The spline housing achieves dual fixing by providing the fixing ring and providing the through holes on the fixing ring; the fixing firmness of the spline housing is increased; and the spline housing is more convenient to assemble and unassemble.
Description
Technical field
The utility model relates to spline housing, especially relates to the spline housing that can conveniently connect, and belongs to mechanical connection equipment.
Background technique
Splined is comprised of internal spline and external splines.Inside and outside spline is multiple tooth part, and the spline on inner periphery is internal spline, and the spline on outer cylinder surface is external splines.Obviously, splined is that flat key is connected in the development on number.
The effect of splined shaft: be that mechanical transmission is a kind of, the same with flat key, woodruff key, taper key effect, be all to transmit mechanical torque, the structure of splined shaft: the appearance at axle has keyway longitudinally, the revolving part that is enclosed within on axle also has corresponding keyway, can keep with the axle synchronous rotary.In rotation, what have can also do longitudinal sliding motion on axle, as the gearbox gear-shift gear etc.
Due to the difference of structural type and manufacturing process, connect with flat key relatively, splined has following characteristics in intensity, technique and use: because directly and equably making more tooth and groove on axle with on hub bore, therefore connect stressed comparatively even; Because groove is more shallow, tooth root place stress is concentrated less, and the strength reduction of axle and hub is less; The number of teeth is more, and total area of contact is larger, thereby can bear larger load; The centering of parts on shaft and axle is good, and this is very important to high speed and precision machinery; Guidance quality is good, and this is very important to moving connection; The method of available grinding improves machining accuracy and connects quality; Manufacturing process is more complicated, sometimes needs Special Equipment, and cost is higher.Applicable situation: the centering precision requirement is high, transmitting torque is large or the connection of frequent slippage.
Traditional spline is only to be connected with splined shaft, but spline self can't be connected with miscellaneous part, normally adopts the mode of offering tapped hole on spline to connect, caused the stress of spline to be damaged, affect the working life of spline, and the weak effect that connects, easily loosening.
The model utility content
It is shortcoming by perforate is fixed and fixed effect is poor that the purpose of this utility model is to overcome existing spline, a kind of spline housing that can conveniently connect is provided, this spline housing is by arranging retaining ring and offer through hole on retaining ring, realize dual fixing, increased the fix tightly soundness of spline housing, and loading and unloading are also convenient.
The purpose of this utility model is achieved through the following technical solutions: the spline housing that can conveniently connect, comprise cylinder, a wherein end of described cylinder is provided with retaining ring, this end face of cylinder and one of them end face of retaining ring are in same plane, cylinder is arranged on retaining ring inside and contacts with the inwall of retaining ring, be provided with several through holes on the end face of described retaining ring, and the axis of through hole is parallel with the axis of cylinder.
Further, described retaining ring comprises retaining ring one, retaining ring two and retaining ring three, wherein the inwall of retaining ring one contacts with the wall of cylinder, retaining ring two is arranged on the outside of retaining ring one, retaining ring three is arranged on the outside of retaining ring two, the inwall of retaining ring three contacts with the outer wall of retaining ring two, the inwall of retaining ring two contacts with the outer wall of retaining ring one, the bottom of the bottom of the bottom of retaining ring one, retaining ring two and retaining ring three and the end face of cylinder are in same plane, and through hole is arranged on the end face of retaining ring three.
Further, be provided with penetration hole in described cylinder, and the dead in line of the axis of penetration hole and cylinder, the outer wall of penetration hole protrudes and forms groove, and the two ends of groove are communicated with the two ends of cylinder simultaneously.
Further, the width of described groove is 14mm to 16mm.
Further, the width of described groove is 15mm.
Further, described column body arranges helix, and helix is arranged on the position between adjacent notches in groove.
In sum, the beneficial effect of model utility is: this spline housing is realized dual fixing by retaining ring being set and offering through hole on retaining ring, increased the fix tightly soundness of spline housing, and loading and unloading is also convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in accompanying drawing: 1-groove; 2-helix; 3-penetration hole; 4-cylinder; 5-retaining ring one; 6-retaining ring two; 7-retaining ring three; 8-through hole.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, the spline housing that can conveniently connect, comprise cylinder, a wherein end of described cylinder 4 is provided with retaining ring, this end face of cylinder 4 and one of them end face of retaining ring are in same plane, cylinder 4 is arranged on retaining ring inside and contacts with the inwall of retaining ring, be provided with several through holes 8 on the end face of described retaining ring, and the axis of through hole 8 is parallel with the axis of cylinder 4.Cylinder 4 is spline after penetration hole 3 is set, and becomes spline housing after retaining ring is set, by retaining ring and through hole are set, realize the dual of spline housing fixed, and the fastness when having increased fixedly, and relative and traditional spline, its loading and unloading have also been saved the time.
Described retaining ring comprises retaining ring 1, retaining ring 26 and retaining ring 37, wherein the inwall of retaining ring 1 contacts with the wall of cylinder 4, retaining ring 26 is arranged on the outside of retaining ring 1, retaining ring 37 is arranged on the outside of retaining ring 26, the inwall of retaining ring 37 contacts with the outer wall of retaining ring 26, the inwall of retaining ring 26 contacts with the outer wall of retaining ring 1, the end face of the bottom of the bottom of the bottom of retaining ring 1, retaining ring 26 and retaining ring 37 and cylinder 4 is in same plane, and through hole 8 is arranged on the end face of retaining ring 37.By the retaining ring of multilayer is set, can realize that retaining ring is combined with the tight buckle of miscellaneous part, the diameter of retaining ring 37 is maximum, between retaining rings at different levels, adopt the mode of welding to be connected between retaining ring 1 and cylinder 4, increases the fastness in fixing.
