Abstract
The utility model relates to the technical field of hydraulic torque converters, in particular to a toothed outer ring applied to a hydraulic torque converter, which is applicable to occasions with high requirements upon rotation speed and torque. The toothed outer ring comprise a guide roller and an outer shaft sleeve, the outer ring of the outer shaft sleeve is provided with wave-shaped hobbing, a clamp groove is annularly arranged on the outer ring and divides the same into a first outer ring and a second outer ring, the first outer ring and the second outer ring are integrated, the outer diameter of the first outer ring is smaller than that of the second outer ring, and the outer diameter of the outer ring of the outer shaft sleeve is larger than the diameter of the inner bore of the guide roller. The toothed outer ring solves the problem of complicated limit design between the guide roller and the outer ring, simplifies manufacturing and assembling processes of parts and saves cost.
Description
Technical field
The utility model relates to the fluid torque converter technical field, relates in particular to a kind of band profile of tooth outer ring that is applied to fluid torque converter.
Background technique
But fluid torque converter is the fluid power transmission component, and it is to utilize flowing of liquid reposefully Engine torque to be transferred to speed changer, and fluid torque converter inside is a ring device, wherein is full of automatic transmission fluid, between the speed changer of motor.The characteristics of fluid torque converter are: can eliminate shock and vibration, overload protection performance and starting performance are good; The rotating speed of output shaft can be greater than or less than input shaft rotational speed, and the speed discrepancy of diaxon is different with the size of transmitting torque; Good automatic speed changing performance is arranged, and output speed descended automatically when load increased, otherwise rose automatically; Guarantee that power engine has stable working area, the transient changing of load can not be reflected on the power engine substantially.
The design of the outer ring of outer shaft sleeve and guide wheel at present is comparatively complicated, assembly technology is comparatively loaded down with trivial details, and under the big condition of torque capacity, the problem that can produce relative rotation between the outer ring of external axle sleeve and the guide wheel is so need can be in identical design space maximum raising torque capacity.
The model utility content
The technical problems to be solved in the utility model is: in order to design needs, can produce relative rotation and design complexity, the loaded down with trivial details technical problem of assembling between the outer ring of solution external axle sleeve and the guide wheel.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of band profile of tooth outer ring that is applied to fluid torque converter, it comprises guide wheel and external axle sleeve, surface, the outer ring undulate gear hobbing of external axle sleeve, described outer ring is equipped with draw-in groove, draw-in groove is divided into first outer ring and second outer ring with the outer ring, first outer ring and second outer ring are structure as a whole, and the external diameter of first outer ring is less than the external diameter of second outer ring, and the outer ring external diameter of described external axle sleeve is greater than the endoporus of guide wheel.
For the ease of can directly being pressed into assembling, described guide wheel material is the aluminum metal with high ductility.
As preferably, the degree of depth and the width of described draw-in groove are 1～3mm, and the width of described first outer ring is 1.2～3.2mm.
The beneficial effects of the utility model are, a kind of band profile of tooth outer ring that is applied to fluid torque converter of the present utility model is specially adapted to high rotating speed and the also high occasion of torque demand, the external axle sleeve of band gear hobbing shape outer ring wherein, utilize the characteristics that are pressed into guide wheel material higher ductility cleverly for aluminum metal has, though the diameter of outer ring is greater than the endoporus of guide wheel, but because the high ductibility of aluminum metal can directly be pressed into assembling, process is simple.After assembling was pressed into, the space at outer ring tooth root place was filled up by the guide wheel material, had limited the outer ring and had rotated possibility.Simultaneously, be pressed into the end draw-in groove and filled by the guide wheel material equally, volitional check axial the moving in outer ring.The utility model has solved spacing design complicated between guide wheel and the outer ring, has simplified technology manufacture process, the assembly process of part, provides cost savings simultaneously.
Description of drawings
Fig. 1 is a kind of structural representation that is applied to the band profile of tooth outer ring of fluid torque converter of the utility model.
Fig. 2 is the right elevation of Fig. 1.
1. waveform gear hobbings among the figure, 2. draw-in groove, 3. first outer ring, 4. second outer ring.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As a kind of embodiment who is applied to the band profile of tooth outer ring of fluid torque converter of Fig. 1 the utility model shown in Figure 2, it comprises guide wheel and external axle sleeve, surface, the outer ring undulate gear hobbing 1 of external axle sleeve, described outer ring is equipped with a circle draw-in groove 2, draw-in groove 2 is divided into first outer ring 3 and second outer ring 4 with the outer ring, first outer ring 3 and second outer ring 4 are structure as a whole, and the external diameter of first outer ring 3 is less than the external diameter 2mm of second outer ring 4, and the outer ring external diameter of described external axle sleeve is greater than the endoporus of guide wheel.
For the ease of can directly being pressed into assembling, described guide wheel material is the aluminum metal with high ductility.
As most preferably, the degree of depth and the width of described draw-in groove 2 are 2mm.
As most preferably, the width of described first outer ring 3 is 2.2mm.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
