structure and realize the location connection, increased the location area, effectively solved the phenomenon of bent axle installation abnormal sound.
Description
Technical field
The utility model belongs to technical field of engines, especially a kind of right crank of bent axle of improvement and couple geared sleeve linkage structure.
Background technique
Bent axle is the core component of motor, it is made up of left crank, crank pin, needle bearing, connecting rod, right crank, connecting rod is installed on crank pin by crank pin end pore and needle bearing, right toggle-action lever has spline with it, by this spline, right crank coordinates with couple inner spline gear wheel case and forms spline and link, thus plays mechanical transmission effect.The deficiencies in the prior art part is: there is abnormal sound after bent axle installation, need to be improved.
Summary of the invention
The utility model aims to provide a kind of right crank of bent axle and the couple geared sleeve linkage structure that efficiently solve the improvement of bent axle installation abnormal sound.
Technical solution of the present utility model is as follows:
A kind of right crank of bent axle of improvement and couple geared sleeve linkage structure, described bent axle is by left crank, crank pin, needle bearing, connecting rod, right crank composition, connecting rod is installed on crank pin by crank pin end pore and needle bearing, right toggle-action lever has external splines with it, couple geared sleeve has the internal spline matched with right crank shaft external splines, by above-mentioned spline fitted, couple geared sleeve is sleeved on it the right toggle-action lever of bent axle, it is characterized in that: described right toggle-action lever also has a cylindrical step in the root of external splines, also there is an inner circle step internal spline one end of described couple geared sleeve, the length of above-mentioned inner circle step is equal with the length of cylindrical step, radius is equal.
The utility model is on the right crank of traditional bent axle and couple geared sleeve linkage structure, location is realized by increasing by two ledge structures, increase location area, efficiently solve in prior art and only rely on that external splines and internal spline face are located, location area is little, easily produce abrasion, loosen near and cause the phenomenon of abnormal sound, ensure the fine transmission of spline structure.Achieve goal of the invention easily.
Accompanying drawing explanation
Below with reference to drawings and Examples, the utility model is described in further details.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is the structural representation of right crank shaft in the utility model embodiment.
Accompanying drawing 3 is the structural representation of couple geared sleeve in the utility model embodiment.
Accompanying drawing 4 is the structural representation of right crank shaft in prior art.
Accompanying drawing 5 is the structural representation of couple geared sleeve in prior art.
In accompanying drawing, each sequence number is respectively: 1, left crank; 2, crank pin; 3, needle bearing; 4, connecting rod; 5, right crank; 6, cylindrical step; 7, external splines; 8, couple geared sleeve; 9, inner circle step; 10, internal spline.
Embodiment
See accompanying drawing, the right crank of bent axle of the improvement shown in the utility model embodiment and couple geared sleeve linkage structure, described bent axle is made up of left crank 1, crank pin 2, needle bearing 3, connecting rod 4, right crank 5, and connecting rod 4 is installed on crank pin 2 by crank pin end pore and needle bearing 3.As shown in Figure 2, right crank 5 shaft has external splines 7, also has a cylindrical step 6 at the root of external splines 7.As shown in Figure 3, in order to ensure that couple geared sleeve 8 is in place, the internal spline 10 matched with right crank 5 shaft external splines 7 is had at couple geared sleeve 8 endoporus, an inner circle step 9 is processed in internal spline 10 one end, the length of above-mentioned inner circle step 9 is equal with the length of cylindrical step 6, and radius is equal.Coordinating and the location fit of external splines 7 and internal spline 10 by inner circle step 9 and cylindrical step 6, couple geared sleeve is sleeved on it the right toggle-action lever of bent axle.
The utility model embodiment realizes location by increase by two ledge structures, increases location area, ensures the fine transmission of spline structure, efficiently solves the phenomenon of prior art abnormal sound.
Above-mentioned drawings and Examples, only for illustration of the utility model, do not constitute any limitation protection domain of the present utility model.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model
